The positioning fixture of bonnet inseam automatic welding 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 is transmitted
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 direct 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 is caused problems of welded quality；
2) the unreasonable problems of welded quality caused of welding condition；
3) problems of welded quality that workpiece stiffening ring is caused with 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 do not find 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.
To sum up, bonnet oil leak, permeability phenomenon in axle housing manufacture are solved, it is most basic in addition to weld defect is solved the problems, such as
Solution is exactly to improve the weld strength of bonnet, and bonnet can be greatly improved after being welded by experiment detection to bonnet inseam
Weld strength, so as to fundamentally solve oil leak, permeability phenomenon after bonnet welding.Therefore drive axle is devised regarding to the issue above
Shell bonnet inseam automatic welding device, after driving axle housing bonnet inseam automatic welding device is accomplished by driving axle housing in welding
Lid is positioned, and requires accurate positioning, also wants the concentricity of guaranteed bonnet inseam position and bonnet, existing equipment can not
Meet this requirement.
To sum up, how to design a kind of can effectively solve determining for the problem of driving axle housing bonnet inseam automatic welding device being present
One of position device, the problem of becoming as those skilled in the art's urgent need to resolve.
