Description

Technical Field

[0001] The utility model relates to the technical field of brake pad grinding, in particular to a device for grinding the inner arc surface of a vehicle brake pad. Background Art

[0002] Automobile brake pads, also known as automobile brake leathers, refer to friction materials fixed on brake drums or brake discs that rotate with the wheels. The friction linings and friction blocks bear external pressure, generating friction to achieve the purpose of decelerating the vehicle. Automobile brake pads are generally composed of steel plates, adhesive insulation layers, and friction blocks. After being fixed to the steel plates, the friction blocks need to be polished flat to meet the requirements of use. Grinding also includes grinding the inner arc surface, but the existing grinding equipment cannot adapt to brake pads of different sizes, and the grinding head needs to be replaced, or the adjustment structure is too complicated, which is not convenient for later maintenance.
