Description

Die vorliiegende Erfindung betrifft .eine Flächenschleif- und Poliervorrichtung für Werkstoffe verschiedener Härte, insbesondere für Gestein, bei der mehrere Schleifscheiben konzentrisch um eine-senkrechte Mittelachse angeordnet sind.The present invention relates to a surface grinding and polishing device for materials of different hardness, especially for stone, where several grinding wheels are arranged concentrically around a vertical central axis.

Es sind Vorrichtungen dieser Art bekannt, bei ,denen die Schleifscheiben außer ihrer planetenartigen-Umlaufbewegung um die Mittelachse eine Dreh- oder Drehpendelbewegung um ihre eigene, zur Mittelachse schräg gestellten Achse ausführen oder eine Pendelbewegung zur Erzielung einer linienförmigen Berührung zwischen Schleifscheiben und Werkstück erhalten.There are devices of this type known in which the grinding wheels in addition to their planetary orbital motion around the central axis, a rotary or rotary pendulum motion around their own axis, which is inclined to the central axis, or a pendulum movement to achieve linear contact between grinding wheels and workpiece obtain.

Die vorliegende Erfindung unterscheidet sich gegenüber den bekannten Vorrichtungen dddürch, ,daß die Schleifscheiben, die um ihre eigne Achse nicht rotieren, während ihres Umlaufes um die senkrechte Mittelachse eine taumelnde Bewegung ausführen. Dadurch wandern die Berührungslinien zwischen den Schleifscheiben und dem Werkstück spiralenförmig von innen nach außen und umgekehrt, wodurch sich eine besonders breite ringförmige Schleiffläche ergibt, deren' innerer Halbmesser dem kleinsten Abstand der innersten Berührungslinien und deren äußerer Halbmesser dem größten Abstand der äußersten Berührungslinien von .der Mittelachse entspricht. Es wird also innerhalb einer bestimmten Zeiteinheit eine außergewöhnlich große Fläche des Werkstückes- durchdie Schleifscheiben berührt und eine : wesentlich höhere Leistung und größere Sauberkeit des Schliffes gegenüber den seither bekannten Vorrichtungen erzielt.The present invention differs from the known ones Devices dddürch that the grinding wheels, which do not rotate about their own axis, perform a tumbling motion while revolving around the vertical central axis. This causes the lines of contact to move between the grinding wheels and the workpiece spirally from the inside out and vice versa, which creates a particularly wide ring-shaped grinding surface results, whose 'inner radius the smallest distance the innermost lines of contact and their outer radius the greatest distance corresponds to the outermost lines of contact of .the central axis. So it becomes within an extraordinarily large area of the workpiece touched by the grinding wheels and one: significantly higher performance and greater Achieved cleanliness of the cut compared to the devices known since then.

Die Zeichnung zeigt eine Ausführungsform des Erfindungsgegenstandes. Auf der senkrechten Antriebsachse i ist der Schleifscheibenträger a befestigt, in dem die Achsen 3 der Schleif sicheiben ¢ nach allen Richtungen schwenkbar gelagert sind. Durch die als Exzenter .ausgebildeten Zahnräder 5 werden die Achsen 3 und damit .die Schleifscheiben 4 in taumelnde Bewegung versetzt. Zum Antrieb ,der Taumelbewegung dient das Übersetzungsgetriebe 6, 7, 8, 9, welches in .dem feststehenden Führungsteil ich gelagert ist. Es. bewirkt, daß das dlie Exzenterrä.der antreibende, auf der Antriebswelle i lose laufende Doppelrad 9 eine Geschwindigkeit erhält, die von der Geschwindigkeit der Antriebswelle i nur wenig verschieden ist. Dadurch wird erreicht, daß auf eine Umlaufbewegung der Schleifvorrichtung nur ein Bruchteil einer Taumelbewegung entfällt.The drawing shows an embodiment of the subject matter of the invention. The grinding wheel carrier a is attached to the vertical drive axis i, in which the axes 3 of the grinding disks ¢ mounted pivotable in all directions are. The gears 5, which are designed as an eccentric, are the axes 3 and so .the grinding wheels 4 set in a tumbling motion. To the drive, the tumbling movement serves the transmission gear 6, 7, 8, 9, which in .dem fixed guide part i is stored. It. causes the eccentric wheel to be the driving force on the Drive shaft i loosely running double wheel 9 receives a speed that of the Speed of the drive shaft i is only slightly different. This achieves that only a fraction of a wobbling movement occurs on a rotary movement of the grinding device not applicable.
