Description

Technical Field

[0001] The invention relates to the technical field of precision parts processing, in particular to a parts processing method, a fixture and a manufacturing method thereof. Background Art

[0002] Precision cylindrical workpieces (see Figure 1 ), with a diameter of only 3-5mm. The parts require high precision, have threads on the surface, and a groove needs to be processed on the end face, which is often processed using wire cutting technology. During the processing, it needs to be fixed with a cylindrical surface and supported by the bottom. Due to the small size of the parts, it is difficult to clamp them using some general fixtures, and it is difficult to ensure that the supporting surface is fully supported. Once the parts are tilted, the tolerance size cannot meet the requirements and the operating error is large. If a special fixture is used, the manufacturing cost is high and the applicability to parts with different structures is low. At the same time, for precision parts, if the clamping force is too large, it is easy to cause damage to the thread on the surface of the parts; if the clamping force is small, the parts are easily affected by the cutting force during the wire cutting process and shake, thereby affecting the processing accuracy. Therefore, there is an urgent need for a parts processing method, a fixture and a manufacturing method thereof that can improve the stability of part clamping and reduce the cost of the fixture. Summary of the invention

[0003] In view of the above problems in the prior art, the present application provides a part processing method, a fixture and a manufacturing method thereof, which can improve the stability of part clamping and reduce costs.

[0004] A first aspect of the present invention provides a method for processing a part, wherein the part has an external threaded portion, comprising: preparing a fixture, wherein the fixture comprises: a main body, wherein the main body is in the shape of a plate, and a surface thereof has a first plane and a second plane which are perpendicular to a thickness direction and parallel to each other; a clamping hole, wherein the clamping hole is a through circular hole, and one end of the clamping hole is located on the first plane; a deformation seam, wherein the deformation seam is arranged on the main body, connecting the first plane and the second plane, wherein one end of the deformation seam is located in the main body, and the other end extends through the clamping hole to the surface of the main body, and separates the two parts of the main body corresponding to the two sides of the deformation seam into a first part and a second part; a fastening hole, wherein the fastening hole penetrates the first part and then extends into the second part, and an internal thread is arranged in the part of the fastening hole in the second part; a fastener, wherein the fastening hole The fastener is a bolt, which can be screwed into the fastening hole and can drive the first part and the second part to be close to each other; a spring hole, which is arranged on the main body and has a diameter larger than the clamping hole, and the two ends of the spring hole are respectively located on the first plane and the second plane, and one end of the deformation seam is connected to the spring hole; a support plate, which is attached to the second plane to cover the other end of the clamping hole; a clamping part, wherein the part includes a first part with a first external threaded portion, the first external threaded portion of the first part is placed in the clamping hole, and one end of the first part is abutted against the support plate, in this state, the first external threaded portion is clamped by the clamping hole with a predetermined clamping force; the end of the first part exposed from the clamping hole is processed.

[0005] From the above, by making the first plane parallel to the second plane, the main body can be conveniently clamped and fixed using a vise. By making the deformation seam pass through the clamping hole and dividing the main body into the first part and the second part, after the part is placed in the clamping hole, the first part and the second part can be driven close together by the fastening mechanism, so that the parts of the clamping hole on both sides of the deformation seam can be close together to clamp and fix the part. Since the clamping hole is a circular hole, after the outer peripheral surface of the part is clamped and fixed, a surface contact is formed between the clamping hole and the outer peripheral surface of the part. In this way, the contact area between the part and the clamping hole can be increased, thereby improving the stability and firmness of the part clamping and fixing.

[0006] In addition, by arranging the clamping holes and the deformation seams on the main body, the structure of the clamp can be made simpler, and the clamp can be obtained by processing the main body, thereby reducing the processing difficulty and further reducing the cost of the clamp.

[0007] In addition, the clamping force can be controlled by means of bolts to avoid damage to the external threaded portion.

[0008] As a possible implementation, the part also includes a second part, the second part has a second external threaded portion, and the diameter of the second external threaded portion is larger than that of the first external threaded portion. The processing method also includes: increasing the size of the clamping hole by processing; placing the second external threaded portion of the second part in the clamping hole with increased size, and making one end of the second part abut against the support plate, in this state, the clamping hole with increased size clamps the second external threaded portion; processing the end of the second part exposed from the clamping hole.

