摘要： A machine tool is provided with a tool turret, a turning apparatus which turns and positions a tool turret around a turning shaft which is orthogonal to an allocation shaft thereof, a carrier apparatus which carries in or carried out a work at a predetermined position of a peripheral edge portion of a moving region of the turret, and a work gripping device which is provided with an opening and closing pawls and an opening and closing mechanism thereof, and installed to a tool attaching portion of the turret. A transfer of the work to a carry-in position and a carry-out position of the work is carried out by utilizing a moving and positioning motion of the turret, an allocating rotation motion and a turning and positioning motion. The carry-in position and the unloading position of the work may be the same position or different positions, thereby to achieve a cost reduction of an apparatus which carries out the loading and unloading, and securely avoid an interference and a collision with a turret and a cutting tool table.

摘要： A work grip device which is installed to a tool turret, and a transfer method of a work in an inner portion of a lathe turning machine using the grip device are provided without arranging a drive source in the work grip device, and an electric wiring and a hydraulic pressure piping to a turret which moves and index rotates. The work grip device is provided with an opening and closing jaws which are driven so as to be opened and closed on the basis of a rotation of a tool motor. A holder of the work grip device is provided with an input shaft which is connected to a tool drive shaft within a turret head by the same structure as a rotary tool at a time of being attached to the tool turret, and is provided with a motion converting mechanism converting a forward and reverse rotation of the input shaft into an opening and closing motion of the opening and closing jaws of the grip device which is provided in the holder.
摘要翻译：本发明提供一种不需要在工作把持装置内配置驱动源的情况下，使用把持装置来安装在工具转台上的工件夹持装置以及车床的内部的工件的搬运方法，一个液压管道连接到一个移动和转位的转台上。工作夹持装置设有开启和闭合爪，所述开启和闭合爪基于工具电动机的旋转而被驱动以便打开和关闭。作业把持装置的保持架具备输入轴，该输入轴在安装于工具转台时通过与旋转工具相同的结构与转塔头内的工具驱动轴连接，转换机构将输入轴的正向和反向转动转换成设置在保持器中的夹持装置的打开和关闭夹爪的打开和关闭运动。
