摘要： A turret tool holder, having means capable of easily avoiding unnecessary free rotation of a turret, is provided. When a linearly movable shaft is moved toward a turret head section by driving a servomotor, an annular movable coupling element arranged in the turret begins to disengage from an annular fixed coupling element fixed to a support. While the movable coupling member is still engaged with the fixed coupling member, clutch teeth of a clutch member are engaged with other clutch teeth. Therefore, even when the annular movable coupling element is disengaged from the annular fixed coupling element, the turret is prevented from freely rotating by the engaged clutch teeth.
摘要翻译：提供了具有能够容易地避免转台不必要的自由旋转的装置的转塔刀架。当通过驱动伺服电动机使可线性移动的轴向转台头部移动时，布置在转台中的环形可移动联接元件开始脱离固定到支撑件的环形固定联接元件。在可动联接部件仍然与固定联接部件接合的同时，离合器部件的离合器齿与其他离合器齿接合。因此，即使当环形可动联接元件从环形固定联接元件脱离时，通过啮合的离合器齿也防止转动架自由旋转。

摘要： To provide a tool post for a machine tool that can smoothly detach an engaging member in a side of a supporting member and an engaging member in a side of tool, the engaging members engaging in accordance with the movement of the tool. A first driving force transmission part (51) is disposed between an attachment part turning transmission shaft (90) located in a side of a tool post body (11) and a tool attachment part (15) located in a side of a first turning driving force transmission shaft (81). The first driving force transmission part (51) transmits rotary driving force from a side of the attachment part turning transmission shaft (90) to the side of the first turning driving force transmission shaft (81). The first driving force transmission part (51) includes a groove (97a), a tenon shaped protrusion (92), and protrusions (93a, 93b). The groove (97a) is formed on a tip of a slide shaft (97) of the attachment part turning transmission shaft (90). The tenon shaped protrusion (92) is formed in the first turning driving force transmission shaft (81) and detachably engages with the groove (97a). The protrusions (93a, 93b) once releases an engaging posture by pressing the groove (97a) that is biased to the engaging posture in an disengaging state when the tool is in the middle of the movement to a predetermined position.
摘要翻译：本发明提供一种能够顺利地将支承部件侧的卡合部件和工具侧的卡合部件分离的机床用工具支柱，该卡合部件随着工具的移动而卡合。第一驱动力传递部（51）配置在位于刀架主体（11）侧的安装部回转用传动轴（90）与位于第一回转驱动侧的工具安装部（15）之间力传递轴（81）。第一驱动力传递部51将旋转驱动力从安装部回转传动轴90侧传递到第一回转驱动力传递轴81侧。第一驱动力传递部件51包括凹槽97a，榫头状突起92和突起93a，93b。凹槽（97a）形成在连接部件转动传动轴（90）的滑动轴（97）的末端上。榫头形突起92形成在第一转动驱动力传递轴81中并且可拆卸地与槽97a接合。当工具处于移动的中间位置时，突起（93a，93b）通过按压处于分离状态的接合姿势的凹槽（97a）而释放接合姿势。