[0009] The present invention processes parts of larger sizes by increasing the size of the clamping hole without replacing the clamp, and has the advantages of simple equipment structure, low cost, etc.

[0010] To achieve the above-mentioned purpose, the second aspect of the present application provides a clamp, including: a main body, the surface of which has a first plane and a second plane that are parallel to each other; a clamping hole, which is a circular hole, and one end of the clamping hole is located on the first plane; a deformation joint, which is arranged on the main body and connects the first plane and the second plane, one end of the deformation joint is located in the main body, and the other end passes through the clamping hole and extends to the surface of the main body, separating the two parts of the main body corresponding to the two sides of the deformation joint into a first part and a second part; a fastening mechanism, which is arranged on the main body to drive the first part and the second part to approach each other.

[0011] From the above, by making the first plane parallel to the second plane, the main body can be conveniently clamped and fixed using a vise. By making the deformation seam pass through the clamping hole and dividing the main body into the first part and the second part, after the part is placed in the clamping hole, the first part and the second part can be driven close together by the fastening mechanism, so that the parts of the clamping hole on both sides of the deformation seam can be close together to clamp and fix the part. Since the clamping hole is a circular hole, after the outer peripheral surface of the part is clamped and fixed, a surface contact is formed between the clamping hole and the outer peripheral surface of the part. In this way, the contact area between the part and the clamping hole can be increased, thereby improving the stability and firmness of the part clamping and fixing.

[0012] In addition, by arranging the clamping holes and the deformation seams on the main body, the structure of the clamp can be made simpler, and the clamp can be obtained by processing the main body, thereby reducing the processing difficulty and further reducing the cost of the clamp.

[0013] As a possible implementation manner of the second aspect, it further includes: a spring hole, wherein the spring hole is arranged on the main body, two ends of the spring hole are respectively located on the first plane and the second plane, and one end of the deformation seam is connected to the spring hole.

[0014] As described above, by providing a spring hole at one end of the deformation joint, the first part and the second part can be easily deformed at the connection position, so that the fastening mechanism drives the first part and the second part to approach each other to clamp and fix the parts.

[0015] As a possible implementation manner of the second aspect, the deformation seam is rectangular and extends along a center line of the main body.

[0016] From the above, by making the deformation seam rectangular and extending along the center line of the main body, the first part and the second part can be made symmetrical and equal, so that when the first part and the second part are driven close together by the fastening mechanism, the deformation of the first part and the second part is the same, thereby improving the firmness and stability of the clamping hole clamping the parts.

[0017] As a possible implementation manner of the second aspect, the spring hole is a circular hole, and when viewed along the extension direction of the deformation joint, the axis of the spring hole coincides with the deformation joint.

[0018] From above, along the extension direction of the deformation joint, by making the axis of the spring hole coincide with the deformation joint, the deformation of the first part and the second part at the connection position can be made more uniform when the first part and the second part are close, thereby improving the firmness and stability of the clamping hole clamping parts.

[0019] As a possible implementation manner of the second aspect, viewed along the extension direction of the deformation joint, the axis of the clamping hole coincides with the deformation joint.

[0020] From the above, along the extension direction of the deformation joint, by making the axis of the clamping hole coincide with the deformation joint, the two parts of the clamping hole on the first part and the second part can be made more uniform. Therefore, when the clamping hole is clamping and fixing the part, the contact area between the two sides of the deformation joint and the part can be made uniform, thereby improving the stability of the clamping and fixing of the part.

[0021] As a possible implementation manner of the second aspect, the fastening mechanism includes: a fastener, which is passed through the first part, one end of the fastener abuts against the first part, and the other end is threadedly connected to the second part.

[0022] As described above, the first part and the second part can be driven to approach each other by a single fastener, so that the clamp can be operated conveniently. Meanwhile, the structure of the clamp can be simplified and the cost of the clamp can be reduced.

[0023] As a possible implementation manner of the second aspect, the fastener is located between the clamping hole and the other end of the deformation joint.

[0024] As described above, by positioning the fastener between the clamping hole and the other end of the deformation joint, the fastener can be kept away from the position where the first part and the second part are connected, so that the first part and the second part can be driven closer by the fastener. Thus, the difficulty of operating the clamp can be reduced.

