Machine tool with a manipulator

Abstract

A machine tool ( 10 ) is provided with a workpiece carrier ( 19 ) for clamping a workpiece ( 18 ) to be machined and with a headstock (14) in which a rotary-driven tool spindle ( 15 ) is mounted into which tools ( 16 ) can be clamped for machining the workpieces ( 18 ). Further, a device ( 26 ) is provided for removing and holding the workpiece ( 18 ) that has been finished in the workpiece carrier ( 19 ) for further machining. The device ( 26 ) comprises a manipulator ( 27 ) for positioning a gripper ( 28 ) by which a workpiece ( 18 ) is removable that has been finished in the workpiece carrier ( 19 ), and a clamping station ( 29 ) into which the gripper ( 28 ) that holds the workpiece can be inserted (FIG. 1 ).

Therefore, what I claim, is:  
     
         1 . A machine tool, comprising 
 a workpiece carrier for clamping a workpiece to be machined,    a headstock mounting a rotary-driven tool spindle adapted to clamp in tools for machining the workpiece,    a manipulator equipped with a gripper for gripping a workpiece clamped into the workpiece carrier, and    a clamping station designed to clamp in the gripper with a workpiece hold by the gripper,    said manipulator adapted for removing said workpiece from the workpiece carrier and inserting the gripper into the clamping station.    
     
     
         2 . A machine tool as in  claim 1 , wherein the manipulator comprises a beam pivotably arranged about a vertical axis, the beam mounting the gripper pivotably about a rotation axis, said rotation axis running transversely with respect to the vertical axis.  
     
     
         3 . A machine tool as in  claim 2 , wherein the beam is vertically adjustable into the direction of the vertical axis.  
     
     
         4 . A machine tool as in  claim 1 , wherein the clamping station comprises clamping jaws for centering and holding the gripper, which clamping jaws are adapted to an outer contour of the gripper.  
     
     
         5 . A machine tool as in  claim 3 , wherein the clamping station comprises clamping jaws for centering and holding the gripper, which clamping jaws are adapted to an outer contour of the gripper.  
     
     
         6 . A machine tool as in  claim 1 , wherein the gripper comprises exchangeable jaws that are adapted to an outer contour of the workpiece.  
     
     
         7 . A machine tool as in  claim 2 , wherein the gripper comprises exchangeable jaws that are adapted to an outer contour of the workpiece.  
     
     
         8 . A machine tool as in  claim 1 , wherein the workpiece carrier comprises a clamping device that is transversely pivotable with respect to the vertical axis, such that the clamping device can position the workpiece into an orientation for machining of its side remote from the clamping device.  
     
     
         9 . A machine tool, comprising 
 a workpiece carrier for clamping a workpiece to be machined,    a headstock mounting a rotary-driven tool spindle to clamp in tools for machining the workpiece,    a manipulator equipped with a gripper, said gripper comprising exchangeable jaws adapted to an outer contour of the workpiece for gripping the workpiece, and    a clamping station comprising clamping jaws for centering and holding the gripper with a workpiece hold by the gripper,    said manipulator adapting for transferring said gripper between a position at the workpiece carrier and a position in the clamping station.    
     
     
         10 . A machine tool as in  claim 9 , wherein the clamping jaws of the clamping station are adapted to an outer contour of the gripper.  
     
     
         11 . A machine tool, comprising 
 a workpiece carrier for clamping a workpiece to be machined,    a headstock mounting a rotary-driven tool spindle to clamp in tools for machining the workpieces,    a manipulator equipped with a gripper for gripping a workpiece clamped into the workpiece carrier, and    a clamping station comprising clamping jaws adapted to an outer contour of the gripper,    said manipulator adapted for transferring said gripper between the workpiece carrier and the clamping station.    
     
     
         12 . A machine tool as in  claim 11 , wherein the gripper comprises exchangeable jaws adapted to an outer contour of the workpiece.
