Abstract
Description
Die Erfindung betrifft ein Schraubwerkzeug mit einer Antriebseinrichtung nach der im Oberbegriff von Anspruch 1 näher definierten Art.The The invention relates to a screwing tool with a drive device according to the closer defined in the preamble of claim 1 Art.
Derartige Schraubwerkzeuge sind aus dem allgemeinen Stand der Technik bekannt. Sie werden nicht nur zum Anziehen von Schrauben oder Muttern mit einem bestimmten Drehmoment eingesetzt, sondern müssen häufig auch in der Lage sein, das zu schraubende Bauteil, also die Schraube oder die Mutter, exakt zu positionieren. Eine bestimmte Positionierung der Schraube kann dabei sowohl technisch notwendige als auch rein optisch bedingte Gründe haben und es ist teilweise eine Genauigkeit von weniger als 10 erforderlich.such Screwing tools are known from the general state of the art. They are not only used for tightening screws or nuts used a certain torque, but often need too be able to screw the component, so the screw or the mother to position accurately. A specific positioning The screw can be both technically necessary and pure optical reasons have partial accuracy of less than 10 is required.
Die bekannten Lösungen sehen hierzu beispielsweise inkrementale Messsysteme vor, die jedoch bei jedem Schraubvorgang das Anfahren eines Referenzpunktes erfordern, was zu einem sehr hohen Zeitverlust führt. Unter anderem aus diesem Grund können die genannten Inkrementalmesssysteme nicht bei sämtlichen Schraubprozessen eingesetzt werden.The known solutions For this purpose, for example, provide incremental measuring systems, which however require the approach of a reference point with each screwdriving process, which leads to a very high loss of time. Among other things, for this reason can the mentioned incremental measuring systems are not used in all screwdriving processes become.
Eine weitere Möglichkeit zur Ermittlung des Lagewinkels der Abtriebswelle besteht in der Anbringung einer zusätzlichen Optik außerhalb des Werkzeugs, was jedoch einen sehr großen Aufwand darstellt und somit hohe Kosten verursacht.A another possibility for determining the position angle of the output shaft is in the Attachment of an additional Optics outside of the tool, but this is a very big effort and thus high costs caused.
Es ist daher Aufgabe der vorliegenden Erfindung, ein Schraubwerkzeug zu schaffen, bei welchem mit möglichst einfachen Mitteln und einer möglichst hohen Genauigkeit der Lagewinkel der mit dem zu schraubenden Bauteil verbindbaren Abtriebswelle ermittelt werden kann, so dass ein genaues Positionieren des zu schraubenden Bauteils möglich ist.It is therefore an object of the present invention, a screwing to create, with which as possible simple means and one possible high accuracy of the attitude angle of the component to be screwed connectable output shaft can be determined, so that an accurate Positioning of the component to be screwed is possible.
Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention this Problem solved by the features mentioned in claim 1.
Durch die erfindungsgemäße Ausführung der Einrichtung zum Ermitteln des Lagewinkels der Abtriebswelle mit einem Positionsgeber und einem in unmittelbarer Nähe desselben angeordneten Positionssensor ergibt sich durch die Verbindung des Positionsgebers mit der Abtriebswelle ein Absolutmesssystem, welches den Lagewinkel der Abtriebswelle direkt anzeigt. Dadurch kann der Lagewinkel der Abtriebswelle zu jedem Zeitpunkt festgestellt werden, wodurch es möglich ist, ein mit dem erfindungsgemäßen Schraubwerkzeug einzuschraubendes Bauteil exakt zu positionieren.By the embodiment of the invention Device for determining the position angle of the output shaft with a position transmitter and one in the immediate vicinity thereof arranged position sensor results from the connection of the Position transmitter with the output shaft an absolute measuring system, which indicates the position angle of the output shaft directly. This allows the Position angle of the output shaft can be determined at any time, thereby it possible is, one with the screwing tool according to the invention exactly position the part to be screwed in.
Vorteilhafterweise handelt es sich hierbei um eine sehr einfache Lösung, die insbesondere eine einfache Handhabung ermöglicht.advantageously, this is a very simple solution, especially a simple one Handling possible.
Eine praxistaugliche Ausführungsform der Erfindung, bei der die Abtriebswelle nicht wesentlich abgeändert werden muss, sodass die Erfindung auch bei bestehenden Schraubwerkzeugen eingesetzt werden kann, ergibt sich, wenn in einer vorteilhaften Ausgestaltung der Erfindung der Positionsgeber mit der Abtriebswelle über eine Umlenkeinrichtung verbunden ist.A Practical embodiment the invention in which the output shaft are not changed significantly must, so that the invention even with existing screwdrivers can be used results, if in an advantageous embodiment the invention of the position sensor with the output shaft via a Bypass is connected.
Hierbei kann auf zusätzliche Sensoren oder sonstige zusätzliche Messeinrichtungen verzichtet werden, wenn die Umlenkeinrichtung so ausgebildet ist, dass die Drehzahl des Positionsgebers im wesentlichen der Drehzahl der Abtriebswelle entspricht.in this connection can on additional Sensors or other additional Measuring devices are waived if the deflection is formed so that the speed of the position sensor substantially the speed of the output shaft corresponds.
Die Umlenkeinrichtung kann beispielsweise als Riemengetriebe oder als Zahnradgetriebe ausgebildet sein.The Diverter can, for example, as a belt transmission or as To be formed gear transmission.
Besonders exakte Messergebnisse sind zu erwarten, wenn der Positionssensor als Magnetfeldsensor ausgebildet ist.Especially exact measurement results are expected when the position sensor is designed as a magnetic field sensor.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung prinzipmäßig beschrieben.following is an embodiment of Invention described in principle with reference to the drawing.
Die einzige Figur zeigt eine Schnittdarstellung eines erfindungsgemäßen Schraubwerkzeugs.The single figure shows a sectional view of a screwing tool according to the invention.
