Description

Mehrspindelschleifkopf, insbesondere für Steinbearbeitung Die Erfindung betrifft einen Schleifkopf, insbesondere für Steinbearbeitung, mit planetarischer Anordnung von mehreren vorzugsweise konischen, auf nach oben divergierenden Spindeln angebrachten Schleifkörpern. Er ist bestimmt für Universal-, Schleif-, Säge- und Fräsmaschinen.Multi-spindle grinding head, especially for stone processing The invention relates to a grinding head, especially for stone processing, with planetary Arrangement of several, preferably conical, spindles that diverge upwards attached grinding tools. It is intended for universal, grinding, sawing and Milling machines.

Bei bekannten Maschinen dieser Art, z. B. solchen mit Drehzahlen von 200 bis 400 UpM und Leistungen bis etwa 6 kW, wird der Schleifkopf elastisch an der Antriebswelle gelagert. Hierbei dreht sich der Schleifspindelträger mit der Drehzahl der antreibenden Welle. Gleichzeitig werden die Drehzahlen der einzelnen Schleifkörper über ein Planetengetriebe ins Schnelle übersetzt. Die Verwendung solcher Schleifköpfe scheidet bei Maschinen mit einer Drehzahl der Antriebswelle von etwa 1500 UpM und Leistungen von 15 bis 40 kW aus; da die Schleifkörper hier die zulässigen Drehzahlen weit überschreiten würden.In known machines of this type, e.g. B. those with speeds of 200 to 400 rpm and powers up to about 6 kW, the grinding head becomes elastic mounted on the drive shaft. The grinding spindle support rotates with the Speed of the driving shaft. At the same time the speeds of each Grinding body translated into high speed via a planetary gear. The use of such In machines with a drive shaft speed of approx 1500 rpm and powers from 15 to 40 kW; because the grinding tools here are the permissible ones Would exceed speeds far.

Die erfindungsgemäße Ausbildung eines Schleifkopfes oben gekennzeichneter Art ermöglicht dagegen die Verwendung auch an schnellaufenden Maschinen dadurch, daß die hohe Drehzahl der Antriebswelle über ein Zwischengetriebe stark untersetzt wird und so dem Schleifspindelträger die noch zulässige niedrige Drehzahl erteilt, während die Drehzahl der einzelnen Schleifkörper ins Schnelle übersetzt wird, um den Verhältnissen angepaßte, optimale Schnittgeschwindigkeiten zu erzielen. Die Leistungsaufnahme dieser Schleifköpfe ist gegenüber Topfschleifscheiben sehr klein. Durch Vergrößerung der Spantiefe wird eine größere Zerspanungsleistung erzielt, wodurch gleichzeitig die Arbeitszeit auf Bruchteile der bisherigen Werte verringert wird.The inventive design of a grinding head marked above Art, on the other hand, enables use on high-speed machines by that the high speed of the drive shaft is greatly reduced via an intermediate gear and so the grinding spindle carrier is given the still permissible low speed, while the speed of the individual grinding wheels is quickly translated to to achieve optimal cutting speeds adapted to the circumstances. the The power consumption of these grinding heads is very low compared to cup grinding wheels. By increasing the depth of cut, a greater stock removal rate is achieved, which at the same time reduces working hours to a fraction of the previous values will.

Die Abbildung zeigt eine Ausführungsform eines erfindungsgemäß weitergebildeten Mehrspindelschleifkopfes.The figure shows an embodiment of a further developed according to the invention Multi-spindle grinding head.

Das ganze Aggregat ist drehbar auf einer Büchse 6 gelagert, die mit dem Antrieb z. B. der Motorwelle 3, axial und radial fest verbunden, beispielsweise verschraubt ist. Das feststehende Sonnenrad 5 der Planetengetriebeanordnung stützt sich mitKlauen4 radial an einem entsprechenden Klauenkranz 2 eines ortsfesten Maschinenflansches 1 ab. Die Spindeln 9 der Schleifkörper 12 greifen mit kleinen, oberen Planetenrädern 10 in das stehende Sonnenrad 5 und mit größeren, unteren Planetenrädern 11 in das drehende Sonnenrad 7 auf der Wellenbüchse 6 ein. Bei rotierender Hauptwelle 3 ergibt sich eine verhältnismäßig hohe Drehzahl an den Schleifkörperspindeln 12 mit verhältnismäßig niedriger Drehzahl des Schleifspindelträgers B.The whole unit is rotatably mounted on a sleeve 6, which is connected to the drive z. B. the motor shaft 3, axially and radially firmly connected, for example screwed. The stationary sun gear 5 of the planetary gear arrangement is supported with claws 4 radially on a corresponding claw ring 2 of a stationary machine flange 1 . The spindles 9 of the grinding bodies 12 engage with small, upper planetary gears 10 in the stationary sun gear 5 and with larger, lower planetary gears 11 in the rotating sun gear 7 on the shaft sleeve 6. When the main shaft 3 rotates, there is a relatively high speed of the grinding wheel spindles 12 with a relatively low speed of the grinding spindle carrier B.
