Based on Thin-Wall Gear Turning Jig Design and Application
In the actual processing of thin-walled gears encountered in the processing of turner end face parallelism exceeds the problem,processing,if the CNC lathe hydraulic power chuck clamping cylindrical machining,the jaws clamping force makes the thin-walled gear end face slight deformation,resulting in turning the thin-walled gear end face parallelism deviation,the process capability is unstable,there is a phenomenon of over the upper limit occurs,resulting in the size of the unqualified.After statistical analysis,the gear endface parallelism process capability CPK value of the highest 0.97,lower than the target value of 1.67.Through the analysis of man,machine,material and method of each ring,it was found that the positioning surface of the machine tool in contact with the thin-walled gears and the clamping force is the most important factor of the size of the parallelism of the endface.Therefore,there is an urgent need to improve the existing machining method,design a set of thin-walled gear turning fixture,which can ensure the parallelism of the end face of thin-walled gears,but also convenient for operators to use.
