Abstract
The utility model provides a calibrating device for centering a focus point of an X-ray tube. The calibrating device comprises a dead-end tube and a transparent cross reticule in the dead-end tube; external threads connected with the threads for mounting the ray window of a light chopper are formed at the open end of the dead-end tube; a visual hole is formed in the center of the closed end of the dead-end tube; the axes of the visual hole is perpendicular to the transparent cross reticule and intersects the cross intersection point of the cross reticule; and the distance between the closed end of the dead-end tube and the transparent cross reticule is at least 4 to 5 times of that between the transparent cross reticule and the open end of the dead-end tube. As the open end of the dead-end tube of the calibrating device is mounted on the ray window of the light chopper, the center of the ray window coincides with the intersection point of the cross reticule of the calibrating device according to the principle of sight alignment. The position can be adjusted to cause the visual hole, the cross curve centre, and the focus point of the X-ray tube to be marked on the same line, and the marked position of the focus point is right in the center of the ray window. The utility model has the outstanding advantages of accurate and fast positioning, and great improvement of work efficiency, thereby being an efficient tool for marking, centering and detecting the focus point of the X-ray tube.
Description
Technical field
The utility model belongs to calibrating installation, particularly relates to a kind of X-ray tube focus centering calibrator.
Background technology
X-ray tube is provided with pipe box usually, so that the installing and using of X-ray tube.The installation of X-ray tube is strict with its focus and must be coincided with the ray window geometric center that photochopper is installed.The external screw thread that photochopper setting is connected with the ray window.
Producing and keeping in repair in the practice, the X-ray tube focus only is to rely on veteran technician to be adjusted with the method for range estimation with overlapping of the ray window geometric center that photochopper is installed, and does not find the practical and effective instrument as yet.
Above-mentioned method of adjustment by rule of thumb exists inefficiency, the higher practical problem of rework rate.
Summary of the invention
The utility model is only to adjust method that X-ray tube focus and the ray window geometric center that photochopper is installed coincide by rule of thumb and have that efficient is low, the rework rate technical problems of high in order to solve, and proposes a kind of X-ray tube focus centering calibrator.
The utility model is taked following technical scheme for achieving the above object: this calibrator is made of the transparent cross hair plate in blind pipe and the blind pipe, the blind pipe opening end is provided with the external screw thread that is threaded with the ray window that photochopper is installed, the blind end center of blind pipe is provided with the eyesight that diameter is 0.8-1.2mm, the eyesight axis is vertical with transparent cross hair plate and crossing with its cross intersection point, and the spacing of blind pipe blind end and transparent cross hair plate is transparent cross hair plate and blind pipe opening end spacing 4-5 times at least.
The utility model can also be taked following technical measures:
Described blind elbow length is 250-350mm.
The blind end of described blind pipe is the end cap that is threadedly connected to blind pipe body one end, and the end cap center is provided with eyesight.
The beneficial effects of the utility model and advantage are: this centering calibrator is made according to the principle of sight alignment, the blind pipe opening end is installed on photochopper ray window, and the center of circle of ray window overlaps naturally with the venter of relicle of the transparent cross hair plate of this centering calibrator.Adjust X-ray tube about, position, the left and right sides, make eyesight, cross hairs center and the X-ray tube focus mark line that coexists, this moment, the position of focus mark was in the center of ray window.The utlity model has accurate positioning, fast, the outstanding advantage of greatly increasing work efficiency, also be the efficient tool that X-ray tube focus mark centering is detected.
Description of drawings
Accompanying drawing 2 is transparent cross hair plate structure schematic diagrames.
Accompanying drawing 3 is embodiment 2 structural profile schematic diagrames.
Number in the figure: 1 blind pipe leading portion, 2 blind pipe back segments, 2-1 external screw thread, 3 blind ends, 4 eyesights, 5 transparent cross hair plates, 6 end caps.
Embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing thereof.
