[0004] It was found during use of the above patent that: the above patent uses an arc-shaped clamping plate to clamp the brake pad, and uses a motor to drive the clamped brake pad to perform a grinding operation, but the outer side of the brake pad will be partially blocked when clamped by the arc-shaped clamping plate, and the clamping point needs to be replaced to complete the grinding of the entire outer arc section of the brake pad. On the other hand, the rotating body in the patent is a clamping component. It is known that in practice the brake pad is a central asymmetric component, and a large eccentric force will be generated during rotation, which seriously affects its clamping stability. Therefore, the design here in the patent is not practical. In order to solve the defects in the above technology, we propose a grinding device for the outer arc of the friction plate.
