(1)图1:带箭头的指引线不应将被测要素与公差框格的两端相连。 (2)图2:该轴线的公差形状是一个圆柱体,所以在公差值前应加一个“φ”. (3)图3: (a)基准代号连线应与φ60h7尺寸线对齐,而同轴度公差的基准应指轴线。 (b)同轴度的公差带是圆柱公差带,故在公差值前应加φ,不是R。 (4)图4:圆度形位公差的标注方法与斜跳动的标注方法不一致,指引线应分别标注。
(1) Figure 1: Guidelines with arrows The elements to be measured should not be connected to both ends of a tolerance grid. (2) Figure 2: Tolerance of this axis is a cylinder, so a “φ” should be added before the tolerance. (3) Figure 3: (a) The datum code connection should be aligned with the φ60h7 dimension line, The criterion of concentricity tolerance should refer to the axis. (b) The concentricity tolerance band is a cylindrical tolerance band, so φ should be added before the tolerance and not R. (4) Fig. 4: The marking method of the tolerance of the circularity shape position is inconsistent with the marking method of the oblique beating. The leading lines should be marked separately.
