Description

Technical Field

[0001] The utility model belongs to the field of nondestructive testing, and particularly relates to an industrial X-ray detection device. Background Art

[0002] X-ray computed tomography (CT) uses radiation sources such as X-rays or gamma rays to perform internal imaging of objects in a non-destructive manner. It has the advantages of strong penetration and non-destruction, and is widely used in the field of industrial non-destructive testing to ensure product quality, safety and reliability.

[0003] Industrial X-ray detection devices play an important role in the field of non-destructive testing, but there are still some disadvantages. For example, in some X-ray detection devices, these devices include a C-arm, where the ray generator and the ray receiver are located at opposite ends of the C-arm. The C-arm can move relative to the object through continuous rotation angles to obtain detection information from multiple angles. However, due to the limitations of the C-arm movement mechanism, especially in the arrangement of the C-arm structure and the rotation path, there are situations where some internal structures cannot be fully irradiated and imaged due to occlusion or angle problems, which may result in certain angles or regions becoming "blind spots" in the detection field of view. The existence of such blind spots may miss some defects or details, affecting the integrity and accuracy of the detection. Summary of the Utility Model

[0004] In order to overcome the above technical defects, the utility model provides an industrial X-ray detection device to solve the problems involved in the background art.

[0029] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, some technical features well known to the art are not described to avoid confusion with the present utility model.

[0030] Refer to the attached Figures 1 to 3 , an industrial X-ray detection device, comprising: a working surface 100, a detection component and a fixing component.

[0031] The working surface 100 is located inside a protective lead room, effectively isolating radiation. Operators can, through pre-adjusting relevant measurement parameters and / or computer remote control, not enter the working surface 100 when the detection device is operating, protecting the operators and the surrounding environment from the harm of X-rays.

[0032] The detection component includes a column 210 installed on the working surface 100, a first mounting plate 220 installed on the column 210, a first rotating device 230 arranged on the first mounting plate 220, a C-shaped arm 240 arranged at the output end of the first rotating device 230, and a ray generator 250 and a ray receiver 260 respectively installed at two opposite ends of the C-shaped arm 240; designed in this way, the first rotating device 230 drives the C-shaped arm 240 to rotate, allowing the ray generator 250 and the ray receiver 260 to rotate around a central point at multiple angles driven by the C-shaped arm 240. This means that the workpiece can be irradiated and imaged from more directions, greatly broadening the detection perspective.

[0033] The fixing assembly includes a second rotating device 310 arranged on the working surface 100, a rotating mounting plate 320 mounted on the second rotating device 310, and a clamp mechanism arranged on the rotating mounting plate 320 and suitable for fixing the workpiece to be detected. By driving the rotation of the rotating mounting plate 320 through the second rotating device 310, the angle of the clamp mechanism itself can be adjusted, providing more scanning path options for the C-arm 240 and further reducing the detection blind area.

[0034] The clamp mechanism includes: two mounting brackets 330, two clamping blocks 340, and at least one third rotating device 350; the mounting brackets 330 are respectively mounted on the rotating mounting plate 320; the two clamping blocks 340 are arranged oppositely and are respectively rotatably mounted on the mounting brackets 330 through bearings, and the shape of the clamping blocks 340 is adapted to the outer contour of the workpiece to be detected; the third rotating device 350 is connected to one of the clamping blocks 340 and is suitable for driving the clamping block 340 to rotate. Since the workpiece to be detected is a rigid structure, the synchronous rotation of the two clamps is realized through the transmission torque of the workpiece to be detected, and then the rotation of the workpiece to be detected is realized, which means that the workpiece to be detected can fine-tune its posture without detaching from the fixture, so as to achieve almost all-round detection coverage, and even the fine parts of the complex internal structure of the workpiece to be detected can be fully irradiated and imaged.

[0035] The first rotating device 230, the second rotating device 310, and the third rotating device 350 all include a driving source and a transmission mechanism, where the driving source can be a hydraulic power source, a pneumatic power source, or a motor, and the transmission mechanism can be in forms such as gear transmission, chain transmission, and drive shaft transmission. It can be understood that both the driving source and the transmission mechanism are prior arts and will not be specifically introduced here.

[0036] Through the collaborative work of the multiple rotation mechanisms, full-angle detection of the workpiece to be detected is achieved, greatly improving the integrity and accuracy of the detection. It solves the problem of the visual field blind area existing in traditional X-ray detection equipment and is particularly suitable for the detection of workpieces with complex shapes and fine internal structures.

[0037] In a further embodiment, the clamping block 340 is made of a hard elastic material, or a hard elastic layer is provided on the inner surface of the clamping block 340, and the hard elastic material can be, but is not limited to, silicone rubber, polyurethane, and fluororubber. Through the clamping surface formed by the hard elastic material, while maintaining sufficient hardness to firmly fix the workpiece, its elastic characteristics can be used to adapt to the surfaces of workpieces with different shapes and sizes, ensuring that even on irregular or deformable workpieces, a tight fit can be formed, reducing image blurring or misjudgment caused by workpiece movement during the detection process.

[0038] In a further embodiment, the rotating mounting plate 320 is provided with grooves 321 distributed in an array, and a protrusion engaging with the grooves 321 is provided at the bottom of the mounting frame 330. Through the engaging mechanism of the grooves 321 and the protrusions, the accuracy and stability of the mounting frame 330 on the rotating mounting plate 320 can be ensured. Moreover, the operator can adjust the position of the mounting frame 330 on the rotating mounting plate 320 to adjust the two clamping blocks 340 to meet the clamping requirements of different workpieces to be detected.

[0039] In a further embodiment, a guide rail 211 is provided on the column 210, and the first mounting plate 220 is slidably mounted on the guide rail 211 and is adapted to adjust the height of the C-arm 240 relative to the working surface 100. The height adjustment method of the C-arm 240 can be manual adjustment and fixed by a pin, or can be automatic adjustment controlled by a lifting cylinder or a linear module. By adjusting the height of the C-arm 240, the detection device can adapt to workpieces of different sizes and heights, improving the versatility and flexibility of the detection device.

[0040] In a further embodiment, the C-arm 240 includes: a first support arm 241 adapted to mount the ray generator 250, a second support arm 242 adapted to mount the ray receiver 260, and a connecting arm 243 connecting the first support arm 241 and the second support arm 242 and connected to the output end of the first rotating device 230. Moreover, the distance from the first support arm 241 to the first rotating mounting device is greater than the distance from the second support arm 242 to the output end of the first rotating device 230. That is to say, the distance between the ray generator 250 and the workpiece to be detected is greater than the distance between the ray receiver 260 and the workpiece to be detected. When the angle of the ray generator 250 remains unchanged, a larger area of the object to be detected can be penetrated, further reducing the field of view blind area.

[0041] In a further embodiment, since the distances of the first support arm 241 and the second support arm 242 from the mounting position of the C-arm 240 are different, and the weights of the ray generator 250 and the ray receiver 260 are different, the center of gravity of the C-arm 240, the ray generator 250, and the ray receiver 260 is not located on the rotation center axis of the C-arm 240. Therefore, a counterweight is provided on the first support arm 241 and / or the second support arm 242 to adjust the mass distribution of each part, ensure that the C-arm 240 can maintain a good balance state, improve the stability of the rotation of the C-arm 240, and further improve the detection accuracy of the detection device.

[0042] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present utility model will not separately describe various possible combination manners.