[0025] As a possible implementation of the second aspect, the clamping hole is a through hole, and the other end of the clamping hole is located on the second plane; the clamp also includes: a support plate, which is attached to the second plane to cover the other end of the clamping hole.

[0026] From the above, by attaching a support plate to the second plane to cover the other end of the clamping hole, the support plate can provide support for the end of the part after the part is placed in the clamping hole. Therefore, when the part is clamped and processed by wire cutting, the support plate can be used to fix the axial direction of the part, thereby improving the stability of the part.

[0027] The third aspect of the present application provides a method for making a clamp, including: selecting a plate with two parallel surfaces as a main body, and the two parallel surfaces as a first plane and a second plane; processing a circular hole near one end of the main body to form a clamping hole, and one end of the clamping hole is located on the first plane; processing a deformation seam on the main body, and the deformation seam connects the first plane and the second plane, and one end of the deformation seam is located in the main body, and the other end passes through the clamping hole and extends to the surface of the main body, and the two parts of the main body corresponding to the two sides of the deformation seam are separated into a first part and a second part; processing a fastening hole on the main body, and the fastening hole penetrates the first part and then extends into the second part; processing an internal thread in the part of the fastening hole in the second part; selecting a bolt compatible with the internal thread of the fastening hole, and the bolt can pass through the fastening hole in the first part and then be threadedly connected with the fastening hole in the second part, so as to drive the first part and the second part to approach each other.

[0028] As described above, by setting the clamping hole and the deformation seam on the main body, the structure of the clamp can be made simpler, and the clamp can be obtained by processing the main body, thereby reducing the processing difficulty and further reducing the cost of the clamp.

[0029] In addition, by making the first plane parallel to the second plane, it is convenient to use a vise to clamp and fix the main body. By making the deformation seam pass through the clamping hole and dividing the main body into the first part and the second part, after the part is placed in the clamping hole, the first part and the second part can be driven close together by the fastening mechanism, so that the parts of the clamping hole on both sides of the deformation seam can be brought close together to clamp and fix the part. Since the clamping hole is a circular hole, after the outer peripheral surface of the part is clamped and fixed, a surface contact is formed between the clamping hole and the outer peripheral surface of the part. In this way, the contact area between the part and the clamping hole can be increased, thereby improving the stability and firmness of the part clamping and fixing.

[0030] As a possible implementation method of the third aspect, it also includes: processing a circular through hole on the main body at a position corresponding to one end of the deformation seam to form a spring hole, so that the deformation seam is connected to the spring hole; selecting a plate as a support plate, the size of the support plate is adapted to the second plane, the clamping hole is a through hole, the other end of the clamping hole is located on the second plane, and the support plate is attached to the second plane to cover the other end of the clamping hole.

[0031] From the above, by setting a spring hole at one end of the deformation joint, the first part and the second part can be easily deformed at the connection position, so that the fastening mechanism drives the first part and the second part to approach each other to clamp and fix the part. By attaching a support plate to the second plane to cover the other end of the clamping hole, the support plate can provide support for the end of the part after the part is placed in the clamping hole. Therefore, when the part is clamped and processed by wire cutting, the support plate can be used to fix the axial direction of the part, thereby improving the stability of the part.

[0046] References to "one embodiment" or "an embodiment" in this specification mean that a particular feature, structure, or characteristic described in conjunction with the embodiment is included in at least one embodiment of the present invention. Therefore, the phrases "in one embodiment" or "in an embodiment" appearing in various places in this specification do not necessarily refer to the same embodiment, but may refer to the same embodiment. In addition, in one or more embodiments, the particular features, structures, or characteristics can be combined in any appropriate manner, as would be apparent to one of ordinary skill in the art from this disclosure.

[0047] The present application provides a clamp 10, which can clamp and fix a cylindrical part 20, so as to process the part 20. Below, in conjunction with the accompanying drawings, a possible embodiment of the clamp 10 in the present application is exemplarily described.

