    摘要： A multispindle-head machine tool has a column, a plurality of multispindle heads each having a plurality of tools and an engaging member and an annular feed passageway supporting the multispindle heads for circulatory movement therealong. The annular feed passageway includes a pair of upper and lower fixed guide members supported on the column, and a movable guide member movable back and forth horizontally for interconnecting ends of the upper and lower fixed guide members near a machining position. A rotary actuator is provided together with a feed mechanism disposed around the annular feed passageway and movable to circulate along the annular feed passageway by the rotary actuator for moving the multispindle heads along the annular feed passageway. An actuator unit is mounted on the column in association with the movable guide member for positioning one of the multispindle heads which is held on the movable guide member in the machining position, and rotating the tools of one of the multispindle heads. A jig table is mounted on a side of the column and horizontally movable back and forth. The jig table includes an attachment jig for supporting a workpiece to be machined by the tools of one of the multispindle heads.

    摘要翻译： 多头头机床具有一列，多个多轴头，每个具有多个工具和接合构件，以及环形进给通道，其支撑多个主轴用于沿其循环运动。 环形进给通道包括支撑在柱上的一对上下固定引导构件和可水平移动的可移动引导构件，用于使上下固定引导构件的端部在加工位置附近相互连接。 旋转致动器与设置在环形进给通道周围的进给机构一起设置，并且可通过旋转致动器沿着环形进给通道循环，以便沿着环形进给通道移动多个主轴头。 致动器单元与可移动引导构件相关联地安装在列上，用于定位在加工位置中保持在可移动引导构件上的多个主轴头中的一个，并且旋转多个主轴头中的一个的工具。 夹具台安装在立柱的一侧并可水平移动。 夹具台包括用于通过多轴头中的一个的工具来支撑待加工的工件的附接夹具。
