Description

  The present invention relates to a processing auxiliary device suitable for fine adjustment of a processing amount in a processing operation in which a processing surface disposed on the base surface is used as a processing surface and a required processing operation is performed on a workpiece (workpiece). It is.

  Electric tools called routers or trimmers, which are mainly used for woodworking, are popular tools in the field of so-called do-it-yourself such as do-it-yourself. Conventionally, when machining is performed using this type of electric tool, most of the work depends on manual work. As a result, the machining accuracy depends on the skill level of the person who performs the work. Therefore, it is difficult to manufacture a plurality of processed products with a certain accuracy. In addition, for example, it is not easy to perform precise processing of 1 mm or less in cutting using wood as a workpiece, and it is particularly difficult to obtain a square material obtained by cutting a small piece of wood into an accurate shape.

  What has been found by the investigation of the prior art is a processing apparatus disclosed in Japanese Patent Application Laid-Open No. 2005-59217, which mainly aims at processing an edge portion of an edge of a siding material. The invention of the same number is placed on the table with the workpiece to be punched in contact with the ruler means at one edge and with the edge to be processed in contact with the positioning stopper means. The workpiece is pressed and fixed to the table from above by the clamping means. In this state, the position of the edge of the workpiece abutted against the positioning stopper means and the rotary blade of the rotary tool means The outer reference surface is matched, and the rotary tool is moved along the edge of the workpiece, and the edge of the workpiece is punched at a predetermined width and depth by the rotary blade. Thus, it can be easily achieved in a stable state, and the workability can be improved.

  In other words, the present invention performs predetermined processing with the workpiece pressed and fixed on the table by the clamping means. The technical feature on the woodwork is that the movement of the workpiece (workpiece) is a ruler. To the extent that it can be seen in using the clamping means for fixing the workpiece. As clamp means, two L-shaped clamp levers, a first connection link for connecting them in a tiltable manner via a second support pin, and a tip end portion of the L-shaped portion at the lower end of the clamp lever A clamp lever supported to be tiltable via a third support pin at a position lower than the first support pin; a fourth support pin at a corner of the substantially L-shaped portion at the lower end; and a first support pin of the one clamp lever A second connecting link that is connected to be tilted in a slanting manner, and a clamp screw that is screwed into a substantially horizontal end portion of each of the two clamp levers. Yes. However, this mechanism is not particularly useful for precisely processing woodwork products.

Another object of the present invention is to make it possible to quickly and precisely fine-tune the workpiece processing amount by a simple operation using only one lever.

  In order to solve the above-mentioned problems, the present invention provides a fixing means for engaging a side of a base in a processing operation in which a processing surface arranged on the upper surface of the base is used as a processing surface and a required processing is performed on the work. A fixing member fixed to the base by the operation member, an operation side guide member attached to the fixing member so as to be movable in the left-right direction of the fixing member, and a fine member provided on the fixing member so as to be able to move forward and backward with respect to the processing portion An adjustment guide member, and a fine movement device that finely adjusts the distance of the fine adjustment guide member to the processing portion, wherein the fine adjustment device is slidably press-contacted with the operation side guide member and the fine adjustment guide member. It has a slope structure in which the front-rear direction component is set shorter than the left-right direction component, and a mechanism for moving the operation side guide member in the left-right direction in order to move the fine adjustment guide member in the front-rear direction. Structure In which it took measures that. As a fixing member to be fixed to the base, a pair of front and rear fixing members is provided, one of which is disposed on the processing portion side, the other is disposed on the operation portion side, and is composed of members below the operation side guide member. Used as a base material for providing a fine adjustment mechanism for the amount of workpiece movement.

  The apparatus of the present invention is intended for cutting and the like in which the upper surface of the base is used as a processing surface and a required processing operation is performed on a workpiece by a processing unit arranged there. The machining operation here refers to an operation in which the electric tool is used as a stationary type. Therefore, the processing unit in the present invention means a mechanical device that performs a processing operation, and includes a power tool described later or a processing machine using the power tool. In order to obtain a stationary type, the base is attached to a work table or the like, and an electric tool is attached to the base, but the apparatus of the present invention can use any table as a work table. The base can be attached to the work table by any known means.

