DETAILED DESCRIPTION

[0018] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0019] The existing technology has technical problems of low processing efficiency and poor through-hole coaxiality when processing through-holes of brittle materials.

[0020] To this end, the present application provides a double-sided punching fixture, wherein the double-sided punching fixture clamps a part to be processed, and under the clamping of the double-sided punching fixture, a first through hole in the part to be processed is processed by double-sided punching, and the part to be processed is provided with a first processing surface and a second processing surface on both sides along a first direction, respectively. The double-sided punching fixture includes: a connecting component, wherein a second through hole is provided in the connecting component along the first direction, wherein two ends of the second through hole along the first direction respectively have a first processing position and a second processing position, a part to be processed is located in the second through hole, and a first processing surface of the part to be processed corresponds to the first processing position, and a second processing surface of the part to be processed corresponds to the second processing position; A clamping assembly, wherein the clamping assembly includes two or more clamping members, the clamping members are connected to the connecting assembly, the clamping members have a first end, the first end of the clamping member is located in the second through hole, and a first clamping space is formed between the first ends of the clamping members, and the part to be processed is located in the first clamping space; A first driving member is connected to the clamping assembly, and is used to drive the clamping assembly to move and clamp or release the workpiece to be processed in the first clamping space.

[0021] Example 1: In the prior art, brittle materials generally refer to ceramics, glass, and crystal materials, etc. When performing through-hole processing on brittle materials, if a drill is used to drill through the workpiece in one go, and the brittle material in this application has high hardness and low toughness, then when subjected to external force, it is difficult for the back port of the through-hole to absorb energy through plastic deformation. Therefore, there will be problems with the formed back port of the through-hole having poor molding quality or even cracking.

[0022] In order to solve the above technical problems, the current method is to punch holes on both sides of the workpiece to form the first hole and the second hole respectively, and then connect the first hole and the second hole to form a through hole. However, this through hole processing method usually requires secondary clamping to process the first hole and the second hole respectively. Since two clampings are required, there will be a coaxiality difference between the first hole and the second hole after the two clampings, and the two clampings will also affect the processing efficiency.

[0023] Please refer to the attached Figure 1 To the attached Figure 4 As shown, the first direction X of the present application refers to the width direction of the double-sided punching fixture 20, that is, the direction from front to back of the double-sided punching fixture 20 or the direction from back to front of the double-sided punching fixture 20. In the present application, the second connecting plate 130 is arranged in front of the first connecting plate 120, and the first connecting plate 120 is arranged in the back relative to the second connecting plate 130. The second direction Y of the present application refers to the length direction of the clamping rod 220. In the present application, the clamping rod 220 is a long strip structure, and the clamping rod 220 has a first end 221 and a second end 222. Furthermore, the length direction of the clamping rod 220 refers to the direction from the first end 221 to the second end 222 of the clamping rod 220 or the direction from the second end 222 to the first end 221 of the clamping rod 220.

[0024] Attachment Figure 1 This is a structural diagram of the part 10 to be processed. Figure 1 As shown, the part to be processed 10 needs to be processed by the double-sided punching fixture of this application. The part to be processed 10 is provided with a second center line 15 along the first direction X. The second center line 15 passes through the part to be processed 10, and the remaining components in the part to be processed 10 are arranged around the second center line 15. The second center line 15 is a virtual line set in the part to be processed 10. The second center line 15 is further set to further explain the relationship between the part to be processed 10 and the double-sided punching fixture 20. The part to be processed 10 of the present application is provided with a first processing surface 12 and a second processing surface 13 on both sides along the first direction X. The first processing surface 12 and the second processing surface 13 refer to the processing surfaces of the first through hole 11 in the part to be processed 10. The part to be processed 10 also includes a first through hole 11. The first through hole 11 is provided in the part to be processed 10 along the first direction X. In the part to be processed 10, the first through hole 11 extends from the first processing surface 12 to the second processing surface 13 or from the second processing surface 13 to the first processing surface 12. The first through hole 11 in the part to be processed 10 is bidirectionally processed by the first processing surface 12 and the second processing surface 13 respectively. The part 10 to be processed is made of a brittle material, which generally refers to ceramics, glass, silicon, crystal materials, etc. In the prior art, when processing brittle materials, if the part 10 to be processed is processed by unidirectional drilling, due to the high hardness and low toughness of the brittle material, when subjected to external force, the back end of the first through hole 11 is difficult to absorb energy through plastic deformation. Therefore, there will be problems such as poor molding quality or even cracking of the back end of the first through hole 11 formed. When the drill bit approaches the bottom of the first through hole 22, due to the internal stress concentration of the material, it is easy to cause cracking. Furthermore, an alignment edge 14 is also provided on the part 10 to be processed. The alignment edge 14 on the part 10 to be processed is used to achieve alignment with the position of the part 10 to be processed, thereby preventing the position of the first through hole 11 from shifting during drilling.

