Abstract

The apparatus for polishing a workpiece (7) has an open-topped cylindrical work holder (4) rotated about a vertical axis by a drive motor (20) below. Supported on a surface (1) around the work holder is a block (8) with an extension (9), which closes the open top of the holder, forming a chamber which is filled with a polishing medium. The block is hollow, and is divided into two chambers (11,12) by a vertical partition (10). Inside each chamber is a piston (14,15) so connected to respective drive motors (16,17) that they are reciprocated alternately. Below the partition is an extension (13), past which the polishing medium is driven in opposite directions over the workpiece below.

Description

Vorrichtung zum Polieren der Oberfläche eines Device for polishing the surface of a

in einer Halterung eingespannten Werkstücks Gegenstand der Erfindung ist eine Vorrichtung zum Polieren der Oberfläche eines in einer Halterung eingespannten Werkstücks mittels einer an der Werkstückoberfläche entlanggeführten Poliermasse, die an der Werkstückoberfläche in einer Kammer mittels gegenläufig verstellter, auf die Poliermasse einwirkender Preßstempel im Hin- und Rückhub bewegt wird, bestehend aus einer Werkstückaufnahme, einer die zu polierende Oberfläche des Werkstücks einschließenden Kammer und zwei an Kammerwandungen angeschlossene Preßstempel, bei der die Preßstempel motorisch mittels Stellmotoren verstellbar sind. The invention relates to the workpiece clamped in a holder is a device for polishing the surface of a clamped in a holder Workpiece by means of a polishing compound guided along the workpiece surface, which on the workpiece surface in a chamber by means of oppositely adjusted, the ram acting on the polishing compound is moved in a back and forth stroke, consisting from a workpiece holder, one enclosing the surface of the workpiece to be polished Chamber and two press rams connected to the chamber walls, in which the press ram are adjustable by means of servomotors.

Vorrichtungen dieser Art sind zum Polieren der Innenwandungen zweiseitig offener und hohler Werkstücke an sich bekannt. Es ist auch bekannt, die Werkstückoberfläche dadurch zu polieren, daß in einer Kammer mittels gegenläufig verstellter, auf die Poliermasse einwirkender Preßstempel im Hin- und Rückhub bewegt wird.Devices of this type are two-sided for polishing the inner walls open and hollow workpieces known per se. It is also known the workpiece surface to polish in that in a chamber by means of counter-adjusted, on the Polishing compound acting press ram is moved back and forth.

Die Erfindung befaßt sich mit der Ausbildung einer Vorrichtung dieser Art, die zum Polieren von Werkstückoberflächen benutzbar ist, die keinen Hohlraum einschließen und eine offene Oberfläche eines Werkstücks bilden.The invention is concerned with the formation of an apparatus for this Type that can be used for polishing workpiece surfaces, the do not include a cavity and form an open surface of a workpiece.

Erfindungsgemäß wird dazu vorgeschlagen, die Ausbildung derart zu treffen, daß die Kammer durch Wandungen der ein Gefäß bildenden Werkstückaufnahme und einen Deckel gebildet ist, der mit euter Trennwand in das Gefäß hineinragt, die das Gefäß in zwei Teilkammern teilt und daß die Preßstempel am Deckel beiderseits der Trennwand angeordnet sind.According to the invention it is proposed to the training in such a way meet that the chamber through walls of the workpiece holder forming a vessel and a lid is formed which protrudes with a partition wall into the vessel, which divides the vessel into two sub-chambers and that the ram on both sides of the lid the partition are arranged.

Zweckmäßig ist die Ausbildung derart getroffen, daß das Gefäß auf einem Tisch gegen den Deckel mittels eines Antriebsmotors drehbar gelagert ist.Appropriately, the training is made such that the vessel on a table is rotatably mounted against the cover by means of a drive motor.

Die anliegende Zeichnung erläutert ein bevorzugtes Ausführungsbeispiel.The attached drawing explains a preferred embodiment.

