Description

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

Eine vorallem im Automobilbau eingesetzte Antriebsvorrichtung der eingangs genannten Art ist nach der DE 196 16 441 C1 bekannt. Diese besteht aus einem linear beweglichen Antriebselement, das zur Betätigung eines Spannwerkzeuges über eine in einem Gehäuse angeordnete Stellmechanik mit einer im Gehäuse drehbar gelagerten Schwenkachse wirkverbunden ist. Auf einen druckschriftlichen Nachweis bezüglich derartiger Antriebsvorrichtungen mit mehreren Spannwerkzeugen und mehreren Schwenkachsen wird verzichtet, da diese hinlänglich bekannt sind.An especially used in the automotive drive device of the type mentioned is known from DE 196 16 441 C1. This consists of a linearly movable drive element, which is operatively connected to actuate a clamping tool via a housing arranged in a control mechanism with a rotatably mounted in the housing pivot axis. On a documentary evidence with respect to such drive devices with multiple clamping tools and multiple pivot axes is omitted, since these are well known.

Das Antriebselement ist bei der genannten Antriebsvorrichtung als Pneumatikantrieb ausgebildet. Bekannt sind aber auch solche ansonsten sehr ähnliche Antriebsvorrichtungen mit hydraulischem oder auch elektromotorischem Antrieb. Für die nachfolgend zu diskutierende Erfindung kommen alle möglichen Antriebe sogar Handantriebe in Betracht.The drive element is formed in the said drive device as a pneumatic drive. But are also known otherwise very similar drive devices with hydraulic or electric motor drive. For the invention to be discussed below all possible drives even manual drives come into consideration.

Zur Umsetzung der linearen in eine drehende Bewegung ist bei der genannten Antriebsvorrichtung eine sogenannte Kniehebelmechanik vorgesehen, bei der eine Arretierung des Spannwerkzeugs in Übertotpunktstellung erfolgt. Für die nachfolgend zu diskutierenden Erfindung kommen alle möglichen (also beispielsweise auch entsprechende Kurvenantriebe) Stellmechaniken in Betracht, die geeignet sind, die lineare Bewegung des Antriebselements in eine Drehbewegung der Schwenkachse umzusetzen.To implement the linear into a rotating movement, a so-called toggle mechanism is provided in the said drive device, in which a locking of the clamping tool takes place in the over-center position. For the invention to be discussed below, all possible (ie, for example, also corresponding cam drives) adjusting mechanisms come into consideration, which are suitable for converting the linear movement of the drive element into a rotational movement of the pivot axis.

An der Schwenkachse ist bei der genannten Antriebsvorrichtung ein Spannarm angeordnet, der beispielsweise dazu dient, Karosserieteile zum Schweißen in einer definierten Position zu fixieren. Insbesondere im Karosseriebau werden darüber hinaus u. a. auch noch sogenannte Schubstangen- (auch Stiftzieher genannt), zentrier-, Schwenk- und Unterflurspanner verwendet. Diese Spanner sind regelmäßig als selbständige Elemente mit eigenem Antrieb und eigener Stellmechanik ausgebildet und haben sich insoweit auch bestens bewährt.On the pivot axis, a clamping arm is arranged in the said drive device, which serves, for example, to fix body parts for welding in a defined position. In particular, in the body shop are also, inter alia, still so-called push rod (also called pin puller), Centering, pivoting and underfloor tensioner used. These tensioners are regularly designed as independent elements with their own drive and their own actuating mechanism and have proven themselves in this respect well.

Der Erfindung liegt die Aufgabe zugrunde, eine Antriebsvorrichtung der eingangs genannten Art dahingehend weiter zu bilden, dass auf möglichst einfache Art und Weise und je nach Anwendungsfall die Antriebsvorrichtung nicht nur mit einem Spannarm, sondern auch mit anderen, beispielsweise oben genannten Werkzeugen bestück- und einsetzbar ist.The invention has for its object to further develop a drive device of the type mentioned in that in the simplest possible way and depending on the application, the drive device not only with a clamping arm, but also with other, for example, above tools bestück- and used is.

