Technical Field

[0001] The utility model belongs to the technical field of flaw detector clamps, and in particular relates to a special-shaped part clamping table of a magnetic particle flaw detector. Background Art

[0002] Magnetic particle flaw detection is a process in which a ferromagnetic workpiece is magnetized. Due to the existence of discontinuity, the magnetic lines of force on the surface and near the surface of the workpiece are locally distorted, generating a leakage magnetic field, adsorbing the magnetic powder applied to the surface of the workpiece, and forming magnetic marks visible to the naked eye under appropriate lighting, thereby showing the location, size, shape and severity of the discontinuity. Most of the existing flaw detector fixtures can only clamp relatively regular workpieces for flaw detection. Most of the flaw detection work of special-shaped workpieces still uses manual spraying, which is labor-intensive, uneven spraying, and easily causes inaccurate flaw detection results. Therefore, a special-shaped part clamping table for a magnetic particle flaw detector is needed to solve the above problems. Utility Model Content
