Large-feed-rate universal milling head device based on double electric control index plates

The invention discloses a large-feed-rate universal milling head device based on double electric control index plates. The device comprises a C-axis electric index plate, an input unit, a middle unit, an output unit and an A-axis electric index plate. Rotation of a milling cutter is achieved through cooperation of bevel gears, rotation of a shaft A and a shaft C is electrically controlled, when an electric control milling head works, power of a machine tool spindle is transmitted to an output shaft through meshing of an input bevel gear and a first intermediate bevel gear and meshing of a second intermediate bevel gear and an output bevel gear, and rotation of the shaft C is controlled through a shaft C self-locking stepping motor; the A-axis self-locking stepping motor is used for controlling A-axis transposition, meanwhile, the full-automatic fine machining device has the advantages of being simple and compact in structure, capable of designing the speed according to the transmission ratio of the bevel gear
