Machine for automatically drilling stephanoporate circular mould using the same drill

The invention discloses a porous drilling circular mold, which consists of a drill base, a workpiece fixing base, a workpiece moving handle, a workpiece moving frame, an electric motor, an aiguille speed changer, a step motor speed changer and an aiguilles/aiguilles. The invention is characterized in that one to five aiguilles are provided and are evenly distributed on the half lateral surface of the workpiece circular mold; the aiguille speed changer is provided with a servo motor which is connected with the aiguille speed changer; the step motor speed changer and the step motor connected with the step motor speed changer are arranged on the rotating shaft of the circular mold; the servo motor and the step motor are connected via cables and a servo motor controller and a step motor controller in a control box. The invention has the advantage of lower labor intensity and higher drilling efficiency, and effectively ensures better machining quality of the die holes of the circular die.