[0025] In one embodiment, the workpiece 10 to be processed is a cylindrical structure or a regular polygonal structure. Attachment Figure 2 This is a structural diagram of the double-sided punching fixture 20 of the present application. Figure 2As shown, the double-sided punching fixture 20 of the present application is a fixture for clamping the part to be processed 10. The double-sided punching fixture 20 of the present application is used simultaneously with the double-sided drilling equipment. When used, the double-sided punching fixture 20 is installed on the drilling equipment, and the first through hole 11 in the part to be processed 10 is processed by a double-sided punching method at both ends of the part to be processed 10 along the first direction X. The drill bit is coaxially arranged on both sides of the part to be processed 10 to ensure the coaxiality of the first through hole 11 in the part to be processed 10. At the same time, double drill bit processing can further improve the drilling processing efficiency.

[0026] Please refer to the attached Figure 2 As shown, the double-sided punching fixture 20 of the present application includes a connecting component 100, which is a connecting member between the double-sided punching fixture 20 and the drilling equipment, and realizes the bearing of the clamping component and the first driving member 300. The connecting component 100 is provided with a second through hole 110 along the first direction X. The second through hole 110 is used to accommodate the part 10 to be processed. At the same time, the second through hole 110 has a first processing position and a second processing position at both ends along the first direction X. Figure 2 The first processing position and the second processing position are not shown. The first processing surface 12 of the part 10 to be processed corresponds to the first processing position, and the second processing surface 13 of the part 10 to be processed corresponds to the second processing position. The first processing position is used to set the first drill bit, and the second processing position is used to set the second drill bit. The first drill bit and the second drill bit are always coaxially set in the drilling equipment, and the coaxially set first drill bit and second drill bit are derived from the adjustment of the drilling equipment. Therefore, under the setting of the double-sided punching fixture 20, the first drill bit and the second drill bit simultaneously drill the first through hole 11 on the same axis from both sides, which improves the processing efficiency of the first through hole 11 while avoiding the problem of poor molding quality of the back port of the first through hole 11 or even cracking when the first through hole 11 is drilled through at one time. And because the first drill bit and the second drill bit are coaxially arranged at the same time, the coaxiality of the first through hole 11 can be guaranteed. When drilling the first through hole 11, the first drill bit can be withdrawn before the second drill bit before the first through hole 11 is drilled through to avoid collision between the first drill bit and the second drill bit.

[0027] Among them, the connecting assembly 100 includes a first connecting plate 120 and a second connecting plate 130, and the first connecting plate 120 and the second connecting plate 130 are arranged in sequence along the first direction X. Furthermore, the first connecting plate 120 and the second connecting plate 130 are connected in a rotating manner, and the second through hole 110 passes through the first connecting plate 120 and the second connecting plate 130 one by one. The first connecting plate 120 is used to realize connection with the drilling equipment, so that the relative position between the double-sided punching fixture 20 and the first drill bit and the second drill bit can be adjusted through the drilling equipment. The second connecting plate 130 is used to carry the clamping assembly and the first driving member 300, thereby indirectly realizing the carrying of the part 10 to be processed.

[0028] In one embodiment, the second connecting plate 130 and the second through hole 110 are both circular structures, and the second connecting plate 130 is disposed around the second through hole 110 .

[0029] The connecting assembly 100 includes a second driving member 140, which is driven and connected to the second connecting plate 130 to drive the second connecting plate 130 to rotate around the first center line 261, thereby further adjusting the position of the part to be processed 10 in the circumferential direction. During the specific adjustment, a dial indicator or a micrometer is used to offset the alignment edge 14, and the position of the part to be processed 10 in the circumferential direction is adjusted by detecting the parallelism of the alignment edge 14 to ensure the accuracy of the position of the first through hole on the part to be processed 10.

