Industrial flaw detection device based on audio amplitude and frequency

Abstract

The invention discloses an industrial flaw detection device based on audio amplitude and frequency, which comprises a pipeline to be subjected to flaw detection, wherein a flange plate is mounted at the end part of the pipeline to be subjected to flaw detection, a coaxial mounting ring is fixedly connected to the flange plate through a plurality of electric telescopic rods, and the mounting ring movably surrounds the outer side of the pipeline to be subjected to flaw detection; a supporting ring is fixedly connected to the inner side of the mounting ring, a slip ring is rotatably mounted on the supporting ring, a plurality of mounting bases are mounted at one end of the slip ring, annular teeth are arranged at the other end of the slip ring, the inner sides of the mounting bases extend towards the center of the mounting ring, and probe assemblies are fixedly connected to the ends of the inner sides of the mounting bases. According to the invention, the electric telescopic rods can drive the mounting ring to move on the outer side of the pipeline to be subjected to flaw detection, so that the probe assemblies are automatically moved to different positions of the pipeline to be subjected to flaw detection. The probe assemblies are symmetrically distributed at one end of the slip ring, and the rotation amplitude of the slip ring enables the probe assemblies to cover a complete circumference of the pipeline to be subjected to flaw detection.

Description

technical field [0001] The invention relates to the technical field of industrial flaw detection, in particular to an industrial flaw detection device based on audio amplitude and frequency. Background technique [0002] Industrial flaw detection is mainly used to detect cracks or defects inside metallic materials or components. Commonly used flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetrant flaw detection, eddy current flaw detection, gamma ray flaw detection and other methods. This non-destructive testing method is to use the sound, light, magnetic and electrical characteristics of the material to detect whether there are defects or inhomogeneities in the tested object without damaging or affecting the performance of the tested object. Information such as defect size, location, nature and quantity. [0003] At present, in the flaw detection of metal pipe fittings, the probe is usually manually mov...
