【摘要】：基于圆柱坐标系测量原理,采用电子展成法研制了一台环面蜗轮滚刀测量机用于环面蜗轮滚刀的快速测量。该测量机通过对3个运动轴的闭环控制,使测头沿着被测误差项的路径运动来获取数据并完成测量。介绍了测量机的工作原理与构成,其为卧式结构,由花岗石床身、精密密珠主轴、滑动导轨和闭环控制系统构成。开发了环面蜗轮滚刀测量软件,实现了环面滚刀各项误差的快速精密测量。实验显示:该仪器可以对切削刃螺旋线误差、刃口齿形误差和容屑槽周节误差进行测量,测量的合成不确定度分别为2.35、2.45和2.94μm,均小于圆柱齿轮滚刀标准GB/T6084-2001中对应误差项公差的1/3,满足AA级精度的环面滚刀各项误差的测量要求,验证了该测量机的功能与可靠性。该测量机也可以用于环面蜗杆、圆柱蜗杆及圆柱滚刀的测量。
[Abstract]:Based on the measuring principle of cylindrical coordinate system, a measuring machine of toroidal worm wheel hob is developed by using electronic spread method for rapid measurement of ring worm gear hob. Through the closed-loop control of the three moving axes, the probe moves along the path of the measured error term to obtain the data and complete the measurement. This paper introduces the working principle and structure of the measuring machine, which is a horizontal structure, which is composed of granite bed, precision bead spindle, sliding guide rail and closed loop control system. The measuring software of toroidal worm gear hob is developed, and the error measurement of toroidal hob is realized quickly and accurately. The experimental results show that this instrument can measure the helix error of cutting edge, the tooth shape error of cutting edge and the error of chip holding groove circumscribed joint. The measurement uncertainty is 2.35 ~ 2.45 渭 m and 2.94 渭 m respectively, which is less than 1 / 3 of the tolerance of the error term in the standard GB/T6084-2001 of cylindrical gear hob. It meets the measurement requirements of the error of the ring hob with AA accuracy, and verifies the function and reliability of the measuring machine. The measuring machine can also be used for measuring toroidal worm, cylindrical worm and cylindrical hob.
