Automatic cutting equipment for vehicle axle brake shoe

Abstract

The invention discloses automatic cutting equipment capable of realizing the automatic cutting and trimming of a vehicle axle brake shoe. The automatic cutting equipment comprises an equipment regulation mechanism, a centering and locking mechanism, a servo power gyration mechanism and a cutting lathe tool feeding mechanism, wherein the equipment regulation mechanism is connected to the equipment,and is used for the balanced suspension of an equipment main engine and overcoming a moment generated by main engine revolution cutting; the centering and locking mechanism is installed on the equipment and is used for accurately carrying out centering, positioning, supporting, locking and loosening prevention on the main engine and a vehicle axle shaft end so as to guarantee central datum positioning during the revolution cutting; the servo power gyration mechanism is installed on the equipment for driving a cutting mechanism to carry out fixed-time forward-direction and reverse direction revolution; and the cutting lathe tool feeding mechanism is installed on the equipment for controlling the feeding lateral movement of the lathe tool along a shoe width direction during shoe cutting andcontrolling the lathe tool to return to an original point after shoe cutting. According to the automatic cutting equipment, the same-size cutting and trimming work of the brake shoes on two ends of the vehicle axle can be easily and accurately finished by a worker, automatic revolution cutting can be realized, and a purpose that the lathe tool automatically laterally moves to fed and automatically returns to an original place can be realized.

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
