AI Technical Summary

Technical Problem

In the existing technology, the machining accuracy of sector gear shafts is low, and traditional forming grinding wheels cannot meet the industrial precision requirements. Furthermore, multiple clamping operations lead to a decrease in repeatability and clamping accuracy, resulting in low machining efficiency.

Method used

Design a modular grinding wheel, including two edge-tooth grinding wheels and multiple intermediate-tooth grinding wheels, which are connected by bolts to integrate the tooth surfaces of different profiles of the sector gear shaft. All tooth surfaces can be ground in a single clamping operation. The profile position can be adjusted by profile offset simulation and axial feed dressing to improve accuracy.

Benefits of technology

It improves the machining efficiency and precision of sector gear shafts, avoids the drawback of traditional grinding wheels being unable to complete the machining of all tooth surfaces, and makes the process more controllable and more precise.

Abstract

The present application relates to the technical field of electroplated grinding wheel, in particular to a combined grinding wheel for grinding fan gear shaft and a manufacturing method thereof, which solves the problem of low machining precision of the grinding wheel on the fan gear shaft in the prior art, and the combined grinding wheel comprises two oppositely arranged edge tooth grinding wheels, the two edge tooth grinding wheels are detachably connected, a plurality of side-by-side arranged intermediate tooth grinding wheels are arranged between the two edge tooth grinding wheels, and the edge tooth grinding wheel and the intermediate tooth grinding wheel are coaxially arranged. The beneficial effect is that the combined grinding wheel integrates the tooth surfaces with different profiles on the fan gear shaft into a set of combined grinding wheel, and when the combined grinding wheel grinds the tooth surface of the fan gear shaft, the grinding wheel only needs to be clamped once, and then the grinding of the whole tooth surface of the fan gear shaft can be completed through the rotation and displacement of the fan gear shaft workpiece, thereby improving the machining efficiency and machining precision of the fan gear shaft.