Diese Aufgabe ist mit einer Antriebsvorrichtung der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst.This object is achieved with a drive 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 ein Zusatzgehäuse fest, aber lösbar angeordnet ist, wobei im zusatzgehäuse eine weitere Stellmechanik vorgesehen ist, die einerseits mit der Schwenkachse und andererseits mit dem am Zusatzgehäuse angeordneten Werkzeug, insbesondere Spannwerkzeug, wirkverbunden ist. Erfindungsgemäß wird somit gewissermaßen eine beispielsweise nach der DE 196 16 441 C1 insoweit bekannte Antriebsvorrichtung um ein Zusatzmodul ergänzt, wobei die an sich bekannte Antriebsvorrichtung als Antrieb für das Zusatzmodul dient und wobei nicht an der Antriebsvorrichtung selbst, sondern am Zusatzmodul das Werkzeug und im Zusatzmodul die für den jeweiligen Anwendungsfall erforderliche Stellmechanik angeordnet ist. Aufgrund des erfindungsgemäßen, anwendungsangepaßt ausgebildeten Zusatzmoduls ist es somit möglich, mit einer einzigen Antriebsvorrichtung den unterschiedlichsten Anforderungen zu genügen.According to the invention it is thus provided that the housing an additional housing is fixed, but releasably disposed, wherein in the additional housing a further adjusting mechanism is provided, which is operatively connected on the one hand with the pivot axis and on the other hand with the arranged on the additional housing tool, in particular clamping tool. According to the invention thus, so to speak, a known example according to DE 196 16 441 C1 so far known drive device is supplemented by an additional module, the known drive device serves as a drive for the additional module and not on the drive device itself, but the additional module and the tool in the additional module is arranged for the particular application required adjusting mechanism. Due to the inventive application-adapted additional module, it is thus possible to meet a wide variety of requirements with a single drive device.

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

Die erfindungsgemäße Antriebsvorrichtung einschließlich ihrer vorteilhaften Weiterbildungen gemäß der abhängigen Patentansprüche wird nachfolgend anhand der zeichnerischen Darstellung verschiedener Ausführungsformen näher erläutert.The drive device according to the invention including its advantageous developments according to the dependent claims will be explained in more detail with reference to the drawing of various embodiments.

Alle in den Figuren 1 bis 10 dargestellten Ausführungsformen der Antriebsvorrichtung umfassen ein Antriebselement 1, das zur Betätigung von (mindestens) einem Werkzeug 5 (vorzugsweise ein Spannwerkzeug) über eine in einem Gehäuse 2 angeordnete, wahlweise als Kniehebel- oder Kurvenmechanik ausgebildete Stellmechanik 3 mit (mindestens) einer im Gehäuse 2 drehbar gelagerten Schwenkachse 4 wirkverbunden ist.All of the embodiments of the drive device illustrated in FIGS. 1 to 10 comprise a drive element 1 which is suitable for actuating (at least) one tool 5 (preferably a clamping tool) via a arranged in a housing 2, optionally designed as a toggle or cam mechanism actuating mechanism 3 with (at least) a rotatably mounted in the housing 2 pivot axis 4 is operatively connected.

Je nach Anwendungsfall, also insbesondere in Abhängigkeit davon, welche Anschlussmöglichkeiten vor Ort bestehen, ist das Antriebselement 1 in an sich bekannter Weise wahlweise als Pneumatik-, Hydraulik- oder Elektroantrieb und/oder auch als Handantrieb ausgebildet. Sollte, wie in Figur 9 dargestellt, ausschließlich ein Handantrieb vorgesehen sein, stellt die Schwenkachse 4 gewissermaßen gleichzeitig in Bauteilunion die Stellmechanik 3 dar.Depending on the application, ie in particular depending on which connection options exist locally, the drive element 1 is formed in a conventional manner either as a pneumatic, hydraulic or electric drive and / or as a manual drive. Should, as shown in Figure 9, only be provided a manual drive, the pivot axis 4 is to some extent at the same time in component union, the actuating mechanism 3.

