ツールアンクランプ装置。 In a numerically controlled machine tool in which the rotating shaft of the spindle drive motor is arranged concentrically on the axis of the spindle, the base end of the drawbar is fitted and supported inside the spindle via a disc spring so that it can move forward and backward. , fixing a first pressure receiving member that engages with the pressing member of the first lever of the tool unclamping link mechanism, and a base end portion of the main shaft located on the tool mounting end side when viewed from the first pressure receiving member; A second pressure receiving member that engages with the pressing member of the second lever of the link mechanism is fixed, and the first lever and the second lever are further connected via a connecting rod. A link mechanism for tool unclamping that urges the first pressure receiving member toward the second pressure receiving member is formed, and a drive device for generating unclamping force is connected to the input end of the link mechanism. Tool unclamp device for numerically controlled machine tools.
