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 that a kind of Novel magnetic powder flaw detection intersects fluorescent tube fluorescent lamp dress in view of the above deficiencies
It sets, proposes that the fluorescent lamp needed when a kind of angled intersection seam inspection needs the intensity of illumination distribution with angle.Convenient for artificial or
Picture pick-up device efficiently and accurately obtains the distribution of flaw detection magnetic liquid in time.
Above-mentioned purpose is realized by following technical scheme: magnetic powder inspection intersects fluorescent tube fluorescent light fittings, including lampshade
And ultraviolet lamp tube, the ultraviolet lamp tube equipped with cross-distribution are mounted below lampshade, wherein the two of horizontal direction piece are in one line,
A vertical word direction has four fluorescent tubes.A vertical word direction has two fluorescent tubes above a word, and two fluorescent tubes are under a word
Side is uniformly distributed.
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, the 10-25 centimeters below fluorescent tube install one flat plate shape phenanthrene alunite
That lens.
Magnetic flaw detection ink sprinkling equipment sprays magnetic flaw detection ink to the surface with weld seam part, intersects fluorescent tube fluorescent lamp using magnetic powder inspection
And observation device spray to workpiece face of weld detect a flaw and is advantageous selection.
Magnetic powder inspection is intersected into fluorescent tube fluorescent lamp or/and magnetic flaw detection ink sprinkling equipment slides on the slide rail, magnetic flaw detection ink spray is set
Standby discharge outlet is directed at cartridge type part to be detected a flaw, and slowly and then observation can make full use of the dress of the utility model after spray
It sets.
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.
As shown, magnetic powder inspection intersects fluorescent tube fluorescent light fittings, including lampshade 1 and ultraviolet lamp tube, it is equipped with cross-distribution
Ultraviolet lamp tube be mounted below lampshade, wherein for the two of horizontal direction piece fluorescent tube 2 in one line, a vertical word direction has four
Root.A vertical word direction has two fluorescent tubes 3, two fluorescent tubes 3 above a word to be uniformly distributed below a word.Lampshade and fluorescent tube
Fixed, and lampshade is integrated with fluorescent tube, one end of lampshade is fixedly mounted in vertical support rod, and adjustable lampshade and
The angle of fluorescent tube.In order to keep the observing effect of fluorescent lamp more preferable, the 10-25 centimeters installation one flat plate shape below fluorescent tube is luxuriant and rich with fragrance
Nie Er lens 4.One end of tabular Fresnel Lenses 4 is mounted in vertical support rod.Using the ultraviolet lamp tube of 8-16W power.
Lampshade 1 uses dome structure, fluorescent tube installation insertion dome.
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 4.One end of tabular Fresnel Lenses is mounted in vertical support rod.Tabular is luxuriant and rich with fragrance
Nie Er lens first with the magnifying glass for amplifying 1.5 times, are suppressed, focal length is at 50 centimetres or more by PMMA.