In des Darstellung bezeichnen 1 eine Tischplatte, die in einer Führung 2 eine um eine Achse 3 drehbar gelagerte Werkstückhalterung 4 aufnimmt. Die Werkstückhalterung 4 besteht aus einer runden Grundbodenplatte und einer zylindrisch darüber und nach oben offenen Wandung 6 und dient auf ihrer Bodenplatte über (nicht dargestellte) Einspannmittel zur Lagerung eines zu polierenden Werkstücks 7. Die Bodenplatte und die Wandungen 6 bilden ein Gefäß, das durch einen Deckel 8 von oben her verschließbar ist. Der Deckel 8 wird über Schraubverbindungen und Abstandsstükke am Tisch 1 befestigt und ist auf den Zylinderrand der Wandung 6 mit einem Ansatz 9, der das Gefäß abdichtet, aufgesetzt.In the illustration, 1 denotes a table top that is in a guide 2 receives a workpiece holder 4 rotatably mounted about an axis 3. The workpiece holder 4 consists of a round base plate and a cylindrical one above and gradually wall 6 open at the top and serves on its base plate (not shown) Clamping means for supporting a workpiece to be polished 7. The base plate and the walls 6 form a vessel which can be closed by a cover 8 from above is. The cover 8 is fastened to the table 1 by means of screw connections and spacers and is on the cylinder edge of the wall 6 with a projection 9, which seals the vessel, put on.

Der Deckel 8 trägt eine Trennwand lo, die in das Gefäß 4,6 hineinragt und den Gefäßinnenraum in zwei Teilkammern 11 und 12 aufteilt. Die Trennwand lo ragt bis in die Nähe der Oberfläche des Werkstücks 7 und trägt an ihrem unteren Ende einen Ansatz 13, der im wesentlichen parallel zur Oberfläche des Werkstücks 7 verläuft.The cover 8 carries a partition lo which protrudes into the vessel 4, 6 and divides the interior of the vessel into two sub-chambers 11 and 12. The partition lo extends up to the vicinity of the surface of the workpiece 7 and carries on its lower End of a projection 13 which is substantially parallel to the surface of the workpiece 7 runs.

Beiderseits der Trennwand lo sind Preßstempel 14 und 15 angeordnet, die mittels Hubkolbenmotoren 16 und 17 im Gegentakt in den Teilkammern 11 und 12 verstellt werden können. Die Eubkolbenmotoren 16 und 17 sind ebenso wie die Preßstempel 14 und 15 am Deckel 8 gelagert und mittels einer Abdichtung durch den Deckel 8 hindurchgeführt.On both sides of the partition lo press rams 14 and 15 are arranged, by means of reciprocating piston motors 16 and 17 in push-pull in the sub-chambers 11 and 12 can be adjusted. The Eubkolbenmotoren 16 and 17 are just like the rams 14 and 15 mounted on the cover 8 and passed through the cover 8 by means of a seal.

Die Drehachse 3 ist mittels eines Getriebes durch einen Antriebsmotor 20 mit vorgebbarer Drehzahl drehbar.The axis of rotation 3 is driven by a drive motor by means of a gear 20 rotatable at a predefinable speed.

Die beschriebene Vorrichtung arbeitet wie folgt: Durch Lösen der Schraubverbindungen wird der Deckel 8 von der dargestellten Vorrichtung abgehoben und das Werkstück 7 in der zugehörigen Kammer der Werkstückhalterung 4 eingespannt. Danach wird der Deckel 8 aufgesetzt und mit dem Tisch 1 verschraubt.The device described works as follows: By loosening the screw connections the cover 8 is lifted from the device shown and the workpiece 7 clamped in the associated chamber of the workpiece holder 4. After that, the Cover 8 put on and screwed to table 1.

Dabei wird die durch die Werkstückhalterung 4 gebildete Kammer mittels des Deckelansatzes 9 abgedichtet und der gebildete Kammerinnenraum über (nicht dargestellte) Zuleitungsöffnungen mit einer geeigneten plastisch verformbaren Poliermasse gefüllt und mittels der Preßstempel 14 und 15 im Gegentakt durch die Kammern 11 und 12 gepreßt. Dabei wird die Poliermasse unterhalb des Ansatzes 13 entlang der Oberfläche des Werkstücks 7 zwischen den beiden Teilkammern 11 und 12 hin- und herbewegt und die Oberfläche des Werkstücks 7 entsprechend poliert.The chamber formed by the workpiece holder 4 is by means of of the lid attachment 9 sealed and the chamber interior formed over (not shown) Feed openings filled with a suitable plastically deformable polishing compound and pressed through the chambers 11 and 12 by means of the rams 14 and 15 in push-pull. The polishing compound is below the approach 13 along the surface of the Workpiece 7 moved back and forth between the two sub-chambers 11 and 12 and the The surface of the workpiece 7 is polished accordingly.

Nach Beendigung des Poliervorganges wird der Deckel 8 abgehoben und das Werkstück 7 gegebenenfalls durch ein neu zu polierendes Werkstück ersetzt.After finishing the polishing process, the cover 8 is lifted off and the workpiece 7 is optionally replaced by a workpiece to be re-polished.
