Abstract
Description
Technical Field
[0001] This invention belongs to the field of automotive body welding gun technology, specifically relating to a rotating and fixed welding gun device for welding body-in-white. Background Technology
[0002] Stamping welding does not require the addition of flux, filler, or other substances. It involves directly clamping two steel sheets on both sides with a large welding clamp and applying electricity. The high temperature and pressure at the moment of energization weld the two steel sheets together. It can also be considered as resistance welding. In automotive welding processes, the welding of all major components such as the basic body, frame, side panels, and five doors and one cover is completed using this welding process.
[0003] When the electrode caps become worn, deformed, or contaminated during use, they need to be repaired or replaced.
[0004] Electrode caps are crucial consumables in the welding process, and their condition directly impacts welding quality and efficiency. During prolonged welding operations, electrode caps gradually wear down due to high temperatures, high pressures, and friction with the workpiece. This wear may manifest as an uneven surface or a significant reduction in diameter. For example, when the wear reaches 10% to 15% of the original diameter, regrinding should be considered to restore its proper shape and size. Besides wear, electrode caps can also deform due to high temperatures. Deformed electrode caps not only affect the stable conduction of welding current but may also lead to increased spatter during welding and even welding defects. Therefore, if significant bending, twisting, or expansion is observed in the electrode cap, it should be replaced immediately.
[0005] Body-in-white welding, one of the three major processes in automobile production, plays a crucial role. Repair welding, in particular, is an important component of the welding process and a key factor in ensuring welding quality. Fixed welding torches are widely used in repair welding, ensuring that the position and angle of the torch remain constant throughout the welding process. This guarantees the stability and consistency of the weld, ensuring the integrity and strength of the vehicle body structure, and ultimately improving vehicle safety performance.
[0006] However, in certain special applications, it also has certain limitations. First, the fixed welding torch requires resharpening, and the direct-floor swing arm resharpening mechanism occupies a large space, causing interference problems during the body welding process. Second, electrode cap replacement is inconvenient, requiring manual entry into the production line for replacement, resulting in production line downtime and a significant waste of both time and energy, increasing production costs, which runs counter to the current advocacy of energy conservation, emission reduction, cost reduction, and efficiency improvement. Therefore, major component manufacturers are actively researching and developing various fixed welding torch mechanisms while designing fixtures. Summary of the Invention
