Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic particle flaw detection, and particularly relates to a magnetic particle flaw detector for parts. Background Technique

[0002] Magnetic particle flaw detection is to utilize the fact that after ferromagnetic materials are magnetized, due to the existence of discontinuities, the magnetic lines of force on the surface and near-surface of the workpiece undergo local distortion to generate a leakage magnetic field (i.e., the magnetic field formed when the magnetic induction lines leave and enter the surface), which adsorbs the magnetic powder applied on the surface of the workpiece, forming magnetic traces visible to the naked eye under appropriate illumination, thereby showing the position, shape, and size of the discontinuities.

[0003] The Chinese patent with the comparative announcement number CN209167210U discloses a well-type magnetic particle flaw detector for parts, which includes a magnetic powder box, a spraying port, a support rod, and a base. A connecting piece is fixedly installed at the left end of the magnetic powder box, and the top of the connecting piece is connected to a top cover located above the magnetic powder box. Side plates welded to the upper surface of the magnetic powder box are provided on both the front and rear sides of the top cover. The magnetic powder box is internally provided with bases symmetrically on the left and right, and a first telescopic rod is arranged above the bases. The inner end of the first telescopic rod is fixedly connected to a housing, and the top end inside the housing is connected to a second telescopic rod. The bottom end of the second telescopic rod is connected to a cleaning plate through a card slot. The spraying port is installed at the middle position of the lower surface of the magnetic powder box. Sockets are provided on the surfaces of the front and rear sides of the right half of the magnetic powder box, and the right end of the magnetic powder box is connected to a connecting seat. The support rod is connected to the lower surface of the connecting seat, and a collar is sleeved on the outer surface of the support rod. The left end of the collar is connected to a turntable, and the left end surface of the turntable is connected to a third telescopic rod. The left end of the third telescopic rod is fixedly connected to a connecting plate, and fixing plates are symmetrically arranged up and down on the left end surface of the connecting plate. The inner end surfaces of the fixing plates are connected to springs.

[0004] However, the above patent only sprays parts from the top, and there are many places that are blocked and cannot be sprayed, making it difficult to ensure the comprehensiveness and uniformity of the magnetic powder liquid spraying. Therefore, a new device needs to be designed. Content of the Utility Model
