[0049] The technical solutions of the present invention will be further specifically described below through specific embodiments in conjunction with the accompanying drawings:

[0050] Embodiment 1: Refer to Figures 1 to 11 As shown, a friction-driven multi-ring rotating stage includes a chassis 1 and a stage body 3 provided on the chassis 1. The stage body 3 rotates on the chassis 1, and a driving device 5 for driving the rotation of the stage body 3 is provided on the chassis 1;

[0051] A moving device 2 for driving the movement of the chassis 1 is fixedly provided on the chassis 1; in this embodiment, a total of 6 groups of driving devices 2 are provided. The moving device includes a moving motor 22, and a moving wheel 221 is provided at the output end of the moving motor 22;

[0052] The stage body 3 is provided on the chassis 1. The stage body 3 includes a central stage 31. A plurality of outer ring turntables are provided in the circumferential direction of the central stage 31. Both the outer ring turntables and the central stage 31 are provided with annular driving tracks 4; the number and width of the outer ring turntables are not limited and can be set according to actual situations. In this embodiment, the outer ring turntables are specifically set as a second-ring turntable 32 and an outer ring turntable 33; a middle turntable 311 is fixedly provided at the central position of the bottom of the central stage 31, and a central support table 14 that rotates in cooperation with the middle turntable 311 is provided on the chassis 1; annular support frames 12 are provided at the bottoms of the central stage 31, the second-ring turntable 32, and the outer ring turntable 33. Support rollers 13 are provided on the upper surface of the chassis 1, and the support frames 12 are supported on the support rollers 13. The support frames 12 play a supporting role for the stage body 3, so that the support frames 12 can rotate on the support rollers 13 when the stage body 1 rotates;

[0053] The driving device 5 is fixedly arranged on the chassis 1, and the driving device 5 cooperates with the driving track 4; the driving device 5 includes a steel frame 51 slidably arranged on the chassis 1, a driving motor 52 and a pressing device are arranged on the steel frame 51, and a driving wheel 521 is connected to the output end of the driving motor 52; the pressing device includes a pressing wheel 53 and an elastic component 54, and the pressing wheel 53 is slidably arranged on the steel frame 51; one end of the elastic component 54 is connected to the steel frame 51, and the other end of the elastic component 54 is connected to the pressing wheel 53; the pressing wheel 53 and the driving wheel 521 are respectively arranged on both sides of the driving track 4, the elastic component 54 has elastic potential energy, and the elastic component 54 pushes the pressing wheel 53 to fit with the driving track 4.

[0054] Specifically, a slider mounting frame 511 arranged along the width direction of the driving track 4 is arranged on the chassis 1, the slider mounting frame 511 is arranged along the width direction of the driving track 4, a linear guide rail 512 is arranged on the slider mounting frame 511, and linear guide grooves 513 matched with the linear guide rail 512 are arranged on both sides of the steel frame 51, and the steel frame 51 can slide along the slider mounting frame 51 in the width direction of the driving track 4.

[0055] Specifically, the specific structure on the steel frame 51 is that a pressing plate 55 is fixedly arranged on the steel frame 51, a pressing plate sliding groove 551 is arranged on the pressing plate 55, support sliding plates 561 are arranged on both sides in the width direction of the pressing wheel support 56, and the support sliding plates 561 slide in the pressing plate sliding groove 551. The arrangement direction along the pressing plate sliding groove 551 is the same as the arrangement direction of the slider mounting frame 511. The cooperation between the support sliding plates 561 and the pressing plate sliding groove 551 enables the pressing wheel support 56 to slide on the pressing plate 55, and the pressing wheel 53 is arranged on the pressing wheel support 56; one end of the elastic component 54 is fixedly connected to the steel frame 51, and the other end of the elastic component 54 is connected to the pressing wheel support 56.

[0056] In this embodiment, a driving device 5, a central stage 31, a second-ring turntable 32 and an outer-ring turntable 33 are installed on the chassis 1. The moving motor 22 on the chassis 1 rotates to drive the moving wheel 221 to rotate, so that the chassis 1 can drive the overall friction-driven multi-ring rotating stage to move, which can meet the requirement of the movement of the stage body 3 during the performance and effectively improve the performance effect.

