Abstract

The invention proposes a push-type expanding sleeve precision turning jig to solve the technical problem that the existing gear inner cavity end face positioning jig cannot be installed. Including flange plate, push rod, expansion sleeve positioning cone, adhesive expansion sleeve, multiple retraction springs, push sleeve, thread adjustment sleeve and multiple thread pins; the front end of the push rod extends into the center hole of the flange plate, and pushes The rear end of the rod protrudes from the big end of the flange; the small end of the positioning cone of the expansion sleeve is connected with the small end of the flange by bolts, and a plurality of external splines are arranged on the flange at the big end; the bonding The expansion sleeve is set on the positioning cone of the expansion sleeve; a plurality of retraction springs are set between the front surface of the bonding expansion sleeve and the rear end surface of the big end flange; the push sleeve is set on the small end of the flange, and the small end of the flange A waist-shaped hole extending axially is arranged on the side wall, and one end of the threaded pin passing through the waist-shaped hole is connected with the push sleeve, and the other end is connected with the front end of the push rod.

Description

technical field [0001] The invention relates to a turning fixture, in particular to a push-type expanding sleeve finish turning fixture. Background technique [0002] The processing technology of a certain gear part requires hot turning of the cone surface, inner hole and end face. Generally, the end face of one side of the gear is used to locate the axial dimension, and the spline hole is centered. However, the processing technology benchmark becomes the end face T of the gear inner cavity (see figure 1 ) and the spline hole, limited by the T size of the end face of the gear inner cavity, the existing positioning fixture cannot be installed, so a new fixture needs to be designed. Contents of the invention [0003] The purpose of the present invention is to solve the technical problem that the existing gear inner cavity end face positioning fixture cannot be installed, and to provide a push-type expanding sleeve finish turning fixture, which realizes the positioning of th...
