Description
Technical Field
The invention belongs to the technical field of cable stripping, and particularly relates to a knob type stripper.
Background
Along with the continuous development and progress of society, the scale of power distribution network construction is also continuously expanding, and the operation, maintenance and overhaul workload of the power distribution network is increased. In order to improve the power supply reliability and reduce the number of users in power failure, the working importance of live working is gradually increased. In the process of welding lines, the stripping of an insulating wire sheath, namely an insulating sheath, is an important process in wire stripping connection. Existing cable stripping modes are divided into manual stripping and automatic stripping. When live working is implemented by manually utilizing potential entering and exiting tools such as an insulating arm vehicle or an insulating platform, not only are operators in direct contact with live wires, but also unsafe factors are increased, meanwhile, the stripping difficulty is high, the number of working steps is large, the efficiency is low, the working environment is also easily influenced by the geographical environment, and the automatic stripping is gradually replaced. For example, the patent with publication number of CN 201829799U discloses a cable knob stripper, which is driven by electric power to drive a blade to rotate around a cable by a crank-link mechanism to realize circular cutting action, thereby stripping insulation skin. Meanwhile, similar descriptions are given in the patent texts with the publication number of CN 108963888A and the publication number of CN 206432551U, and even the applicant has applied for the patent text with the application number of CN 109119946A, namely, the utility model of a cable electric peeling device. Through reading the existing peeling structure, the peeling device in the market at present has a common defect that the zero position of the cutter cannot be adjusted on line. Specifically, when the thickness of the insulating sheath of the cable is equal and the outer diameters of the cable are different, different feeding amounts need to be adjusted to achieve the same cutting depth so as to achieve the effect of completely stripping the insulating sheath without damaging the wire core. However, the zero position of the cutter of the existing knob peeler can only be adjusted in a preset mode in an off-line mode; when the cable stripping operation is performed, frequent operations of inserting the cable into the stripping jig are required, and whether the preset feeding amount is enough or not is visually observed in the process. Once too much or too little feed is found, the knob stripper is removed from the cable, the feed of the cutter at the knob stripper is deepened or shallowed a little, and then the visual inspection process is repeated until the feed of the cutter is consistent with the actual required cutting depth of the cable. The cables of each model are peeled once, and the adjustment operation is carried out for a plurality of times, so that the adjustment process is extremely complicated, and the actual cable peeling efficiency is seriously influenced. Furthermore, another saliency problem in the prior art is the joint adjustment of the feed depth and feed angle of the tool. Because the insulating wire sheath, commonly called insulating sheath, is made of high-strength polyethylene material, the thickness and the hardness are very large, the cutter is required to have proper cutting depth, and a specific optimal cutting angle is required to be matched, so that a reliable insulating sheath stripping function can be realized. The existing peeling structure often neglects the adjustment of the feed angle, and focuses on the adjustment of the feed depth only. Obviously, by means of the single feeding angle adjusting operation, when the angle of the cutter is too large, the hardness of the cable insulation skin to be peeled is high, and even the cutter bending and breaking phenomenon can occur. When the cutter angle is too small, the efficiency is low when the thick insulating skin peeling operation is carried out, and the wire core can be peeled out by repeatedly cutting the wire core for a plurality of times by the knob type peeler, so that the high-efficiency modernization peeling requirement is not facilitated. If the problem is to be solved, the mode that the knob peeler with the cutter with the specific angle is matched with the cable with the specific model is only needed, but the actual peeling cost is obviously increased, and the single carrying amount of operators is increased, so that a plurality of troubles are brought to the actual operation. meanwhile, when the cable is peeled, the peeling clamp at the knob peeler is not only required to hold the cable, but also required to rotate to peel the cable, and how to hold the cable with proper force is also a technical problem to be solved in recent years in the field.

The invention has the beneficial effects that:
1) On the basis of the structure of the existing stripper, the invention provides a manual control zero reference adjusting structure, so that the manual adjusting function of the cutter feed amount can be flexibly realized according to the diameter of the cable to be clamped at present. Specifically, when the tool depth adjusting knob is manually screwed to drive the tool depth adjusting bolt until the annular bulge at the tool depth adjusting bolt is matched with the pressing plate together to clamp the tool depth adjusting screw seat in opposite directions, the tool tip of the tool and the reference part are positioned on the same horizontal line; meanwhile, the tool depth adjusting screw seat is fixedly connected with the zero position reference slide plate, so that the zero position reference slide plate, the reference part, the tool depth adjusting screw seat and even the tool depth adjusting slide block are fixedly connected with each other to form an integrated structure, and the elastic floating action can be generated relative to the upper clamping plate and the pressing plate under the action of the elastic compression damping piece. Once the upper clamping plate is matched with the lower clamping plate to wrap the cable, the reference part is pushed to float upwards under the action of the elastic compression damping piece, and meanwhile, the cutter and the reference part are integrated, so that the cutter can float upwards synchronously, and zero reference correction operation is completed. Then, the cutter depth adjusting knob is used for driving the rotating sleeve to rotate, so that the cutter depth adjusting bolt generates spiral descending action, and the cutter can slowly cut into the cable insulation skin along with the integral rotation of the peeling clamp under the action of the elastic restoring force of the elastic compression damping piece. When the cutter depth adjusting bolt descends by one centimeter, the cutter can sink by one centimeter in absolute mode relative to the reference part or the uppermost bus of the cable insulation cover, and finally the purpose of adjusting the consistency of the cutter feeding amount and the actual required cutter depth of the cable is achieved, and the effect of adjusting the absolute cutter depth is achieved. Of course, in actual operation, the contact position of the cutter and the reference part does not necessarily need to be the uppermost bus of the cable insulation cover, only the action paths of the cutter and the reference part need to be arranged along the radial direction of the cable, and the contact position of the cutter and the reference part relative to the cable insulation cover is the same bus of the cable insulation cover, so that the description is omitted.
