Abstract

The invention provides a positioning device for turning of an inner hole of a copper bush and relates to the field of machinery positioning devices. The copper bush is effectively protected while being turned, so that the copper bush is prevented from being damaged. According to the technical scheme, the positioning device comprises a positioning shaft and a nut, wherein one end of the positioning shaft is a copper bush positioning end and the other end of the positioning shaft is a machine tool clamping end; the copper bush positioning end is provided with a stepped hole for positioning the outer circle and end surface of the copper bush, and the outer side surface of the copper bush positioning end is provided with an external thread; an inner hole of the nut is a stepped through hole, a large-diameter hole of the stepped through hole is a threaded hole matched with the external thread of the copper bush positioning end, and the diameter of a small-diameter hole of the stepped through hole is larger than the inner diameter of the copper bush but smaller than the external diameter of the copper bush.

Description

technical field [0001] The invention relates to the field of mechanical positioning devices, in particular to a positioning device for machining inner holes of copper sleeves. Background technique [0002] The copper sleeve of the product in the factory is a copper tubular part, which is mainly used for important hole-shaft fits, where the inner surface of the hole and the outer circle of the shaft are damaged, and the cost of replacing parts is high. The copper sleeve is easy to replace after wear and tear, and the maintenance cost is low. The outer circle and inner hole of the copper sleeve are all finished surfaces, which have higher tolerance requirements and surface roughness requirements. The processing sequence of the copper sleeve is generally to process the outer circle first, and then process the inner hole. Because the thickness of the copper sleeve is generally a few millimeters and the copper is soft, the outer circle of the copper sleeve cannot be directly cl...
