我厂过去制造的凸輪升高量均小于10毫米,可以用百分表和分度头来进行檢定。58年生产C8950和C8955型铲床的凸輪、它的升高量多数是大于10毫米。如图1为导程22毫米的凸輪(最大导程为45毫米),因此就不能再用百分表檢定(由于百分表測量范圍所限)。經过同志們的研究,做出图二所示的底座(其尺寸是按德国蔡司厂的分度头工作台設計的),用螺釘和螺帽及压板紧固在分度头工作台上,然后将臥式阿貝测长仪头装在底座上面即可进行测量工作。
I plant in the past to create the amount of increase in the cam are less than 10 mm, you can dial gauge and sub-head for testing. 58 years The cams for the C8950 and C8955 shovel beds are mostly raised by more than 10 millimeters. As shown in Figure 1, a lead 22mm cam with a maximum lead of 45mm can no longer be calibrated with a dial indicator (due to the dial gauge range). After comrades to make the base shown in Figure II (its size is according to Germany Zeiss plant division head table design), with screws and nuts and platen fastened in the indexing table, Then the horizontal Abbe length measuring instrument head mounted on the base above the measurement work.
