AI Technical Summary
Traditional rotary platforms are prone to deviations in rotation angle due to the misalignment of the turntable and bearings.
The design employs a bevel gear meshing with a bevel gear disk. A drive motor rotates the bevel gear, achieving a concentric connection between the bevel gear disk and the turntable. Combined with an optocoupler sensor, the turntable's reference position is calibrated to ensure accurate rotation angle.
This effectively ensures the concentricity of the turntable and the rotary bearing, avoids rotation angle deviation, and achieves precise angle control.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotating platform technology, and in particular to a high concentricity rotating platform. Background Technology
[0002] A rotary platform is a device used to adjust the position of an object. Traditionally, the turntable is placed directly on a bearing, and the motor outputs power to make the turntable rotate. In this way, if the turntable is not well concentric with the bearing, the rotation angle of the rotary platform is very easy to deviate.
[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a high concentricity rotating platform that ensures accurate rotation angles and prevents deviations.
[0005] The technical solution of this utility model is as follows: A high concentricity rotary platform is provided, comprising: a drive motor, a mounting base with a mounting groove, a conical bevel gear connected to the output shaft of the drive motor, and a rotary assembly mounted in the mounting groove; the rotary assembly includes: a rotary bearing, a turntable, and a bevel gear disk; the inner ring of the rotary bearing is connected to the bottom surface of the mounting groove, the bevel gear disk is connected to the outer ring of the bearing, the outer ring of the rotary bearing and the turntable are integrally formed, and the turntable is disposed outside the mounting groove; the conical bevel gear meshes with the bevel gear disk. When the drive motor operates, it drives the conical bevel gear to rotate. Because the conical bevel gear meshes with the bevel gear disk, the bevel gear disk rotates. Because the bevel gear disk is connected to the outer ring of the bearing, and the outer ring of the rotary bearing and the turntable are integrally formed, the turntable is driven to rotate. Since the turntable and the outer ring of the rotary bearing are integrally formed, the concentricity of the turntable and the rotary bearing can be effectively guaranteed, thereby ensuring accurate rotation angles and preventing deviations.
[0006] Furthermore, the high concentricity rotary platform also includes: a sensing plate mounted on the turntable, and an optocoupler mounted on the mounting base, wherein the rotation range of the sensing plate passes through the sensing area of the optocoupler. The optocoupler is used to sense the sensing plate, thereby calibrating the reference position of the turntable; when multiple optocouplers are distributed, the rotation angle of the turntable can be accurately determined in real time.
[0007] Furthermore, the conical bevel gear includes: a connecting shaft, and a bevel gear portion connected to one end of the connecting shaft; the other end of the connecting shaft is connected to the output shaft of the drive motor.
[0008] Furthermore, the high concentricity rotary platform also includes a connector, the two ends of which are respectively connected to a drive motor and a mounting base, a connecting shaft passing through the connector, and a bevel gear portion engaging with a bevel gear disc. The connector is used to connect the drive motor and the mounting base, allowing for a more rational product design.
[0009] Furthermore, the high concentricity rotary platform also includes a support bearing installed within the connector, the inner ring of which is fitted onto the connecting shaft. The support bearing is used to support the connecting shaft.
[0010] Furthermore, the high concentricity rotary platform also includes: a locking ring; one end of the connecting shaft is a plurality of claw plates, the plurality of claw plates forming an insertion groove; the output shaft is inserted into the insertion groove, and the locking ring is sleeved on the claw plates to connect the output shaft and the connecting shaft.
[0011] Furthermore, the high concentricity rotary platform also includes a dustproof ring disposed at the edge of the mounting groove, the dustproof ring being disposed below the turntable.
[0012] By adopting the above solution, this utility model provides a high concentricity rotary platform. A drive motor operates, causing conical bevel gears to rotate. Since the conical bevel gears mesh with the bevel gear disk, the bevel gear disk rotates. Because the bevel gear disk is connected to the outer ring of a rotary bearing, and the outer ring of the rotary bearing is integral with the turntable, the turntable is driven to rotate. Because the turntable and the outer ring of the rotary bearing are integral, the concentricity of the turntable and the rotary bearing can be effectively guaranteed, thus ensuring accurate rotation angles without deviation.

When the drive motor 10 operates, it drives the conical bevel gear to rotate. Because the conical bevel gear meshes with the bevel gear disk, the bevel gear disk rotates.

[0026] In this embodiment, the high concentricity rotary platform further includes a dustproof ring 27 disposed at the edge of the mounting groove 11, the dustproof ring 27 being located below the turntable 14.
[0027] In summary, this utility model provides a high concentricity rotary platform. A drive motor operates, causing a conical bevel gear to rotate. Because the conical bevel gear meshes with the bevel gear disc, the bevel gear disc rotates. Since the bevel gear disc is connected to the outer ring of a rotary bearing, and the outer ring of the rotary bearing is integral with the turntable, the turntable is driven to rotate. Because the turntable and the outer ring of the rotary bearing are integral, the concentricity of the turntable and the rotary bearing can be effectively guaranteed, thus ensuring accurate rotation angles without deviation.
