Description

Die Erfindung betrifft eine Spannvorrichtung, insbesondere Knie­hebelspannvorrichtung zum Festspannen von Werkstücken gemäß Oberbegriff des Hauptanspruches.The invention relates to a clamping device, in particular toggle lever clamping device for clamping workpieces according to the preamble of the main claim.

Spannvorrichtungen der genannten Art sind hinlänglich bekannt und in Benutiung, so daß es keines besonderen druckschriftlichen Nachweises bedarf. Derartige Spannvorrichtungen werden benötigt, um irgendwelche Werkstücke zu Bearbeitungszwecken auf Tischen von Bearbeitugnsmaschinen festzuspannen, insbesondere aber auch, um bspw. Karrosserieteile u.dgl. Bleche zueinander zu fixieren, um sie lagegenau verschweißen zu können. Die Betätigung der Spannarme an diesen Vorrichtungen erfolgt in der Regel mit Betä­tigungszylindern, deren Kolben pneumatisch von der einen und der anderen Seite mit Druck beaufschlagbar sind, um den Spannarm ei­nerseits in Schließstellung und andererseits wieder in Öffnungs­stellung zu bringen. Die Druckmediumsanschlüsse sind beidseitig an den die Zylinderenden bildenden Flanschen angesetzt, d.h. insbesondere die Rückstell-Druckmediumsleitung erstreckt sich seitlich über die ganze Länge des Stellzylinders. Je nach Art der verwendeten Sensoren (Magnetfeldschalter, Näherungsschalter oder Rollentastschalter) für die Endstellungs-Abfrage der Kol­benstange gilt das gleiche, d.h. diese Sensoren sid entweder am Kopfstück der Vorrichtung oder im Bereich des Betätiungszylin­ders seitlich angeordnet, wobei sich die Leitungsführungen eben­falls seitlich an den Vorrichtungen erstrecken und das Kabelan­schlußstück ebenfalls quer zur Längsachse der Vorrichtung abste­hend angeordnet ist. In Rücksicht auf die in der Regel gegebenen engen Raumverhältnisse kann eine derartige seitliche Anordnung des Anschlußstückes hinderlich sein, zumal damit die Beschädi­gungsgefahr stromführender Kabel erhöht wird, was im Beschädi­ gungsfall zu Funktionsstörungen der Endabfragung führen kann. Je nach den örtlichen Einbau- und Anordnungsverhältnissen der Spannvorrichtung kann es also wünschensert sein, das Kabelan­schlußstück derart der Vorrichtung zuordnen zu können, daß es entweder seitlich oder axial nach hinten am Betätigungszylinder abgeht.Clamping devices of the type mentioned are well known and in use, so that no special printed evidence is required. Clamping devices of this type are required in order to clamp any workpieces for machining purposes on tables of processing machines, but in particular also to, for example, body parts and the like. Fix the sheets to each other so that they can be welded in the correct position. The actuation of the clamping arms on these devices is usually carried out with actuating cylinders, the pistons of which can be pressurized pneumatically from one side and the other in order to bring the clamping arm into the closed position on the one hand and again into the open position on the other hand. The pressure medium connections are attached to the flanges forming the cylinder ends on both sides, ie in particular the reset pressure medium line extends laterally over the entire length of the actuating cylinder. Depending on the type of sensors used (magnetic field switch, proximity switch or roller switch) for the end position query of the piston rod, the same applies, i.e. these sensors are located either on the head piece of the device or in the area of the actuating cylinder, with the cable routing also on the side of the devices extend and the cable connector is also arranged transversely to the longitudinal axis of the device. In view of the usually narrow space conditions, such a lateral arrangement of the connector can be a hindrance, especially since the risk of damage to current-carrying cables is increased, which in damage case can lead to malfunctions in the end detection. Depending on the local installation and arrangement conditions of the tensioning device, it may be desirable to be able to assign the cable connection piece to the device in such a way that it goes off either laterally or axially to the rear of the actuating cylinder.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, Spannvorrich­tungen der eingangs genannten Art dahingehend zu verbessern und so auszubilden, daß das Kabelanschlußstücke und damit auch die zu diesem führenden Leitungen auch nach hinten abgehend angeordnet werden können.The invention is therefore based on the object to improve tensioning devices of the type mentioned and to design so that the cable connectors and thus the leads leading to this can also be arranged outgoing to the rear.