[0048] like Figure 2-Figure 6 As shown, the clamp 10 in the present application includes a main body 100, a clamping hole 130, a deformation joint 150 and a fastening mechanism. The surface of the main body 100 has a parallel first plane 110 and a second plane 120, and the first plane 110 and the second plane 120 are perpendicular to the plate thickness direction (thickness direction) of the main body 100. The clamping hole 130 is a through circular hole, and one end of the clamping hole 130 is located on the first plane 110. The deformation joint 150 is arranged on the main body 100, penetrates the main body 100 in the plate thickness direction, connects the first plane 110 and the second plane 120, one end of the deformation joint 150 is located in the main body 100, and the other end passes through the clamping hole 130 and extends to the surface of the main body 100, separating the two parts of the main body 100 corresponding to the two sides of the deformation joint 150 into a first part 160 and a second part 170. The fastening mechanism is arranged on the main body 100, driving the first part 160 and the second part 170 to approach.

[0049] From the above, by making the first plane 110 and the second plane 120 parallel, the main body 100 can be conveniently clamped and fixed using the vise 30. By making the deformation seam 150 pass through the clamping hole 130 and dividing the main body 100 into the first part 160 and the second part 170, after the part 20 is placed in the clamping hole 130, the first part 160 and the second part 170 can be driven close together by the fastening mechanism, so that the parts of the clamping hole 130 on both sides of the deformation seam 150 can be brought close together to clamp and fix the part 20. Since the clamping hole 130 is a circular hole, after the outer peripheral surface of the part 20 is clamped and fixed, a surface contact is formed between the clamping hole 130 and the outer peripheral surface of the part 20. In this way, the contact area between the part 20 and the clamping hole 130 can be increased, thereby improving the stability and firmness of the clamping and fixing of the part 20.

[0050] In addition, by setting the clamping hole 130 and the deformation gap 150 on the main body 100, the structure of the clamp 10 can be made simpler, and the clamp 10 can be obtained by processing the main body 100. Therefore, the processing difficulty can be reduced, and the cost of the clamp 10 can be reduced.

[0051] In some embodiments, the diameter of the clamping hole 130 is adapted to the diameter of the part 20. Specifically, the diameter of the clamping hole 130 may be equal to the diameter of the part 20, or slightly larger than the diameter of the part 20. Thus, the contact area between the clamping hole 130 and the part 20 when clamping and fixing the part 20 can be increased, thereby improving the stability and firmness of the clamping.

[0052] In some embodiments, a plurality of clamping holes 130 may be provided along the deformation seam 150 , and the plurality of clamping holes 130 may have diameters of different sizes. Thus, the clamp 10 may be adapted to parts 20 of different sizes, thereby increasing the adaptability range of the clamp 10 .

[0053] like Figure 3 , Figure 6 As shown, in some embodiments, the clamp 10 further includes a spring hole 140, which is disposed on the main body 100, with both ends of the spring hole 140 respectively located on the first plane 110 and the second plane 120, and one end of the deformation slit 150 is connected to the spring hole 140. Thus, by arranging the spring hole 140 at one end of the deformation slit 150, it is convenient for the first part 160 and the second part 170 to deform at the connection position, so that the fastening mechanism drives the first part 160 and the second part 170 to approach to clamp and fix the part 20.

[0054] like Figure 3 , Figure 6 As shown, in some embodiments, the deformation seam 150 is rectangular and extends along the center line L of the main body 100. Therefore, by making the deformation seam 150 rectangular and extending along the center line L of the main body 100, the first part 160 and the second part 170 can be symmetrically equal, so that when the first part 160 and the second part 170 are driven close to each other by the fastening mechanism, the first part 160 and the second part 170 are deformed in the same manner, thereby improving the firmness and stability of the clamping hole 130 clamping the part 20.

[0055] like Figure 3 , Figure 6 As shown, in some embodiments, the spring hole 140 is a circular hole, and the axis of the spring hole 140 coincides with the deformation slit 150 when viewed along the extension direction of the deformation slit 150. Therefore, when viewed along the extension direction of the deformation slit 150, by making the axis of the spring hole 140 coincide with the deformation slit 150, the deformation of the first part 160 and the second part 170 at the connection position can be made more uniform when the first part 160 and the second part 170 are close to each other, thereby improving the firmness and stability of the clamping hole 130 clamping the part 20.

