Standard is that the dress measurement big hole of body three is successfully crucial.At present, the measurement body Large Aperture Inner Diameter thousand that type of industry generally uses
It is bad or can not meet product measurement request, influence measurement body large aperture frock operability to be all present in point chi calibration tool
The operating efficiency of inside micrometer calibration and the precision of calibration.For case above, by the survey of the big hole of diesel-engine body three
Amount is divided by the use of the calibration of Large Aperture Inner Diameter micrometer as breach, design specialized calibrating installation in measurement body Large Aperture Inner Diameter thousand
To calibrate during chi, and it is successfully applied to the various measurement Large Aperture Inner Diameters thousand similar to the various big hole of diesel-engine body three
Divide in the calibration of chi.
The internal diameter during calibration of measurement Large Aperture Inner Diameter micrometer after the big hole of body three that this patent proposes processes
Micrometer device, and the calibration method of measurement Large Aperture Inner Diameter micrometer and special dress after the big hole of body three is processed
Put in the specific calibration example for applying to the measurement after three big holes process, measuring front large hole footpath inside micrometer, to realize
The big hole of body three process after measurement and measurement front large hole footpath inside micrometer calibration.Special purpose device user
Just, it is simple in construction, making easy to process, measurement large aperture after the various big hole of diesel-engine body three processes can be effectively improved
The operability and calibration efficiency that inside micrometer is calibrated during the calibration of inside micrometer, preferably ensure that diesel-engine body three
The technical requirements that measurement Large Aperture Inner Diameter micrometer is calibrated after big hole processes.
