Description
Technical field
The present invention relates to deep hole field, and in particular to be easy to measure a kind of device 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.
The content of the invention
The technical problems to be solved by the invention are that existing measurement deep hole internal diameter is more inconvenient, troublesome poeration, purpose
It is that a kind of device for being easy to measure deep hole internal diameter is provided, solves the problems, such as that deep hole internal diameter is inconvenient to measure.
The present invention is achieved through the following technical solutions：
It is easy to measure a kind of device of deep hole internal diameter, including measurement apparatus body, the lower section of the measurement apparatus body is
Conveyer belt, is connected with connecting rod on the conveyer belt, the lower end of the connecting rod is connected with expansion link, four of the expansion link
Side is connected to an eddy current displacement sensor, and the expansion link is connected with infrared sensing on two relative sides
Device, the conveyer belt drives connecting rod movement, and four eddy current displacement sensors are in same level.
Further, when deep hole internal diameter measurement is carried out using the present apparatus, measurement apparatus body is placed on the upper of deep hole
Side, conveyer belt drives attachment means movement, and mobile device drives expansion link to be moved left and right, is now connected to expansion link side
On infrared sensor be used to sense the position of deep hole, after infrared sensor senses the position of deep hole, conveyer belt stops passing
Send, and then expansion link is located at the top of deep hole, now, expansion link extends still further below, and then stretches into deep hole, after stretching into, even
The eddy current displacement sensor being connected on expansion link side starts to measure it to the distance of deep hole internal diameter, then by measure
To computing module, computing module is by the data measured by two relative eddy current displacement sensors, and two for data is activation
The distance between eddy current displacement sensor is added, and obtains a data, and two groups of data are obtained in the present apparatus, finally takes two
The average value of data, the i.e. size of institute's sounding hole internal diameter.
Specifically, being easy to measure a kind of device of deep hole internal diameter, it is connected with the measurement apparatus body for controlling to open
Open or terminate the control button of measurement.When control button is pressed, infrared sensor is started working, and conveyer belt starts to pass
Send, it is known that expansion link is located at the top of deep hole, conveyer belt stops transmission.After measurement is finished, control button is pressed again, pass
Send band that attachment means are sent back into home position, and expansion link shortens go back to home position.
Preferably, it is easy to measure a kind of device of deep hole internal diameter, is connected with the measurement apparatus body for showing survey
Measure the display screen of result.Measurement result directly shows that so operation more facilitates on a display screen, is easy to read.
Preferably, it is easy to measure a kind of device of deep hole internal diameter, tripod is connected with below the measurement apparatus body.
The tripod is used to be supported measurement apparatus body, more consolidates, and is easy to operation.
Preferably, it is easy to measure a kind of device of deep hole internal diameter, there are wear-resistant coating and corrosion resistant in the surface of the expansion link
Erosion resisting coating.Wear-resistant coating and corrosion-resistant finishes can effectively increase the service life of expansion link, and this sample measurement apparatus also can be effective
Growth service life.
The present invention compared with prior art, has the following advantages and advantages：
1st, the present invention be easy to measure deep hole internal diameter a kind of device, the present apparatus measure internal diameter when, place measurement apparatus when,
Need not be aligned with, the present apparatus automatically can be alignd expansion link and deep hole by infrared sensor, using more fast and easy,
So people avoid the need for oneself by it to it when in use, therefore the present apparatus is more convenient in measurement；
2nd, the present invention be easy to measure deep hole internal diameter a kind of device, the present apparatus measure internal diameter size when, 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 a kind of device of deep hole internal diameter, and the present apparatus obtains two data in measurement, takes it and puts down
Average, therefore measurement is more accurately and reliably, and the present apparatus is easy to operate, and it is in hgher efficiency.
