Abstract

The invention discloses an overlap welding tool suitable for a counterweight assembly of a rear frame of a hoisting traveling wheel type crane. The overlap welding tool comprises a base, equal-height pad assemblies arranged on the base, and cover plate positioning assemblies, side plate fastening assemblies and inclined plate positioning assemblies which are arranged on the base and distributed around the equal-height pad assemblies. According to the overlap welding tool suitable for the counterweight assembly of the rear frame of the hoisting traveling wheel type crane, all the positioning assemblies arranged on the base are used for accurately positioning and clamping all components of the counterweight assembly and performing welding assembling, so that the production efficiency is high, the product quality is stable, and the rejection rate is low; the requirement on the skill of a welding worker is reduced to a large extent, and the overlap welding tool is suitable for batch production.

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 hoisting a rear frame counterweight assembly 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 with a large number of steel plates during the production process, especially the counterweight assembly. [0003] At present, the welding of the counterweight 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 tech...
