Technical Field
[0001] The utility model relates to the technical field of drum brake pad processing, in particular to an outer arc grinding device for a drum brake pad. Background Art
[0002] Drum brakes have a cast iron part shaped like a tambourine, called a brake drum, which is fixed to the tire and rotates at the same speed. Disc brakes have the advantages of better responsiveness and stability, better heat dissipation, and easy replacement. Drum brakes have lower costs and higher absolute braking force, and are more commonly used on the rear wheels of small cars. However, their wear rate is higher, so the overall cost is also higher; during the production of drum brake pads, the outer arc of the brake pads needs to be polished by a corresponding polishing device. However, when the current polishing device is polishing the outer arc of the brake pad, a lot of polishing dust will be produced, and some polishing debris will also fly out, which will pollute the air in the polishing area.
