Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Einstellung zumindest der Lage eines Körpers gegenüber einem Referenzkörper nach dem Oberbegriff des Anspruches 1.The The invention relates to a device for adjusting at least the Position of a body relative to a reference body according to the preamble of claim 1.
Solche Körper sind beispielsweise Hauptspindeln in Dreh- und/oder Fräsmaschinen, Bearbeitungszentren und dergleichen oder Gegenspindeln in Drehmaschinen von Spindelantriebssystemen in Werkzeugmaschinen. Bei Instandsetzungen oder Reparaturen müssen diese Spindeln häufig ausgetauscht werden. Hierbei treten häufig Genauigkeitsprobleme auf, da die Maßtoleranzen zwischen der neuen und der auszutauschenden Spindel nicht gleich sind, so dass die Lage und die Orientierung der Spindelachse nach dem Austausch neu eingestellt werden müssen. Hierzu werden die Lage und der Orientierung der Spindeln in der Werkzeugmaschine so abgestimmt, dass das zu montierende Spindelaggregat zu seinen Bezugskörpern oder -flächen mittels Unterlegleisten, Distanzleisten, Hülsen und dergleichen eingestellt wird. Hierzu werden die Distanzleisten und dergleichen auf die zuvor ermittelten Maße geschliffen. Diese bekannte Lage- und Orientierungseinstellung von Spindelachsen ist sehr zeitaufwändig. Die Einstellzeit beträgt wenigstens einen Tag. Insbesondere ist nachteilig, dass die zusätzlichen Einstellelemente (Leisten, Hülsen, Distanzbolzen und dergleichen) als zusätzliche Komponenten in die Maschinenstruktur eingebracht werden müssen und diese dann möglicherweise das dynamische Verhalten der Werkzeugmaschine beeinflussen.Such For example, bodies are main spindles in lathe and / or Milling machines, machining centers and the like or Counter spindles in lathes of spindle drive systems in machine tools. For repairs or repairs, these spindles must frequently exchanged. This often occur Accuracy problems, since the dimensional tolerances between the new and the spindle to be replaced are not the same, so that the position and orientation of the spindle axis after replacement need to be reset. For this the situation and the Orientation of the spindles in the machine tool adjusted so that the spindle unit to be mounted to its reference bodies or surfaces by means of underlay strips, spacer strips, Sleeves and the like is set. To do this the spacer strips and the like to the previously determined dimensions ground. This known attitude and orientation setting of Spindle axes is very time consuming. The adjustment time is at least one day. In particular, it is disadvantageous that the additional adjustment elements (strips, sleeves, Spacer bolts and the like) as additional components in the machine structure must be introduced and this then possibly the dynamic behavior of the machine tool influence.

Mit den bekannten Vorgehensweisen verschlechtert sich die mechanische Schnittstelle zwischen den zu verbindenden und in ihrer Lage einzustellenden Komponenten. Es muss hierfür in der Maschine Bauraum vorgesehen werden. Insbesondere muss die Zugänglichkeit zu dieser mechanischen Schnittstelle gewährleistet sein.With the known procedures deteriorate the mechanical Interface between the connected and to be adjusted in their position Components. It must be provided for this space in the machine space become. In particular, accessibility to this must be be guaranteed mechanical interface.
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Vorrichtung so auszubilden, dass eine Korrektur des Körpers gegenüber dem Referenzkörper in einfacher Weise möglich ist.Of the Invention is based on the object, the generic Device so that a correction of the body relative to the reference body in a simple manner is possible.
Diese Aufgabe wird bei der gattungsgemäßen Vorrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.These Task is in the generic device according to the invention with the characterizing features of claim 1 solved.
Mit der erfindungsgemäßen Vorrichtung kann der Körper mittels des Doppelexzenters um die Größenordnung der Exzentrizität der beiden Exzenterhülsen verschoben werden. Das neue Zentrum des Körpers kann einen Kreis mit dem Radius r = e (Exzentrizität) um die ideal zentrische Lage der Achse des Körpers beschreiben. Die Exzentrizität der einen Exzenterhülse kann mit der zweiten Exzenterhülse wieder ausgeglichen werden, so dass der in den beiden Exzenterhülsen untergebrachte Körper so verstellt werden kann, dass sich seine Achse in jedem Falle im ursprünglichen Zentrum befindet. Ist der Körper beispielsweise die Spindel eines Spindelaggregats, dann kann die Spindel mit Hilfe des Doppelexzenters exakt in ihre Solllage ver stellt werden, wenn sich die Achse der Spindel infolge von Fertigungstoleranzen nicht in der Solllage befindet. Dadurch ist der Austausch von Spindelaggregaten problemlos möglich. Sollte sich aufgrund von Fertigungstoleranzen die Achse der ausgetauschten Spindel nicht in der Solllage befinden, dann kann mittels der beiden ineinandersitzenden Exzenterhülsen die Spindelachse problemlos in die Solllage eingestellt werden.With The device according to the invention may be the body by means of the double eccentric by the order of magnitude shifted the eccentricity of the two eccentric sleeves become. The new center of the body can be a circle with the radius r = e (eccentricity) about the ideal centric Describe the position of the axis of the body. The eccentricity the one eccentric sleeve can with the second eccentric sleeve be balanced again, so that in the two eccentric sleeves accommodated body can be adjusted so that its axis is in any case in the original center. For example, if the body is the spindle of a spindle unit, then the spindle with the help of the double eccentric exactly in their Target position ver be adjusted when the axis of the spindle due of manufacturing tolerances is not in the desired position. Thereby the replacement of spindle units is easily possible. Should the axis of the replaced spindle due to manufacturing tolerances not in the desired position, then by means of the two ineinanderitzenden Eccentric sleeves the spindle axis easily in the desired position be set.
Wird der Körper mit zwei mit Abstand voneinander liegenden Doppelexzentern gelagert, dann kann nicht nur die Lage, sondern auch die Orientierung des Körpers einfach eingestellt werden.Becomes the body with two spaced double eccentrics stored, then not only the location, but also the orientation of the body can be easily adjusted.
Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further Features of the invention will become apparent from the further claims, the description and the drawings.
