High-integration-level coaxial double-indexing universal milling head device

The invention discloses a high-integration coaxial double-indexing universal milling head device. The device comprises a C-axis indexing adjusting module, a C-axis input module, a middle module, an A-axis output module and an A-axis indexing adjusting module. The milling head integrates the advantages of various existing milling heads, high structural integration is achieved, the machining space of a lathe cannot be excessively compressed, and the machining range of the lathe is expanded. During working, power of a machine tool spindle is transmitted to the output shaft through meshing of the input shaft bevel gear and the first intermediate shaft bevel gear and meshing of the second intermediate shaft bevel gear and the output shaft bevel gear, 360-degree transposition of a C shaft is achieved through meshing of a mouse chain wheel, and 250-degree transposition of an A shaft is achieved through a worm gear and a worm. The output shaft of the device and the output shaft of the lathe are on the same axis, so t
