[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example 1:

[0025] See also Figure 1-Figure 4The clamping assembly 4 includes a mounting plate 41 slidably connected to the inside of the workbench 1, and a C-shaped mounting frame 42 hinged on the upper surface of the mounting plate 41. An electric push rod A43 is hinged on the upper surface of the mounting plate 41. The telescopic end of the electric push rod A43 is hinged to the bottom of the C-shaped mounting frame 42. A motor A44 is fixedly installed on one side of the C-shaped mounting frame 42. A double-threaded rod 45 is fixedly installed on the output end of the motor A44. A mounting seat 46 is provided on the inner side of the C-shaped mounting frame 42. The double-threaded rod 45 runs through the interior of the mounting seat 46. The positive and negative threads on the outer surface of the double-threaded rod 45 are threadedly connected to a connecting block 47. An arc-shaped clamping block 48 is provided on one side of the two sets of connecting blocks 47, and the two sets of arc-shaped clamping blocks 48 are staggered and arranged opposite to each other. By moving the mounting plate 41 and adjusting the angle of the C-shaped mounting frame 42, it is convenient for the punching component 3 to punch holes on the pin shaft from different positions and angles, and the clamping method of the double-threaded rod 45 driving the arc-shaped clamping block 48 can provide a stable and balanced clamping force, ensuring that the pin shaft will not shake during the punching process, thereby improving the punching accuracy.

[0026] A protective layer 49 is provided on one side of each of the two sets of arc-shaped clamping blocks 48. The protective layer 49 is a component made of polyurethane to prevent excessive clamping force from damaging the outer surface of the pin shaft.

[0027] A moving component 5 is provided on the upper surface of the workbench 1. The moving component 5 includes a moving groove 51 opened on the upper surface of the workbench 1, and an electric push rod B52 fixedly installed on the inner wall of the moving groove 51. The telescopic end of the electric push rod B52 is connected to one side of the mounting plate 41. The position of the mounting plate 41 is moved by the telescopic movement of the electric push rod B52, so that the punching position of the pin shaft can be adjusted.

[0028] The punching assembly 3 includes a frame 31 fixedly mounted on the upper surface of the workbench 1, and a motor B32 fixedly mounted on the upper surface of the frame 31. A screw rod 33 is fixedly mounted on the output end of the motor B32. One end of the screw rod 33 passes through the frame 31, and the outer surface of the portion where the screw rod 33 passes through is threadedly connected to a movable frame 34. An electric push rod C35 is fixedly mounted on the inner wall of the movable frame 34. The telescopic end of the electric push rod C35 is fixedly mounted on a mounting frame 36. A motor C37 is arranged inside the mounting frame 36. The output end of the motor C37 is fixed. A drill rod 38 is installed, and a drill bit 39 is provided at the bottom of the drill rod 38. When the motor B32 is started, the screw rod 33 is driven to rotate. The movable frame 34 threadedly connected to the outer surface of the screw rod 33 will move up and down along the screw rod 33, thereby adjusting the height of the movable frame 34. Then, the electric push rod C35 is extended and retracted to push the mounting frame 36 to move inside the movable frame 34, that is, to fine-tune the positions of the drill rod 38 and the drill bit 39. Then, the motor C37 is started to drive the drill rod 38 and the drill bit 39 to rotate, thereby completing the drilling of the pin shaft.

[0029] A V-shaped groove 21 is provided on the upper surface of the placement table 2 , which not only keeps the pin shaft in a relatively stable state on the placement table 2 , but also allows the debris generated by drilling to fall into the V-shaped groove 21 , avoiding affecting the drilling effect.

[0030] A silica gel cushion 6 is provided on the upper surface of the placement table 2 to play a cushioning role.

[0031] Specifically, one end of the pin is placed between the two sets of arc-shaped clamping blocks 48, and then the motor A44 is started to drive the double-threaded rod 45 to rotate, thereby driving the two sets of arc-shaped clamping blocks 48 to move toward the center at the same time, and the two sets of arc-shaped clamping blocks 48 are arranged opposite to each other in an alternating manner, so that the pin can be clamped, and because one side of the two sets of arc-shaped clamping blocks 48 is provided with a protective layer 49 made of polyurethane, it is possible to avoid excessive clamping force damaging the outer surface of the pin, thereby providing a stable and balanced clamping force, ensuring that the pin will not shake during the punching process, and improving the punching accuracy. Then, according to the actual punching position, the angle of the pin is adjusted by the extension and contraction of the electric push rod A43, and the position of the mounting plate 41 is moved in combination with the extension and contraction of the electric push rod B52, so as to accurately adjust the punching position of the pin, making the equipment more flexible, and because the pin position On the upper surface of the placing table 2, a V-shaped groove 21 is opened on the upper surface of the placing table 2, and a silicone cushion pad 6 is provided on the upper surface of the placing table 2. Therefore, not only the pin shaft is kept in a relatively stable state on the placing table 2 and the vibration force generated by drilling is absorbed, but also the debris generated by drilling falls into the V-shaped groove 21 to avoid affecting the drilling effect. At this time, the motor B32 is started again to drive the screw rod 33 to rotate, and the movable frame 34 threadedly connected to the outer surface of the screw rod 33 will move up and down along the screw rod 33, thereby adjusting the height of the movable frame 34, and then the electric push rod C35 is extended and retracted to push the mounting frame 36 to move inside the movable frame 34, that is, to fine-tune the position of the drill rod 38 and the drill bit 39, and then the motor C37 is started to drive the drill rod 38 and the drill bit 39 to rotate, thereby completing the drilling of the pin shaft.
