摘要

An automatic tool changing arrangement for a machine tool in which a tool magazine nonrotatably supports tool heads. A spindle structure has a nonrotative housing with a sleeve rotatable and axially moveable therein. Cooperating elements of a bayonet latch on the tool head and one end of the sleeve are engageable and disengageable while the tool head is nonrotatively supported by the tool magazine by rotating the sleeve in the housing. Cooperating elements of clutch means on the housing and tool head are engageable and disengageable by axial movement of the sleeve in the housing while the bayonet latch is engaged. The sleeve may have a rotary spindle therein for driving rotary elements which may be provided in the tool head.
