[0021] As a preferred solution, further, the clamping mechanism 3 includes two slide bars 31 installed transversely in the inner cavity of the box body 22, and the left and right ends of the outer wall of the slide bar 31 are respectively sleeved with a clamping plate 32, a first spring 33 and a sliding seat 34 from the inside to the outside, and the two ends of the first spring 33 are respectively connected to the clamping plate 32 and the outer wall of the sliding seat 34, and the clamping plate 32 is clamped when it moves inward, and the inner side of the clamping plate 32 is provided with an anti-slip edge to increase the friction with the accessory; The driving mechanism 4 includes a second motor 41 installed at the bottom of the box body 22, a third gear 42 is installed at the output end of the second motor 41, and a stopper 43 is installed on the top of the third gear 43. When the second motor 41 drives the third gear 42 to rotate, the movement trajectory of the stopper 43 can trigger the limiting mechanism 5. A rack 44 meshing with the third gear 42 is installed at the bottom of the slide 34. The two racks 44 are respectively located on the front and rear sides of the third gear 43, so that the rack 44 can pull the two slides 34 to move in opposite directions at the same time.

[0024] As a preferred solution, further, the extrusion block 614 is conical in shape. When the extrusion block 614 moves backward, the inclined surface of the extrusion block 614 can squeeze the brake block 612 outward, allowing the brake block 612 to adjust the angle of the telescopic rod 62.

[0025] As a preferred solution, further, the trigger assembly 63 includes an outer cylinder 631 installed at the bottom end of the telescopic rod 62, and the inner cavity of the outer cylinder 631 is respectively connected with a second spring 632 and a ejector pin 633 from back to front.

The trigger plate 634 prevents the ejector pin 633 from popping out of the outer cylinder 631, and a second travel switch 635 is installed at the front end of the inner wall of the outer cylinder 631. The first motor 24 is controlled to stop running by the second travel switch 635.

[0026] Working principle: Step 1: Move the rotating mechanism 2 through the mechanical arm 1 to make the clamping mechanism 3 close to the accessory. The second motor 41 drives the third gear 42 to rotate clockwise, and the two racks 44 move in the opposite direction. The racks 44 pull the slide 34 to move inward along the slide rod 31. When the stopper 43 on the third gear 42 triggers the first travel switch 56, the second motor 41 stops working, and the clamping plate 32 clamps the accessory under the elastic force of the first spring 33. Step 2: The first motor 24 drives the second gear 25 to rotate, and the box 22 rotates while the first gear 23 is stationary, thereby causing the accessory to rotate; Step 3: When the screw hole on the accessory passes through the ejector pin 633, the ejector pin 633 is passed through the screw hole under the elastic force of the second spring 632, and the trigger plate 634 triggers the second travel switch 635, and the first motor 24 stops working, so that the angle of the accessory can be adjusted. In the current state, the accessory is placed on the assembly by the robot arm 1, so that the accessory can be accurately installed; Step 4: When different types of auto parts need to be clamped, the moving slider 54 slides along the outer wall of the guide rod 53, and the moving slider 54 is positioned by screwing the positioning bolt 55, and the position of the first travel switch 56 is changed, thereby controlling the rotation angle of the third gear 42, so that the moving distance of the slide seat 34 is controlled, the compression amount of the first spring 33 is changed, and the clamping force of the clamping plate 32 is adjusted, which is suitable for grasping parts of different materials; Step 5, when it is necessary to adjust the installation angle of different accessories, turn the knob 613 to move the squeezing block 614 away from the brake block 612. The brake block 612 releases the brake on the telescopic rod 62, and the telescopic rod 62 changes the angle of the ejector pin 633. By turning the knob 613, the squeezing block 614 squeezes the brake block 612. The brake block 612 moves outward under the action of the inclined surface. The brake block 612 positions the telescopic rod 62. The telescopic rod 614 can also change the distance from the ejector pin 633 to the support rod 21. Therefore, the installation angle adjustment of different accessories is achieved, which is suitable for the installation and use of various accessories.
