AI Technical Summary

Technical Problem

When grinding the end face of existing gears, there are problems such as inconsistent clamping and positioning and gear slippage, which leads to extended processing cycles and unstable grinding quality.

Method used

The gear end face grinding fixture consists of a spindle, a backing plate, a tensioning sleeve, a lever, and a limiting mechanism. It uses the outer wall of the gear as a reference surface for positioning, fixes the gear with a tensioning sleeve, and sets a limiting mechanism to prevent slippage, reduce the contact area to prevent adsorption, and simplify the operation process.

Benefits of technology

It achieves stable positioning and synchronous rotation of the gear end face, improves production efficiency, ensures processing quality and ease of operation, and simplifies the processing procedure.

Abstract

This utility model discloses a gear end face grinding fixture, including a spindle supported on both sides by centers and mounted on a grinding machine, a backing plate mounted on the spindle, an adjustable tension sleeve mounted on the spindle, a detachable lever mounted on one side of the spindle, and a limiting mechanism mounted on the other side of the spindle to prevent parts from falling off. Multiple through holes are provided along the circumferential direction on the outer wall of the backing plate, and a positioning mechanism for auxiliary gear placement is detachably mounted on one side of the backing plate. This utility model uses the backing plate as a reference surface for gear placement, and the tension sleeve supports and fixes the gear, while the positioning mechanism helps prevent gear slippage during machining. The limiting mechanism prevents parts from falling off, effectively ensuring the integrity of the fixture. The through holes and grooves on the backing plate reduce the contact area with the outer wall of the gear, avoiding machining adhesion, resulting in a simple and compact structure.
