Drilling and turning combined machine tool

The utility model relates to the technical field of hole machining, in particular to a drilling and turning combined machine tool which comprises a machine frame, a workpiece driving assembly and a machining assembly. The workpiece driving assembly is fixed to the rack and comprises a clamping disc used for fixing a workpiece and a first rotation driving device used for driving the clamping disc to rotate. The machining assembly and the workpiece driving assembly are oppositely arranged on the rack, and the machining assembly comprises a machining module, a first driving device used for driving the machining module to move in the first direction and a second driving device used for driving the machining module to move in the second direction. After one-time clamping, a plurality of stations can conduct drilling, outer diameter machining, inner hole roughness machining and the like on a workpiece, multi-procedure combined machining is achieved, a drilling machine and a lathe are integrated on one device, multi
