Abstract
Description
Die Erfindung betrifft eine Kniehebelspannvorrichtung, bestehend aus einem eine mit einem Spannarm gekoppelten Kniehebelstellmechanik enthaltendes Kopfstück, in dem ein an der Stellmechanik angelenktes, mindestens aus zwei Teilen gebildetes, linear bewegliches und längenveränderliches Stellglied eines Kolbenantriebes angeordnet ist. Solche Kniehebelspannvorrichtungen sind z.B. aus EP 0908272 A1 und EP 1179394 A2 zu entnehmen.The invention relates to a toggle lever device consisting from a toggle lever mechanism coupled to a clamp arm containing headpiece in which one on the adjusting mechanism hinged, at least two parts formed, linearly movable and variable-length actuator of a Piston drive is arranged. Such toggle clamps are e.g. from EP 0908272 A1 and EP 1179394 A2 remove.
Solche modernen Spannvorrichtungen sind in der Regel im Kopfstück auch mit sogenannten Endstellungsabfrageeinrichtungen ausgestattet, die von Gebern am Stellglied zur Wirkung gebracht werden, und außerdem sind ebenfalls in der Regel der Kolben des Antriebes und der Boden des den Kolben aufnehmenden Zylinders mit die Öffnungsstellung des Spannarmes dämpfenden Elementen ausgestattet.Such modern clamping devices are usually in the head piece also with so-called Endstellungsabfrageeinrichtungen equipped, brought by donors on the actuator to act and also are also usually the piston of the Drive and the bottom of the piston receiving the cylinder with the opening position of the tensioning arm damping elements fitted.
Derartige Kniehebelspannvorrichtungen sind hinlänglich bekannt
und in Benutzung, so daß es diesbezüglich an sich keines besonderen
druckschriftlichen Nachweises bedarf. Nur bspw. sei
verwiesen auf die EP 0 925 877 A3, das DE 30 22 376 A1, die US
4,793,602 und die EP 0 908 272 A1. Solche Spannvorrichtungen
kommen in Vielzahl insbesondere in Fertigungsstraßen der Automobilindustrie
bei der Karosserieherstellung zum Einsatz.
Was dabei die vorerwähnten, die Öffnungsstellung des Spannarmes
dämpfenden Elemente betrifft, so handelt es sich dabei in der
Regel um einen unterhalb des doppelseitig beaufschlagbaren
Kolbens angeordneten Tauchfortsatz, dem im Boden des den Kolben
enthaltenen Zylinders eine passende, reduziert entlüftbare
Sackbohrung zugeordnet ist. Eine solche Dämpfung für die Öffnungsstellung
des Spannarmes ist in der Regel gewünscht und
erforderlich, um die ganze Vorrichtung belastende Rückstellungsschläge
zu vermeiden bzw. zu dämpfen. Such toggle clamping devices are well known and in use, so that in this regard, no special printed evidence required. For example, reference is made to EP 0 925 877 A3, DE 30 22 376 A1, US Pat. No. 4,793,602 and EP 0 908 272 A1. Such clamping devices are used in a variety of particular production lines in the automotive industry in the body manufacturing.
What concerns the aforementioned, the opening position of the tensioning arm damping elements, so it is usually a arranged below the double-acting piston plunger extension, which is associated with a suitable, reduced ventable blind bore in the bottom of the cylinder contained the piston. Such damping for the opening position of the tensioning arm is usually desired and required to avoid or dampen the entire device loading restitution shocks.
