Problems solved by technology

The single array element probe has only one array element, which cannot deflect and scan the ultrasonic beam. When the center frequency of the probe remains unchanged, the resolution and imaging capability of the probe are greatly limited.
Although the phased array probe can deflect the beam, it can only deflect the beam at a limited angle in the azimuth direction of the probe, and cannot deflect the beam in the elevation direction of the probe. 360° tomography and imaging of workpieces

Abstract

The application discloses an ultrasonic detection device and an ultrasonic transducer. The ultrasonic detection device comprises a ultrasonic transducer, a clamping assembly and a driving assembly, wherein the ultrasonic transducer is used for performing tomography on a workpiece to be detected and comprises a plurality of independent array elements, the plurality of array elements are surroundedinto a tubular object for one end of the workpiece to be detected to penetrate through, and the radiation surfaces of the plurality of array elements form the inner side wall of the tubular object; the clamping assembly is used for clamping the other end of the workpiece to be tested; and the driving assembly is connected with the clamping assembly and used for driving the clamping assembly to move. The ultrasonic detection device can be used for carrying out 360-degree tomography on a workpiece to be detected.

Description

technical field [0001] The present application relates to the technical field of ultrasonic nondestructive testing, in particular to an ultrasonic testing device and an ultrasonic transducer. Background technique [0002] In terms of ultrasonic nondestructive testing technology, most of the current commercial industrial testing ultrasonic transducers are single-array element probes, and a few are phased array probes. The single-element probe has only one array element, which cannot deflect and scan the ultrasonic beam. When the center frequency of the probe remains unchanged, the resolution and imaging capability of the probe are greatly limited. Although the phased array probe can deflect the beam, it can only deflect the beam at a limited angle in the azimuth direction of the probe, and cannot deflect the beam in the elevation direction of the probe. Workpieces undergo 360° tomography and imaging. Contents of the invention [0003] The technical problem mainly solved b...
