在加工如图1所示的工件中,我们采用了粘结镶套的方法,对所使用的同轴度量规(以下简称量规)在结构上进行了改进,解决了因量规而影响生产的问题,提高了量规的合格率。量规加工工艺的比较原量规的结构如图2所示,它由量套1和量杆2组成。量规孔D_0与导柱孔口都同时设计在量套上,它们之间的同轴度误差为φ0.003,结构为整体式。量套的主要工艺路线为:粗车——热处 In the processing of the workpiece shown in Figure 1, we use the method of bonding the sleeve, the use of coaxial gauges (hereinafter referred to as the gauge) in the structure has been improved to solve the problems caused by the rules and regulations affect the production , Improve the pass rate of the gauge. Gauge processing technology comparison The structure of the original gauge shown in Figure 2, which consists of a set of 1 and the amount of rod 2 composition. Gauge hole D_0 and guide post orifice are designed on the sleeve, the coaxial error between them φ0.003, the structure of the monolithic. The main set of process routes: rough car - heat
