Research On The Key Technology Of Francis Welding Production Line Design

Automobile mixed model assembly welding line is in the same production line to complete the multi vehicle shell mixed production,its purpose is to reduce maintenance costs and operating costs,improve equipment utilization.In this paper,according to the layout theory,the welding line of automobile assembly is given in the production process and the process requirements,Overall layout design method for assembly welding line,To solve the problem of assembly line balance,the welding operation and welding fittings design division,and the simulation analysis of articles on the computer.Firstly,the factors that affect the equilibrium in the production line and the working time of the process are firstly determined,this paper estimates the welding time and artificial robot in different operation time in each station,Calculation basis for the balance of production line,then Determine the production beat of single vehicle and mixed flow production line,and divide the welding region.Subsequently,the method of the process synchronization is adopted,Consider the process characteristics of the vehicle itself and the capacity requirements,To the delivery method of the given field,the white body process flow and the production line,and the distance between the area and the station intercept constraints,The overall layout scheme of mixed flow production line is determined,which provides the basis for the following work.Finally,on the commercial software platform,the key procedure is designed based on the fixture locating principle,and the main welding station to establish the digital model.Carried on geometry simulation on robot welding trajectory and interference inspection.The results of the research were applied and verified in the design of a certain automobile factory.
