Description

Technical Field

[0001] The utility model relates to the technical field of magnetic particle flaw detection, in particular to a magnetic particle flaw detection clamping device. Background Art

[0002] Magnetic particle inspection utilizes the interaction between the leakage magnetic field at the defects of the workpiece and the magnetic powder. It takes advantage of the difference in magnetic permeability between the surface and near-surface defects of steel products (such as cracks, slag inclusions, hairline, etc.) and the magnetic permeability of steel. After magnetization, the magnetic field at the discontinuity of these materials will be distorted, forming a leakage magnetic field on the surface of the workpiece where some magnetic flux leaks, thereby attracting magnetic powder to form magnetic powder accumulation at the defect - magnetic mark. Under appropriate lighting conditions, the position and shape of the defect are revealed. By observing and interpreting the accumulation of these magnetic powders, magnetic particle inspection is achieved.

[0003] However, the current device has a relatively simple structure, and the workpiece cannot be rotated after being clamped. If a more comprehensive magnetic particle inspection is performed on the clamped workpiece, it needs to be re-clamped, which makes the operation inconvenient. Moreover, if there are impurities on the surface of the clamped workpiece, it may affect the results of the magnetic particle inspection.

This magnetic particle inspection clamping device has a simple and reasonable structure, a novel design, simple operation, and convenient adjustment. It can effectively solve the defect of the existing clamping device that is difficult to adjust after clamping, and has high practical value.

[0005] Although the above patent achieves rapid adjustment and movement of the slide in the slide groove through the rotation of the screw, and then achieves rapid adjustment and movement of the movable frame, and achieves rapid clamping of the workpiece to be inspected, and at the same time, through the coordinated use of the second motor and the second hand wheel, the screw is driven in both automatic and manual rotation modes, which is convenient for meeting the user's usage needs; however, the device lacks cleaning components and auxiliary mechanisms, and cannot assist the clamping structure to clean impurities on the surface of the workpiece, so as to avoid affecting the results of magnetic particle inspection.
