Design and Debugging of Semi-Self-automatic Welding Equipment for Bus Roof-hood Skin

摘要

In the research of using arc spot welding to connect roof-hood and skeleton of bus, the semi-self-automatic welding equipment for bus roof-hood has the advantages of easy to operate, high quality, low cost, small deformation of work-piece in heating welding and so on. So, it can be used in enclosing roof-hood and connecting skeleton of bus. This research aims at the solution to some key technical problems of designing, manufacture and debugging of semi-self-automatic welding equipment for bus roof-hood skin, as well as selecting proper connecting construction, improving technology, modifying design and enhancing quality of spot weld. The equipment design includes of gantry frame system, positioning fixture system and welding system. The success of developing semi-self-automatic welding equipment for bus roof-hood will solve the problem of the production technology for bus roof-hood.
