Embodiment Construction

[0020] Examples such as figure 1 As shown, a cylindrical grinding device for a drum brake assembly includes a grinding disc 5 on which a grinding wheel 7 is mounted, and a brake assembly 8 is fixed on one side of the grinding disc 5 through a special tooling.

[0021] The central axis of rotation of the brake assembly 8 is parallel to the central axis of rotation of the grinding disc, and the special tooling for fixing the brake assembly 8 is mounted on the motor output shaft 9 through a key connection, and the motor output shaft 9 is connected to the motor. Connect, do clockwise rotation at a certain speed.

[0022] A grinding wheel motor 6 is installed above the grinding disc 5, and the grinding disc 5 is connected with the grinding wheel motor 6 through a shaft coupling. The grinding disc 5 is installed on the fixed support 2, and the fixed support 2 is provided with a longitudinal feed V-shaped guide rail 4, and the grinding disc 5. The hydraulic cylinder can be displaced...

Abstract

The invention discloses a counter-roll grinding device and process for a drum brake assembly. The counter-roll grinding process comprises the steps of firstly, mounting and fixing a workpiece on a special tool, and starting a grinding head to rotate clockwise; secondly, rapidly moving a fixed support and the grinding head to size positions along a horizontal V-shaped guide rail, and regulating the moving stroke distance through an inductive switch; thirdly, starting a main shaft of the workpiece to rotate clockwise; fourthly, driving the grinding head to perform working feed along a longitudinal V-shaped guide rail until finishing the processing of the workpiece, and regulating the stroke height through the inductive switch, wherein the a fixed support and grinding head assembly can be manually tuned on the horizontal V-shaped guide rail to ensure the size of the workpiece; and fifthly, after reaching the limit and meeting the inductive switch, horizontally relieving a cutter for 5-10mm, and rapidly returning to an origin position to finish the primary double-roller grinding of the brake assembly.

Description

technical field [0001] The invention relates to a method for processing the outer circle of a drum brake assembly, in particular to a new type of roller grinding process for a drum brake assembly, which belongs to the category of the automobile manufacturing industry. Background technique [0002] The brake is a safety component 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 automobile brake friction plates include asbestos / non-asbestos 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 braking and deceleration of the car. There are many ways to process the outer circle of the drum brake ...
