摘要
一种大型螺纹自动检测的方法采用了新型螺纹测头,其中包括TESA电感传感器和测针,测针按螺纹牙型选择。测量方法基于螺纹综合测量原理,采用接触式测量方式。通过试验分析完成了螺纹作用中径数值的检测。通过频谱分析,对螺纹作用中径数值测试的动态误差进行了剔除并且得到了相关信息。检测方式的测量力远小于用常规的螺纹量规检测的测量力从而解决了接触应力引起薄壁管件测量误差的问题,试验表明这种新型螺纹测头能够提高测量精度,经过数据处理测头测量精度达到1μm。
A new method for automatically detecting the large screw thread is discussed by using the neotype gauge head of thread which includes TESA inductance type transducer and survey probe chosen according to the tooth-type of thread. The way of contact measurement is adopted on the basis of the synthetically measuring principle for thread. The functional diameter of thread is investigated and analyzed experimentally. Through spectrum analysis, the dynamic error is picked out while data of functional diameter of thread will be obtained. Because the measurement strength of the neotype gauge head is much smaller than that of the regular screw gauge so as to diminish the most measurement error resulted from the contact stress. Experimental results show that the neotype gauge head of thread can improve measuring accuracy and the measuring accuracy reaches 1um after data processing.
