Description

Technical Field

[0001] The invention relates to the technical field of open micro-focus ray tubes, and in particular to a beam extension device applied to open micro-focus ray tubes. Background Art

[0002] Due to the advantages of open-tube micro-focus X-ray tubes in imaging geometric clarity, magnification, scattered ray attenuation and detail recognition sensitivity, they can make up for the shortcomings of conventional X-ray imaging equipment and have a wide range of applications in digital real-time imaging (DR) detection and industrial CT detection, including electronic chips, circuit boards, aircraft engines, weapon parts, complex assemblies, castings and forgings, etc. The application areas cover the detection of small defects in composite materials, plastics, light metals, fiber-reinforced materials, etc. in aviation, aerospace electronics industry.

[0003] The current open micro-focus X-ray tube heads all generate x-rays directly from the target surface. Due to the structure of the tube head itself, x-rays are mostly emitted directly from the target surface at the end of the tube head in a 160° fan shape. If the interior of a component is to be inspected, the internal space of the component needs to be larger than the overall size of the micro-focus X-ray tube head; limited by the external dimensions of the open-tube micro-focus X-ray tube, the tube head cannot be inserted into slender cylindrical components, resulting in difficulty in the inspection of slender cylindrical components, low inspection efficiency, and high inspection costs. In addition, the current open micro-focus X-ray tubes and their functional products are expensive, and the capital and time costs during the maintenance process are very high.

[0004] Therefore, an open-tube micro-focus X-ray tube is required to have a function of being able to probe into a capillary tube for detection without affecting the detection quality and reducing the cost. Summary of the invention

[0005] The present invention mainly solves the technical problems of the current open-tube micro-focus X-ray tube in detecting slender tube-like parts, such as difficulty in detection, low detection efficiency and high detection cost, and proposes a beam extension device applied to the open-tube micro-focus X-ray tube, which can be extended into slender tube-like and tube-like parts, increases the detection length of the open-tube micro-focus X-ray tube head, and realizes the detection of slender tubes and tubes.

[0006] The present invention provides a beam extension device for an open micro-focus ray tube, comprising: a target head, a jacket, a central pipeline, an adjustment block, a sleeve, a base, and a connecting flange;

[0022] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for the convenience of description, only the parts related to the present invention are shown in the accompanying drawings, rather than all the contents.

[0023] like Figure 1-2 As shown, an embodiment of the present invention provides a beam extension device for an open micro-focus ray tube, comprising: a target head 01, a jacket 02, a central pipeline 03, an adjustment block 04, a jacket 05, a base 06, and a connecting flange 10.

[0024] The input end of the central pipeline 03 is inserted into the base 06, and the output end of the central pipeline 03 is provided with the target head 01; the outer cover 02 is provided on the outside of the central pipeline 03. Correspondingly, the input end of the cover 02 is also inserted into the base 06. The central pipeline 03 and the cover 02 are pluggable and installed in the base 06, and different lengths of the cover 02 and the central pipeline 03 can be selected, so that different beam exit positions can be extended.

[0025] A coolant gap is left between the outer jacket 02 and the central pipeline 03. Two water pipe joints 07 are provided on the base 06; the water pipe joints 07 are connected to the coolant gap. Coolant is poured into the coolant gap through the water pipe joints 07; the electron beam channel therein is water-cooled through the coolant gap between the outer jacket 02 and the central pipeline 03 so that it can work normally.

[0026] The input end of the central pipeline 03 is connected to the positioning window 09 through the sleeve 05; the sleeve 05 is placed inside the base 06; and the positioning window 09 is fixed at the center of the base 06.

[0027] The end of the base 06 is fixedly provided with a connecting flange 10; the positioning window 09 is located at the center of the connecting flange 10. The positioning window 09 is used to locate the tube head of the open micro-focus X-ray tube, and the connecting flange 10 is used to connect with the tube head of the open micro-focus X-ray tube. Specifically, the connecting flange 10 wraps around the end of the base 06, and the other end is connected to the tube head of the open micro-focus X-ray tube.

[0028] A plurality of adjustment blocks 04 are arranged around the base 06; the plurality of adjustment blocks 04 are against the outer sleeve 02. Specifically, a plurality of adjustment holes are arranged around the base 06, and the adjustment blocks 04 are placed in the corresponding adjustment holes. By extending into the adjustment holes, the adjustment blocks 04 are adjusted to adjust the outer sleeve 02 and the central pipeline 03 so that the electron beam inside can hit the center of the target head 01.

[0029] The base 06 is provided with a cable window 08, which is electrically connected to a cable line, which is placed in the base 06 and wound around the outside of the sleeve 05 to form a coil, and the cable line does not contact the sleeve 05. The direction of the electron beam can be adjusted by adjusting the working parameters of the cable line.

[0030] The target head 01 is a directional beam emitter or a circumferential beam emitter. By selecting a target head 01 of different shapes, it can be determined whether the beam is directional or circumferential. The beam emitter position of the circumferential beam emitter is on the circumferential side wall of the target head (such as Figure 2 shown).

[0031] The beam extension device applied to an open micro-focus ray tube of the present invention is used to position the tube head of the open micro-focus ray tube through the positioning window 09, and is installed on the tube head of the open micro-focus ray tube through the connecting flange 10; the ray beam of the open micro-focus ray tube passes through the positioning window 09, the sleeve 05, and the central pipeline 03 in sequence, hits the center of the target head 01, and is emitted through the target head 01. The present invention extends the beam exit position of the open micro-focus ray tube to generate x-rays. The present invention can adjust the distance between the beam exit position of the target head 01 and the tube head of the open micro-focus ray tube according to the length and thickness of the central pipeline 03, and use different detection spaces.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that modifying the technical solutions described in the aforementioned embodiments, or replacing some or all of the technical features therein by equivalents, does not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
