Abstract

The invention discloses a thread machining positioning device for a transmission shaft, which is convenient for performing thread machining on the small tip end of the transmission shaft. The device is used for machining the threads on the small tip end of the transmission shaft and comprises a base capable of being fixed on a machine table; a clamp body is detachably positioned on the base; a first positioning block matched with a first positioning hole of the base is arranged at the bottom of the clamp body; a cylindrical die core is detachably positioned on the clamp body and is arranged in a second positioning hole of the clamp body; a third positioning block matched with a third positioning hole in the clamp body is arranged at the bottom of the die core; the third positioning hole is penetrated by the first positioning block and is communicated with the second positioning hole; two key slots matched with two reinforcing ribs at the inner hole at the large tip end of the transmission shaft are arranged on the die core; a fourth positioning round boss is arranged at the inner wall of the third positioning hole of the clamp body; the side wall of the fourth positioning round boss is matched with the excircle of the large tip end of the transmission shaft.

Description

technical field [0001] The invention relates to the technical field of transmission shaft assembly, in particular to a positioning device for thread processing of a transmission shaft. Background technique [0002] In the field of transmission shaft assembly technology, it is necessary to thread the small end of the transmission shaft so that the nut can be tightened at this end when the transmission shaft is assembled as a whole. Due to the difficulty in the overall positioning of the transmission shaft, the traditional way of threading the end is basically to use the artificial threaded drill sleeve axle head thread. In this way, due to the operator's subjectivity and human uncertain factors, the angle of the threaded thread Can not meet the design requirements. Contents of the invention [0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention aims to provide a transmission shaft thread processing and positioning device. By accurately ...
