[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4As shown, this utility model provides an intelligent guide-type wheel cage precision positioning device, including a bracket 1. A drive mechanism 4 is installed on one side of the bracket 1, and a cage assembly 3 is installed on one side of the drive mechanism 4. A positioning mechanism 2 is installed on the top side of the cage assembly 3. The positioning mechanism 2 includes a fixed frame 21. A second gear 210 is rotatably connected to the inner side of the fixed frame 21. A threaded rod 23 is fixedly connected to the middle of the second gear 210. The two ends of the threaded rod 23 pass through the two sides of the fixed frame 21 respectively. Moving blocks 24 are threadedly connected to both sides of the middle of the threaded rod 23. A guide plate 28 is fixedly connected to one end of the moving block 24. A rotating rod 27 is rotatably connected to one side of the guide plate 28. One end of the rotating rod 27 is fixedly connected to the guide plate 28. A positioning plate 212 is fixedly connected to the outside of the rotating rod 27. A push plate 214 is fixedly connected to the outside of the rotating rod 27. An electric push rod 26 is rotatably connected to one end of the push plate 214. A fixing block 25 is rotatably connected to one end of the electric push rod 26. One end of the fixing block 25 is fixedly connected to one side of the guide plate 28. An anti-slip pad 211 is fixedly connected to one side of the positioning plate 212. A guide rod 29 is fixedly connected to the side of the fixed frame 21. The outside of the guide rod 29 is slidably connected to the moving block 24. A first motor 213 is fixedly connected to one side of the fixed frame 21. A first gear 22 is fixedly connected to the output end of the first motor 213 through one side of the fixed frame 21. The first gear 22 meshes with a second gear 210.

[0024] When the cage assembly 3 moves, the first motor 213 drives the first gear 22 to rotate, and the meshing second gear 210 rotates accordingly, driving the threaded rod 23 to rotate. The threaded moving block 24 moves, and at the same time, the moving block 24 slides outside the guide rod 29. The fixed moving block 24 makes linear motion, driving the two guide plates 28 to move, so that the two guide plates 28 clamp the two sides of the bracket 1, restricting the lateral movement of the cage assembly 3, thereby maintaining the stable movement of the cage assembly 3 during the up and down movement. The electric push rod 26 drives one end of the push plate 214 to move, and the other end of the push plate 214 rotates around the rotating rod 27 as a fixed point, driving the rotating rod 27 to rotate. One end of the positioning plate 212 moves to abut against the side of the bracket 1. The anti-slip pad 211 can increase the friction between the positioning plate 212 and the bracket 1, and brake quickly when the cage assembly 3 reaches the target position, so that it stops accurately and achieves precise positioning.

[0025] Example 2: Figure 1 and Figure 4As shown, the drive mechanism 4 includes a connecting plate 41. One side of the connecting plate 41 is fixedly connected to one side of the positioning mechanism 2. A second motor 44 is fixedly connected to one side of the connecting plate 41. The output end of the second motor 44 passes through the connecting plate 41 and is fixedly connected to a drive gear 46. One side of the drive gear 46 meshes with a drive rack 43. One side of the drive rack 43 is fixedly connected to the bracket 1. A guide bearing 45 is slidably connected to the other side of the drive rack 43. One end of the guide bearing 45 is rotatably connected to one side of the connecting plate 41. A guide wheel 42 is rotatably connected to the side of the connecting plate 41. The outer side of the guide wheel 42 is movably connected to the bracket 1.

[0026] The overall effect of this embodiment is that the second motor 44 drives the drive gear 46 to rotate, the drive gear 46 moves on one side of the meshing drive rack 43, and drives the connecting plate 41 to move. At the same time, the guide bearing 45 rotates on the other side of the drive rack 43, thereby positioning the movement of the connecting plate 41. The movement of the connecting plate 41 drives the cage assembly 3 to move, thereby controlling the lifting and lowering of the cage assembly 3. During the lifting and lowering of the cage assembly 3, multiple guide wheels 42 are provided on the side of the connecting plate 41 to guide the movement of the connecting plate 41.

[0027] The operating method and working principle of this device are as follows: The second motor 44 drives the drive gear 46 to rotate. The drive gear 46 moves on one side of the drive rack 43, which in turn moves the connecting plate 41, thereby controlling the lifting and lowering of the cage assembly 3. The side of the connecting plate 41 is provided with multiple guide wheels 42, which can guide the movement of the connecting plate 41. The first motor 213 drives the first gear 22 to rotate, and the second gear 210 rotates accordingly, which drives the threaded rod 23 to rotate. The moving block 24 moves, so that the two guide plates 28 clamp the two sides of the bracket 1, restricting the lateral movement of the cage assembly 3. The electric push rod 26 drives one end of the push plate 214 to move. The other end of the push plate 214 rotates around the rotating rod 27 as a fixed point, which drives the rotating rod 27 to rotate. One end of the positioning plate 212 moves to abut against the side of the bracket 1 and brakes when the cage assembly 3 reaches the target position.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
