Abstract
Description
Die Erfindung betrifft eine Spannvorrichtung, die aus einem gabelartig ausgebildeten Spannkopf besteht, zwischen dessen Gabelteilen der schwenkbare Spannarm und diesen schwenkenden Gelenk- und Betätigungsglieder gelagert sind.The invention relates to a clamping device which consists of a fork-like clamping head, between the fork parts of which the pivotable clamping arm and these pivoting articulation and actuating members are mounted.
Spannvorrichtungen dieser Art sind allgemein bekannt und in Benutzung und dienen insbesondere zum Festspannen von zu bearbeitenden Werkstücken auf Werktischen oder besonders ausgebildeten Werkstückgestellen im Rahmen von insbesondere Serienfertigungen. Diese Spannvorrichtungen erfüllen hinsichtlich ihrer Betätigung und Spannfunktion die an sie zu stellenden Forderungen einer einwandfreien und dauerhaften Fixierung des Werkstückes auf ihrer Unterlage. Diese einwandfreie Funktion kann allerdings dann beeinträchtigt werden, wenn am betreffenden Werkstück spanabhebende Bearbeitungen vorzunehmen sind, wobei durchaus der Fall eintreten kann, daß Bearbeitungsspäne in die Stell mechanik derartiger Kniehebelspannvorrichtungen geraten. Wenn dabei feine Späne zwischen die Gelenkglieder geraten, kann dies zum Verklemmen der Gelenkglieder oder im krassen Fall sogar zur Beschädigung der betreffenden Vorrichtung führen, so daß diese ausgetauscht werden muß. Die Möglichkeit, daß Späne in die Betätigungsmechanik derartiger Spannvorrichtungen geraten können, ist dadurch gegeben, daß diese zwischen den Gabelteilen eines Spannkopfes der Vorrichtung gelagert ist und der Spalt zwischen den Gabelteilen völlig frei liegt, was auch notwendig ist, da der Stellweg des Spannhebels von seiner Spannstellung bis zur Rückstellposition frei sein muß, um die Schwenkbewegung des Spannarmes überhaupt bewirken zu können.Clamping devices of this type are generally known and in use and are used in particular for clamping workpieces to be machined on work tables or specially designed workpiece frames in the context of, in particular, series production. With regard to their actuation and clamping function, these clamping devices fulfill the requirements to be placed on them for a perfect and permanent fixation of the workpiece on their base. This flawless function can, however, be adversely affected if machining operations are to be carried out on the workpiece in question, and the case may well arise that machining chips get into the actuating mechanism of such toggle lever clamping devices. If fine chips get between the articulated members, this can lead to jamming of the articulated members or even damage to the device in question, so that it must be replaced. The possibility that chips can get into the actuation mechanism of such clamping devices is given by the fact that it is mounted between the fork parts of a clamping head of the device and the gap between the fork parts is completely free, which is also necessary because the travel of the clamping lever from it The clamping position up to the reset position must be free in order to be able to cause the pivoting movement of the clamping arm at all.
Nach DE-PS 31 51 618, DE-A 1122 346 und den US-PS 16 79 912, 21 90 213 und 25 51 860 ist es bereits bekannt, die Führungsschienen bzw. Führungsbetten von Werkzeugmaschinen durch ausziehbare Abdeckrollen abzudecken, was dort absolut unproblematisch ist, weil die geführten Schlitten einfache Hin- und Herbewegungen und keine Schwenkbewegungen ausführen, die ausziehbaren Abdeckbänder keine Spalte, sondern exponierte und damit mehr oder weniger freistehende Laufflächen abzudecken haben und kei-ne beengten Raumverhältnisse wie an Spannvorrichtungen vorliegen. Insoweit lassen sich also diese vorbekannten Abdeckschutzeinrichtungen nicht ohne weiteres auf Spannvorrichtungen der hier vorliegenden Art übertragenAccording to DE-PS 31 51 618, DE-A 1122 346 and US-PS 16 79 912, 21 90 213 and 25 51 860, it is already known to cover the guide rails or guide beds of machine tools by pull-out cover rollers, which is absolutely unproblematic there is because the guided slide easily floats and no pivoting movements run, the pull-out cover bands, no gaps, but exposed and therefore have to cover more or less detached treads and k e i-ne limited space as present on jigs. In this respect, these previously known protective cover devices cannot be easily transferred to tensioning devices of the type present here
Aufgrund der zu beachtenden Schwenkbewegung des Spannhebels im Spalt lassen sich auch nicht ohne weiteres beidseitig und wie vorbekannt am Schwenkhebel überdeckende Abdeckbänder befestigen.Due to the pivoting movement of the tensioning lever in the gap, covering tapes covering both sides and, as previously known, cannot easily be attached to the pivoting lever.
