Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a welding tooling fixture for special-shaped plates. Background Art

[0002] In the existing special-shaped plate welding process, there are often challenges in accurate positioning and stable welding. Traditional welding fixtures usually position the special-shaped plate through various limiting components before welding. However, this positioning method has certain limitations. Since it only relies on the fixation of limiting components, it is easy to cause error accumulation during welding, especially when it is necessary to weld a straight line from the middle of the front end to the middle of the rear end. Due to inaccurate positioning, the straight line of the special-shaped plate after welding may have a slight inclination, affecting the quality and performance of the product.

[0003] Therefore, it is imperative to redesign a special-shaped plate welding fixture to ensure that the welded special-shaped plate is straight and has no inclination, and to improve the welding accuracy and stability. Utility Model Content
