Abstract
A kind of magnetic powder inspection fluorescent light fittings, including lampshade and two ultraviolet lamp tubes, two ultraviolet lamp tubes are mounted below lampshade at 30-90 angle.Two ultraviolet lamp tubes are orthogonal.Lampshade is fixed with fluorescent tube, and lampshade is integrated with fluorescent tube, and one end of lampshade is fixedly mounted in the vertical support rod of one be additionally provided with.The utility model is used for the light units detected a flaw to angled weld seam, and the angled Fluirescence observation needed when intersecting seam inspection needs the intensity of illumination distribution with angle.Efficiently and accurately obtain the distribution of flaw detection magnetic liquid in time convenient for artificial or picture pick-up device.Improve the accuracy of flaw detection.For most widely used angled weld seam magnaflux, there is efficiently and accurately flaw detection effect.
Description
Technical field:
The utility model relates to a kind of facilities of magnetic powder inspection, and in particular to the magnaflux of a kind of pair of seam inspection
Component.
Background technique:
Large-sized steel cartridge type part needs to detect a flaw, and magnetic powder inspection utilizes the magnetic flux leakage and the phase interaction of magnetic powder at workpiece, defect
With the difference on steel product surface and near surface flaw (such as crackle, slag inclusion, hairline etc.) magnetic conductivity and steel magnetic conductivity is utilized in it
Different, distortion will occur for the magnetic field after magnetization at these material discontinuities, form workpiece surface at the flux leakage of part and produce leakage
Magnetic field, thus attract magnetic powder formed fault location magnetism powder accumulation --- magnetic trace, illumination appropriate (including use ultraviolet lamp or day
Light lamp) under the conditions of, defective locations and shape are shown, the accumulation of these magnetic powders is observed and explained, is achieved that magnetic powder
Flaw detection.The flaw detection of weld seam is must to pay the utmost attention to magnetic spy wound, in order to apply magnetic field and keep big magnetic field strength, intersects weld seam
Flaw detection requires the cooperation of fluorescent light, and single tube fluorescent lamp needs to deflect the angle of light when often light is mapped to weld seam.
It can be seen that the equipment of full Circumferential field, first technology includes that the applicant has had in terms of the offer of external magnetic field
A variety of, cardinal principle is: being wound on product and is magnetized with flexible cable, forming longitudinal magnetic field further includes even Circumferential field.For examining
Survey the discontinuity vertical with coil axis direction.
But it cannot be guaranteed the Luminance Distribution for weld seam of fluorescent lamp, therefore needed when angled intersection seam inspection
Fluorescent lamp needs improve to some extent, and especially need the fluorescent lamp light distribution with angle.
Utility model content:
The purpose of this utility model is to propose a kind of Novel magnetic powder flaw detection fluorescent light fittings in view of the above deficiencies, proposes one
The fluorescent lamp needed when planting angled intersection seam inspection needs the intensity of illumination distribution with angle.Convenient for artificial or picture pick-up device and
When efficiently and accurately obtain flaw detection magnetic liquid distribution.
Above-mentioned purpose is realized by following technical scheme: magnetic powder inspection fluorescent light fittings, including lampshade and two purples
Outer fluorescent tube is mounted below lampshade equipped with two ultraviolet lamp tubes at 30-90 angle.Magnetic flaw detection ink sprinkling equipment sprays magnetic flaw detection ink to tool
There is the surface of weld seam part, workpiece face of weld is carried out spray to carry out flaw detection being to have using magnetic powder inspection fluorescent lamp and observation device
The selection of benefit.
Magnetic powder inspection fluorescent lamp or/and magnetic flaw detection ink sprinkling equipment are slided on the slide rail, magnetic flaw detection ink sprinkling equipment sprays out
Mouth is directed at cartridge type part to be detected a flaw, and slowly and then observation can make full use of apparatus of the present invention after spray.
Circumferential field is used cooperatively: be the powered magnetic field of formation of radial and axial coil is formed together into magnetic field or compound
Magnetic field can detect a flaw to the multi-direction of cartridge type part when spraying magnetic flaw detection ink.Adapted Fluirescence observation effect of the invention is more preferable.
The utility model has the advantages that the utility model is used for the light units detected a flaw to angled weld seam, angled intersection
The Fluirescence observation needed when seam inspection needs the intensity of illumination distribution with angle.In time efficiently and accurately convenient for artificial or picture pick-up device
Obtain the distribution of flaw detection magnetic liquid.Improve the accuracy of flaw detection.For most widely used angled weld seam magnaflux, tool
There is efficiently and accurately flaw detection effect.Lampshade favorably protects the eyes of detection staff using dome structure.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment:
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate.It should be understood that following specific embodiments
The utility model is merely to illustrate without limiting the scope of the utility model.
The fluorescent light fittings as shown, Novel magnetic powder is detected a flaw, including lampshade 1 and ultraviolet lamp tube, the purple equipped with right angle distribution
Outer fluorescent tube is mounted below lampshade, wherein horizontal direction a fluorescent tube 2, and vertical direction one 3.Two ultraviolet lamp tubes hang down mutually
Directly.In particular by the ultraviolet lamp tube of 8-16W power.Lampshade 1 uses dome structure.
Lampshade is fixed with fluorescent tube, and lampshade is integrated with fluorescent tube, and one end of lampshade is fixedly mounted in vertical support rod,
And the angle of adjustable lampshade and fluorescent tube.In order to keep the observing effect of fluorescent lamp more preferable, 10-25 centimetres below fluorescent tube
Place's installation one flat plate shape Fresnel Lenses.One end of tabular Fresnel Lenses is mounted in vertical support rod.
