我厂为美商生产的曲轴为四缸90°分度曲轴,对于该曲轴的分度误差,我们设计了90°分度检具(见图1)进行检测。1.检测用具检测用到90°分度检具、带杠杆百分表的高度游标卡尺、外径千分尺、等高V形铁及0级检验平台。2.检测方法检测方法,如图2所示。(1)将曲轴第1、5主轴颈架在等高V形铁上, The crankshaft produced by our company is a four-cylinder 90 ° indexing crankshaft. For the indexing error of the crankshaft, we designed a 90 ° indexing gauge (see Figure 1) for testing. 1. Testing equipment used to detect 90 ° indexing gage, with a high degree of vernier caliper caliper, micrometer diameter, contour V-shaped iron and 0 test platform. 2. Detection method detection method, shown in Figure 2. (1) the crankshaft No. 1,5 spindle neck frame in the contour V-shaped iron,
