Description

Technical Field

[0001] The utility model relates to the field of riveting and welding, in particular to a square arm riveting and welding device. Background Art

[0002] Aerial booms are a crucial component of aerial work equipment. They consist of multiple square arms, each of which is riveted and welded together from a base plate, two side plates, and a top plate. During welding, the arms must maintain the perpendicularity and parallelism of the base, top, and side plates. The current riveting and welding process for these arms involves manual marking and adding internal supports for positioning, followed by external clamping of the two side plates using a fixture. Because the arm is approximately 8 meters long, traditional welding methods can lead to significant product deformation, making it difficult to ensure straightness and flatness, and removing the internal supports is also challenging. Furthermore, the use of multiple fixtures to clamp the two side plates requires both time-consuming and labor-intensive assembly and disassembly. Furthermore, the presence of the fixtures interferes with the movement of the welding torch, impacting the welding operation.

[0003] Based on this, the present application provides a square arm riveting device to solve the above problems. Utility Model Content
