加工曲轴连杆轴颈时,需测量轴颈端面至曲轴端面的五个距离尺寸(见图),我厂采用过多种类型的卡板及测量工具,但效果均不理想。经多次改造,现用图示的测量工具且稍微移动量具,就可进行多种尺寸测量。该量具的构造及使用方法如下: 支承轴6是一空心棒料,上面固定五个检验柱销,柱销7左侧制成平面,各柱销平面到固定在轴6右端的档块14测量面间的距离正好等于曲轴上需要测量的距离尺寸。右V形块总成12通过圆柱销13与件6固定联接;左V形块总成V可在件6上滑动,借螺钉16压 When machining the crankshaft connecting rod journal, it is necessary to measure the five distance dimensions from the journal end face to the crankshaft end face (see photo). Our factory uses many types of pallets and measuring tools, but the results are not satisfactory. After many transformations, the current measurement tools used to illustrate and move the gauge a little, you can make a variety of size measurements. The measuring tool is constructed and used as follows: The supporting shaft 6 is a hollow bar material, on which five checking pins are fixed, the left side of the pin 7 is made into a plane, and the plane of each pin is measured to the stop 14 fixed on the right end of the shaft 6 The distance between faces is exactly equal to the distance dimension to be measured on the crankshaft. The right V-block assembly 12 is fixedly coupled to the member 6 by means of a cylindrical pin 13; the left V-block assembly V is slidable on the member 6 by means of a screw 16
