用机械式量仪检查表面不直度时,测量不直度偏差一般是按ΓОСТ 10356—63附录2所举的例子进行的。被检查的剖面规定为平行于校验平板的平面。按照测量表头的示值,可以划出剖面的轮廓图或确定直度的最大偏差量,测量表头是沿平板在专用支架上移动的。在检查不直度的携带式专用仪器中,平板的作用由一个或两个校验直尺来实现。携带测量表头的滑板移动时,校验直尺同时起导轨作用。这类
When using a mechanical measuring instrument to check the surface is not straightness, the measurement of the deviation is generally measured according to ΓОСТ 10356-63 appendix 2 examples. The section under inspection is defined as parallel to the plane of the inspection plate. According to the meter head indication, you can draw the outline of the profile or determine the maximum deviation of the straightness, the measuring head is along the plate in a special bracket to move. In the inspection of non-straight portable special equipment, the role of the plate by one or two check ruler to achieve. Carrying the measuring head to move the slider, check the ruler at the same time from the role of guide. This class