Under the above structure, when the knife depth adjusting knob continuously drives the rotary sleeve to rotate and the knife depth adjusting bolt continuously descends, the knife can continuously deepen the absolute knife depth of the cable insulation cover. Once the cutter tip just stretches into the cable insulation skin completely and begins to expose the cable core, the rotation of the cutter depth adjusting knob can be stopped so as to keep the current cutter depth and achieve the purpose of continuously perfectly cutting the cable insulation skin. Of course, more preferably, the model of the cable to be peeled is predicted, so that the insulation skin depth of the current cable is obtained, and further, the rotation cycle number of the cutter depth adjusting knob is manually controlled, so that the cutter point can be ensured to peel the insulation skin of the cable to the extent that the cable core is exposed, namely, the cutter point stops to extend continuously, and the peeling efficiency is ensured.
2) When the cable clamping and fixing device is used for clamping and fixing cables each time, the aim of synchronous approaching and separating actions of the upper clamp seat relative to the lower clamp seat can be achieved through the forward and reverse rotation action of the opening and closing driving motor. In actual operation, the invention is additionally provided with the sensing part on the basis of the structure, and the sensing part can adopt the existing sensing structure such as a travel switch, even an electronic sensor and the like, so that the position of the sensing part is adjusted through the vertical travel action of the sensing part, and the distance adjusting function of the peeling clamp during the cohesion action of the two groups of clamp seats is realized. When the cable is required to be clamped, the position of the sensing part is adjusted, and the clamping seat and the lower clamping seat are synchronously operated by virtue of the bidirectional screw rod in the prior art, so that the sensing part at the position of the upper clamping seat is only required to generate induction stop action when the opening is adjusted during clamping. In other words, the invention can realize the position stopping function of the upper clamp seat through the lifting and positioning actions of the sensing part every time the cable clamping and fixing are carried out. When the upper clamp seat moves relatively to the lower clamp seat to the position that the matching part contacts or senses the sensing end of the sensing part, the opening and closing driving motor stops acting, so that the peeling clamp is ensured to hold the cable with the most proper force. Because the peeling clamp is required to hold the cable and simultaneously rotate the cable to peel, the proper force is required to be adjusted timely and pertinently according to the mechanism of the invention. When the sensing part descends by one centimeter, the clamping gap between the upper clamp seat and the lower clamp seat which act synchronously in opposite directions is reduced by two centimeters, the diameter of the corresponding clamped cable is two centimeters thinner than that of the cable which is clamped originally, and the like, so that the cable clamping device is extremely convenient to use.
3) Further, for the operation mode of the sensing part, various structures can be adopted for realizing in actual use: if the sensing part is driven by the air cylinder to generate vertical lifting action, the function of changing the position of the sensing end at the sensing part is realized, and the aim of adjusting the stop position of the corresponding clamp seat is further realized. The sensing part serving as the sliding block can be driven to generate vertical lifting action in a crank rocker mode, so that a corresponding adjusting effect is realized. The invention preferably adopts the action of the opening adjusting screw and the screw rod sliding block of the sensing part to realize the manual position adjustment of the corresponding clamp seat: in actual operation, through the rotary action of the opening adjusting knob, the rotary action can be converted into the linear up-and-down reciprocating action of the sensing part through the opening adjusting screw rod, the structure is simple, the implementation is easy, and the cost performance is extremely high.
4) Further preferable embodiments of the above-mentioned embodiments are characterized in that the guide device is used for a frame of a base body for placing the swivel sleeve and the sensor part, and an upper right-angle V-shaped groove is correspondingly formed, so that the reliability and the accuracy of the vertical lifting operation of the sensor part are ensured by the guide function of the vertical groove cavity of the upper right-angle V-shaped groove and by matching with the opening adjusting screw. In addition, the swivel sleeve is matched with the swivel hole by virtue of the small shaft diameter section; on the other hand, the top end of the small shaft diameter section is in spline fit with the opening adjusting knob; therefore, the shaft shoulder of the rotary sleeve and the bottom end surface of the opening adjusting knob are clamped on the sealing plate in opposite directions, so that the rotary sleeve is ensured to be reliably matched with the frame, and meanwhile, the stable rotary function of the rotary sleeve is ensured, and the rotary sleeve is very convenient to disassemble and assemble.
