利用锥面母线测量锥度的方法研究

摘要

传统的测量锥度的方法是测出大、小端直径之差和圆锥长度,再由函数式求出锥度.采用该方法需要测量3个参数.利用锥面母线检测锥度的方法是任取一段圆锥面的母线作1个直角三角形,根据2个直角边的长度求锥度,通过转动螺母滑块带着测量头沿母线移动,滑块旁的2块千分表同时显示出2个直角边的数值,再根据斜角α的正切函数求出锥度.采用该方法只需测量2个参数,不用测量圆锥大小端的直径,减小了测量误差,能够直观、快捷地求出锥面的锥度.%The method of measuring the taper is to measure the difference of the diameter of the large and small end,the taper length of the cone,and then the taper according to the function formula.This method needs to measure three parame-ters.Adopting the new method is to take a bus for a right angled triangle cone surface,and to get the taper according to the length of two right angles.Turn the nut slider with a measuring head move along the bus,and the slider at the side of two pieces of dial indicator shows two square edge value at the same time.According to tangent function the busbar taper is a-chieved.This test method requires only two parameters,not measuring the diameter of the cone size,reducing the measure-ment error,and getting the taper of the cone directly and quickly.
