[0031] like Figures 1 to 4 The diagram illustrates an embodiment of the present invention, relating to a motor rotation structure, comprising a rotating disk 10, a hollow rotating shaft 20, a ball bearing 11, a first locking nut 12, a second locking nut 13, a base 30, and a power mechanism 40. The rotating disk 10 and the hollow rotating shaft 20 are integrally formed and connected, with a first positioning hole 14 in the center of the rotating disk 10. The hollow rotating shaft 20 has a second positioning hole 21 in the center, communicating with the first positioning hole 14. The ball bearing 11 is sleeved on the outside of the hollow rotating shaft 20. The first locking nut 12 and the second locking nut 13 are sequentially sleeved on the outside of the hollow rotating shaft 20, and are located below the ball bearing 11. The base 30 is connected to the bottom of the rotating disk 10. The power mechanism 40 is connected to one side of the base 30 and is used to drive the rotating disk 10 to rotate.
[0032] Furthermore, such as Figure 1 As shown, a stroke sensor 31 is provided on the side of the base 30. The stroke sensor 31 is used for position detection and limit control. A first protective cover 32 is provided on the upper surface of the stroke sensor 31 to protect the stroke sensor 31. Specifically, the stroke sensor 31 is connected to the rotating disk 10 to facilitate the detection of the position of the rotating disk 10 and limit the movement of the rotating disk 10; the first protective cover 32 better protects the stroke sensor 31.
[0033] Furthermore, such as Figure 4 As shown, a mounting groove 33 is provided on one side of the base 30, and a second protective cover 34 is provided above the mounting groove 33; one end of the power mechanism 40 is connected to the mounting groove 33. Specifically, the second protective cover 34 better protects the structure of the power mechanism 40 installed in the mounting groove 33, and is highly practical.
[0034] Furthermore, such as Figure 3 As shown, a bearing retaining ring 15 is provided above the ball bearing 11, and the bearing retaining ring 15 is located below the rotating disk 10. Specifically, the bearing retaining ring 15 ensures a stable connection between the rotating disk 10 and the ball bearing 11, guaranteeing the stable rotation of the hollow rotating shaft 20 within the ball bearing 11.
[0035] Furthermore, such as Figures 1 to 4As shown, the power mechanism 40 includes a stepper motor 41, a coupling 42, a ball screw 43, an angular contact bearing 50, a slider 44, and a guide rail 45. The stepper motor 41 is connected to one side of the coupling 42. One end of the ball screw 43 is connected to the coupling 42 and the stepper motor 41 in sequence, and the end of the ball screw 43 facing away from the stepper motor 41 is connected to the slider 44. The angular contact bearing 50 is located above the slider 44 and is connected to the bottom of the rotating disk 10. The guide rail 45 is connected to both sides of the slider 44 and is used to guide the movement of the slider 44. Specifically, through the driving cooperation between the stepper motor 41 and the coupling 42, the ball screw is driven to rotate, thereby driving the rotating disk 10 to rotate.
[0036] Furthermore, such as Figure 1 As shown, a motor mount 46 is provided on one side of the stepper motor 41. A bearing seat 47 is connected to the end of the motor mount 46 opposite to the stepper motor 41. The bearing seat 47 is connected to the ball screw 43 through a lead screw bearing 48. The coupling 42 is located inside the motor mount 46. Specifically, the motor mount 46 facilitates the connection between the stepper motor 41 and the coupling 42; the lead screw bearing ensures stable rotation of the ball screw 43, making it highly practical.
[0037] Furthermore, such as Figure 1 As shown, a manual adjustment wheel 49 is provided on one side of the stepper motor 41. Specifically, the manual adjustment wheel 49 is provided for convenient manual adjustment.
[0038] Furthermore, such as Figure 2 As shown, the guide rail 45 is a U-shaped track, and the guide rail 45 is fixed inside the mounting groove 33. Specifically, the stepper motor 41 operates, driving the ball screw 43 to rotate. The slider 44 moves in the direction of the guide rail 45 under the drive of the ball screw 43, thereby driving the angular contact bearing 50 to rotate the rotating disk 10.
[0039] Furthermore, such as Figure 4 As shown, the angular contact bearing 50 has clamping blocks 51 and pressure blocks 52 on both sides, which are located above the slider 44. The clamping blocks 51 have a protrusion 53 on their inner side, and the pressure blocks 52 have a groove 54 on their inner side, which engages with the protrusion 53. Specifically, the angular contact bearing 50 is effectively installed using the clamping blocks 51 and pressure blocks 52.
[0040] The working principle of this utility model is as follows:
[0041] The stepper motor 41 rotates, driving the ball screw to make linear motion via the coupling 42. The ball screw moves along the guide rail 45 via the slider 44, driving the angular contact bearing 50. The angular contact bearing 50 pushes the rotating disk 10, causing the rotating disk 10 to rotate, thus converting linear motion into rotational motion. At the same time, a first positioning hole 14 and a second positioning hole 21 are respectively provided in the rotating disk 10 and the hollow rotating shaft 20 to facilitate the storage of the wire harness from the middle and avoid messy placement of the wire harness. An integrated cross roller bearing is used as the ball bearing 11, which effectively improves the load-bearing capacity of this utility model and has a wide range of applications.
[0042] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