Bei den Gegenständen der oben genannten ersten drei Druckschriften handelt es sich um Spannvorrichtungen mit ebenfalls linear beweglichen Stellgliedern, die mehrteilig ausgebildet sind, wobei zwischen zwei mit axialen Gewindelöchern versehenen Teilen der Stellglieder mit entsprechenden Außengewinden versehene Zwischenstücke zwecks Verbindung der betreffenden Teile eingeschraubt sind. Damit ist eine gewisse Feineinstellung bzgl. der Endstellungen der Spannarme möglich. Nach dem gleichen Prinzip ist auch das Stellglied der Spannvorrichtung nach der zuletzt genannten EP 0 908 272 A1 gestaltet, wobei jedoch die axiale Innengewindebohrung im Stellglied und auch das durch Einschrauben anzuschließende Teil des Stellgliedes wesentlich länger bemessen sind, um damit einen mehr oder weniger großen Öffnungswinkel des zur Spannvorrichtung gehörenden Spannarmes einstellen zu können. Dies funktioniert zwar, hat aber zwei wesentliche Nachteile. Da an der Verstellung Gewinde beteiligt sind, ist einerseits zwar eine sehr feinfühlige Längenveränderung des Stellgliedes möglich, die aber andererseits einer großzügigen und einfachen Umstellung auf einen großen Öffnungswinkel und umgekehrt entgegensteht, zumal es in der Regel genügt, solche Öffnungswinkel in relativ groben Stellschritten von bspw. 15° vorzunehmen. Der zweite Nachteil besteht darin, daß die Verstellung ohne eine Mindestdemontage der Spannvorrichtung nicht möglich ist, d.h., der Antriebszylinder muß vom Spannerkopfstück gelöst werden, um den zum Antriebszylinder bzw. dessen Kolben gehörenden Teil des Stellgliedes mit dem anderen Teil des Stellgliedes durch schraubende Drehung verstellen zu können, wobei es außerdem noch einer Gegenhaltekraft bedarf.In the articles of the above first three pamphlets are clamping devices with also linearly movable actuators, which are designed in several parts are, between two provided with axial threaded holes Dividing the actuators with corresponding external threads provided intermediate pieces for the purpose of connecting the relevant Parts are screwed in. This is a certain fine adjustment regarding the end positions of the clamping arms possible. To The same principle is also the actuator of the clamping device designed according to the last mentioned EP 0 908 272 A1, however, the axial internal threaded bore in the actuator and also to be connected by screwing part of the actuator are much longer, so that one more or less large opening angle of the tensioning device to be able to adjust the corresponding clamping arm. This works Although, but has two major disadvantages. Because of the adjustment Thread are involved, on the one hand, though a very sensitive change in length of the actuator possible, the but on the other hand a generous and easy changeover opposes a large opening angle and vice versa, especially since it is usually sufficient, such opening angle in relative rough adjustment steps of, for example, 15 ° make. The second Disadvantage is that the adjustment without a minimum disassembly the tensioning device is not possible, that is, the Drive cylinder must be released from the tensioning head piece to the to the drive cylinder or its piston belonging part of Actuator with the other part of the actuator screwing rotation can be adjusted, and it also still requires a holding force.
Ausgehend von Spannvorrichtungen der eingangs genannten Art liegt der Erfindung die Aufgabe zugrunde, diese dahingehend umzugestalten und zu vereinfachen, daß eine Öffnungswinkelverstellung des zur Spannvorrichtung gehörenden Spannarmes schnell und einfach durchführbar ist. Starting from clamping devices of the type mentioned The invention is based on the object, this effect to reshape and simplify that an opening angle adjustment of the clamping device belonging to the clamping arm fast and easy to carry out.
Diese Aufgabe ist mit einer Spannvorrichtung der eingangs genannten
Art nach der Erfindung gemäß Patentanspruch 1 dadurch
gelöst, daß die beiden das linare Stellglied bildenden Teile
sich überlappend ausgebildet und an ihren gegeneinander anliegenden
Flanken mit sich entsprechenden Verzahnungen versehen
sind und daß das spannarmseitige Teil an seinem unteren
Endbereich mit einer Verschraubungsbohrung und das andere, mit
dem Kolbenantrieb in Verbindung stehende Teil mit einem axial
orientierten Durchgriffsschlitz versehen ist, wobei die Verschraubungsbohrung
und der Durchgriffsschlitz von einer Querverschraubung
durchgriffen sind.This object is achieved with a clamping device of the aforementioned
Type according to the invention according to
Durch diese erfindungsgemäße Ausbildung ist bspw. ausgehend von einer maximalen Öffnungsstellung des Spannarmes, bei der die beiden Teile über die volle Länge der Verzahnungen im Eingriff stehen und bei der der Kolben im Antriebszylinder seine tiefste Stellung hat, sehr schnell und komplikationslos lediglich nach Anlösen (wird noch näher erläutert) der Verschraubung ein kleinerer Öffnungswinkel einstellbar, indem einfach das spannarmseitige Teil durch relativ geringes Abschwenken und damit Ausrasten seiner Verzahnung aus der des anderen Teil gelöst und vom Spannarm aus auf den gewünschten kleineren Öffnungswinkel nach oben bewegt und in dieser neuen, kleineren Öffnungsstellung in der Gegenverzahnung verrastet und mit der Querverschraubung fixiert wird.By this embodiment of the invention is, for example. Starting from a maximum opening position of the clamping arm, in which the both parts over the full length of the gears engaged stand and in which the piston in the drive cylinder its deepest Position has, very quickly and without complications only after Release (will be explained in more detail) of the screw connection Smaller opening angle adjustable by simply the tension arm side Part by relatively small pivoting and thus Disengage his gearing from that of the other part and release from the clamping arm to the desired smaller opening angle moved up and in this new, smaller opening position latched in the counter teeth and with the cross screw is fixed.
