Abstract

The invention discloses a magnetic powder detection device for omnibearing detection of a steel structure. The device comprises a large fixed bottom plate. A left X-axis driving mechanism is fixed tothe left side of the upper end face of the large fixed bottom plate through screws. A left magnetic powder flaw detection mechanism is fixed above the left X-axis driving mechanism through screws. A right X-axis driving mechanism is fixed to the right side of the upper end face of the large fixed bottom plate through screws. A right magnetic powder flaw detection mechanism is fixed above the rightX-axis driving mechanism through screws. A Z-axis driving mechanism is connected to the middle of the lower end face of the large fixed bottom plate through screws. A Y-axis driving mechanism is fixed above the Z-axis driving mechanism through screws. A rotating platform is fixed above the Y-axis driving mechanism through screws. The device is simple in structure and convenient to use, omnibearing magnetization of workpieces of different sizes can be achieved through the left X-axis driving mechanism, the right X-axis driving mechanism, the Y-axis driving mechanism and the rotating platform,omnibearing cracks can be detected at a time, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of magnetic particle detection, in particular to a magnetic particle detection device for comprehensive detection of steel structures. Background technique [0002] Magnetic particle flaw detection uses the interaction between the leakage magnetic field at the defect of the workpiece and the magnetic powder. It uses the difference between the magnetic permeability of the surface of the steel product and the near-surface defects (such as cracks, slag inclusions, hairlines, etc.) and the magnetic permeability of the steel. After magnetization, these The magnetic field at the discontinuity of the material will be distorted, forming a part of the magnetic flux leakage, and the leakage magnetic field will be generated on the surface of the workpiece, thereby attracting the magnetic powder to form the magnetic powder accumulation at the defect - the magnetic trace, which shows the position and shape of the defect u...