[0056] like Figure 3 , Figure 6 As shown; in some embodiments, when viewed along the extension direction of the deformation joint 150, the axis of the clamping hole 130 coincides with the deformation joint 150. Thus, when viewed along the extension direction of the deformation joint 150, the axis of the clamping hole 130 coincides with the deformation joint 150, so that the two parts of the clamping hole 130 on the first part 160 and the second part 170 can be made more uniform. Thus, when the clamping hole 130 clamps and fixes the part 20, the contact area between the two sides of the deformation joint 150 and the part 20 can be made more uniform, so that the stability of clamping and fixing the part 20 can be improved.

[0057] like Figure 2-Figure 4As shown, in some embodiments, the fastening mechanism includes: a fastener 200, the fastener 200 is inserted into the first part 160, one end of the fastener 200 is in contact with the first part 160, and the other end is threadedly connected with the second part 170. Thus, the first part 160 and the second part 170 can be driven close to each other by the fastener 200, so that the clamp 10 can be operated conveniently. At the same time, the structure of the clamp 10 can be simplified and the cost of the clamp 10 can be reduced.

[0058] like Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, in some embodiments, the fastening mechanism also includes a fastening hole 180 arranged on the main body 100, and the fastening hole 180 penetrates the first part 160 and extends into the second part 170. The fastening hole 180 is provided with an internal thread in the part of the second part 170. The fastener 200 passes through the first part 160 through the fastening hole 180 and is threadedly connected with the fastening hole 180 in the second part 170.

[0059] In this embodiment, the clamping hole 130 is located between the fastening hole 180 (fastener) and the spring hole 140 .

[0060] like Figure 3 As shown, in some embodiments, the fastener 200 is located between the clamping hole 130 and the other end of the deformation joint 150. Thus, by making the fastener 200 located between the clamping hole 130 and the other end of the deformation joint 150, the fastener 200 can be kept away from the position where the first part 160 and the second part 170 are connected, so that the first part 160 and the second part 170 are driven to approach each other by the fastener 200. Thus, the difficulty of operating the clamp 10 can be reduced.

[0061] like Figure 2 , Figure 4 As shown, in some embodiments, the fastener 200 is a bolt. Therefore, by using a bolt as the fastener 200, the processing steps of the fastener 200 can be reduced, thereby reducing the processing cost of the clamp 10.

[0062] like Figure 3 As shown, in some embodiments, the fastening hole 180 is a through hole passing through the first part 160 and the second part 170. The bolt passes through the first part 160 and the second part 170 through the fastening hole 180 and is threadedly connected with the nut, and the first part 160 and the second part 170 are driven closer together by the bolt and the nut.

[0063] In some embodiments, the clamping hole 130 is a through hole, and the other end of the clamping hole 130 is located on the second plane 120. The fixture 10 further includes a support plate 300, which is attached to the second plane 120 and blocks the other end of the clamping hole 130. Thus, by attaching the support plate 300 to the second plane 120 to block the other end of the clamping hole 130, after the part 20 is placed in the clamping hole 130, the support plate 300 can provide support for the end of the part 20. Thus, when the part 20 is clamped and processed by wire cutting, the support plate 300 can be used to fix the axial direction of the part 20, thereby improving the stability of the part 20.

[0064] In some embodiments, the clamping hole 130 is a blind hole, and after the part 20 is inserted into the clamping hole 130, the end of the part 20 can be supported and positioned by the bottom of the clamping hole 130. In this way, not only the stability of the part 20 can be improved, but also the number of components of the fixture 10 can be reduced, thereby simplifying the structure of the fixture 10 and reducing the cost of the fixture 10.

[0065] The above content is an exemplary description of a possible embodiment of the clamp 10. Next, in conjunction with the accompanying drawings, the specific structure of the clamp 10 is described in detail in a specific embodiment.

[0066] Figure 1 2 is a schematic diagram of the side projection structure of the part 20 in this application. Figure 1 As shown, the part 20 that needs to be processed in this application is a cylindrical part 20, the diameter of the part 20 is 5 mm, the outer peripheral surface of the part 20 is provided with a thread, one end of the part 20 is a supporting surface 21, and the other end is a processing surface 22. A rectangular through groove needs to be processed by a wire cutting machine.

