The construction costs and the time necessary for the transport of the workpieces are thus essentially reduced.

Description

Die Erfindung betrifft eine spitzenlose Rundschleifmaschine mit einer Schleifscheibe, einer angenähert achsparallel hierzu angeordneten Regelscheibe und einer dazwischen angeordneten Führungsschiene.The invention relates to a centerless cylindrical grinding machine with a grinding wheel, a regulating wheel arranged approximately axially parallel thereto and a guide rail arranged between them.

Bei spitzenlosen Rundschleifmaschinen sind üblicherweise die Drehachse der Schleifscheibe und die das Werkstück tragende Führungsschiene horizontal angeordnet. Die Drehachse der Regelscheibe ist um einen kleinen Winkel gegenüber der Drehachse der Schleifscheibe schräggestellt, um eine Längsbewegung des Werkstücks zu erreichen. Die Schleifscheibe und/oder die Regelscheibe können Zustellbewegungen ausführen.In centreless cylindrical grinding machines, the axis of rotation of the grinding wheel and the guide rail carrying the workpiece are usually arranged horizontally. The axis of rotation of the regulating wheel is inclined by a small angle with respect to the axis of rotation of the grinding wheel in order to achieve a longitudinal movement of the workpiece. The grinding wheel and / or the regulating wheel can perform feed movements.

Die Zufuhr des zu bearbeitenden Werkstücks erfolgt mittels Zuführeinrichtungen, die im allgemeinen konstruktiv sehr aufwendig sind. Durch die Zuführeinrichtung wird das Werkstück in den Spalt zwischen der Schleifscheibe und der Regelscheibe gebracht. Eine weitere Fördereinrichtung fördert das bearbeitete Werkstück zu einem Magazin oder einem Behälter.The workpiece to be machined is fed by means of feed devices which are generally very complex in terms of construction. The workpiece is brought into the gap between the grinding wheel and the regulating wheel by the feed device. Another conveyor conveys the machined workpiece to a magazine or container.

Aufgabe der Erfindung ist es, eine spitzenlose Rundschleifmaschine der eingangs genannten Gattung so auszubilden, daß der erforderliche Aufwand für das Zuführen und Abführen des Werkstücks wesentlich verringert werden kann.The object of the invention is to design a centerless cylindrical grinding machine of the type mentioned at the outset in such a way that the effort required for feeding and removing the workpiece can be substantially reduced.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Drehachsen der Schleifscheibe und der Regelscheibe und ggf. die Führungsschiene gegenüber der Horizontalen geneigt angeordnet sind. Durch diese Schrägstellung wird erreicht, daß der Transport des Werkstücks im wesentlichen unter der Wirkung der Schwerkraftkomponente erfolgt. Es reicht aus, das Werkstück an einem Ende zwischen die Schleifscheibe und die Regelscheibe einzubringen. Dies kann beispielsweise durch Abgabe des Werkstücks von einer Zuführrutsche geschehen.This object is achieved in that the axes of rotation of the grinding wheel and the regulating wheel and possibly the guide rail are arranged inclined to the horizontal. This inclination ensures that the transport of the workpiece takes place essentially under the action of the gravitational component. It is sufficient to insert the workpiece at one end between the grinding wheel and the regulating wheel. This can be done, for example, by dispensing the workpiece from a feed chute.

Zweckmäßigerweise ist im Verlauf der Führungsschiene ein wegbewegbarer Werkstückanschlag angeordnet, der die Zuführbewegung des Werkstücks vor Beginn des Schleifvorgangs unterbricht.A workpiece stop which can be moved away and which interrupts the feed movement of the workpiece before the grinding process begins is expediently arranged in the course of the guide rail.

Die Neigung der Schleifscheibe, der Regelscheibe und der Führungsschiene können verstellbar sein, um eine Anpassung an unterschiedliche Erfordernisse der Werkstücke zu ermöglichen.The inclination of the grinding wheel, the regulating wheel and the guide rail can be adjustable in order to allow adaptation to different requirements of the workpieces.

Mit der erfindungsgemäßen Schrägstellung der Schleifscheibe und der Regelscheibe werden erhebliche Vorteile beim Laden der Maschine erreicht, weil bereits die Zuführung der Werkstücke in den Schleifspalt weitgehend unter der Schwerkraftwirkung erfolgt. Auch der Transport innerhalb des Schleifspalts ist wesentlich vereinfacht und verbessert, wobei ein wesentlicher Vorteil in der Verringerung der hierfür erforderlichen Zeit und in dem wesentlich geringeren konstrucktiven Aufwand liegt.With the inclined position of the grinding wheel and the regulating wheel according to the invention, considerable advantages are achieved when loading the machine, because the workpieces are already fed into the grinding gap largely under the action of gravity. Transport within the grinding gap is also considerably simplified and improved, with a significant advantage in the reduction in the time required for this and in the substantially lower pressure requirement.

