Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
Referring to fig. 1-5, the embodiment of the invention provides a numerical control machine tool for processing a broken line rope groove, which comprises a frame 5, a cutting assembly 3, a control assembly and a profiling assembly 4.
The frame 5 is provided with a main shaft 1 driving part and a feed driving part, wherein the main shaft 1 driving part is used for driving the main shaft 1 of the numerical control machine tool to rotate, and in the machining process, the main shaft 1 is used for being connected with a workpiece to be machined so as to generate main motion in the cutting process. The feed driving part is used for driving the cutting assembly 3 to generate feed, retreat and move. The control assembly is connected to the spindle 1 drive and the feed drive to control the rotation of the spindle 1 and the movement of the cutting assembly 3. Specifically, the main shaft 1 driving part comprises a servo motor, the feed driving part comprises a servo motor, and the profile driving part comprises a servo motor.
In this embodiment, the cutting assembly 3 includes a tool holder 31, a slider 32, and a base 33.
The base 33 is slidably engaged with a guide rail on the frame 5. The tool holder 31 and the sliding part 32 are both connected to the base 33, so that the base 33 can drive the tool holder 31 and the sliding part 32 to move, thereby realizing the cutting motion in the cutting process. The tool rest 31 is used for mounting a tool, interference is generated between the tool and a reel to be processed, and relative motion is generated between the reel to be processed and the tool, so that the material on the reel to be processed is cut off, and a rope groove is processed. The blade holder 31 is connected to a base 33, and the base 33 is connected to the slider 32, so that the slider 32 can move the blade holder 31 by moving the base 33.
During the processing of the rope grooves of the reel, the numerical control machine tool is enough to generate the rope grooves under the combined action of the main shaft 1 driving part and the feeding driving part. And the broken line inflection section on the rope groove is realized by the following modes:
referring to fig. 2 and 3, the profile assembly 4 includes a profile driving member, a profile rotating shaft 41, a profile block 42, and a sensor. The profile component 4 is connected with the base 33, so that the base 33 can drive the profile component 4 to move together, and the whole profile component 4 can always keep being matched with the tool rest 31.
The contour block 42 has a contour 421 thereon. The profile of the profiling part 421 is used to correspond to the shape of the rope groove to be processed, and the profiling part 421 is used to apply a pushing force to the sliding part 32, so that the sliding part 32 moves under the action of the pushing force and drives the base 33 and the tool rest 31 to move together, thereby changing the motion track formed by the surface forming motion of the tool in the cutting process, and processing the broken line rope groove.
The axial direction of the copying rotating shaft 41 is used for keeping consistent with the axial direction of the reel to be processed. The profile modeling block 42 is of an annular structure, the profile modeling block 42 is sleeved outside the profile modeling rotating shaft 41, the profile modeling block 42 is connected with the profile modeling rotating shaft 41 through a key, and the profile modeling block 42 can be allowed to move along the axial direction of the profile modeling rotating shaft 41. Specifically, a key groove is formed in the profiling rotating shaft 41, and the profiling block 42 is connected with the profiling rotating shaft 41 through a flat key, so that torque can be transmitted between the profiling rotating shaft 41 and the profiling block 42.
The profiling driving piece is connected with the profiling rotating shaft 41 and is used for driving the profiling rotating shaft 41 to rotate.
The sensor sets up on contour block 42, and the sensor is used for detecting contour block 42's angle information to transfer the angle information of contour block 42 to control assembly, control assembly and contour driving spare link to each other, control contour driving spare's turned angle, thereby control contour block 42 rotates, make the relative angle between contour block 42 and the reel of treating to process can keep invariable, thereby make the broken line inflection section on the grooving take place on the specific circumference position of reel.
In particular, in the present embodiment, the sensor is configured as an angular displacement sensor, which may be used to detect angular information of the contour block 42. The control assembly is selected from a siemens 828 ac servo control system which can be used to control movement in three directions and thus can be used to control the spindle 1 drive, feed drive and profile drive.
