Description
Technical field
The present invention relates to deep hole field, and in particular to be easy to measure the measuring method of deep hole internal diameter.
Background technology
The field such as national defense and military, industrial production and scientific research device to hole internal diameter, the particularly survey of deep hole (depth is more than 3m) internal diameter
Amount has extensive demand, such as deep hole internal diameter measurement, the stone of hydraulic power system in the measurement of cannon internal diameter of the pipeline, engineering machinery
Oil probing pipeline inner diameter measurement, the inner diameter measurement of long pipeline etc. for Researches on Fluids.With the development of science and technology in deep hole
The measurement request more and more higher in footpath, if desired for the precision higher than 10 μm/50mm, and in processing site measurement.
Traditional longhole survey typically uses contact measurement method, is processed by deep hole aperture size first matched
Plug, then by plug and frock end face right angle setting, in sounding hole, is made frock end face and by depth measurement by plug insertion afterwards
Hole end surface is in close contact, the pointer meter reading that reading is connected with frock, then is obtained by sounding hole perpendicularity by geometry conversion.
When by the aperture very little or hole depth chin-deep of sounding hole, the manufacture of plug will be extremely difficult, and its cost will be greatly improved.This
Outward, contact type measurement can all have abrasion to deep hole inner surface and plug, and plug its certainty of measurement of once wearing and tearing will be difficult to ensure that；Separately
Outward, prior art also has using the method for three-dimensional coordinates measurement, but needs large-scale three-coordinates measuring machine, and cost is very high, and
Limited larger by site condition.

(3) four eddy current displacement sensors for being connected to expansion link side start to measure its distance for arriving inner walls of deep holes,
Four eddy current displacement sensors are relative two-by-two, and two straight lines corresponding to two groups of eddy current displacement sensors are mutual
Vertically；
(4) data is activation that eddy current displacement sensor will be measured is to computing module, and the computing module is relative by two
The data of eddy current displacement sensor and the diameter of expansion link be added, then two data that will be obtained average, finally
The data is activation that will be obtained is to controller；
(5) after controller obtains data, display screen is sent to, and show on a display screen.
It is easy to measure the measuring method of deep hole internal diameter, the infrared sensor is located at the side of expansion link.
It is easy to measure the measuring method of deep hole internal diameter, the expansion link is cylinder, and four current vortex displacements sensing
Device is on the cross section of expansion link.
It is easy to measure the measuring method of deep hole internal diameter, tripod is connected with below the measurement apparatus.
Further, when using the system, measurement apparatus are placed on the top of deep hole, the infrared sensor on controller
Position for sensing deep hole, when position is not found, controller control conveyer belt transmission, and then conveyer belt drives expansion link
It is mobile, when top of the expansion link in deep hole, controller control expansion link elongation, and then go deep into deep hole, it is connected to flexible
Four eddy current displacement sensors in bar side face, it is in alignment two-by-two, and two straight lines are mutually perpendicular to, four current vortexs positions
It is sent to pretreatment module by displacement sensor to the distance on inner walls of deep holes, and computing module is transferred data to after treatment, meter
Calculate module the diameter of the data of two relative eddy current displacement sensors and expansion link is added and, obtain two data,
Finally two data are averaged, last internal diameter is obtained, measurement result is sent to controller by computing module, and controller will
The size of internal diameter is sent to display screen, finally shows on a display screen.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention is easy to measure the measuring method of deep hole internal diameter, and the present invention is placing measurement apparatus when internal diameter is measured
When, it is not necessary to it is aligned with, the system automatically can align expansion link and deep hole, use more fast and easy；
2nd, the present invention is easy to measure the measuring method of deep hole internal diameter, of the invention when the size of internal diameter is measured, measurement apparatus
It is not in contact with the internal diameter of deep hole, therefore, it is possible to the damage being prevented effectively from during contact to inner walls of deep holes；
3rd, the present invention is easy to measure the measuring method of deep hole internal diameter, the present invention to obtain two data in measurement, takes it and puts down
Average, therefore measurement is more accurately and reliably, and the system is easy to operate, and it is in hgher efficiency.
