Special pass-type magnetic particle flaw detector for axle with gear

Abstract

The invention relates to the technical field of magnetic particle inspection, in particular to a special pass-type magnetic particle flaw detector for an axle with a gear. The special pass-type magnetic particle flaw detector comprises a rack, a workpiece transfer mechanism, a circumferential magnetization mechanism, a workpiece rolling mechanism, a longitudinal magnetization mechanism, an independent gear magnetization mechanism, a magnetic suspension spraying mechanism, a fluorescent lamp and an electrical control system, wherein the independent gear magnetization mechanism comprises a cross coil, a mounting plate, a lifting cylinder and a first guide rod; and when the cross coil descends, the gear can be partially surrounded. The special pass-type magnetic particle flaw detector for the axle with the gear can simultaneously complete magnetic flaw detection of the axle and the gear in one flaw detection process, and is convenient and efficient.

Description

technical field [0001] The invention relates to the technical field of magnetic particle flaw detection, in particular to a special through-type magnetic particle flaw detection machine for axles with gears. 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 def...
