Description
Die Erfindung betrifft eine Feinstschleifmaschine, bei der zur Erzielung einer leichten und billigen Bauart der Maschine -bei trotzdem großer Arbeitsgenauigkeit und Rattermarkenfreiheit 'die Schwingungen aussendende: Teile, Motor, Getriebe usw., vom Gestell und somit auch von der Werkstück- und Schleifscheibenlagerung durchschwingungsdämpf ende Zwischenlagen getrennt sind.The invention relates to a fine grinding machine in which to achieve a light and cheap construction of the machine -with nevertheless great working accuracy and chatter marks freedom 'emitting the vibrations: parts, motor, gearbox, etc., from the frame and thus also from the workpiece and grinding wheel bearings, vibration damping ends Intermediate layers are separated.
to Es sind bereits Schleifmaschinen mit einer leichten und billigen Bauart des Maschinengestells bekannt. Bei diesen Maschinen soll die erforderliche Starrheit und Schwingungsfreiheit des Gestells durch in ganz bestimmter Weise und Form verschweißte Stahlbleche erreicht werden. In der Praxis hat sich jedoch ergeben, daß die in dem Maschinengestell vorhandenen Schwiiigungsausschläge erst durch Verwendung ganz bestimmter und zusätzlicher Dämpfungsmittel geschwächt werden können und auch hierdurch kaum so, daß diese Gestelle in Stahlbauweise für Hochleistungsschleifmaschinen verwendbar sind. Bei dieser bekannten Schleifmaschine sind im übrigen nicht nur das Maschinengestell, sondern auch die Schwingungen aussendenden Teile, wie Spindelstock usw., leicht. Im Gegensatz zu diesen bekannten Schleifmaschinen handelt es sich, bei der Erfindung um leichte und billige Maschinengestelle, einerlei, ob aus Gußeisen oder Blech, in welche Schwingungen gemäß der Erfindung überhaupt nicht gelangen, somit Schwingungsdämpfer überflüssig werden, und die ohne weiteres für Hochleistungsschleifmaschinen brauchbar sind.to There are already grinding machines with a light and cheap type of machine frame known. With these machines, the required rigidity and freedom from vibration of the frame should be achieved in a very specific way Way and shape welded steel sheets can be achieved. In practice, however, it has show that the swings in the machine frame only can be weakened by using specific and additional damping agents can and therefore hardly in such a way that these frames are made of steel for high-performance grinding machines are usable. In this known grinding machine, not only are the machine frame, but also the parts that emit vibrations, such as the headstock, etc., easily. In contrast These known grinding machines are light ones in the invention and cheap machine frames, regardless of whether they are made of cast iron or sheet metal, in which vibrations according to the invention do not arrive at all, thus vibration damper superfluous and which are easily usable for high-performance grinding machines.
Anderseits sind auch schon Schleifmaschinen bekannt, bei denen zur Erzielung eines sauberen und genauen Schliffes die Kraftübertragung von den Schwingungen aussendenden Motoren zum Werkstück und zur Schleifscheibe durch Schwingungen dämpfende Zwischenglieder, wie Riemen, Rohhautzahnräder usw., erfolgt. Die Schwingungen jedoch, welche von den Lagern der Wellen ausgehen, welche die ebenfalls Schwingungen aussendenden Getriebe, wie Zahnräder usw., tragen, können bei diesen Schleifmaschinen ungestört in das Maschinengestell und somit zur Werkstück- und Schleifscheibenlagerung gelangen. Um nun zu verhindern, daß das Gestell selbst durch die von diesen Sendern ausgehenden Schwingungen in Resonanzschwingungen gerät und dadurch die Ausschläge im Gestell noch vergrößert werden, sind bisher bei diesen bekannten Feinstschleifmaschinen die Wände des Gestells erheblich verstärkt worden. Dies aber nicht mit Rücksicht auf Steifigkeit gegenüber den auftretenden statischen Kräften, sondern nur, um die Masse des in Schwingungen geratenen Gestells zu erhöhen und dieses möglichst weit aus dem Resonanzgebiet herauszubekommen.On the other hand, there are already grinding machines known where the power transmission to achieve a clean and precise finish from the motors that emit vibrations to the workpiece and the grinding wheel by means of vibration damping Intermediate links, such as belts, rawhide gears, etc., takes place. The vibrations, however, caused by the bearings of the shafts go out, which also emit vibrations gear such as gear wheels, etc., wear can with these grinding machines undisturbed in the machine frame and thus get to the workpiece and grinding wheel storage. Now to prevent that Frame itself due to the vibrations emanating from these transmitters in resonance vibrations device and thereby the deflections in the frame are increased, So far, the walls of the frame have been significantly reinforced in these known fine grinding machines. But not this with regard to rigidity in relation to the occurring static forces, but only, to increase the mass of the vibrating frame and this as far as possible to get out of the resonance area.
Das Neue und Erfinderische wird nun beim Erfmdungsgegenstand darin gesehen, daß dieWhat is new and inventive is now seen in the subject matter of the invention in that the
