Beneficial effect：
By the present invention in that measurement system error, confirmatory measurement ability GRR can be eliminated completely with steel band type inner bore checking fixture
＜ 10% can receive, and measurement efficiency is also improved significantly；The replaceable design of different internal diameters, the steel band length to have converted, match somebody with somebody
Start to measure work by adjusting can with corresponding calibrating device；Operating efficiency improves than traditional inside meter metering system
More than 1.5 times, measurement is accurate.
The setting of spring helps the reset of two levers, and the state for making measurement in the raw, ensures the accurate of size
Property.
The setting of centering cover plate not only protects base to be also prevented from the interference of steel band, is measured also for guarantee accurate
Property.
Using flexible steel band δ 0.4mm technical know-hows good with measured piece aperture stickiness under levers support effect, lead to
Lever transmission ratio is crossed to control the stability of measurement result, uniformity, while outfit standard exemplar（I.e.：Calibrating device）Come carry out pair
Than measurement, systematic error is eliminated.
The use of connecting plate makes whole cubing form an entirety, adds reliability.
The ring gear that the present invention can measure different pore size is only need to change accessory can be achieved with, and measurement stability is good, due to
It can accomplish " a tractor serves several purposes ".
