Magnetic material crack detection device

The utility model relates to a magnetic material crack detection device, which comprises a detection mechanism, a plurality of groups of detection prompt lamps, a power supply control box, fixed machine legs and a power distribution bridge, the fixed machine legs are symmetrically arranged on the bottom sides of the two ends of the power distribution bridge, the detection mechanism is fixed on the bottom side surface of the power distribution bridge, and the power supply control box is connected with the power distribution bridge. The multiple groups of detection prompting lamps are arranged on the top surface of the distribution bridge at equal intervals, and the power supply control box is connected to the side end of the distribution bridge. According to the magnetic material crack detection device, the arrangement of magnetic material crack detection is optimized, a traditional manual sampling inspection mode is changed and improved into a detection device with an electrical and optical detection mode, th
