我们制成的莫氏4~#锥孔检具(以下简称检具)实际上是用钢球测量圆锥孔角度法的发展,检具结构如图所示。检具按被测锥孔小端的直径选用小测球直径;大测球直径可按两球心距为50mm 来选取。使用时,松开表杆2的紧固螺母7,表杆2在弹簧8的作用下向下方移动,使检具大、小测球3和1的中心距达到最大。把检具放入 We made the Morse 4 ~ # taper pin gage (hereinafter referred to as gage) is actually the use of steel ball cone angle measurement method of development, gage structure shown in Figure. Check the diameter of the tapered end of the small end of the test using a small ball diameter test; big ball diameter by two ball center distance of 50mm to select. When in use, loosen the fastening nut 7 of the rod 2, and the rod 2 moves downward under the action of the spring 8, so that the gauge is large and the center distance of the small measuring balls 3 and 1 is maximized. Put the gage into it
