Description
Vorrichtung zum Grob-, Fein- und Polier-Schleifen von Spiegelscheiben und ähnlichen Gegenständen. Die Erfindung bezieht sich auf eine Vorrichtung zum Grob-, Feinschleifen und Polieren von Spiegels-oheiben und ;ähnlichen Gegenständen unter Verwendung einer großen Anzahl von in mehrere Gruppen. unterteilten Schleifscheiben, wobei jede Gruppe in je einein Zwisc"he' nträger gelagert ist, der &n einem fest oder beweglich angeordneten Hauptträger sitzt und um eine senkrecht zur ArbbeftsflÄche gelegene Achse drehbar ist.Device for coarse, fine and polishing grinding of mirror panes and similar items. The invention relates to a device for Coarse, fine grinding and polishing of mirror surfaces and similar objects using a large number of in multiple groups. divided grinding wheels, each group being stored in one intermediate carrier, the one Fixed or moveable main beam sits and around a perpendicular to the work surface located axis is rotatable.
Die Vorrichtung arbeitet hierbei nach denn Prinzip, daß die Bahnen, die von dem. einzelnm Schleifscheiben beschrieben. werden, sich überschmeidm. Es sind in dieser Beziehung bereits Vorrichtungen bekannt geworden, bei denen die Achten der Schleifscheiben im Zwisntxtäger, und zwar in gleicher Entfernung von dessen Drehachse, angeordnet sind. Diese Finmrichitung benutzt besonders wirksam die Arbeitsweise .der drehbarem, Schleifscheiben, die entweder unmittelbar angetrieben werden oder freibeweglich in: ihrem Träger gelagert sind und gewöhnlich als Arbeitselemente verwendet den.The device works on the principle that the tracks, those of that. individually described in grinding wheels. become overwhelmed. It devices have already become known in this regard in which the figure eight of the grinding wheels in the Zwisntxtäger, at the same distance from it Axis of rotation, are arranged. This Finmrichitung makes particularly effective use of the operation .the rotatable, grinding wheels that are either directly driven or freely movable in: their carrier are stored and usually as work elements uses the.
Es sich! nun aber nicht vermeiden, daß mit Hilfe von Vorrichtungen dieser Art sich Straßen bilden, da .sämtliche Schleifscheiben derselben Gruppe infolge ihrer symmetrischen Anordnung zur Dreihachse stets die gleichen Bahnen durchlaufen.It is! but now do not avoid that with the help of devices roads are formed in this way because all grinding wheels of the same group result their symmetrical arrangement to the axis of three axes always pass through the same paths.
Gemäß der Erfindung werden nun diese Nachteile dadurch beseitigt, daß die Achsen der Schleifscheiben. im wesentlichen gemäß einer Spirale um die Drehachsen der Zwxschenträg er herum angeordnet und drehbar in den Zwischenträgern gelagert sind. Infolge dieser neuen Anordnung beschreiben die einzelnen Punkte jeder Schleifscheibe Kurven, und die einzelnen `Piuhkte-der Schleifscheiben einer Gruppe oder mehrerer benachbarter Gruppen, überschneiden sich unregelmäßig beim Durchlaufen ihrer Babh, so, daß eine Straßenbildung vollkommen ausgeschlossen ist, das Werkstück vielmehr absolut plan- und. gleichmäßig geschliffen wird.According to the invention, these disadvantages are now eliminated by that the axes of the grinding wheels. essentially according to a spiral around the axes of rotation the intermediate carrier is arranged around and rotatably mounted in the intermediate carriers are. As a result of this new arrangement, the individual points describe each grinding wheel Curves, and the individual `` piuhkte '' of the grinding wheels of a group or several neighboring groups, overlap irregularly when passing through their babh, so that a road formation is completely excluded, rather the workpiece absolutely flat and. is sanded evenly.
Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt, und zwar zeigen: Abb. i eine Schleif- und Poliermaschine von vorn gesehen und Abb. z den Schnitt gemäß -x-x 'der Abb. i. Mit i ist der bewegliche Tiscb`bezeichnet, auf deni-@die zu schlefende#bzw. zu polierende Glasscheibe a ruht.The drawing shows an embodiment of the subject matter of the invention shown, namely: Fig. i A grinding and polishing machine seen from the front and Fig. Z the section according to -x-x 'of Fig. I. With i is the movable one Tiscb`, on deni- @ the # or. Glass pane a to be polished is at rest.
Die Arbeitsgeräte bestehen, wie die Zeichnung erkennen läßt, aus Gruppen von beispielsweise je drei Polier- oder Schleifsch@i;-ben 3, die gruppenweise in Zwischenträgern 7 gelagert sind.As the drawing shows, the tools consist of groups of, for example, three polishing or grinding wheels 3, which are grouped in Intermediate carriers 7 are stored.
Die letzteren, sind ihrerseits im Hauptträger gelagert und erhalten durch ihre Achsen 8 Drehbewegungen im Sinne der Pfeile gemäß der Abb. z.The latter are in turn stored and preserved in the main girder through their axes 8 rotational movements in the direction of the arrows according to the Fig. z.
Der Antrieb der Achsen 8 im Träger q, kann ein beliebiger sein.The drive of the axles 8 in the carrier q can be any.
Die Achsen 9 der Polier- oder Schleifscheiben 3 sind in verschiedenen Entfernungen von der Achse 8 der Zwischenträger angeordnet, beispielsweise so, daß sie spiralförmig um die Achse 8 gelagert sind.The axes 9 of the polishing or grinding wheels 3 are different Arranged distances from the axis 8 of the intermediate carrier, for example so that they are mounted in a spiral around the axis 8.
Die Polierscheiben. 3 können freibeweglich in den Zwischenträgern 7 gelagert sein, dergestalt, da.ß sie sieh um ihre Achsen infolge der Bewegung der Zwischenträger und der Reibung gegenüber der Arbeitsfläche in verschiedenem Sinne drehen.The polishing pads. 3 can move freely in the intermediate carriers 7, in such a way that they see about their axes as a result of the movement of the Intermediate carrier and the friction against the work surface in different senses turn.
Es ist aber auch möglich, die Achsen 9 der Polierscheiben. 3 besonders anzutreiben, so daß sie beispielsweise eine Planetbew@egung um die Dwehächse 8 jedes Zwischenträgers 7 ausfühmen, um dadurch zu erreichen, daß die Bahnen der einzelnen Punkte der Polierscheiben einer Gruppe sich auch relativ zw ihrem Zwischenträger gegenseitig überschneiden.But it is also possible to use the axes 9 of the polishing disks. 3 special to drive, so that they, for example, a planetary movement around the Dwehächse 8 each Execute intermediate carrier 7 in order to achieve that the paths of the individual Points of the polishing pads of a group are also relatively between their intermediate carrier overlap each other.
Auf jeden Fall wird die ganze zu schleifende und zu polierende Fläche von den Schleifscheiben, so bearbeitet, daß die von den einzelnen Punkten des Umfanges jeder Scheibe beschriebenen Bahnen, sich gegenseitig überschneiden; infolgedessen also zwischen den einzelnen Schleifscheiben die Bildung von Straßen oder ähnlichen Unebenheiten ausgeschlossen ist, da sich alle Flächen. partiell und ebenso wiederum die Gruppen untereinander überscheiden.In any case, the entire surface to be sanded and polished will be of the grinding wheels, machined so that those of the individual points of the circumference paths described on each disc, mutually overlap; Consequently thus the formation of roads or similar between the individual grinding wheels Unevenness is excluded, since all surfaces. partially and also in turn the groups differ from each other.
