PURPOSE:To perform automatically a drilling work for a necessary diameter by standing plural drilling devices in parallel on a base stand and by moving to the position for drilling work with releasing the necessary lock of the drilling device by a jig truck. CONSTITUTION:Plural drilling devices No.1-4 are respectively provided in parallel movably in advancing the retreating in the axial Z direction, which equip on a york 3 the punch 5 moving vertically in the direction of the axial Y for a die 4 by the die 4 and a vertical driving device 7 on a base stand 1. A jig truck 10 is then provided movably in feeding in the direction of the axis X intersecting at right angles with the advancing the retreating direction Z of the drilling devices on the base stand 1 of the front of the drilling devices No.1-4. The feeding device 9, 12 moving selectively at jig truck 10 to the corresponding position to the respective drilling device, the advancing and tetreating motion mechanism 13, 15, 27 advancing the drilling device in the position corresponding to the jig truck 10 to the work position or retreating to the shunting position and the stopper to lock other drilling devices at the shunting position are provided. |
