Automatic turntable driving structure

The invention discloses an automatic turntable driving structure. The automatic turntable driving structure comprises a vertically-arranged central shaft and a turntable rotatably arranged on the central shaft, a revolution gear driving the turntable to rotate is arranged in the center of the turntable, the revolution gear and the upper end of the central shaft are fixed, the revolution gear is driven by a revolution drive motor through a driving gear in a meshing mode, the driving gear is arranged on an output shaft of the revolution drive motor to be meshed with the revolution gear, a work station A, a work station B and a work station C are evenly distributed on the turntable in the circumferential direction, a vertical rotary shaft is arranged on each work station, an autoroatation chain wheel is arranged at the bottom end of each rotary shaft, an autoroatation drive motor is arranged on the turntable, and the autoroatation drive motor drives the autoroatation chain wheels on the three work stations to rotate through a chain on a chain wheel set. The driving structure is obviously simplified, and production cost is lowered.
