Description

Technical Field

[0001] This utility model belongs to the field of assembly equipment, and in particular relates to a welding fixture for a ladder. Background Technology

[0002] Ladders need to be fixed in the working position during use. For jobs that are frequently used or do not require changing the position of the ladder, the ladder needs to be fixed near the working position by connecting parts. In the existing technology, the ladder is composed of two vertical tubes and a horizontal plate located between the two vertical tubes. The two ends of the horizontal plate are fixed to different vertical tubes respectively, and L-shaped plates are often used to fix the ladder. The L-shaped plates have through holes for fixing. In order to improve the stability of the ladder, the L-shaped plates are often welded to the ladder vertical tubes on both sides of the ladder.

[0003] Currently, the welding process for ladder legs involves assembling and welding the L-shaped plates, vertical pipes, and horizontal plates manually. Workers place each component on a platform, hold it by hand at the welding position, and then weld. This process is prone to poor weld quality due to the instability of human hands. Furthermore, workers' inaccurate judgment of dimensions and distances can easily lead to misalignment during welding, resulting in poor product quality and affecting usability. Utility Model Content
