摘　　要：针对数控车床主轴部件的装配的质量,提出了主轴装配工艺应满足的精度要求,并对产生误差的原因进行了分析。针对主轴滚动轴承的预紧对装配质量的影响,介绍了数控车床主轴轴承的预紧方法。同时为了保证主轴部件的装配质量,减小误差,提高工效,通过实践反复推敲,自行设计制造了一套装配检测工装器具,并且经过实践论证制定了主轴装配任务指导文件,提出了主轴装配工艺的制定并详细介绍了操作要领。Concerning the spindle assembly quality of NC lathe,the precision for spindle assembly required by the processing plan is put forward in this paper,and an analysis for error caused is made as well.Then the pre-tightening method for spindle bearing of the NC lathe is introduced aimed at the effect on assembly quality caused by pre-tightening rolling bearing of the spindle.Meanwhile,a set of tooling for assembly and checking is designed independently through repeated practice to assure assembly quality and to decrease error as well as improve the work efficiency.By repeatedly experiment,a guidance file is formulated in which process for spindle assembly is set and the relative operating essentials are provided.
