Abstract
Flexible Greiferbacken für ovale oder elliptische Formen, dadurch gekennzeichnet, daß:
1. sich die Kugelköpfe in den Greiferbacken an mehreren Punkten räumlich an die Kontur des eines unrunden Werkstückes anpassen und hierdurch das flexible form- und kraftschlüssiges Einspannen ermöglichen
2. für das Anpassen die Kugelköpfe an das Werkstück eine axiale Verschiebbarkeit durch Druckstücke erfolgt
3. die Winkellage der Kugelköpfe mit einer Arretierschraube und Druckfeder gesichert werden kann
1. The ball heads in the gripper jaws at several points spatially adapt to the contour of a non-circular workpiece and thereby allow the flexible positive and non-positive clamping
2. For adjusting the ball heads to the workpiece an axial displacement by plungers takes place
3. The angular position of the ball heads can be secured with a locking screw and compression spring
Description
Die Erfindung beschreibt eine Vorrichtung, die für das flexible form- und kraftschlüssige Greifen von nicht rotationssymmetrischen Werkstücken mit ovalen oder elliptischen Formen geeignet ist.The invention describes a device which is suitable for the flexible positive and non-positive engagement of non-rotationally symmetrical workpieces with oval or elliptical shapes.
Insbesondere ist die Erfindung für das Einlegen und Entnehmen von geformten Rohren in Pressen mit Robotern anwendbar.In particular, the invention is applicable to the loading and unloading of molded pipes in presses with robots.
Bekannt sind Vorrichtungen mit starren Greiferbacken für das Greifen von unrunden Werkstücken mit Parallelgreifern oder Schwenkgreifern, bei denen die Greiferbacken an die jeweilige Kontur der Werkstücke angepasst sind. Der Nachteil dieser herkömmlichen Lösung besteht im hohen mechanischen Aufwand für die Herstellung der Greiferbacken und das diese jeweils nur für eine spezielle Kontur der Werkstücke geeignet sind.Devices are known with rigid gripper jaws for gripping non-circular workpieces with parallel grippers or swivel grippers, in which the gripper jaws are adapted to the respective contour of the workpieces. The disadvantage of this conventional solution consists in the high mechanical complexity for the production of gripper jaws and that they are only suitable for a particular contour of the workpieces.
Weiterhin sind starre Greiferbacken für rotationssymmetrischen Werkstücke bekannt, die die Werkstücke an mehreren Punkten kontaktieren.Furthermore, rigid gripper jaws for rotationally symmetrical workpieces are known, which contact the workpieces at several points.
Die Erfindung kombiniert diese beiden bekannten technischen Konzepte mithilfe von sich räumlich ausrichtenden, axialverstellbaren Kugelköpfen zu einem neuen mechanischen System.The invention combines these two known technical concepts by means of spatially aligning, axialverstellbaren ball heads to a new mechanical system.

Beschreibung des Funktionsablaufes für das Greifen von Werkstücken:Description of the functional sequence for gripping workpieces:
-
- mit einem Greifer (
1 ) werden die Greiferbacken (2 ) geschlossen- with a gripper (1 ), the gripper jaws (2 ) closed -
- infolge der Andrückkraft legen sich die Kugelköpfe (
3 ) an die Werkstückkontur an- Due to the pressing force, the ball heads (3 ) to the workpiece contour -
- das Werkstückes (
9 ) wird durch die Kugelköpfe kraft- und formschlüssig abgestützt- the workpiece (9 ) is positively and positively supported by the ball heads
Beschreibung des Vorganges für das Anpassen der Backen an eine Kontur:Description of the process for adjusting the jaws to a contour:
-
- durch Drehung des Gewindedruckstückes (
5 ) axiales verschieben der Kugelstückeby rotation of the threaded pressure piece (5 ) axial movement of the ball pieces -
- sichern der Winkellage der Kugelköpfe mit Arretierschraube (
6 ) und Feder (7 )- secure the angular position of the ball heads with locking screw (6 ) and spring (7 ) -
- festsetzen des Gewindedruckstückes (
5 ) mit Kontermutter (8 )- fixing the threaded pressure piece (5 ) with lock nut (8th )