A contour block 42 is rotatably coupled to the base 33, the contour block 42 being configured to: can translate with the base 33, i.e.: when the base 33 moves along the axial direction of the winding drum and rope grooves on the winding drum are processed one by one, the contour block 42 moves together with the base 33; during the process of machining the single rope groove, the profile block 42 rotates around the profile rotating shaft 41 relative to the base 33, so that the sliding piece 32 can generate relative displacement relative to the surface of the profile block 42, and the profile parameters of the profile block 42 are mapped to the movement of the cutter.
The profile modeling block 42 is provided with a profile modeling portion 421, specifically, the profile modeling portion 421 is a groove-shaped structure annularly arranged on the profile modeling block 42, and the shape of the profile modeling portion 421 is used for corresponding to the shape of a rope groove of a winding drum to be processed. The slider 32 is placed with one end in the groove-like structure formed by the profile 421. Specifically, the correspondence in this embodiment means that during the turning process, the copying block 42 and the spool to be processed rotate simultaneously, the shape of the copying portion 421 and the shape of the spool rope groove to be processed have a matching relationship, and the matching relationship is related to the ratio between the angular velocity of the copying block 42 and the angular velocity of the spool to be processed.
For example, in this embodiment, the profile block 42 rotates at twice the angular velocity of the drum rotation, i.e., one revolution of the drum and two revolutions of the profile block 42. The rope grooves on the reel to be processed are double-fold rope grooves, namely, on the basis of the annular rope grooves, the inflection of two fold lines occurs. The profile 421 of the profile block 42 is also in the form of an annular groove, and the profile 421 has an inflection of a folding line. Through the structure, when the relative motion between the cutter and the winding drum is a whole circle, the profile modeling part 421 and the sliding part 32 relatively move by two circles, so that the sliding part 32 experiences two inflections under the action of the side thrust of the profile modeling part 421, the cutter is driven to slide by the two inflections, two broken line segments appear on the winding drum to be processed, and finally, a double-broken line groove is obtained through processing.
Through the above principle, those skilled in the art can specifically design the profile parameters of the profiling part 421 according to the specific parameters of the required broken line rope groove based on the matching relationship of the angular velocity between the profiling block 42 and the winding drum. For example: two segments of broken lines can be arranged on the copying part 421, and the angular velocity of the winding drum is equal to that of the copying block 42, so that when the copying block 42 rotates for one circle, the winding drum rotates for one circle, and a rope groove with two segments of broken lines can be processed on the winding drum.
The profiling portion 421 acts to apply a pushing force to the base 33, and as the processing proceeds, the action rule of the pushing force corresponds to the shape of the rope groove of the drum. Therefore, according to this principle, the shape of the profiling portion 421 can be variously changed, not limited to the embodiment.
Since the profile portion 421 needs to be designed and processed according to the shape of the rope groove to be processed, the manufacturing cost of the profile portion 421 is higher than that of the slider 32. In order to save cost, the profile 42 is made of a material with a higher hardness than the sliding member 32, so that the profile 42 is prevented from being worn. Specifically, the sliding member 32 is provided as a pin, and the groove surface of the profiling portion 421 is nitrided to improve the hardness and wear resistance of the groove surface.
Referring to fig. 2, 4 and 5, in order to facilitate quick replacement of the sliding member 32 when the sliding member 32 is worn, a mounting hole 331 is formed in the base 33, and the cutting assembly 3 further includes a sliding mounting seat 332, wherein the sliding mounting seat 332 is detachably mounted in the mounting hole 331. The slider 32 is connected to the slide mount 332. In particular, the removable connection between the sliding mount 332 and the base 33 is achieved by: the slide mount 332 is provided with a first screw hole 334, and the base 33 is provided with a second screw hole 3321 fitted to the first screw hole 334. Namely: when the sliding mount 332 is positioned in the mounting hole 331, the position of the first threaded hole 334 corresponds to the position of the second threaded hole 3321. The removable connection between the sliding mount 332 and the base 33 may be achieved by bolts or screws.
In order to further reduce wear between the profile portion 421 and the slider 32, rolling friction is provided between the slider 32 and the profile portion 421. Specifically, the sliding member 32 is coupled to the sliding mount 332 through a bearing, so that when the sliding member 32 moves relative to the profile portion 421, the sliding member 32 can rotate, thereby reducing the friction between the sliding member 32 and the profile portion 421.
