图示检测仪用来检验齿条齿面母线相对于零件(顶针套)轴心线的垂直度,它由带支杆2的V形块3,用螺钉4固定的指示器5和标准样件1组成。为了确定不垂直度的大小,将V形块放在被检验零件表面上,直至支杆与装在零件齿上的标准样件接触,把指示器调到零,然后从标准样件的另一面放上V形块使之与支杆接触。指示器的读数差值即等于齿相对顶针
The graph tester is used to check the perpendicularity of the rack tooth surface busbar with respect to the axis of the part (thimble sleeve). It consists of the V-shaped block 3 with strut 2, the indicator 5 fixed with screw 4 and the standard sample 1 composition. In order to determine the size of the non-perpendicularity, place the V-shaped block on the surface of the part to be inspected until the struts come into contact with the standard parts mounted on the teeth of the part, set the indicator to zero, and then from the other side of the standard part Put the V-shaped block into contact with the strut. The difference between the readings of the indicator is equal to the tooth relative to the thimble
