【摘要】 目前对于普通螺纹规中径的校准方法有很多,比如三针法、影像法、轴切法、侧规法和环规法等等。而对于一些大尺寸的特殊螺纹规(如锯齿形螺纹规)没有统一的方法,该文对这类特殊螺纹规的中径校准提出了一种切实可行的解决办法,并且在实际应用中得到了验证。更多还原

【Abstract】 Currently,there exist many calibration methods for pitch diameter of common thread gauge,such as the three-needle method,image method,axis cutting method,the side-lay method and the ring method and so on.However,there is no uniform method for some largesize special thread gauge(e.g.serrated thread gauge).This paper presents a practical solution for such pitch diameter calibration of special thread gauge,which has been veri?ed in practical application.更多还原
