Description

Die Erfindung betrifft eine Spannvorrichtung gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a clamping device according to the preamble of patent claim 1.

Solch eine Spannvorrichtung ist beispielsweise aus der EP-A-1 398 115 bekannt.Such a tensioning device is for example from the EP-A-1 398 115 known.

Eine insbesondere im Fahrzeugbau eingesetzte Spannvorrichtung der eingangs genannten Art ist nach der DE 196 52 468 C1 bekannt. Diese besteht aus einem wahlweise pneumatischen, hydraulischen oder elektrischen Antriebselement, einem am Antriebselement angeordneten Gehäuse, einer im Gehäuse angeordneten, mit dem Antriebselement wirkverbundenen Stellmechanik, einer ersten drehbar im Gehäuse gelagerten, mit der Stellmechanik wirkverbundenen Schwenkachse für ein Spannwerkzeug (Spannarm), einer zweiten drehbar im Gehäuse gelagerten, mit der Stellmechanik wirkverbundenen Schwenkachse und einem von ausserhalb des Gehäuses zugänglichen, fest aber lösbar an der zweiten Schwenkachse angeordneten Handbetätigungshebel für das Spannwerkzeug.An especially used in vehicle clamping device of the type mentioned is according to the DE 196 52 468 C1 known. This consists of an optionally pneumatic, hydraulic or electric drive element, a housing arranged on the drive element, arranged in the housing, operatively connected to the drive element actuating mechanism, a first rotatably mounted in the housing, operatively connected to the actuating mechanism pivot axis for a clamping tool (clamping arm), a second rotatably mounted in the housing, operatively connected to the actuating mechanism pivot axis and accessible from outside the housing, but firmly arranged on the second pivot axis manually operated lever for the clamping tool.

Bei computergesteuertem Betrieb wird mittels des Antriebselements die Stellmechanik und mittels dieser das Spannwerkzeug betätigt. In bestimmten Situationen oder Produktionsprozessen ist aber auch eine Betätigung der Spannvorrichtung von Hand erforderlich. Zu diesem Zweck ist, wie erwähnt, an der Spannvorrichtung eine zweite, mit der Stellmechanik wirkverbundene Schwenkachse vorgesehen, an der ein von aussen gut zugänglicher Handbetätigungshebel angeordnet ist (siehe hierzu insbesondere Spalte 5, Zeilen 6 bis 13 der genannten DE 196 52 468 C1 ).In computer-controlled operation, the actuating mechanism is actuated by means of the drive element and by means of this the clamping tool. In certain situations or production processes but also an operation of the clamping device by hand is required. For this purpose, as mentioned, a second, operatively connected to the adjusting mechanism pivot axis is provided on the clamping device on which a readily accessible from the outside hand lever is arranged (see in particular column 5, lines 6 to 13 of the above DE 196 52 468 C1 ).

Bei der Spannvorrichtung gemäß der DE 196 52 468 C1 ist die zweite Schwenkachse fester Bestandteil der Gesamtvorrichtung, d. h. der Käufer einer solchen Vorrichtung hat sich beim Kauf zu entscheiden, ob er eine solche, spezielle Spannvorrichtung mit Handhebel oder eine nichthandbetätigbare Lösung erwerben möchte. Eine nachträgliche Umrüstung ist nicht vorgesehen.In the tensioning device according to the DE 196 52 468 C1 the second pivot axis is an integral part of the overall device, ie the buyer of such a device has to decide when buying whether he wants to acquire such a special clamping device with hand lever or a non-hand-operated solution. A subsequent conversion is not provided.

Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu beseitigen, d. h. eine Spannvorrichtung der eingangs genannten Art dahingehend weiterzubilden, dass diese zu jedem beliebigen Zeitpunkt wahlweise mit oder ohne Handhebel einsetzbar ist bzw. auch nachträglich mit einem Handbetätigungshebel versehen werden kann.The invention has for its object to overcome this disadvantage, d. H. a further develop a clamping device of the type mentioned in that it can be used at any time either with or without hand lever or can be retrofitted with a manual operating lever.

Diese Aufgabe ist mit einer Spannvorrichtung der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst.This object is achieved with a clamping device of the type mentioned by the features listed in the characterizing part of patent claim 1.