Die Verzahnung am spannarmseitigen Teil ist nur an dessen unterem Endbereich angeordnet. Damit wird vorteilhaft der für die Verzahnungsentrastung notwendige Ausschwenkbreich dieses Teiles begrenzt.The teeth on the tension arm side part is only on the lower part End area arranged. This is advantageous for the Verzahnungstrastung necessary Ausschwenkbreich this part limited.
Die Querverschraubung ist aus einer in die Verschraubungsbohrung eingeführten und den Durchgriffsschlitz durchgreifenden Imbus-Kopfschraube gebildet, an deren aus dem Schlitz herausragendem Ende eine Mutter angeordnet und diese verdrehgesichert im Kopfstück der Vorrichtung geführt ist. The cross screw is from a in the screw hole introduced and the penetration slot through Imbus cap screw formed at the out of the slot outstanding mother arranged a nut and this secured against rotation is guided in the head of the device.
Durch diese Aus- bzw. Weiterbildung bedarf es bei gewünschter Verstellung nur eines passenden Imbus-Steckschlüssels, um die Schraube etwas aus ihrer Mutter herauszuschrauben, d.h., die Verschraubung wird nur "angelöst", d.h., nicht vollständig getrennt und verbleibt damit vorteilhaft zwischen den beiden Teilen und hält diese auch bei der Verstellung zusammen.By this education or training it is required Adjusting only a suitable Allen socket to the Screw something out of its nut, that is, the Screwing is only "solved", that is not completely separated and thus remains advantageously between the two Sharing and keeping it together in the adjustment.
Um außerdem die beiden Verzahnungen in der jeweils gewünschten Stellung komplikationslos wieder in Eingriff bringen zu können, sind deren Zähne vorteilhaft mit abgerundeten oder angephasten Kanten versehen, wobei außerdem darauf hingewiesen sei, daß die Zähne in Verrastungsstellung durchaus zueinander ein gewisses Spiel haben können, da ein solches Spiel praktisch keine Auswirkung auf den eingestellten Öffnungswinkel hat.In addition, the two gears in the respectively desired Position without complications, their teeth are advantageous with rounded or chamfered Edges provided, it being also noted that the Teeth in Verrastungsstellung quite a bit to each other Game, because such a game is practically nonexistent Has an effect on the set opening angle.
Die erfindungsgemäße Spannvorrichtung und deren vorteilhaften Ausführungs- und Weiterbildungsformen gemäß der abhängigen Patentansprüche werden nachfolgend näher erläutert.The tensioning device according to the invention and its advantageous Forms of training and further education according to the dependent Claims are explained in more detail below.

Die Spannvorrichtung besteht nach wie vor und unter Verweis auf
die FIG.1,2 aus einem eine mit einem Spannarm 1 gekoppelten
Kniehebelstellmechanik 2 enthaltendes Kopfstück 3, in dem ein
an der Mechanik 2 angelenktes, mindestens aus zwei Teilen 4,5
gebildetes, linear bewegliches und längenveränderliches Stellglied
6 eines Kolbenantriebes 7 angeordnet ist.
Solche Spannvorrichtungen sind in der Regel im Kopfstück 3 auch
mit sogenannten Endstellungsabfrageeinrichtungen ausgestattet,
die von Gebern G am Stellglied 6 zur Wirkung gebracht werden.
Da solche Einrichtungen grundsätzlich bekannt sind, ist deren
nähere Erläuterung und Darstellung entbehrlich.The tensioning device consists, as before and with reference to FIGS. 1, 2, of a
Such clamping devices are generally equipped in the
Für eine solche Spannvorrichtung ist nun, ebenfalls unter Verweis
auf die Fig.1,2 wesentlich, daß die beiden das linare
Stellglied 6 bildenden Teile 4,5 sich, wie dargestellt, überlappend
ausgebildet und an ihren gegeneinander anliegenden
Flanken 8 mit sich entsprechenden Verzahnungen 9 versehen sind.
