[0037] The clamping jig 100 provided by the present application is applied to machining equipment such as a cylindrical grinder and a milling machine, and is used for clamping workpieces such as a bar 200.

[0038] The clamping jig 100 provided by the present application will be described below in conjunction with Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 embodiments of the present application.

[0039] It should be noted that the first direction in the following is the x direction shown in the figure, the second direction in the following is the y direction shown in the figure, and the third direction in the following is the z direction shown in the figure.

[0040] The clamping jig 100 provided by the present application includes a seat body 10, a clamping assembly 20 and an adjusting assembly 30.

[0041] The clamping assembly 20 includes a base 21, a movable member 22, and a clamping member 23. The base 21 has a through hole 211. The movable member 22 is rotatably disposed on the base 21 about the axis of the through hole 211. The movable member 22 has a groove 221 on the side facing the base 21. The distance between the bottom 2213 of the groove 221 and the axis of the through hole 211 gradually decreases along the circumference of the through hole 211. The clamping member 23 is slidably assembled on the base 21 along the radial direction of the through hole 211. One end of the clamping member 23 slidably abuts against the bottom 2213 of the groove 221, and the other end of the clamping member 23 extends to the through hole 211 to clamp the workpiece.

[0042] For example, both the base 21 and the movable part 22 are disc-shaped; however, the base 21 and the movable part 22 can also be other shapes. Figure 4 and Figure 6 As shown, the through hole 211 penetrates the base 21 and the movable member 22 along the first direction x, and the axis of the through hole 211 extends along the first direction x. The movable member 22 extends along... Figure 3 and Figure 6 The direction 'a' shown rotates relative to the base 21. A groove 221 is provided on the surface of the movable member 22 facing the base 21. The opening of the groove 221 is arranged facing the axis of the through hole 211. The bottom 2213 of the groove 221 is located between the surface of the movable member 22 facing the base 21 and the surface of the movable member 22 away from the base 21. The distance between the bottom 2213 of the groove 221 and the axis of the through hole 211 is along... Figure 3 and Figure 6 The direction 'a' shown gradually increases.

[0043] One end of the clamping member 23 abuts against the bottom 2213 of the sink 221. When the movable member 22 moves relative to the base 21 along... Figure 3 and Figure 6 When rotating in direction a as shown, the distance between the bottom 2213 of the groove 221 that abuts against the clamping member 23 and the axis of the through hole 211 gradually decreases, thereby pushing the clamping member 23 to move radially along the through hole 211 until the other end of the clamping member 23 abuts against the outer wall of the bar 200.

[0044] The adjustment component 30 is located between the base 10 and the clamping component 20, and the adjustment component 30 is adapted to adjust the height of the clamping component 20 on the base 10.

[0045] like Figure 2 As shown, the base 10 is adapted to mount the clamping fixture 100 provided in this application on the worktable 300. The adjustment component 30 is connected between the base 10 and the clamping component 20. The portion of the adjustment component 30 between the base 10 and the clamping component 20 has an adjustable dimension in the third direction z, so as to adjust the distance between the bar stock 200 in the clamping component 20 and the base 10, that is, to adjust the height of the bar stock 200 on the base 10.

[0046] The clamping jig 100 provided by the application has the beneficial effects that the clamping jig 100 provided by the application comprises a seat body 10, a clamping assembly 20 and an adjusting assembly 30, the clamping assembly 20 comprises a base body 21, a movable piece 22 and a clamping piece 23, the side of the movable piece 22 facing the base body 21 is provided with a sink groove 221, one end of the clamping piece 23 abuts against the groove bottom 2111 of the sink groove 221, the other end of the clamping piece 23 extends to the inside of the through hole 211 along the radial direction of the through hole 211, since the distance between the groove bottom 2213 of the sink groove 211 and the axis of the through hole 211 gradually decreases along the circumferential direction of the through hole 211, the clamping piece 23 can be driven to move towards the axis of the through hole 211 by rotating the movable piece 22 to clamp the bar 200 in the through hole 211, and the bar 200 can be quickly positioned by abutting the clamping piece 23 against the surface of the bar 200 along the radial direction of the through hole 211, so that the clamping jig 100 provided by the application has higher positioning efficiency and positioning accuracy.

