Loading rotation device based on cam indexer

The invention provides a loading rotation device based on a cam indexer. The loading rotation device comprises a bottom frame, the cam indexer, a driving motor, a rotary loading table and a controller. The cam divider is fixed on the underframe; an output shaft of the driving motor is connected with an input shaft at one end of the cam divider; the controller is arranged on the bottom frame, and the driving motor is connected with the controller. Intermittent rotary motion is carried out through the cam indexer, the cam shaft and the output turret are in meshing transmission, and compared with traditional intermittent mechanisms such as a grooved wheel and a ratchet wheel, transmission is stable, action is accurate, the output segmentation precision is high, the high-speed performance is good, other locking elements are not needed at all, and the randomly determined dynamic-static ratio and segmentation number can be achieved; the rotation angle of the rotary objective table is ensured to be accurate; under t
