Grinding device for outer ring machining of drum brake assembly

Abstract

The invention discloses a grinding device for outer ring machining of a drum brake assembly. A machine tool body, a fixed support, a grinding disc, a motor installed on the machine tool body, and the to-be-machined brake assembly are included. The to-be-machined brake assembly is arranged on the machine tool body and opposite to the grinding disc. The machine tool body is transversely provided with a first V-shaped guide rail. One end of the fixed support is installed in the first V-shaped guide rail and can move front and back in the first V-shaped guide rail. The other end of the fixed support is provided with a second V-shaped guide rail longitudinally in the length direction of the fixed support. One end of the grinding disc is installed in the second V-shaped guide rail and can move up and down in the second V-shaped guide rail. The grinding disc is provided with a grinding wheel and a grinding wheel motor driving the grinding wheel to rotate. The to-be-machined brake assembly is connected with an output shaft of the motor through an existing special tool and a key. The grinding device is simple in structure, convenient to use and high in production efficiency. Through the adjusting arrangement of the double V-shaped guide rails, the perpendicularity of a clamp and bouncing of a datum plane can be detected simultaneously on a machine tool, and the machining precision is improved.

Description

technical field [0001] The invention relates to the field of cylindrical grinding devices, in particular to a grinding device for cylindrical processing of a drum brake assembly. Background technique [0002] The brake is a safe part of the car, which plays the role of braking and deceleration. Therefore, the safety performance of the whole vehicle and the comfort during braking are an important evaluation index of the brake; as we all know, the types of friction plates of automobile brakes include Asbestos-free friction plates, semi-metallic friction plates, ceramic friction plates, paper-based friction plates, copper-based friction plates, graphite friction plates and other material formulations, no matter what kind of material, but its purpose is to ensure the effective manufacturing of automobiles. There are many ways to process the outer circle of the drum brake friction plate, such as the outer circle of the car friction plate, the outer circle of the friction plate, e...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a method to meet the requirements of verticality and runout of the outer circle of the drum brake friction plate, increase the effective contact area between the outer circle of the brake and the brake drum, increase the braking torque, and solve the problem of one-time off-line of the whole vehicle. The problem of low braking qualification rate can better ensure the accuracy after processing, and at the same time ensure the production efficiency of the drum brake assembly grinding device for external circle processing
