Description

Technical Field

[0001] This utility model relates to the field of open microfocus X-ray tube technology, and in particular to a beam extension device for use in open microfocus X-ray tubes. Background Technology

[0002] Due to the advantages of open-tube microfocus X-ray tubes in imaging geometric sharpness, magnification, scattered radiation attenuation, and detail detection sensitivity, they can compensate for the shortcomings of conventional X-ray imaging equipment. They have wide applications in digital real-time imaging (DR) inspection and industrial CT inspection, including the inspection of electronic chips, circuit boards, aircraft engines, weapon components, complex assemblies, castings, and forgings. Application areas cover the detection of minute defects in composite materials, plastics, light metals, and fiber-reinforced materials in the aerospace and electronics industries.

[0003] Current open-type microfocus X-ray tubes generate X-rays directly from the target surface at the tube tip. Due to the tube tip's structure, the X-rays are emitted in a 160° fan shape directly at the target surface at the tube tip. If inspecting the interior of a component, the internal space of the component needs to be larger than the overall size of the microfocus X-ray tube tip. Limited by the external dimensions of open-tube microfocus X-ray tubes, the tube tip cannot penetrate slender cylindrical components, leading to difficulties, low efficiency, and high costs when inspecting such components. Furthermore, current open-type microfocus X-ray tubes and their functional products are expensive, resulting in high financial and time costs during repairs.

[0004] Therefore, there is a need for open-tube microfocus X-ray tubes that can penetrate into thin tubes for detection without affecting the detection quality and reducing costs. Utility Model Content

[0005] This invention primarily addresses the technical problems of difficulty in detecting slender cylindrical components, low detection efficiency, and high detection costs associated with current open-tube microfocus X-ray tubes. It proposes a beam extension device for open-tube microfocus X-ray tubes, which can extend into slender cylindrical or tubular components, increasing the detection length of the open-tube microfocus X-ray tube head and enabling the detection of slender cylindrical or tubular components.

[0006] This utility model provides a beam extension device for open microfocus X-ray tubes, including: a target head, an outer sleeve, a central pipeline, an adjustment block, a sleeve, a base, and a connecting flange;

[0007] The input end of the central pipeline is inserted into the base, and the output end of the central pipeline is equipped with a target head; an outer sleeve is fitted over the central pipeline; a coolant gap is left between the outer sleeve and the central pipeline;

[0008] The input end of the central pipeline is connected to the positioning window via a sleeve; the sleeve is placed inside the base; the positioning window is fixed at the center of the base.

[0009] A connecting flange is fixedly installed at the end of the base; the positioning window is located at the center of the connecting flange.

[0010] The positioning window is used for positioning with the tube head of the open microfocus X-ray tube, and the connecting flange is used for connecting with the tube head of the open microfocus X-ray tube.

[0011] The base is provided with multiple adjustment blocks around its circumference; the multiple adjustment blocks abut against the outer sleeve.

[0012] Preferably, the base is provided with two water pipe connectors;

[0013] The water pipe joint is connected to the coolant via a gap.

[0014] Preferably, a cable window is provided on the base;

[0015] The cable window is electrically connected to the cable, which is placed inside the base and wrapped around the outside of the sleeve.

[0016] Preferably, the base is provided with a plurality of adjustment holes in its circumference, and the adjustment block is placed in the corresponding adjustment hole.

[0017] Preferably, the target head is a target head with directional beam emission or circumferential beam emission.

[0018] This invention provides a beam extension device for open-type microfocus X-ray tubes. Installed at the tube head, the central tube has a slender shape and a small diameter, allowing it to extend into slender cylindrical or tubular components. This increases the detection length of the open-type microfocus X-ray tube head, extending the beam output and enabling the inspection of slender cylindrical or tubular components. Open-type microfocus X-ray tubes equipped with this beam extension device are widely applicable to the inspection of thin tubes, thin cylinders, and other workpieces requiring extended beam output, or workpieces with limited inspection space, thus expanding the applicable inspection range of open-type microfocus X-ray tubes. It also improves inspection efficiency and reduces inspection costs. This invention has high compatibility and wider applicability. Attached Figure Description

[0022] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0023] like Figure 1-2 As shown in the figure, the present invention provides a beam extension device for an open microfocus X-ray tube, comprising: a target head 01, an outer sleeve 02, a central tube 03, an adjustment block 04, a sleeve 05, a base 06, and a connecting flange 10.

[0024] The input end of the central conduit 03 is inserted into the base 06, and the output end of the central conduit 03 is equipped with a target head 01; an outer sleeve 02 is fitted over the central conduit 03. Correspondingly, the input end of the outer sleeve 02 is also inserted into the base 06. The central conduit 03 and the outer sleeve 02 are detachably mounted in the base 06, and different lengths of the outer sleeve 02 and the central conduit 03 can be selected to extend the beam to different exit positions.

[0025] A coolant gap is left between the outer casing 02 and the central pipe 03. Two water pipe connectors 07 are provided on the base 06; the water pipe connectors 07 are connected to the coolant gap. Coolant is poured into the coolant gap through the water pipe connectors 07; the electron beam channel inside is cooled by water through the coolant gap between the outer casing 02 and the central pipe 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; the positioning window 09 is fixed at the center of the base 06.

[0027] A connecting flange 10 is fixedly installed at the end of the base 06; the positioning window 09 is located at the center of the connecting flange 10. The positioning window 09 is used to position the tube head of the open microfocus X-ray tube, and the connecting flange 10 is used to connect to the tube head of the open microfocus 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 microfocus X-ray tube.

[0028] The base 06 has multiple adjustment blocks 04 arranged circumferentially; the multiple adjustment blocks 04 abut against the outer casing 02. Specifically, the base 06 has multiple adjustment holes arranged circumferentially, and the adjustment blocks 04 are placed in the corresponding adjustment holes. By inserting into the adjustment holes, the adjustment blocks 04 are adjusted to adjust the outer casing 02 and the central tube 03, so that the electron beam inside can hit the center of the target head 01.

[0029] A cable window 08 is provided on the base 06; the cable window 08 is electrically connected to a cable, which is placed inside the base 06 and wound around the outside of the sleeve 05 to form a coil, without contact between the cable and the sleeve 05. The direction of the electron beam is adjusted by adjusting the operating parameters of the cable.

[0030] The target head 01 can be either a directional or circumferential beam emission head. By selecting different shapes of target heads 01, the directional or circumferential beam emission can be determined. For circumferential beam emission targets, the beam emission position is on the circumferential sidewall of the target head (e.g., Figure 2 (As shown).

[0031] This invention relates to a beam extension device for open-type microfocus X-ray tubes. In use, the device is positioned with the tube head of the open-type microfocus X-ray tube via a positioning window 09, and is installed on the tube head via a connecting flange 10. The X-ray beam from the open-type microfocus X-ray tube passes sequentially through the positioning window 09, sleeve 05, and central conduit 03, striking the center of the target head 01, and exiting through the target head 01. This invention extends the beam exit position of the open-type microfocus X-ray tube, enabling it to generate X-rays. This invention allows adjustment of the distance between the beam exit position of the target head 01 and the tube head of the open-type microfocus X-ray tube according to the length and thickness of the central conduit 03, enabling the use of different detection spaces.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
