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 Benutzung, so daß es keines besonderen druckschriftlichen Nachweises bedarf. Derartige Spannvorrichtungen werden benötigt, um irgendwelche Werkstücke zu Bearbeitungszwecken auf Tischen von Bearbeitungsmaschinen 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 Kolhenstange gilt das gleiche, d.h. diese Sensoren sind entweder am Kopfstück der Vorrichtung oder im Bereich des Betätigungszylinders 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 Beschädigungsfall zu Funktionsstörungen der Endabfragung führen kann. Je nach den örtlichen Einbau- und Anordnungsverhältnissen der Spannvorrichtung kann es also wünschenswert 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 in order to be able to weld them precisely. 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 and the other side 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 on both sides to the flanges forming the cylinder ends, ie in particular the return 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 button switch) for the end position query of the piston rod, the same applies, i.e. these sensors are located either on the head 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 generally 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 the event of damage can lead to malfunction of the final detection. Depending on the local installation and arrangement conditions of the tensioning device, it may be desirable to be able to assign the cable connector 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, dar das Kabelanschlußstück 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 in the introduction and so that the cable connector and thus also 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 tensioning 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 voll den Sensoren zum Kabelanschlußstück führenden Leitungen und das Anschlußstück selbst entweder seitlich oder nach hinten abgehend am Zylinder anzuordnen, 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. Der Kanal ist 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 erfindungs gemäßen 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 therefore both the manufacturer of such devices, but also the user, depending on the installation conditions of the overall device, to arrange the lines leading fully to the sensors for the cable connector and the connector itself, either laterally or rearwards, on the cylinder, where 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 at the side or at the rear of the mouths of the branches. The channel is formed with its two branches as a groove open to the outside, 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 fiction, contemporary design of the channel in the form of a groove open to the outside, a change of one or the other arrangement direction of the cable connector is particularly easy, since after removing the cover, the entire channel with its branches remains open and thus a change in the wiring is easily 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.Apart from 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 connector 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.

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 sein. 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 je nach den Anschlußgegebenheiten angeordnet werden kann. Der Kanales 2 mit seinen Zweigen 4, 5 ist nicht als Bohrung ausgebildet, sondern 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, dar 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 exemplary embodiment shown is a special type of tensioning device in which the two sensors, which are arranged at selectable distances from one another, are actuated with an adjusting 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 can be 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, do not require any further explanation here, since in the present case only the arrangement of the cable connection piece 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 can be arranged at the end of the side branch 4 or at the end of the other branch 5 depending on the connection conditions. The channel 2 with its branches 4, 5 is not designed as a bore, but 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 form shown, for example, which has an angled flag 9 to which the cable connector 7 is fastened 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, is only fixed with a small screw at the point 10 of the end flange 3'. The arrangement of this point 10 is made so 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 design 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 connecting piece 7 is disruptive or if there is a particular risk of damage there, and the arrangement of the cable connecting piece 7 goes backwards, as in FIG. 1 shown in dash-dotted lines, is desired, so 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 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.This problem-free changeover option also has the essential advantage of designing the channel in the form of a groove that, in the event of an exchange requirement, the entire sensor device, i. 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.