Figure 2-Figure 6 As shown, the clamp 10 in the present application includes a main body 100, a fastener 200 and a support plate 300. The main body 100 can clamp and fix the outer peripheral surface of the part 20 under the drive of the fastener 200, and the support plate 300 can abut against the support surface 21 at one end of the part 20 to position the part 20 in the axial direction, thereby improving the firmness and stability of the part 20.

[0068] like Figure 2-Figure 6 As shown, the main body 100 is a rectangular plate-like component having a parallel first plane 110 and a second plane 120, and the first plane 110 and the second plane 120 are the two surfaces with the largest area of ​​the main body 100. The main body 100 is provided with a circular through-hole-shaped clamping hole 130 and a spring hole 140, which penetrate the main body 100 in the plate thickness direction of the main body 100, and the two ends of the clamping hole 130 and the spring hole 140 are respectively located on the first plane 110 and the second plane 120. The clamping hole 130 and the spring hole 140 are arranged at positions corresponding to the center line L of the main body 100, and the axes of the clamping hole 130 and the spring hole 140 are perpendicularly intersected with the center line L of the main body 100. The spring hole 140 is located near the middle position of the main body 100, and the clamping hole 130 is located near one end of the main body 100.

[0069] The main body 100 is also provided with a rectangular deformation joint 150, which connects the first plane 110 and the second plane 120, extends from one end of the main body 100 along the center line L of the main body 100, passes through the clamping hole 130 and extends to the spring hole 140, and is connected with one side of the spring hole 140, so that the main body 100 is formed into a separated first part 160 and a second part 170 on both sides of the deformation joint 150. The diameter of the clamping hole 130 is adapted to the diameter of the part 20, and the diameter of the spring hole 140 is larger than the clamping hole 130, so that the position of the spring hole 140 is deformed more easily, so that the fastener 200 drives the first part 160 and the second part 170 to approach each other, so that the clamping hole clamps and fixes the outer peripheral surface of the part 20.

[0070] The main body 100 is also provided with a fastening hole 180, which penetrates the first part 160 and extends into the second part 170, and the fastening hole 180 is provided with an internal thread in the part of the second part 170. The fastener 200 is a bolt, which can be threadedly connected with the fastening hole 180 in the second part 170 after passing through the first part 160 through the fastening hole 180. Therefore, by screwing the fastener 200 into the fastening hole 180, the first part 160 and the second part 170 can be driven to approach, and then the parts of the clamping hole 130 located on both sides of the deformation joint 150 can be approached, so that the part 20 is clamped and fixed.

[0071] like Figure 2 As shown, the support plate 300 is a rectangular plate-shaped component, and the size of the support plate 300 is the same as that of the first plane 110 and the second plane 120, and can be attached to the second plane 120 to cover and shield the clamping hole 130 at one end of the second plane 120. After the part 20 is placed in the clamping hole 130, the support surface 21 of the part 20 can abut against the support plate 300, so as to axially position the part 20.

[0072] like Figure 2As shown, the present invention also relates to a processing method for processing a part 20 using a clamping mechanism composed of a clamp 10 and a vise 30, wherein the clamp is manufactured and prepared, and the main body 100 and the supporting plate 300 can be placed in the vise 30, so that the first plane 110 and the second plane 120 correspond to the two jaws of the vise 30 respectively, and the main body 100 and the supporting plate 300 are clamped and fixed by the vise 30, and the surface of the supporting plate 300 faces the clamping hole 30. The position where the vise 30 clamps the main body 100 is at the end of the main body 100 away from the deformation seam 150, so as not to affect the deformation of the position of the spring hole 140. After the main body 100 and the supporting plate 300 are fixed, the part is clamped, wherein the external thread part of the part 20 is placed in the clamping hole 130, and the supporting surface 21 of the part 20 is abutted against the supporting plate 300. By rotating the fastener 200, the first portion 160 and the second portion 170 are brought close to each other, and the external thread portion of the part 20 is clamped and fixed in the clamping hole 130. Finally, the processing surface 22 of the end of the part 20 exposed from the clamping hole 130 is processed (eg, a processing cut) using a wire cutting tool.

