Description
Technical field
The present utility model relates to a kind of X ray filter plate of adjustable filtering grade, particularly a kind of for industrial nondestructive testing X ray filter plate.
Background technology
It is most important method in industrial nondestructive testing that X ray detects, its principle is to utilize the short character that is easy to penetrate object of X ray wavelength, because being absorbed with scattering, ray there is certain attenuation properties simultaneously, according to the difference of transmitted intensity after decaying by the each position of workpiece, detect inside workpiece uncontinuity, the plane projection that material category variation or geometry variation etc. form, thereby reach the object of understanding interior of articles situation, can effectively detect the internal physical defect of tested workpiece, as the shortcoming of material inside, structure situation and the inherent vice etc. of airtight other material of interior of articles.
X-ray production apparatus is by the vacuum tube two ends making alive that has negative and positive the two poles of the earth at, negative electrode is heated to incandescent state release electron impact anode metal target and comes X ray excited, the X ray exciting by electron impact has the wavelength of different length, the shorter X ray penetration capacity of its medium wavelength is poor, scattering easily occurs, and is the principal element of the safety of harm to field personnel; And after the shorter soft ray of wavelength is scattered, beat from different directions on digital imagery plate, have a strong impact on sharpness and the contrast of digital picture, be unfavorable for technician's defects detection and judgement; In order to reach more desirable digital picture quality, must select the filter plate of different-thickness to filter the soft ray being excited according to electric pressure, to prevent from excessively filtering and filtering the not enough impact bringing.
Therefore, the utility model, for the problem of above-mentioned existence, provides a kind of X ray filter plate of capable of regulating filtration grade, can electric pressure as required adjust X ray filter plate filtration grade, to obtain best digital picture quality.
Summary of the invention
The purpose of this utility model is: according to excitation of X-rays principle and ray characteristics, design a kind of X ray filter plate of capable of regulating filtration grade, can electric pressure as required adjust X ray filter plate filtration grade, to obtain best digital picture quality, improve efficiency and the accuracy of equipment X ray defects detection.
An X ray filter plate for adjustable filtering grade, the utility model is by filter plate, through the breakdown screw in filter plate screwing hole, forms with the nut of screw fit with the overlapping filtration grade adjustable plate of filter plate, is provided with the clamping slot of open type in the both sides of filtering board; Offer locating slot in filtration grade adjustable plate both sides, locating slot and breakdown screw fit are fixed filtration grade adjustable plate; On filtration grade adjustable plate Yu by the overlapping same position of the clamping slot on filter plate, also offer clamping slot.The utility model filter plate is adopted and is formed from aluminium, thickness 1～2mm; Filtration grade adjustable plate adopts aluminium or copper to become, and thickness is 0.5mm or 1mm.The utility model locating slot is arc.Two locating slots that the utility model is offered are arc, when installation, can first buckle into one end breakdown screw along the rotation of locating slot track, then around the breakdown screw rotation clamping other end.The utility model, all by the clamping slot being provided with, coordinates clamping with resilient balls inside X-ray production apparatus window.
Of the present utility model according to excitation of X-rays principle and ray characteristics, in conjunction with X ray digital imagery principle and picture quality influence factor, design a kind of portable X ray filter plate of adjustable filtering grade, improve the sharpness of digital picture.
Useful result of the present utility model: according to equipment X ray Non-Destructive Testing principle and digital picture quality analysis of Influential Factors, designed a kind of can be when detecting demand voltage adjust the X ray filter plate of ray filtration grade, effectively filter penetration capacity poor and easily launch the soft ray of scattering, avoid the impact of soft ray on digital picture quality, improved technician's detection efficiency and accuracy.

Embodiment
Further set forth the utility model content below in conjunction with drawings and Examples.
See Fig. 1, Fig. 2, Fig. 3, an X ray filter plate for adjustable filtering grade, the utility model is by filter plate 1, through the breakdown screw 2 in filter plate screwing hole, form with the nut 3 of screw fit with the overlapping filtration grade adjustable plate 5 of filter plate, be provided with the clamping slot 4 of open type in the both sides of filtering board 1; Offer locating slot 6 in filtration grade adjustable plate 5 both sides, locating slot 6 coordinates with breakdown screw 2 fixing filtration grade adjustable plate 5; On filtration grade adjustable plate 5 Yu by the overlapping same position of the clamping slot 4 on filter plate 1, also offer clamping slot 4.The utility model filter plate 1 is adopted and is formed from aluminium, thickness 1～2mm; Filtration grade adjustable plate 5 adopts aluminium or copper to become, and thickness is 0.5mm or 1mm.The utility model locating slot 6 is arc.Two locating slots 6 that the utility model is offered are arc, when installation, can first buckle into one end breakdown screw 2 along locating slot 6 track rotations, then around the breakdown screw 2 rotation clamping other ends.The utility model, all by the clamping slot 4 being provided with, coordinates clamping with resilient balls inside X-ray production apparatus window.
The method of operating of this device is as follows:
1, X ray detection technique personnel select suitable tube current and tube voltage according to material and the thickness of detected workpiece or equipment;
2, according to selected tube voltage and tube current intensity, determine X ray filtration grade, select the filtration grade adjustable plate 5 of suitable material and thickness;
3, filtration grade adjustable plate 5 is buckled into one end breakdown screw 2 along locating slot 6 track rotations, then around the breakdown screw 2 rotation clamping other ends;
4, whole device is fixed on to X-ray production apparatus window by clamping slot 4, can starts X ray and detect;
If 5 need to adjust exposure tube voltage and tube current, can repeat above-mentioned steps 2～4.
