我厂生产的YSK空调器用异步电动机的转子为双轴伸细长轴部件,在车削转子铁心外圆时,遇到了一定困难,转子轴伸细长且外圆对轴承挡的径向圆跳动要求较高,如图1所示。原采用三爪自定心卡盘夹紧,顶尖顶中心孔的加工方法,不易保证其加工精度。为改变工件在切削过程中的受力状态,减少径向圆跳动,我们采取了用 I produced YSK air conditioner induction motor rotor for the biaxial elongated long axis components, turning the rotor core in the outer circle, encountered some difficulties, the rotor shaft slender elongated and the outer circle of the radial bearing beating requirements Higher, as shown in Figure 1. The original three-jaw self-centering chuck clamping, top center hole processing method, not easy to ensure its processing accuracy. To change the workpiece in the cutting process of the stress state, to reduce radial circular beating, we have taken
