摘　　要：某中型货车车架与传统小微型货车车架相比,由于承载要求变高,传统电阻焊连接工艺无法适用,需使用铆接和螺接工艺。为满足中型货车车架制造精度及生产节拍的需求,需结合传统小微型货车车架工艺及结构进行改进设计。该文从零件间连接方式、螺接螺母选择、工艺布局优化、工装夹具定位方式、工艺设备的选择等方面,阐述了实现新要求的优化方案。Compared with traditional small and micro truck frames,the frame of a certain medium-sized truck requires higher load-bearing requirements,and traditional resistance welding connection technology is not applicable,requiring the use of riveting and screw connection processes.To meet the manufacturing accuracy and production rhythm requirements of medium-sized truck frames,it is necessary to improve the design by combining traditional small and micro truck frame technology and structure.This article elaborates on the optimization plan for achieving new requirements from the aspects of connection methods between parts,selection of screw nuts,optimization of process layout,positioning methods of tooling fixtures,and selection of tooling equipment.
