Description
Die Erfindung betrifft eine Vorrichtung zum spitzenlosen Schleifen und Polieren von ringförmigen Körpern, wie z. B. Fahrradfelgen, Topf ränder 'oder sonstiger Reifen, mit Außen- und Innenbearbeitung, wobei das Werkstück zwischen zwei timlaufenden, mit der profilierten UmfLäche wirkenden Scheiben, von denen eine im Innenraum des Ringes angeordnet ist, mittels mehrerer an seinem Umfange angreifender Rollen gehalten wird. Um die in den. meisten Fällen profilierten Bearbeitungsflächen des Ringes durch die Arbeitsscheibe weitgehend zu erfassen, ist es erforderlich, ■ daß das Werkstück eine Schwenkbewegung· ausführen kann. Je nach der Form des Reifenprofils ist dabei weiterhin eine bestimmte Schräglage zu den Scheibenebenen von Nutzen, die auch während der Schwenkbewegung des Werk-Stückes eingehalten werden muß.The invention relates to a device for centerless grinding and polishing of annular bodies, such as. B. bicycle rims, pot rims' or other tires, with external and internal machining, with the workpiece between two timers, with the profiled periphery acting panes, one of which in the interior of the Ring is arranged, held by means of several acting on its circumference roles will. To get those in the. In most cases, the working disk largely covers the profiled machining surfaces of the ring, it is necessary that the workpiece can swivel. Depending on the shape of the tire profile, there is still a certain incline the disk planes are useful, even during the pivoting movement of the work piece must be adhered to.
Gemäß der Erfindung ist der mit den Tragrollen für das Werkstück ausgerüstete Halter so ausgebildet, daß er um eine Achse schwenkbar ist, die die beiden Drehachsen der Arbeitsscheiben senkrecht kreuzt, und zwar annähernd senkrecht, da in den meisten Fällen die Arbeitsscheiben um einen geringen Betrag gegenseitig verwinkelt sind. Die Schwenkachse geht dabei durch die Berührungsstelle der beiden Arbeitsscheiben oder durch die Bearbeitungszone.According to the invention is equipped with the support rollers for the workpiece Holder designed so that it is pivotable about an axis which the two axes of rotation of the working disks crosses vertically, and almost vertically, as in most of them Cases the working disks are mutually angled by a small amount. the The pivot axis goes through the point of contact of the two working disks or through the processing zone.
Ein weiteres Merkmal der Erfindung ist die verstellbare Anordnung der Werkstückhalterollen am schwenkbaren Werkstückhalter, wodurch jede erforderliche Schräglage, je nach, dem Profil des Werkstücks, zu den Arbeitsscheiben eingestellt werden kann. Another feature of the invention is the adjustable arrangement of the workpiece holding rollers on the swiveling workpiece holder, whereby any required inclination, depending on the profile of the workpiece can be adjusted to the working disks.
Die Zeichnung zeigt eine Ausführungsform des Erfindungsgegenstandes in Abb. ι in einer Seitenansicht und in Abb. 2 in einer Stirnansicht.The drawing shows an embodiment of the subject matter of the invention in FIG Fig. Ι in a side view and in Fig. 2 in a front view.
Abb. 3 veranschaulicht in schematischer Darstellung die zulässige Schwenkbewegung des Werkstückträgers, in Richtung der Schwenkachse, gesehen.Fig. 3 shows a schematic representation of the permissible pivoting movement of the workpiece carrier, seen in the direction of the pivot axis.
Die Lage des Werkstückes α wird durch die an seinem Umfang angeordneten Halterollen δ, δ' und durch die beiden profilierten Arbeitsscheiben c, d, die das Werkstück in bekannter Weise, infolge ihrer verschiedenen Umfangsgeschwindigkeiten zwischen sich hindurch fördern, bestimmt. Je nach dem Profil des Werkstückes kann dieses, wie Abb. 2 erkennen läßt, dabei eine Schräglage zu den Arbeitsscheiben einnehmen.The position of the workpiece α is determined by the holding rollers δ, δ 'arranged on its circumference and by the two profiled working disks c, d, which convey the workpiece in a known manner due to their different circumferential speeds between them. Depending on the profile of the workpiece, as shown in Fig. 2, it can assume an inclined position in relation to the working disks.
Am Maschinenkörper/ ist der Werkstückträger g angelenkt. Die Drehachse ist durch eine strichpunktierte Linie A, die die Achsen der beiden Arbeitsscheiben c, d in der Bearbeitungszone annähernd senkrecht kreuzt, angedeutet. Durch die verstellbare Anordnung der Halterollen b, b' an dem Träger g kann die Schräglage des Werkstückes a, je nach seinem Profil, zu den Arbeitsscheiben genau eingestellt werden. The workpiece carrier g is articulated on the machine body /. The axis of rotation is indicated by a dash-dotted line A, which crosses the axes of the two working disks c, d in the machining zone approximately perpendicularly. Due to the adjustable arrangement of the holding rollers b, b ' on the carrier g , the inclined position of the workpiece a, depending on its profile, can be precisely adjusted to the working disks.
In dieser eingestellten Schräglage kann das Werkstück die in der Abb. 3 angedeutete Schwenkbewegung ausführen.In this set inclined position, the workpiece can take the position indicated in Fig. 3 Perform swivel movement.
Das Ein- und Ausheben des Werkstückes in bzw. aus seiner Arbeitslage erfolgt in bekannter Weise durch die gegenseitige Entfernung der beiden Arbeitsscheiben voneinander, wobei eine der beiden Scheiben mit einem Winkelhebel/ verbunden sein kann, der _durch Betätigung eines Fußhebels k die achsensenkrechte Verschiebung der Scheibe^ bewirkt.The switching on and lifting of the workpiece into or out of its working position in a known manner by the mutual distance between the two working wheels from each other, one of said two disks having a crank levers may be connected /, the _Due actuation of a foot lever k is the axis-perpendicular displacement of the disc ^ causes.
Durch ein Gegengewicht/n kann die nachgiebige Anpressung der Arbeitsscheibe bzw. Förderscheibe an das Werkstück selbsttätig erfolgen.The flexible Automatic pressing of the working disk or conveyor disk onto the workpiece take place.
