Description

Technical Field

[0001] This utility model relates to the field of rotary platform technology, and in particular to a precision rotary platform. Background Technology

[0002] A rotary platform typically consists of a base and a rotating platform. To enable the rotating platform to rotate on the base, a rotating device is usually installed between the base and the rotating platform. This rotating device drives the rotating platform to rotate. However, existing rotary platforms have a large gap between the base and the rotating platform after the rotating device is installed. During use, dust particles in the air can enter the rotating device through the gap, increasing the damping of the rotating device and causing the rotation to be obstructed. This affects the precision of the precision rotary platform, so improvements are needed. Utility Model Content

[0003] The main objective of this invention is to provide a precision rotary platform, which aims to offer a precision rotary platform with high precision and smooth operation.

[0004] To achieve the above objectives, this utility model proposes a precision rotating platform, including a base, a turntable, and a turntable drive component. The turntable is located above the base and in contact with the base. The turntable drive component is located on one side of the base and is connected to the turntable in a transmission manner. The turntable drive component drives the turntable to rotate on the base.

[0005] Specifically, the turntable drive includes a drive motor, a slide rail is provided on one side of the base, a slider is provided on the slide rail, a rotating component is provided on the slider, the motor shaft end of the drive motor is connected to the rotating component, and a connecting block is provided on one side of the turntable to connect with the rotating component. The turntable is connected to the rotating component on the base through the connecting block.

[0006] Specifically, the rotating component includes a connecting seat, a first bearing, and a second bearing. The first bearing and the second bearing are stacked on the upper end of the connecting seat. The middle part of the connecting block is provided with a connecting hole corresponding to the first bearing and the second bearing. The connecting block contacts the first bearing and the second bearing through the connecting hole.

[0007] Specifically, the connecting block includes a mounting part and a connecting part. The mounting part is provided with a mounting hole for connecting with the turntable. The connecting hole is located in the middle of the connecting part. The connecting part is provided with an adjustment notch. A locking hole is provided at the adjustment notch. The diameter of the connecting hole is adjusted by the locking hole.

[0008] Specifically, the rotating component is provided with an assembly hole, the motor shaft end of the drive motor is connected to the assembly hole through a connecting screw, and the extension direction of the slide rail is the same as the axial direction of the connecting screw.

[0009] Specifically, the lower surface of the turntable is provided with a rotating groove, and a rotating bearing is provided in the rotating groove.

[0010] This utility model's technical solution involves placing the turntable drive component on one side of the base, thereby reducing the connection gap between the turntable and the base. This also improves the smoothness of the turntable's rotation on the base, prevents dust particles from causing rotational resistance to the turntable during prolonged use, and enhances the stability of the rotation angle of the rotating platform.

[0017] like Figures 1 to 2 As shown, a precision rotary platform includes a base 10, a turntable 11, and a turntable 11 drive component. The turntable 11 is positioned above and in contact with the base 10. The turntable 11 drive component is located on one side of the base 10 and is convexly connected to the turntable 11, driving the turntable 11 to rotate on the base 10. By mounting the turntable 11 on the base 10, and driving the turntable 11 through the turntable 11 drive component, the turntable 11 rotates on the base 10, thereby achieving rotation.

[0018] The drive mechanism for the turntable 11 includes a drive motor 12. A slide rail 13 is provided on one side of the base 10, a slider 14 is provided on the slide rail 13, and a rotating component is provided on the slider 14. The motor shaft of the drive motor 12 is connected to the rotating component. A connecting block 18 connected to the rotating component is provided on one side of the turntable 11. The turntable is connected to the rotating component on the base 10 via the connecting block 18. In this embodiment, by providing a slide rail 13 on the base 10, the drive motor 12 is connected to the rotating component, and the slider 14 drives the rotating component to move along the slide rail 13. At the same time, the rotating component is connected to the turntable 11 via the connecting block 18. Since the connecting block 18 is fixed on the turntable 11, the turntable 11 can only rotate, thus realizing the rotation of the turntable 11.

[0019] The rotating component includes a connecting seat 15, a first bearing 16, and a second bearing 17. The first bearing 16 and the second bearing 17 are stacked on the upper end of the connecting seat 15. A connecting hole 20 corresponding to the first bearing 16 and the second bearing 17 is provided in the middle of the connecting block 18. The connecting block 18 contacts the first bearing 16 and the second bearing 17 through the connecting hole 20. In this embodiment, the first bearing 16 and the second bearing 17 are provided on the upper end of the connecting seat 15. The first bearing 16 and the second bearing 17 are in contact with each other with zero distance between them. The first bearing 16 and the second bearing 17 cooperate to facilitate the transmission of the connecting block 18, thereby realizing the rotation of the turntable 11.

[0020] The connecting block 18 includes a mounting part and a connecting part. The mounting part is provided with a mounting hole 19 for connecting with the turntable 11. The connecting hole 20 is located in the middle of the connecting part. The connecting part is provided with an adjustment notch 21, and a locking hole 22 is provided at the adjustment notch 21. The diameter of the connecting hole 20 is adjusted by the locking hole 22. In this embodiment, the mounting part of the connecting block 18 is provided with a mounting hole 19, which facilitates the installation of the connecting block 18 onto the turntable 11 by passing a fixing screw through the mounting hole 19. Then, the locking hole 22 locks the adjustment notch 21, thereby changing the diameter of the connecting hole 20, so as to achieve a stable connection between the connecting block 18 and the first bearing 16 and the second bearing 17.

[0021] The rotating component has mounting holes, and the motor shaft end of the drive motor 12 is connected to the mounting holes via a connecting screw 23. The extension direction of the slide rail 13 is the same as the axial direction of the connecting screw 23. In this embodiment, mounting holes are provided on the rotating component to facilitate the connection of the motor shaft end of the drive motor 12, thereby enabling the drive of the rotating component.

[0022] A rotation groove is provided on the lower surface of the turntable 11, and a rotation bearing 24 is provided in the rotation groove. In this embodiment, a rotation groove is provided on the lower surface of the turntable 11, and a rotation bearing 24 is provided in the rotation groove, thereby improving the smoothness of the rotation of the turntable 11.
