Description

Vorrichtung zum Schleifen von Kugelflächen, insonderheit an optische Linsen. Die Erfindung betrifft eine Vorrichtung zum Schleifen von Kugelflächen, insonderheit an optische Linsen derjenigen bekannten Gattung, bei der das Werkstück in der der zu erzielenden Form entsprechenden Bahn zwangläufig geführt und dabei zur Hervorbringung des notwendigen Arbeitsvorschubes gedreht wird, und besteht darin, daß die in Richtung des Schwingarmes für die Werkstückhalter liegende u#mlatifende Werkstückachse mit beiderseits freiliegenden Enden in einer von dem Schwingarm .an einem aufrechten Arm erhöht getragenen Hülse gelagert ist, so daß sie an ihren beiden Enden Werkstücke aufnehmen und diese an je einer im Bereich ihrer Sch @wingungshahn angeordneten Schleifscheibe, einerseits konkav, anderseits konvex, aber mit ungleichen Kugelflächenkrümmungsradien geschliffen «erden können.Device for grinding spherical surfaces, especially optical ones Lenses. The invention relates to a device for grinding spherical surfaces, in particular to optical lenses of the known type in which the workpiece inevitably guided in the path corresponding to the shape to be achieved and thereby is rotated to produce the necessary work feed rate, and consists of that the u # mlatifende lying in the direction of the swing arm for the workpiece holder Workpiece axis with exposed ends on both sides in one of the swing arm .an an upright arm is supported raised sleeve so that it is attached to both of them Pick up workpieces at the ends and attach them to one each in the area of their vibration cock arranged grinding wheel, on the one hand concave, on the other hand convex, but with unequal Spherical surface radii of curvature ground «.

Die Vorrichtung ist in der Zeichnung dargestellt, und zwar zeigen Abb. r einen Aufriß, teilweise im Schnitt, Abb. 2 einen Gru ndriß.The device is shown in the drawing, namely show Fig. R an elevation, partly in section, Fig. 2 a plan.

r und i' sind die Werkzeuge, 2 tind 2' die Werkstücke, die von den beiderseits freiliegenden Enden der Werkstückachse 3 getragen werden. Die Werkstückachse wird von der Riemenscheibe 7 angetrieben und ist in einer Hülse 9 gelagert, welche von den Schwingarm 13 an einem aufrechten Arm 14 mittels der Hülse 15 erhöht getragen wird. Der Schwingarm 13 schwingt um den Zapfen 4, der im Schlitz 5 mit dem Befestigungshölzen 6 verstellt werden kann. Die Hülse 9 ist mittels des Zapfens zo querverschiebbar auf dem Ouersupport gelagert, der auf dem Bett durch das Rad 1z und Spindel rr verschoben wird.r and i 'are the tools, 2 and 2' are the workpieces which are carried by the ends of the workpiece axis 3 that are exposed on both sides. The workpiece axis is driven by the pulley 7 and is mounted in a sleeve 9, which is supported by the swing arm 13 increases to an upright arm 14 by means of the sleeve 1. 5 The swing arm 13 swings around the pin 4, which can be adjusted in the slot 5 with the fastening wood 6. The sleeve 9 is mounted transversely by means of the pin zo on the Ouersupport, which is moved on the bed by the wheel 1z and spindle rr.
