Automobile rear axle housing flange plate press-fitting welding device

Abstract

The invention discloses an automobile rear axle housing flange plate press-fitting welding device which is used for solving the problems of being multiple in procedure, low in mounting efficiency, incapable of guaranteeing welding precision of flange plates and the like in an existing automobile rear axle housing flange plate press-fitting process. The automobile rear axle housing flange plate press-fitting welding device comprises a combined lathe bed, welding mechanisms and a clamping mechanism. According to the technical characteristics, the combined lathe bed is composed of a main body lathe bed and side lathe beds, wherein the middle of the upper surface of the main body lathe bed is provided with a lifting clamping mechanism used for limiting and smoothing a rear axle housing; rotating mechanisms with adjustable feeding strokes comprise hydraulic feeding units and rotary driving units, and the welding mechanisms are arranged on the upper surfaces of the side lathe beds; and the clamping mechanism comprises a self-centering clamping mechanism and the lifting clamping mechanism, and the lifting clamping mechanism is adjusted to enable the axes of flange plates and the axis of an axle housing pipe to be located on the same central line. According to the automobile rear axle housing flange plate press-fitting welding device, the structural design is reasonable, the technological process is simplified, assembling and positioning are accurate, welding deformation is easy to control, while precision of the mounting surfaces of the flange plates is ensured, the machining costis reasonably reduced, the quality and production efficiency of a finished product are improved, and therefore driving safety is guaranteed.

Description

technical field [0001] The invention relates to a press-fitting and welding assembly of the flange plate and the axle housing tube of the axle, in particular to a device that combines the press-fitting and welding process of the flange plate of the rear axle housing and the axle housing tube, and reasonably controls The welding heat deformation of the flange plate is a press-fit welding device for the flange plate of the rear axle housing of the automobile. Background technique [0002] As one of the four main components of the vehicle driving system, the axle (rear drive axle) is used to transmit the forces in all directions between the frame (or load-bearing body) and the wheels. Generally, the axle can be divided into integral type and disconnected type, in which the integral type cooperates with the non-independent suspension, and the disconnected type supports the body through the respective suspension system, and does not need to be used with the independent suspension...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a press-fit welding device for the rear axle housing flange of an automobile, which solves the problem of many procedures, low installation efficiency, and inability to ensure the welding accuracy of the flange in the existing automobile rear axle housing flange press-fit process. The problem is that its structural design is reasonable, the process flow is simplified, the assembly positioning is accurate, and the welding deformation is easy to control. While ensuring the accuracy of the flange mounting surface, it reasonably reduces the processing cost, improves the quality of the finished product and production efficiency, thereby ensuring driving safety.
