Description

Die üblichen Maschinen zum Schleifen und Polieren ebener und gewölbter Flächen sind im allgemeinen zur gleichzeitigen Bearbeitung einer größtmöglichen Anzahl von Flächen eingerichtet, und es ist unwirtschaftlich, sie für die Bearbeitung von Einzelstücken oder nur weniger Stücke einzusetzen. Die den Gegenstand der Erfindung bildende und hierunter näher beschriebene sowie in den Zeichnungen dargestellte neue Einrichtung zum SchleifenThe usual machines for grinding and polishing flat and curved surfaces are generally set up for simultaneous processing of the largest possible number of surfaces, and it it is uneconomical to use them for processing individual pieces or just a few pieces. The forming the subject matter of the invention and described in more detail below as well as in the drawings illustrated new device for grinding

ίο und Polieren ebener oder gewölbter Flächen zeichnet sich durch große Einfachheit, geringen Platzbedarf und leichte Bedienbarkeit aus, unter gleichzeitiger Lieferung besserer Arbeitsergebnisse, die im wesentlichen darauf beruhen, daß die gesamte Kraft- und Bewegungsübertragung durch Riemen oder Zahnräder erfolgt. Die neue Einrichtung eignet sich besonders für die Oberflächenbehandlung von Einzelstücken oder nur weniger Werkstücke. Sie ist in der Anwendung nicht nur auf die Bearbeitung von optischen Linsen beschränkt, sondern eignet sich auch für die Herstellung dünner Mineralschliffe tür mikroskopische Untersuchungen.ίο and polishing flat or curved surfaces draws are characterized by great simplicity, small footprint and ease of use, while at the same time Delivery of better work results, which are based essentially on the fact that the entire force and Movement is transmitted by belts or gears. The new facility is particularly suitable for the surface treatment of individual pieces or just a few work pieces. she is in the application is not limited to the processing of optical lenses, but is suitable also for the production of thin mineral sections for microscopic examinations.

Eine Ausführungsform der neuen Einrichtung ist in den schematisch gehaltenen Zeichnungen inAn embodiment of the new device is shown schematically in the drawings in FIG

as Fig. ι in einer Ansicht und inas Fig. ι in a view and in

Fig. 2 in einer Draufsicht dargestellt.
Die Welle des Antriebsmotors 1 trägt an dem einen Ende zwei Schnurscheiben 2, die durch Riemen 3 mit den Arbeitsköpfen 4 gekuppelt sind, auf die die zu bearbeitenden Stücke 5 aufgekittet sind. Das andere Ende der Motorwelle trägt ebenfalls eine Scheibe, die über ein Reduziergetriebe 6 die Werkzeuge 7 antreibt. Hierzu ist eine Antriebsscheibe 8 des Reduziergetriebes 6 mit einem Exzenterzapfen 9 gekuppelt, der einstellbar ist und durch eine Kurbelstange 10 einen waagerechten Schenkel 11 eines Gelenkparallelogramms in Bewegung setzt, dessen Gegenarm 12 fest angeordnet ist. An dem beweglichen Arm 11 des Parallelogramms sind die Halter 13 für die Werkzeuge 7 befestigt, von denen jedoch nur einer dargestellt ist. Jeder Halter ist durch eine einstellbare, nicht eingezeichnete Feder belastet, die ihn nach unten zieht und den erforderlichen Arbeitsdruck zwischen Werkzeug und Werkstück sichert. Zur Einstellung verschiedener Geschwindigkeiten des Werkstückes oder der Werkzeuge kann jede der Antriebsscheiben aus einem Satz von Scheiben verschiedener Durchmesser ausgetauscht werden. Auch können die in dem Ausführungsbeispiel eine feste Länge aufweisenden Teile für den Antrieb der Werkzeuge durch in der Länge einstellbare Glieder ersetzt werden, um die Einstellung der Werkzeuge zu den Werkstücken ändern zu können.Fig. 2 shown in a plan view.
The shaft of the drive motor 1 carries at one end two cord pulleys 2 which are coupled by belts 3 to the working heads 4, onto which the pieces 5 to be processed are cemented. The other end of the motor shaft also carries a disk which drives the tools 7 via a reduction gear 6. For this purpose, a drive pulley 8 of the reduction gear 6 is coupled to an eccentric pin 9, which is adjustable and, by means of a connecting rod 10, sets a horizontal leg 11 of a joint parallelogram in motion, the counter arm 12 of which is fixedly arranged. The holders 13 for the tools 7 are attached to the movable arm 11 of the parallelogram, but only one of them is shown. Each holder is loaded by an adjustable spring, not shown, which pulls it down and ensures the required working pressure between the tool and the workpiece. To set different speeds of the workpiece or the tools, each of the drive disks can be exchanged from a set of disks of different diameters. The parts for driving the tools, which in the exemplary embodiment have a fixed length, can also be replaced by members adjustable in length in order to be able to change the setting of the tools in relation to the workpieces.