Insbesondere mit Verweis auf die Figuren 3 und 4 ist die Stellmechanik 3, wie erwähnt, wahlweise als Kniehebel- oder als Kurvenmechanik ausgebildet. Figur 3 zeigt die Kniehebelmechanik, bei der eine mit dem Antriebselement 1 verbundene, linear bewegliche Stellstange 12 über ein Zwischenglied 13 die Drehbewegung der eine Angriffslasche 14 für das Zwischenglied 13 aufweisenden Schwenkachse 4 bewirkt. In Figur 4 weist die Angriffslasche 14 an der Schwenkachse 4 eine Kurvenführung auf, in die ein Stellglied der Stellstange 12 eingreift und auf diese Weise die Drehung der Schwenkachse 4 bei Linearbewegung des Antriebselements 1 bewirkt.In particular, with reference to Figures 3 and 4, the adjusting mechanism 3, as mentioned, optionally designed as a toggle or as a cam mechanism. Figure 3 shows the toggle mechanism in which a connected to the drive element 1, linearly movable control rod 12 via an intermediate member 13, the rotational movement of an attack tab 14 for the intermediate member 13 having pivot axis 4 causes. In Figure 4, the attack tab 14 on the pivot axis 4 on a curve guide, in which an actuator of the actuating rod 12 engages and in this way causes the rotation of the pivot axis 4 in linear movement of the drive element 1.

Wie in Figur 1 andeutungsweise dargestellt, ist das Gehäuse 2 vorzugsweise in an sich bekannter Weise aus zwei zueinander spiegelsymmetrischen Schalen 8, 9 gebildet (siehe hierzu auch die bereits zitierte DE 196 16 441 C1); dabei ist die Maßgabe "spiegelsymmetrisch" weit auszulegen, d. h. es muss nicht jedes Detail spiegelsymmetrisch sein, sondern lediglich alle wesentlichen Merkmale, wie beispielsweise Bereiche zum Anbringen der Antriebsvorrichtung selbst oder zum Anbringen von weiteren Elementen an der Antriebsvorrichtung.As shown in Figure 1 suggestively, the housing 2 is preferably formed in a conventional manner from two mutually mirror-symmetrical shells 8, 9 (see also the already cited DE 196 16 441 C1); while the proviso "mirror-symmetric" is interpreted broadly, d. H. not every detail has to be mirror-symmetrical, but only all essential features, such as areas for attaching the drive device itself or for attaching further elements to the drive device.

Wesentlich für die erfindungsgemäße Antriebsvorrichtung ist nun, dass am Gehäuse 2 ein zusatzgehäuse 6 fest, aber lösbar angeordnet ist, wobei im Zusatzgehäuse 6 eine weitere Stellmechanik 7 vorgesehen ist, die einerseits mit der Schwenkachse 4 und andererseits mit dem am zusatzgehäuse 6 angeordneten Werkzeug 5 wirkverbunden ist.Essential for the drive device according to the invention is now that on the housing 2 an additional housing 6 fixed, but releasably disposed, wherein the additional housing 6, a further adjusting mechanism 7 is provided, which is operatively connected on the one hand with the pivot axis 4 and on the other hand with the additional housing 6 arranged on the tool 5.

Figur 1 zeigt die Antriebsvorrichtung mit dem erfindungsgemässen zusatzgehäuse 6, wobei bei diesem Ausführungsbeispiel als Werkzeug 5 ein sogenannter Zentrierspanner vorgesehen ist.Figure 1 shows the drive device with the inventive additional housing 6, wherein in this embodiment, a so-called centering is provided as a tool 5.

