Description
Technical field
This utility model relates to ultrasound examination normal probe field, be specifically related to a kind of can the ultrasound examination normal probe of arbitrarily coupling。
Background technology
Ultrasonic Nondestructive, it is exactly utilize hyperacoustic characteristic, under the premise do not damaged or do not affect checked object serviceability, whether existing defects or inhomogeneities in detection checked object, provide the information such as the size of defect, position, character and quantity, and then judge the general name of all technological means of state of the art residing for checked object。Ultrasonic Nondestructive is the requisite effective tool of industrial development, has reacted a national Industry Development Level to a certain extent, and its importance gains public acceptance。In the fundamental research and instrument and equipment exploitation of Ultrasonic Nondestructive, between China and advanced country in the world, still have bigger gap。
During ultrasonic examination, ordinary straight probe is commonly used in the tubular structure surface of relatively plane surface and the large radius of curvature such as sheet material and detects a flaw。And when tubular surface is detected a flaw, probe and between detected material surface can due to the difference of surface configuration can not and the surface of ordinary ultrasonic probe closely attach, there is one section of air layer in probe and detected materials surface, this will hinder inside the incoming detected materials of ultrasound wave。The quality of coupling is closely related with the Quality of acoustical image graphic obtained。Coupling not exclusively can make ultrasonic energy losses, and resolving power reduces, image blurring, for obtaining high-quality signal wave, generally when detecting the not plane surfaces such as curved surface, it is necessary to the perspex layer of detecting head surface is carried out polishing according to curvature of curved surface and adjusts, so as to make probe realize attaching with curved surface and couple。This way is capable of normal probe flaw detection in curved surface situation, but improved probe also can only be detected a flaw under fixing radius of curvature, it is impossible to proceed the flaw detection of flat surface and other radius of curvature materials。Along with industrialized development, tubing model gets more and more, and radius of curvature difference is bigger, and the way that traditional normal probe polishing is repaired will produce greatly waste and production efficiency is low。
Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, provide the ultrasound examination normal probe of a kind of arbitrarily coupling, probe can be made to realize couple state under arbitrary plane or curved surface situation, substantially increase a kind of probe adaptability when various coupling flaw detections, need not frequently change probe, accurately quickly realize probe coupling, improve efficiency and the accuracy of ultrasound examination。
In order to reach the purpose of this utility model, technical scheme is as follows:
The ultrasound examination normal probe of a kind of arbitrarily coupling, has housing, it is characterised in that be provided with damping block in described housing, and the downside of damping block is provided with piezoelectric element, and the upper end of housing is provided with Signal connector, and Signal connector is connected with piezoelectric element by holding wire；The bottom of housing is provided with entrant sound colloid; the sidepiece of housing is provided with the colloid passage connected with entrant sound colloid, is filled with entrant sound colloid in colloid passage, and colloid channel roof is provided with curvature and regulates joint; the downside of entrant sound colloid is provided with protecting film, and the edge of protecting film is connected with housing。
This utility model has the advantages that
A normal probe can be met and can realize coupling when any contact surface, greatly improve the service efficiency of probe。This probe can be good at adapting to the ultrasound examination of high-volume, many specifications, difform material；Avoid the cumbersome process of polishing probe, and the locally coupled bad baneful influence that polishing error causes, make ultrasound examination occur becoming apparent from, waveform image more accurately and reliably, one probe repeatedly uses and has also greatly saved resource, more meets the energy-conservation and safety and environmental protection under existing situation。

Detailed description of the invention
Below in conjunction with embodiment, this utility model is further described, but protection domain of the present utility model is not limited solely to embodiment。
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the ultrasound examination normal probe of a kind of arbitrarily coupling, there is housing 3, housing 3 is internally provided with damping block 5, and damping block 5 is for absorbing the interference ultrasonic signal dispersed。The downside of damping block 5 is provided with piezoelectric element 6, and piezoelectric element 6 is used for exciting and received ultrasonic signal。The upper end of housing 3 is provided with Signal connector 1, and Signal connector 1 is for the transmission of waveshape signal, and Signal connector 1 is connected with piezoelectric element 6 by holding wire 4。The bottom of housing 3 is provided with entrant sound colloid 7, and entrant sound colloid 7 is positioned on the downside of piezoelectric element 6。The sidepiece of housing 3 is provided with the colloid passage 9 connected with entrant sound colloid, and colloid passage 9 top is provided with curvature and regulates joint 2, has been also filled with entrant sound colloid in colloid passage 9。The downside of entrant sound colloid 7 is provided with protecting film 8, and the edge of protecting film 8 is connected with housing 3, and entrant sound colloid 7 is held and shape protection by protecting film 8。
When inspection material surface is straight, probe working condition is identical with general normal probe；
When surface of detecting a flaw is convex surface, regulates joint 2 by curvature and extract unnecessary entrant sound colloid, until probe laminating detected materials surface completely, it is achieved couple completely。When the radius of curvature of convex surface changes, only need to continuing to regulate curvature and regulate joint 2, by changing radius of curvature value, thus changing the volume of entrant sound colloid, final realizing coupling of residue colloid and convex surface。
When surface of detecting a flaw is concave curved surface, regulates joint 2 by curvature and inject entrant sound colloid, until probe laminating detected materials surface completely, it is achieved couple completely。When the radius of curvature of concave curved surface changes, only need to continuing to regulate curvature adjustment joint 2, by changing radius of curvature value, continue to change the volume of entrant sound colloid, final realization residue colloid couples with convex surface。
Due to the change of radius of curvature, in order to realize coupling, the volume of entrant sound colloid inherently changes with radius of curvature according to calculating rule。Curvature adapter can increase according to the automatic Calculation of curvature radius of material parameter of input and needs or reduce the volume of entrant sound colloid, couples thus realizing automatically controlling probe。
Last it is noted that above example only in order to this utility model is described and and technical scheme described by unrestricted this utility model, therefore, although this utility model is had been carried out describing in detail by this specification with reference to each above-mentioned embodiment, but, it will be understood by those within the art that, still this utility model can be modified or equivalent replacement, and all are without departing from the technical scheme of spirit and scope of the present utility model and improvement thereof, it all should be encompassed in right of the present utility model。
