Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of welding, and specifically relates to a welding clamp arm for a special vehicle production tool. Background Art
[0002] At present, the welding of special vehicle bodies, especially the welding of the side and bottom joints, is mostly done manually by overhead welding or by using professional flipping tooling to flip the workpiece before welding.
[0003] Patent No. 202022486575.2, a public specification published on September 14, 2021, discloses a deep throat welding pliers for spot welding ultra-thick stainless steel plates for rail transit vehicles. The pliers include a main body with a protective cover at the front end, a sliding groove on one side of the protective cover, a slider on the inner outer surface of the sliding groove, a cover handle on one outer surface of the protective cover, a retaining groove on the outer surface of the main body, a lower extension plate at the front end, a lower movable block on one side of the lower extension plate, and a fixing hole on one outer surface of the lower extension plate. The deep throat welding pliers for spot welding ultra-thick stainless steel plates for rail transit vehicles described in this utility model have a protective cover to protect the welding arm after use and prevent damage to the welding arm during transportation that would affect normal use. The extension plate, bolts, and slide groove facilitate movement of the welding arm and adjustment of the throat depth, making it suitable for processing different materials.
[0004] In the existing technology, overhead welders enter the bottom of the workpiece, which is very likely to cause personal injuries such as bumps and burns from welding slag; flipping tooling is still very practical for some small parts, but for larger workpieces, due to the weight of the workpiece itself and the large flipping inertia, flipping is extremely inconvenient or takes a long time.
