随着汽车变速齿轮的精度要求的不断提高,与其相应的制造工艺、工装也在不断创新。介绍了一款在磨齿加工工序中,利用账力心轴夹具夹紧行程小这一特征,对账力心轴夹具的弹簧套与刚性心轴的工作锥度进行了创新型的改进,使原来弹簧套工作时,撑紧工件内孔的弹性夹紧力沿内孔轴向逐渐变化而趋于相等。由生产实践证实:使用该夹具进行工件定位,其定心精度大大提高,保证了齿轮磨齿加工后的高精度;工件的装夹方便、快捷,提高了生产效率,并有利于工件装夹实现自动化。
With the continuous improvement of the precision of the gearbox of the car, its corresponding manufacturing technology and tooling are constantly innovating. Introduced a grinding process in the process, the use of the account of the mandrel mandrel jaw clamping the small stroke this feature, the mandrel on the strength of the mandrel and rigid mandrel work taper innovation has been improved so that the original When the spring sleeve is working, the elastic clamping force for supporting the inner hole of the workpiece gradually changes along the axial direction of the bore and tends to be equal. Confirmed by the production practice: the use of the fixture for workpiece positioning, the centering accuracy is greatly improved to ensure that the gear after grinding high precision; workpiece clamping convenient and quick, improve production efficiency, and is conducive to the workpiece clamping to achieve automation.
