The DR equipment clamping device, as a key auxiliary component of the DR system, is mainly used to fix the workpiece being inspected and the DR emission source, ensuring a relatively stable positional relationship between the two during imaging, thereby acquiring high-quality image data. In medical settings, it can accurately fix the area to be inspected on the patient, reducing image blurring caused by patient movement. In industrial fields, it can firmly clamp industrial parts, facilitating the inspection of internal defects. It plays a crucial role in improving the accuracy and reliability of DR inspection.

[0003] Traditional DR equipment clamping devices typically employ fixed structures or simple fixtures, which present the following problems: First, frequent disassembly and reassembly are required to adjust the angle, leading to cumbersome operation, low inspection efficiency, and difficulty in meeting multi-angle flaw detection needs. Second, insufficient clamping stability allows workpieces or emission sources to easily shift during inspection, affecting imaging accuracy. Furthermore, the structure is bulky and inconvenient to store, occupying a large space and hindering portability and rapid deployment. These problems not only increase the workload of operators but may also lead to errors in inspection results, affecting the reliability of industrial flaw detection or medical diagnosis. To address these issues, we propose a DR equipment clamping device. Utility Model Content

[0025] Furthermore, a through hole is provided on the outer arc surface of the lower workpiece clamp 3, and a thread is provided in the through hole. A connecting column is fixedly installed on one end face of the upper rod 4 and the lower rod 5, and a thread is provided on the outer arc surface of the connecting column.

[0027] Furthermore, through holes are provided on the side walls of the upper rod 4, lower rod 5, and middle rod 7, and the through holes of the three are connected by pin 6. The middle rod 7 can move laterally. In addition to serving as the axis for the lateral movement of the middle rod 7, pin 6 also plays the role of positioning and limiting the range of displacement.

This is a key node for realizing multi-angle adjustment of the DR emission source.

[0029] Furthermore, the other end of the steering component 9 is connected to the connecting component 11 by a pin 3 10. The connecting component 11 can move vertically, and the pin 3 10 ensures that the vertical displacement of the connecting component 11 is stably realized.

When the steering component 9 moves, the pin 3 10 ensures the vertical displacement of the connecting component 11 and avoids swaying or deviation.

[0030] Structural Description:

[0031] Upper workpiece clamp 1: The upper workpiece clamp 1 is located at the top of the workpiece clamp and is an important component for fixing the workpiece. Its bottom surface cooperates with the lower workpiece clamp 3 to clamp the workpiece together. Its shape and size are designed to fit the part of the workpiece to be fixed. It is tightly connected to the lower workpiece clamp 3 by hexagon socket screw 2 to ensure that the workpiece is stable and does not shake during the inspection process.

[0032] Hex socket screw 12: Hex socket screw 12 is a connector that connects the upper workpiece clamp 1 and the lower workpiece clamp 3. It passes through the screw hole of the upper workpiece clamp 1 and is screwed into the corresponding screw hole of the lower workpiece clamp 3. It provides a fastening force with its own thread structure, so that the two are firmly connected, thereby stabilizing the workpiece and ensuring the positional accuracy of the workpiece during inspection.

[0033] Workpiece lower clamp 3: The workpiece lower clamp 3 is located at the lower part of the workpiece clamp. The outer arc surface is provided with a threaded through hole for connection. It is set opposite to the workpiece upper clamp 1. The workpiece is placed between the two. It is threadedly connected to the upper rod 4 and the lower rod 5, which not only fixes the workpiece, but also serves as the connection node between the connecting rod assembly and the workpiece clamp, providing support for the stability of the entire device.

[0034] Upper rod 4: Upper rod 4 is an important part of the connecting rod assembly. It is located next to and fixedly installed with lower rod 5. One end face of it is provided with a threaded connecting post for threaded connection with the lower workpiece clamp 3. At the same time, it is connected to lower rod 5 and middle rod 7 through pin 6, providing a basis for rotation and lateral displacement of middle rod 7, thereby realizing the adjustment of DR emission source angle.

[0035] Lower rod 5: Lower rod 5 works in conjunction with upper rod 4. It also has a threaded connecting column fixed on one end face, which is threaded to the lower workpiece clamp 3. Together with upper rod 4, it supports middle rod 7 and is connected by pin 6, so that middle rod 7 can rotate and move laterally between the two, providing structural support for adjusting the angle of DR emission source.

[0036] Pin 6: Pin 6 passes through the through hole in the side wall of the upper rod 4, lower rod 5 and middle rod 7, connecting the three together. It serves as the axis of rotation and displacement, enabling the middle rod 7 to move laterally with the upper rod 4 and lower rod 5 as support. It is a key component for realizing the flexible adjustment of the linkage assembly and is crucial for the angle adjustment of the DR emission source.

