Description

Technical Field

[0001] The utility model belongs to the field of detection devices, and particularly relates to an ultrasonic probe fixture with an adjustable inner rotation. Background Art

[0002] Ultrasonic Testing (UT) is a non-destructive testing method that uses the propagation characteristics of ultrasonic waves to detect internal defects of materials, measure thickness, evaluate material properties, etc. Its main principle is to obtain information inside the material through the propagation, reflection, and attenuation of ultrasonic waves in the material. Ultrasonic testing mainly based on the following physical principles: Ultrasonic wave propagation: Ultrasonic waves are sound waves with a frequency higher than 20 kHz, and ultrasonic waves are emitted into the material to be detected through an ultrasonic probe. Reflection and diffraction: When ultrasonic waves encounter discontinuities (such as cracks, cavities, etc.) inside the material, reflection and diffraction will occur, generating echo waves. Receiving echo waves: The ultrasonic probe also acts as a receiver to receive the ultrasonic wave signals reflected from inside the material. Signal processing: By processing the received ultrasonic wave signals, it can be determined whether there are defects inside the material, as well as information such as the location and size of the defects.

[0003] An ultrasonic probe testing fixture is a device used to fix and position an ultrasonic probe. Its main purpose is to ensure that during ultrasonic testing, the probe can maintain stable contact and the correct angle, so as to obtain accurate and reliable test results.
