Description

Technical Field

[0001] The utility model relates to a focal length adjusting device for a panel of a DR detection device with high stability, belonging to the technical field of DR detection devices. Background Technique

[0002] The DR detection device is a technology for nondestructive testing using X-rays, which is widely used in medical, industrial and other fields. It is a device that exposes a digital imaging plate with X-rays or γ-rays and converts the collected signals into digital signals. It can convert these signals into digital images in a computer and display, observe and evaluate them on a display.

[0003] Chinese Patent Publication (Publication No.: CN 220120742 U) discloses a centering device for an X-ray detection device, including a frame for positioning and installing the X-ray detection device. A first adjustment mechanism for adjusting the longitudinal position of the workpiece according to the detection requirements is arranged in the frame. Above the first adjustment mechanism, there is a second adjustment mechanism for placing the workpiece and adjusting the transverse position of the workpiece according to the detection requirements. The utility model is convenient to position the emission end of the X-ray detection device through the central hole, and according to the position of the detection part required by the workpiece to be detected, the transverse position of the workpiece is changed by the operation of the second motor, and the longitudinal position of the workpiece is changed by the operation of the first motor, so as to reduce the intervention of manual work in the detection work and improve the efficiency of the detection work;

[0004] Although the above device can complete the detection of each part of the workpiece to be detected, due to the lack of a device for limiting the position of the workpiece, the position of the workpiece may shift when adjusting the detection position of the workpiece, resulting in inaccurate detection data. And modern DR devices are usually equipped with automatic exposure control technology, which can automatically adjust the focal length according to preset parameters to achieve an ideal exposure effect. However, due to the relatively fixed position of the focal length, the focal length range may not be adjustable, so that the detection range is relatively fixed, which is difficult to meet the usage requirements of users and reduces the practicability of the device.

[0005] Therefore, a focal length adjusting device for a panel of a DR detection device with high stability is proposed. Content of the Utility Model

[0036] When the utility model is working: First, drive the pull rod 206 to move outward through the handle 207. The pull rod 206 drives the clamp 205 to move outward. The clamp 205 squeezes the telescopic rod 203 and the return spring 204, causing the telescopic rod 203 to be compressed and the return spring 204 to deform. Place the workpiece to be detected on the top of the imaging plate 4. Then release the handle 207.

[0037] When it is necessary to adjust the DR detection device body 5, drive the first threaded rod 302 to rotate through the output end of the servo motor 301. The first threaded rod 302 drives the first threaded sleeve 303 to move up and down through the action of threaded connection. The first threaded sleeve 303 drives the welding rod 304 and the support table 305 to move up and down, thereby adjusting the up and down position of the DR detection device body 5. Drive the moving frame 307 to move back and forth through the output end of the cylinder 306. The moving frame 307 drives the adjustment frame 308 to move back and forth, thereby adjusting the front and back position of the DR detection device body 5. Drive the second threaded rod 310 to rotate through the output end of the drive motor 309. The second threaded rod 310 drives the second threaded sleeve 311 to move left and right through the action of threaded connection. The second threaded sleeve 311 drives the mounting table 312 and the DR detection device body 5 to move left and right, thereby adjusting the left and right position of the DR detection device body 5. Through the adjustment of the position up, down, left, right, front, and back, the focal length range of the DR detection device body 5 is adjusted and expanded, improving the practicability of the device.