  As the above-mentioned electric tool used for the processing work, a tool called a router or a trimmer mainly used for the woodworking work is representative. However, various grinders, wood carvers, drills and other tools can also be used. Furthermore, these power tools are attached to a position and a state suitable for work on a processing surface on the base, with the base or other parts as attachment targets. In the embodiment described later, the lower surface of the base of the electric power tool is an attachment part of the electric power tool, and the vertical movement member is provided so as to be movable up and down via the attachment part installed on the lower surface of the base. The cutting tool is configured to project from the upper surface of the base by means of a vertically moving member, and this is only an example.

  The processing auxiliary device according to the present invention includes a fixing member fixed to a base by fixing means that engages with a side of the base, and an operation-side guide attached to the fixing member so as to be movable in the left-right direction of the fixing member. And a fine adjustment guide member provided on the fixed member so as to be capable of moving forward and backward relative to the processing portion, and a fine adjustment device for finely adjusting the distance of the fine adjustment guide member to the processing portion. The fixing member is a member for mounting the processing assisting device of the present invention on the base, the operation side guide member is moved with respect to the fixing member, and the fine adjustment guide member is operated with respect to the operation side guide member.

  The base is disposed in parallel with the fixing member fixed to the base and has a processing part side guide member on the side of the processing part arranged on the processing surface, and the processing part side guide member includes the fixing member and the processing part side guide member. It is desirable to have a configuration in which means for processing with a workpiece sandwiched between them is disposed. Thereby, it is possible to perform a processing operation such as a precise cutting process by using the fixing member on the operation unit side and the guide member on the processing unit side in combination.

  Since the present invention is configured and operates as described above, precise processing of a woodworking product is easily performed by the configuration of a fine movement device including a slope in which the longitudinal component is set shorter than the lateral component. There is an effect that can be. In addition, according to the present invention, the fine movement device can be operated by a simple operation using a single lever rotatably supported on the fixed member, and the workpiece processing amount can be finely adjusted quickly, precisely and accurately. It is possible to provide a processing auxiliary device in a possible processing operation.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows an example of a processing assisting device 30 in a processing operation according to the present invention. 10 is a cutting amount adjusting device, 11 is the above-mentioned electric tool, and for example, a router called a router is particularly small. A woodworking power tool called a trimmer is one example. The adjusting device 10 is intended to be used by attaching the power tool 11 as described above, which is handled as a hand-held tool, to the lower surface of the base 12 and installing the base 12 on the work table 13 (see FIG. 2). A special work table 13 is not required, and any table that can withstand a load of about a dozen kilograms is applicable and intended to be able to work safely.

  The base 12 is equipped with the power tool 11 and the processing auxiliary device 30 of the present invention, and can perform cutting or the like on the board surface. The base 12 is preferably made of a lightweight material such as an aluminum plate, has sufficient strength and plane accuracy for various processing operations such as cutting, and is preferably formed in a rectangular plane shape. . The base 12 includes a clamp 14 as a means for installing it on the work table 13. The clamp 14 is sized to receive the side portion of the work table 13, and includes a clamp frame 14 a having a substantially C-shaped cross section and a mounting screw 14 b. The clamp frame 14a itself is firmly attached to the lower surface of the attachment side portion of the base 12, and the attachment screw 14b is attached to the lower frame of the C-shaped clamp frame 14a by screwing.

