Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and belongs to a RV trailer linkage assembly and automated welding fixture. Background Technology

[0002] Currently, the welding process for RV trailer linkages primarily employs a manual, step-by-step operation. The process consists of four stages: First, operators manually place the linkage body, hinge lugs, and other components into an open, standard mold, relying on visual inspection for initial positioning. Next, a handheld CO2 gas shielded welding machine is used to intermittently spot weld the connection points, with the welding spacing and number of welds controlled by the welder's experience. After initial fixing, the original operator or another welder performs continuous full-scale welding, requiring frequent adjustments to the welding torch angle and welding parameters. The final stage involves manually flipping the workpiece to complete multi-sided welding, typically requiring 3-5 clamping adjustments. The entire process lacks automated equipment support, with key steps relying heavily on the welder's skills and experience, resulting in welding quality being significantly affected by human factors.

[0003] Traditional assembly and welding mainly rely on manual operation, which has the following problems:

[0004] 1. Low efficiency of manual welding: Manual welding is slow and difficult to meet the needs of mass production;

[0005] 2. Difficulty in ensuring dimensional accuracy: Uneven heat output during welding leads to connecting rod deformation, affecting dimensional accuracy and assembly performance.

[0006] 3. Poor quality consistency: Manual operation is prone to defects such as uneven welds and incomplete penetration, which reduces product reliability;

[0007] 4. High cost: Reliance on skilled welders results in high labor costs and rework rates. Utility Model Content
