Problems solved by technology

Although the existing electromagnetic ultrasonic transducer has a good transducing effect, when the electromagnetic ultrasonic transducer scans the edge of the metal component, the shape of the edge of the metal component will have a certain impact on the echo, thereby affecting the detection accuracy
Because most metal components have corners, when the existing electromagnetic ultrasonic transducer detects metal components, due to the shape characteristics, there are many dead corners that cannot be detected when scanning the frame or corner of the metal component, which affects the feedback. Effective judgment of wave signal or defect echo signal

Abstract

The invention relates to the technical field of metal component nondestructive testing, in particular to a Reuleaux triangle electromagnetic ultrasonic transducer, which comprises a transducer main body and a rotary scanning unit, wherein the rotary scanning unit comprises a rotor engine and a central gear, the central gear is connected with the transducer main body, the rotor engine drives the central gear to rotate, the central gear drives the transducer main body to rotate, and the outer edge of the transducer main body is in the shape of a Reuleaux triangle. According to the invention, the rotary scanning unit comprises a rotor engine and a central gear, the rotor engine drives the central gear to rotate so as to drive a transducer main body to rotate, the transducer main body is used for generating vertically downward transverse waves in a metal component so as to scan the metal component, and the outer edge of the transducer main body is in the shape of a Reuleaux triangle, Even if the transducer main body scans the frame area of the metal component, the transducer main body can be in contact with the corners of the metal component, so that the effect of no dead angle in scanning is achieved.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing of metal components, in particular to a Leroux triangle electromagnetic ultrasonic transducer. Background technique [0002] Electromagnetic ultrasonic transducers have the advantages of non-contact detection, no coupling agent, and no pretreatment of the surface of metal components, and are widely used in metal detection, online scanning detection, etc. Electromagnetic ultrasonic transducers can be used not only for metal crack detection, but also for detecting the thickness of metal plates. Because the electromagnetic ultrasonic transducer will not affect the detection accuracy due to the couplant during the detection process, the electromagnetic ultrasonic transducer has great advantages in metal crack detection and thickness measurement. [0003] At present, most electromagnetic ultrasonic transducer structures are mostly composed of cylindrical permanent magnets and helical c...