Darüber hinaus bewirkt die Schrägstellung aber auch eine verbesserte Wirkung der beim Schleifen zugegebenen Schleifflüssigkeit, üblicherweise Wasser. Im Gegensatz zu der üblichen horizontalen Anordnung der Scheiben, bei denen das Wasser nur in Umfangsrichtung gefördert wird, ergibt sich durch die Schrägstellung eine zusätzliche Transportwirkung des Wassers in axialer Richtung der Scheiben. Dadurch wird das Wasser gleichmäßiger im Schleifspalt verteilt. Dies führt zu einer Qualitätsverbesserung des Schleifvorgangs.In addition, the inclination also has an improved effect on the grinding liquid, usually water, added during grinding. In contrast to the usual horizontal arrangement of the discs, in which the water is only pumped in the circumferential direction, the inclined position results in an additional transport effect of the water in the axial direction of the disks. As a result, the water is distributed more evenly in the grinding gap. This leads to an improvement in the quality of the grinding process.

Die erfindungsgemäßen Maßnahmen sind gleichermäßen vorteilhaft beim Schleifen im Durchlaufverfahren und beim Einstechverfahren, bei dem mit einer profilierten Schleifscheibe gearbeitet wird.The measures according to the invention are equally advantageous for grinding in the continuous process and in the plunge-in process, in which a profiled grinding wheel is used.

Gemäß einer anderen vorteilhaften Ausführungsform der Erfindung ist vorgesehen, daß ein die Lagerungen der Schleifscheibe und der Regelscheibe tragendes Maschinengestell um eine horizontale, quer zur Drehachse der Schleifscheibe bzw. der Regelscheibe liegende erste horizontale Achse (x) geneigt ist. So kann die erfindungsgemäß gewünschte Neigung der Achsen der Schleifscheibe und der Regelscheibe in konstruktiv sehr einfacher Weise erreicht werden, da keine geneigte oder verstellbare Anordnung der Schleifscheibe und der Regelscheibe am Maschinengestell erforderlich ist.According to another advantageous embodiment of the invention, it is provided that a machine frame supporting the bearings of the grinding wheel and the regulating wheel is inclined about a horizontal first horizontal axis (x) lying transversely to the axis of rotation of the grinding wheel or the regulating wheel. The inclination of the axes of the grinding wheel and the regulating wheel desired according to the invention can thus be achieved in a structurally very simple manner since no inclined or adjustable arrangement of the grinding wheel and the regulating wheel on the machine frame is required.

Weitere vorteilhafte Ausgestaltungen des Erfindungsgedankens sind Gegenstand von weiteren abhängigen Ansprüchen.Further advantageous embodiments of the inventive concept are the subject of further dependent claims.

Die Erfindung wird nachfolgend an Ausführungsbeispielen näher erläutert, die in der Zeichnung dargestellt sind. Es zeigt:

  • Fig. 1 eine stark vereinfachte Draufsicht auf eine spitzenlose Rundschleifmaschine und
  • Fig. 2 einen Schnitt längs der Linie II-II in Fig. 1,
  • Fig. 3 eine Vorderansicht einer anderen Ausführungsform einer spitzenlosen Rundschleifmaschine, die insgesamt um eine erste horizontale Achse geneigt ist, und
  • Fig. 4 eine ähnliche Ansicht wie Fig. 3, wobei die Rundschleifmaschine zusätzlich um eine zweite horizontale Achse geneigt ist.
The invention is explained in more detail below using exemplary embodiments which are illustrated in the drawing. It shows:
  • Fig. 1 is a greatly simplified plan view of a centerless cylindrical grinder and
  • 2 shows a section along the line II-II in FIG. 1,
  • Fig. 3 is a front view of another embodiment of a centerless cylindrical grinding machine which is inclined overall about a first horizontal axis, and
  • Fig. 4 is a view similar to Fig. 3, wherein the cylindrical grinding machine is additionally inclined about a second horizontal axis.

