Then, the fixing plate 11 is moved down to make the grinding belt 17 The bottom of the ball pin 5 is in contact with the ball head part. As the ball pin 5 is rotated by the installation mechanism, the grinding belt 17 can be used for fine grinding. During the grinding process, the slide plate 7 is moved in the direction away from the ball pin 5, thereby driving the entire fixed plate 11 and the connecting plate 13 to move synchronously. At the same time, the fixed plate 11 drives the connecting plate 13 to move downward, and the connecting plate 13 drives the grinding belt 17 to move downward synchronously. The connecting plate 13 is rotatably connected to the fixed plate 11. Therefore, when the slide plate 7 and the fixed plate 11 move, the connecting plate 13 will rotate, so that the grinding belt 17 always acts on the surface of the ball pin 5, thereby achieving the purpose of uniformly grinding the surface of the ball pin 5 in all directions.

[0027] Furthermore, a slide groove 6 is provided on the surface of the base plate 1, and a first electric telescopic rod 8 is fixedly installed on the inner wall of the slide groove 6.

Therefore, the connecting plate 13 is always subjected to the force of the torsion spring 15, so that the connecting plate 13 has a tendency to rotate toward the ball pin 5. Therefore, during the grinding process, as the fixed plate 11 moves downward and the slide plate 7 moves away, the grinding belt 17 can always act on the ball pin 5.

[0031] Furthermore, a limiting rod 12 is fixedly installed on the side wall of the fixed plate 11 relative to the position of the connecting plate 13 to achieve a state of limiting the position of the connecting plate 13. By setting the limiting rod 12, the connecting plate 13 will stay on the limiting rod 12 after being acted upon by the torsion spring 15, thereby facilitating the contact between the grinding belt 17 and the ball pin 5.

The connecting plate 13 and the fixed plate 11 are rotatably connected and connected by a torsion spring 15. Therefore, the connecting plate 13 is always subjected to the force of the torsion spring 15, so that the connecting plate 13 has The grinding belt 17 has a tendency to rotate toward the ball pin 5. Therefore, during the grinding process, as the fixed plate 11 moves downward and the slide plate 7 moves away, the grinding belt 17 can always act on the ball pin 5.
