Magnetic particle flaw detector with adjustable detection space

Abstract

The invention discloses a magnetic particle flaw detector with adjustable detection space, comprising a base, magnetic coils, a fixed frame and a second fixed plate, wherein an electromagnetic deviceis arranged at each of two sides above the base, the electromagnetic device is clamped in a chute, meanwhile, the chute is formed in the upper surface of the base, a first threaded rod runs through the outer side of the electromagnetic device, the lower side of the first threaded rod is arranged in a threaded slot, meanwhile, the threaded slot is arranged on the bottom surface of the chute, the magnetic coils are arranged at the inner side of the electromagnetic device, an expansion link is arranged at the inner side of the magnetic coil, and the expansion link is fixed in the middle of the upper side of the base. The magnetic particle flaw detector with adjustable detection space is provided with the chute and the first threaded rod, and the electromagnetic device can slide to be convenient to adjust the distance between two magnetic coils, so as to be convenient for performing flaw detection on material flow of different lengths, and after the positions of the magnetic coils are adjusted, the first threaded rod penetrates through the electromagnetic device to be screwed into the threaded slot, so as to be convenient for fixing the electromagnetic device and the magnetic coils.

Description

technical field [0001] The invention relates to the technical field of magnetic particle flaw detectors, in particular to a magnetic particle flaw detector capable of adjusting detection distances. Background technique [0002] Magnetic particle flaw detection is to use the ferromagnetic material to be magnetized, due to the existence of discontinuity, the magnetic force lines on the surface and near the surface of the workpiece are locally distorted to generate a leakage magnetic field to absorb the magnetic powder applied to the surface of the workpiece, forming a visually visible magnetic field under suitable light. traces, thereby showing the location, shape and size of the discontinuity. [0003] Generally, the commonly used magnetic particle flaw detector is inconvenient to adjust the distance of flaw detection, and it is not convenient to adjust the height and width of the support frame according to the size of the material, which makes it inconvenient to perform flaw...
