Description
Die Erfindung betrifft eine Zentrisch-Spannvorrichtung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a centric clamping device according to the preamble of
Zentrisch-Spannvorrichtungen weisen üblicherweise einen z.B. auf einem Maschinentisch aufspannbaren Grundkörper, zwei an dem Grundkörper über Längsführungen verschiebbar geführte Spannbacken und eine Verstellspindel zur gegenläufigen Verstellung der beiden Spannbacken auf. Mit Hilfe der Verstellspindel können die am Grundkörper verschiebbar angeordneten Spannbacken gleichzeitig auseinander- und zusammengefahren werden, wodurch eine zentrische Spannung von Werkstücken ermöglicht wird.Centric clamping devices usually have a base body that can be clamped, e.g. With the help of the adjusting spindle, the clamping jaws, which are movably arranged on the base body, can be moved apart and together at the same time, which enables centric clamping of workpieces.

Aufgabe der Erfindung ist es, eine Zentrisch-Spannvorrichtung der eingangs genannten Art zu schaffen, die eine gegen Verschmutzung optimal geschützte Spindelllagerung mit hoher Genauigkeit enthält.The object of the invention is to create a centric clamping device of the type mentioned at the outset, which contains a highly accurate spindle bearing that is optimally protected against contamination.
Diese Aufgabe wird durch eine Zentrisch-Spannvorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Weiterbildungen und vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a centric clamping device with the features of
Bei der erfindungsgemäßen Zentrisch-Spannvorrichtung ist die Spindellagerung in einem Lagerblock untergebracht und weist zwei innerhalb des Lagerblocks axial verstellbare Lagerhülsen auf. Durch die axiale Verstellung der beiden Lagerhülsen kann nicht nur axiale Lage der Verstellspindel bezüglich des Grundkörpers eingestellt werden, über eine gegenseitige Verstellung der beiden Lagerhülsen kann die Spindellagerung außerdem vorgespannt und spielfrei eingestellt werden. Dadurch ist eine hohe Präzision und gute Wiederholgenauigkeit erreichbar. Außerdem ist die Verstellspindel über den Lagerblock im Bereich der Lagerung komplett abgedeckt und abgedichtet. Die Zentrisch-Spannvorrichtung ist somit unempfindlich gegen Späne und die Verstellspindel ist in einem geschlossenen System vor Verschmutzungen geschützt.In the centric clamping device according to the invention, the spindle bearing is accommodated in a bearing block and has two bearing sleeves that are axially adjustable within the bearing block. By axially adjusting the two bearing sleeves, not only can the axial position of the adjusting spindle be adjusted with respect to the base body, but the spindle bearing can also be preloaded and adjusted without play by mutual adjustment of the two bearing sleeves. As a result, high precision and good repeatability can be achieved. In addition, the adjusting spindle is completely covered and sealed by the bearing block in the bearing area. The centric clamping device is therefore insensitive to chips and the adjusting spindle is protected from contamination in a closed system.
In einer besonders reibungsarmen und positionsgenau einstellbaren Ausführung kann die Spindellagerung als Rollenlagerung mit mehreren zwischen den Lagerhülsen und der Verstellspindel geführten Wälzkörpern ausgebildet sein. Die Verstellspindel kann hierzu z.B. zwei voneinander beabstandete Ringnuten zur innenseitigen Lagerung der z.B. als Kugeln ausgebildeten Wälzköper aufweisen. Die beiden Lagerhülsen können an den einander zugewandten Stirnseiten jeweils eine schulterförmige Lagerfläche zur außenseitigen Lagerung der Wälzköper enthalten. Durch gegenseitiges Verspannen der beiden Lagerhülsen, können die schulterförmigen Lagerflächen zur Anlage an den Kugeln gebracht und somit eine möglichst spielfreie Einstellung erreicht werden. Die Spindellagerung könnte aber auch als Gleitlagerung mit axial verstellbaren Gleitlagerhülsen ausgebildet sein.In a particularly low-friction embodiment that can be precisely positioned, the spindle bearing can be designed as a roller bearing with a plurality of rolling bodies guided between the bearing sleeves and the adjusting spindle. For this purpose, the adjusting spindle can, for example, have two annular grooves spaced apart from one another for the inside bearing of the rolling bodies, which are designed, for example, as balls. The two bearing sleeves can each contain a shoulder-shaped bearing surface for the outside bearing of the rolling bodies on the end faces facing one another. By mutual bracing of the two bearing sleeves, the shoulder-shaped bearing surfaces can be brought into contact with the balls and thus an adjustment with as little play as possible can be achieved. However, the spindle bearing could also be designed as a plain bearing with axially adjustable plain bearing sleeves.
Eine einfache axiale Verstellung der Lagerhülsen kann dadurch erreicht werden, dass die beiden Lagerhülsen jeweils ein Außengewinde zum Eingriff in ein entsprechendes Innengewinde einer durch den Lagerblock verlaufenden Durchgangsöffnung aufweisen.A simple axial adjustment of the bearing sleeves can be achieved in that the two bearing sleeves each have an external thread for engaging in a corresponding internal thread of a through-opening running through the bearing block.
In einer besonders stabilen und vor Verschmutzung optimal geschützten Bauweise kann der über den gesamten Umfang geschlossene Lagerblock einteilig mit dem Grundkörper ausgebildet sein. Ein optimierter Späneabfluss ist dadurch erreichbar, dass von Vertiefungen zwischen dem Lagerblock und zwei Seitenwangen des Grundkörpers nach außen führende Durchgänge mit schräg nach unten führenden Bodenflächen angeordnet sind.In a particularly stable construction that is optimally protected against contamination, the bearing block, which is closed over the entire circumference, can be designed in one piece with the base body. An optimized chip flow can be achieved by indentations between the bearing block and two side walls of the base body leading to the outside passages are arranged with sloping bottom surfaces leading downwards.
Gemäß einer weiteren vorteilhaften Ausführung können die beiden Spannbacken über in dem Grundkörper verschiebbar geführte Schieber verstellbar sein. Die Schieber können so in den Grundkörper eingebaut sein, dass sich eine vor Verschmutzung geschützte und gegen Späne unempfindliche Bauweise ergibt. Die Verstellspindel weist zweckmäßigerweise zwei als Rechts- bzw. Linksgewinde ausgeführte Außengewinde zum Eingriff mit entsprechenden Innengewinden an Durchgangsbohrungen der beiden Schieber auf.According to a further advantageous embodiment, the two clamping jaws can be adjustable via slides that are slidably guided in the base body. The slides can be installed in the base body in such a way that the result is a construction that is protected from dirt and is insensitive to chips. The adjusting spindle expediently has two external threads designed as right-hand and left-hand threads for engagement with corresponding internal threads on through-bores of the two slides.
Die Spannbacken sind vorzugsweise lösbar auf den Schiebern befestigt. Dadurch können die Spannbacken bei Bedarf ausgetauscht und an die jeweilige Spannaufgabe angepasst werden. Die Spannbacken können eine beliebige Form aufweisen.The clamping jaws are preferably releasably attached to the slides. As a result, the clamping jaws can be exchanged if necessary and adapted to the respective clamping task. The clamping jaws can have any shape.
