Universal tool for welding passenger car top cover framework

Abstract

The invention discloses a universal tool for welding a passenger car top cover framework. The universal tool comprises a tool bottom frame main body, a pair of linear guide rails, a plurality of guiderail sliding blocks, a plurality of positioning module assemblies, a plurality of positioning clamping blocks and a module positioning unit. According to the welding tool, the positions of the positioning module assemblies are rapidly switched on a sliding guide rail assembly and are fixed, so that the rapid adjustment of positioning modules in the length direction of the car is realized, and positioning of top cover framework of car model of the same series with different lengths; the positioning module assemblies of different shapes can be quickly replaced so that the modular replacement operation of the tool can be realized, the fixation of different series of car model frameworks can be met, the production efficiency can be improved to a certain extent, and reasonable operation is realized; kidney-shaped holes are formed in the positioning module assemblies, so that the size fine adjustment of the positioning modules in the width direction of the car body is realized; and meanwhile, the modular replacement operation of the tool is realized, and welding of different series of car model frameworks is achieved.

Description

technical field [0001] The invention relates to the field of welding auxiliary tooling, in particular to a general welding tooling for the roof frame of a passenger car. Background technique [0002] In the past ten years, my country's bus manufacturing industry has developed rapidly, and the shape, structure, variety and grade of bus products have made great progress. However, in terms of manufacturing technology, most bus manufacturers still use traditional methods for production. As far as the production of roof skin is concerned, this work is a process that needs to be improved urgently in the bus industry. Due to the limitation of equipment specifications, there are generally problems such as backward technology, low efficiency, unstable quality and high labor intensity. [0003] In the bus manufacturing process, it is necessary to weld the roof skin and frame of the bus together by means of resistance spot welding. The current domestic production form is to weld the to...

Problems solved by technology

[0004] However, with the rapid development of the automobile industry, the investment cost of a single model production line continues to increase. More and more automobile companies need to build flexible production lines that can meet the shared production of multiple models. Traditional positioning tools cannot meet the needs of flexible production.
