Movable magnetic powder inspection device

Abstract

The invention discloses a movable magnetic powder inspection device which comprises an inspection box, an electric control box, castors and a display. The lower end of the inspection box is open, the electric control box is positioned behind the inspection box and higher than the same, the castors are mounted at the lower end of the inspection box, and the display is mounted on the upper portion of the electric control box. A support is arranged in the inspection box, a magnetizing component and a photographic scanning component are arranged on the support, the magnetizing component comprises a closed circuit iron core and a magnetizing coil winded on the closed circuit iron core, the photographic scanning component comprises an industrial camera and an illuminating lamp for assisting the industrial camera in shooting, a processor and a storage are arranged in the electric control box and connected with the industrial camera, the processor is connected with the storage, and a handle is arranged on the upper portion of the electric control box. Inspection efficiency is effectively improved, inspection precision is also improved, labor cost is reduced, and the movable magnetic powder inspection device has humanized design.

Description

technical field [0001] The invention relates to the technical field of flaw detection, in particular to a mobile magnetic particle flaw detection equipment for flaw detection of steel plates. Background technique [0002] In the machinery manufacturing industry, steel plates are widely used as a raw material, such as building buildings, bridges and tracks. The quality requirements of steel plates are very strict, so it is necessary to carry out effective flaw detection on steel plates, and magnetic powder can be used for the detection of steel plates. Flaw detection method. [0003] The principle of magnetic particle flaw detection utilizes the difference between the magnetic permeability of the surface defects of steel products and the magnetic permeability of steel. After magnetization, the magnetic field at the discontinuity of these materials will change, and a leakage magnetic field will be generated on the surface of the workpiece, thereby forming magnetic powder accum...

AI Technical Summary

Problems solved by technology

[0004] In the related technology, in the process of flaw detection of steel plate, due to the large area of ​​steel plate, the immobile magnetic particle flaw detection equipment is not suitable for flaw detection of large steel plate. Therefore, in the flaw detection process, manual small flaw detection equipment is usually used point by point The method of flaw detection, this flaw detection method requires a lot of labor, its flaw detection efficiency is low, and the labor intensity is high

[0005] In addition, the magnetic particle flaw detector uses a probe to detect flaws. The single flaw detection range is small and the efficiency is low. When the light is dark, the flaw detection effect is not good, and during the flaw detection process, the flaw detection information cannot be saved and transmitted in real time.
