Description

Technical Field

[0001] The present invention relates to the technical field of a grinding device for brake shoes, and particularly to a grinding device for brake shoes. Background Art

[0002] Currently, brake shoes are core components in a vehicle braking system, mainly used in drum brakes to achieve deceleration or stopping through friction with the brake drum. The following is a detailed analysis integrating multiple sources of information: Definition and basic functions Core role, brake shoes are friction pairs of drum brakes, cooperating with the rotating brake drum to generate braking force through friction. When the driver steps on the brake, the brake shoes are pushed by an actuator (such as a wheel cylinder or a cam) against the inner wall of the brake drum, and the frictional force decelerates or stops the wheels. Energy conversion During braking, kinetic energy is converted into heat energy through friction, and the brake shoes need to have good heat dissipation performance to prevent braking failure caused by overheating. After the hoof blocks are completed by production molds, there are burrs generated during manufacturing at the joints at both ends of the outer friction surface of the hoof blocks and at the outer edges of the hoof blocks. In order to avoid burrs scratching the brake, since a single hoof block is in the shape of a semi-circular disk, the commonly used grinding devices are not convenient for clamping arc-shaped surfaces of different specifications, and it is necessary to manually control the hoof block to rotate in contact with the grinding disk, resulting in reduced grinding efficiency and high technical ability requirements for the staff; the existing grinding devices are not convenient for adjusting the grinding components in the left and right directions, reducing the practicability.
