The innovation of skill, the structure of automobile also become increasingly complex, and the performance of automobile is also become better and better.Exist much in the structure of automobile
Bend pipe and sketch plate, the presence of these bend pipes and sketch plate not only improve the structure connection of automotive interior so that vehicle structure
Become compacter, while but also the structural behaviour of automobile is greatly improved.These bend pipes and sketch plate usually have
Diversified shape, such as：Bend pipe shape is：Bend pipe both ends are opposite to each other to bending or bending in the same direction；Sketch plate some for abnormity
Combination of combination or two curved slabs of plate and tablet, etc..Although these bend pipes and sketch plate structure and by
In terms of power there is very big advantage, but also have inconvenience simultaneously, when the junction of bend pipe and sketch plate needs welding, due to tool
There is irregular shape, general fixture is difficult that bend pipe and sketch plate are fixed, this is to the weldering between bend pipe and sketch plate
Tape splicing has many inconvenience.The welding position inaccurate of bend pipe and sketch plate, the lighter may cause bend pipe and sketch plate junction
Discontinuity is welded, welding quality is low, and severe one may cause bend pipe and sketch plate junction to generate welding deformation.
Especially for the silencer pipeline that needs are formed by the different elbow pipe welding of both ends bending angle, existing fixture
Be difficult to be clamped bend pipe fixation, bend pipe be present in the welding process displacement or loosen the phenomenon that, and cause welding difficulty
It is big and frequently result in welding deformation or welding quality is low.
For this reason, it is necessary to fixture used in automotive muffler elbow pipe welding process is improved.
The content of the invention
