An automatic cutting equipment for axle brake shoes

Abstract

The invention discloses a device capable of realizing automatic cutting and trimming of axle brake shoes. The centering and locking mechanism on the equipment is used for accurate centering, positioning, support and locking and anti-loosening of the main engine and the axle end of the axle, so as to ensure the center reference positioning during rotary cutting; the servo power slewing mechanism installed on the equipment , which is used to drive the cutting mechanism to rotate forward and reverse at regular intervals; the cutting tool feed mechanism installed on the equipment is used for the lateral movement of the turning tool along the width direction of the shoe when cutting the shoe and the return of the turning tool after cutting origin. The invention can enable workers to easily and accurately complete the same-sized cutting and trimming of the brake shoes at both ends of the axle, and can realize automatic rotary cutting, automatic lateral feed and automatic return of the turning tool to the original position.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to an automatic cutting equipment for axle brake shoes. Background technique [0002] The axle brake of the vehicle has two types of drum type and disc type structure. It is an important part of the axle and one of the main components of the driving system. [0003] Drum brakes include axles, brake brackets, brake shoes and brake drums. The brake shoes in the brake are installed at both ends of the axle, and the brake shoes at each end are two petals. The two petals brake When the shoe is opened in the brake working state, it becomes a full circle, and the outer diameters of the two ends of the full circle should be the same. If the roundness of the full circle of the brake shoe is not enough or the outer diameter of the full circle of the brake shoe at both ends of the same bridge is too different, side deviation and side movement will occur when the brake is runn...

AI Technical Summary

Problems solved by technology

[0004] In the past, after installing the brakes and hanging the brake shoes on the axle assembly line, the consistency of the brake stroke on both sides was only ensured by adjusting and measuring the brake clearance. Whether the dimensions of the outer circles of the brake shoes at both ends are the same after opening, there is basically no online detection and internal control, which brings uncertainty to the braking performance of the axle

There are also axle manufacturers, because the quality of the externally supplied brake assembly is uncertain, so the outer circle is trimmed by simple manual shoe cutting tooling, but the efficiency is very low, and the quality is difficult to be effectively controlled
