汽车车架焊接工艺和工装设计探析

Analysis of Welding Process and Tooling Design of Automobile Frame

作为汽车制造与加工过程中的重要环节之一,汽车车架焊接工艺和工装设计,直接影响车架整体结构的稳定性、车体的性能及使用寿命。为全面了解汽车架构工艺,提高汽车的安全使用性能,文章对汽车车架焊接工艺进行了研究,然后,从定位基准的选择、车架纵梁定位、车架横梁定位、板簧支架定位等方面进行分析,最后,提出汽车车架工装设计要点。

As one of the important links in the process of automobile manufacturing and processing,the welding process and tooling design of automobile frame directly affect the stability of the overall structure of the frame,the performance and service life of the car body.In order to fully understand the automotive architecture process and improve the safe use performance of the car,this paper studied the welding process of the automobile frame,and then analyszed the selection of positioning datum,the positioning of longitudinal beam of frame,the positioning of cross beam of frame and the positioning of leaf spring bracket,and finally put forward the key points of the car frame tooling design.
