Abstract

The invention relates to a threaded shaft turning positioning device comprising a locating sleeve. The threaded shaft turning positioning device is characterized in that the locating sleeve comprises a clamping section and a tapered section, wherein the clamping section is provided with an internal thread, and the tapered excircle of the tapered section is provided with an external thread; elongated holes are arranged at the periphery between the clamping section and the tapered section, connection seams are arranged from the bottoms of the elongated holes to the end face of the tapered section, the width of each connection seam is from the periphery of the locating sleeve to the inner wall of a center hole of the locating sleeve, and the connection seams divide the locating sleeve into four parts from the bottoms of the elongated holes; and clamping nuts are arranged on the excircle of the tapered section 4. The threaded shaft turning positioning device disclosed by the invention is simple in structure, convenient to operate and high in positioning machining precision.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a positioning tool for turning a shaft with external threads. Background technique [0002] The threaded shaft refers to the shaft with external thread on the outer circumference.
