锥孔大端直径测量方法的设计

Design of Measurement Method for Tapered Bore Big End Diameter

锥孔大端尺寸采用通用量具检测误差大,对于尺寸公差小的零件无法满足测量精度。设计了几种测量锥孔大端直径的方法,实用性强,测量精度高。

There was large detection errors in measuring the big end of tapered bore size by using a common measuring tool, for parts with small dimensional tolerance, the measurement accuracy could not be met by the method. Several measurement methods were designed for tapered bore large end diameter. The methods are practical with high precision.