5) On the basis of the structure, the observation hole is matched with the scales and the indication arrows, so that when the sensing part generates vertical lifting action, the indication arrows at the corresponding sensing heads can relatively stand still to the scales at the rack to generate vertical lifting action. The corresponding scales are drawn according to the cable sizes which are needed to be used in the present places. During actual operation, only need look at the cable model that needs to skin at a glance, can the pertinence rotate opening adjust knob, and then go up and down to the scale department that aims at corresponding above-mentioned model cable through the instruction arrow to realize the position calibration purpose of sensing portion. Once the position of the sensing part is determined, the stop position of the corresponding upper clamp seat during descending motion can be determined, and then the purpose of determining the size of the clamping opening of the upper clamp seat relative to the lower clamp seat can be realized, and at the moment, the corresponding cable can be clamped by the most suitable force so as to facilitate the follow-up peeling process.
6) As previously mentioned, the sensing portion may be implemented in practice using a structure such as an electronic sensor. The present invention preferably uses a travel switch to simplify its structure. When a travel switch is selected as the sensing portion, a horizontal toggle should be arranged on the back surface of the upper jig base to form the fitting portion. In actual operation, the arrangement of the sensing part can ensure that the cable can be clamped by proper cohesion degree when the two clamp seats synchronously and similarly act; meanwhile, the invention also adds a down travel switch to realize the limiting purpose of the maximum opening amplitude of the two clamp seats when the two clamp seats do the separation action. Through the limitation of the maximum opening amplitude, the occurrence of idle work can be effectively avoided, and the actual use efficiency of the invention is effectively ensured. Of course, the lower clamp seat can be used as the matching piece of the sensing part in specific use, and the upper clamp seat can be used as the matching piece of the lower travel switch, so that the purpose of overall control of the opening and closing amplitude of the peeling clamp can be achieved, and the details are not repeated here.
7) For the opening adjusting screw rod, the opening adjusting screw rod and the rotary sleeve are in detachable spline type matching, so that the convenient dismounting function of the invention is ensured, and the reliable torque transmission to the opening adjusting screw rod after the rotary sleeve is installed is ensured.
8) In the reference part, the contact function of the insulating sheath of the opposite cable can be realized by adopting a straight rod or the like in the actual operation, or the contact matching effect can be realized by adopting a rectangular block with a ball at the front end and the like. The zero reference bearing is preferably adopted to realize the reference calibration function: the zero reference bearing can not only realize the contact effect of the insulation skin of the relative cable, but also generate bearing rolling action relative to the surface of the cable when the peeling clamp rotates relative to the cable so as to reduce the rotation resistance of the peeling clamp relative to the surface of the cable, thereby effectively improving the convenience and peeling efficiency of the whole peeling operation.
9) Further, the upper clamping plate and the lower clamping plate are matched with each other through the V-shaped cohesion surfaces of the V-shaped cohesion plates to realize the cohesion function of the opposite cables. When the V-shaped holding plate is arranged at the bottom end surface of the upper clamping plate, if the coverage area of the V-shaped holding plate is enlarged, the action path of the reference part can be interfered; if the coverage area of the V-shaped embracing plate is reduced, the embracing effect relative to the cable may be reduced. According to the invention, the yielding port is directly formed in the V-shaped holding plate so as to enable the reference part to normally pass, so that the coverage area of the V-shaped holding plate is ensured, and the normal zero reference correction function of the reference part is ensured, and multiple purposes are achieved.
10 For elastic compression damping members, structures such as elastic damping air bolts or even hydraulic damping bars can be used. The invention preferably adopts a traditional guide post and spring matching structure, so that two groups of compression springs are matched through two guide posts, and the purpose of accurate vertical guiding of the cutter depth adjusting slide block is ensured while the elastic matching function of the cutter depth adjusting slide block relative to the pressing plate is ensured.
11 For the matching structure of the zero reference slide plate and the upper clamping plate and the knife depth adjusting slide plate and the zero reference slide plate, the reliable vertical sliding matching function of the zero reference guide rail and the knife depth adjusting guide rail can be ensured to ensure the online sliding adjustment purpose.
12 The tool apron is used as a fixed body, the tool bit is used as a working end, and the adjusting handle is used as an intermediate connecting piece, so that the aim of adjusting the arc-shaped action of the tool bit relative to the tool apron is fulfilled. Because the adjusting handle and the tool apron form a guide rail sliding block matching relation with the guide direction of arc action, and the circle center of an arc action path generated by the adjusting handle relative to the tool apron is the point of the tool nose of the tool bit; therefore, no matter how the adjusting handle is driven, the cutter head always generates arc-shaped rotation action taking the cutter tip as the center of a circle, so that the function of changing the cutting angle of the cutter blade is realized, the cutter head is ensured to be always and accurately abutted against the initial cutting point preset at the insulating skin no matter how the cutter head is adjusted, and finally, the purpose of rapidly stripping the insulating skin can be stably and reliably realized under the follow-up action of the zero-position reference adjusting assembly.