Je nach dem, ob nur an einer oder an beiden Seiten ein Werkzeug an der Schwenkachse 4 angebracht werden soll, ist ferner in an sich bekannter Weise vorteilhaft vorgesehen, dass die Schwenkachse 4 wahlweise ein- oder beidseitig aus dem Gehäuse 2 heraussteht (siehe hierzu insbesondere Figur 2). Für den Fall, dass sich das Zusatzgehäuse 6, wie in Figur 10 dargestellt, unmittelbar an das die Schwenkachse 4 aufnehmende Gehäuse 2 anschließt (bei dieser Lösung ist ein geringfügig grösserer Aufwand beim Wechsel des Zusatzmoduls erforderlich), ist im übrigen vorteilhaft vorgesehen, dass die Schwenkachse 4 überhaupt nicht aus dem Gehäuse 2 heraussteht, aber stattdessen zwei Angriffslaschen (14, 16) aufweist, die jeweils mit einer der beiden Stellmechaniken (3, 7) verbunden sind, d. h. letztlich wird auch bei geforderter linearer Bewegung des Werkzeugs 5 die lineare Bewegung des Antriebselements 1 zunächst über die Schwenkachse 4 in eine Drehbewegung umgesetzt und erst anschließend wieder in eine Linearbewegung transformiert.Depending on whether a tool is to be mounted on the pivot axis 4 only on one or both sides, it is furthermore advantageously provided in a manner known per se for the pivot axis 4 to protrude from the housing 2 selectively on one or both sides (see in particular Figure 2). In the event that the additional housing 6, as shown in Figure 10, directly to the pivot axis 4 accommodating housing 2 connects (in this solution, a slightly greater effort when changing the additional module is required), it is otherwise advantageous that the Swivel axis 4 does not stick out of the housing 2, but instead has two attack tabs (14, 16), which are each connected to one of the two adjusting mechanisms (3, 7), d. H. Ultimately, even when required linear movement of the tool 5, the linear movement of the drive element 1 is first converted via the pivot axis 4 in a rotary motion and only then transformed back into a linear motion.

Das Zusatzgehäuse 6 wird mit entsprechend geeigneten Befestigungsmitteln (beispielsweise Verbindungselemente wie Schrauben oder Flanschflächen) am Gehäuse 2 der Antriebsvorrichtung befestigt, wobei beide Gehäuse 2, 6 zueinander entsprechend angepaßt ausgebildet sind. Darüber hinaus ist vorteilhaft vorgesehen, dass das Zusatzgehäuse 6 zwei zueinander (wiederum im wesentlichen) spiegelsymmetrischen, vorzugsweise schalenartige Deckel 10, 11 aufweist und vorzugsweise mit einem Mittelteil 15 versehen ist, in dem die Stellmechanik 7 und an dem beidseitig jeweils einer der Deckel 10, 11 angeordnet ist. Diese Maßgabe führt zu vielseitigen Montagemöglichkeiten an allen Seiten der Antriebsvorrichtung.The additional housing 6 is fastened with correspondingly suitable fastening means (for example connecting elements such as screws or flange surfaces) on the housing 2 of the drive device, wherein both housings 2, 6 are adapted to one another in a corresponding manner. In addition, it is advantageously provided that the additional housing 6 has two mutually (again substantially) mirror-symmetrical, preferably shell-like cover 10, 11 and is preferably provided with a central part 15, in which the adjusting mechanism 7 and on the both sides of each of the lid 10, 11 is arranged. This requirement leads to versatile mounting options on all sides of the drive device.

Bei seitlicher Anordnung des erfindungsgemäßen Zusatzmoduls steht an der Schnittstelle zwischen den beiden Gehäusen 2, 6 die vom Antriebselemente 1 angetriebene Schwenkachse 2 bei den Ausführungen gemäß der Figuren 1 bis 9 soweit heraus, dass sie in die Stellmechanik 7 des Zusatzmoduls eingreifen kann. Dies verdeutlichen insbesondere die Figuren 5 bis 9.In the lateral arrangement of the additional module according to the invention is at the interface between the two housings 2, 6 driven by the drive elements 1 pivot axis 2 in the embodiments of Figures 1 to 9 so far out that they can engage in the control mechanism 7 of the additional module. This is illustrated in particular by FIGS. 5 to 9.

