Design And Simulation Of Main Automatic Welding Stationt For Commercial Vehicle Body-in-White

In the rapidly development of commercial vehicle body-in-white intelligent manufacturing industry,the welding assembly line is the key part of the four major processes of body production.The main task is that completing the assembly and welding process of the body-in-white stamping parts,the forward-looking and overall situation of its design,the automation and intelligence level of technology application has a direct influence on the quality and quantity,reliability and product upgrading of the whole vehicle.In this paper,a commercial vehicle cab of FAW Group main body-in-white auto welding station as the research object,mainly aiming at the technical problems brought by designing the welding line and the product update,and providing a set of solutions of process planning,structural designing and virtual simulating with the digital factory technology platform.Firstly,based on the plan of the production line and the structural characteristics of the cab body,analyzing and designing process plan for main assemble station;Then,according to the production pattern scheme and station structure,selecting matching product devices and designing three-dimensional structure of the key equipments;And doing mechanical analysis of key components of tooling;At the same time,using and the virtual manufacturing digital factory technology,establishing the robot automatic intelligent welding station of the main assembly station,simulating the welding path,the station timing and the production cycle,and verifying the rationality and reliability of the pre-process planning scheme and the tooling equipment structure;Finally,the field devices are debugged based on the process simulation data.In this paper,the process planning and tooling structure designing of the main assemble automatic welding station of commercial vehicle body-in-white are carried out,and obtaining the executable solution through virtual process simulation.And successfully applied to a commercial vehicle body-in-white welding line,it solves many practical technical problems for the enterprise,and improves the intelligent manufacturing level of the welding factory.
