The wedge blocks 1001 are arranged one by one corresponding to the rollers 9. The upper surfaces of the wedge blocks 1001 are sloped, and the rollers 9 cooperate with the upper surfaces of the wedge blocks 1001.

[0035] When the core repairing disk 2 moves downward, the roller 9 cooperates with the upper surface of the wedge block 1001, so that the core repairing disk 2 moves downward while rotating, so that the grinding teeth 201 on the core repairing disk 2 grind the lower surface of the brake disc sand core, replacing manual work, which is convenient and fast and facilitates automated production.
