在外圆磨床加工外圆锥工件时,通常采用正弦规和环规检测工件锥度。正弦规检测精度高,但工件不易固定,检测时间较长;用环规检测,需多次擦拭工件和涂色检查,并且不同直径和锥度的外圆锥工件需要各种不同的环规来检测。如果在加工中遇到工件较重,直径较大或无环规配磨外锥时,这两种检测方法有一定的局限性,使用不方便。例如,我厂加工的镗床刀杆6号莫氏锥柄、插齿机1:10锥度心轴、滚齿机1:20锥度心轴等,以前均采用停机配磨。每当磨制长短不同的同号锥度心轴时,必须多次到需要配磨心轴的机床涂色检查,反复试调工作台和试磨。这种加工方法效率低,并且影响正常生产秩序。以后虽然根据配磨的心轴制做了锥度环规,可是因环规较重,直径较大的工件装卸和测试困难,所以仍不能在保证工件精度条件下显著提高生产效率。
Cylindrical grinding machine cylindrical workpiece, the general use of sine and ring gauge workpiece taper. Sinusoidal detection of high precision, but the workpiece is not easy to fix, the detection time is longer; with the ring gauge, the workpiece to be wiped several times and color inspection, and different diameter and taper of the outer cone workpiece requires a variety of ring gauge to detect. If you encounter in the processing of heavier workpieces, larger diameter or ring-free grinding cone, the two detection methods have some limitations, the use of inconvenient. For example, my factory processing boring machine Arbor No. 6 Morse taper shaper, shaper 1:10 taper mandrel, hobbing machine 1:20 taper mandrel, before the stop-wear with the mill. Whenever grinding the same number of taper mandrels of different lengths, must be required to wear the mandrel with the machine color inspection, repeatedly test bench and try grinding. This method of processing is inefficient and affects the normal production order. Although after the system according to the mandrel with a taper ring system, but due to heavier ring, the larger the diameter of the workpiece handling and testing difficulties, it is still not in the conditions to ensure the accuracy of the workpiece significantly improve production efficiency.