[0030] The connecting assembly 100 also includes a third limiting member 150, which is disposed between the first connecting plate 120 and the second connecting plate 130 to limit the rotation angle of the second connecting plate 130 about the first centerline 261, thereby defining a rotation path between the second connecting plate 130 and the first connecting plate 120 and preventing separation between the first connecting plate 120 and the second connecting plate 130. Furthermore, three or more third limiting members 150 are disposed about the first rotation center, and each third limiting member 150 is uniformly spaced from the first centerline 261. The third limiting member 150 includes a third limiting slot 151 and a second connecting rod 152, each of which is an arc-shaped structure and disposed on the second connecting plate 130. The second connecting rod 152 is connected to the first connecting plate 120 and passes through the third limiting slot 151 along the first direction X, thereby abutting against the second connecting plate 130 to prevent separation between the first connecting plate 120 and the second connecting plate 130. The second driving member 140 is connected to the second connecting plate 130, and the second driving member 140 includes a driving rod and a driving block. The driving block is connected to the second connecting plate 130, and the driving rod and the driving block are transmission-connected to drive the second connecting plate 130 to rotate around the first center line 261, and the second connecting rod 152 simultaneously forms relative motion in the third limiting groove 151.

[0031] Please refer to the attached Figure 2As shown, the double-sided punching fixture 20 of the present application also includes a clamping assembly and a first driving member 300. The clamping assembly is used to clamp the workpiece 10 to be processed. The clamping assembly includes more than two clamping members 200. The clamping members 200 are connected to the connecting assembly 100. The clamping members 200 are elongated structures. The clamping members 200 include a first end 221 and a second end 222 along their length. The first end 221 of the clamping member 200 is located in the second through hole 110, and a first clamping space 210 is formed between the first ends 221 of the clamping members 200. That is, the area between the first ends 221 of the clamping members 200 forms the first clamping space 210. The workpiece 10 to be processed is located in the first clamping space 210 to form the clamping assembly to clamp the workpiece 10 to be processed. The first driving member 300 is connected to the clamping assembly and is used to drive the clamping assembly to move and clamp or release the workpiece 10 to be processed in the first clamping space 210.

[0032] The clamping assembly also includes a first trajectory 260. The first trajectory 260 is provided to further explain the scope of the first clamping space 210 formed by the rotation of the clamping member 200, thereby further enabling the clamping of parts 10 of varying sizes. The first trajectory 260 defines a first centerline 261 along the first direction X. During clamping, the first centerline 261 within the first trajectory 260 coincides with the second centerline 15 of the part 10 to achieve adaptive clamping between the clamping assembly and the part 10, and to maintain accurate positioning between the part 10 and the double-sided punching fixture 20 during the machining process. The second end 222 of the clamping member 200 coincides with the first trajectory line 260. The clamping member 200 is rotatably connected to the connecting assembly 100 under the drive of the first driving member 300. The second end 222 of each clamping member 200 is synchronously deflected in the second through hole 110 to change the size of the first trajectory line 260. After the first trajectory line 260 is changed, it can simultaneously clamp or release the part to be processed 10. Since the size of the first trajectory line 260 is variable, the specifications of the part to be processed 10 that can be clamped can also be changed at the same time to adapt to the clamping of parts to be processed 10 of different specifications.

[0033] In one embodiment, the first trajectory line 260 is circular, and the workpiece 10 to be processed is also circular. The first trajectory line 260 is polygonal, and the workpiece 10 to be processed is also polygonal.

The clamping member 200 includes a first end 221 and a second end 222 along its length direction. The first end 221 of the clamping rod 220 coincides with the first end 221 of the clamping member 200, and one side of the second end 222 of the clamping rod 220 coincides with a portion of the second connecting plate 130, and the first end 221 of the clamping rod 220 is located in the second through hole 110.

The clamping rod 220 is rotatably connected to the connecting assembly 100 via the rotating portion 230 .

[0036] In one embodiment, the rotating portion 230 includes a rotating rod and a rotating hole. The rotating hole is located on the second connecting plate 130 . The rotating rod is disposed on the clamping rod 220 . The rotating rod extends into the rotating hole along the first direction X and forms a rotating connection with the rotating hole.

[0037] The clamping member 200 also includes a clamping portion 240. The first end 221 of the clamping member 240 is provided with the clamping portion 240. The clamping portion 240 is arranged on the first trajectory line 260. A second clamping space 250 is provided in the clamping portion 240. The second clamping space 250 is provided with an opening toward the first clamping space 210 to realize the communication between the first clamping space 210 and the second clamping space 250. The part to be processed 10 is partially provided in the second clamping space 250, and the clamping portion 240 forms a clamping of the part to be processed 10 in the first direction X, and each clamping member 200 can form a clamping of the part to be processed 10 in the circumferential direction under the drive of the first driving member 300, thereby further forming a multi-directional clamping of the part to be processed 10.
