传动轴厂传二车间五班生产的转向传动轴,是汽车的保安件零件。图A用M8612花键磨床加工转向传动轴花键齿侧,以前在使用过程中经常出现分度失灵,造成零件废,砂轮碰碎,操作者加工时精神紧张。每次维修机修工、动修人员的认识都不一致,兄弟单位帮助攻关也没彻底解决 The drive shaft of the transmission shaft factory, which is produced in five shifts of the workshop, is a part of the car’s security components. Fig. A uses the M8612 spline grinder to process the splined tooth side of the steering drive shaft. In the past, the indexing failure often occurred in the process of use, resulting in the waste of the parts, the grinding wheel crushing, and the operator’s nervousness during processing. Every time the maintenance technicians and mobilizers are inconsistent, their fraternal units have not solved the problem completely.
