Integrated servo main transmission mechanism for CNC (computer numerical control) turret punch press

The invention relates to the field of press structures and provides an integrated servo main transmission mechanism for a CNC (computer numerical control) turret punch press. By the use of the integrated servo main transmission mechanism which is delicate in structure, convenient to use and effective, at the premise of retaining original functions of a servo press, the problems caused by the use of a coupling are effectively solved. The integrated servo main transmission mechanism comprises a fixing frame, an eccentric shaft, a link, a slider and a servo motor; the servo motor comprises a stator serving as a shell, a rotor disposed within the stator and an output shaft penetrating the rotor; the upper portion of the fixing frame is provided with a transverse mounting hole; the stator is detachably connected into the transverse mounting hole; the eccentric shaft comprises an eccentric disc and a spindle integrally connected. The integrated servo main transmission mechanism is higher in acceleration and lower in energy consumption.
