我厂机床产品中,锥销与锥销孔相配合件很多,要保证机床装配定位精度,锥销与锥销孔的接触面要求达到70%。为满足这种要求,需要采用锥销环规来保证锥销与销孔铰刀的互换性。过去我们应用铸铁锥销环规。这种环规在制造中是以铰刀和锥度棒加工来控制孔的精度,同时这种环规易于磨损,每个月就得消耗五把以上。后来,我们选用淬硬(R_C60～64)轴承钢制做锥销环规(图2示),并以环氧树脂研磨棒(图1示)加工环规深
I plant machine tool products, cone pin and cone pin hole with a lot of parts, to ensure that the positioning accuracy of the machine tool assembly, tapered pin and cone pin hole contact surface requirements of 70%. In order to meet this requirement, it is necessary to adopt a conical pin ring gauge to ensure interchangeability between the conical pin and the pin hole reamer. In the past we used cast iron cone ring ring gauge. This ring gauge is manufactured in the reamer and tapered rod processing to control the accuracy of the hole, at the same time this ring is easy to wear, you have to consume more than five months. Later, we choose hardened (R_C60 ~ 64) bearing steel cone ring ring gauge (Figure 2), and the epoxy resin grinding rod (Figure 1) processing ring depth
