Description

Technical Field

[0001] This utility model relates to the field of nut spot welding technology, and more specifically, to a quick-positioning nut spot welding device. Background Technology

[0002] In industries such as automobile manufacturing, home appliances, and precision hardware, nut spot welding is a common and critical process that allows multiple different components to be fixedly connected by bolts.

[0003] In traditional nut spot welding, manual handling of parts and tooling is often required. This is not only difficult to operate, but also prone to welding angle deviation, resulting in inaccurate hole positions on the welded parts. Since the spot welding machine head needs to touch the nut, the nut moves during the spot welding process, leading to poor spot welding quality. Traditional nut spot welding machines can usually only spot weld nuts of a single specification, which limits the applicability of nut spot welding work.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