13 For the guide rail matching structure between the adjusting handle and the tool apron, various implementation schemes can be adopted in actual use: if the guiding sliding rail is arranged at the adjusting handle, the sliding block structure is arranged on the tool apron, so that the guiding matching function of the guiding sliding rail is realized through the matching of the guiding sliding rail and the sliding block. The adjusting handle can be provided with a penetrating arc hole, and the tool apron is provided with a locating pin which stretches into the arc hole so as to realize the radian guiding function. The invention preferably uses the matching structure of the groove and the convex rib to be matched with the fixed screw to be fixedly connected with the screw thread of the opposite tool apron so as to ensure the on-line adjusting function of the adjusting handle relative to the tool apron. On one hand, the matching structure of the corresponding grooves and the convex edges ensures that the whole processing process tends to be shallow processing, and the processing technology requirement is lower. On the other hand, through the cooperation structure of the arc-shaped fixing holes and the fixing screws, the action surface on the whole structure is positioned at one side of the tool apron, and the operation of the invention can be completely finished at one side of the invention, and the invention is particularly suitable for being used in a narrow working environment where the invention is positioned. In addition, the corresponding grooves and the convex edges are matched to form a group of arc-shaped actuating mechanisms, and the fixing screws are matched with the arc-shaped fixing holes to form a group of arc-shaped actuating mechanisms in practice. According to the double-arc-shaped guiding mode, the accurate arc-shaped swinging function of the cutter head can be achieved to the greatest extent, the cutter head is always ensured to be nailed at the initial cutting point preset at the insulating skin when the angle of the cutter head relative to the cutting edge of the insulating skin changes, and the working reliability of the cutter head is extremely high.
14 Further, the cutter head has the function of adjusting the cutting angle of the cutting edge, and the rotary adjusting function around the axis of the cutter head can be realized through a unique cylindrical structure of the cutter head. Through the rotation adjustment, on one hand, the vertical height of the arc-shaped cutting edge of the cutter head can be always ensured to be larger than the total thickness of the insulating leather during cutting feed, on the other hand, the best lateral chip guiding and removing effect can be achieved, and the optimal insulating leather cutting purpose can be achieved by matching with the adjustment of the cutting angle of the cutting edge. In addition, the cylindrical or semi-cylindrical cutter head can generate huge cutting force when cutting the insulating skin, and the cutter head can also have enough rigidity and strength to bear the reverse force so as to ensure the practical service life of the integral component.
15 The equipotential shrapnel is elastically abutted against the surface of the cable insulation skin only under the action of the surrounding hoop cable of the peeling clamp due to the existence of the cable insulation skin at the surface of the cable at the beginning. When the cutter is peeled, the cable insulation cover is gradually removed and the wire core is exposed, at the moment, the equipotential shrapnel can act to contact the wire core due to the elastic restoring force of the equipotential shrapnel, and the high-voltage current at the wire core is connected with the circuit board of the robot so as to form the equipotential operation effect, thereby ensuring the automation of the robot.
16 The arrangement of the skin guiding device can lead the hard insulating skin of the cable cut by the cutter to be guided out of the working range of the invention in time so as to avoid the cut insulating skin interfering with the normal work of the invention, thereby further improving the working reliability of the invention.

Detailed Description
For ease of understanding, the specific structure and operation of the present invention is further described herein with reference to FIGS. 1-23:
The peeling clamp is mainly composed of a peeling clamp 50 and a driving unit 40; after the assembly of the application is completed, the cable stripping device can be finally fixed on external devices such as an axial follow-up mounting rack, a robot arm, even a handheld insulating rod and the like through the transfer rack, so as to achieve the purpose of stripping the high-altitude cable. The combination of the peeling clamp 50 and the driving unit 40 has been disclosed before, and will not be described in detail, the present application is mainly described herein as the modified peeling clamp 50.
The peeling clamp 50 includes a zero reference adjustment assembly, a feed angle adjustment assembly, a clamp opening adjustment assembly, an axial displacement helix angle adjustment assembly, a skin guide 52w, and an equipotential spring 53 a.
The following description will be given in order:
1. Zero reference adjustment assembly:
The zero reference adjustment assembly is specifically configured as shown with reference to FIGS. 1-4 and 6-10 and is assembled directly with the tool 56 and the rear thread blocks 50a to form the upper clamp seat 52 in use. Referring to fig. 6-8, the zero reference adjustment assembly includes, from left to right, an upper clamp plate 52j, a zero reference rail 52u, a zero reference slide plate 52a, a depth of blade adjustment rail 52v, a depth of blade adjustment slider 52b, and a reference portion 52k, respectively. The right side of the knife depth adjusting slide block 52b is provided with a reference positioning plate 52o horizontally protruding outwards, and a plumb reference hole is formed in the reference positioning plate 52 o. In the layout structure shown in fig. 8, a tool depth adjusting bolt 52f is fitted to the hole axis at the vertical reference hole; further, a depth adjusting screw seat 52d, a pressing plate 52c, an elastic compression damper 52e, a rotary sleeve 52g and a depth adjusting knob 52h are sequentially provided upward in the axial direction of the depth adjusting bolt 52 f.
The concrete assembly is as follows:
As shown in fig. 6-8, the upper clamping plate 52j serves as a skeleton of the upper clamping seat 52, the bottom end of which is provided with a V-shaped holding plate 52q, and the top end of which is formed with an integral right-angle bending plate structure by bolting with the pressing plate 52 c. The zero reference guide rail 52u is fixedly connected to the left side, i.e. the outer side plate surface of the upper clamping plate, so that the zero reference slide plate 52a positioned at the outer side plate surface of the upper clamping plate can form a guide rail matching relationship with the upper clamping plate, wherein the guide direction of the guide rail is vertical, through the zero reference guide rail 52 u. Similarly, a knife depth adjusting guide rail 52v is arranged at the outer side plate surface of the zero reference slide plate 52 a; and the tool depth adjusting slide block 52b positioned on the outer side plate surface of the zero position reference slide plate 52a forms a guide rail matching relationship with the zero position reference slide plate 52a in a vertical direction by the tool depth adjusting guide rail 52 v. The top end surface of the zero reference slide plate 52a and the tool depth adjusting screw seat 52d form an integrated right-angle bending plate structure, and the bottom end surface of the zero reference slide plate 52a is connected with a reference part 52k, namely a zero reference bearing, through a bearing seat 52 p.
