Description

Die Erfindung betrifft eine elektrisch betätigbare Werkstück-Spannvorrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an electrically actuated workpiece clamping device according to the preamble of claim 1.

Eine derartige Spannvorrichtung ist beispielsweise nach der DE 36 38 526 C1 bekannt. Mit der axialen Zuordnung von Elektroantrieben zum Spannkopf sollen die bislang weitaus häufiger benutzten Pneumatik- oder Hydraulikantriebe in Form von Betätigungszylindern ersetzt werden. Problematisch ist dabei die Krafteinbringung, die bei Elektroantrieben auf Kosten der Baubreite solcher Spannvorrichtungen geht, da sich ein höheres Leistungsvermögen des Elektroantriebes im Durchmesser des Elektromotors niederschlägt, der dann zwangsläufig größer ist als die Baubreite des Spannkopfes. Mit Rücksicht auf die Verwendung solcher Spannvorrichtungen beispielsweise im Karosseriebau wird jedoch grundsätzlich eine möglichst schmale Baubreite angestrebt, die jedoch bei verlangter hoher Krafteinbringung nicht einzuhalten ist.Such a tensioning device is, for example, according to DE 36 38 526 C1 known. With the axial assignment of electric drives to the clamping head are said to be used far more often so far Pneumatic or hydraulic drives in the form of actuating cylinders be replaced. The problem is that Force input in the case of electric drives at the expense of the overall width such jigs goes because there is a higher one Performance of the electric drive in the diameter of the Electric motor precipitates, which is then necessarily larger than the width of the clamping head. Regarding the use such jigs, for example, in the body shop However, the width is generally as narrow as possible strived for, but with the required high force input is not to be observed.

Ausgehend von einer Spannvorrichtung der gattungsgemäßen Art, liegt der Neuerung die Aufgabe zugrunde, eine solche Spannvorrichtung hinsichtlich ihres Antriebes dahingehend auszubilden und zu verbessern, daß dieser trotz hohem Leistungsvermögens nur eine vergleichsweise schmalen Baubreite verlangt.Starting from a tensioning device of the generic type, the innovation is based on the task of such a clamping device to train with regard to their drive and improve that despite high performance only requires a comparatively narrow overall width.

Diese Aufgabe ist mit einer Spannvorrichtung der eingangs geannten Art nach der Erfindung durch die im Kennzeichen des Anspruchs 1 genannten Merkmale gelöst.This task is with a jig the beginning said type according to the invention by the in the characteristics of Features mentioned claim 1 solved.

Mit dieser erfindungsgemäßen Ausbildung ist die gestellte Forderung erfüllt. Die Alternativangabe "direkt oder indirekt in Wirkverbindung stehend" wird noch näher erläutert. With this training according to the invention, the requirement is Fulfills. The alternative specification "directly or indirectly in Active connection "is explained in more detail.

Vorteilhafte Weiterbildungen bestehen in Folgendem:Advantageous further training consists of the following:

Der Abstand der Seitenwände des die beiden Motoren aufnehmenden Gehäuses zueinander ist gleich oder im wesentlichen gleich der Breite des auf dem Gehäuse aufgesattelten Spannkopfes, was nichts anderes bedeutet, als daß die vom jeweiligen Spannkopf her vorgegebene Breite für das Motorengehäuse voll ausgenutzt wird.The distance between the side walls of the two engines Housing to each other is the same or substantially the same Width of the clamping head saddled on the housing, what nothing other than that of the respective clamping head The specified width for the motor housing is fully utilized becomes.

Die Einrichtungen zur Wandlung der Drehbewegung in eine translatorische Bewegung sind aus folgenden Elementen gebildet:The devices for converting the rotary movement into a translatory Movements are made up of the following elements:

Zwischen den Motoren ist eine drehbar gelagerte, mit einem Zahnrad versehene Hohlwelle angeordnet, in die die Gewindespindel bei Rückstellung bzw. Öffnung der Spannvorrichtung eintauchen kann.Between the motors is a rotatably mounted one Geared hollow shaft arranged, in which the threaded spindle when the tensioning device is reset or opened can immerse.

Auf den Abtriebswellen der beiden Motoren sind mit dem Zahnrad der Hohlwelle im Eingriff stehende Antriebsritzel angeordnet und zwischen der Hohlwelle und der Gewindespindel ist ein mit der Hohlwelle drehbares und mit der Gewindespindel im Eingriff stehendes Übertragungselement angeordnet, das bevorzugt in Form einer Kugelumlaufmutter ausgebildet ist.On the output shafts of the two motors are with the gear arranged in the hollow shaft engaging drive pinion and between the hollow shaft and the threaded spindle is a the hollow shaft rotatable and in engagement with the threaded spindle standing transmission element arranged, preferably in the form a ball nut is formed.