Diese Aufgabe ist mit einer Spannvorrichtung der eingangs ge­nannten Art nach der Erfindung durch die im Kennzeichen des Hauptanspruches geführten Merkmale gelöst. Vorteilhafte Weiter­bildungen ergeben sich nach den Unteransprüchen.This object is achieved with a clamping device of the type mentioned according to the invention by the features listed in the characterizing part of the main claim. Advantageous further developments result from the subclaims.

Bei dieser erfindungsgemäßen Ausbildung hat es also sowohl der Hersteller derartiger Vorrichtungen, aber auch der Benutzer in der Hand, je nach den Einbauverhältnissen der Gesamtvorrichtung die von den Sensoren zum Kabelanschlußstück führenden Leitungen und das Anschlußstück selbst entweder seitlich oder nach hinten abgehend am Zylinder anzuodnen, wobei lediglich die Leitungen durch den einen oder anderen Zweig des Unterbringungskanales zu führen sind und das Kabelanschlußstück entweder seitlich oder hinten an den Ausmündungen der Zweige anzuordnen. Zweckmäßig wird dabei der Kanal mit seinen beiden Zweigen als nach außen offene Nut ausgebildet, wobei die Abdeckung einerseits als Trä­ger für das Kabelanschlußstück und andererseits als Verschluß für die Nut dient. Bei dieser vorteilhaften Ausbildung des Kana­les in Form einer nach außen offenen Nut ist ein Wechsel der einen oder anderen Anordnungsrichtung des Kabelanschlußstückes besonders einfach, da nach Abnahme der Abdeckung der gesamte Ka­nal mit seinen Zweigen offen bleibt und somit einer Umstellung der Leitungsführung ohne weiteres zugänglich ist. Abgesehen von dieser Wechselmöglichkeit hat dies aber auch den Vorteil, daß die gesamte Sensoranordnung einschließlich der Leitungen mit ih­rem Kabelanschlußstück denkbar einfach ausgetauscht werden kann, zumal die Sensoren, die Leitungsstücke und das Kabelanschluß­stück in der Regel nicht steckverbunden, sondern fest miteinan­der verbunden sind.In this embodiment of the invention, it is both the manufacturer of such devices, but also the user, depending on the installation conditions of the overall device, the leads leading from the sensors to the cable connector and the connector itself either on the side or rearwards on the cylinder, whereby only the lines are to be led through one or the other branch of the accommodation channel and the cable connector is to be arranged either laterally or at the rear of the mouths of the branches. The channel with its two branches is expediently designed as an open groove, the cover serving on the one hand as a carrier for the cable connector and on the other hand as a closure for the groove. In this advantageous embodiment of the channel in the form of a groove that is open to the outside, changing one or the other arrangement direction of the cable connection piece is particularly simple, since after removing the cover the entire channel with its branches remains open and thus a change in the line routing is readily accessible. Apart from this change option, this also has the advantage that the entire sensor arrangement including the lines with their cable connection piece can be exchanged very easily, especially since the sensors, the line pieces and the cable connection piece are generally not plug-in, but are firmly connected to one another.

Abgesehen davon, daß diese gesamte Sensoreinrichtung je nach den konstruktiven Gegebenheiten sowohl im Kopfstück als auch im Be­reich des Betätigungszylinders angeordnet sein kann, wird vor­zugsweise der Kanal bzw. die mit seinen/ihren beiden Zweigen im Endflansch des Betätigungszylinder angeordnet.In addition to the fact that this entire sensor device can be arranged both in the head piece and in the area of the actuating cylinder, depending on the structural conditions, the channel or its two branches are preferably arranged in the end flange of the actuating cylinder.

