Die Erfindung betrifft ein Verfahren zum Rundschleifen eines Werkstücks, bei dem eine sich drehende Schleifscheibe gegen eine zu schleifende Fläche des Werkstücks zugestellt wird, während sich gleichzeitig das Werkstück um seine Längsachse dreht, wobei die zu schleifende Fläche von einer Kante begrenzt wird und in eine Nachbarfläche übergeht. Die Erfindung betrifft auch eine Vomchtung zum Rundschleifen eines Werkstücks, mit einer Schleifscheibe und einer Aufnahme für das zu schleifende Werkstuck. Solche Verfahren und Vorrichtung sind aus CH 628 560 A bekannt.The invention relates to a method for cylindrical grinding of a workpiece, in a rotating grinding wheel against a surface to be ground of Workpiece is delivered while at the same time the workpiece is around Rotates longitudinal axis, wherein the surface to be grounded bounded by an edge becomes and goes into a neighboring area. The invention also relates to a Vomchtung for cylindrical grinding of a workpiece, with a grinding wheel and a receptacle for the workpiece to be ground. Such methods and apparatus are known from CH 628 560 A.
Während des Schleifvorgangs entsteht ein Grat, der von der zu schleifenden Fläche ausgeht und sich über die Kante hinaus zur angrenzenden Nachbarfläche des Werkstücks hin erstreckt. Wenn dieser Grat für die spätere Funktion des fertig bearbeiteten Werkstücks störend ist, muß er durch einen separaten Entgratvorgang entfernt werden.During the grinding process, a burr is created, which differs from the one to be sanded Surface goes out and beyond the edge to the adjacent Neighboring surface of the workpiece extends. If this ridge for the future Function of the finished workpiece is disturbing, he must by a separate deburring be removed.
Aus der CH 628 560 A ist eine Vorrichtung zum Rundschleifen eines Werkstücks mit einer Schleifscheibe und einer Aufnahme für das zu schleifende Werkstück bekannt. Eine Werkstückabstützvorrichtung sorgt dafür, daß Maßfehler, die aus der Durchbiegung des Werkstücks bei der Bearbeitung durch die Schleifscheibe resultieren, wennieden werden. Hierzu wird eine gegenüber der Schleifscheibe angeordnete, hydraulisch betätigte Stützbacke auf das Werkstück gedrückt, deren Anpreßkraft von einer regelbaren Druckkammer bereitgestellt wird.The CH 628 560 A is a device for cylindrical grinding a workpiece with a grinding wheel and a receptacle known for the workpiece to be ground. A workpiece support device makes sure that dimensional errors from the Deflection of the workpiece during processing by the Grinding wheel results when used. For this purpose is a arranged opposite the grinding wheel, hydraulic pressed support jaw pressed on the workpiece, its contact pressure provided by a controllable pressure chamber.
Die Aufgabe der Erfindung besteht darin, das Schleifverfahren der eingangs genannten Art dahingehend zu verbessern, daß der Entgratvorgang entfallen kann. Die Aufgabe der Erfindung besteht weiterhin darin, eine Vorrichtung zum Schleifen zu schaffen, die es ermöglicht, auf den separaten Entgratvorgang zu verzichten. The object of the invention is the grinding process of the above mentioned type to improve that the deburring omitted can. The object of the invention further consists in a device for To create grinding, which allows to the separate deburring process too without.
Das erfindungsgemäße Verfahren mit den Merkmalen des Patentanspruchs 1 hat den Vorteil, daß der beim Zustellen der Schleifscheibe gegen die zu schleifende Fläche entstehende Grat automatisch beseitigt wird. Ein separater Entgratvorgang ist somit nicht mehr notwendig.The inventive method with the features of claim 1 has the advantage that when delivering the grinding wheel against the Grinding surface resulting burr is automatically removed. A separate one Deburring process is therefore no longer necessary.
Gemäß einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß der Entgratdorn so eingestellt wird, daß er über die Nachbarfläche und die Kante zur zu schleifenden Fläche hin nach außen übersteht. Bei dieser Ausrichtung des Entgratdornes wird gewährleistet, daß der beim Schleifen entstehende Grat wieder vollständig auf die zu schleifende Fläche zurückgedrückt werden kann.According to a preferred embodiment of the invention it is provided that the deburring mandrel is adjusted so that it over the neighboring surface and the Edge protrudes outward to the surface to be ground.

