Description
Die Erfindung betrifft eine Vorrichtung zum automatischen Werkzeug- oder Werkstückträgerwechsel nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device for automatic tool or workpiece carrier change according to the preamble of claim 1.
Aus
der
Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art zu schaffen, bei der ein unbeabsichtigtes Lösen der Werkzeugaufnahmen, Werkzeuge oder Werkstückträger an der Werkzeug- oder Werkstückträger-Wechseleinrichtung auf einfache und dennoch sichere Weise vermieden werden kann.task The invention is a device of the type mentioned in which an unintentional release of the tool holders, Tools or workpiece carriers on the tool or workpiece carrier changing device to simple and yet safe way can be avoided.
Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Weiterbildungen und vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.These The object is achieved by a device having the features of the claim 1 solved. Appropriate further education and advantageous embodiments of the invention are the subject the dependent claims.
Bei der erfindungsgemäßen Vorrichtung umfasst die Arretiereinrichtung eine dem jeweiligen Greifer zugeordnete Steuerstange und eine mit dieser zusammenwirkende Steuerrolle an dem zwischen einer Klemmstellung und einer Wechselstellung beweglichen Greiferelement, wobei die Steuerstange eine als Anschlagfläche für die Steuerrolle dienende Sperrfläche zur Arretierung des zweiten Greiferelements in der Klemmstellung und eine Vertiefung zum Eingriff der Steuerrolle für die Bewegung des zweiten Greiferelements in die Wechselstellung enthält. Durch die Kombination von Steuerstange und Steuerrolle wird bei der erfindungsgemäßen Vorrichtung eine äußerst verschleißarme und dennoch sichere Verriegelung erreicht. Über die Steuerstange kann mit Ausnahme der durch Vertiefung vorgegebenen Wechselposition eine starre Blockierung des zweiten Greiferelements in der Klemmstellung erreicht werden, so dass während der Axialbewegung und des Schwenkvorgangs der Werkzeug- oder Werkstückträger-Wechseleinrichtung keine Bewegung des zweiten Greiferelements in die Wechselstellung erfolgen kann und damit eine sichere Halterung der Werkzeuge oder Werkstückträger gewährleistet ist. Die einzelnen Komponenten der Arretiereinrichtung sind geringeren mechanischen Belastungen ausgesetzt, so dass die Wartungsintervalle reduziert und durch Reparatur bedingte Betriebssausfälle verringert werden können. Darüber hinaus wird durch den über die Schaltstange und die Schaltrolle vorgegebenen Bewegungsverlauf des beweglichen zweiten Greiferelements erreicht, dass das im Werkzeuggreifer gehaltene Werkzeug bereits beim Beginn der Linearbewegung der Werkzeugwechseleinrichtung, d. h. beim Herausziehen der Werkzeugaufnahmen oder Werkzeuge aus der Arbeitspindel, und auch während der Schwenkbewegung der Werkzeugwechseleinrichtung sicher arretiert bzw. verriegelt ist.at the device according to the invention comprises Locking device associated with the respective gripper control rod and a cooperating with the control role at the between a clamping position and a change position movable gripper element, the control rod as a stop surface for the control role serving blocking surface for locking the second gripper element in the clamping position and a recess for engaging the control roller for the movement of the second Gripper element contains in the change position. By the Combination of control rod and control roller is in the inventive Device a very low-wear and yet achieved secure locking. About the control rod can with the exception of the specified by deepening change position one rigid blocking of the second gripper element in the clamping position be achieved so that during the axial movement and the pivoting operation of the tool or workpiece carrier changing device no movement of the second gripper element in the change position can be done and thus secure mounting of the tools or Workpiece carrier is guaranteed. The individual components of the locking device are lower mechanical Exposed loads, so that reduces the maintenance intervals and reduced due to repair operational failures can be. In addition, through the over the shift rod and the switching role predetermined course of movement the movable second gripper element reaches that in the tool gripper held tool already at the beginning of the linear movement of the tool changing device, d. H. when pulling out the tool holders or tools from the Work spindle, and also during the pivoting movement of Tool changing device is securely locked or locked.