The top end of the tool depth adjusting slider 52b is provided with a guide post 52s vertically arranged along the axis in a vertical direction as shown in fig. 6-8, and the top end of the guide post 52s penetrates through the pressing plate 52c to form guiding fit with the guide hole at the pressing plate 52 c. The elastic compression damper 52e may be coaxially assembled on the guide post 52s by using a compression spring or even a damping air column, so as to achieve the similar elastic force accumulation action of the blade depth adjusting slider 52b relative to the pressing plate 52c and the separate elastic force release action under the elastic restoring force. The bottom end of the tool depth adjusting slider 52b is fixedly connected to the tool holder 56a of the tool 56 by a bolt as shown in fig. 6 to 8. In actual operation, referring to the structure of the tool holder 56a shown in fig. 15-20, a corresponding kidney-shaped assembly hole is provided on the tool holder 56a, so that the purpose of adjusting the tool in a horizontal direction to a certain extent can be achieved when the slider 52b is adjusted in cooperation with the tool depth.
As shown in fig. 6-8, a horizontal protruding reference positioning plate 52o is provided on the outer side plate surface of the blade depth adjusting slider 52b, a vertical reference hole is provided on the reference positioning plate 52o, and a protruding annular radial protrusion 52l is coaxially protruding on the bottom end surface of the blade depth adjusting bolt 52 f; the upper ring surface of the radial bulge 52l is matched with the lower plate surface of the reference positioning plate 52o to form a one-way spigot. Meanwhile, after the tool depth adjusting bolt 52f is in threaded fit with the tool depth adjusting threaded seat 52d, the top end surface of the tool depth adjusting bolt 52f also coaxially penetrates into the barrel cavity of the rotating sleeve 52g, and the torque transmission type matching structure capable of axially sliding and circumferentially limiting is realized through the matching of the limiting boss 52n and the limiting slot hole 52m as shown in fig. 7. The top end of the rotary sleeve 52g is fixedly connected with the power output shaft of the knife depth adjusting knob 52h positioned on the upper plate surface of the pressing plate 52c through a radial fixing structure capable of transmitting torque by a set screw structure, even a spline fit mode, so as to ensure the torque transmission function of the rotary sleeve 52g and even the knife depth adjusting bolt 52 f.
When the operator manually turns the tool depth adjusting knob 52h to rotate it, an axial downward force is applied to the tool depth adjusting bolt 52f by rotating the sleeve 52g, so that the tool tip of the tool 56 located at the tool depth adjusting slider 52b moves downward, thereby realizing the function of deep cutting of the cable insulation cover. When the knife depth adjustment knob 52h continuously drives the rotation sleeve 52g to rotate and the knife depth adjustment bolt continuously descends, the knife 56 continuously deepens the absolute knife depth relative to the cable insulation cover. Through visual judgment of operators, once the cutter tip of the cutter 56 just stretches into the cable insulation skin completely and begins to expose the cable core, the cutter depth adjusting knob 52h is rotated in place and kept in situ, so that the current cutting depth is maintained and the continuous perfect cutting purpose of the cable insulation skin is achieved. Of course, it is more preferable to predict the type of the cable to be stripped, thereby obtaining the insulation skin depth of the current cable, and further, by controlling the rotation cycle number of the knife depth adjusting knob 52h, ensuring that the knife tip of the knife 56 can be stripped to the extent that the cable insulation skin is bared, i.e. stop extending continuously, so as to ensure the stripping efficiency.
Of course, during actual operation, the visual operation mode may be replaced by an induction operation mode similar to a conventional photoelectric sensing portion such as a camera sensing portion, or even an existing conventional detection means such as discharge detection or electromagnetic field induction, and even the signal transmission and receiving and transmitting modes of the conventional detection means are conventional operation modes in the electronic sensing field, which will not be described herein.
2. A feed angle adjusting component:
The structure of the feed angle adjusting assembly is shown with reference to fig. 1-4 and 15-20. The feed angle adjusting assembly includes a cutter head 56b as a mounting base for cutting the insulating cover, a cutter seat 56a as a mounting base for the cutter head 56b, and an adjusting handle 56c for engaging the cutter head 56b with the cutter seat 56 a. The tool holder 56a is fixed to the bottom end surface of the depth adjusting slider 52b of the zero reference adjusting assembly by a conventional known engagement means such as a screw engagement, so as to be capable of being lifted and lowered in the same manner as the depth adjusting slider 52 b.
