Title (EN) ARRANGEMENT FOR POSITIONING AN ACTUATOR DEVICE
(FR) DISPOSITIF DE POSITIONNEMENT D’UN DISPOSITIF D’ACTIONNEMENT
(DE) ANORDNUNG ZUR POSITIONIERUNG EINER AKTUATORVORRICHTUNG
Abstract:
(EN) The invention relates to an arrangement for a print head, comprising a support body for fixing the arrangement to the print head, an actuator device having a main body attached to the support body, the actuator device additionally comprising first means for moving a push-rod, by which means the push-rod is attached to the main body and, when electrically activated, is movable relative to the main body, the main body being in engagement with an element for positioning the actuator device relative to the support body, the arrangement comprising: a screw joint which is designed such that the screw joint movably attaches the basic body to the support body, the screw joint comprising a thread and a counter-thread which is screwed into the thread, a resilient element, wherein the screw joint and the at least one resilient element are designed to co-operate for positioning of the actuator device such that the thread and the counter-thread are clamped with a pretension with respect to one another and a rotation of the element causes a movement of the main body relative to support body along a translational direction.
(FR) L’invention concerne un dispositif, destiné à une tête d’impression, comprenant un corps de support destiné à fixer le dispositif sur la tête d’impression, un dispositif d’actionnement pourvu d’un corps de base qui est monté sur le corps de support. Le dispositif d’actionnement comprend en outre des premiers moyens qui sont destinés à déplacer un coulisseau et qui fixe le coulisseau au corps de base et le déplacent par rapport à celui-ci lorsqu’il est entraîné électriquement. Le corps de base est en engagement avec un élément de positionnement du dispositif d’actionnement par rapport au corps de support. Le dispositif comprend : - une articulation à vis qui est conçue de manière à monter le corps de base de manière mobile au corps de support, l’articulation à vis comprenant un filetage et un filetage homologue qui est vissé dans le filetage, - un élément élastique, l’articulation à vis et l’au moins un élément élastique étant conçue pour coopérer le dispositif d’actionnement de telle sorte que le filetage et le filetage homologue sont serrés avec une précontrainte l’un contre l’autre et une rotation de l’élément provoque un mouvement du corps de base par rapport au corps de support le long d’une direction de translation.
(DE) Anordnung für einen Druckkopf mit einem Tragkörper zur Fixierung der Anordnung am Druckkopf, einer Aktuatorvorrichtung mit einem Grundkörper, der am Tragkörper angebracht ist, wobei die Aktuatorvorrichtung zusätzlich erste Mittel umfasst zur Bewegung eines Stössels, über die der Stössel am Grundkörper angebracht ist und bei elektrischer Ansteuerung derselben relativ dazu bewegbar ist, wobei der Grundkörper mit einem Element zur Positionierung der Aktuatorvorrichtung relativ zum Tragkörper in Eingriff steht, wobei die Anordnung umfasst: - ein Schraubgelenk, das so ausgebildet ist, dass es den Grundkörper am Tragkörper beweglich anbringt, wobei das Schraubgelenk ein Gewinde und ein Gegengewinde umfasst, das in das Gewinde eingeschraubt ist, - ein elastisches Element, wobei das Schraubgelenk und das zumindest eine elastische Element für die Positionierung der Aktuatorvorrichtung zusammenwirkend so ausgebildet sind, dass das Gewinde und das Gegengewinde mit einer Vorspannung gegeneinander verklemmt werden und eine Drehung des Elements eine Bewegung des Grundkörpers relativ zum Tragkörper entlang einer Translationsrichtung bewirkt