  A fixed member 15 on the processing part side is detachably attached to one side of the base 12. The fixing member 15 on the processing part side has a substantially L-shaped cross section having a lower plate part 15a placed on the board surface of the base 12 and a side plate part 15b rising from one side thereof (see FIG. 3). . The fixing member 15 on the processed portion side has a dimension that slightly exceeds the length of one side of the base 12. In the substantially central part of the fixing member 15 on the processed part side, a suction port 15c is provided by cutting out a portion corresponding to an L-shaped corner into a hemispherical shape so as to eliminate chips generated by cutting by suction, and A suction hood 16 is attached to the outside of the suction port 15c, and a suction duct 17 is connected to the connection port 16a. The fixing member 15 on the processing portion side needs to be attached to the base 12 so that it can be easily attached and detached and can withstand the processing work, as in the processing auxiliary device 30 of the present invention. The fixing member 15 on the side is provided.

  The processed portion side fixing member 15 has engagement pieces 18 and 19 having substantially C-shaped cross sections at both ends in order to engage with the left and right side portions of the base 12. One engagement piece 18 only needs to have an engageable C-shaped cross-sectional shape, while the other engagement piece 19 has a C-shaped cross-sectional shape and is provided with a fixing means. ing. In the illustrated fixing means, the lock member 19a is attached to the inside of a C-shaped cross-section so that the distal end thereof moves inward and outward by a support shaft 19b on the proximal end side, and between the two end portions. The lever 20 is provided on the outer side so as to be rotatable around the screw shaft, and the intermediate portion of the lock member 19a is pressurized inward at the tip of the screw shaft 20a (FIGS. 5 and 6). And FIG. 7). Therefore, by rotating the lever 20 to the right, the side surface of the base 12 can be tightened via both the engaging pieces 18 and 19 and the lock member 19a, and the fixing member 15 can be fixed to the base 12, and The fixed position can be arbitrarily determined.

  The cutting amount adjusting device 10 shown as an example in the illustrated embodiment is for attaching the electric tool 11 to the lower surface of the base 12, and in order to enable attachment of the electric tool 11 of each company, a tool attaching method by fitting. Is taking. That is, a blade placement portion 12a for placing the blade 11a of the electric tool 11 is provided at a position away from the clamp 14 of the base 12 (see FIGS. 3 and 5), and this blade placement portion 12a. An attachment portion 21 for the electric power tool 11 is provided so that the blade 11a is disposed on the blade 11a (see FIGS. 6 and 7). The attachment portion 21 is attached to the back surface of the base 12 at the upper end portion, and the back portion is attached to the front surface of the clamp 14, and is firmly attached by bolting.

  The attachment portion 21 of the electric tool 11 is provided with a vertical movement mechanism of the electric tool 11. For this reason, the attachment portion 21 is formed with a guide rail 22 composed of vertical dovetails. A vertically moving member 24 having ant legs 23 to be engaged is mounted (see FIG. 8). The attachment portion 21 is formed with a female screw portion 24a into which a male screw portion 25a of a stopper 25 disposed outside is partly engaged with a part of the vertical movement member 24. Therefore, a part of the vertical movement member 24 is A long hole 21a is formed on the inner surface of the mounting portion in the sliding range over the vertical movement range of the male screw portion 25a.

  The vertical movement member 24 is formed in a circular cross-sectional shape so that the cylindrical body of the electric power tool 11 is fitted and attached by insertion, and the circular ends 24b and 24b can be tightened by bolts 24c. It has the structure. However, although it can be said that the sizes of the electric tools 11 of each company are almost the same, they are not the same. Therefore, in the example shown in the figure, the adapter 26 is used together so that the electric tools 11 of the entire company can be used. The adapter 26 shown in FIG. 4 has a plurality of types having different wall thicknesses (reference numeral 26 for convenience of explanation) in order to fill the difference in diameter between the cylindrical body having a different size and the circular cross-sectional shape. -1 and 26-2). The adapter 26 has a cylindrical shape so as to be almost in contact with the cylindrical body portion of the electric power tool 11 and is a non-cylindrical shape to enhance the attachment / detachment flexibility. The electric power tool 11 is attached to the vertical movement member 24 or the adapter 26 by friction fitting. However, since the external force applied to the blade 11a is from the side, the holding force is not sufficient. Absent.

