箱体主轴孔不同轴度的形式,属于孔对孔的不同轴度。按其测量方法大体上有打表法、瞄靶法、影象法和专用量规检查法。我厂经常使用的测量方法是回转打表法,其它方法用的不多。回转打表法(图1),是把被测箱体直立在平台的垫铁(四块)上,上下孔内装上检套,然后,检查孔内装上直径为60、长为1400的检棒,检棒下端顶尖孔内放一钢球(防止检棒上下窜动),检棒装上特殊表架(可上下移动,并能紧固在某一位置), Axis box shaft axis of the form of different degrees, are different from the hole on the hole axis. According to its measurement methods in general have hit the table method, aiming method, imaging method and special gauge test method. I often plant measurement method is rotary table playing method, the other methods used less. Rotary hit the table method (Figure 1), is to be measured on the erection of the box horn (four), the upper and lower holes fitted with jumpers, and then check the hole with a diameter of 60, length of 1400 dipstick , Check the bottom of the tip hole put a ball (to prevent the check bar up and down the movement), fitted with a special rod holder (which can move up and down, and can be fastened in a certain position),