[0047] In some embodiments, as shown in Figure 6 The base body 21 is provided with a stop hole 213, one end of the stop hole 213 communicates with the inner wall of the through hole 211, the other end of the stop hole 213 penetrates the base body 21 along the radial direction of the through hole 211, and the clamping piece 23 is slidably assembled in the stop hole 213, so that the clamping piece 23 can extend along the radial direction of the through hole 211.

[0048] In some embodiments provided by the application, the sink groove 221 comprises a first section 2211 and a second section 2212 arranged along the circumferential direction of the through hole 211, the groove bottom 2213 of the first section 2211 extends along the tangential direction of the through hole 211, the groove bottom 2213 of the second section 2212 has a first position and a second position, the first position is located between the second position and the first section 2211, and the distance between the first position and the axis of the through hole 211 is smaller than the distance between the second position and the axis of the through hole 211.

[0049] As shown in Figure 6 In the second section 2212, the end of the groove bottom 2213 in the second section 2212 away from the first section 2211 has the maximum distance from the axis of the through hole 211, and the end of the groove bottom 2213 in the second section 2212 close to the first section 2211 has the minimum distance from the axis of the through hole 211.

[0050] When one end of the clamping piece 23 moves along the groove bottom in the second section 2212 away from the first section 2211, the other end of the clamping piece 23 moves away from the axis of the through hole 211 along the radial direction of the through hole 211.

[0051] When one end of the clamping piece 23 moves along the groove bottom in the second section 2212 close to the first section 2211, the other end of the clamping piece 23 moves close to the axis of the through hole 211 along the radial direction of the through hole 211.

[0052] The first segment 2211 and the second segment 2212 are arranged circumferentially along the through hole 211. The end of the first segment 2211 facing the second segment 2212 is connected to the end of the second segment 2212 facing the first segment 2211. The bottom of the groove 2213 of the end of the second segment 2212 facing the first segment 2211 is connected to the bottom of the groove 2213 of the first segment 2211, so that the end of the clamping member 23 can slide between the bottom of the groove 2213 of the first segment 2211 and the bottom of the groove 2213 of the second segment 2212.

[0053] Therefore, when the base 21 is stationary and the moving part 22 moves along... Figure 6 When rotating in direction a as shown, the end of the clamping member 23 moves from the second section 2212 to the first section 2211. The reaction force of the end of the clamping member 23 on the groove bottom 2213 of the first section 2211 extends radially along the through hole 211 to avoid the clamping member 23 being subjected to a tangential reaction force along the through hole 211. This allows the clamping member 23 to self-lock when it moves into the first section 2211, preventing the clamping member 23 from detaching from the surface of the bar stock 200 during processing within the clamping assembly 20.

[0054] In some embodiments provided in this application, the substrate 21 is provided with a plurality of recesses 221, which are arranged circumferentially along the through hole 211. There are a plurality of clamping members 23, and one or more clamping members 23 are correspondingly provided in the recesses 221.

[0055] like Figure 6 As shown, multiple settling tanks 221 along Figure 6 As shown in the diagram, multiple clamping members 23 are arranged along direction a. Figure 6 As shown in the diagram, the multiple clamping members 23 are arranged in a one-to-one correspondence with the multiple sinkers 221. Thus, by setting multiple clamping members 23, the support of the multiple clamping members 23 on the bar stock 200 can be distributed along the circumference of the bar stock 200, thereby improving the clamping stability of the clamping fixture 100 provided in this application on the bar stock 200.

[0056] In other embodiments (not shown in the figure), a plurality of clamping members 23 are arranged in a sink 221, and the plurality of clamping members 23 can simultaneously abut against the bottom 2213 of the first section 2211.

[0057] In some embodiments provided in this application, the clamping member 23 includes a claw portion 231 and an elastic portion 232, the elastic portion 232 being pressable against the end of the claw portion 231 near the movable member 22 between the base 21.

