With the rapid development of new energy vehicle manufacturing,introducing new energy vehicle models into the production line of traditional fuel vehicles and conducting flexible lean production of multiple vehicle models are the development trend of automotive manufacturing.Flexible reconfigurable tooling is a new type of flexible tooling.By overlaying and reconstructing on the tooling,it can achieve the switching of manufacturing vehicle models on the production line.It has advantages such as high flexibility and compact footprint,and has become a hot topic in this field.However,the increase in the flexibility of the fixtures will lead to a decrease in dimensional stability,becoming a bottleneck problem in the development of flexible lines.This article studies the design method of a flexible reconfigurable production line for the car bodies.Firstly,by comparing the differences in the structural characteristics between new energy and traditional car bodies,a design scheme for flexible reconfigurable tooling is proposed,and its dimensional stability is analyzed and verified.The experimental results and online inspection results prove that the flexible reconfigurable body production line designed in this article can not only solve the common production problems of new energy vehicles and traditional vehicle models,but also have good dimensional stability.It is of great significance for solving the problem of flexible hybrid production of new energy vehicles and traditional vehicle models.