Die vorerwähnte Abdeckung besteht vorteilhaft aus einem einfa­chen Blechzuschnitt mit einer abgewinkelten Fahne, an der das Kabelanschlußstück angeordnet ist. Die Abdeckung ist dabei fer­ner vorteilhaft derart ausgebildet, daß sie in beiden Stellungen an der gleichen Stelle der Vorrichtung befestigt werden kann.The aforementioned cover advantageously consists of a simple sheet metal blank with an angled flag on which the cable connection piece is arranged. The cover is also advantageously designed such that it can be attached in both positions at the same location on the device.

Die erfindungsgemäße Spannvorrichtung wird nachfolgend anhand der zeichnerischen Darstellung eines Ausführungsbeispieles näher erläutert.The tensioning device according to the invention is explained in more detail below with reference to the drawing of an exemplary embodiment.

Es zeigt schematisch

  • Fig. 1 teilweise in Schnitt und Ansicht eine Spannvorrich­tung und
  • Fig. 2 die Spannvorrichtung gemäß Fig. 1 in Ansicht vom freien Ende des Betätigungszylinders her gesehen.
It shows schematically
  • Fig. 1 partially in section and view of a clamping device and
  • Fig. 2 seen the tensioning device according to FIG. 1 in view from the free end of the actuating cylinder.

Beim dargestellten Ausführungsbeispiel handelt es sich um eine Spannvorrichtung besonderer Art, bei der die beiden in wählbaren Abständen zueinander angeordneten Sensoren mit einer Stellstange betätigt werden, die - wie ersichtlich - am oberen Ende der Kol­benstange 12 in geeigneter Weise befestigt ist. Unabhängig von diesem speziellen Ausführungsbeispiel könnten die beiden Senso­ren 11, was ebenfalls bekannt ist, auch unmittelbar im Bereich der Kolbenstange am Kopfstück 13 der Spannvorrichtung angeordnet ein. Diese speziellen Ausführungsmöglichkeiten derartiger Spannvorrichtungen einschließlich der speziellen Anordnung der Sensoren 11 bedarf hier keiner näheren Erläuterung, da im vor­liegenden Fall nur die Anordnung des Kabelanschlußstückes 7 mit den zu den Sensoren 11 führenden Anschlußleitungen von Belang ist. Wie aus Fig. 1 ersichtlich, sind die Anschlußleitungen 1 in einem Kanal 2 der Spannvorrichtung angeordnet, der einen seit­lich abgehenden Zweig 4 und einen zum freien Ende 3 der Vorrich­tung führenden zweig 5 aufweist. Das Kabelanschlußstück 7 sitzt dabei an einer Abdeckung 6, die mit dem Kabelanschlußstück 7 derart umstellbar an der Vorrichtung sitzt, daß das Kabelan­schlußstück 7 am Ende des seitlichen Zweiges 4 oder am Ende des anderen Zweiges 5 des Kanales 2 mit seinen Zweigen 4, 5 nicht als Bohrung ausgebildet, sondern vorteilhaft in Form einer nach außen offenen Nut 2′, die lediglich von der Abdeckung 6 abge­deckt wird. Diese Abdeckung 6 ist aus einem Blechzuschnitt 6′ in der bspw. dargestellten Form gebildet, der eine abgewinkelte Fahne 9 aufweist, an der das Kabelanschlußstück 7 in geeigneter Weise befestigt und wie ersichtlich angeordnet ist. Beim gezeig­ten Ausführungsbeispiel ist dieser Blechzuschnitt an die Form des Endflansches 3′ des Betätigungszylinders 8 angepaßt und, wie ebenfalls ersichtlich, lediglich mit einer kleinen Schraube an der Stelle 10 des Endflansches 3′ fixiert. Die Anordnung dieser Stelle 10 ist dabei so getroffen, daß der Blechzuschnitt 6′ auch in der strichpunktierten Stellung fixiert werden kann, bei der das Kabelanschlußstück 7 nach hinten vom Endflansch 3′ des Betä­tigungszylinders 8 abgeht. Eine derartige Kanal- bzw. Nutausbil­dung und Anordnung könnte natürlich auch - soweit dies die kon­struktiven Verhältnisse zulassen - ebenfalls am zylinderseitigen Ende des Kopfstückes vorgesehen werden.The illustrated embodiment is a clamping device of a special type, in which the two sensors, which are arranged at selectable distances from one another, are actuated with an actuating rod which, as can be seen, is fastened in a suitable manner to the upper end of the piston rod 12. Regardless of this special embodiment, the two sensors 11, which is also known, could also be directly in the area the piston rod is arranged on the head piece 13 of the tensioning device. These special design options of such tensioning devices, including the special arrangement of the sensors 11, require no further explanation here, since in the present case only the arrangement of the cable connector 7 with the connecting lines leading to the sensors 11 is relevant. As can be seen from FIG. 1, the connecting lines 1 are arranged in a channel 2 of the tensioning device, which has a branch 4 going out laterally and a branch 5 leading to the free end 3 of the device. The cable connector 7 sits on a cover 6, which is so convertible with the cable connector 7 on the device that the cable connector 7 at the end of the side branch 4 or at the end of the other branch 5 of the channel 2 with its branches 4, 5 not as Bore formed, but advantageously in the form of an outwardly open groove 2 ', which is only covered by the cover 6. This cover 6 is formed from a sheet metal blank 6 'in the example shown, which has an angled flag 9, to which the cable connector 7 is attached in a suitable manner and is arranged as can be seen. In the embodiment shown, this sheet metal blank is adapted to the shape of the end flange 3 'of the actuating cylinder 8 and, as can also be seen, only fixed with a small screw at the point 10 of the end flange 3'. The arrangement of this point 10 is such that the sheet metal blank 6 'can also be fixed in the dot-dash position in which the cable connector 7 goes backwards from the end flange 3' of the actuating cylinder 8. Such a channel or groove formation and arrangement could, of course, also be provided at the cylinder-side end of the head piece, insofar as the structural conditions permit.

