Description

Maschine zum Ballig- und Hohlschleifen von Walzen Den Gegenstand der Erfindung bildet eine Maschine zum Ballig- und Hohlschleifen von Walzen, bei der die Schleifscheibe auf ihrem Wege längs des Werkstückes durch Schwingen des Schleifscheibensupportes um eine unterhalb der Schleifspindel liegende Achsemittels eines verstellbaren Kurbelgetriebes bei- und abgestellt wird.Machine for crowning and hollow grinding of rolls The subject of the Invention forms a machine for crowning and hollow grinding of rolls, in which the grinding wheel on its way along the workpiece by swinging the grinding wheel support around an axis of an adjustable crank mechanism located below the grinding spindle is added and removed.

Von den bekannten Ausführungen dieser Art unterscheidet sich der Gegenstand dadurch, daß das Kurbelgetriebe aus einer mittels Exzenters o. dgl. in Schwingung versetzten Gleitschiene für einen in der Längsrichtung verschiebbaren Anschlag am schwingenden Ende des Spindelsupportes besteht, um durch Vermeidung von Gelenken die Präzision der Beistellbewegung zu erhöhen.The subject differs from the known designs of this type in that the crank mechanism consists of an eccentric or the like in vibration offset slide rail for a longitudinally displaceable stop on The swinging end of the spindle support consists in order to avoid joints to increase the precision of the positioning movement.

In der Zeichnung ist ein Ausführungsbeispiel in Schnitt-Seitenansicht dargestellt. Der Bettschlitten H, der auf dem Schleifbett, senkrecht zur Zeichenebene, hin und her bewegt wird, trägt den um den Bolzen F schwenkbar gelagerten SchleifschlittenträgerE. Am BettschlittenH ist eine SchwingeB im Punkt C drehbar gelagert und liegt mit ihrem anderen Ende auf einem Exzenter A. Letzteres wird während der Hin- und Herbewegung des Schleifschlittens H gedreht und erteilt hierdurch dem Schleifschlittenträger E mittels der Schwinge B und des Auflagers D eine Schwingbewegung in Abhängigkeit von der Längsbewegung des Schleifschlittens, so daß die Achse K der Schleifscheibe M in der Pfeilrichtung pendelt und sich dadurch der Werkstückachse nähert und von ihr entfernt, was die Schleifkurve ergibt. Durch Verstellung des Auflagepunktes D mittels des Schiebers T durch das Handrad G kann bei gleichbleibender Schwingung der Schwinge B dem Schleifschlittenträger F_ eine beliebige Schwingbewegung erteilt werden, die wiederum die Schleifkurvenhöhe bestimmt.In the drawing, an exemplary embodiment is shown in a sectional side view. The bed slide H, which is moved back and forth on the grinding bed, perpendicular to the plane of the drawing, carries the grinding slide carrier E, which is pivotably mounted about the bolt F. A rocker arm B is rotatably mounted at point C on the bed slide H and its other end rests on an eccentric A. The latter is rotated during the back and forth movement of the grinding slide H and thereby gives the grinding slide carrier E an oscillating movement by means of the rocker arm B and the support D. Depending on the longitudinal movement of the grinding carriage, so that the axis K of the grinding wheel M oscillates in the direction of the arrow and thereby approaches the workpiece axis and moves away from it, which results in the grinding curve. By adjusting the support point D by means of the slide T with the handwheel G, with constant oscillation of the rocker arm B, the grinding carriage carrier F_ can be given any oscillating movement, which in turn determines the grinding curve height.

Die Schleifkurve kann an Hand einer Tabelle genau eingestellt werden.The grinding curve can be precisely set using a table.

Statt des Exzenters nebst Schwinge kann natürlich auch jeder andere Antrieb verwendet werden und statt der beschriebenen Hebelverstellung auch jede andere verstellbare Übertragung.Instead of the eccentric and swing arm, anyone else can, of course Drive can be used and instead of the lever adjustment described, each other adjustable transmission.

Auch könnte man mehrere Exzenter o. dgl. ähnlich einer Stufenscheibe hintereinander anordnen oder statt des Exzenters eine aus vielen Exzenterprofilen hintereinander bestehende Trommelkurve verwenden und die Schwinge entsprechend längs der Exzenterwelle verstellen.One could also use several eccentrics or the like, similar to a stepped disk arrange one behind the other or instead of the eccentric one of many eccentric profiles Use a drum cam that exists one behind the other and the rocker arm lengthways accordingly adjust the eccentric shaft.
