In other embodiments, the grinding magnetic table 2 can be arranged above, left or right of the box body 1, and the positions of the grinding module 3 and the driving module 4 are adjusted according to the position of the grinding magnetic table 2. The driving module 4 can drive the grinding module 3 to move close to or away from the grinding magnetic table 2, and the grinding module 3 can grind the steel ring on the grinding magnetic table 2. Therefore, the specific position layout of the grinding magnetic table 2, the grinding module 3 and the driving module 4 is not limited herein.

[0030] The front side of the box body 1 is hingedly connected with a box door, the box door is provided with a door handle for facilitating opening of the box door, and the grinding magnetic table 2, the grinding module 3, the driving module 4, the first sensing module 5, the second sensing module 6 and the third sensing module 7 are all arranged in the box body 1.

The magnet can adsorb the steel ring to prevent the steel ring from moving and avoid position deviation of the steel ring during grinding.

[0032] The driving module 4 comprises a cylinder 41 and a lifting frame 42 driven by the cylinder 41 to move up and down. In order to ensure the stability of the lifting frame 42 moving up and down, a plurality of guide columns 43 are arranged on the lifting frame 42, and the upper and lower ends of the guide columns 43 are arranged on the upper and lower surfaces inside the box body 1. The lifting frame 42 comprises a first lifting plate 421 and a second lifting plate 422 arranged above and below, and the first lifting plate 421 and the second lifting plate 422 are fixed by a plurality of connecting columns 423. The upper end of the connecting column 423 is fixed on the first lifting plate 421, and the lower end is fixed on the second lifting plate 422. The first lifting plate 421 and the second lifting plate 422 are movably arranged on the guide columns 43 through linear bearings 44, which can ensure the stability of the first lifting plate 421 and the second lifting plate 422 moving up and down.