Nach der Erfindung ist also vorgesehen, dass am Gehäuse im Bereich der zweiten Schwenkachse ein mit einem lösbaren Gehäusedeckel verschließbarer Öffnungsbereich vorgesehen und mindestens die zweite Schwenkachse bei geöffnetem Gehäusedeckel aus dem Gehäuse demontierbar ausgebildet ist. Mit anderen Worten ausgedrückt, besteht die eigentliche Handhebelmechanik erfindungsgemäß nunmehr aus einem vorgefertigten Modul, welches nachträglich in den Spanner einseLz- und dort fixierbar ist. Diese modulare Gestaltung erlaubt eine weit größere Flexibilität in der Reaktion auf kurze Liefertermine bzw. reduziert die Lagerhaltung speziell ausgebildeter Spannvorrichtungen mit und ohne Handhebelmechanik.According to the invention, it is therefore provided that the housing in the region of the second pivot axis provided with a detachable housing cover closable opening area and at least the second pivot axis is formed removable with the housing cover open from the housing. In other words, the actual hand lever mechanism according to the invention now consists of a prefabricated module, which is subsequently inserted into the tensioner and fixable there. This modular design allows a much greater flexibility in the response to short delivery dates or reduces the storage of specially designed clamping devices with and without hand lever mechanism.

Andere vorteilhafte Weiterbildungen ergeben sich aus den abhängigen Patentansprüchen.Other advantageous developments emerge from the dependent claims.

Die erfindungsgemäße Spannvorrichtung einschließlich ihrer vorteilhaften Weiterbildungen wird nachfolgend anhand der zeichnerischen Darstellung eines bevorzugten Ausführungsbeispiels näher erläutert.The clamping device according to the invention including its advantageous developments is explained in more detail below with reference to the drawing of a preferred embodiment.

In den Figuren 1 bis 7 ist eine bevorzugte Ausführungsform der erfindungsgemäßen Spannvorrichtung dargestellt. Diese umfasst ein Antriebselement 1, das in an sich bekannter Weise und je nach Bedarf als pneumatischer, hydraulischer oder elektrischer Antrieb ausgebildet sein kann.FIGS. 1 to 7 show a preferred embodiment of the tensioning device according to the invention. This comprises a drive element 1, which can be designed in a conventional manner and as needed as a pneumatic, hydraulic or electric drive.

Am Antriebselement 1 ist in ebenfalls an sich bekannter Weise ein Gehäuse 2 angeordnet, das aus zwei, jedenfalls teilweise spiegelsymmetrischen Schalen 20, 21 gebildet ist. Die Maßgabe "jedenfalls teilweise spiegelsymmetrisch" bringt dabei zum Ausdruck, dass die beiden Gehäuseschalen im wesentlichen gleich sind, selbstverständlich aber auch kleine Abweichungen von einander aufweisen können. Zu einer solchen Abweichung gehört beispielsweise der noch genauer zu erläuternde, erfindungsgemäße Öffnungsbereich 9.On the drive element 1, a housing 2 is arranged in a manner also known per se, which is formed of two, at least partially mirror-symmetrical shells 20, 21. The proviso "at least partially mirror-symmetrical" expresses the fact that the two housing shells are substantially equal, but of course also may have small deviations from each other. Such a deviation includes, for example, the opening region 9 according to the invention, which will be explained in more detail below.

Im Gehäuse 2 ist eine mit dem Antriebselement 1 wirkverbundene Stellmechanik 3 vorgesehen. Ferner umfasst die Spannvorrichtung eine erste drehbar im Gehäuse 2 gelagerte, mit der Stellmechanik 3 wirkverbundene Schwenkachse 4 für ein Spannwerkzeug 5. Darüber hinaus ist eine zweite drehbar,im Gehäuse 2 gelagerte, mit der Stellmechanik 3 wirkverbundene Schwenkachse 6 sowie ein von außerhalb des Gehäuses 2 zugänglicher, fest aber lösbar an der zweiten Schwenkachse 6 angeordneter Handbetätigungshebel 7 für das Spannwerkzeug 5 vorgesehen, um die Spannvorrichtung im Bedarfsfall auch per Hand öffnen und schließen zu können.In the housing 2 an operatively connected to the drive element 1 actuating mechanism 3 is provided. Furthermore, the clamping device comprises a first rotatably mounted in the housing 2, operatively connected to the actuating mechanism 3 pivot axis 4 for a clamping tool 5. In addition, a second rotatable, mounted in the housing 2, operatively connected to the actuating mechanism 3 pivot axis 6 and from outside the housing second accessible, but releasably arranged on the second pivot axis 6 hand lever 7 provided for the clamping tool 5 to open the clamping device in case of need by hand and close.

