It is known that so need to only set the value of θ, you can determine by the radius of mother rib lateral rotundum, can determine by the diameter of mother rib lateral rotundum, you can mark
Note scale 431.Here θ takes positive integer, you can takes 1 °, 2 °, 3 ° ... of θ successively value and then successively
Value, by these values successively mark as scale 431.When practical measurement, you can pass through the scale pointed by bidirectional pointer 9
431 position reads the size in aperture, the accuracy with science.
When needing measured hole center, the laser beam instrument 2 of 1 one end of Scale ruler is first turned on, adjusts plane
Light beam makes light gf be overlapped with the edge of measured workpiece, and when rotary laser frame for line marking instrument 3 is not alarmed, Scale ruler 1 is overturn to most
The as horizontality of Scale ruler 1 when at big corner, at this time the stroke by adjusting horizontal Scale ruler 1 find measurement
Zero c, the pointer 71 that the reading of hole center can be covered on 7 by ruler are read.When hole center to the edge of work away from
When from measurement range beyond Scale ruler 1, operator can be projected using rotary laser frame for line marking instrument 3 to measured workpiece surface
" ten " font light beam ab and cd is projected directly into as hole central datum line on tested tablet, and then operating personnel use
The ruler of other wide ranges carries out double measurement.