Die dem jeweiligen Werkzeuggreifer zugeordnete Steuerstange verläuft zweckmäßigerweise parallel zur Längsachse durch eine entsprechende Durchgangsöffnung des Tragkörpers.The the control rod associated with the respective tool gripper runs expediently parallel to the longitudinal axis through a corresponding passage opening of the support body.
Dadurch ist eine kompakte Bauweise erreichbar. In einer fertigungstechnisch vorteilhaften Ausführung ist die Steuerstange als Welle mit einem kreisrunden Querschnitt ausgeführt.Thereby is a compact design accessible. In a production engineering advantageous embodiment, the control rod is a shaft executed with a circular cross-section.
Da die Steuerstangen bei der Drehung der Werkzeugwechseleinrichtung um die Längsachse mit verschwenkt werden müssen, sind sie in einer zweckmäßigen Ausführung an einem drehbar gelagerten Ring befestigt.There the control rods during rotation of the tool changing device must be pivoted with the longitudinal axis, are they in an expedient execution attached to a rotatably mounted ring.
Das erste Greiferelement ist zweckmäßigerweise als festes Greiferelement ausgeführt, kann aber auch beweglich sein. Das zwischen einer Klemmstellung und Wechselstellung bewegliche zweite Greiferelement kann z. B. als Schieber mit einem vorderen Endstück zum Eingriff in eine Ringnut der Werkzeugaufnahme ausgebildet sein. Das zweite Greiferelement kann aber auch ein schwenkbarer Greiferarm oder dgl. sein.The first gripper element is expediently designed as a fixed gripper element, but may also be movable. The movable between a clamping position and change position second gripper element can, for. B. may be formed as a slide with a front end piece for engagement in an annular groove of the tool holder. But the second gripper element can also be a swivel Gripper arm or the like. Be.
In einer bevorzugten Ausführung ist die Werkzeug- oder Werkstückträger-Wechseleinrichtung als Doppelgreifer mit zwei diametral gegenüberliegenden Greifern ausgeführt. Die Werkzeug- oder Werkstückträger-Wechseleinrichtung kann aber auch nur einen oder mehr als zwei Greifer aufweisen.In A preferred embodiment is the tool or workpiece carrier changing device as a double gripper with two diametrically opposed Grippers executed. The tool or workpiece carrier changing device but may also have only one or more than two grippers.
Das gegenüber dem Tragkörper nach vorne vorstehende Ende der Steuerstange, an dem sich auch die Vertiefung für den Eingriff der Steuerrolle befindet, wird zum Schutz gegen Verschmutzung zweckmäßigerweise durch eine Abdeckung abgedeckt.The protruding forward of the support body End of the control rod, which is also the recess for the intervention of the control roller is expediently to protect against contamination covered by a cover.
Weitere Besonderheiten und Vorzüge der Erfindung ergeben sich aus der folgenden Beschreibung eines bevorzugten Ausführungsbeispiels anhand der Zeichnung.

Die Erfindung ist nicht auf die vorstehend beschriebenen Ausführungsbeispiele beschränkt. Anstelle eines Doppelgreifers mit zwei gegenüberliegenden Greifern können auch nur einer oder mehr als zwei Greifer mit der entsprechenden Anzahl an Steuerstangen und Steuerrollen vorgesehen sein. Bei geeigneter Ausgestaltung der Greifer kann die Vorrichtung außerdem für einen Werkstückträgerwechsel eingesetzt werden.The invention is not limited to the embodiments described above. At In the case of a double gripper with two opposing grippers, only one or more than two grippers with the corresponding number of control rods and control rollers can be provided. In a suitable embodiment of the gripper, the device can also be used for a workpiece carrier change.