Further, the cutting assembly 3 further comprises a cover plate 333, when the sliding member 32 is mounted in the sliding mount 332 through a bearing and the sliding mount 332 is mounted in the mounting hole 331, the cover plate 333 is located above the mounting hole 331 and connected to the base 33, so that the cover plate 333 can cover the mounting hole 331, and this design can prevent dust from entering the sliding mount 332 during operation, thereby preventing the dust from affecting the life of the bearing.
The invention also provides a processing method for processing the winding drum broken line rope groove, which is based on the numerical control machine tool and comprises the following steps:
installing a winding drum to be processed on a main shaft 1, and starting the numerical control machine tool;
during the process of cutting the reel to be processed by the cutting assembly 3, the profiling assembly 4 applies a thrust force to the sliding piece 32, and the sliding piece 32 drives the tool rest 31 to reciprocate in the axial direction of the workpiece, so that a broken line rope groove is formed on the reel.
The working principle of the numerical control machine tool for processing the broken line rope groove provided by the invention is as follows:
in operation, the control assembly controls the rotation of the main shaft 1 driving member, the feed driving member and the profile driving member. The main shaft 1 and the workpiece are driven by the driving drive to rotate, so that a main motion in the cutting process is generated, the base 33 is driven to move by the feeding drive, and the tool rest 31, the sliding part 32 and the contour block 42 are driven by the base 33 to move together, so that a feeding motion, a retracting motion and a moving motion in the cutting process are generated. The profile driving piece drives the profile block 42 to rotate, so that the profile block 42 and the sliding piece 32 generate relative movement, the profile block 42 generates thrust on the sliding piece 32, and the tool rest 31 is driven to move along with the thrust, so that the movement track of the tool is changed, and a broken line section on a rope groove is machined.
The numerical control machine tool for processing the broken line rope groove has the advantages that:
on the basis of numerical control, the track change is realized through the contour block 42, so that the advantage of high-efficiency machining of the numerical control machine tool can be kept, and the defect of high cost caused by large impact and high abrasion due to repeated forward and reverse rotation of the motor can be avoided;
the track change is realized through the profile modeling block 42, the structural rigidity is good, the bearing capacity is large, a motor in the profile modeling driving piece only needs to rotate in a single direction, and the abrasion and the impact on the profile modeling driving piece are small;
the abrasion is mainly concentrated at the profiling block 42 and the sliding part 32, and the sliding part 32 is connected by adopting a bearing, so that the friction force is reduced;
the slide 32 is removably attached to facilitate replacement after significant wear of the slide 32 has occurred.
Example 2
The embodiment of the invention provides a numerical control machine tool for machining a broken line rope groove, which is different from the numerical control machine tool in the embodiment 1 in that: in the embodiment 1, a sensor and a profile modeling driving piece are arranged and connected with a control component through the sensor, and the control component controls the profile modeling driving piece to achieve the purposes of ensuring the relative angle between the profile modeling piece and the main shaft 1 and ensuring that the fold line bending section on the rope groove is generated on a specific circumferential angle; in the present embodiment, the above-mentioned functions are implemented by:
in this embodiment, the numerical control machine comprises a transmission assembly (not shown in the figures) for connecting the driving member of the main shaft 1 with the copying rotating shaft 41. When the driving part 1 drives the workpiece to rotate, the driving part drives the profiling rotating shaft 41 to rotate through the transmission component. Further, the angular velocity of the copying rotating shaft 41 is N times the angular velocity of the main shaft 1, and N is an integer. Namely: the main shaft 1 rotates one circle, and the profiling rotating shaft 41 rotates N circles. The tool must also be located at a corresponding circumferential position on the spindle 1 when the slider 32 slides onto the bend of the cam, thereby ensuring that the fold bend of the rope groove occurs at a specific circumferential position on the drum.
Specifically, the transmission assembly can be set as a gear transmission assembly, a sprocket chain transmission assembly, or the like, as long as the purpose of driving the profiling rotating shaft 41 to rotate through the driving part of the main shaft 1 can be achieved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