The outer shape of the adjustment lever 56c is a trapezoidal plate shape as shown in fig. 15 to 16, and the inner plate surface of the adjustment lever 56c forms an abutment surface for engaging with a vertical engagement surface at the tool holder 56 a. The trapezoid top edge of the adjusting handle 56c extends toward the tool holder 56a to form an engaging plate 56h, and the plate surface of the engaging plate 56h is perpendicular to the plate surface of the adjusting handle 56 c. As can be seen in the structure shown in fig. 15-20, the abutment surface of the adjusting handle 56c is provided with an arc-shaped rib 56d, and the plumb mating surface of the tool holder 56a is provided with an arc-shaped groove 56e, and the arc-shaped extending path of the arc-shaped rib 56d and the arc-shaped groove 56e is located on the same circle with the tool tip of the tool bit 56b as the center of a circle and the distance between the tool tip of the tool bit 56b and the corresponding groove or rib as the radius. Meanwhile, an arc-shaped fixing hole 56g is horizontally penetrated and arranged at the position of the adjusting handle 56c, and a concentric circle layout is formed between the radian extension path of the arc-shaped fixing hole 56g and the radian extension path of the arc-shaped convex rib 56 d. The fixing screw 56f horizontally penetrates into the arc-shaped fixing hole 56g, and the top end of the fixing screw 56f is in threaded fixedly connection with the vertical matching surface of the tool holder 56a, so that the adjusting handle 56c is horizontally pressed and fixed on the tool holder 56a by the nut end of the fixing screw 56 f.
The shape of the tool bit 56b is also taught: as shown in fig. 15-19, the profile of the bit 56b actually assumes a cylindrical configuration with a slant downward. The rear section of the cutter head 56b forms the handle end of the cutter head 56b, and a counter bore is coaxially concavely arranged at the top end of the front section of the cutter head 56b, and an inner chamfer is arranged at the orifice of the counter bore. The cutting head 56b is cut with a cutting plane coincident with the axis of the cutting head 56b so that the front section of the cutting head 56b assumes a semi-cylindrical configuration, and the inner chamfer cut at the counter bore at this time constitutes a semicircular arc-shaped cutting edge 56j. The structure of the cutter head 56b can always ensure that the vertical height of the arc-shaped cutting edge of the cutter head 56b is larger than the total thickness of the insulating skin during cutting and feeding; on the other hand, the best lateral chip guiding and removing effect is achieved, and the optimal insulation skin cutting purpose can be achieved by matching the adjustment of the cutting angle of the cutting edge 56j. In addition, the cylindrical or semi-cylindrical bit 56b generates a significant cutting force when cutting the insulating sheath, and the bit 56b itself can be sufficiently rigid and strong to withstand its opposing forces to ensure the practical life of the integral component.
3. A clamp opening adjustment assembly:
The structure of the clamp opening adjustment assembly is shown with reference to fig. 2-5; the rear thread sliders 50a are disposed on the back surfaces of the upper and lower clamp bases 52 and 53 so as to form a thread fit relationship with the screw rod sections of the bidirectional screw rod 54, so that the upper and lower clamp bases 52 and 53 can generate opposite and separate actions parallel to the axis of the bidirectional screw rod 54 under the driving of the opening and closing driving motor 55 or other power equipment. In order to ensure the stability of the operation of the upper and lower clamp holders 52, 53, the frame 51 is further provided with a vertical rail 51i, and the rear screw slider 50a is engaged with the vertical rail 51i through a rail corresponding to the vertical slider 51 j.
In practice, the present invention contemplates a portable adjustment device for manual adjustment of the peeling clamp 50, i.e., the clamp opening adjustment assembly described above. As shown in fig. 5 and 11-14, the jig opening adjustment assembly includes an opening adjustment knob 51k, an upper right angle V-shaped groove 51a, a swivel case 51j, a sensor portion 51n, an opening adjustment screw 51m, a lower bracket block 51f, and a lower travel switch 51h, which are arranged in this order from top to bottom. In actual operation, when the vertical guide rail 51i is mounted on the inner side plate surface of the C-shaped plate-like frame 51 as shown in fig. 4-5, the upper right angle V-shaped groove 51a and the lower support block 51f are mounted on the outer side plate surface of the frame 51 in sequence from top to bottom. Meanwhile, the upper right-angle V-shaped groove 51a can be split into a lower section body for guiding the sensing part at the lower part and an upper section body with a rotation hole at the upper part, so that the opening adjusting screw 51m and the rotation sleeve 51j can be conveniently assembled. And the lower support block 51f is correspondingly provided with a lower right-angle V-shaped groove 51g. The upper right angle V-shaped groove 51a and the lower bracket 51f may be assembled to the outer plate surface of the frame 51, and the assembly sequence of the opening adjustment knob 51k, the swivel bush 51j, the sensor portion 51n, the opening adjustment screw 51m, and the lower travel switch 51h may be assembled as shown in fig. 5.
