Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle spring plates, in particular to an auxiliary tooling for an electric welding machine. Background Art

[0002] Leaf springs are long circular arcs of spring steel that are rectangular in cross section. In the most common configuration, the center of the arc provides the location of the axle, while the loops formed at either end attach to the vehicle chassis. For very heavy vehicles, leaf springs can be made from multiple leaves stacked together, usually with gradually shorter leaves.

[0003] Welding is a processing method for connecting multiple spring steel plates together. Commonly used welding methods include arc welding, gas shielded welding and laser welding. Welding processing requires mastering appropriate welding parameters and techniques to ensure the quality and strength of the welded joint.

[0004] When welding spring plates, manual handheld electric welders are mostly used. Since the inner wall and surface of the spring plates are arc-shaped, it is inconvenient to clamp the spring plates to be welded during welding, which makes the spring plates unstable during welding and reduces the work efficiency of spring plate welding. Therefore, we propose an electric welder auxiliary tooling. Utility Model Content
