とする工具アタチメント緊締装置。A device that is replaceably attached to the tip of the tool spindle head and tightens the tool attachment of a machine tool that performs cutting by controlling the relative position of the tool and the workpiece. multiple press stands,
A first holder that is recessed in the tip of the tool spindle head and that is hydraulically operated in the axial direction and integrally fixes a holder that loosely fits a plurality of clamp balls that engage and disengage with the pull stud that is inserted when replacing the tool attachment. A ball guide is formed on the inner circumferential surface of the holder in cooperation with the piston member and the press stand to cause the clamp ball to protrude and retract from the inner and outer circumferential surfaces of the holder, and is arranged concentrically with the first piston member and opposite to each other. A tool attachment tightening device characterized by comprising a plurality of tightening means including a second piston member that operates hydraulically in the axial direction in conjunction with the direction.