In the peeling process, the arrangement of the sensing part 51n can ensure that the cable can be held by proper holding strength when the two clamp seats synchronously and similarly act; meanwhile, the invention further adds a down travel switch 51h to realize the limiting purpose of the maximum opening amplitude when the two clamp bases do the separation action. Specifically, in the assembled state of fig. 5 and fig. 11-14, in which the upper holder 52 is matched with the sensing portion 51n, and the lower holder 53 is matched with the lower travel switch 51h, the sensing portion 51n can realize the opening minimum calibration function of the opposite movement, i.e. the closing movement, of the peeling clamp 50 through the matching with the horizontal pulling tongue 50b at the upper holder 52. The lower travel switch 51h can be used for ensuring the guiding and adjusting action purpose by referring to the sensing part 51n, and can be used for realizing the opening maximum value calibration function of the separating action, namely the opening action, of the peeling clamp 50 by being matched with a screw at the fixed point of the horizontal pulling tongue 50b at the lower clamp seat 53, and even the lower travel switch 51h can be directly fixed on the lower support block through threads, so that the fixed point is fixed. Specifically when the screw to the fixed point cooperates the operation, can run through on the lower travel switch 51h and set up the location hole of passing through, but the perpendicular preface that sets up multiunit location cooperation hole of right angle V type groove 51g department to through the pertinence of location cooperation screw, thereby realize the height fixation function in lower travel switch 51h relative lower right angle V type groove 51g cell chamber. An operator only needs to look at the type of the cable to be peeled, and can correspondingly rotate the opening adjusting knob 51k, so that the arrow 51e is indicated to act to align with the scale 51d of the cable corresponding to the type as shown in fig. 4 and 11, and finally, the purpose of calibrating the position of the sensing part 51n is achieved conveniently through timely observation of the observation hole 51 c. Once the position of the sensing part 51n is determined, the stop position of the corresponding upper clamp seat 52 when the upper clamp seat 52 descends can be ensured, and accordingly, the purpose of determining the minimum value of the clamping opening of the upper clamp seat 52 relative to the lower clamp seat 53 can be realized; the fixed down switch 51h ensures the limiting purpose of the maximum opening of the peeling clamp 50, so as to facilitate the subsequent peeling process.
4. Axial displacement helix angle adjustment assembly:
the axial displacement helix angle adjusting assembly achieves the aim of adjusting the axial displacement helix angle of the stripper when the cable is stripped, thereby ensuring the control function of the axial movement speed of the cable when the cable is stripped and achieving the maximization of stripping efficiency. Specifically, referring to fig. 21-23, the axial displacement helix angle adjustment assembly includes a blind hole 53b concavely provided in the groove cavity of the V-shaped holding plate 52q of the lower clamp seat 53, so that the function of adjusting the swing angle of the edge of the tooth-shaped guide rib 53d at the guide blade 53c is achieved by the effective cooperation between the square plate-shaped fixed guide blade 53c and the cavity of the blind hole 53b as shown in fig. 23. On the one hand, the matched blind hole 53b is concavely arranged at the groove cavity of the V-shaped holding plate 52q, namely the V-shaped holding surface, so that the purpose of effectively accommodating the guide blade 53c with a certain thickness can be achieved, and the guide blade 53c can not influence the axial movement of the cable. On the other hand, although the guide blade 53c is recessed in the mating blind hole 53b, the tooth-shaped guide rib 53d may protrude from the groove cavity surface of the V-shaped holding plate 52q, so that the cutting edge of the tooth-shaped guide rib 53d may be used to generate a cutting function with respect to the cable insulation cover. In actual operation, as shown in fig. 21-22, the present invention may employ the first adjusting screw 53e to cooperate with the first through counter bore 53g to form a positioning shaft, and employ the second adjusting screw 53f to cooperate with the second through counter bore 53h having an arc hole shape to ensure the adjusted fixing function of the guiding blade 53 c. Corresponding adjusting screws can be hidden in each through counter bore so as to avoid the phenomenon that the protruding parts of the adjusting screws interfere with the action of the cable.
5. Skin guiding device:
The skin guiding device 52w is shown in fig. 1-4, and has a horn mouth shape with a large opening facing upwards, and a connecting vertical plate is arranged at the small-caliber end of the skin guiding device 52w so as to form a fastening fit with a preset assembly hole at the cutter 56, so that stable assembly of the skin guiding device 52w is realized. The function of the skin guiding means 52w is to guide the insulating skin in a spiral shape at the position cut by the cutter 56. When the cutter 56 cuts the cable insulation, the spiral insulation is guided out of the practical working range of the invention by the guiding device 52w shown in fig. 1-4, and then naturally falls under the action of gravity, so as to avoid hard interference of the hard insulation with the normal action of the invention as the cutting process proceeds.
6. Equipotential shrapnel:
The equipotential spring piece 53a is disposed for gradually removing the cable insulation cover and exposing the cable core when the cutter 56 peels off, and at this time, the equipotential spring piece 53a can act to contact the cable core due to its elastic restoring force, and connect the high voltage current at the cable core with the circuit board of the robot to form the equipotential operation effect. The equipotential spring piece 53a may be in a shape of a C-shaped spring piece with a bow back facing upwards as shown in fig. 4, and when in use, one end is fixedly connected in a concave hole groove at the notch of the V-shaped holding plate 52q as shown in fig. 4, and the other end is pressed to generate elastic pressing action along the groove direction of the concave hole groove, and returns to the original state when releasing the pressure. The bow back of the equipotential spring piece 53a should protrude from the groove surface of the V-shaped holding plate 52q for matching with the cable, and is based on the fact that the cable core can be contacted; of course, the specific protruding height of the bow back can be adjusted as required in the field, and will not be described here again.