  In the illustrated example, a cam lever mechanism that accurately adjusts the protruding amount of the blade 11a by lever operation is applied as the vertical movement mechanism of the blade 11a by the vertical movement member 24. For this reason, the vertical movement mechanism includes a support member 27 installed in the lower portion of the base 12, a lever 28 pivotally supported at a base end portion in a shaft hole formed in the support member 27, and the rotation of the lever 28. A cam 29 that is mounted integrally with the shaft 28 a and disposed between the support member 27 and the previous mounting portion 21, and a vertical movement member 24 that is engaged with the arc-shaped cam groove 29 a of the cam 29. And a combination 24d. Therefore, the arc-shaped cam groove 29a is provided so that the blade 11a protrudes from the bottom surface of the base plate to the base surface by a protrusion amount corresponding to the work as the lever 28 rotates several tens of degrees. (See FIG. 9).

  In the illustrated cam lever mechanism, the blade 11a is in the raised position when the engaging element 24d is near the base of the arc-shaped cam groove 29a, and the lowered position in the opposite position. Whereas the lever 28 is linear, the arc-shaped cam groove 29a almost overlaps the start point and end point on the lever 28, and the halfway point between the fulcrum and end point corresponds to the operation direction of pushing the lever 28. It is arranged to take a concave shape. For this reason, when the lever 28 is pulled and the blade 11a is protruded, it rises slightly earlier on the operation start side and rises later on the end side, so that the operability is improved and the protrusion amount is subtle. Adjustment is possible.

  Furthermore, the processing auxiliary device 30 of the present invention will be described. The processing auxiliary device 30 of the present invention also includes an auxiliary device 32 that is attached to the fixing member 40 on the operation unit side. However, it can also be used together with the processing unit side auxiliary device 31 that is used by being attached to the processing unit side fixing member 15 described above (see FIGS. 1 and 11 etc.). The processing unit side auxiliary device 31 includes a processing unit side movable guide member 34 attached to the processing unit side fixing member 15 at a portion of the long hole 33 provided in the processing unit side fixing member 15 at the front in the feeding direction. Similarly, it has a fixed guide member 36 attached to the processing part side fixing member 15 through the long hole 35 at the rear in the feed direction. Members 37 and 38 are provided (see FIG. 5). Reference numeral 34 a denotes a finger hook, which is used for pushing and pulling the processed portion side movable guide member 34.

  One parallel movement member 37 is slidably in contact with the plate surface of the side plate portion 15b of the processing portion side fixing member 15, and is provided so as to be movable in the left-right direction within the range of the left-right long hole 37b opened in itself. The other parallel movement member 38 has a female screw portion 38b provided at a position overlapping with the long hole 37b, and a set screw 39 is inserted from the long hole 33 formed in the plate surface of the side plate portion 15b. It is the structure fixed so that position adjustment is possible by screwing and engaging with the internal thread member 38b. The slopes 37a and 38a have an inclination of 10: 1, and a movement of 10 mm in the left-right direction becomes a movement of 1.0 mm in the front-rear direction. Therefore, the amount of movement in the front-rear direction is relative to the amount of movement in the left-right direction. Therefore, the cutting amount can be adjusted with a precision that is substantially ten times higher. In order to set the numerical value, a scale S is provided on one of the slopes 37a and 38a, and an index A indicating the scale is provided on the other.

  The other parallel movement member 36 is slidable on the plate surface of the side plate portion 15b and is provided to support the workpiece after cutting. Accordingly, the front surface of the parallel movement member 36 is attached so as to occupy a position coinciding with the tangent on the cutting side in the rotating surface of the blade 11a. The same set screw 39 as described above is inserted through the long hole 35 formed in the plate surface of the side plate portion 15b, and screwed into the female screw member 38b provided at the back of the hole portion 36b provided at a position overlapping with the elongated hole 35. By doing so, the position can be adjusted. The portions 36c and 37c in the vicinity of the blade 11a of the pair of parallel movement members 37 and 38 are cut into a quadrant, thereby preventing a conflict and providing a space for removing chips. A spring 39a is applied to the set screw 39, thereby acting to bring the inclined surfaces of the translation member into contact with each other.

