Abstract
Description
Die vorliegende Erfindung betrifft eine Werkzeugmaschine, mit mehreren je aus ineinander angeordneten Rohren gebildeten Teleskoparmen, die einerseits an einem Rahmen und andererseits an einer Werkzeugaufnahme gelenkig befestigt sind. Eine derartige Werkzeugmaschine ist beispielsweise aus der US-A 54 01 128 bekannt. Im Gegensatz zu konventionellen Werkzeugmaschinen werden hier geringere Massen bewegt. Dies hat zur Folge, daß höhere Stell geschwindigkeiten gefahren werden, wobei insbesondere die Steifigkeit zwi schen Rahmen und Werkzeugaufnahme sehr hoch ist. In vielen Fällen sind insgesamt sechs Teleskoparme vorgesehen, wobei alle Teleskoparme vonein ander unabhängig ein- bzw. ausgefahren werden können. Dies hat zur Folge, daß die Werkzeugaufnahme jede gewünschte Position im Raum einnehmen kann. Eine hohe Steifigkeit der Teleskoparme ist bei derartigen Werkzeugma schinen von besonders großer Bedeutung.The present invention relates to a machine tool, each with several tubes arranged in one another formed telescopic arms on the one hand a frame and on the other hand articulated to a tool holder are. Such a machine tool is known for example from US-A 54 01 128 known. In contrast to conventional machine tools lower masses are moved here. As a result, higher positions speeds are driven, in particular the stiffness between frame and tool holder is very high. In many cases a total of six telescopic arms are provided, all telescopic arms of one can be retracted or extended independently. As a consequence, that the tool holder take up any desired position in the room can. A high degree of rigidity of the telescopic arms is with such tool dimensions seem of great importance.
Aufgabe der vorliegenden Erfindung ist es daher, eine gattungsgemäße Werk zeugmaschine derart weiterzubilden, daß die Teleskoparme einerseits sehr steif ausgebildet und andererseits leichtgängig ein- bzw. ausfahrbar gebildet sind.The object of the present invention is therefore a generic work to further develop the machine tool in such a way that the telescopic arms are very stiff on the one hand trained and on the other hand smoothly retractable or extendable.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das äußere Rohr mit mehreren über den Umfang verteilten Aussparungen versehen ist, in denen Kugelumlaufeinheiten angeordnet sind, die jeweils aus einem Tragkörper mit einer in einen Lastabschnitt und einen daran anschließenden lastfreien Rückfüh rungsabschnitt unterteilten endlosen Kugelrille bestehen, an deren Lastabschnitt und an einer an dem inneren Rohr vorgesehenen, dem Lastabschnitt gegen über liegenden Kugelrille Kugeln abwälzen, die aus den Lastabschnitt in den Rück führungsabschnitt geführt werden. Bei dieser Anordnung ist eine leichtgängige Verschiebbarkeit der Teleskoparme gewährleistet, wobei das innere und das äußere Rohr mittels der Kugellagerung zueinander verdrehgesichert sind. Die Länge des Lastabschnitts bzw. die Anzahl der im Lastabschnitt abwälzenden Kugeln wird entsprechend der Geometrie des Teleskoparms bzw. entsprechend den zu erwartenden Belastungen ausgelegt. Vorzugsweise sind mehrere über den Umfang des inneren Rohres verteilt angeordnete Paare von Kugelrillen vorgesehen, wobei die zueinander parallelen, einander benachbarten Kugelril len eines jeden Paares gegenläufig geneigt sind. Die Tragkörper der Kugel umlaufeinheiten sind entsprechend mit Paaren von Kugelrillen versehen, so daß im Querschnitt gesehen jeweils zweireihige Schrägkugellager gebildet sind, wobei die beiden Drucklinien der Kugelreihen vorzugsweise einen Winkel von ca. 90° einschließen.According to the invention this object is achieved in that the outer tube with several recesses distributed over the circumference are provided, in which Recirculating ball units are arranged, each with a support body one in a load section and a subsequent load-free return tion section divided endless ball groove exist at the load section and at a provided on the inner tube, the load section opposite lying ball groove roll off balls from the load section into the back guide section. This arrangement is easy Movability of the telescopic arms ensured, the inner and the outer tube are secured against rotation by means of the ball bearing. The Length of the load section or the number of rolling in the load section Balls are made according to the geometry of the telescopic arm or designed for the expected loads. Preferably, several are over the circumference of the inner tube arranged pairs of ball grooves provided, the mutually parallel, adjacent Kugelril len of each pair are inclined in opposite directions. The supporting body of the ball Circulation units are correspondingly provided with pairs of ball grooves, so that seen in cross section, double-row angular contact ball bearings are formed, the two pressure lines of the rows of balls preferably having an angle of enclose approx. 90 °.
Bei einer weiteren erfindungsgemäßen Weiterbildung ist vorgesehen, daß das äußere Rohr mit einer quer zur Längsachse angeordneten Tangentialbohrung versehen ist, wobei der Tragkörper mit einer zu der Tangentialbohrung koaxia len Gewindebohrung versehen ist, in die eine durch die Tangentialbohrung durchgeführte Schraube eingreift. Die Anlagefläche ist durch eine Wand der Aussparung gebildet, in der der Tragkörper angeordnet ist. Mittels Anziehen der Schraube wird der Tragkörper gegen diese Anlagefläche gepreßt, wobei ggf. zwischen Anlagefläche und Tragkörper Ausgleichsbeilagen zur einwandfreien Positionierung des Tragkörpers vorgesehen sein können. Zur radialen Abstüt zung der Kugelumlaufeinheit ist die äußere Mantelfläche des äußeren Rohres mit einem Deckel versehen, wobei dem Deckel eine Abflachung an der äuße ren Mantelfläche des äußeren Rohres zugeordnet ist. Vorzugsweise bildet der Deckel im Querschnitt gesehen einen Kreisabschnitt des äußeren Rohres. Auf diese Weise weist das äußere Rohr eine glattzylindrische Mantelfläche auf, ohne daß Verletzungsgefahr durch Vorsprünge und Kanten besteht. Der Deckel mag zweckmäßigerweise mittels Schrauben mit dem äußeren Rohr verbunden sein.In a further development according to the invention it is provided that the outer tube with a tangential bore arranged transversely to the longitudinal axis is provided, the support body having a coaxial to the tangential bore len threaded bore is provided, in one through the tangential bore performed screw engages. The contact surface is through a wall Formed recess in which the support body is arranged. By tightening the Screw the support body is pressed against this contact surface, whereby if necessary between the contact surface and the supporting body compensation inserts for perfect Positioning of the support body can be provided. For radial support The ball recirculation unit is the outer surface of the outer tube provided with a lid, the lid being flattened on the outside ren outer surface of the outer tube is assigned. Preferably, the Cover seen in cross section a circular section of the outer tube. On in this way, the outer tube has a smooth cylindrical outer surface without that there is a risk of injury from protrusions and edges. The lid likes expediently be connected to the outer tube by means of screws.
