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.
Eine Spannvorrichtung der eingangs genannten Art ist nach der DE 197 51 950 C1 bekannt. Diese besteht aus einem linear beweglichen Antriebselement (Pneumatikzylinder), das zur Betätigung von mindestens einem Spannwerkzeug (Spannarm) über eine in einem Gehäuse angeordnete Stellmechanik (Kniehebelmechanik) mit einer im Gehäuse drehbar gelagerten Schwenkachse wirkverbunden ist. Am Gehäuse ist beidseitig jeweils ein Drehlagerbereiche (Radial- und Axiallager) für die Schwenkachse vorgesehen, zwischen denen die Kniehebelmechanik angeordnet ist. Die Schwenkachse ist zur Anbringung des Spannarmes über einen Drehlagerbereich hinausragend ausgebildet.A clamping device of the type mentioned is known from DE 197 51 950 C1. This consists of a linearly movable drive element (pneumatic cylinder), which is operatively connected to the actuation of at least one clamping tool (clamping arm) via a housing arranged in a control mechanism (toggle mechanism) with a rotatably mounted in the housing pivot axis. On the housing on both sides in each case a pivot bearing areas (radial and thrust bearing) is provided for the pivot axis, between which the toggle lever mechanism is arranged. The pivot axis is formed for mounting the clamping arm over a pivot bearing area protruding.
In Abänderung hierzu kann die Schwenkachse gemäß der DE 197 51 950 C1 (siehe Spalte 3, Zeile 53 ff.) auch an beiden Endabschnitten aus dem Gehäuse des Spannkopfes herausgeführt sein und auf diesen beiden Endabschnitten beispielsweise einen gabelförmig gestalteten Spannarm tragen.In a modification to this, the pivot axis according to DE 197 51 950 C1 (see
Zur Realisierung dieser Abänderung ist es bei der Spannvorrichtung gemäß der DE 197 51 950 C1 erforderlich, die Spannvorrichtung auseinander- und eine für den jeweiligen Anwendungsfall passende Schwenkachse einzubauen. Im Falle eines seitlichen Spannarmes also eine Schwenkachse, die nur einseitig aus dem Gehäuse herausgeführt ist, im Falle eines gabelförmigen Spannarmes eine, die beidseitig aus dem Gebäuse heraussteht.To implement this modification, it is necessary in the clamping device according to DE 197 51 950 C1, the tensioning device apart and install a suitable for the particular application pivot axis. In the case of a lateral clamping arm so a pivot axis, which is led out only on one side of the housing, in the case of a fork-shaped clamping arm one that protrudes from both sides of the housing.
Die Abänderung hinsichtlich der Anordnung der Schwenkachse ist somit nachteilig mit umfangreichen Umbaumaßnahmen verbunden.The change in the arrangement of the pivot axis is thus disadvantageously associated with extensive conversion measures.
Der Vollständigkeit halber wird noch auf die EP 0 862 970 A2 hingewiesen.For the sake of completeness, reference is made to EP 0 862 970 A2.
Der Erfindung liegt die Aufgabe zugrunde, bei einer Spannvorrichtung der eingangs genannten Art den Aufwand zur Umrüstung bezüglich der Anordnung der Schwenkachse auf konstruktiv möglichst einfache Weise zu reduzieren.The invention has for its object to reduce in a tensioning device of the type mentioned the cost of retrofitting with respect to the arrangement of the pivot axis in a structurally simple manner possible.
Diese Aufgabe ist gelöst mit einer Spannvorrichtung der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale.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 die Schwenkachse aus einer Hohlwelle und einer in dieser konzentrisch und zu dieser verdrehfest angeordneten Abtriebswelle gebildet ist, wobei die Hohlwelle (etwa) gehäusebreit ausgebildet und in den Drehlagerbereichen verdrehbar gelagert ist und wobei die Abtriebswelle zur Hohlwelle axialverschieblich, aber an dieser fixierbar ausgebildet ist. Mit anderen Worten ausgedrückt, ist die erfindungsgemäße Schwenkachse im Gegensatz zur eingangs beschriebenen Achse nach der DE 197 51 950 C1 mindestens zweiteilig ausgebildet, wobei der mit der Stellmechanik verbundene Teil im Prinzip als drehbar im Gehäuse angeordnete Hohlwelle und der andere Teil als in der Hohlwelle verdrehfest, aber axialverschieblich und -fixierbar ausgebildet ist. Je nach Bedarf, wird also die Abtriebswelle bezüglich ihrer Axialfixierung von der Hohlwelle gelöst und in die jeweils gewünschte Position gebracht. Dabei weist die Hohlwelle etwa die Breite des Gehäuses auf. Die Abtriebswelle weist vorzugsweise eine Breite auf, die es ermöglicht, einerseits bei einseitigem Überstand einen Spannarm und andererseits bei beidseitigem Überstand beispielsweise einen gabelförmigen Spannarm daran zu befestigen. Für andere Anwendungsfälle, beispielsweise wenn die Drehbewegung der Hohlwelle per Kardanwelle weiter übertragen wird, kann die Abtriebswelle auch länger oder gegebenenfalls auch kürzer ausgebildet sein. Entscheidend ist, dass zur Abänderung lediglich die Abtriebswelle wahlweise ausgetauscht oder auch nur in ihrer Axialposition verschoben werden muss.According to the invention, it is thus provided that the pivot axis is formed by a hollow shaft and an output shaft concentric therewith and rotationally fixed therewith, wherein the hollow shaft (approximately) is formed as wide as a housing and is rotatably mounted in the pivot bearing regions and wherein the output shaft is axially displaceable relative to the hollow shaft, but is designed to be fixable. In other words, the pivot axis according to the invention, in contrast to the axis described in DE 197 51 950 C1 at least two parts, wherein the part connected to the adjusting mechanism in principle rotatable in the housing arranged hollow shaft and the other part as in the hollow shaft against rotation but is axially displaceable and fixable. Depending on requirements, so the output shaft is released with respect to their axial fixation of the hollow shaft and brought into the respective desired position. In this case, the hollow shaft has approximately the width of the housing. The output shaft preferably has a width which makes it possible, on the one hand, to fasten a tensioning arm on one side overhang and, on the other hand, in the case of a protrusion on both sides, for example attaching a forked tensioning arm to it. For other applications, for example, when the rotational movement of the hollow shaft is transmitted by propeller shaft, the output shaft may also be longer or possibly shorter. It is crucial that for modification, only the output shaft must either be replaced or moved only in its axial position.