  The auxiliary device 32 that controls the main configuration of the processing auxiliary device 30 of the present invention is used together with the fixing member 40 on the operation unit side. The fixing member 40 is attached to the base 12 with the same configuration as the processing part-side fixing member 15 that is engaged with and attached to the left and right sides of the base 12 in order to use the processing part-side auxiliary device 31. Yes. Therefore, the illustrated fixing member 40 has a substantially L-shaped cross section having a lower plate portion 40a placed on the board surface of the base 12 and a side plate portion 40b rising from one side thereof (FIG. 1, FIG. 2 and 5), the dimension slightly exceeds the length of one side of the base 12.

  The fixing member 40 on the operation unit side has engagement pieces 41 and 42 having a substantially C-shaped cross section at both ends, and the one engagement piece 41 is a C-shape that can be engaged with the side of the base 12. In addition to having a C-shaped cross-sectional shape, the other engagement piece 42 has a fixing means. In the fixing means, the lock member 42a is attached to the inside of a C-shaped cross section so that the distal end portion thereof moves inward and outward by a support shaft 42b on the proximal end side, and the outer side between both end portions is attached. The lever 43 is provided so as to be rotatable around a screw shaft, and an intermediate portion of the lock member 42a can be pressurized inward at the tip of the screw shaft 43a (see FIGS. 1 and 5). Therefore, similarly to the above, by rotating the lever 43, the side surface of the base 12 is fastened together with the engaging piece 41 via the engaging piece 42 and the lock member 42a, and the fixing member 40 on the operating portion side is fixed to the base 12. The fixing position can be arbitrarily determined.

  The auxiliary device 32 is attached at the same through holes 44 and 44 as the operation side guide member 45 attached at the portion of the through holes 44 and 44 in the feed direction (front-rear direction) provided on the side plate portion 40 b of the fixing member 40. Two fine adjustment guide members 46 are provided on the left and right. The operation side guide member 45 and the fine adjustment guide member 46 can be moved in contact with each other on the inclined surfaces 45a, 46a. The operation side guide member 45 is in sliding contact with the plate surface of the side plate portion 40b of the fixing member 40 on the operation portion side. These are provided so as to be movable in the left-right direction within the range of the long holes 45b in the left-right direction opened in itself.

  The fine adjustment guide member 46 has a female screw portion 46 b provided at a position overlapping the through hole 44. Therefore, the set screw 47 can be inserted from the through hole 44 opened in the plate surface of the side plate portion 40b, passed through the long hole 45b opened in the operation side guide member 45, and screwed into the female screw portion 46b. Furthermore, it can be fixed at the adjustment position. The inclined surfaces 45a and 46a have a 10: 1 inclination like the pair of parallel movement members 37 and 38, and a movement of 10 mm in the left-right direction becomes a movement of 1.0 mm in the front-rear direction. Similarly, the amount of movement in the front-rear direction is one-tenth of the amount of movement in the left-right direction, and the cutting amount can be finely adjusted with substantially ten times the accuracy. For this numerical setting, a scale S is provided on one of the slopes 45a and 46a, and an index A indicating the scale is provided on the other.

  Furthermore, the fine adjustment device 50 for the fine adjustment guide member 46 is provided on the fixing member 40 on the operation unit side. The fine movement device 50 includes an arcuate guide groove 40c formed in the side plate portion 40b of the fixing member 40, a vertical linear guide groove 45c formed in the operation side guide member 45, and a center point of the arc. The fine movement lever 48 pivotally supported by the fixing member 40 and an engagement shaft 49 attached to the fine movement lever 48 between the axis of the fine movement lever 48 and the operation portion are provided. It itself engages with the semicircular guide groove 40c and the linear guide groove 45c. Therefore, the rotation operation of the fine adjustment lever 48 is converted into the movement of the operation side guide member 45 in the left-right direction, and the fine adjustment guide member 46 is further moved in the front-rear direction (fine movement) by the component force of the inclined surfaces 45a, 46a. This is a configuration to be converted (see FIG. 6).

