Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, and in particular to an X-ray nondestructive testing device for detecting internal defects. Background Technology

[0002] Non-destructive testing (NDT) refers to a method of inspecting and testing the internal structure, state, and type, quantity, shape, nature, location, size, distribution, and changes of defects in mechanical materials without damaging or affecting their performance or internal structure. This is done by utilizing changes in thermal, acoustic, optical, electrical, and magnetic reactions caused by abnormalities or defects in the material's internal structure, using physical or chemical methods and modern technology and equipment.

[0003] The main reasons why X-ray inspection is widely used in non-destructive testing technology are: it can penetrate materials that visible light cannot penetrate; it has attenuation effects and attenuation laws in materials; it can cause photochemical effects, ionization effects and fluorescence phenomena in certain materials, and these effects will increase with the increase of X-ray intensity. X-ray flaw detection utilizes the difference in the degree of X-ray absorption due to different material thicknesses. By using X-ray radiography and real-time imaging with industrial television, internal defects in materials, components and welds, such as cracks, shrinkage cavities, porosity, slag inclusions, incomplete fusion, and incomplete penetration, can be revealed from the film and images to determine their location and extent.

[0004] In modern industrial production, the inspection of the internal quality of products is crucial. X-ray nondestructive testing (NDT) is an important inspection method that can detect internal defects without damaging the object being inspected. However, existing X-ray NDT internal defect detection devices have many shortcomings, affecting the accuracy and efficiency of the inspection. Traditional X-ray NDT devices may only be able to inspect at fixed positions and angles. For objects with complex shapes or large sizes, it is difficult to fully cover their internal structure, which can easily lead to missed defects and inaccurate test results, failing to meet diverse inspection needs. Therefore, we propose an X-ray NDT internal defect detection device to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this utility model, an X-ray non-destructive testing device for detecting internal defects includes a square housing 1. A rotary motor 7 is fixedly installed on the upper surface of the square housing 1. A rotating rod 8 is fixedly connected to the output end of the rotary motor 7. A square frame 9 is fixedly connected to the bottom end of the rotating rod 8. An electric push rod 10 is fixedly connected to the inner wall of the square frame 9. A connecting frame 11 is fixedly connected to the output end of the electric push rod 10. A high-resolution detector 12 and a high-power X-ray source 13 are fixedly installed on the outer surface of the connecting frame 11. A touch display screen 4 is fixedly installed on the right side of the square housing 1. A multi-core processor 5 and a control terminal 6 are fixedly connected to the right side of the square housing 1. The high-resolution detector 12 and the high-power X-ray source 13 are both electrically connected to the multi-core processor 5 through wires. The processor 5 and control terminal 6 are electrically connected to the touch display screen 4 via wires. The multi-core processor 5 has a high-speed data processing and image analysis system. It adopts high-performance multi-core processor 5 and parallel computing technology to quickly process the large amount of data collected by the detector. Through parallel computing, the data processing time is greatly shortened, and real-time analysis of detection data and image reconstruction are realized. The rotating motor 7 drives the rotating rod 8 and the square frame 9 to rotate, so that the high-resolution detector 12 and the high-power X-ray source 13 can perform multi-angle detection around the object being detected. At the same time, the position of the connecting frame 11 can be adjusted by the electric push rod 10, which further expands the detection range, can fully cover the internal structure of the object being detected, reduce the detection blind zone, and improve the accuracy of the detection results.

[0024] The front of the square housing 1 is hinged with an observation window 2, which is made of lead glass. Lead glass is made by adding a certain proportion of lead to ordinary glass, which has good radiation protection performance while maintaining a certain degree of transparency and aesthetics. Lead glass can effectively block X-rays, ensuring that the examiner will not be exposed to radiation damage when observing X-ray images. An electric cylinder 18 is fixedly installed on the bottom of the square housing 1 via a frame 21. The output end of the electric cylinder 18 is fixedly connected to a stage 19. Two circular columns 20 are fixedly connected to the bottom of the stage 19. The bottom end of each circular column 20 penetrates the square housing 1 and extends to the bottom of the square housing 1. The bottom of the square housing 1 has a circular hole that matches the circular column 20. The electric cylinder 18 can adjust the height of the stage 19 to facilitate the placement of objects of different sizes. The circular column 20 on the bottom surface of the platform 19 engages with the circular hole on the bottom surface of the square shell 1, ensuring the stability of the platform 19 during the lifting process. This design makes the placement of the object being tested more flexible and convenient, and can adapt to objects of different shapes and sizes.

[0025] A guide rail 14 is fixedly connected to the bottom surface of the square frame 9. A sliding rod 15 is slidably connected inside the guide rail 14. One end of the sliding rod 15 is fixedly connected to the outer surface of the connecting frame 11. When adjusting the position of the connecting frame 11, the sliding rod 15 can move within the guide rail 14 to ensure smoother horizontal movement of the connecting frame 11. A ring slide rail 16 is fixedly connected to the inner top wall of the square shell 1. A square rod 17 is slidably connected inside the ring slide rail 16. The bottom end of the square rod 17 is fixedly connected to the upper surface of the square frame 9. When the square frame 9 rotates, the square rod 17 can slide within the ring slide rail 16 to improve its movement stability. Multiple supporting square columns 3 are fixedly connected to the bottom surface of the square shell 1, providing stable support for the entire device and ensuring that the device will not affect the test results due to shaking during the testing process.

[0026] The working principle of this utility model is as follows:

[0027] After securing the device and connecting it to the power supply, open the observation window 2 and place the object to be inspected on the stage 19. The electric cylinder 18 can be used to move the stage 19 up and down to accommodate objects of varying sizes. Simultaneously, the electric push rod 10 can be activated to move the connecting frame 11 according to the size of the object, allowing it to move left and right to the appropriate position. Next, the object on the stage 19 is moved to a position level with the high-resolution detector 12 and the high-power X-ray source 13. Then, the rotary motor 7 can be activated to rotate the square frame 9 and the connecting frame 11. The system enables the connecting frame 11, high-resolution detector 12, and high-power X-ray source 13 to rotate, allowing for multi-angle detection around the object being inspected. The high-power X-ray source 13 emits X-rays that penetrate the object, and the high-resolution detector 12 clearly acquires internal image information of the object. The collected data is transmitted to the multi-core processor 5 in real time, and the data collected by the detector is quickly processed and analyzed. With the connection between the touch display screen 4, the multi-core processor 5, and the control terminal 6, an image of the internal structure of the object being inspected is generated, and defect information is identified.
