Description

A kind of driving axle housing bonnet inseam automatic soldering device

Technical field

The utility model is related to driving axle housing bonnet inseam automatic welding device field, and in particular to be a kind of drive axle Shell bonnet inseam automatic soldering device.

Background technology

Driving axle housing is support automobile load in medium-heavy automobile, bears the counter-force and counter-force on the road surface that wheel transmits Square, and pass through the supporting body that suspension is delivered on vehicle frame (or vehicle body), played an important role in medium-heavy automobile vehicle bridge, it is manufactured Quality produces directly influence on whole bridge or even on the quality of vehicle.The weld seam oil leak of drive axle rear cover, permeability phenomenon are always One of the problem of common in axle housing manufacture.Because the oil leak of axle housing bonnet weld seam, permeability cause bearings inside speed reducer and gear to obtain not To sufficient lubrication, abrasion is accelerated, and even occurs the phenomenon of " locking " when serious, can cause serious consequence.

The reason for causing the oil leak of axle housing bonnet, permeability is as follows：

1) due to workpiece surface is unclean or angle of welding gun deviation caused by problems of welded quality；

2) problems of welded quality caused by welding condition is unreasonable；

3) workpiece stiffening ring and problems of welded quality caused by bonnet decentraction；

But above reason can be solved by various means.It is right therewith that cutting physics and chemistry is carried out by different workpieces Than the problem of finding that some bonnets generate oil leak, permeability phenomenon, but not finding weld defect.It is strong by the weld seam to bonnet Degree carries out finite element analysis, it can be deduced that bonnet weld stress is concentrated and is primarily due to caused by rear axle housing flexural fatigue. Long-term flexural fatigue causes bonnet to crack, and causes oil leak, permeability.
