[0002] Polishing refers to a processing method that uses mechanical processing to reduce the surface roughness of metal parts to obtain a bright and flat surface. Polishing is usually performed using a polishing wheel, so the workpiece needs to be clamped during polishing to avoid shaking of the workpiece during polishing. However, the workpiece is generally clamped by multiple clamping blocks that are close to the workpiece. However, after clamping, the multiple clamping blocks are prone to loosening due to the loosening of one clamping block, and the workpiece is prone to damage due to excessive clamping force during clamping.
