用正弦规测量圆锥锥度时,为了测量正确,往往需要用锥度靠铁来使圆锥的轴线与正弦规平行。所以,对平时常用的锥度总是需要备有靠铁。但如果测量不常用的锥度,由于不备有靠铁,测量时就比较困难。这里,向大家介绍一种不用靠铁的测量圆锥的方法,见图示。测量时,将正弦规靠平角铁,同时,工件的左侧母线也靠平角铁,如设被测圆锥锥角 When measuring conical taper with a sine gauge, it is often necessary to use a taper iron to make the axis of the cone parallel to the sine gauge for correct measurement. Therefore, the usual commonly used taper is always required by the rail. However, if the measurement is not commonly used taper, due to the lack of access to the iron, the measurement is more difficult. Here, to introduce a method of measuring the cone without the iron, as shown. Measurement, the sine will depend on the angle of iron, while the workpiece on the left side of the bus also by the angle of iron, if the cone cone angle