[0058] like Figure 6As shown, the clamping jaw portion 231 extends through the base 21 and along the radial direction of the through hole 211, one end of the clamping jaw portion 231 extends into the through hole 211 to be suitable for clamping the bar 200, and the other end of the clamping jaw portion 231 extends to the outside of the base 21 and abuts against the groove bottom 2213 of the sink 221. When the movable member 22 rotates relative to the base 21 along the a direction shown in Figure 6 When the movable member 22 rotates relative to the base 21 along the a direction shown in

[0059] Thus, when the base 21 is stationary and the movable member 22 rotates relative to the base 21 along the direction opposite to the a direction shown in Figure 6 , the elastic portion 232 generates a force on the clamping jaw portion 231 towards the groove bottom 2213 of the sink 221, so that the end of the clamping jaw portion 231 continuously abuts against the groove bottom 2213 of the sink 221, and the clamping jaw portion 231 is reset, so as to facilitate the disassembly of the bar 200 from the clamping assembly 20.

[0060] In some embodiments provided in the present application, the clamping jaw portion 231 extends along the radial direction of the through hole 211, the clamping jaw portion 231 is provided with a stop portion 233, the stop portion 233 is located on the side of the base 21 facing the movable member 22, an elastic member is clamped between the stop portion 233 and the base 21, and the distance between the stop portion 233 and the end of the clamping jaw portion 231 close to the axis of the through hole 211 is adjustable.

[0061] As shown in Figure 6 , the stop portion 233 is a nut, and the distance between the stop portion 233 and the end of the clamping jaw portion 231 facing the groove bottom 2213 of the sink 221 can be adjusted by rotating the stop portion 233, so as to adjust the deformation amount of the elastic member when the clamping member 23 clamps the bar 200, to adjust the pressure between the clamping jaw portion 231 and the groove bottom 2213 of the sink 221 by adjusting the radial position of the stop portion 233 on the clamping jaw portion 231 along the through hole 211, and to adjust the friction between the clamping jaw portion 231 and the groove bottom 2213 of the sink 221.

[0062] In some embodiments provided in the present application, one of the base 21 and the movable member 22 is provided with an annular flange 222 extending along the circumferential direction of the through hole 211, and the other of the base 21 and the movable member 22 is provided with an annular groove 212, and the annular flange 222 is rotatably fitted into the annular groove 212.

[0063] In some embodiments, as shown in Figure 4 , the movable member 22 is provided with the annular groove 212, and the base 21 is provided with the annular flange 222, and the annular groove 212 and the annular flange 222 both extend along the a direction shown in Figure 3 , and the annular flange 222 is rotatably fitted into the annular groove 212, so that the movable member 22 can rotate relative to the base 21.

[0064] In some other embodiments (not shown in the figures), the base 21 is provided with an annular groove 212, the movable member 22 is provided with an annular flange 222, and the annular flange 222 is rotatably fitted in the annular groove 212 so that the movable member 22 can rotate relative to the base 21.

[0065] In some embodiments provided in this application, the clamping assembly 20 further includes a fixing member 24, which is fixedly connected to the adjusting assembly 30. The base 21 is rotatably disposed on the fixing member 24 along the circumferential direction of the through hole 211. The fixing member 24 is provided with a locking member 241, which can abut against the base 21 to fix the base 21 relative to the fixing member 24.

[0066] like Figure 2 As shown, the fixing member 24 is fixedly connected to the adjusting member 32. The fixing member 24 is sleeved on the outer periphery of the end of the base 21 along the first direction x. The base 21 is rotatably connected to the fixing member 24 through the bearing 25. The end of the bearing 25 along the first direction x is provided with a retaining spring 26 to fix the inner ring of the bearing 25 on the base 21. The through hole 211 passes through the fixing member 24 along the first direction x. Thus, on the one hand, the base 21 is connected to the adjusting assembly 30 through the fixing member 24, and on the other hand, the bar 200 can be rotated along its circumference after the clamping assembly 20 clamps the bar 200.

[0067] The locking member 241 is a screw, which is threaded onto the fixing member 24. The end of the locking member 241 extends toward the base 21 along the first direction x. The end of the locking member 241 can abut against the end of the base 21 along the first direction x, so as to fix the base 21 and the fixing member 24 together by the locking member 241 and prevent the base 21 from rotating.

[0068] In some embodiments provided in this application, the adjustment assembly 30 includes a swing arm 31 and an adjustment member 32. The seat 10 is provided with a hinge. One end of the swing arm 31 is rotatably connected to the hinge, and the other end of the swing arm 31 is connected to the fixing member 24. The adjustment member 32 is snapped between the swing arm 31 and the seat 10, and the distance between the adjustment member 32 and the hinge is adjustable.