Der Erfindung liegt demgemäß die Aufgabe zugrunde, eine Spannvorrichtung der eingangs genannten Art unter Ausnutzung des an sich bekannten Abdeckprinzips dahingehend auszubilden, daß trotz der im Bereich des Spannkopfes der Vorrichtung beengten Raumverhältnisse und der Schwenkbewegung des Spannhebels um ca. 120° dieses Abdeckprinzip auch an derartigen Spannvorrichtungen nutzbar gemacht werden kann, um den Eintritt von Spänen od. dgl. Fremdkörpern in den Spalt zwischen die Gabelteile und damit zwischen die Gelenkglieder verhindern zu können.The invention is therefore based on the object of designing a tensioning device of the type mentioned using the known covering principle in such a way that, despite the confined space in the area of the tensioning head of the device and the pivoting movement of the tensioning lever by approximately 120 °, this covering principle also applies to such Clamping devices can be used to prevent the entry of chips or the like. Foreign bodies in the gap between the fork parts and thus between the joint members.
Diese Aufgabe ist mit einer Spannvorrichtung der eingangs genannten Art nach der Erfindung durch die im Kennzeichen des Hauptanspruches angeführten Merkmale gelöst. Praktische und vorteilhafte Auführungsformen ergeben sich nach den Unteransprüchen.This object is with a clamping device of the type mentioned according to the invention by the in the characterizing part of the main claim characteristics solved. Practical and advantageous forms of performance result from the subclaims.
Aufgrund der beengtenRaumverhältnisse an derartigen Vorrichtungen und in Rücksicht auf Schwenkbewegungen um ca. 1200hätte es sich an sich angeboten, den ganzen Spannkopf bspw. mit einer elastischen glockenartigen Gummimanschette abzudecken, die vom Spannarm durchgriffen wird, hierbei und unter Berücksichtigung der ständigen Schwenkbewegungen des Spannarmes und des rauhen Betriebes im Rahmen einer Serienfertigung wäre aber zu erwarten, daß derartige Abdeckmanschetten einer Dauerbelastung nicht lange standhielten. Demgegenüber besteht der erfindungsgemäße Vorschlag in der Abdeckung des Spaltes mittels eines elastischen Abdeckelementes mindestens auf der spannfernen Seite, wobei hier unter elastischem Abdeckelement ein solches zu verstehen ist, das nicht durch Späne od. dgl. Fremdkörper beschädigt werden kann und somit aus einem dünnwandigen federelastischen metallischen Material besteht. Das Rollfederband sitzt also als kleines Rollo innerhalb des Spannkopfes und nimmt an der Bewegung desSpannarmes teil, der beim Einschwenken in die Spannstellung das Rollo aus- und mit um die Ecke zieht und die darunter bzw. dahinter befindlichen Gelenkglieder und Gelenke abdeckt. Vorteilhaft kann auch auf der Spannseite am Spalt zwischen den Gabelteilen ein bis zur Spannstellung desSpannarmes reichendes Abdeckelement angeordnet sein bspw. in Form einer federnden Zunge, die sich im Spalt erstreckt oder auch außen am Spannkopf anliegen kann. Diese Außenanlage des Abdeckelementes wäre auch für das Rollfederband möglich, allerdings kann dann die Rollo-Lagerung nicht innerhalb des Spaltes untergebracht werden.Due to the confined space on such devices and in view of pivoting movements around 120 0 , it would have been appropriate to cover the entire clamping head, for example, with an elastic bell-like rubber sleeve, which is penetrated by the clamping arm, taking into account the constant pivoting movements of the clamping arm and the rough operation in the context of series production would, however, be expected that such cover sleeves would not withstand long-term stress. In contrast, the proposal according to the invention consists in covering the gap by means of an elastic cover element at least on the distant side, here an elastic cover element is to be understood as one that cannot be damaged by chips or the like. Foreign bodies and thus consists of a thin-walled, spring-elastic metallic Material exists. The roller spring band sits as a small roller blind inside the clamping head and takes part in the movement of the clamping arm, which pulls the roller blind out and around the corner when it is swiveled into the clamping position and covers the articulated members and joints located below or behind it. A covering element extending to the clamping position of the clamping arm can also advantageously be arranged on the clamping side at the gap between the fork parts, for example in the form of a resilient tongue which extends in the gap or can also bear against the outside of the clamping head. This outside arrangement of the cover element would also be possible for the roll spring band, but then the roller blind storage cannot be accommodated within the gap.
Eine Außenanlage des Abdeckelementes an der Vorrichtung ist jedoch dann möglich, wenn diese derart ausgebildet wird, daß das Abdeckelement in seiner Breite größer als die Breite des Spaltes bemessen und mit einer Spanmrmdurchgriffsöffnung versehen und an beiden Seiten des Spannkopfes, den Spalt abdeckend, ein- bzw. ausrollbar gelagert ist. Zweckmäßig ist dabei der Spannkopf an seinen freien Enden, d.h. an den Gabelteilen mit Abrundungen versehen, damit sich das Abdeckelement gut über die freien Enden bewegen läßt. Da der Spannanndas Abdeckelement durchgreift, nimmt auch hier das Abdeckelement an der Bewegung des Spannarmes teil, wobei der Abzug des Abdeckelementes auf der einen Seite mit einem Abrollen und auf der anderen Seite mit einem Einrollen verbunden ist.However, an external contact of the cover element on the device is possible if it is designed in such a way that the width of the cover element is greater than the width of the gap and provided with a Spanmrm penetration opening and on or on both sides of the clamping head, covering the gap is rolled out. The clamping head is expedient at its free ends, i.e. Round the fork parts so that the cover element can be easily moved over the free ends. Since the tensioning element reaches through the covering element, the covering element also takes part in the movement of the tensioning arm, the withdrawal of the covering element being connected on one side to rolling and on the other side to rolling up.
