Description
Technical field
The utility model relates to workpiece inspection field, particularly relates to the many group switching centres of magnetic powder inspection and wears excellent method magnetization erecting device.
Background technology
Magnetic powder inspection: after ferrimagnet and workpiece are magnetized, due to the existence of uncontinuity, the magnetic line of force on surface of the work and nearly surface is made to occur locally abnormal and produce stray field, absorption is applied to the magnetic of surface of the work, be formed in appropriate light according to lower visual visible magnetic trace, thus show discontinuous position, shape and size.
The hollow magnetic material work piece magnetic powder inspection method larger to diameter dimension has two kinds at present
1, adopt the flaw detection of single, central conductor (wearing rod) method, magnetization current needs to increase along with the increase of workpiece, and the network load made is comparatively large, easily produces tripping operation power-off fault, and consumes very large power.
2, eccentric segmented conductor (wearing rod) method is adopted to detect a flaw, same workpiece repeats magnetization often, working strength is large, and the flaw detection of consumed power single, central conductor (wearing rod) method is the same, and the Circumferential field set up is uneven, area coverage is little, magnetization sensitivity is low, easily produces to leak to visit, and the Stability and dependability waiting magnetic powder inspection is declined.
In magnetic powder inspection, resultant magnetization is an important detection means in Non-Destructive Testing, the parts that the magnetic materials such as iron and steel make are passed to big current and makes it magnetization, if body surface or near surface defectiveness (crackle, folding, snotter etc.) exist, because their right and wrong are ferromagnetic, the resistance passed through the magnetic line of force is very large, and the magnetic line of force can produce leakage field near these defects.When being applied on object by magnetic (being generally magnetic iron oxide powder) good for magnetic conductivity, the stray field near defect will hold magnetic, heaps and forms visible magnetic mark trace, thus Flaw display out.Traditional resultant field is the synthesis of circumference and longitudinal magnetization.The mode of longitudinal magnetization is that the parts that need detect a flaw are placed in solenoid shape coil, at coil by producing the longitudinal magnetic field axially parallel with solenoid shape coil during electric current.The mode of circumferential magnetization part is directly applied electric current or in hole in piece part, penetrate conduction axle on conduction axle, apply the electric current generation Circumferential field vertical with direction of current.When mechanical component that are hollow in square shaped or circular hollow magnetic material carry out magnetic powder inspection, for detecting the crackle of surface of the work and circumference vertical direction, part must be made to carry out circumferential magnetization, set up circumferential magnetic field.Conventional method adopts single, central conductor (wearing rod) method, and magnetization current needs to increase along with the increase of workpiece, and the network load made is comparatively large, easily produces tripping operation power-off fault, and consume very large power.The eccentric segmentation that can only adopt in the conventional way detects.Because conductor (wearing rod) is eccentric, same workpiece repeats magnetization often, working strength is large, the flaw detection of consumed power single, central conductor (wearing rod) method is the same, and the Circumferential field set up is uneven, area coverage is little, and magnetization sensitivity is low, easy generation is leaked and is visited, and the Stability and dependability waiting magnetic powder inspection is declined.
