[0017] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0018] As shown in Figures 1-4, an automobile parts grinder includes a workbench 10, on which two symmetrically arranged grinding devices are installed, the grinding device includes a rotating ring 13, the outer peripheral side of the rotating ring 13 is sleeved with a grinding sleeve 21, the inner wall of the rotating ring 13 is provided with an inner groove 18, a turntable 16 is movably connected in the inner groove 18, the turntable 16 is fixedly connected to the inner wall of the rotating ring 13 by at least three elastic ropes 15, the material of the elastic ropes 15 is one of resin and rubber, a rotating shaft 17 is fixedly installed at the center of the rotating ring 13, connecting columns 12 are installed at the four corners of the top of the workbench 10, a top plate 11 is fixed on the connecting column 12, one end of the rotating shaft 17 extends into the top plate 11, two motors 22 are installed in the workbench 10, the other end of the rotating shaft 17 extends into the workbench 10, and a gear 23 is fixed thereon, the gear 23 is meshed with the motor wheel of the motor 22.

[0019] At least two limit grooves 19 are formed on one end face of the turntable 16, and at least two limit pins 20 are fixed on the inner wall of one side of the inner groove 18, and the limit pins 20 correspond to the limit grooves 19, wherein the limit grooves 19 are relatively wide to prevent the limit pins 20 from being unable to enter the limit grooves 19 during rotation and thus being stuck. At the same time, through the clamping of two movable grinding devices, it is possible to grind rocker arms 14 of different widths, and it can also automatically grind special-shaped curved surfaces, so that it can adapt to different types of rocker arms 14, greatly enhancing its applicability.

[0020] When in use, start the motor 22 to make the gear 23 drive the entire grinding device to rotate, and then insert the automobile rocker arm to grind its side surface. During the insertion process, since the rotating shaft 17 and the turntable 16 are stationary, the swivel 13 and the grinding sleeve 21 move to the side away from the rocker arm 14. During the movement, part of the elastic rope 15 will be stretched, so that the grinding sleeve 21 abuts against the surface of the rocker arm 14, and then the rotating shaft 17 rotates to drive the turntable 16 to rotate. The rotation of the turntable 16 will abut against the limit pin 20 through the limit groove 19, thereby driving the swivel 13 and the grinding sleeve 21 to rotate, thereby grinding the surface of the rocker arm 14, and the tension of the elastic rope 15 replaces the pressure between the grinding sleeve 21 and the rocker arm 14, thereby increasing its grinding effect.

[0021] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
