孔轴共存型工件的测量新方法及自动化测量系统

A New Method for Measuring Hole shaft coexisted Parts and Its Automatic Measuring System

介绍了测量孔轴共存型工件的激励动态位置跟踪测量法及其自动化测量系统。该方法通过工件在测量夹具内的运动测得几个特殊位置参数，从而可计算出工件的孔径、轴径和中心距，具有测量精度高、速度快、成本低等优点。

A stimulating dynamic position trace method for measuring hole shaft coexisted parts and an automatic measuring system based on this method are introduced Using the method, a few special position parameters of part moving in a jig can be gained, then measuring results can be obtained by dynamic analysis and calculation The measuring system possesses many advatages, such as high accuracy, high measuring rate, low cost
