Automatic welding device for inner seam of rear cover of driving axle housing and application method for automatic welding device

Abstract

The invention discloses an automatic welding device for an inner seam of a rear cover of a driving axle housing. The automatic welding device comprises an integral base, a fully-closed protective cover, a positioning clamp, a turnover mechanism, a rotating mechanism and a robot welding system, wherein the fully-closed protective cover is arranged on the integral base, and the positioning clamp is arranged on the integral base and is arranged inside the fully-closed protective cover; a first through hole is formed in the middle of a mounting frame; the positioning clamp is arranged in the middle of the mounting frame; a supporting shaft penetrates through a supporting shaft sleeve and can rotate; two first supporting arms used for supporting the rear cover of the driving axle housing are arranged on the mounting frame and are located on the two sides of the positioning clamp separately; the mounting frame can turn over by taking a straight line where the axis of a machine head supporting base and the axis of a driven tailstock are located as an axis; a first driving motor is used for driving the mounting frame to turn over; and the supporting shaft rotates along with the positioning clamp and is used for supporting the positioning clamp to be prevented from falling off when the mounting frame turns over.

Description

technical field [0001] The invention relates to the field of automatic welding equipment for the inner seam of the rear cover of the drive axle case, in particular to an automatic welding device for the inner seam of the rear cover of the drive axle case and a method for using the same. Background technique [0002] In medium and heavy vehicles, the drive axle housing is the carrier that supports the load of the vehicle, bears the reaction force and moment from the road surface transmitted by the wheels, and transmits it to the frame (or body) through the suspension. It plays an important role, and its manufacturing quality has a direct impact on the quality of the whole bridge and even the whole vehicle. The oil leakage and oil seepage phenomenon of the welding seam of the rear cover of the drive axle has always been one of the common problems in the manufacture of the axle housing. Due to oil leakage and oil leakage from the welding seam of the rear cover of the axle hous...

AI Technical Summary

Problems solved by technology

[0004] 1) Welding quality problems caused by unclean workpiece surface or welding torch angle deviation;

[0005] 2) Welding quality problems caused by unreasonable welding process parameters;

[0006] 3) Welding quality problems caused by the inconcentricity of the workpiece reinforcement ring and the back cover;

Long-term bending fatigue causes cracks in the back cover, resulting in oil leakage and oil leakage