In Fig. 1 ist eine Maschine gemäß einer ersten Ausführungsform der Erfindung
gezeigt. Die Schleifmaschine enthält einen Rahmen 10, in welchem eine
Aufnahme 12 für ein zu bearbeitendes Werkstück 14 angeordnet ist. Es ist ein
Antrieb 16 vorgesehen, mit dem das Werkstück 14 in Drehung versetzt werden
kann. Weiterhin ist eine Schleifscheibe 18 vorgesehen, die mittels eines
Zustellantriebes 20 sowohl in Drehung versetzt werden kann als auch geeignet
gegen eine zu schleifende Fläche des Werkstücks 14 zugestellt werden kann.
Die bis hierhin beschriebene Schleifmaschine ist von herkömmlichem Aufbau,
so daß ihre Konstruktion nicht im Detail beschrieben werden braucht.In Fig. 1 is a machine according to a first embodiment of the invention
shown. The grinding machine includes a
Die Schleifmaschine ist zusätzlich mit einem Entgratdorn 22 versehen, der aus
Hartmetall besteht und von einem Andruckmechanismus 24 gegen das zu
bearbeitende Werkstück 14 gedrückt werden kann. Der Andruckmechanismus
weist einen Pneumatikzylinder 26 (siehe Fig. 2) auf, dessen Innenraum über
zwei schematisch dargestellte Pneumatikleitungen 28 mit Druck beaufschlagt
werden kann, um den Entgratdorn 22 in der Richtung des Pfeils P von Fig. 2
gegen das Werkstück 14 zu drücken.The grinding machine is additionally provided with a
Die Wirkungsweise des Entgratdorns ist die folgende: Wenn die Schleifscheibe
18 gegen eine zu schleifende Fläche 30 des Werkstücks 14 in der Richtung
des Pfeils Z von Fig. 2 zugestellt wird, entsteht ein Grat 32 (siehe die Figuren 3
und 4), der aus Material besteht, das über eine Kante 34, welche die zu
bearbeitende Fläche 30 des Werkstückes begrenzt, auf eine sich anschließende
Nachbarfläche 36 verdrängt wird.The operation of the deburring mandrel is the following: If the
Da sich das Werkstück 14 dreht, gelangt der Grat zum Entgratdorn 22, der bei
der gezeigten Ausführungsform etwa gegenüber der Schleifscheibe 18 angeordnet
ist. Dort wird der Grat von der Stirnfläche des Entgratdorns 22, die als
ebene Andruckfläche 38 ausgebildet ist, sich senkrecht zur Längsachse des
Entgratdornes erstreckt und über die Kante 34 hinausragt, auf die zu
schleifende Fläche 30 zurückgedrückt. Dies ist deutlich durch Vergleich der
Figuren 4 und 5 zu sehen. Fig. 4 zeigt einen Schnitt durch einen Abschnitt des
Werkstückes, der gerade von der Schleifscheibe 18 bearbeitet wurde und sich
nun hin zum Entgratdorn 22 dreht. Der Grat 32 befindet sich außerhalb der zu
bearbeitenden Fläche 30 im Bereich der an die Kante 34 angrenzenden
Nachbarfläche 36. In Fig. 5 ist ein Schnitt durch einen Abschnitt des
Werkstückes zu sehen, der sich nach der Berührung mit der Stirnfläche des
Entgratdornes 22 wieder hin zur Schleifscheibe 18 bewegt. Es ist deutlich zu
sehen, daß der Grat 32 zurück auf die zu bearbeitende Fläche 30 gedrückt
wurde, so daß er beim nächsten Kontakt mit der Schleifscheibe 18
abgeschliffen wird.As the
Die Andruckkraft des Entgratdorns 22 kann in Abhängigkeit von den jeweiligen
Anforderungen und dem zu bearbeitendem Material gewählt werden. Wenn
das Werkstück 14 beispielsweise eine Ventilnadel für ein Kraftstoff-Einspntzventil
für Verbrennungskraftmaschinen ist, bei der die zu bearbeitende Fläche
einen Durchmesser von wenigen Millimetern hat, sind Andruckkräfte von 50 N
ausreichend.The pressing force of the
