%X 针对螺纹联接时轴线位置的不确定导致的工件互换性不佳、可靠性降低、制造成本增加等不良后果，基于螺纹综合测量，提出一种全新的螺纹作用轴线测量方法。采用灵活的切片式刚性牙型测头，让其环绕螺纹测量并与之紧密旋合。TESA电感测头用于采集测头姿态数据，该数据反映被测螺纹的作用中径的变化。经过数据处理获得被测螺纹的作用中径线，结合已有螺纹轴线理论，拟合被测螺纹的作用轴线。实验结果验证了该测量方法实现的可能性，测量精度在10 μm内。介绍的测量方法弥补了现阶段螺纹测量领域内对螺纹轴线研究的不足。<br>Because of the uncertainty of the position of a functional axis of the thread while connecting threads, such as the low interconvertibility, low reliability, the increase of manufacturing cost, etc., a new method for measuring the functional axis of the thread is presented on the basis of the synthetic thread measurement principle. The flexible sliced tooth-type gauge head with high stiffness is adopted to encircle and engage with the thread tightly. The TESA inductance type transducer is used to measure the position change of the gauge head, which reflects changes in the functional diameter of the thread. Through processing data, the generalities of the functional diameter of the thread are obtained. With the existing theory of functional axis of thread, its functional axis are worked out. The experimental results verify the feasibility of the measurement method, with which the measurement accuracy is higher than 10 μm. The measurement method presented in this paper contributes to solving the deficiency of the current study of the functional axis of thread
