Machine tool with automatic tool change

Abstract

Abstract MACHINE TOOL WITH TOOLS FIXED IN HOLDERS HAVING A ROTATABLE DRUM MAGAZINE FOR STORING A NUMBER OF HOLDERS. CONVEYING MEANS ARE PROVIDED FOR THE AUTOMATIC TRANSFER OF SAID HOLDERS IN A PREDETERMINED SEQUENCE BETWEEN THE DRUM MAGAZINE AND A WORKING POSITION OF THE TOOLS. THE HOLDERS ARE FIXED IN AN INTERCHANGEABLE MANNER ON THE DRUM MAGAZINE AND ON A HOLDER SUPPORT WHICH IS DISPOSED ON A SLIDE CAPABLE OF SLIDING IN ONE COORDINATE DIRECTION ON A GUIDING PART BY MEANS OF A DRIVE. THE CONVEYING MEAND HAS AT MOST A FIRST AND A SECOND TRANSFER PATH FORM SAID HOLDERS. THE FIRST PATH RUNS PARALLEL TO THE DIRECTION OF THE COORDINATE OF SAID SLIDE AND THE SECOND PATH IS ARRANGED ON SAID GUIDING PART BEING DIRECTED FROM SAID DRUM MAGAZINE MOUNTED ON SAID GUIDING PART AS A BEGINNING POINT TOWARDS A COMMON INTERSECTION POINT OF SAID FIRST AND SECOND TRANSFER PATHS AT WHICH POINT TWO HOLDERS FOR EXCHANGE MOVED IN COMMON BY A DRIVER, CHANGE THEIR TRANSFER PATH AND MUTUALLY CHANGE PLACES IN RELATION TO THE HOLDER SUPPORT AND ALSO TO THE DRIVER WHICH CAN BE MOVED ON THE SECOND TRANSFER PATH BY MEANS OF A SECOND DRIVE.
