Abstract

The pneumatic nut runner (8) is mounted on a telescopic arm (6). A torque multiplier (29) is fitted between the output shaft of the nut runner and the socket head (9). The torque multiplier consists of an epicyclic reduction gear with an attached stud (26) which screws into the end of the telescopic arm. The nut runner (8) is secured to the telescopic arm by clamps (37, 38) which form part of the handle (12) which is attached to the barrel of the nut runner.

Description

Schraubvorrichtung zum Einschrauben und Screwing device for screwing in and

Festziehen von Schrauben mit hohem Anzugsmoment Zusatzanmeldung zu Patent . ... ... (Patentanm. P 28 30 906.0) Die Erfindung des Hauptpatents bezieht sich auf eine Schraubvorrichtung zum Einschrauben und Festziehen von Schrauben mit hohem Anzugsmoment. Eine solche Schraubvorrichtung soll gemäß Aufgabe der Erfindung des Hauptpatents so gestaltet werden, daß nur minimale Geräuschentwicklung auftritt, daß sie einfach handhabbar ist und mit geringem baulichem Aufwand verwirklicht werden kann. Zur Lösung dieser Aufgabe wird entsprechend einer bevorzugten Ausführungsform des Hauptpatents vorgeschlagen, eine an einer Deckenschiene hängende ausziehbare Teleskopstütze mit einem an diesem befestigten Winkeldrehschrauber zu versehen, wobei dessen Schaft parallel zur Teleskopstütze ausgerichtet ist. Durch diese Ausbildung läßt sich das Reaktionsmoment beimAnziehen einer Schraube in Form einer Querkraft auf die Teleskopstütze übertragen. Tightening screws with high tightening torque Patent. ... ... (Patent registration P 28 30 906.0) The invention of the main patent relates on a screwing device for screwing in and tightening screws with high tightening torque. Such a screwing device is intended according to the object of the invention of the main patent are designed so that only minimal noise occurs, that it is easy to handle and can be implemented with little structural effort can. To solve this problem, according to a preferred embodiment of the main patent proposed an extendable hanging on a ceiling rail To provide telescopic support with an angled screwdriver attached to it, the shaft of which is aligned parallel to the telescopic support. Through this training the moment of reaction when tightening a screw can be in the form of a transverse force transferred to the telescopic support.

Es hat sich gezeigt, daß es vorteilhaft ist, auf dem Abtrieb von Winkeldrehschraubern sogenannte Kraftvervielfältiger - das sind Untersetzungsgetriebe im Regelfall in Planetenbauart - anzuordnen, mit denen das Abtriebsdrehmoment der Winkelschrauber erhöht werden kann. Diese Kraftvervielfältiger weisen eine Drehmomentstütze auf, mit der das überhöhte Drehmoment an einem ortsfesten Punkt abgestützt werden muß.It has been shown that it is advantageous on the output of angled screwdrivers so-called power multipliers - these are reduction gears as a rule in Planetary design - to be arranged with which the output torque of the angle screwdriver can be increased. These force multipliers have a torque arm, with which the excessive torque must be supported at a fixed point.

Aufgabe der vorliegenden Erfindung ist es, eine Schraubvorrichtung der gattungsgemäßen Art so auszubilden, daß das gesamte am Drehschrauber entstehende Reaktionsmoment sicher -und ohne das Entstehen freier Reaktionskräfte an der Teleskopstütze abgestützt wird.The object of the present invention is to provide a screwing device of the generic type in such a way that the entire resultant on the screwdriver Reaction torque safe - and without the creation of free reaction forces on the telescopic support is supported.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß auf dem Abtrieb des Winkeldrehschraubers in an sich bekannter Weise ein Kraftvervielfältiger aufgesteckt ist und daß der Schaft des Winkeldrehschraubers von der Teleskopstütze einen solchen Abstand aufweist, daß eine Drehmomentstütze des Kraftvervielfältigers in einer senkrecht zur Schraubachse ausgerichteten und durch die Mittelachse der Teleskopstütze verlaufenden Ebene an der Teleskopstütze abgestützt ist.To solve this problem it is proposed according to the invention that a power multiplier on the output of the angled screwdriver in a manner known per se is attached and that the shaft of the angle screwdriver from the telescopic support has such a distance that a torque arm of the force multiplier in a perpendicular to the screw axis and through the central axis of the Telescopic support extending plane is supported on the telescopic support.

Durch diese erfindungsgemäße Ausbildung wird die gestellte Aufgabe in baulich einfacher Weise gelöst.The task set is achieved by this training according to the invention solved in a structurally simple way.

Ein Ausführungsbeispiel der Erfindung wird anhand der beigefügten Zeichnung erläutert. Die Zeichnung zeigt die Halterung eines Drehschraubers an einer Teleskopstütze in Seitenansicht. Der untere Teil einer Teleskopstütze ist dabei mit 6 bezeichnet, ein Winkeldrehschrauber mit 8. Der Winkeldrehschrauber 8 ist als Druckluftwerkzeug ausgebildet, weshalb er einen Druckluftanschluß 28 aufweist.An embodiment of the invention is based on the attached Drawing explained. The drawing shows the mounting of a screwdriver on a Telescopic support in side view. The lower part of a telescopic support is included denoted by 6, an angle screwdriver with 8. The angle screwdriver 8 is as Compressed air tool is formed, which is why it has a compressed air connection 28.

Die Befestigung des Winkeldrehschraubers 8 am unteren Ende der Teleskopstütze 6 erfolgt mittels zweier Halteklammern 37, 38. Die Halteklammern 37, 38 sind dem Schaft des Winkeldrehschraubers 8 so angepaßt, daß ein Handgriff einen Betätigungsschalter 12 für den Winkeldrehschrauber enthält.The fastening of the angle screwdriver 8 at the lower end of the telescopic support 6 takes place by means of two retaining clips 37, 38. The retaining clips 37, 38 are the Shank of the angle screwdriver 8 adapted so that a handle has an operating switch 12 for the angle nutrunner.

Die Schraubachse des Winkeldrehschraubers ist mit 9 bezeichnet. Auf dem Abtrieb des Winkeldrehschraubers 8 ist ein sogenannter Kraftvervielfältiger 29 aufgesteckt, der mit einer Drehmomentstütze 26 in einer nach unten offenen Haltebohrung der Teleskop stütze 6 steckt und sich dort abstützt. Der Abstand des Schaftes des Winkeldrehschraubers von der Teleskopstütze 6 ist gerade so groß gewählt, daß die Drehmomentstütze 26 in der senkrecht zur Schraubachse 9 ausgerichteten und durch die Mittelachse der Teleskopstütze 6 verlaufenden Ebene abgestützt ist.The screw axis of the angled screwdriver is denoted by 9. on the output of the angle screwdriver 8 is a so-called force multiplier 29 attached, with a torque arm 26 in a holding hole that is open at the bottom the telescopic support 6 is inserted and supported there. The distance between the shaft of the Angle screwdriver from the telescopic support 6 is just chosen so large that the Torque support 26 aligned perpendicular to the screw axis 9 and through the central axis of the telescopic support 6 extending plane is supported.
