Abstract

See full text

A clamping device (100) includes a first movable member (210) that is movable along an extending direction of a first body interior space (120), a disc spring (260), an annular spring (270), a spring (280) and a collet (300). A driving mechanism (400) has a second movable member (430) that moves along an extending direction of a second body interior space (130) with rotation of a rotary member (410). When the rotary member is rotated in one direction, the first movable member moves toward an oil-filled closed space (121) and the clamping device is set to a clamping mode that will hold a tool holder (510). On the other hand, when the rotary member is rotated in the opposite direction, the first movable member moves towards the side opposite of the oil-filled closed space and the clamping device is set to an unclamping mode that will release the tool holder.
