插齿刀凸曲前刀面加工对刀方法研究

摘要

插齿刀凸曲前刀面磨削加工中,砂轮的初始位置直接影响插齿刀凸曲面的加工精度及齿形精度.采用对射型激光传感器设计了对刀方案,并设计制造了对刀装置,用于确定插齿刀凸曲面加工时砂轮相对于插齿刀的初始磨削位置.应用对刀装置进行了对刀实验,实验结果验证了对刀方案的可行性.应用加工的插齿刀进行了齿轮插齿实验,齿轮的检测结果表明,所设计的对刀装置能够满足插齿刀凸曲面加工需求.%As for NC machining of convex curved rake face of a pinion cutter,the original position of grinding wheel is very important for the machining precision and tooth profile precision. Herein, tool presetting scheme was designed by using laser sensor,the tool presetting device was designed and manufactured,the original position of grinding wheel could be ascertained by using the device. The tool presetting experiments were done,the results of tool presetting experiments testify the feasibility of the scheme,gear shaping experiments were done also,and the results of gear shaping show that the tool presetting device can satisfy the demands of the manufacturing of pinion cutter with convex curved rake face.
