Description

Technical Field

[0001] The utility model relates to the technical field of clamping special-shaped parts of a magnetic particle flaw detector, in particular to a clamping platform for special-shaped parts of a magnetic particle flaw detector. Background Art

[0002] Magnetic particle detectors are suitable for wet magnetic particle inspection of surface and near-surface cracks and minor defects caused by casting, quenching, machining, fatigue, and other factors on various small and medium-sized parts, such as crankshafts, camshafts, and spline shafts. They are the preferred model for single-piece inspection, small-batch sampling, and large-scale inspection. Magnetic particle detectors, also known as portable flaw detectors, use thyristors as contactless switches, resulting in low noise, long life, simple operation, wide adaptability, and stable operation. Magnetic particle detectors are categorized by magnetization method as electromagnetic yoke flaw detectors and rotating magnetic field flaw detectors, and by current as AC, DC, and AC / DC dual-use models. The DC power supply is a rechargeable battery, making it suitable for field operation without a power source and for use on vessels, bridges, and pipelines where high voltage cannot enter. A single charge provides over six hours of continuous operation. The AC power supply is directly input from a ~220V power source, requiring no additional equipment. Its ease of operation, simplicity, light weight, and portability have made these instruments widely used. The Chinese utility model patent with patent number CN216504681U is a special-shaped part clamping table for a magnetic particle flaw detector. By manually rotating the first handle, the rotation of the rotating rod is driven. The thread on the outer side of the rotating rod cooperates with the thread of the threaded hole on the first bracket, so that the rotating rod moves to the left under the action of the bolt when it rotates, thereby realizing the abutment between the rotating rod and the support tube, and then driving the support tube to slide to the left on the limit tube. The movement of the support tube drives the first suction cup to abut the special-shaped workpiece, so that the first suction cup and the second suction cup clamp the special-shaped workpiece to the left and right, thereby realizing the fixation of the special-shaped workpiece on the clamping workpiece, making it easier for the flaw detection equipment to perform all-round flaw detection on the special-shaped parts.

[0003] The above devices still have certain problems in use. When fixing objects, the above devices need to use suction cups to abut against special-shaped workpieces. Multiple suction cups are adsorbed on the workpiece, covering a large area of ​​the workpiece. The area of ​​the workpiece covered by the suction cups cannot be detected. At this time, the area that can be detected by the magnetic particle detector is greatly reduced, affecting the detection effect of the magnetic particle detector. Utility Model Content
