A cavity is arranged inside the shell body; a probe is cooperatively arranged in the cavity; a stress measuring device is installed at the bottom of the cavity and contacts with the bottom of the probe; and a display device is mounted at an external side of the shell body and is in electrical connection with the stress measuring device. With such a structure, the stress detection apparatus for the novel ultrasonic probe provided by the invention can visually show stress conditions of the probe in utilization.
Description
Technical field
The present invention relates to the UT (Ultrasonic Testing) field, particularly relate to a kind of dynamics pick-up unit of ultrasonic probe.
Background technology
When ultrasound wave is propagated in material to be detected; The acoustic characteristic of material and the variation of interior tissue produce certain influence to hyperacoustic propagation; Technology through the detection of ultrasound wave degree of susceptibility and situation being understood material property and structural change is called ultrasound detection; UT (Ultrasonic Testing) is to utilize ultrasonic energy to penetrate stretching into of metal material, and when getting into another cross section by a cross section, and the characteristics that reflection take place in section edges are checked a kind of method of defective part.
Present ultrasonic detecting technology still receives many restrictions because of the complicacy of the especially on-the-spot testing conditions of rope and the limitation of ultrasonic detection equipment etc.In testing process, the coupling situation has direct relation with the pressure that acts on the probe.In the UT (Ultrasonic Testing) process; The power that acts on the probe directly has influence on the mechanical couplings degree surperficial with measured object; Can produce bigger influence for measurement result, especially perpendicular to the power of detection plane direction, particularly the acting force in the probe moving process is difficult to control.Therefore need to propose a kind of pick-up unit that can detect the stressed degree of probe flaw detection.