Dabei ist das spannarmseitige Teil 5 an seinem unteren Endbereich
10 mit einer Verschraubungsbohrung 11 (siehe Fig.5) und
das andere, mit dem Kolbenantrieb 7 in Verbindung stehende Teil
4 mit einem axial orientierten Durchgriffsschlitz 12 (siehe
Fig.5,6) versehen. Ferner sind dabei die Verschraubungsbohrung
11 und der Durchgriffsschlitz 12 von einer Querverschraubung 13
durchgriffen, mit der die jeweils eingestellte Verrastungsposition
der beiden Teile 4,5 fixiert wird.For such a tensioning device is now, also by reference
to the Fig.1,2 essential that the two the
Wie aus den Darstellungen ersichtlich, ist die Verzahnung 9 am
spannarmseitigen Teil 5 vorteilhaft nur an dessen unteren Endbereich
10 angeordnet, um wie einleitend vorerwähnt und unter
Verweis auf Fig.4 das Ausschwenkerfordernis des Teiles 5 für
eine Entrastung so klein wie möglich zu halten. Die Schwenkbarkeit
des Teiles 5 ist dabei per se gegeben, da dieses durch
ein Gelenk 20 mit einem Zwischen- bzw. Schleppglied 21 der
Stellmechanik 2 verbunden ist, das seinerseits gelenkig mit
einem Stellhebel 22 der Schwenkwelle 23 des Spannarmes 1 in
Verbindung steht, worauf nur der Vollständigkeit halber
hingewiesen sei. As can be seen from the illustrations, the
Die der Fixierung der beiden Teile 4,5 in jeweiliger Verrastungsposition
dienende Querverschraubung 13 ist aus einer in
die Verschraubungsbohrung 11 eingeführten und den Durchgriffsschlitz
12 durchgreifenden Kopfschraube 14 gebildet, an deren
aus dem Schlitz 12 herausragendem Ende eine Mutter 15 angeordnet
und diese verdrehgesichert im Kopfstück 3 der Vorrichtung
geführt ist.The fixation of the two
Da, wie vorerwähnt, zwecks Öffnungswinkelveränderung bzw. Öffnungswinkeleinstellung
eine Entfernung der Querverschraubung 13
nicht erforderlich ist, besteht eine vorteilhafte Weiterbildung
unter Verweis auf Fig.5 darin, daß am Ende der Kopfschraube 14
vor oder in der aufgeschraubten Mutter 15 ein Sicherungselement
16, wie Sicherungsring od.dgl., angeordnet ist. Dieses Sicherungselement
16 sorgt dabei vorteilhaft dafür, daß beim Ausdrehen
der Kopfschraube 14 aus der Mutter 15 die Schraube nicht
vollständig aus der Mutter herausgeschraubt werden kann, d.h.,
die ganze Querverschraubung verbleibt trotz Lösung unverlierbar
an der Vorrichtung.Since, as mentioned above, for the purpose of opening angle change or opening angle adjustment
a distance of the
Um den Eingriff der Zähne 9' bei gewünschter Positionierung der
Teile 4,5 nicht durch scharfkantige Zähne zu behindern, sind
diese vorteilhaft mit abgerundeten oder angephasten Kanten 9"

Parts 4.5 are not hampered by sharp-edged teeth are
these beneficial with rounded or
Um die Verstellung von einem großen Öffnungswinkel des Spannarmes
1 auf einen kleineren nochmals am konkreten Ausführungsbeispiel
zu erläutern, wird auf die Fig. 2, 3 und 4 verwiesen.
Will man den großen Öffnungswinkel des Spannarmes 1 gemäß Fig.3
verkleinern, so wird die Querverschraubung 13 gelöst, wodurch
die beiden Teile 4,5 bzw. deren Verzahnung 9 entrastet werden
können, wie dies aus Fig.4 ersichtlich ist. Durch die Entrastung
ist aber nun der Weg frei, das Teil 5 durch Verschwenken
des Spannarmes 1 gemäß Fig.3 im Gegenuhrzeigersinn um
das gewünschte Maß anzuheben und dessen im unteren Endbereich
10 angeordneten Zähne in die stehengebliebene Verzahnung 9 des
anderen Teiles 4 einzurasten und das Ganze in der neuen Position
mit der Querverschraubung 13 zu fixieren, die dann einem
kleineren Öffnungswinkel bspw. gemäß Fig.2 entspricht. Für die
Umstellung von einem kleinen Öffnungswinkel auf einen größeren
geschieht umgekehrt praktisch das Gleiche, nur mit dem Unterschied,
daß hierbei der Spannarm im Uhrzeigersinn zu drehen und
damit das Teil 5 abzusenken ist.To the adjustment of a large opening angle of the