  In order to adjust the protruding amount of the blade 11a in the cutting machine configured as described above, first, the body portion of the electric tool 11 is inserted into the vertical movement member 24 from below and attached by fitting. At that time, if the diameter of the body portion of the vertically moving member 24 does not match the diameter of the body portion, a suitable fitting 26 is used to obtain a close fitting, and the bolt 24c is tightened as necessary. In a state where the electric tool 11 is attached to the vertical movement member 24, the vertical movement member 24 is in a position where it is lowered by the load of the electric tool 11, and the engaging element 24d is at the lower end of the arc-shaped cam groove 29a. Therefore, when the lever 28 is rotated clockwise, the engaging element 24d is moved closer to the base of the cam groove 29a, and the electric tool 11 is moved upward, the state shown in FIG. 2 is obtained. Thereby, the blade 11a of the electric tool 11 can be protruded by a desired amount from the upper surface of the base 12. When the desired protrusion is reached, the stopper 25 is operated and fixed.

  According to the processing auxiliary device 30 in the processing operation of the present invention, various cutting processes are possible as follows. The machining example will be described. FIG. 10 shows a state in which the workpiece W is machined by the cutting amount dmm with the blade 11a to form the reference surface. In order to set the cutting amount, on the scale S of the translation member 38, the translation member 37 is moved in the left-right direction until the index A indicates a position corresponding to 10 times from 0 mm to dmm, and the set screw 39 is operated. Then, the movable guide member 34 is fixed at the corresponding position. In FIG. 10, since the index A indicates 30 mm, the cutting amount for the workpiece W is 3 mm, and the difference between the front surface of the fixed guide member 36 and the front surface of the translation member 38 is 3 mm. Accordingly, the reference surface 51 can be formed on the workpiece W by operating the electric power tool 11, feeding the workpiece W along the front surface of the parallel movement member 38, and performing cutting with the blade 11 a. The immediately following reference surface 51 is supported by the front surface of the stationary guide member 36.

  The width of the workpiece W cut by the above processing is L1 (FIG. 11). In order to obtain a precisely machined workpiece W having a width L, it is next necessary to machine the opposite side of the reference surface 51 of the workpiece W. Therefore, the reference surface 51 is used as the auxiliary device of the present invention. 32 is arranged in close contact with the rear surface 46 b of the fine adjustment guide member 46. At that time, the processing member side fixing member 15 side removes the parallel movement members 37 and 38 from the processing unit side fixing member 15, and replaces the detent members 53 and 53 ′ called feather boards with the blade 11 a instead. Two are attached to the left and right (FIG. 12). The detent members 53 and 53 'have a structure in which a large number of elastic teeth 53a are attached so as to have a forward inclination in the feed direction of the workpiece W, and the movement or return of the workpiece W in the direction against the inclination is prevented. This is particularly effective when the amount of machining (machining allowance) is small. The machining allowance that can be absorbed by the elastic deformation of the elastic teeth 53a varies depending on the elasticity of the material, but is assumed to be about 1 to 3 mm. Reference numeral 53b denotes a transparent cover, which is provided on one of the detent members so as to cover between the detent members 53 and 53 '.