[0037] Middle rod 7: The middle rod 7 is located between the upper rod 4 and the lower rod 5 and is rotatably connected by pin 6. Its other end is provided with a slot for installing the steering component 9. It can make lateral displacement. In conjunction with the steering component 9 and the connecting component 11, it can realize multi-angle adjustment of the DR emission source. It is one of the core components of the linkage assembly to achieve flexible adjustment.

[0038] Pin 2 8: Pin 2 8 connects the steering component 9 and the central rod 7, allowing the steering component 9 to rotate and move laterally within the slot of the central rod 7. It ensures a stable connection between the steering component 9 and the central rod 7, while allowing relative movement between them. This connection method provides more flexibility for multi-angle adjustment of the DR transmitter.

[0039] Steering component 9: Steering component 9 is located in the slot of the middle rod 7 and has rotating holes on both sides. It is connected to the middle rod 7 through pin 8 and can move laterally. At the same time, its rotating holes are rotatably connected to the connecting component 11. Steering component 9 plays the role of changing the direction of displacement, converting the lateral displacement of the middle rod 7 into the vertical displacement of the connecting component 11, and assisting in adjusting the angle of the DR emission source.

[0040] Pin 310: Pin 310 connects the steering component 9 and the connecting component 11, allowing the connecting component 11 to rotate and move vertically within the rotation hole of the steering component 9. This ensures the reliability and flexibility of the connection between the steering component 9 and the connecting component 11, and realizes the vertical displacement adjustment of the DR transmitter.

[0041] Connector 11: Connector 11 is located in the rotating hole of the steering component 9. The bottom surface is fixed with a threaded connecting post for threaded connection with the upper clamp 12. It can be vertically displaced under the drive of the steering component 9, thereby adjusting the position of the DR transmitter clamp and ultimately realizing the adjustment of the vertical angle of the DR transmitter.

[0042] Upper clamp 12: The upper clamp 12 is the upper structure of the DR transmitter clamp. The outer arc surface has a threaded through hole. It cooperates with the lower clamp 14 and is connected by an internal hexagonal screw 13 to clamp the DR transmitter together. At the same time, it is connected to the connector 11 by threads and can be adjusted in position by the linkage assembly to change the angle of the DR transmitter.

[0043] Hex socket screw 213: Hex socket screw 213 is used to connect the upper clamp 12 and the lower clamp 14, and firmly clamp the DR emission source between the two. It has a similar function to hex socket screw 12. Through threaded fastening, it ensures the stability of the DR emission source during the detection process and prevents it from shaking and affecting the detection results.

[0044] Lower clamp 14: The lower clamp 14 is located at the lower part of the DR emitter clamp and is set opposite to the upper clamp 12. Together with the upper clamp 12, it clamps the DR emitter with hexagon socket screws 13, providing stable support and fixation for the DR emitter and ensuring that it maintains the correct position and angle during testing.

[0045] Working principle: The workpiece is placed between the upper workpiece clamp 1 and the lower workpiece clamp 3, and tightened with hex socket screw 2. The threaded fastening force makes the upper and lower workpiece clamps fit tightly and firmly hold the workpiece. Similarly, the DR emission source is placed between the upper clamp 12 and the lower clamp 14 and fixed by hex socket screw 23. This ensures that the workpiece and the DR emission source will not shake during the detection process, thus ensuring the stability and accuracy of the imaging.

[0046] When the angle of the DR transmitter needs to be adjusted, the linkage assembly is operated. Since the upper rod 4, lower rod 5, and middle rod 7 are connected by pin 6, and the through holes on the side walls of the three rods allow the middle rod 7 to move laterally, it can be pushed or pulled. It can move laterally with the upper rod 4 and lower rod 5 as support. The steering component 9 in the slot at the other end of the middle rod 7 is connected to the middle rod 7 by pin 8. The lateral displacement of the middle rod 7 drives the steering component 9 to adjust laterally. The connecting component 11 in the rotating holes on both sides of the steering component 9, driven by the steering component 9, achieves vertical displacement through pin 10. The connecting post on the bottom of the connecting component 11 is threaded to the upper clamp 12. Its vertical displacement causes the upper clamp 12 and the lower clamp 14 connected to it to drive the DR transmitter to change the angle in the vertical direction. Through this cooperation of the linkage assembly and the pin assembly, the angle of the DR transmitter can be quickly adjusted without disassembly, meeting the needs of multi-angle flaw detection and improving detection efficiency.

[0047] When not in use, the upper rod 4, lower rod 5, middle rod 7, and other rods can be flexibly folded up by loosening the connecting parts of each pin, making the overall structure compact, saving storage space, and making it easy to carry and store. When in use, the components can be easily unfolded and connected according to the working principle described above.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
