AI Technical Summary

Technical Problem

In the prior art, in the grinding process of synchronizer steel ring products, the accuracy control is poor, the workpiece structure is thin and easy to deform, resulting in a deterioration of the shape and position tolerance.

Method used

A high-precision synchronous ring conical surface grinding clamp is designed, using components such as inner cone grinding sleeve, inner cone grinding positioning mandrel, grinding positioning mandrel jacket and cylinder. By pressing the end surface, positioning and floating centering are avoided by the impact of gap fit and the difference between the machine tool spindle and the tool center.

Benefits of technology

It effectively improves the machining accuracy of the workpiece, avoids deterioration of the accuracy caused by deformation and rebound, and ensures high accuracy of synchronous ring cone surface grinding.

Abstract

The invention provides a high-precision synchronous ring conical surface grinding fixture which is characterized in that an inner cone grinding sleeve connecting disc is connected with an inner cone grinding sleeve bolt, a conical grinding surface at the lower part of an inner cone grinding sleeve is connected with a conical surface of a synchronous ring, and a protective plate is mounted above an inner cone grinding positioning mandrel; the interior of the plane needle bearing penetrates through the air cylinder to be arranged between the inner cone grinding and positioning mandrel and the grinding and positioning mandrel outer sleeve, the grinding and positioning mandrel outer sleeve and the grinding and positioning mandrel outer sleeve base are installed under the machine tool spindle after being assembled, and an inner hole of the grinding and positioning mandrel outer sleeve and the machine tool spindle are concentric and locked; the locking pull rod adjusts the strength of the pressing plate for pressing the synchronous ring, the synchronous ring is fixed between the pressing plate and the inner cone grinding and positioning mandrel, and molybdenum spraying treatment is conducted on the outer conical surface of the synchronous ring. According to the high-precision synchronous ring conical surface grinding fixture, an end face pressing and positioning tool is provided, the center of a workpiece is centered in a floating mode, and the machining influence caused by clearance fit and non-concentricity of the center of a machine tool spindle and the center of the tool is effectively avoided.
