摘　　要：高精度卧轴矩台平面磨床是国家标为M71系列平面磨床,即带有卧式磨头主轴,矩形工作台的平面磨床。该磨床的主要功能是用砂轮的周边磨削工件的平面,也可以用砂轮的端面磨削工件的槽和凸缘的侧面,磨削精度和光洁度都较高;适宜于磨削各种精密零件和工模具,可供机械加工车间、机修车间和工具车间作精密加工使用。高精度卧轴矩台平面磨床主轴系统的热变形是影响磨前加工精度的主要因素之一,为研究主轴系统温度分布随时间的变化规律,我们对高精度卧轴矩台平面磨床主轴系统的温度场进行了验证性分析并得到了卧轴部件加工质量对主轴系统达到热平衡时间以及对主轴系统的温度场的影响。优化卧轴矩台平面磨床的基础部件能够缩减主轴系统达到热平衡的时间并提高卧轴矩台平面磨床主轴系统的精度,基于此提出了改善主轴系统加工工艺的措施。The high precision horizontal axis moment table plane grinder is a national standard M71 series plane grinder,that is,it is a plane grinder with horizontal grinding head spindle and rectangular worktable.The main function of the grinder is to grind the plane of the workpiece with the periphery of the grinding wheel,or to grind the groove and flange side of the workpiece with the end face of the grinding wheel,which has high grinding accuracy and smoothness and is suitable for grinding all kinds of precision parts and dies.It can be used for precision machining in machining workshop,machine repair workshop and tool workshop.The thermal deformation of the spindle system of the high precision horizontal axis moment table plane grinder is one of the main factors affecting the machining accuracy before grinding,in order to study the variation of the temperature distribution of the spindle system with time.The temperature field of the spindle system of the high precision horizontal axis moment table plane grinder is verified and the influence of the machining quality of the horizontal shaft components on the thermal balance time of the spindle system and the temperature field of the spindle system is obtained.Optimizing the basic components of the horizontal shaft moment table plane grinder can reduce the time for the spindle system to reach the thermal balance and improve the accuracy of the spindle system of the horizontal shaft moment table plane grinder.Based on this,the measures to improve the machining technology of the spindle system are put forward.
