Embodiment Construction
[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0047] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relationship between various components under a certain posture (as shown in the accompanying drawings). The relative positional relationship, the movement situation, etc., if the specific posture changes, the directional indication also changes accordingly. ...

The present invention provides a turntable driving device, including a mounting seat; a turntable, the turntable is rotatably arranged on the mounting seat; at least one driving motor, the driving motor does not include an encoder, and is connected to the said mounting seat through a speed regulating structure a turntable drive connection for driving the turntable to rotate; and an angle detector connected with the driver of the drive motor for detecting the rotation angle of the turntable and directly controlling the turntable through the driver Start and stop of the drive motor. The technical solution of the present application, on the premise that the turntable driving device has a large transmission torque, overcomes the loss of accuracy when the speed regulating mechanism is worn, and also overcomes the influence of the accuracy of the speed regulating mechanism on the output accuracy of the entire turntable. The speed regulating mechanism can also obtain high-precision output, which improves the transmission control accuracy of the turntable drive equipment.
Description
technical field [0001] The present invention relates to the technical field of driving devices, in particular to a turntable driving device. Background technique [0002] The traditional turntable drive equipment includes three types of drive modes: direct drive motor direct drive, servo or direct drive motor plus speed control structure drive, and servo motor plus speed control structure plus angle sensor plus full closed-loop control system. [0003] First, the direct drive motor directly drives the rotor to realize the rotational movement of the rotor directly by the magnetic force, and then drives the turntable fixed on the rotor to rotate, and the rotation angle is directly fed back to the driver by the encoder; High-precision control of the rotation angle, there is no backlash in the rotation, but the torque of the direct drive motor is small, and there is no self-locking ability. In some occasions where self-locking is required, an external brake needs to be configure...