[0057] Driving tracks 4 are arranged at the bottoms of the central stage 31, the second-ring turntable 32 and the outer-ring turntable 33. A plurality of driving devices 5 are arranged below each driving track 4. The driving devices 5 at the bottoms of the central stage 31, the second-ring turntable 32 and the outer-ring turntable 33 cooperate with the driving tracks 4 below them, so that the central stage 31, the second-ring turntable 32 and the outer-ring turntable 33 can rotate independently, and a variable performing space can be provided.

[0058] As Figure 6As shown in the figure, when the driving device 5 and the driving track 4 are friction-driven, the driving motor 52 drives the driving wheel 521 to rotate. Frictional transmission occurs between the driving wheel 521 and the driving track 4, and the rotation of the driving wheel 521 drives the driving track 4 to rotate. The pressing wheel 53 is acted on by the elastic component 54 and presses against the other side of the driving track 4 relative to the driving wheel 521. When the driving wheel 521 wears due to friction with the driving track 4, the radius of the driving wheel 521 decreases. At this time, the frictional force between the driving wheel 521 and the driving track 4 decreases, and the frictional driving force of the driving wheel 521 on the driving track 4 weakens. At this time, the end of the elastic component 54 away from the pressing wheel 53 pushes the steel frame 51 to move to the right along the linear guide 512. After the steel frame 51 moves to the right, it drives the driving motor 52 and the driving wheel 521 to move to the right, so that the driving wheel 521 comes into contact with the driving track 4 again. That is to say, through the cooperation of the pressing wheel 53, the pressing plate 55, the pressing wheel bracket 56, the steel frame 51 and the linear guide 512 cooperating with the steel frame 51, the pressing wheel 53 and the driving wheel 521 can be tightly clamped on both sides of the driving track 4, maintaining the clamping force between the driving wheel 521 and the driving track 4, so that the driving wheel 521 can automatically compensate for the gap generated by friction with the driving track 4. At the same time, the above structure has the characteristic of convenient installation. During installation, it only needs to clamp the pressing wheel 53 and the driving wheel 521 on both sides of the driving track 4, and there is no need to adjust the specific position of the steel frame 21 too much.

[0059] Embodiment 2: Refer to Figures 6 to 8 As shown in the figure, this embodiment is similar in structure to Embodiment 1. The difference is that specifically, two elastic components 54 are provided, which are respectively arranged at both ends of the pressing wheel bracket 56 in the length direction. The pressing wheel 53 is arranged at the middle position between the two elastic components 54. The structure of the elastic component 54 is as follows: The elastic component 54 includes a slide rod 541 and a pressing spring 542. There is a bracket hole on the pressing wheel bracket 56. One end of the slide rod 541 is slidably arranged in the bracket hole, and the other end of the slide rod 541 is fixedly arranged on the steel frame 51. An abutting ring 543 is arranged on the side wall of the end of the slide rod 541 away from the pressing wheel bracket 56. One end of the pressing spring 542 abuts against the abutting ring 543, and the other end of the pressing spring 542 abuts against the pressing wheel bracket 56. In addition, the abutting ring 543 in this embodiment is a nut threadedly connected to the slide rod 541. By adjusting the position of the nut, the abutting force of the pressing spring 542 against the pressing wheel bracket 56 can be adjusted, so as to adjust the clamping force between the pressing wheel 53 and the driving wheel 521. Even after the abutting force of the pressing spring 542 decreases after being used for a period of time, by rotating the nut, the abutting force of the pressing spring 542 can be increased, which greatly facilitates the maintenance of the driving device 5.

[0060] In this embodiment, two elastic components 54 are provided, so that the pressing wheel 53 can be more stably abutted against the driving track 4 by the acting force of the pressing spring 542. At the same time, the setting of the two elastic components 54 also makes the driving wheel 521 more sensitive to compensate for wear.

[0061] Embodiment 3: Refer to Figures 1 to 10 As shown, this embodiment is similar in structure to Embodiment 1 or Embodiment 2; the difference is that, in order to facilitate the installation of the moving device 2 and facilitate the adjustment of the moving direction of the moving wheels; the structure of the moving device 2 is improved.
