一般的圆度仪,除了测量零件的不圆度、端面与轴线的不垂直度、轴线与轴线的不共轴度、平面之间不平行度等外,能不能测量零件的直径或曲率半径呢?我们在实际测量中认为是可以的。对于那些较难测量的局部球面,例如球窝的测量,通过圆度仪测量可以达到很高的测量精度。圆度仪大致有测头回转和工作台回转二种,我国现有的圆度仪大部分是属于测头回转的这类,下面介绍在这类圆度仪测量孔径、球窝曲率半径的情况:
General roundness instrument, in addition to measuring the non-circularity of the part, the end face and the axis of the non-perpendicularity, the axis and the axis of the non-coaxiality, the plane between the non-parallelism, etc., can measure the diameter of the part or radius of curvature We think in the actual measurement is possible. For those difficult to measure the local sphere, such as ball and socket measurements, measured by the roundness meter can achieve high measurement accuracy. Roundness roughly the probe rotation and table rotation two kinds, the majority of our existing circularity is the type of probe rotation, the following describes the measurement of such roundness instrument diameter, ball and socket radius of curvature of the situation :