Ferner ist gemäß den Figuren 5 bis 9 vorteilhaft vorgesehen, dass das Zusatzgehäuse 6 in unterschiedlichen Positionen - mit der Schwenkachse 4 als Rotationsachse - seitlich am Gehäuse 2 befestigbar ist.Furthermore, it is advantageously provided according to FIGS. 5 to 9 that the additional housing 6 can be fastened laterally to the housing 2 in different positions-with the pivot axis 4 as rotation axis.

Gemäß der Ausführungsform nach Figur 7 ist ferner zur Befestigung der Antriebsvorrichtung an entsprechenden Konsolen oder dergleichen vorteilhaft vorgesehen, dass wahlweise am Gehäuse 2 und/oder am Zusatzgehäuse 6 mindestens eine Befestigungsebene 17 vorgesehen ist. Derartige Befestigungsebenen an Spannvorrichtungen sind beispielsweise auch aus der bereits zitierten DE 196 16 441 C1 bekannt. Sie sind vorzugsweise als rechteckige Ausnehmung mit Verbindungsmitteln (zum Beispiel Gewindebohrungen) am Gebäuse 2 bzw. am Zusatzgehäuse 6 ausgebildet. Wie Figur 7 zu entnehmen ist, kann eine solche Befestigungsebene 17 beidseitig an den Längsseiten des Gehäuses der Spannvorrichtung, am Kopf der Spannvorrichtung und/oder beidseitig am Zusatzgehäuse 6 vorgesehen sein.According to the embodiment according to FIG. 7, it is furthermore advantageously provided for fastening the drive device to corresponding brackets or the like that optionally at least one fastening plane 17 is provided on the housing 2 and / or on the additional housing 6. Such attachment levels of fixtures are known for example from the already cited DE 196 16 441 C1. They are preferably designed as a rectangular recess with connecting means (for example threaded bores) on the housing 2 or on the additional housing 6. As can be seen from FIG. 7, such a fastening plane 17 can be provided on both sides on the longitudinal sides of the housing of the tensioning device, on the head of the tensioning device and / or on the additional housing 6 on both sides.

Aus den Figuren 1 bis 10 geht dabei schließlich anschaulich ein wesentlicher Vorteil der erfindungsgemäßen Antriebsvorrichtung hervor. Als Antrieb wird, wie oben erwähnt, eine an sich bekannte Antriebsvorrichtung gemäß Figur 2, aber auch 9 verwendet. Im Bereich der Schwenkachse 4 (an der sonst, wie in den Figuren 3 und 4 dargestellt, ein Spannarm befestigt ist) wird dann je nach Anwendungsfall ein entsprechend geeignetes Zusatzmodul angefügt, also beispielsweise ein Schubstangen-(Figur 5), Unterflur- (Figur 6), Zentrier- (Figur 7, 9, 11) oder Schwenkspanner (Figur 8). Dabei ist die Stellmechanik 7 im Zusatzgehäuse 6 vorzugsweise wie dargestellt zur Umsetzung der Drehbewegung der Schwenkachse 4 in wahlweise eine Dreh- oder eine Linearbewegung vorgesehen.From FIGS. 1 to 10, finally, an essential advantage of the drive device according to the invention is clearly shown. As drive, as mentioned above, a known drive device according to Figure 2, but also 9 is used. In the region of the pivot axis 4 (on which otherwise, as shown in Figures 3 and 4, a clamping arm is attached) then a correspondingly suitable additional module is added depending on the application, so for example a push rod (Figure 5), underfloor (Figure 6 ), Centering (Figure 7, 9, 11) or swing clamp (Figure 8). The adjusting mechanism 7 in the additional housing 6 is preferably provided as shown for implementing the rotational movement of the pivot axis 4 in either a rotary or a linear movement.
