Cause the forfeiture of structure function, or even huge security incident can be caused.For spiral marking connection internal and external threads production detection and
Abrasion detection after use is to the peace of work all with indispensable effect.Measuring method is more also compares for externally threaded detection
Maturation, but the measurement China's manufacturing industry for internal thread is mainly still measured using contact type measurement method.Contact is surveyed
Amount easily causes attrition to measured workpiece.With the continuous development of computer technology so that Digital Image Processing, artificial intelligence
The subjects such as energy are constantly progressive, and this has just promoted industrial development.With the development of industrial technology, contactless measurement obtains extensively
General application.
For narration above, there is provided a kind of inexpensive and lossless internal thread measuring method.This is for spiral marking connection
Reliability and the security of production suffer from important meaning.
The content of the invention
It is an object of the invention to solve the deficiency in existing e measurement technology, there is provided a kind of unnecessary destruction helicitic texture
Lossless non-contacting detection method.
To achieve the above object, the present invention uses following technical schemes：
A kind of non-contacting interior threaded surface quality detection device of omnirange, including Charged Couple CCD, supplement light source, branch
Frame, blowing nozzle, air pump annex, tempered glass cover plate, guide rod, servomotor, sliding platform, ball-screw, motor driver, meter
Calculation machine, High_speed NIC, measured object；The Charged Couple CCD camera two, four groups of light source is supplemented, blowing nozzle is installed in support
On, tempered glass cover plate is covered above support；The guide rod, servomotor, mobile platform, ball-screw composition mechanical drive train
System；The rotation of one of Serve Motor Control detection means, another Serve Motor Control detection means move forward and backward.Entirely
Mechanical driving part may be mounted on platform and use；The air pump and annex are responsible for supplying to blowing nozzle；The High_speed NIC,
The picture that camera collects can be quickly transferred to computer and be used for post-processing by computer.
A kind of non-contacting interior threaded surface quality detection device of omnirange, comprises the following steps：
1) place the device on operating platform, the sliding platform in measured object, mechanical driving part can be negative
The servomotor of duty translation drives lower horizontal movement, coordinates ball-screw make it that detection part can be with the drive of electric rotating machine
Rotation；
2) open air pump and annex works by blowing nozzle, blow away measured object surface impurity, prevent impurity when the later stage from measuring
It is mistakenly considered flaw and damage；
3) when measuring componental movement to measured object inside, camera starts and shoots corresponding picture, and by shooting
Picture is delivered in computer, and the whole inner case of measured object can be photographed come camera by rotating and moving forward and backward；
4) picture is handled with computer, analyzes the size and situation of flaw or damage, judge that can measured object
Continue normal use.
The present invention compared with prior art, has following substantive distinguishing features and advantage：
Detection means of the present invention is simple to operate when application and detection, and internal thread is shot by big depth of field camera
Surface information, it is not necessary to the degree of impairment that helicitic texture can observes surface is damaged, because internal light source is dark, in camera
Surrounding is provided with supplement light source to ensure light source abundance, show that the surface of internal thread is believed by image processing techniques using computer
Breath, analysis measured object can continue normal use, have in terms of the security of screw measurement and spiral marking connection can play it is larger
Effect.
