Abstract
The embodiment of the utility model discloses temperature measurement ultrasonic transducer for the ultrasonic transducer who detects a flaw, be provided with the detecting element of making with piezoceramics or quartzy wafer in the ultrasonic transducer, ultrasonic transducer one end is provided with the connector lug, and the other end is provided with and is used for surveing the thermo detector of being surveyed detection workpiece temperature, the embodiment of the utility model provides a temperature measurement ultrasonic transducer, the device comprises ordinary ultrasonic transducer, thermo detector display device, and this embodiment is additional survey workpiece temperature a device on ultrasonic transducer, can show directly perceivedly and examined the workpiece surface temperature, not only can save measure the temperature's before at every turn detecting step, can also guarantee the temperature condition and at the within range that the standard required, ensure detection quality.
Description
Technical field
The utility model relates to probe field, particularly relates to a kind of thermometric ultrasonic probe.
Background technology
Ultrasound wave is frequency higher than the mechanical wave of 20 kilo hertzs.Frequency conventional in ultrasonic inspection is 0.5 ~ 10 megahertz.This mechanical wave can be propagated with certain speed and direction in the material, runs into the different heterogeneous interface of acoustic impedance (bottom surface etc. as defect or measured object) and will produce reflection, reflect and waveform transformation.This phenomenon can be used to carry out UT (Ultrasonic Testing), the most frequently used is pulse reflection method, during flaw detection, the voltage that pulse oscillator sends is added in probe upper (detecting element made with piezoelectric ceramics or quartz wafer), the ultrasonic pulse sent of popping one's head in enters material by acoustic coupling medium (as machine oil or water etc.) and propagates wherein, and after running into defect, part reflected energy returns probe along former approach, probe is changed into electric pulse again, is presented on the video screen of oscillatron through instrument amplification.According to the position of flaw echo on video screen and amplitude (making comparisons with the reflection wave amplitude of artificial defect in reference block), position and the approximate size of defect can be measured.In said method, ultrasonic velocity is a very important parameter, and under we adopt normal temperature usually, velocity of ultrasonic sound is as the standard velocity of sound.But the transmission speed of ultrasound wave on high-temperature medium has very large deviation, for ensureing reliability and the accuracy of ultrasonic testing results, we will first determine member temperature to be checked within the specific limits when detecting, usually we use land surface pyrometer to measure, and it is much loaded down with trivial details that this makes Ultrasonic Detection add.
Summary of the invention
The utility model embodiment technical matters to be solved is, there is provided one can show examined workpiece surface temperature intuitively, not only can save each step detecting pre-test temperature, can also ensure that temperature conditions is in the scope of standard-required, guarantee the thermometric ultrasonic probe of Detection job.
Described thermometric ultrasonic probe, for the ultrasonic probe of detecting a flaw, be provided with the detecting element made with piezoelectric ceramics or quartz wafer in described ultrasonic probe, described ultrasonic probe one end is provided with connector lug, and the other end is provided with the thermo detector for measuring tested detection workpiece temperature.
Implement the utility model embodiment, there is following beneficial effect:
The utility model embodiment thermometric ultrasonic probe, device is popped one's head in by normal ultrasound waves, thermo detector display device is formed, the device of the present embodiment additional mensuration workpiece temperature on ultrasonic probe, examined workpiece surface temperature can be shown intuitively, not only can save each step detecting pre-test temperature, can also ensure that temperature conditions is in the scope of standard-required, guarantees Detection job.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
Thermometric ultrasonic probe described in the utility model embodiment, for the ultrasonic probe 1 of detecting a flaw, the detecting element 2 made with piezoelectric ceramics or quartz wafer is provided with in described ultrasonic probe 1, described ultrasonic probe 1 one end is provided with connector lug 3, and the other end is provided with the thermo detector 4 for measuring tested detection workpiece temperature.
The utility model embodiment thermometric ultrasonic probe, device is popped one's head in by normal ultrasound waves, thermo detector display device is formed, the device of the present embodiment additional mensuration workpiece temperature on ultrasonic probe, examined workpiece surface temperature can be shown intuitively, not only can save each step detecting pre-test temperature, can also ensure that temperature conditions is in the scope of standard-required, guarantees Detection job.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
