する主軸工具着脱装置。[Claims for Utility Model Registration] A cylindrical main shaft rotatably supported on the main spindle head is inserted into a shaft hole so as to be able to move forward and backward in the axial direction of the main shaft, and by the forward and backward movement, a grip member is attached to one end of the main shaft. a push rod that fixes and releases the tool; and a push rod that is slidably fitted into the push rod and comes into contact with a stopper fixed to the push rod to transmit the elastic force of the clamping spring to the push rod so that the push rod is always moved in the tool fixing direction. It has a spring retainer that is pushed forward, and is movable in the direction of the spindle axis relative to the spindle head.
An unclamping cylinder that is normally positioned at a predetermined position by a spring force and that pushes the spring receiver in the direction of compression of the clamping spring to release the pressing force in the tool fixing direction; a push rod operating cylinder for pushing the push rod to a position where the gripping member releases the tool; an engaging member is integrally provided on the piston rod of the push rod operating cylinder; A spindle tool attachment/detachment device characterized in that an engagement portion that engages with a mating member is formed in a push rod.
