2.线对面间的垂直度误差检测方法直角尺检测法。测量被测零件孔的轴线对上表面垂直度误差,先将被测孔内插入心轴,取直角尺放到基准表面上,并在给定方向上与心轴素线接触,测得l_2长度范围内两者之间最大间隙A。若被测孔长为l_1,则其垂直度误差应为:f=L/l_2A。需测量任意方向上垂直度误差时,可将直角尺沿心轴周向多个方向分别进行测量,取其中最大值作为该零件的垂直
2. The line between the square of the vertical error detection method square ruler detection method. Measure the vertical axis error of the hole to the surface of the part under test. Insert the mandrel into the hole to be measured first, place the square on the reference surface and make contact with the mandrel line in the given direction. The length of l_2 The maximum gap A between the two. If the measured hole length l_1, its verticality error should be: f = L / l_2A. To measure the degree of verticality error in any direction, the square can be measured along the circumference of the mandrel in multiple directions were measured, whichever is the maximum as the vertical