Die in der Zeichnung sehr stark vereinfacht dargestellte spitzenlose Rundschleifmaschine weist ein Maschinengestell 1 auf, in dem ein Träger 2 um eine Schwenkachse 3 schwenkbar gelagert ist. Auf dem Träger 2 sind die Lagerung 4 und der Antrieb 5 für eine Schleifscheibe 6 angeordnet. Eine angenähert achsparallel zur Schleifscheibe 6 angeordnete Regelscheibe 7 ist mit ihrer Lagerung 8 und ihrem Antrieb in der Weise auf dem Träger 2 angeordnet, daß die Regelscheibe 7 um eine horizontale, quer zur Drehachse der Schleifscheibe 6 verlaufende Schwenkachse 9 schwenkbar ist. Die Regelscheibe 7 kann dadurch in üblicher Weise in einem kleinen Winkel relativ zu der Schleifscheibe 6 schräggestellt werden.The centerless cylindrical grinding machine shown in a very simplified form in the drawing has a machine frame 1, in which a carrier 2 is pivotally mounted about a pivot axis 3. The bearing 4 and the drive 5 for a grinding wheel 6 are arranged on the carrier 2. An approximately axially parallel to the grinding wheel 6 arranged regulating wheel 7 is arranged with its bearing 8 and its drive on the carrier 2 in such a way that the regulating wheel 7 can be pivoted about a horizontal pivot axis 9 running transversely to the axis of rotation of the grinding wheel 6. The regulating wheel 7 can thereby be inclined in the usual way at a small angle relative to the grinding wheel 6.

Ein Schwenkantrieb 10, der in Fig. 2 nur schematisch angedeutet ist, ermöglicht eine Schwenkung des Trägers 2 und damit eine Verstellung des Neigungswinkels der Schleifscheibe 6 und der Regelscheibe 7 gegenüber der Horizontalen. Zwischen der Schleifscheibe 6 und der Regelscheibe 7 ist am Träger 2 eine Führungsschiene 11 angebracht, deren obere Führungskante parallel zur Drehachse der Schleifscheibe 6 verläuft und zusammen mit dieser neigbar ist.A swivel drive 10, which is only indicated schematically in FIG. 2, enables the support 2 to be pivoted and thus an adjustment of the angle of inclination of the grinding wheel 6 and the regulating wheel 7 with respect to the horizontal. Between the grinding wheel 6 and the regulating wheel 7, a guide rail 11 is attached to the carrier 2, the upper guide edge of which runs parallel to the axis of rotation of the grinding wheel 6 and can be inclined together with the latter.

Eine Zuführeinrichtung 12 für die zu bearbeitenden Werkstücke 13, beispielsweise Zylinder, besteht beim dargestellten Ausführungsbeispiel in einfachster Form aus einer Rutsche, über die die Werkstücke 13 bis zum Anfang der Führungsschiene 11 in den Spalt zwischen der Schleifscheibe 6 und der Regelscheibe 7 gelangen.A feed device 12 for the workpieces 13 to be machined, for example cylinders, in the illustrated embodiment in the simplest form consists of a slide, via which the workpieces 13 get into the gap between the grinding wheel 6 and the regulating wheel 7 up to the beginning of the guide rail 11.

Im Verlauf der Führungsschiene 11 ist ein Anschlag 14 angeordnet, der beispielsweise nach unten zurückziehbar ist, wie in Fig. 2 mit einem Pfeil angedeutet. Der Anschlag 14 hält das Werkstück 13 an, bevor die Zustellung und Bearbeitung erfolgt. Wenn der Anschlag 14 nach unten gezogen wird, gibt er das Werkstück 13 frei, so daß es unter der Wirkung der Schwerkraft zum anderen Ende der Führungsschiene 11 gelangt. Dort wird das Werkstück von einer Transporteinrichtung 15 übernommen, die beispielsweise wieder eine einfache Rutsche sein kann, auf der das Werkstück 13 bis zu einem Sammelbehälter oder einem Magazin gelangt.In the course of the guide rail 11, a stop 14 is arranged, which can be retracted downward, for example, as indicated by an arrow in FIG. 2. The stop 14 stops the workpiece 13 before the infeed and processing takes place. When the stop 14 is pulled down, it releases the workpiece 13 so that it reaches the other end of the guide rail 11 under the action of gravity. There, the workpiece is taken over by a transport device 15, which can again be a simple slide, for example, on which the workpiece 13 reaches a collecting container or a magazine.

