【摘要】：为了提高数控插齿机插削斜齿精度,提出了一种基于试切误差补偿的数控加工方法。首先,在分析斜齿螺旋线偏差产生机理的基础上,采用线段逼近理论主运动曲线,计算满足加工精度要求的线段最大许用步长和曲柄转角;然后,通过试切齿轮,测取螺旋线偏差并反求出主运动曲线偏差,获得更准确的新理论主运动曲线;最后,在生产用G代码中,重新用线段逼近新理论主运动曲线。实验结果表明:加工的斜齿轮螺旋线偏差达到7级精度,结果符合预期,验证了技术方案的可行性。
[Abstract]:In order to improve the precision of slotting in NC gear shaper, a NC machining method based on trial-cutting error compensation is proposed. First of all, on the basis of analyzing the mechanism of helical deviation of oblique teeth, the line segment is used to approximate the theoretical main motion curve to calculate the maximum allowable step length and crank rotation angle of the line segment which meets the requirements of machining accuracy. The deviation of spiral line is measured and the deviation of main motion curve is obtained, and a more accurate principal motion curve of new theory is obtained. Finally, in the G code for production, the line segment is reused to approximate the new main motion curve of theory. The experimental results show that the helical deviation of the helical gear is up to 7 degrees of accuracy, and the results are in line with the expectation, which verifies the feasibility of the technical scheme.