Diese im wesentlichen bekannten Einrichtungsbauteile schaffen in Verbindung mit dem erfindungsgemäßen Einbau zweier Motoren für dem Antrieb der Spannvorrichtung die Voraussetzung für eine möglichst kompakte Bauweise und auch zweckmäßige Montagehandhabung des Antriebes, und zwar nicht nur hinsichtlich eines möglichst geringen Abstandes der Seitenwände des Gehäuse, sondern auch hinsichtlich möglichst geringer Abmessungen in Erstreckungsrichtung des Spannarmes der Spannvorrichtung. So ist das vorerwähnte Übertragungselement in einer topfartigen Erweiterung am oberen Ende der Hohlwelle angeordnet. Das Zahnrad und die mit diesem im Eingriff stehenden Antriebsritzel sind am unteren Endbereich der Hohlwelle angeordnet, wobei in Verbindung damit der untere, den spannarmfernen Endbereich der Hohlwelle, das Zahnrad und die Antriebsritzel aufnehmende Teil des Gehäuses diesem als lösbares Gehäuseteil zugeordnet ist. Damit ist nicht nur eine günstige Montage geschaffen, sondern dieser Teil des Antriebes ist auch bequem von unten her im Bedarfsfall zugänglich.Create these essentially known furnishing components in connection with the installation of two motors according to the invention for the drive of the clamping device the prerequisite for one The most compact possible construction and also convenient assembly handling of the drive, and not only with regard to one the smallest possible distance between the side walls of the housing, but also with regard to the smallest possible dimensions in the direction of extension of the clamping arm of the clamping device. So is the aforementioned transmission element in a pot-like extension arranged at the upper end of the hollow shaft. The gear and the drive pinion engaged with this are on arranged lower end region of the hollow shaft, being in connection so that the lower end of the hollow shaft, which is far from the tension arm, the gear and the pinion receiving part of the Housing this is assigned as a detachable housing part. In order to not only is an inexpensive installation created, but this one Part of the drive is also convenient from below when needed accessible.

Eine weitere vorteilhafte Ausbildung besteht darin, daß das untere Ende der Hohlwelle den Boden des Gehäuses mindestens bündig mit diesem abschließend durchgreift und mit einem Fremdantriebs-Anschlußelement versehen ist. Dadurch bleibt die Spannvorrichtung auch bei Stromausfall oder Motorschaden betätigbar.Another advantageous training is that lower end of the hollow shaft at least the bottom of the housing engages flush with this and with one External drive connection element is provided. This leaves the Clamping device can also be operated in the event of a power failure or engine damage.

Die erfindungsgemäße Spannvorrichtung und weitere vorteilhafte Ausführungsformen werden nachfolgend anhand der zeichnerischen Darstellung eines Ausführungsbeispieles näher erläutert.The tensioning device according to the invention and other advantageous Embodiments are described below with reference to the drawings Representation of an embodiment explained in more detail.

Die elektrisch betätigbare Spannvorrichtung besteht aus einem an einem Spannkopf 1 angeordneten Elektroantrieb 2 zur Betätigung einer Gewindespindel 3, die mit der im Spannkopf 1 angeordneten Stellmechanik SM für den Spannarm 4 in Wirkverbindung steht. Der Spannkopf 1 mit seiner Stellmechanik SM und dessen Funktion bedarf dabei keine besonderen Erläuterung, da hinlänglich bekannt, ganz abgesehen davon, daß sich ein solcher Spannkopf bzw. eine solche Spannvorrichtung auch ohne weiteres mit einem pneumatischen oder hydraulischen Betätigungszylinder betreiben ließe, wobei lediglich die Gewindespindel 3 durch die Schubstange des jeweiligen Betätigungszylinders ersetzt würde.The electrically operated clamping device consists of a arranged on a clamping head 1 electric drive 2 for actuation a threaded spindle 3, which is arranged in the clamping head 1 Actuating mechanism SM for the tension arm 4 in operative connection stands. The clamping head 1 with its adjusting mechanism SM and its function does not require any special explanation, since well known, quite apart from the fact that such Clamping head or such a clamping device without further ado with a pneumatic or hydraulic actuating cylinder operate, only the threaded spindle 3 through the Push rod of the respective actuating cylinder would be replaced.

