Description

Die Erfindung bezieht sich auf einen Unterdrucksauger zum bearbeitungsgerechten Abstützen und Festspannen von Werkstücken, mit einem höhenverstellbaren Hubstempel, der einen Kopfteil zur gelenkigen Aufnahme eines unterdruckbeaufschlagbaren Saugnapfes trägt.The invention relates to a vacuum cleaner for machining-appropriate support and clamping of workpieces, with a height-adjustable lifting ram, which carries a head part for the articulated reception of a suction cup that can be pressurized.

Zum Spannen von räumlich vorgeformten dünnwandigen Werkstücken oder Werkstücken mit gekrümmter Oberfläche u. dgl. haben sich bereits Arbeitstische, die einstellbare Unterdrucksauger aufweisen, bewährt, da diese Unterdrucksauger mit Hilfe ihrer höhenverstellbaren, gelenkig abgestützten Saugnäpfe an die jeweiligen Werkstücke angepaßt und dadurch auch Werkstücke komplizierter und heikler Form mit für eine durchzuführende Bearbeitung ausreichender Festigkeit und Stabilität halten können. Die der Höhe nach entsprechend positionierten Saugnäpfe lassen sich gegenüber den sie tragenden Hubstempeln verschwenken, so daß sie auch der jeweils vorhandenen Neigung der Werkstückoberfläche folgen und eine satte Abstützung sicherstellen können. Allerdings sind bisher die Saugnäpfe, wie beispielsweise die EP-B1-0 069 230 zeigt, kugelgelenkartig gelagert, wobei die einzelnen Näpfe mit ihrer kugelflächigen Außenseite in einer Halbkugelschale des Hubstempel-Kopfteiles sitzen, was zwar eine allseitige Schwenkbeweglichkeit, aber nur einen sehr geringen Schwenkbereich mit sich bringt und damit die Anpassungsmöglichkeit begrenzt. Dazu kommt noch, daß reibungsbedingt die gewünschte Leichtgängigkeit der Schwenkbewegung für den Ansatz der Saugnäpfe an sehr dünnwandige und biegeweiche Werkstücke oft unzureichend ist und beim Anlegen zu örtlichen Verformungen des Werkstückes führt. Außerdem setzt das angestrebte Schwenkverhalten der Saugnäpfe eine hohe Präzision der Kugelflächen des Kugelgelenks voraus, wodurch ein entsprechender Herstellungsaufwand unvermeidbar ist.For clamping spatially preformed thin-walled workpieces or workpieces with a curved surface u. The like. Work tables which have adjustable vacuum cups have already proven themselves, since these vacuum cups can be adapted to the respective workpieces with the aid of their height-adjustable, articulated-supported suction cups and can therefore also hold workpieces of complicated and delicate shape with sufficient strength and stability for machining to be carried out. The suction cups, which are positioned correspondingly in height, can be pivoted relative to the lifting rams carrying them, so that they can also follow the inclination of the workpiece surface in each case and ensure a solid support. However, so far, the suction cups, as shown, for example, by EP-B1-0 069 230, have a ball-and-socket joint, the individual bowls with their spherical outer surface being seated in a hemispherical shell of the lifting-stamp head part, which, although it can be swiveled on all sides, but only has a very small swivel range brings with it and thus limits the possibility of customization. In addition, due to friction, the desired smooth movement of the pivoting movement for the attachment of the suction cups to very thin-walled and flexible workpieces is often inadequate and leads to local deformations of the workpiece when applied. In addition, the desired swiveling behavior of the suction cups requires a high precision of the spherical surfaces of the ball joint, which means that a corresponding manufacturing outlay is inevitable.

Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel zu beseitigen und einen Unterdrucksauger der eingangs geschilderten Art zu schaffen, der verhältnismäßig einfach gefertigt werden kann und sich durch seine Beweglichkeit und seinen großen Schwenkbereich auszeichnet.The invention is therefore based on the object to eliminate these deficiencies and to provide a vacuum cleaner of the type described which can be manufactured relatively easily and is distinguished by its mobility and its large swivel range.

Die Erfindung löst diese Aufgabe dadurch, daß der Saugnapf stempelseitig einen Ansatzteil aufweist, der mit dem Kopfteil des Hubstempels über ein Kreuzgelenk verbunden ist. Das Kreuzgelenk bietet dem Saugnapf eine feste, stabile Abstützung und ermöglicht eine reibungsarme, allseitige Verschwenkbarkeit des Saugnapfes mit genügend großem Schwenkwinkel. Das Kreuzgelenk läßt sich außerdem mit hoher Genauigkeit auf rationelle Weise herstellen und es entsteht ein Unterdrucksauger mit leichtgängig bewegbarem, in seiner Höhen-und Schräglage bestens an die jeweiligen Werkstückformen und -positionen anpaßbarem Saugnapf.The invention solves this problem in that the suction cup on the punch side has an attachment part which is connected to the head part of the lifting punch via a universal joint. The universal joint provides the suction cup with firm, stable support and enables low-friction, all-round pivoting of the suction cup with a sufficiently large swivel angle. The universal joint can also be produced with a high degree of accuracy in a rational manner, and a vacuum suction cup is created with a smoothly movable suction cup, the height and inclination of which can be optimally adapted to the respective workpiece shapes and positions.

