Problems solved by technology

[0003] In use, the existing equipment will have a greater impact on the waveform captured by the sensor for the distance between the electromagnetic ultrasonic transducer and the workpiece to be tested made of magnetic material. In general, it is necessary to ensure that the electromagnetic ultrasonic transducer and the workpiece to be tested The surface of the workpiece is measured at a distance of 2 to 5mm, but manual hand-held electromagnetic ultrasonic transducers cannot guarantee this when det

Abstract

The invention relates to an automatic electromagnetic ultrasonic flaw detection apparatus, which comprises a probe cover, an electromagnetic ultrasonic transducer installed in the probe cover, and a detection control circuit system installed in the probe cover, wherein the tail portion of the electromagnetic ultrasonic transducer is connected to a rack, the rack can control the stretching of the electromagnetic ultrasonic transducer in the sensing channel of the probe cover after the rack is driven by the gear driven by a servo motor, a distance measurement head is arranged in the probe cover and can sense the distance between the probe cover and the surface of a work-piece to be detected, the distance signal detected by a sensor is received by the detection control circuit system, and the rotation of the servo motor is controlled, such that the automatic control of the distance between the electromagnetic ultrasonic transducer and the surface of the work-piece to be detected is achieved, and the detection fluctuation caused by the manual grip is solved.

Description

technical field [0001] The invention relates to the field of material testing and analysis, in particular to an electromagnetic ultrasonic automatic flaw detection device. Background technique [0002] The existing electromagnetic ultrasonic testing device is an important method for non-destructive testing of materials. It plays a very important role in product quality assurance and the safe operation of important equipment and components. For electromagnetic ultrasonic transducers and corresponding detection controls used in electromagnetic ultrasonic testing Circuit technology is relatively mature. It is based on the principle of magnetostrictive effect, since the magnetic field can cause the deformation of the microstructure of ferromagnetic materials. If an alternating magnetic field is applied to a ferromagnetic material. The alternating magnetic field makes it deform periodically, and the deformation of the microstructure makes it vibrate. Vibration can excite ultra...