Der hier beschriebene Kreislauf des Erzeugens des Grates durch Berührung
zwischen dem Werkstück 14 und der Schleifscheibe 18, des Zurückdrückens
des Grates 32 auf die zu bearbeitende Fläche 30 und des Abschleifens des
Grates wiederholt sich so lange, bis die Schleifscheibe ausfeuert, also keinerlei
Material mehr abgetragen wird und folglich auch kein Grat entstehen kann. Das
Ergebnis des beschriebenen Schleifvorganges ist ein Werkstück 14 mit
geschliffener Fläche 30, die keinen Grat aufweist, ohne daß ein separater
Entgratvorgang erforderlich war. The circuit described here of creating the ridge by touch
between the
Die hier gezeigte Anordnung des Entgratdorns 22 relativ zur Schleifscheibe 18
kann je nach den Anforderungen variiert werden. Wenn mehrere Flächen
gleichzeitig geschliffen werden und zusätzlich beispielsweise Meßwerkzeuge
den Schleifvorgang überwachen, kann der Entgratdorn 22 auch in anderen
Stellungen relativ zur Schleifscheibe eingesetzt werden.The arrangement shown here of the
In den Figuren 6 bis 8 ist eine zweite Ausführungsform der Schleifmaschine sowie des damit ausgeführten Schleifverfahrens gezeigt. Für die von der ersten Ausführungsform bereits bekannten Bauteile werden dieselben Bezugszeichen verwendet, und es wird auf die obigen Erläuterungen verwiesen.FIGS. 6 to 8 show a second embodiment of the grinding machine and the grinding process performed therewith. For those of the first Embodiment already known components are the same reference numerals is used, and it is referred to the above explanations.
Der wesentlichste Unterschied zur ersten Ausführungsform besteht darin, daß
hier eine zylindnsche Außenfläche des Werkstücks 14 geschliffen wird, so daß
der Grat 32 auf einer an die zu bearbeitende Fläche 30 angrenzenden
Nachbarfläche 36 entsteht, die sich senkrecht zur Längsachse des Werkstücks
14 erstreckt. Von dieser Nachbarfläche 36 wird der Grat 32 vom Entgratdorn 22
wieder auf die zu schleifende Fläche 30 zurückgedrückt, wie durch Vergleich
der Figuren 7 und 8 zu sehen ist.The most significant difference from the first embodiment is that
here a cylindrical outer surface of the
Im Unterschied zur ersten Ausführungsform liegt der Entgratdorn 22 bei der
zweiten Ausführungsform nicht mit seiner Stirnfläche am Werkstück 14 an,
sondern mit einer konisch ausgebildeten Andruckfläche 38. Außerdem ist die
Längsachse des Entgratdorns 22 nicht senkrecht zur Längsachse des Werkstücks
14 ausgerichtet, sondern erstreckt sich schräg zu dieser. Besonders
erwähnenswert ist, daß der Entgratdorn 22 nicht etwa in der Richtung gegen
das Werkstück 14 gedrückt wird, in die der Grat 32 auf die zu bearbeitende
Fläche zurückgedrückt werden soll, sondern in einer Richtung, in der man
erwarten würde, daß der Grat weiter zur Längsachse des Werkstücks hin nach
innen gedrückt würde. Tatsächlich wird aber der Grat 32 durch die schräg
angestellte Andruckfläche 38 von der Längsachse des Werkstücks 14 weg
zurück auf die zu schleifende Fläche 30 gedrückt. Die hier gezeigte
Ausrichtung des Entgratdorns 22 ist besonders vorteilhaft, wenn in dem
bezüglich Fig. 6 links des Entgratdorns 22 liegenden Bereich andere Bauteile
der Schleifmaschine angeordnet werde müssen; bei dieser Anordnung kann
dann der Andruckmechanismus 24 weit außerhalb dieses Bereichs angeordnet
werden.In contrast to the first embodiment, the deburring
