摘　　要：随着市场对整车质量要求的不断提高,提高车门的安装精度也成为各主机厂的一项重要课题。车门的安装精度主要受生产中公差累积的影响,文章通过使用适当的工具进行合理的公差分配,并借鉴优势安装结构等方法,使各安装工序的公差累积可控,使安装精度得到了有效提升,满足了顾客的要求。该方法虽然无法彻底消除生产过程中的误差,但是可以对误差发生的原因进行分析和控制,将影响降到最小。With the increasing improvement of the requirements of wchicle quality, improving the assembly precision of auto door has become an importanl subjecl. Assembly precision of door is mainly influenced by the production tolerance accumulation, hy using appropriale tools, reasonable allocation of tolerances, dnm＇ lessons from advanlage assembly slruclure methods, and the tolrance accumulation of assembly process is controllable. Assembly precision is improved effectively and custotmer requiremenl is reel. The error in production process can nol be complelely eliminated, but a,mlyzing and controlling the reasons led to en＇ors, the influence will be minimized.