Falls je nach den Anbringungserfordernissen der Spannvorrichtung an der Betriebsstelle die seitliche Anordnung des Kabelanschluß­stückes 7 stören oder dieses dort in besonderem Maße einer Be­schädigungsgefahr ausgesetzt sein sollte und die Anordnung des Kabelanschlußstückes 7 nach hinten abgehend, wie in Fig. 1 strichpunktiert dargestellt, gewünscht ist, so ist lediglich die Abdeckung 6 bzw. der Blechzuschnitt 6′ an der Stelle 10 zu lösen und das Ganze entsprechend umzusetzen, wobei dann die von vorn­herein entsprechend lang gehaltenen Anschlußleitungen 1 in den Zweig 5 eingelegt werden und die Abdeckung 6 wieder am End­flansch 3′ an der Stelle 10 fixiert werden muß. Für den umge­kehrten Fall gilt dabei natürlich das Gleiche.If, depending on the attachment requirements of the tensioning device at the operating point, the lateral arrangement of the cable connection piece 7 is disruptive or if there is a particular risk of damage there, and the arrangement of the cable connection piece 7 goes backwards, as in FIG. 1 shown in dash-dotted lines, is desired, only the cover 6 or the sheet metal blank 6 'to be loosened at point 10 and implement the whole accordingly, in which case the correspondingly long connecting lines 1 are inserted into the branch 5 and the cover 6 again at the end flange 3 'at point 10 must be fixed. In the opposite case, of course, the same applies.

Diese problemlose Umstellungsmöglichkeit hat bei der bevorzugten Ausbildung des Kanales in Form einer Nut auch noch den wesentli­chen Vorteil, daß im Falle eines Austauscherfordernisses die ganze Sensoreinrichtung, d.h. die Sensoren 11, die Anschlußlei­tungen 1 und das Kabelanschlußstück 7 denkbar leicht ausgewech­selt werden können, und zwar völlig unabhängig davon, ob nun das Kabelanschlußstück 7 zur Seite oder nach hinten am Betätigungs­zylinder bzw. an dessen Endflansch 3′ angesetzt ist.In the preferred embodiment of the channel in the form of a groove, this problem-free changeover option also has the essential advantage that, in the event of an exchange requirement, the entire sensor device, i.e. the sensors 11, the connecting lines 1 and the cable connector 7 can be easily replaced, regardless of whether the cable connector 7 to the side or to the rear of the actuating cylinder or at its end flange 3 'is attached.
