Description

Technical Field

[0001] The utility model relates to the technical field of brake shoe production, in particular to a grinding device for brake shoes. Background Art

[0002] The brake shoe is the friction component of the drum brake. In addition to having the strength and rigidity required as a component, it should also have the highest possible and stable friction coefficient, as well as appropriate wear resistance, heat resistance, heat dissipation and heat capacity. When the brake shoe is in use, in order to better fit the brake disc, it needs to be polished during the production process.

[0003] The existing brake shoes are two braking mechanisms that cooperate with each other. The two cooperative shoes are disc-shaped as a whole, and a single shoe is a semi-circular disc. The outermost periphery of the shoe is the friction surface in contact with the brake, and the outer edge of the shoe surface in contact with the friction surface is approximately larger than the edge of the friction surface. After the shoe is processed by the production mold, there are burrs generated by manufacturing at the connection between the two ends of the outer friction surface of the shoe and the outer edge of the shoe. In order to avoid the burrs scratching the brake, since the single shoe is a semi-circular disc, the currently commonly used grinding device is not convenient for grinding arc surfaces of different radii, and manual control of the shoe rotation to match the rotation of the grinding disc is required, which reduces the grinding efficiency and requires high technical capabilities of the staff.

[0004] To this end, the utility model provides a grinding device for brake shoes, which facilitates the grinding of arc surfaces of brake shoes with different radii through the cooperation of motors, gears, rotating seats, rotating columns, mounting plates, slide grooves, I-shaped sliders, card slots and grinding discs to solve the above problems.
