Description
Technical field
The utility model relates to magnetic powder flaw detector, is specifically related to a kind of interchange yoke defectoscope.
Background technology
Magnetic powder inspection uses lossless detection method comparatively widely at present, particularly exchange yoke defectoscope, because employing ~ 220V power supply directly inputs, supporting without the need to other instruments, and have that structure is simple, volume is little, lightweight, be easy to carry, use the features such as flexible, easy to operate, detection speed is fast, obtain using more widely.But the interchange yoke defectoscope itself used at present does not possess illumination and ultraviolet irradiation function, when ambient brightness does not reach the brightness of flaw detection operation or work standard requirement, need other light source just can carry out flaw detection operation, when carrying out fluorescent magnetic particle flaw detection, also need special fluorescence irradiation apparatus, and need two people to coordinate just to carry out flaw detection operation.The problems referred to above impact exchanges the conformability of yoke defectoscope working environment, the flexible performance of use and work efficiency, adds use cost and operation labor intensity.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of working environment adaptability energy good, flexible and convenient to use, can improve testing efficiency and detection perform, and reduction use cost exchanges yoke defectoscope with operation labor intensity.
The technical scheme that the invention for solving the technical problem is taked is: a kind of interchange yoke defectoscope, comprises housing, iron core and feed cable; Described housing is the housing of inverted U-shape; Described iron core is the iron core of inverted U-shape, and this iron core is arranged in described housing, and the two iron cores outlets that two lower ends of this iron core are arranged by described housing lower end are respectively stretched out; At the middle part of described iron core, from inside to outside set gradually main coil, secondary coil and magnetizing coil; The bottom of described housing is provided with transparent window, in this transparent window, is provided with white light emitting diode and ultraviolet LED; Control circuit board is provided with in described housing; Described housing is provided with magnetization switch, lighting system selection key and brightness regulation and controls button.
Further, potting resin is provided with in described housing.
Further, the rear end of described housing arranges three core supply sockets, and described feed cable is connected with three described core supply sockets by core electric power plug.
Further, two lower ends of described iron core are hinged movable core respectively.
The beneficial effects of the utility model are:
1, interchange yoke defectoscope self is made to possess white-light illuminating and ultraviolet irradiation two kinds of light sources, when carrying out flaw detection operation, do not need other illumination and ultraviolet irradiation equipment and support personnel, thus reduce testing cost and labour intensity, improve the dirigibility and testing efficiency that exchange the use of yoke defectoscope simultaneously;
2, can lighting system selection and brightness regulation be carried out, thus under being adapted at various light condition, observe surface of the work magnetic trace state, be conducive to finding defect magnetic trace and making correct judgement, improve the accuracy detected;
3, structural design is more reasonable, simple, compact, and equal conditions lower volume is less, and weight is lighter, longer service life, and functional reliability, security are better.
Accompanying drawing explanation
Fig. 1 is this interchange yoke defectoscope structural representation.
Fig. 2 is that the A of Fig. 1 is to partial view.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, Figure 2, this interchange yoke defectoscope comprises housing 1, iron core 2 and feed cable 7; Described housing 1 adopts ABS material to be injection molded into two and fastens composition to after point shell, the housing of housing 1 entirety in inverted U-shape; The described iron core of iron core 2 in inverted U-shape, form by stamping forming silicon steel sheet is stacked, the major part of iron core 2 is arranged in described housing 1, and one section of two iron core arranged by described housing 1 lower end respectively of two lower ends export and stretch out; At the middle part of described iron core 2, adopt copper enameled wire to be from inside to outside wound around successively and form main coil 3, secondary coil 4 and magnetizing coil 5, install the iron core of the good coil of coiling in housing 1 after, filling potting resin 12 seals; In the bottom of described housing 1, rounded transparent window 8 is set, this transparent window 8 is arranged on described housing 1 posterior medial lower end, tilt in the middle of two magnetic poles of yoke, light source slants in the middle of two magnetic poles, can effectively prevent reflected light on the impact observing surface of the work magnetic trace; White light emitting diode 16 and ultraviolet LED 17 are set in transparent window 8, in Fig. 2 embodiment, at the high-power ultraviolet light emitting diode 17 of the center of transparent window 8 installation one with aluminium radiator fin, arrange ringwise in the surrounding of transparent window 8 and multiple white light emitting diode 16 is installed; In described housing 1, be provided with control circuit board 6, comprise rectification filtering voltage stabilizing circuit, LED drive circuit, single-chip microcomputer light adjusting circuit in this control circuit board 6, as accompanying drawing embodiment, control circuit board 6 is applicable to being arranged on housing 1 rear portion; Described housing 1 is provided with magnetization switch 9, lighting system selection key 11 and brightness regulation and controls button 10; Arrange three core supply sockets 13 in the rear end of described housing 1, described feed cable 7 is connected with three described core supply sockets 13 by core electric power plug 14; Be hinged movable core 15 respectively in two lower ends of described iron core 2, the movable core 15 of accompanying drawing embodiment is a joint, two joints that this movable core 15 also can be hinged.