To facilitate a further understanding of the present invention, a specific workflow of the invention is presented herein as follows:
And (3) a cable cohesion process:
When the cable is required to be peeled, the clamp opening adjusting assembly is operated at first: the operator rotates the opening adjusting knob 51k according to the cable type to be peeled, so as to drive the sensing portion 51n to generate an up-and-down floating motion until the indication arrow 51e at the back of the sensing portion 51n at the observation hole 51c can point to the scale 51d corresponding to the current cable type as shown in fig. 11. Then, the opening and closing driving motor 55 starts to act and drives the bidirectional screw rod 54 to rotate, so that the upper clamp seat 52 and the lower clamp seat 53 of the peeling clamp 50 act oppositely under the action of the threads of the bidirectional screw rod 54 until the V-shaped holding plate 52q at the upper clamp seat 52 and the V-shaped holding plate 52q at the lower clamp seat 53 hold the cable oppositely. When the horizontal pulling tongue 50b at the upper clamp seat 52 touches the sensing end of the sensing part 51n at the preset height on the frame 51, the opening and closing driving motor 55 stops moving, and the cable is stably held by the peeling clamp 50. Of course, when the opening-closing driving motor 55 rotates reversely to drive the peeling clamp 50 to open, the lower travel switch 51h fixed in the groove cavity of the lower right-angle V-shaped groove 51g by the pre-bolts responds, and waits for the horizontal pulling tongue 50b at the lower clamp seat 53 to move downwards and touch the switch end of the lower travel switch 51h, so as to stop the opening-closing driving motor 55, and avoid unnecessary overlarge opening of the peeling clamp 50.
The cable stripping process comprises the following steps:
Before the cable embracing procedure, an operator can determine the thickness of the cable insulation cover and the cutting angle of the cable according to the current cable type, so that the feeding angle of the cutter 56 can be adjusted through the feeding angle adjusting assembly in advance in a suitable manner.
The pre-zero reference correction of the cable stripping process may be synchronized before the cable is stably held by the stripping fixture 50. When being specifically applied to the invention, the operation steps are as follows:
1) Zero reference correction: before the cable is reliably held by the V-shaped holding plate 52q, the cutter depth adjusting knob 52h can be manually rotated in advance, so that the rotating sleeve 52g is driven to act, and the cutter depth adjusting bolt 52f is driven to rise in a follow-up mode. Along with the rotation and upward movement of the knife depth adjusting bolt 52f, firstly the top end surface of the radial protrusion 52l at the position of the depth adjusting bolt is gradually pressed at the lower plate surface of the reference positioning plate 52o, and then the reference positioning plate 52o and even the zero reference sliding plate 52a are driven to generate synchronous upward movement until the zero reference sliding plate 52a is tightly clamped between the radial protrusion 52l and the knife depth adjusting screw seat 52d, at this time, the position state of the peeling clamp 50 is as shown in fig. 9, and the knife tip of the knife 56 is at the same level with the lower end point of the outer circle of the zero reference bearing at this time.
2) And (3) changing positions: in the process of the V-shaped clasping plate 52q clamping the cable, the zero reference bearing, i.e., the reference portion 52k, comes into gradual contact with the cable insulation cover, and the zero reference bearing moves upward under the compression of the cable insulation cover. Because of the presence of the compression spring, i.e., the resilient compression damper 52e, and the zero position reference slide 52a and the depth of blade adjustment slide 52b being forced into a unitary structure by the radial projection 52l of the depth of blade adjustment bolt 52f, the knife 56 at the depth of blade adjustment slide 52b will move up along with the compression spring being forced by the zero position reference bearing at the zero position reference slide 52a, thereby completing the change-positioning step. In the process of changing, the tip of the cutter 56 is always in a state of being in direct contact with the cable insulation cover, as shown in fig. 9;
3) Absolute feed adjustment: after the change-position step is completed, the cutter depth adjusting knob 52h is screwed to drive the cutter depth adjusting bolt 52f to perform a downward motion, so that the radial protrusion 52l moves downward to release the clamping of the reference positioning plate 52 o. At this time, the knife depth adjusting slider 52b integrated with the reference positioning plate 52o moves downward by the elastic restoring force of the compression spring, and the zero reference slider 52a equipped with the zero reference bearing is kept stationary due to the mating relationship with the guide rail of the knife depth adjusting slider 52b and the propping action of the cable insulation cover. Because the limiting slot hole 52m at the rotating sleeve 52g and the limiting protrusion 52n at the knife depth adjusting screw form axial sliding fit capable of transmitting torque, and meanwhile, the elastic power of the compression spring exists, the knife depth adjusting knob 52h can be rotated in place at one time, and then the knife 56 at the knife depth adjusting slide block 52b slowly cuts into the cable insulation skin until reaching the designated cutting depth by means of the releasing performance of the compression spring, as shown in fig. 10.
In the above steps, the model of the cable to be stripped can be predicted, so that the insulation skin depth of the current cable can be known naturally, and the extending action is stopped when the tip of the cutter 56 just can extend to the depth of completely stripping the insulation skin of the cable and starting to expose the cable core by controlling the rotation cycle number of the cutter depth adjusting knob 52 h. Then, the invention is operated to act along the axial direction of the cable, thus realizing the purpose of continuously stripping the insulating sheath of a certain section of cable with high efficiency.
