Abstract

Clamping device comprises clamping points (11, 12, 13) arranged on a base plate (10) with rails (14, 15, 16) rotating across the sliding direction of the clamping points and/or about an axis perpendicular to the plane of the base plate. Preferred Features: One of the clamping points can be adjusted in height with respect to the base plate. The clamping points are computer-controlled.

Description

Die Erfindung betrifft eine Spannvorrichtung mit zwei oder mehr auf einer Grundplatte angeordneten Spannstellen, von denen wenigstens eine Spannstelle beweglich auf der Grundplatte angeordnet, nämlich auf einer Schiene in der Ebene der Grundplatte verschieblich geführt ist.The The invention relates to a clamping device with two or more a base plate arranged clamping points, of which at least a clamping point movably arranged on the base plate, namely on a rail is guided displaceably in the plane of the base plate.

Eine solche Spannvorrichtung ist aus der DE 198 61 091 A1 bekannt.Such a tensioning device is from the DE 198 61 091 A1 known.

In der Praxis sind Spannvorrichtungen bekannt, bei denen mehrere Spannstellen, beispielsweise sogenannte Schnellspannzylinder, auf einem Maschinentisch angeordnet sind. In diese Schnellspannzylinder kann eine Wechselpalette, auf der unterschiedliche Werkschlüssel gespannt sein können, gespannt und dann in die Werkstücke, beispielsweise spanend, bearbeitet werden. Zum Teil kommt es auch vor, daß bestimmte Werkstücke direkt in Schnellspannzylindern gespannt werden. In diesem Fall werden Einzugnippel in das Werkstück eingeschraubt und das Werkstück dann mittels dieser Schnellspannzylinder in einer Bearbeitungslinie in unterschiedlichen Werkzeugmaschinen mittels der Schnellspannzylinder gespannt. Auf diese Weise lassen sich die Werkstücke immer positionsgenau spannen und in einer vorgegebenen Bearbeitungsfolge bearbeiten.In In practice clamping devices are known in which several clamping points, For example, so-called quick release cylinder, on a machine table are arranged. In these quick-release cylinders, a removable pallet, on the different tool keys can be curious, looking forward and then into the workpieces, for example, be machined. Partly it comes too before that certain workpieces be clamped directly in quick-release cylinders. In this case Einzugsnippel be screwed into the workpiece and the workpiece then by means of these quick release cylinder in a processing line in different Machine tools clamped by the quick release cylinder. On In this way, the workpieces can always be clamped exactly in position and edit in a predefined sequence.

Zum Teil werden in Bearbeitungslinien in loser Folge unterschiedlich Werkstücke bearbeitet. Dieses erfordert eine variable Anordnung der Spannstellen zu einander. Die Spannstellen müssen deshalb auf dem Maschinentisch versetzt werden. Dieses geschieht beim Stand der Technik dadurch, daß die Spannstellen vom Maschinentisch gelöst, neu ausgerichtet und sodann wieder befestigt werden. Dieses ist sehr arbeitsintensiv und daher mit hohen Umrüstzeiten verbunden. In der DE 198 61 091 A1 ist deshalb vorgeschlagen, eine Spannstelle auf einer Schine beweglich zu führen, während die andere Spannstelle ortsfest ist. Dieses hat den Vorteil, daß die ortsfeste Spannstelle einen Nullpunkt für die Bearbeitung markier, was fertigungstechnische Vorteile hat. Bei hochflexiblen Fertigungen unterschiedlichster Werkstücke ist diese Art der Werkstückspannung aber oft nicht ausreichend flexibel.In part, different workpieces are processed in processing lines in loose sequence. This requires a variable arrangement of the clamping points to each other. The clamping points must therefore be offset on the machine table. This is done in the prior art, characterized in that the clamping points detached from the machine table, realigned and then fixed again. This is very labor intensive and therefore associated with high changeover times. In the DE 198 61 091 A1 It is therefore proposed to move a clamping point on a machine while the other clamping point is stationary. This has the advantage that the stationary clamping point mark a zero point for processing, which has manufacturing advantages. In the case of highly flexible production of a wide variety of workpieces, however, this type of workpiece clamping is often not sufficiently flexible.

Hiervon ausgehend liegt der Erfindung das Problem zugrunde, eine Spannvorrichtung der eingangs genannten Art derart weiterzubilden, daß unterschiedliche Werkstücke in loser Folge hochflexible spannbar sind.Of these, the invention is based on the problem, a clamping device of the type mentioned in such a way that different workpieces can be tensioned very flexibly in loose sequence.

Zur Lösung dieses Problems ist die erfindungsgemäße Spannvorrichtung dadurch gekennzeichnet, daß die Schiene quer zur Verschieberichtung der Spannstelle verschieblich und/oder um eine Achse senkrecht zur Ebene in der Grundplatte rotierbar istto solution This problem is the clamping device according to the invention thereby characterized in that Rail displaceable transversely to the displacement direction of the clamping point and / or rotatable about an axis perpendicular to the plane in the base plate is

Gegenüber der Spannvorrichtung nach der DE 198 61 091 A1 ist die bewegliche Spannstelle also zweidimensional auf der Grundplatte beweglich. Die Spannstelle läßt sich nicht nur in Längsrichtung der Schiene verschieben, sondern auch innerhalb des Bewegungsraums der Schiene in der Ebene der Grundplatte zweidimensional verfahren. Auf diese Weise ist die Spannvorrichtung sehr flexibel für unterschiedlichste Werkstücke verwendbar. Gegebenenfalls kann die Spannstelle auch in ihrer Höhe (Abstand zur Grundplatte) beweglich sein, so daß sich eine dreidimensionale Einstellungsmöglichkeit ergibt.Opposite the clamping device after the DE 198 61 091 A1 is the movable clamping point so two-dimensionally movable on the base plate. The clamping point can not only be displaced in the longitudinal direction of the rail, but also moved two-dimensionally within the movement space of the rail in the plane of the base plate. In this way, the clamping device is very flexible for a variety of workpieces used. Optionally, the clamping point in its height (distance from the base plate) to be movable, so that there is a three-dimensional adjustment possibility.

Noch flexibler wird die Spannvorrichtung, wenn jede Spannstelle beweglich ist.Yet The tensioning device becomes more flexible when each tensioning point is movable is.

Die Bewegung der Spannstellen bzw. der Spannstellen ist vorzugsweise computergesteuert. Dabei sollte dem Werkstück eine computeridentifizierbare Kennung, beispielsweise in Form eines Barcodes zugeordnet sein, die von der Werkzeugmaschine eingelesen und an eine Steuereinheit weitergemeldet wird, die dann die Orientierung der Spannstellen zueinander automatisch für die positionsgenaue Spannung des Werkstücks einstellt.The Movement of the clamping points or the clamping points is preferably computer controlled. The workpiece should be computer-identifiable Identifier, for example in the form of a barcode, read from the machine tool and to a control unit then the orientation of the clamping points each other automatically for sets the positionally accurate tension of the workpiece.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:The Invention will now be described with reference to a drawing embodiment explained in more detail. It demonstrate:
