Description
Die Erfindung bezieht sich auf eine Schraubvorrichtung zum Einschrauben und Festziehen von Schrauben mit hohem Anzugs moment, die auf das Einschrauben und Festziehen von Schrauben mit einem Schrauber, der an einer ausziehbaren Teleskopstütze befestigt ist, gerichtet ist und bei der ferner der Schrauber ein Winkeldrehschrauber ist, dessen Schaft etwa senkrecht zur Teleskopstütze ausge richtet ist und an wenigstens einer entfernt von der Schraubachse liegenden Stelle an der Teleskopstütze befe stigt ist, wobei die Teleskopstütze eine Klemmvorrichtung zum Fixieren ihrer Länge aufweist, nach Patent P 28 30 906.0.The invention relates to a screw device for Screwing in and tightening screws with high tightening moment that on screwing and tightening screws with a screwdriver an extendable telescopic support is fixed, directed and in which the screwdriver is also an angle screwdriver is whose shaft extends approximately perpendicular to the telescopic support is directed and at least one away from the Position the screw axis on the telescopic support Stigt, the telescopic support is a clamping device for fixing their length, according to patent P 28 30 906.0.
Bei dieser Vorrichtung kann die Schwierigkeit auftreten, daß bei Ausstattung derselben mit einem Kraftverstärker die entstehenden höheren Momente nur ungenügend abgestützt sind.With this device, the difficulty may arise that when equipping them with a power amplifier resulting higher moments are insufficiently supported.
Der Erfindung liegt daher die Aufgabe zugrunde, die Vorrich tung nach dem Hauptpatent so zu verbessern, daß das gesamte am Drehschrauber entstehende Reaktionsmoment sicher und ohne das Entstehen freier Reaktionskräfte an der Teleskopstütze abgestützt wird.The invention is therefore based on the object, the Vorrich to improve after the main patent so that the whole reaction torque arising on the screwdriver safely and without the creation of free reaction forces on the telescopic support is supported.
Dies wird erfindungsgemäß dadurch erreicht, 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 Drehmomentenstütze des Kraftvervielfältigers in einer senkrecht zur Schraubachse ausgerichteten und durch die Mittelachse der Teleskopstütze verlaufenden Ebene an der Teleskopstütze abgestützt ist. This is achieved in that on the Output of the angle screwdriver in a manner known per se a force multiplier is attached and that the shaft of the angled screwdriver from the telescopic support has such a distance that a torque arm of the Power multiplier in a perpendicular to the screw axis aligned and through the central axis of the telescopic support level is supported on the telescopic support.
Durch diese erfindungsgemäße Ausbildung wird die gestellte Aufgabe in baulich einfacher Weise gelöst.Through this training according to the invention, the posed Task solved in a structurally simple manner.
Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung erläutert.An embodiment of the invention is based on the Drawing explained.
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 ausge bildet, weshalb er einen Druckluftanschluß 28 aufweist. 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 Winkel drehschraubers 8 so angepaßt, daß ein Handgriff einen Be tätigungsschalter 12 für den Winkeldrehschrauber enthält. Die Schraubachse des Winkeldrehschraubers ist mit 9 be zeichnet. Auf dem Abtrieb des Winkeldrehschraubers 8 ist ein sogenannter Kraftvervielfältiger 29 aufgesteckt, der mit einer Drehmomentstütze 26 in einer nach unten offenen Haltebohrung der Teleskopstütze 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 Teleskop stütze 6 verlaufenden Ebene abgestützt ist.The drawing shows the holder of a screwdriver on a telescopic support in side view. The lower part of a telescopic support is designated by 6 , an angle screwdriver by 8 . The angle screwdriver 8 is formed as a compressed air tool, which is why it has a compressed air connection 28 . The angled screwdriver 8 is attached to the lower end of the telescopic support 6 by means of two retaining clips 37, 38 . The retaining clips 37, 38 are adapted to the shaft of the angle rotary screwdriver 8 so that a handle contains an actuation switch 12 for the rotary screwdriver. The screw axis of the rotary screwdriver is marked with 9 be. On the output of the angular screwing device 8 a so-called torque multiplier 29 is plugged, the plugged with a torque arm 26 in a downwardly open retaining hole of the telescopic support 6 and is supported there. The distance of the shaft of the rotary screwdriver from the telescopic support 6 is chosen so large that the torque support 26 is supported in the plane perpendicular to the screw axis 9 and supported by the central axis of the telescopic support 6 .