[0069] like Figure 2 As shown, the seat 10 along Figure 2 As shown in the xOy plane extension, the base 10 is adapted to mount the clamping fixture 100 provided in this application on the worktable 300. The swing arm 31 is hinged to the hinge seat, and the axis of rotation of the swing arm 31 relative to the base 10 extends along the first direction x. The adjusting member 32 can move along the second direction y. The adjusting member 32 is engaged between the swing arm 31 and the base 10 so as to adjust the angle of the extension direction of the swing arm 31 relative to the base 10 by the movement of the adjusting member 32 in the second direction y, thereby adjusting the distance between the clamping assembly 20 and the base 10 in the third direction z.

[0070] Therefore, by adjusting component 30, the distance between bar stock 200 in clamping component 20 and worktable 300 in third direction z is adjusted, that is, the height of bar stock 200 on worktable 300 is adjusted.

[0071] In some embodiments provided in this application, the seat 10 is provided with an assembly groove 11, the adjusting member 32 is slidably fitted in the assembly groove 11, the assembly groove 11 is provided with a threaded member 33, the threaded member 33 is rotatably connected to the inner wall of the assembly groove 11, and the threaded member 33 is threadedly fitted with the adjusting member 32.

[0072] like Figure 2 As shown, the assembly groove 11 extends along the second direction y and penetrates the seat body 10 along the third direction z. The end of the adjusting member 32 near the seat body 10 in the third direction z is slidably fitted in the assembly groove 11, and the end of the adjusting member 32 away from the seat body 10 in the third direction z abuts against the swing arm 31. The two ends of the adjusting member 32 in the first direction x are slidably connected to the inner walls of the two ends of the assembly groove 11 in the first direction x, so that the adjusting member 32 can slide in the assembly groove 11 along the second direction y.

[0073] Therefore, by rotating the threaded part 33, the position of the adjusting part 32 relative to the seat 10 in the second direction y can be adjusted, and the angle between the extension direction of the swing arm 31 and the xOy plane can be adjusted, thereby adjusting the distance between the clamping assembly 20 and the seat 10 in the third direction z.

[0074] In some embodiments provided in this application, the swing arm 31 is provided with a slide groove 311. The distance between the end of the slide groove 311 near the hinge and the seat 10 is less than the distance between the end of the slide groove 311 away from the hinge and the seat 10. The adjusting member 32 is provided with a slider, which is slidably assembled in the slide groove 311.

[0075] like Figure 2 As shown, the adjusting member 32 can move relative to the seat 10 in the second direction y, so that the slider can move in the second direction y. The extension direction of the slide groove 311 has an angle with the extension direction of the swing arm 31. Without changing the travel of the adjusting member 32 in the second direction y, the slide groove 311 amplifies the swing angle of the swing arm 31 relative to the seat 10, thereby increasing the travel of the bar 200 in the third direction z in the clamping assembly 20.

[0076] In some embodiments provided in this application, the base 10 can be a magnetic base so that the base 10 can be magnetically mounted on the worktable 300.

[0077] The following is combined with Figure 1 This application describes the processing equipment provided in the embodiments.

[0078] The machining device provided in the application comprises a workbench 300 and a clamping jig 100, the clamping jig 100 is the clamping jig 100 in any of the above embodiments, and the seat body 10 of the clamping jig 100 is arranged on the workbench 300.

[0079] As shown in Figure 1 , the workbench 300 extends along the xOy plane shown in Figure 1 , the workbench 300 is a magnetic workbench 300, so that the seat body 10 of the clamping jig 100 can be magnetically connected with the workbench 300 and fixed on the workbench 300.

[0080] Therefore, the clamping jig 100 provided in the application has the advantage of high clamping efficiency on the bar material 200, so that the machining device provided in the application has the advantage of high clamping efficiency on the bar material 200, thereby improving the machining efficiency of the machining device on the bar material 200.

[0081] In some embodiments, as shown in Figure 1 , the machining device further comprises a grinding tool 400, and the clamping jig 100 can adjust the distance between the bar material 200 and the workbench 300 in the third direction z, so as to adjust the distance between the bar material 200 and the grinding tool 400, thereby adjusting the machining size of the grinding tool 400 in the third direction of the bar material 200.