Für die erfindungsgemäße Spannvorrichtung ist nun unter Verweis auf die Fig. 1 und 3 wesentlich, daß der in einem Gehäuse 5 angeordnete Elektroantrieb 2 aus zwei sich in ihrer Leistung addierenden, synchron geschalteten Motoren 6 gebildet ist, die mechanisch mit Einrichtungen 7 zur Wandlung ihrer Drehbewegung in eine translatorische Bewegung des mit der Gewindespindel 3 in Verbindung stehenden ersten Gliedes der Stellmechanik SM gekoppelt sind. Die Achsen 8 der Motoren 6 und die sich mittig zwischen deren Achsen 8 erstreckende Achse 9 der Gewindespindel 3 stehen senkrecht auf einer gedachten Geraden 10 (siehe Fig. 3) und die sich zur Geraden 10 parallel erstreckenden Seitenwände 11 des Gehäuses 5 sind mit einem Abstand A zueinander distanziert, der geringfügig größer (um die doppelte Wandstärke des Gehäuses 5) ist als der Durchmesser D der Motoren 6, für die im übrigen aus Kostengründen vorteilhaft handelserhältliche Großserien-Motoren zur Verwendung kommen.For the tensioning device according to the invention is now by reference 1 and 3 essential that the in a housing 5th arranged electric drive 2 out of two in their performance adding, synchronously connected motors 6 is formed, the mechanically with devices 7 for converting their rotary movement in a translational movement of the threaded spindle 3 related first link of the actuating mechanism SM are coupled. The axes 8 of the motors 6 and the center between the axes 8 extending axis 9 of the threaded spindle 3 are perpendicular to an imaginary straight line 10 (see Fig. 3) and the side walls extending parallel to the straight line 10 11 of the housing 5 are at a distance A from each other distanced, which is slightly larger (by twice the wall thickness of the housing 5) is the diameter D of the motors 6, for which is otherwise commercially available for reasons of cost Large series engines are used.

Unter Verweis auf Fig. 2 ist dieser Abstand A derart bemessen, daß dieser vorzugsweise gleich oder im wesentlichen gleich der Breite B des auf dem Gehäuse 5 aufgesattelten Spannkopfes 1 ist.With reference to FIG. 2, this distance A is dimensioned such that that this is preferably the same or substantially the same Width B of the clamping head 1 saddled on the housing 5 is.

Die Einrichtungen 7 zur Wandlung der Drehbewegung in eine translatorische Bewegung bestehen im Einzelnen aus einer zwischen den Motoren 6 drehbar gelagerten, mit einem Zahnrad 12 versehenen Hohlwelle 13, in die die Gewindespindel 3 bei Axialverstellung eintaucht. Auf den Abtriebswellen 14 der beiden Motoren 6 sind mit dem Zahnrad 12 der Hohlwelle 13 im Eingriff stehende Antriebsritzel 15 angeordnet, deren Drehung damit der Hohlwelle 13 entsprechend übersetzt vermittelt und deren Drehung wiederum per vorzugsweise als Kugelumlaufmutter ausgebildetem Übertragungselement 16 als translatorische Verstellbewegung der Gewindespindel 3 übertragen wird.The devices 7 for converting the rotary movement into a Translational movement consists in particular of an between the motors 6 rotatably mounted with a gear 12 provided hollow shaft 13, in which the threaded spindle 3 at Immersed axial adjustment. On the output shafts 14 of the two Motors 6 are with the gear 12 of the hollow shaft 13 in Engaged drive pinion 15 arranged, the rotation thereof so that the hollow shaft 13 is translated accordingly whose rotation in turn preferably as a recirculating ball nut trained transmission element 16 as a translational adjustment movement the threaded spindle 3 is transmitted.

Dieses Übertragungselement 16 bzw. diese Kugelumlaufmutter ist, wie aus Fig. 1 ersichtlich, fest in einer topfartigen Erweiterung 17 am oberen Ende der Hohlwelle 13 untergebracht, welche Erweiterung 17 gleichzeitig und wie angedeutet zur Axial- und Radiallagerung der Hohlwelle 13 an deren oberen Endbereich mit ausgenutzt ist. Bei dieser Ausführungsform gemäß Fig. 1 steht also die nicht drehende Gewindespindel 3 in direkter Verbindung mit dem ersten Glied der Stellmechanik.This transmission element 16 or this ball nut is 1, fixed in a pot-like extension 17 housed at the upper end of the hollow shaft 13, which Extension 17 at the same time and as indicated for the axial and Radial bearing of the hollow shaft 13 at its upper end region is exploited. In this embodiment according to FIG. 1 stands So the non-rotating threaded spindle 3 in direct connection with the first link of the actuating mechanism.