Besonders vorteilhaft ist es, wenn das Kreuzgelenk von einer elastisch-flexiblen, sowohl am Kopfteil als auch am Ansatzteil dicht angeschlossenen Manschette umhüllt ist und in den Manschetteninnenraum einerseits eine durch den Hubstempel führende Luftleitung und anderseits eine Durchlaßbohrung des Saugnapfes münden. Eine solche Manschette, die beispielsweise als einfacher, schraubenfederbestückter Schlauch od. dgl. ausgebildet sein kann, ergibt sich eine funktionssichere Leitungsverbindung von einer Unterdruck- oder Druckluftquelle zum Saugnapf, da über die Durchlaßbohrung, den Manschetteninnenraum und die Luftleitung im Hubstempel auch der Saugnapf selbst je nach Anschluß der Luftleitung an eine Unterdruck- oder Druckluftquelle über diese Quellen unter- oder überdruckbeaufschlagt werden kann. Darüber hinaus kommt es durch die Elastizität der Manschette zu einer ausreichenden Rückstellkraft für den Saugnapf, die praktisch ohne Beeinträchtigung der Schwenkbeweglichkeit den unbelasteten Saugnapf stets in eine mittige Ausgangsstellung zurückbringt und eine für eine neue Anpaßbewegung des Saugnapfes an ein Wekstück ungünstige Ausgangsschwenklage verhindert.It is particularly advantageous if the universal joint is encased by an elastically flexible sleeve which is tightly connected both to the head part and to the attachment part and, on the one hand, an air line leading through the lifting ram and on the other hand a passage bore of the suction cup open into the inside of the sleeve. Such a cuff, which can be designed, for example, as a simple, helical spring-loaded hose or the like, results in a functionally reliable line connection from a vacuum or compressed air source to the suction cup, since the suction cup itself also depends on the passage bore, the cuff interior and the air line in the lifting ram after connecting the air line to a vacuum or compressed air source, these sources can be subjected to negative or positive pressure. In addition, due to the elasticity of the cuff, there is a sufficient restoring force for the suction cup, which practically always returns the unloaded suction cup to a central starting position practically without impairing the pivoting mobility and prevents an initial pivoting position which is unfavorable for a new adaptation movement of the suction cup to a workpiece.

In der Zeichnung ist ein erfindungsgemäßer Unterdrucksauger beispielsweise in einem Axialschnitt näher veranschaulicht.In the drawing, a vacuum cleaner according to the invention is illustrated in more detail, for example, in an axial section.

Ein Unterdrucksauger 1 eines nicht weiter dargestellten Arbeitstisches weist einen höhenvestellbar geführten Hubstempel 2 auf, der einen Kopfteil 3 zur Aufnahme eines unterdruckbeaufschlagbaren Saugnapfes 4 trägt. Der Kopfteil 3 ist mit einem Ansatzteil 5 des Saugnapfes 4 über ein Kreuzgelenk 6 verbunden, wobei eine sowohl am Ansatzteil 5 als auch am Kopfteil 3 dicht angesetzte elastischflexible Manschette 7 das Kreuzgelenk 6 umhüllt. Eine Luftleitung 8 des Hubstempels 2 mündet durch einen Luftkanal 9 des Kopfteiles 3 in den Manschetteninnenraum 10 und der Saugnapf 4 ist über eine Durchlaßbohrung 11 ebenfalls mit dem Manschetteninnenraum 10 leitungsverbunden, so daß über die Luftleitung 8 des Hubstempels 2 der Saugnapf 4 bedarfsweise mit Unterdruck oder Druckluft beaufschlagt werden kann.A vacuum cleaner 1 of a work table (not shown further) has a height-adjustable lifting plunger 2 which carries a head part 3 for receiving a suction cup 4 which can be pressurized. The head part 3 is connected to a shoulder part 5 of the suction cup 4 via a universal joint 6, an elastically flexible sleeve 7, which is tightly attached to both the shoulder part 5 and the head part 3, enveloping the universal joint 6. An air line 8 of the lifting plunger 2 opens through an air channel 9 of the head part 3 into the cuff interior 10 and the suction cup 4 is also connected via a passage bore 11 to the cuff interior 10, so that via the air line 8 of the lifting plunger 2 the suction cup 4 is under vacuum or if necessary Compressed air can be applied.

Durch die Kreuzgelenkverbindung zwischen Saugnapf 4 und Kopfteil 3 ergibt sich eine leichtgängige Verschwenkbarkeit des Saugnapfes 4 gegenüber dem Hubstempel 2, wobei sich nach allen Seiten hin ein gleichbleibend großer Schwenkbereich von beispielsweise 45 (strichpunktierte Darstellung) ergibt. Es entsteht ein Unterdrucksauger 1, der verhältnismäßig aufwandsarm herstellbar ist und einen sich in seiner Schräglage besonders leichtgängig und in weiten Bereichen an die jeweiligen Gegenbenheiten beim Abstützen eines Werkstückes anpaßbaren Saugnapf aufweist, so daß er zum Spannen heikler, forminstabiler bzw. kompliziert geformter Werkstücke bestens geeignet ist.The universal joint connection between the suction cup 4 and the head part 3 results in a smooth pivoting of the suction cup 4 relative to the lifting plunger 2, with a constant large swiveling range of, for example, 45 (dash-dotted line). The result is a vacuum cleaner 1 which is relatively easy to manufacture and which, in its inclined position, has a suction cup which is adaptable particularly easily and in wide areas to the respective conditions when supporting a workpiece, so that it for clamping delicate, dimensionally unstable or complex shaped workpieces.