Die erfindungsgemäße . Spannvorrichtung wird nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.The invention. Clamping device is explained in more detail below with reference to the drawing of exemplary embodiments.

- Fgi. 4 in perspective a special embodiment of the tensioning device.
Wie aus Fig. 1 bis 3 erkennbar, besteht die Kniehebelspannvorrichtung aus einem gabelartig ausgebildeten Spannkopf 6, zwischen dessen Gabelteilen 3 der Spannarm 1 und die diesen schwenkenden Gelenk-und Betätigungsglieder gelagert sind, die keiner näheren Erläuterung bedürfen, da diese Elemente in ihrer Anordnung und Funktion hinlänglich bekannt sind.Beim dargestellten Ausführungsbeispiel erfolgt der Antrieb der Spannvorrichtung mittels eines hydraulisch oder pneumatisch betätigbaren Antriebszylinder 11. Wie aus Fig. 1 erkennbar, ist der die Gelenk- und Betätigungsglieder und das gelagerte Ende des Spannarmes 1 aufnehmende Spalt 2 zwischen den Gelenkteilen 3 mit einem elastischen Abdeckelement 4 auf der spannfernen Seite 5 abgedeckt, wobei das Abdeckelenent 4 mit einer Länge versehen ist, die der maximalen Länge des Spaltes 2 bei Spannstellung des Spannhebels 1 entspricht. Dabei ist das Abdeckelement 4 in Form eines Rollfederbandes 4' ausgebildet, das mit seinem aufrollbaren Ende am Spannkopf 6! Junterhalb der Rückstellposition des Spannarmes 1 gelagert und mit seinem freien Ende 7 am gelenknahen Ende des Spannarmes 1 befestigt ist. In der Rückstellposition I gemäß Fig. 1 ist das Rollfederband auf seiner entsprechend federbelasteten Aufnahmerolle 12 aufgerollt und in Spannstellung II entsprechend weit ausgezogen, und verläuft im Spalt 2,wie gestrichelt angedeutet. Auf der Spannseite 5' ist am Spalte 2 zwischen den Gabelteilen 3 ein bis zur Spannstellung des Spannarmes 1 reichendes Abdeckelement in geeigneter Weise befestigt und deckt den Spalt 2 auch von dieser Seite ab. Im übrigen kann auf dieser Seite ebenfalls für dieses Abdeckelement 8 das Rollo-Prinzip angewendet werden, das auf dieser Seite wesentlich kürzer gehalten werden kann, da hier der Stellweg entsprechend kurz ist.As can be seen from FIGS. 1 to 3, the toggle lever clamping device consists of a fork-
Anknüpfend an das beidseitige Rollo-Prinzip kann gem. Fig. 4 die Vorrichtung auch derart ausgebildet sein, daß das Abdeckelement 4 in seiner Breite größer als die Breit des Spaltes 2 bemessen und mit einer Spannarmdurchgriffsöffnung 9 versehen ist. Das Abdeckelement 4 bildet hierbei also ein durchgehendes Band, dessen Enden auf beiden Seiten am kleinen Rollowellen gelagert sind, deren Federspannung jeweils entgegengesetzt gerichtet ist. Da der Spannarm 1 das Rollfederband 4 durchgreift, macht dieses Federband die Bewegung des Spannarmes 1 automatisch mit, wobei der Auszug auf der einen Seite mit einem Einrollen auf der anderen Seite verbunden ist und umgekehrt. Da der Spannarm praktisch bei allen bekannten Ausführungsformen derartiger Spannvorrichtungen in seiner Breite mit geringem Untermaß der Breite des Spaltes 2 entspricht, verlangt die Anordnung der Durchgriffsöffnung, daß das Rollfederband breiter gehalten wird als der Spalt, was bedeutet, daß das Rollfederband bei dieser Ausführungsform sich nicht innerhalb des Spaltes 2 erstrecken kann, sondern über die Flanken an den freien Enden 3' der Gabelteile 3 verläuft, die dafür zweckmäßig und beidseitig mit Abrundungen lo versehen sind. Wie in Fig. 4 angedeutet, it es dabei ohne weiteres möglich, die kleinen Rollowalzen, räumlich nach außen nicht auftragend, in den Spannkopf mit einzubeziehen, wofür die Gabelteile mit entsprechenden Ausnehmungen 13 versehen sind, in denen die kleinen Rollowellen (nicht dargestellt) gelagert sind.Following the double-sided roller blind principle, according to Fig. 4, the device can also be designed such that the width of the