Möglich ist aber auch, was nicht besonders dargestellt ist, da ohne weiteres vorstellbar, eine kinematische Umkehrung dahingehend, daß die Hohlwelle 13 mit der Stellmechanik SM verbunden ist. Die Erweiterung 17 ist dabei nach unten gerichtet und die dann von den Zahnrädern 12, 15 angetriebene Gewindespinel 3 greift von unten her in die Hohlwelle 13 ein. Statt des die Erweiterung 17 umfassenden Nadellagers in Fig.1 muß dann für eine verdrehfeste, aber eine Axialverschiebung zulassende Halterung der Hohlwelle 13 gesorgt werden, d.h., bei einer solchen Ausführungsform steht die Gewindespindel 3 mit der Stellmechanik via Hohlwelle 13 in indirekter Wirkverbindung. Bevorzugt wird jedoch die in Fig. 1 dargestellte Ausführungsform, da diese mit geringerem Aufwand verbunden ist.But what is not particularly depicted is also possible easily imaginable, a kinematic reversal in that that the hollow shaft 13 is connected to the actuating mechanism SM is. The extension 17 is directed downwards and the then threaded spindle 3 driven by the gear wheels 12, 15 engages the hollow shaft 13 from below. Instead of the Extension 17 comprehensive needle bearing in Fig.1 must then for a torsion-proof, but allowing axial displacement the hollow shaft 13 can be taken care of, i.e., in such a case Embodiment stands the threaded spindle 3 with the actuating mechanism via hollow shaft 13 in indirect operative connection. Prefers However, the embodiment shown in Fig. 1, because this is associated with less effort.

Das Zahnrad 12 und die mit diesem im Eingriff stehenden Antriebsritzel 15 der beiden Motoren 6 sind vorteilhaft und leicht zugriffszugänglich am unteren Endbereich der Hohlwelle 13, wie in Fig. 1 dargestellt, plaziert, wobei der untere, den unteren Endbereich der Hohlwelle 13, das Zahnrad 12 und die Antriebsritzel 15 aufnehmende Teil des Gehäuses 5 diesem als lösbares Gehäuseteil 5' zugeordnet ist.The gear 12 and the drive pinion meshing with it 15 of the two motors 6 are advantageous and easily accessible at the lower end of the hollow shaft 13, as shown in Fig. 1, the lower, the lower end portion of the hollow shaft 13, the gear 12 and the Drive pinion 15 receiving part of the housing 5 as this releasable housing part 5 'is assigned.

Ebenfalls mit in Fig. 1 dargestellt ist die vorteilhafte Maßgabe, daß das untere Ende 18 der Hohlwelle 13 den Boden 19 des Gehäuses 5 durchgreift und mit einem Fremdantriebs-Anschlußelement 20 versehen ist. In der dargestellten Ausführungsform handelt es sich bei diesem Element beispielsweise einfach um ein Mehrkantsackloch, in das ein entsprechender beispielsweise Innensechskantschlüssel eingesteckt wird, um damit bei Ausfall des motorischen Antriebes per Hand eine Verstellung der Spannvorrichtung vornehmen zu können.Also shown in FIG. 1 is the advantageous requirement that the lower end 18 of the hollow shaft 13 the bottom 19 of the Passes through housing 5 and with an external drive connection element 20 is provided. In the illustrated embodiment for example, this element is simply a polygonal pocket hole into which a corresponding one, for example Allen key is inserted to avoid failure the motorized drive is adjusted manually to be able to make.

An der rückwärtigen Schmalsseite 21 des Gehäuses 5 ist ein Steuerelektronikgehäuse 22 angebracht, das mit im Spannkopf 1 in herkömmlicher Weise angeordneten Endstellungsfühlern 23 in Verbindung steht.On the rear narrow side 21 of the housing 5 is a Control electronics housing 22 attached, which in the clamping head 1 end position sensors 23 in Connection is established.

Mit Rücksicht auf die Abfuhr der von den Motoren entwickelten Wärme kann das Gehäuse 5 im Bereich der Motoren 6 mit Wanddurchbrechungen 24 versehen sein, durch die eine direkte Wärmeabstrahlung ermöglicht wird. Abgesehen davon ist durch das insbesondere im Bereich der Motorenanordnung dünnwandige Gehäuse 5 per se zumindest für eine ausreichende Wärmeableitung gesorgt.With regard to the removal of those developed by the engines The housing 5 can heat in the area of the motors 6 with wall openings 24 be provided, through which a direct heat radiation is made possible. That being said, by that thin-walled housings, particularly in the area of the motor arrangement 5 per se at least for sufficient heat dissipation taken care of.

Was das die Motoren 6 aufnehmende Gehäuse 5 betrifft, so kann dieses vorteilhaft aus zwei Halbschalen 25 gebildet sein, die im Urformverfahren beispielsweise Druckgußverfahren hergestellt werden können. As for the housing 5 accommodating the motors 6, so can this advantageously be formed from two half-shells 25 which manufactured in the primary molding process, for example, die casting process can be.
