One side of the top end of the connecting seat 1 is connected to the bottom end of the transverse moving frame 5. The transverse moving frame 5 is horizontally rotatably connected with an adjusting screw 7. The bottom side of the inner part of the transverse moving frame 5 is slidably connected to the bottom end of the slider 8. The top end of the slider 8 is connected to the bottom end of a group of tooling clamps 2. A threaded sleeve 9 is horizontally arranged in the middle of the slider 8. The inner wall of the threaded sleeve 9 is screwed to the outer wall of the adjusting screw 7. The left end of the adjusting screw 7 is connected to the middle part of the inner end of the wrench 6. The right end of the adjusting screw 7 is connected to the inner end of the anti-slip contact block 13. The top right end of the transverse moving frame 5 is connected to the left bottom end of the connecting frame 10. The top end inside the connecting frame 10 is connected to the top end of the pressing piece 12 through a spring 11. The pressing piece 12 and the anti-slip contact block 13 are in movable contact. An installation structure is also arranged between the top of the connecting seat 1 and the tooling clamp 2; according to actual requirements, some tooling clamps 2 can be fixed at corresponding positions on the top end of the connecting seat 1 through the installation structure. Then, the wrench 6 can be rotated to make the adjusting screw 7 rotate under the constraint of the transverse moving frame 5. The adjusting screw 7 is screwed with the threaded sleeve 9 to drive the threaded sleeve 9 to drive the slider 8 to slide horizontally on the bottom side inside the transverse moving frame 5. After reaching the position, under the connection of the connecting frame 10, under the elastic pressing action of the spring 11, the pressing piece 12 acts downward to tightly press the outer side of the anti-slip contact block 13, preventing the adjusting screw 7 from self-rotating, forming a thread self-locking between the adjusting screw 7 and the threaded sleeve 9, and the slider 8 connecting the tooling clamp 2 is fixed at this position. Cooperating with other tooling clamps 2, it is fixed under the action of the clamping cylinder 3 and the clamping piece 4.

[0024] It also includes a sliding sleeve 14, a sliding rod 15 and a pulling piece 16. The inner side of the top of the connecting frame 10 is connected to the outer side of the sliding sleeve 14. The inner wall of the sliding sleeve 14 is slidably connected to the outer wall of the sliding rod 15. The bottom end of the sliding rod 15 is connected to the middle part of the top end of the pressing piece 12. The top end of the sliding rod 15 is connected to the middle part of the bottom end of the pulling piece 16; by holding the pulling piece 16, the sliding rod 15 can be slid upward in the sliding sleeve 14, and then the connecting pressing piece 12 can overcome the spring 11 to release the anti-slip contact block 13, facilitating the rotation of the wrench 6.

[0025] The installation structure includes an internal thread groove 17, a fixing bolt 18 and an installation through hole two 21. Multiple groups of installation through holes two 21 are arranged inside the connecting seat 1, and an internal thread groove 17 is arranged at the bottom of the tooling clamp 2. The fixing bolt 18 is detachably screwed inside the internal thread groove 17; according to requirements, the tooling clamp 2 can be placed at the corresponding position so that its internal thread groove 17 cooperates with the installation through hole two 21 at this position. The fixing bolt 18 passes through the installation through hole two 21 and is screwed and tightened inside the internal thread groove 17 to fix the tooling clamp 2 at this position.

[0026] It further includes a first mounting perforation 19. A plurality of groups of first mounting perforations 19 are arranged on the inner side of the outer end of the connecting seat 1. The connecting seat 1 can be fixedly mounted on the corresponding numerical control equipment through the first mounting perforations 19, improving the practicability.

[0027] It further includes anti-slip patterns 20. Anti-slip patterns 20 are arranged on the inner bottom side of each tooling clamp 2 and the bottom side of the clamping piece 4. Through the anti-slip patterns 20, the surface contact of the workpiece can be carried out, avoiding slipping and improving stability.

[0028] In summary, when a numerical control processing tooling for an anti-snake-shaped shock absorber seat for subways is in use, the connecting seat 1 is fixed at the corresponding position of the numerical control equipment through the first mounting perforations 19. According to actual requirements, the tooling clamp 2 can be placed at the corresponding position so that its internal thread groove 17 cooperates with the second mounting perforation 21 at this position. The fixing bolt 18 passes through the second mounting perforation 21 and is screwed and tightened in the internal thread groove 17 to fix the tooling clamp 2 at this position. Then, by holding the pulling piece 16, the sliding rod 15 can be slid upward in the sliding sleeve 14. Furthermore, the connecting and pressing piece 12 overcomes the spring 11 to loosen the anti-slip contact block 13. The wrench 6 can be turned, so that the adjusting screw rod 7 rotates under the restraint of the transverse moving frame 5. The adjusting screw rod 7 is screwed and matched with the threaded sleeve 9, so that the threaded sleeve 9 drives the slider 8 to slide horizontally on the inner bottom side of the transverse moving frame 5. After reaching the position, under the connection of the connecting frame 10, due to the elastic propping action of the spring 11, the pressing piece 12 acts downward to tightly press the outer side of the anti-slip contact block 13, avoiding the self-rotation of the adjusting screw rod 7 and forming the thread self-locking of the adjusting screw rod 7 and the threaded sleeve 9. The slider 8 is connected to fix the tooling clamp 2 at this position. Cooperating with other tooling clamps 2, it is fixed through the action of the clamping cylinder 3 and the clamping piece 4. Through the anti-slip patterns 20, the surface contact of the workpiece can be carried out, avoiding slipping and improving stability.

[0029] This clamping cylinder 3 is a well-known device for those skilled in the art directly purchased on the market. Here we only use it and do not make improvements to its structure and function. Therefore, we will not elaborate on it in detail here.
