[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a centering pre-centering device for industrial CT detection, comprising a rotating stage 1, the front and rear sides of the rotating stage 1 are fixedly connected with an L-shaped plate 3, the inner wall of the L-shaped plate 3 is fixedly connected with a hydraulic rod 4, the output ends of the two hydraulic rods 4 are fixedly connected with a mounting plate 5, the left and right sides of the top walls of the two mounting plates 5 are threaded with a threaded knob 6, the bottom ends of the two threaded knobs 6 are threaded with a cleaning shell 8, the left and right sides of the inner top walls of the two cleaning shells 8 are fixedly connected with a reset spring 9, the bottom ends of the multiple reset springs 9 are fixedly connected with a cleaning sponge brush 10, the adjacent sides of the two mounting plates 5 are fixedly installed with a push plate 11, the bottom wall of the rotating stage 1 is rotatably connected with a workbench 15, the inner wall of the rotating stage 1 is provided with a rotating assembly, and the left side of the top wall of the workbench 15 is provided with an adjustment mechanism 2;

[0034] Specifically, two hydraulic rods 3 drive two mounting plates 5 to move. The two mounting plates 5 tightly fix the cleaning shell 8 through two threaded knobs 6. When the mounting plates 5 move, the cleaning shell 8 also moves, driving the two cleaning sponge brushes 10 to move synchronously. These sponge brushes are soft in texture and can effectively remove dirt and dust on the surface of the rotating stage 1. In addition, the cleaning sponge brushes 10 can be replaced by simply turning the two threaded knobs 6. This design not only improves the flexibility of the device, but also avoids cross contamination that may occur during the cleaning process. When the sponge brush is worn or seriously contaminated, timely replacement is the key to ensuring the accuracy of the test results. In order to further adapt to objects to be detected of different sizes and shapes, the device is also equipped with two push plates 11. By adjusting the displacement of the push plate 11, the horizontal position of the object to be detected can be accurately adjusted to ensure that it remains stable on the rotating stage, thereby further improving the accuracy of the detection.

[0035] Reference Figure 1 and Figure 3 The adjusting mechanism 2 includes a housing 201 and a supporting assembly. The bottom wall of the housing 201 is fixedly connected to the left side of the top wall of the workbench 15. The supporting assembly is arranged on the right side of the housing 201. The inner bottom wall of the housing 201 is fixedly connected to a motor 202. The output end of the motor 202 is fixedly connected to a threaded rod 203. The outer wall of the threaded rod 203 is threadedly connected to a lifting plate 204. The front and rear sides of the housing 201 are fixedly connected to an adjusting plate 205. The right side of the bottom wall of the adjusting plate 205 is fixedly installed with a CT device 206.

[0036] Specifically, when the motor 202 is started, the threaded rod 203 starts to rotate. Since the inner wall of the lifting plate 204 is slidably connected to the vertical shell 201, its rotation is restricted, so the lifting plate 204 will perform lifting and lowering motion along the axial direction of the threaded rod 203. This design enables the lifting plate 204 to accurately control its height position. Next, the lifting plate 204 transmits its lifting and lowering motion to the adjusting plate 205 by connecting to the adjusting plate 205. The adjusting plate 205 is responsible for supporting and fixing the CT device 206, so when the height of the adjusting plate 205 changes, the height of the CT device 206 will also be adjusted accordingly. This height adjustment function enables the CT device 206 to adapt to the body shape and detection needs of different patients, thereby improving the flexibility and practicality of the device.

[0038] Specifically, by starting the motor 2 13, the gear 14 rotates, which in turn drives the rotating stage 1 to rotate, thereby achieving the purpose of changing the angle. The left side of the sliding block 208 is slidably connected to the slide groove 209, so that the sliding block 208 and the support rod 207 achieve the purpose of supporting the adjustment plate 205. By connecting the support frame 20, the device is more stable when working.

[0039] Reference Figure 1 , Figure 2 and Figure 3 A control switch 17 is fixedly connected to the front end of the left side of the top wall of the workbench 15, and the control switch 17 is electrically connected to the hydraulic rod 4, the motor 2 13, the motor 1 202 and the CT device 206 respectively; a protective shell 18 is provided on the rear side of the control switch 17, and the bottom of the protective shell 18 is rotatably connected to the top wall of the workbench 15;

[0040] Specifically, through the control switch 17 electrically connected to the hydraulic rod 4, motor 2 13, motor 1 202 and CT device 206 respectively, the control switch 17 can complete the opening and closing of the device, and the protective shell 18 can complete the protection of the control switch 17 and prevent accidental touch.

[0042] Specifically, the two rubber rings 7 can protect the mounting plate 5 to prevent excessive rotation of the threaded knob 6, the two rubber pads 12 can protect the object to be detected, the scale 21 makes it easy to observe the height adjustment distance, and the two limit plates 19 can limit the displacement of the lifting plate 204 to avoid damage to the motor 202.

[0043] Working principle: before starting the test, by starting the two hydraulic rods 3, the two mounting plates 5 drive the cleaning shell 8 fixedly installed by the two threaded knobs 6 to move, so that the two cleaning sponge brushes 10 are moved together, so that the surface of the rotating stage 1 can be cleaned, and the cleaning sponge brushes 10 can be replaced by rotating the two threaded knobs 6, thereby improving the flexibility of the device and avoiding dirt from contaminating the surface of the object to be tested and affecting the test results, thereby ensuring the accuracy of the test, and then by the displacement of the two push plates 11, the horizontal position of the object to be tested can be adjusted, and by starting the motor 2 13, the gear 14 is rotated, and through the meshing connection with the gear seat 16, the gear 14 drives the rotating stage 1 to adjust the angle, and by starting the motor 1 202, the threaded rod 203 is driven, and then when the inner wall of the vertical shell 201 limits the rotation of the lifting plate 204, the lifting plate 204 drives the adjustment plate 205 to adjust the height, so that the CT device 206 completes the adjustment, thereby facilitating the detection work of the device, thereby improving the flexibility of the device.
