Description

Technical Field

[0001] The present invention relates to the field of steel structure civil air defense door leaves, and in particular to an automatic welding tooling platform for a one-way linear welding production line of a civil air defense steel structure door leaf. Background Art

[0002] Civil air defense door panels have two structures: reinforced concrete and steel. Steel-structured civil air defense doors are primarily constructed by splicing together channel steel, I-beams, and plates. The outer frame of the door panel is primarily composed of channel steel, with I-beams of varying lengths crisscrossing to form a grid. Multiple workers are required to assemble and weld the channel steel, I-beams, and plates. Currently, in the production of civil air defense door panels, manual welding can lead to unstable weld quality due to technical errors. Fatigue caused by long hours of manual welding reduces the quality of civil air defense door panel welding, leading to weld rework. Before welding, operators need to adjust the position of the profiles and plates, which are heavy and inconvenient to adjust. Summary of the Invention