Wesentlich für die erfindungsgemäße Spannvorrichtung ist nun (siehe hierzu insbesondere Figur 2), dass am Gehäuse 2 im Bereich der zweiten Schwenkachse 6 ein mit einem lösbaren Gehäusedeckel 8 verschließbarer öffnungsbereich 9 vorgesehen und mindestens die zweite Schwenkachse 6 bei geöffnetem Gehäusedeckel 8 aus dem Gehäuse 2 demontierbar ausgebildet ist.It is essential for the tensioning device according to the invention (see in particular FIG. 2) that on the housing 2 in the region of the second pivot axis 6 an opening area 9 closable with a detachable housing cover 8 be provided and at least the second pivot axis 6 can be removed from the housing 2 when the housing cover 8 is open is trained.

Diese Maßgabe ermöglicht, dass der gesamte Handbetätigungsmechanismus im Bedarfsfall nachrüstbar ist bzw., falls er nicht mehr benötigt wird, demontiert werden kann.This requirement makes it possible that the entire manual operation mechanism can be retrofitted if necessary or, if it is no longer needed, can be dismantled.

Wie aus Figur 2 ersichtlich, ist vorteilhaft vorgesehen, dass der Gehäusedeckel 8 für die zweite Schwenkachse 6 eine Öffnung 10 aufweist, die bei demontierter zweiter Schwenkachse 6 (siehe Figur 3) mit einem Deckelelement 11 verschließbar ausgebildet ist.As can be seen from FIG. 2, it is advantageously provided that the housing cover 8 for the second pivot axis 6 has an opening 10 which, with a disassembled second pivot axis 6 (see FIG. 3), is designed to be closable with a cover element 11.

Um die Montage des Handbetätigungsmechanismus möglichst einfach zu gestalten, ist ferner vorteilhaft vorgesehen, dass die zweite Schwenkachse 6 in einem Trägerelement 12 drehbar gelagert ist, das zu einer inneren Kontur des Gehäuses 2 formangepaßt und zusammen mit der zweiten Schwenkachse 6 demontierbar ausgebildet ist. Dieses Trägerelement 12 ist somit bei geöffnetem Gehäusedeckel 8 leicht ein- und ausbaubar und stützt sich, und damit die Schwenkachse 6, an einer inneren wandung im Gehäuse 2 ab, so dass die Schwenkachse 6 gut fixiert im Gehäuse 2 positioniert ist.In order to make the assembly of the manual actuation mechanism as simple as possible, it is further advantageous that the second pivot axis 6 is rotatably mounted in a support member 12 which is adapted to an inner contour of the housing 2 and formed together with the second pivot axis 6 removable. This support member 12 is thus easy to install and remove with the housing cover 8 and is supported, and thus the pivot axis 6, on an inner wall in the housing 2, so that the pivot axis 6 is well fixed in the housing 2 is positioned.

Alternativ zum Trägerelement 12 ist vorgesehen, dass das Gehäuse 2 passende Bohrungen mit Lagerbuchsen für die Schwenkachse 6 aufweist (nicht dargestellt, da ohne weiteres vorstellbar). Die Schwenkachse 6 wird in diese Lagerstelle eingeschoben. Die axiale Fixierung erfolgt zum einen durch den Gehäusedeckel 8 und zum anderen durch eine Fläche im Gehäuse 2, in dem das Stellglied 16 zwischen den genannten Bauteilen geführt wird und dadurch nach beiden Richtungen axial gesichert ist.As an alternative to the carrier element 12, it is provided that the housing 2 has matching bores with bearing bushes for the pivot axis 6 (not shown, since it is readily conceivable). The pivot axis 6 is inserted into this bearing. The axial fixing takes place on the one hand through the housing cover 8 and on the other hand by a surface in the housing 2, in which the actuator 16 is guided between said components and thereby axially secured in both directions.

Die bereits erwähnte Stellmechanik 3, die eine mit dem Antriebselement 1 verbundene, linear bewegliche und orthogonal zu den beiden Schwenkachsen 4, 6 orientierte Stellstange 13 aufweist, ist in den Figuren 1 bis 7 als sogenannte Kniehebelmechanik ausgebildet.The already mentioned adjusting mechanism 3, which has a connected to the drive element 1, linearly movable and orthogonal to the two pivot axes 4, 6 oriented control rod 13 is formed in the figures 1 to 7 as a so-called toggle mechanism.