[0073] In addition, during clamping, in order to avoid damage to the threaded portion, the clamping hole is clamped to the external threaded portion of the part with a predetermined clamping force. As an implementation example, for example, the specified number of turns of tightening of the fastener (bolt) is obtained in advance (for example, different numbers of turns of tightening are set for external threaded portions of different diameters through experiments in advance, and in production, the specified number of turns of tightening is obtained according to the diameter), and the fastener is screwed into the fastening hole according to the specified number of turns of tightening. In the above description, the installation of the support plate by means of a vise is only an example, and the support plate can also be installed on the main body 100 by means of bolts or the like.

[0074] The present application also provides a method for manufacturing a clamp 10. The specific steps of the method for manufacturing the clamp 10 in the present application are described in detail below in conjunction with the accompanying drawings.

[0075] Figure 7 FIG. 9 is a flow chart of a fixture manufacturing method 90 in the present application. Figure 7 As shown, the specific steps of the fixture manufacturing method 90 in the present application include:

[0076] Step S901, obtain the subject 100.

[0078] Step S903 , processing the clamping hole 130 .

[0079] In step S903, a circular through-hole-shaped clamping hole 130 is processed on the first plane 110 / the second plane 120 of the main body 100, so that the spring hole 140 is located at the midline position of the main body 100 and close to one end area of ​​the main body 100. The diameter of the clamping hole 130 is the same as the diameter of the part 20, or slightly larger than the diameter of the part 20.

[0080] Step S905 , processing the spring hole 140 .

[0081] In step S905, a circular through-hole-shaped spring hole 140 is processed on the first plane 110 / second plane 120 of the main body 100, so that the spring hole 140 is located at the midline position of the main body 100, and the spring hole 140 is located near the middle in the length direction of the main body 100. The diameter of the spring hole 140 can be processed to be larger, larger than the diameter of the clamping hole, and specifically can be, for example, half the width of the first plane 110 / second plane 120 of the main body 100.

[0082] Step S907 , processing the deformation joint 150 .

[0083] In step S907, a rectangular deformation seam 150 is processed on the main body 100, and the end of the main body 100 close to the clamping hole 130 is cut along the center line L to form a rectangular deformation seam 150. The deformation seam 150 connects the first plane 110 and the second plane 120. The deformation seam 150 extends from one end of the main body 100 through the clamping hole 130 to the spring hole 140 and is connected to the spring hole 140. The two parts of the main body 100 corresponding to the two sides of the deformation seam 150 are separated into a first part 160 and a second part 170 through the deformation seam 150, so that half of the clamping hole 130 is located in the first part 160, and the other half is located in the second part 170.

[0084] Step S909 , processing the fastening hole 180 .

[0085] In step S909, a circular fastening hole 180 is processed on the side of the body 100. The fastening hole 180 penetrates the first portion 160 and extends into the second portion 170 to form a blind hole in the second portion 170. An internal thread is processed in the fastening hole 180 in the second portion 170.

[0086] Step S911, obtaining the fastener 200.

[0087] In step S911, a suitable bolt is selected as the fastener 200 so that one end of the fastener 200 can pass through the fastening hole 180 to be threadedly connected to the first part 160 and the second part 170, and the other end of the fastener 200 abuts against the first part 160, so that the first part 160 and the second part 170 can be driven closer by rotating the fastener 200.

[0088] Step S913: Acquire the supporting plate 300.

[0089] In step S913 , a plate of suitable thickness is selected and processed into a rectangular shape so that the size of the plate is the same as the first plane 110 / the second plane 120 , thereby forming a supporting plate 300 .

[0090] As described above, both the plate and the bolt are very easy to obtain materials. The clamp 10 can be made by using the above-mentioned clamp manufacturing method 90, and the clamp 10 can be made by simple and common materials through simple processing methods such as punching and cutting. In this way, the processing difficulty of the clamp 10 can be reduced, and the cost of the clamp can be reduced.

[0091] The above-mentioned parts processing method may include a method for manufacturing a clamp. In addition, since the clamp 10 has a simple structure and low manufacturing difficulty, it can be applied to parts with different diameters by simply modifying the different hole diameters of the clamp. That is, in the processing method, a step of changing (for example, increasing by processing) the size of the clamping hole 130 can be included to process other parts with external threaded parts having larger diameters.

[0092] As described above, the present invention is particularly suitable for processing precision cylindrical parts with a diameter of 3-5 mm (external threaded portion).
