Abstract
A machine tool (10) has a spindle (11) for receiving a tool (15) for machining a workpiece (16). A mechanism (17) for clamping the workpiece (16) is also provided. Also provided is a changing mechanism (37) for a machining tool (29), which holds the machining tool (29) in a gripper hand (38) which it introduces laterally into a workpiece cavity (21) in such a way that it can be automatically coupled there to an adapter tool (32) carried by the spindle (11).
Claims12
A machine tool for machining a workpiece comprising
- a spindle with a spindle axis,
- an adaptor tool including an automatic coupling mechanism, the adaptor tool being operatively connected to the spindle,
- a workpiece having an opening in a wall thereof, which opening extends substantially perpendicularly to the spindle axis into a cavity of the workpiece,
- and a mechanism for clamping the workpiece,
- wherein a changing mechanism having a gripper hand for gripping a machining tool is provided, said machining tool having an automatic coupling mechanism, which gripper hand is arranged for inserting said machining tool substantially perpendicularly to said spindle axis through said opening into said workpiece cavity in such a way that said machining tool can be automatically coupled inside said workpiece cavity to the adapter tool carried by the spindle.

- a spindle with a spindle axis,
- an adaptor tool including an automatic coupling mechanism, the adaptor tool being operatively connected to the spindle,
- a workpiece having an opening in a wall thereof, which opening extends substantially perpendicularly to the spindle axis into a cavity of the workpiece,
- and a mechanism for clamping the workpiece,
- wherein a changing mechanism having a gripper hand for gripping a machining tool is provided, said machining tool having an automatic coupling mechanism, which gripper hand is arranged for inserting said machining tool substantially perpendicularly to said spindle axis through said opening into said workpiece cavity in such a way that said machining tool can be automatically coupled inside said workpiece cavity to the adapter tool carried by the spindle,
- wherein the gripper hand is arranged on a pivoting retaining arm which pivots the gripper hand, once pulled back out of the workpiece,
- wherein the retaining arm is arranged on a linear/pivot drive which additionally pivots the retaining arm to above the workpiece in constrainedly guided fashion during one segment of the retaining arm's linear stroke,
- wherein at least one sensor for monitoring a linear end position, and at least one sensor for monitoring a pivoted end position, are pivoted on the linear/pivot drive.