Genauso gut kann aber auch (nicht dargestellt) eine sogenannte Kurvenmechanik (siehe hierzu zum Beispiel die DE 102004007465 A1 ) eingesetzt werden. In diesem Fall ist am antriebselementfernen Ende der Stellstange 13 ein mit einer Kurvenführung zusammenwirkendes Eingriffselement angeordnet, wobei die Kurvenführung an einer Angriffslasche vorgesehen und diese verdrehfest an der ersten Schwenkachse befestigt ist.But just as well can also (not shown) a so-called curve mechanics (see, for example, the DE 102004007465 A1 ) are used. In this case, an actuating element cooperating with a cam guide is arranged at the drive element remote end of the adjusting rod 13, wherein the cam guide is provided on an engaging tab and this is secured against rotation on the first pivot axis.

Sollte die Stellmechanik, wie in den Figuren 1 bis 7 dargestellt, als Kniehebelmechanik ausgebildet sein, so ist in ebenfalls bekannter Weise am antriebselementfernen Ende der Stellstange 13 drehbar gelagert ein zwischenglied 14 angelenkt, das seinerseits mit einer an der ersten Schwenkachse 4 vorgesehenen Angriffslasche 15 wirkverbunden ist.If the adjusting mechanism, as shown in Figures 1 to 7, be designed as a toggle mechanism, then in a known manner at the drive element remote end of the control rod 13 rotatably mounted an intermediate member 14 hinged, which in turn operatively connected to a provided on the first pivot axis 4 attack tab 15 is.

Um den Handbetätigungsmechanismus mit der Stellmechanik 3 zu verbinden, ist vorgesehen, dass die zweite Schwenkachse 6 mit dem antriebselementfernen Ende der Stellstange 13 wirkverbunden ist. Dazu ist (siehe insbesondere Figur 4, 5 und 7) an der zweiten Schwenkachse 6 ein erstes, verdrehfest mit dieser verbundenes Stellglied 16 angeordnet, das über ein Drehgelenk 17 mit einem zweiten Stellglied 18 wirkverbunden ist, welches seinerseits drehbar am antriebselementfernen Ende der Stellstange 13 angeordnet ist.In order to connect the manual operation mechanism with the adjusting mechanism 3, it is provided that the second pivot axis 6 is operatively connected to the drive element remote end of the control rod 13. For this purpose (see in particular Figures 4, 5 and 7) at the second pivot axis 6, a first rotationally fixedly connected thereto actuator 16 is arranged, which is operatively connected via a rotary joint 17 with a second actuator 18, which in turn rotatably on the drive element remote end of the control rod thirteenth is arranged.

Damit das zweite Stellglied 18 bei demontierter zweiter Schwenkachse 6 nicht lose im Gehäuse 2 umherpendeln kann, ist dieses verdrehfest mit der Stellstange 13 bzw. mit deren Kopf verbindbar ausgebildet. Im Detail ist vorgesehen (siehe insbesondere Figur 5 und 6), dass zur Verdrehsicherung zwischen dem zweiten Stellglied 18 umd dem antriebselementfernen Ende der Stellstange 13 eine Schraubenverbindung 19 angeordnet ist. Diese Schraubenverbindung 19 ist, wie aus Figur 2 ersichtlich, bei geöffnetem Gehäusedeckel 8 und bei Öffnungsposition der Spannvorrichtung über den Öffnungsbereich 9 gut zugänglich und kann auf diese Weise leicht betätigt werden.Thus, the second actuator 18 with disassembled second pivot axis 6 can not loosely circulate in the housing 2, this is rotationally fixed to the control rod 13 and with their head connectable trained. It is provided in detail (see in particular FIGS. 5 and 6) that a screw connection 19 is arranged between the second actuator 18 around the drive-element-remote end of the control rod 13 in order to prevent rotation. As can be seen in FIG. 2, this screw connection 19 is easily accessible via the opening region 9 when the housing cover 8 is open and at the opening position of the clamping device, and can be easily actuated in this way.

Schließlich ist, wie aus Figur 2 ersichtlich, vorteilhaft vorgesehen, dass die zweite Schwenkachse 6, das erste Stellglied 16 und das Trägerelement 12 gemeinsam als ein Modul demontierbar ausgebildet sind.Finally, as can be seen from FIG. 2, it is advantageously provided that the second pivot axis 6, the first actuator 16 and the carrier element 12 are designed to be removable as a module.
