Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a torsion half-axle adjustable welding tooling. Background Art

[0002] Among the many types of axles, the torsion axle assembly has a simple structure, low manufacturing cost, easy maintenance, and good shock absorption. Slight changes in tire angle when the left and right tires bounce can reduce tire wear. It takes up little space and can lower the height of the bridge floor. Torsion axle axle assemblies with different loads require different types of torsion half-axle welding assemblies due to different customer needs and different product styles. The angles of the torsion half-axle welding assemblies after welding are also different. As the types and styles of products increase, the same product has different performance loads and is divided into different specifications and models with different angle sizes. Each different model requires different specifications of welding positioning tooling for processing and welding, which will result in multiple and complex welding tooling models, high production costs, and difficult on-site management. Therefore, it is very necessary to produce a universal torsion half-axle assembly welding tooling to reduce tooling production costs and facilitate on-site management and use.
