The invention discloses an overlap welding tool suitable for a middle assembly of a rear frame of a hoisting driving wheel type crane. The overlap welding tool comprises a front support positioning device used for positioning a front support assembly of the middle assembly, side frame positioning devices used for positioning side frame assemblies of the middle assembly, side frame fastening devices used for fixing the side frame assemblies of the middle assembly and matched with the side frame positioning device, and a middle vertical plate positioning device used for positioning a middle vertical plate of the middle assembly, wherein the side frame positioning devices, the side frame fastening devices and the middle vertical plate positioning device are located on the same side of the front support positioning device. According to the overlap welding tool suitable for the middle assembly of the rear frame of the hoisting driving wheel type crane, the positioning devices and the fastening devices which are arranged on a base are used for accurately positioning and fixing all components of the middle assembly of the rear frame, then welding and assembly are conducted, the production efficiency is high, the product quality is stable, the rejection rate is low, and the requirements for skills of welders are lowered.
Description
technical field [0001] The invention belongs to the technical field of engineering machinery processing equipment, in particular, the invention relates to a lap welding tool suitable for the middle assembly of the rear frame of a traveling wheeled crane. Background technique [0002] In the hoisting traveling wheeled crane in the prior art, the weight of the rear frame has an important safety effect on the crane. The rear frame is welded by a large number of steel plates in the production process, especially the middle assembly part. [0003] At present, the welding of the central assembly mostly uses some simple measuring tools to draw lines manually, and then uses some simple process supports to fix the relevant dimensions of the product and perform spot welding. There is no corresponding welding mold, the welding time is long, the processing technology is complicated, the production efficiency is low, the product quality is unstable, the welding technology level of the w...
