[0028] 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.

[0029] Reference Figure 1 , Figure 2 and Figure 3, the utility model provides an embodiment: a multi-angle support stand for industrial CT detection, including a base 1, a placement plate 3 is arranged on the upper side of the base 1, a servo motor 4 is fixedly connected to the top of the placement plate 3, a hollow disc 5 is rotatably connected to the top of the servo motor 4, the output end of the servo motor 4 penetrates the hollow disc 5 and is fixedly connected to a driving bevel gear 6, a plurality of screw rods 7 are rotatably connected to the inner side of the hollow disc 5 at equal intervals, a driven bevel gear 8 is fixedly connected to one side of the outer wall of the screw rod 7, and the plurality of driven bevel gears 8 are respectively meshed with the top of the driving bevel gear 6 at four sides, a convex plate 9 is threadedly connected to the outer side of the screw rod 7, a plurality of grooves 10 are equidistantly provided around the top of the hollow disc 5, the tops of the plurality of convex plates 9 respectively penetrate the corresponding grooves 10 and are fixedly connected with an arc clamping plate 11, an adjusting mechanism 2 is arranged inside the base 1, a plurality of slide rods 13 are fixedly connected to the inner side of the hollow disc 5 at equal intervals, and the two sides of the plurality of convex plates 9 are respectively slidably connected to the outer sides of the corresponding slide rods 13;

[0030] Specifically, the servo motor 4 can drive the active bevel gear 6 to rotate, and the active bevel gear 6 meshes with a plurality of driven bevel gears 8, so the driven bevel gear 8 will also rotate with the rotation of the active bevel gear 6. As the driven bevel gear 8 rotates, it will further drive the screw rod 7 connected thereto to rotate, and at this time, the convex plate 9 on the screw rod 7 will drive the arc clamping plate 11 to move forward and backward on the outside of the slide rod 13. This structural design enables the arc clamping plate 11 to accurately adjust its position to adapt to workpieces of different sizes, and can ensure that the workpiece will not shake during CT detection, thereby improving the accuracy of the detection result.

[0031] Reference Figure 1 and Figure 2 The adjusting mechanism 2 includes an open slot 201, which is provided at the middle of the top of the base 1, a servo motor 202 is fixedly connected to the right side of the inside of the open slot 201, a worm 203 is fixedly connected to the output end of the servo motor 202, a rotating rod 204 is rotatably connected to the inside of the open slot 201, a half worm gear 205 is fixedly connected to the outside of the rotating rod 204, the half worm gear 205 is meshedly connected to the worm 203, a connecting rod 206 is fixedly connected to the top of the half worm gear 205, the top of the connecting rod 206 is fixedly connected to the bottom of the placement plate 3, the left end of the worm 203 is rotatably connected to the left side of the inside of the open slot 201, and the adjusting mechanism 2 also includes a reinforcing rib 207, and two reinforcing ribs 207 are respectively fixedly connected to the left and right sides of the connecting rod 206;

[0032] Specifically, manually rotating the hollow disc 5 can make the workpiece to be tested rotate horizontally, and the servo motor 202 can drive the worm 203 to rotate, so that the half worm wheel 205 meshing with the worm 203 can also rotate accordingly. This unique meshing design enables the placement plate 3 to achieve the function of tilting left and right. The tilting of the placement plate 3 can make the workpiece to be tested on the upper side of the hollow disc 5 follow the tilt. This design enables the device to adapt to various complex shapes and sizes of workpieces to be tested, further enhancing the versatility and practicality of the device. When performing multi-angle detection, we use external CT equipment to scan the workpiece to be tested. Since the device can achieve multi-angle rotation and tilting of the workpiece to be tested, the CT equipment can capture more details and feature information, thereby improving the accuracy and reliability of the detection.

[0033] Reference Figure 1 A controller 14 is fixedly connected to the right side of the front end of the base 1. The controller 14 is electrically connected to the servo motor 202 and the servo motor 4 respectively. A protective cover 15 is provided on the outside of the controller 14. One side of the protective cover 15 is rotatably connected to the front end of the base 1.

[0034] Specifically, the operation of the servo motor 202 and the servo motor 4 can be controlled by the controller 14 , and the protective cover 15 can protect the controller 14 from being damaged by external factors.

[0035] Reference Figure 1 and Figure 2 , one side of the plurality of arc-shaped clamping plates 11 is fixedly connected with a rubber pad 12;

[0036] Specifically, the rubber pad 12 can further increase the friction between the workpiece to be measured and the arc-shaped clamping plate 11, so that the workpiece to be measured can be placed more stably.

[0037] Working principle: When using the device, first observe the size of the workpiece to be tested, and then place it in the middle of the top of the hollow disc 5. At this time, the servo motor 4 can drive the active bevel gear 6 to rotate, and the driven bevel gear 8 will rotate along with it due to the engagement with the active bevel gear 6, thereby driving the corresponding screw 7 to rotate. At this time, the convex plate 9 on the corresponding screw 7 will drive the arc clamping plate 11 to move back and forth on the outside of the slide rod 13, so that workpieces of different sizes can be limited and fixed. The workpiece is not easy to shake during the inspection, so as not to affect the accuracy of the industrial CT inspection results, which can meet the needs of users. When it is necessary to perform multi-angle inspection on the workpiece to be tested, rotating the hollow disc 5 can drive the workpiece to be tested to rotate horizontally, and then the servo motor 202 can drive the worm 203 to rotate. The half worm gear 205 will also rotate along with it due to the engagement with the worm 203, thereby driving the placement plate 3 to tilt left and right, and the hollow disc 5 on the upper side of the placement plate 3 will tilt left and right. At this time, the workpiece to be tested can be inspected at multiple angles through external CT equipment, thereby improving the practicality of the device.
