Description
Technical field
The utility model relates to a kind of ultrasonic sensor, relates in particular to the wear-resisting probe of a kind of novel K3 ultrasound wave.
Background technology
Ultrasound wave refers to the mechanical wave of frequency higher than 20kHz, it is high that it has frequency, wavelength is short, diffraction phenomenon is little, particularly good directionality, can become ray and the features such as direction propagation, ultrasound wave is to liquid, the penetrating power of solid is very large, therefore ultrasound examination is widely used in industry, national defence, the aspects such as biomedicine, be particularly useful for industrial flaw detection effect fine, in ultrasound examination process, hyperacoustic transmitting and receiving realized by popping one's head in, the performance of ultrasonic probe directly affects hyperacoustic characteristic, affect hyperacoustic detectability, the probe using in ultrasound examination, to utilize the piezoelectric effect of material to realize electric energy, acoustic energy conversion, the critical component of probe is wafer, wafer is monocrystalline or a polycrystal thin slice with piezoelectric effect, its effect is that electric energy and acoustic energy are changed mutually, it is strong that such material has direct piezo electric effect, receiving sensitivity is high, mechanical property and electric performance stablity, the feature such as corrosion-resistant, but current piezoelectric chip is conventionally all very crisp, in the time that for test specimen, directly the mode of contact is carried out scanning along test specimen surface, wafer is easy to damage, for this reason, be everlasting below wafer and adhere to the thin diaphragm of one deck, the material of diaphragm is generally organic glass, in order to protect wafer and electrode layer, but in testing process the front end of ultrasonic probe diaphragm often and object to be detected rub, cause diaphragm wearing and tearing, even come off, shorten greatly the serviceable life of probe, cause great economic waste, affect to a certain extent normally carrying out of engineering detecting work.
Summary of the invention
The utility model provides a kind of novel K3 ultrasound wave wear-resisting probe, ensureing on the basis of ultrasonic probe normal index, performance, improve greatly the wear resistance of probe, extend to a great extent the serviceable life of ultrasonic probe, reduced significantly the testing cost of engineering flaw detection.
For achieving the above object, the utility model is realized by the following technical solutions:
The wear-resisting probe of a kind of novel K3 ultrasound wave, comprises organic glass protection film, copper sheet, probe body, and described organic glass diaphragm is fixed on the bottom of K3 angle probe main body, and copper sheet is fixed on the front end of organic glass diaphragm.
Compared with prior art, the beneficial effects of the utility model are:
The wear-resisting probe of a kind of novel K3 ultrasound wave; process structure is simple; by diaphragm and the key position of detection part friction being changed into the mode of wear-resistant material; in having ensured ultrasonic probe normal index, performance; improve greatly the wear resistance of probe; extend to a great extent the serviceable life of ultrasonic probe, reduced significantly the testing cost of engineering flaw detection.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is perspective view of the present utility model.
In figure: 1. organic glass diaphragm .2. copper sheet .3. probe body .4. joint.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
As shown in the figure; the wear-resisting probe of a kind of novel K3 ultrasound wave of the utility model; comprise organic glass protection film 1, copper sheet 2, probe body 3, described organic glass diaphragm 1 is fixed on the bottom of K3 angle probe main body 3, and copper sheet 2 is fixed on the front end of organic glass diaphragm 1.
Joint 4 is wires of connecting supersonic wave test instrument in order to connect.
Embodiment 1: the ultrasound probe header taking model as " 2.5P, 13X13K3 " is for example, specifically sets forth the new novel embodiment of this practicality, and test index after improving.
By original " 2.5P, 13X13K3 " front end of ultrasonic probe bottom organic glass diaphragm 1 removes a part, form a groove, the length of groove is identical with the width of diaphragm 1, the width of groove can not be wide, the width of groove is wide will cause damage to the inner acoustic absorbant of popping one's head in, the width of groove is advisable with 1.5mm after tested, the shape of copper sheet 2, the shape of size and groove, size is identical, copper sheet 2 is embedded in groove, bonding firmly by organic gel, leave standstill 24 hours, then through emery wheel corase grind, sand paper fine grinding, make organic glass diaphragm 1 and copper sheet 2 integrators, form a diaphragm that new abrasion resistance is high.
The utility model is the mode by diaphragm and the key position of detection part friction being changed into wear-resistant material, effectively raises the anti-wear performance of K3 ultrasonic probe.
The utility model is carried out to the test of indices:
The test of popping one's head in zero point, product export index is: (0-199.99) us, method of testing is: K3 ultrasound wave angle probe is placed in CSK-1A test block and is moved, measuring probe with steel ruler is 100mm with the measuring distance on arc top foremost, find the highest echo of R100, meet the index of dispatching from the factory of product through test test index of the present utility model.
The K value test of probe, is placed on ultrasound wave K3 angle probe in CSK-1A test block and moves, and finds the highest echo in Φ 50 holes, and Φ 50 is artificial defect, and test value is K2.8, meets K value testing standard.
Meanwhile, perpendicularity error≤3 ﹪ of ultrasonic investigation instrument, horizontal linearity error≤0.3 ﹪, resolving power >=32dB, dynamic range >=30dB, surplus sensitivity >=55dB (testing standard is the flat-bottom hole of 200mm, Φ 2).
Every method of testing, testing standard all meet international standard above, test result is through the multinomial gained of repeatedly testing of technician, the utility model is the change to probe fore-end material, the result of testing can prove by K3 angle probe front end inlay copper sheet on the indices of detection instrument all without affecting.
