模块化主轴单元
摘要：
本发明公开一种模块化主轴单元，用以在机械加工工具中组成多主轴机械加工头(36、37、49)，该主轴单元(01、30、54)包含至少一驱动主轴(02)，可用来装设工具(37)或工具载体(51、52)；且主轴单元(01、30、54)包含模块化壳体(08、31)，以装设驱动主轴(02)于其中，从而可以自由地转动并可以轴向移动。而模块化壳体(08、31)可与其他模块化壳体(08、31)共同连接在机械加工头(36、47、49)上；其中主轴单元(01、30、54)包含至少一驱动马达(03)，使配置于其上的驱动主轴(02)能受其驱动而以旋转方式作动，且驱动马达(03)的中心轴线和驱动主轴(02)的中心轴线共轴延伸而定义一元件中心轴(07)；其中主轴单元(01、30、54)包含至少一轴向致动装置(05)，使配置于其上的驱动主轴(02)能够顺着元件中心轴(07)方向而轴向转动；其中轴向致动装置(05)的中心轴线和驱动主轴(02)的中心轴线共轴延伸，驱动马达(03)装设在模块化壳体(08、31)中而可轴向位移，且由驱动轴向致动装置(05)，驱动马达(03)可在模块化壳体(08、31)中，与驱动主轴(02)一起顺着该元件中心轴(07)方向而轴向位移。本发明的模块化主轴单元，结构简单，使得主轴单元能够彼此非常接近的一起安装在机械加工头上。
摘要（英）：

The invention relates to a modular spindle unit for forming a multispindle machining head (36, 47, 49) for a machine tool, wherein the spindle unit (01, 30, 54) comprises at least one drive spindle (02) to which a tool (37) or tool carrier (51, 52) can be attached, and wherein the spindle unit (01, 30, 54) comprises a module housing (08, 31) in which the drive spindle (02) is mounted such that it can rotate freely and be axially displaced. Together with further module housings (08, 31), the module housing (08, 31) can be fastened to the machining head (36, 47, 49), wherein the spindle unit (01, 30, 54) comprises at least one drive motor (03) which can be used to drive an associated drive spindle (02) in rotation, and wherein the centre axis of the drive motor (03) and the centre axis of the drive spindle (02) run coaxially and define a centre axis (07) of the unit. The spindle unit (01, 30, 54) comprises at least one axial actuating device (05) which can be used to axially drive an associated drive spindle (02) in the direction of the centre axis (07) of the unit, wherein the centre axis of at least one axial actuating device (05) and the centre axis (07) of the unit run coaxially. The drive motor (03) is mounted in the module housing (08, 31) such that it can be displaced axially, and may be axially displaced in the module housing (08, 31) by the axial actuating device (05), together with the drive spindle (02), being driven along the centre axis (07) of the unit.
