Wherein, two driving assemblies 40 are arranged on the rear side and the right side of the ball 20 respectively, and two driving assemblies 40 are used for driving the ball 20 to rotate in two mutually perpendicular directions.

[0044] The working principle of the embodiment is that the ball 20 is arranged in the support part on the rack 10, and the ball 20 is driven to move in the support part through the cooperation of two driving assemblies 40, so that the ball 20 can be angularly rotated. After the grinding wheel to be corrected is installed on the mounting table 30 on the top of the ball 20, the mounting table 30 is driven by the ball 20, and the mounting table 30 moves together with the grinding wheel. Through the technical scheme, the grinding wheel can be adjusted at multiple angles when the grinding wheel is dressed.

[0045] In one specific embodiment:

[0046] The locking piece 50 comprises a stud 51 and a nut 52, one end of the stud 51 is fixedly arranged on the top of the ball 20, and the nut 52 is matched with the stud 51. In the process of installing the grinding wheel, the stud 51 passes through the hole in the middle of the grinding wheel, and then the nut 52 is driven by a wrench or the like tool, and the grinding wheel is fixed on the stud 51 through the nut 52.

[0047] Preferably, a support plate 53 is arranged between the stud 51 and the ball 20, and the bottom of the grinding wheel is in contact with the support plate 53 when the grinding wheel is installed.