  In FIG. 12, since the index A indicates a position shifted from 0 mm to 15 mm of the scale S, the cutting amount d ′ of the workpiece W is 1.5 mm. As shown in FIG. 10, when it is unclear whether the machining allowance is large, a step is provided between the front surface of the fixed guide member 36 and the front surface of the parallel movement member 38. It is not necessary to provide a step on the front surface of the members 53 and 53 ', and the range can be absorbed by the elastic deformation of the elastic teeth 53a. Therefore, in the above setting, the set screws 39 and 47 are operated so that the workpiece W is sandwiched between the detent members 53 and 53 ′ and the auxiliary device 32 of the present invention and fixed under a moderate pressure. . By performing the cutting process in this state, the surface (reference surface 51) cut in the previous process is supported by the rear surface 46b of the fine adjustment guide member 46, and the workpiece W slides. (See FIG. 13).

  In this way, the machining auxiliary device 30 according to the present invention performs precision machining on two parallel surfaces of the workpiece W, and a machining surface 52 parallel to the reference surface 51 can be obtained (see FIG. 14). However, in order to obtain a precisely machined square, it is necessary to repeat the same operation as described above for the remaining two surfaces. As a result of all such processes, it is possible to obtain a square member in which the four surfaces are cut flat and precisely and the corners are precisely cut by 90 degrees. In the field of so-called do-it-yourself, small squares are often required, and in particular, it is difficult for conventional woodworking machinery to precisely cut small squares from any material that is at hand. there were. However, according to the processing assisting device 30 of the present invention, the workpiece W can be precisely machined as described above, and a highly accurate square can be obtained easily and reliably.

  FIG. 15 shows a cross-sectional view of the workpiece W in which a machining surface 52 parallel to the reference surface 51 is formed after the first reference surface 51 is cut by the machining auxiliary device 30 of the present invention. Reference numerals 54 and 55 denote the remaining two processed surfaces. This cutting process is a process performed by the blade 11a longer than the maximum width of the workpiece W, but the types of processes that can be performed by the processing auxiliary device 30 of the present invention are not limited to the above. That is, it is also possible to freely select whether to cut only a part of the workpiece W or to cut over the entire width depending on the protruding amount of the blade 11a. FIG. 16 shows an example thereof, which shows a state in which the decorative portion C is cut at one corner of the workpiece W using the blade 11a having the curved surface 11b (FIG. 16A). The decorative part C can be cut at both corners by exchanging the left and right sides of the workpiece W processed at one corner and sending the workpiece W along the guide surface 46b of the fine adjustment guide member 46 (FIG. 16B).

  If the example of FIG. 16 is considered, it will be understood that various forms of cutting can be performed on the workpiece W by the processing assisting device 30 of the invention, and processing with a high degree of freedom can be performed. Let's go. In the case of machining for cutting the decorative part C or the like only on a part of the work W, most of the work W other than the decorative part C is the same as the original dimensions. Therefore, since the portion immediately after the processing is supported by the front surface of the fixed-side guide member 36, the step for adjusting the cutting amount described with reference to FIG. 10 is unnecessary. The present invention is characterized in that a square material obtained by cutting a small piece of wood into an accurate shape can be easily obtained. Here, “small” means, for example, about 10 × 10 mm square for the cross-sectional shape and about 3 mm in thickness. If it is a strip-shaped plate material, about 3 × 10 mm is intended. When feeding such a small workpiece W, an instrument such as a spatula having a portion that engages with the workpiece W can be used.

  What is shown as the above embodiment is a cutting machine and mainly intended for wood processing, but can also be applied to the processing of materials other than natural wood, or synthetic resin materials, light metal materials, etc. Is self-explanatory. Moreover, the processing auxiliary device 30 of the present invention is not limited to application to cutting machines. That is, the electric tools to which the present invention can be applied are electric tools or various processing machines using the electric tools called routers or trimmers as described above. In addition, various grinders, wood carving machines, drills and other tools can be used. A processing machine that uses an electric tool is assumed to be a tool that changes the power of the tool itself or adds a new one, such as an example where a bit of an electric drill is replaced with a rotating file and used as a sander. Of course, the processing assisting device 30 according to the present invention can be applied to such a processing machine when it is installed as a processing portion on the processing surface to perform the operation.