Anstelle einer verstellbaren Ausführung des Trägers 2 kann auch eine feste Anordnung gewählt werden, bei der die Neigung fest vorgegeben ist. Beschrieben wurde die Anwendung der Erfindung beim Durchlaufschleifen. In entsprechend abgewandelter Weise kann aber auch das Einstechschleifen ausgeführt werden. Auch die Werkstückzufuhr und der Abtransport der Werkstücke kann gegenüber dem dargestellten Ausführungsbeispiel wesentlich verändert werden, wobei in jedem Falle die durch die Schrägstellung erzielten Vorteile erhalten bleiben.Instead of an adjustable version of the carrier 2, a fixed arrangement can also be selected in which the inclination is fixed. The use of the invention in continuous grinding has been described. Plunge grinding can also be carried out in a correspondingly modified manner. The workpiece feed and the removal of the workpieces can also be changed significantly compared to the exemplary embodiment shown, the advantages achieved by the inclination being retained in any case.

Fig. 3 zeigt eine andere Ausführungsform einer spitzlenlosen Rundschleifmaschine. Hierbei sind ein die Lagerung 4ʹ der Schleifscheibe 6ʹ bildender Schlitten und ein die Lagerung 8ʹ der Regelscheibe 7ʹ bildender Schlitten auf einem Maschinengestell 1ʹ verfahrbar aufgenommen. Das Maschinengestell 1ʹ ist um eine horizontale, quer zur Drehachse der Schleifscheibe 6ʹ bzw. der Regelscheibe 7ʹ liegende horizontale Achse x geneigt. In Fig. 3 ist eine Neigung zur Maschinenvorderseite hin dargestellt; stattdessen kann die Neigung auch zur gegenüberliegenden Maschinenrückseite erfolgen. Die Neigungsrichtung wird nach den jeweils durchzuführenden Schleifarbeiten und/oder danach ausgewählt, in welcher Weise und an welcher Seite das Beladen der Schleifmaschine mit den Werkstücken erfolgt.Fig. 3 shows another embodiment of a centerless grinding machine. Here, a carriage forming the bearing 4ʹ of the grinding wheel 6ʹ and a carriage forming the bearing 8ʹ of the regulating wheel 7ʹ are movably received on a machine frame 1ʹ. The machine frame 1ʹ is one horizontal horizontal axis x inclined to the axis of rotation of the grinding wheel 6 Schleif or the regulating wheel 7ʹ. 3 shows an inclination towards the front of the machine; instead, it can also be inclined to the opposite rear of the machine. The direction of inclination is selected according to the grinding work to be carried out and / or according to how and on which side the grinding machine is loaded with the workpieces.

In Fig. 4 ist die gleiche spitzenlose Rundschleifmaschine wie in Fig. 3 gezeigt, jedoch ist hierbei das Maschinengestell 1ʹ nicht nur um die erste horizontale Achse x, sondern zusätlich auch um eine rechtwinklig zur Achse x verlaufende zweite horizontale Achse z geneigt. Die Neigung um diese Achse z ist zur Regelscheibe 7ʹ hin gerichtet.4 shows the same centerless cylindrical grinding machine as shown in FIG. 3, but here the machine frame 1ʹ is not only inclined about the first horizontal axis x, but additionally also about a second horizontal axis z running at right angles to the axis x. The inclination about this axis z is directed towards the regulating wheel 7ʹ.

Mit den Neigung der gesamten Rundschleifmaschine um die Achse x wird die bereits im Zusammenhang mit der Ausführungsform nach den Fig. 1 und 2 erläuterte Wirkung erreicht, daß nämlich insbesondere ein vereinfachter Transport der Werkstücke unter Schwerkrafteinfluß ermöglicht wird. In Kombination mit dieser Neigung um die Achse x ergibt die zusätzliche Neigung um die Achse z ein verbessertes physikalisches Verhalten des Werkstücks im Schleifspalt auf der Führungsschiene, was zu höheren Genauigkeiten sowohl hinsichtlich der Rundheit als auch hinsichtlich der Zylindrizität führt. Außerdem läßt sich damit eine gesteigerte Oberflächenqualität des Werkstücks erreichen.With the inclination of the entire cylindrical grinding machine about the axis x, the effect already explained in connection with the embodiment according to FIGS. 1 and 2 is achieved, namely that in particular a simplified transport of the workpieces under the influence of gravity is made possible. In combination with this inclination around the axis x, the additional inclination around the axis z results in an improved physical behavior of the workpiece in the grinding gap on the guide rail, which leads to higher accuracies both in terms of roundness and in terms of cylindricity. In addition, an increased surface quality of the workpiece can be achieved.