Dieser Stellhebel ist über ein Schleppglied 18 mit dem Stellglied 19 des Antriebselements 1 wirkverbunden, d. h. eine lineare Bewegung des Stellgliedes 19 führt in bekannter Weise zu einer Drehbewegung der Schwenkachse 4 bzw. der Hohlwelle 8.To actuate the now two-
Wie die an sich bekannte Schwenkachse 4 weist auch die Hohlwelle 8 zur ihrer Lagerung im Gebäuse 2 vorzugsweise zumindest an den Drehlagerbereichen 6, 7 eine zu diesen größenangepaßte, zylindrische Aussenkontur auf, d. h. an diesen Stellen ist sie, wie beispielsweise in Figur 6 dargestellt, in dem oben beschriebenen Radial-Axial-Lager gelagert. Eine Wellenschulter 20 an der Hohlwelle stützt sich beidseitig jeweils an den Lagern ab.Like the known

Abtriebswellenseitig ist demenstsprechend vorgesehen, dass die Abtriebswelle 9 einen Befestigungsmechanismus 14 aufweist.

Zur Justage der Abtriebswelle 9 wird diese also zunächst in die Hohlwelle 8 eingesteckt. Beispielsweise mittels eines Imbusschlüssels kann dann das von einer Seite der Abtriebswelle 9 zugängliche, schraubenförmige Verstellelement 16 gedreht und damit bezüglich der Abtriebswelle 9 axial verschoben werden. Durch diese Axialverschiebung und die konische Ausbildung des Verstellelements 16 werden die kugelförmigen Verrastungselemente 15 radial auseinander gepresst. Wie aus den Figuren 6 bis 10 ersichtlich, kann die Abtriebswelle 9 somit aufgrund der rasterförmig angeordneten Vertiefungen 13 in unterschiedlichsten Positionen fixiert werden.For adjusting the
