Description

Wie man in der Zeichentechnik Kurven ohne Verwendung eines Zirkels nach dem geometrischen Lehrsatz zeichnen kann, daß alle Peripherie winkel über der gleichen Sehne einander gleich sind und sich hiemach Kurven zeichinen lassen, indem ein Winkel längs zweier Widerlagerpunkte bewegt wird, so daß ' seine Spitze einen Kreisbogen beschreibt, besteht auch insbesondere in der Optik das Verlangen, gekrümmte Flächen unter Vermeidung des Kopierverfahrens herzustellen, weil auf diese Weise die Herstellung nicht nur wirtschaftlicher, sondern auch zwangsläufig geometrisch genauer durchführbar ist und die bisher auftretenden großen Schwierigkeiten und der Aufwand an teueren Einrichtungen und Arbeitsverfahren in Fortfall kommen.How to draw curves without using a compass after the Geometric theorem can draw that all the periphery angles over the same chord are equal to each other, and curves can then be drawn by making an angle along two abutment points is moved so that 'its tip describes an arc of a circle also, especially in optics, the desire to avoid curved surfaces of the copying process, because in this way the production is not only more economical, but also inevitable is geometrically more precisely feasible and the great difficulties that have arisen up to now and the expense of expensive equipment and work processes is no longer necessary.

Zu diesem Zweck wird mit der Erfindung vorgeschlagen, die Berührungsstelle zwischen Werkzeug und Werkstück in der Mittelachse eines winkeleinstellbaren, entlang eines Ringes im Bereich der herzustellenden Fläche bewegbaren Dreifußes anzuordnen. Da der Dreifuß winkeleinstellbar ist, lassen sich mit der gleichen Vorrichtung durch eine entsprechende Einstellung des von den Schenkeln des Dreifußes gebildeten Winkels verschiedene geometrisch ähnliche Kurveinflächen herstellen. Die erzeugte Kurve ist jeweils im Querschnitt eine Ellipse.For this purpose it is proposed with the invention, the point of contact between Tool and workpiece in the central axis of an adjustable angle, along a ring to be arranged in the area of the surface to be produced movable tripod. There the tripod The angle can be adjusted with the same device by a corresponding Adjustment of the angle formed by the legs of the tripod different Create geometrically similar curved surfaces. The curve generated is in each case in cross section an ellipse.

Die Vorrichtung nach der Erfindung ist auf der Zeichnung in einem Ausführungsbeispiel veranschaulicht. Es zeigen:
Fig. ι eine Draufsicht,The device according to the invention is illustrated in the drawing in one embodiment. Show it:
Fig. Ι a plan view,

Fig. 2 einen Querschnitt.Fig. 2 is a cross section.

Ein an der Spitze mit einem Werkzeug 3 versehener Dreifuß ist im Bereich der von dem Werkzeug herzustellenden Fläche entlang eines Auflageriinges 2 beliebig einstellbar. Der Dreifuß besteht aus drei untereinander in der Draufsicht einem Winkel von je 1200 einschließenden Schenkeln 1, die schirmartig zu einem gemeinsamen Scheitelpunkt zusammengeführt sind, der zugleich der Berührungspunkt zwischen Werkzeug und Werkstück ist. Der Winkel dieser Schenkel zu einer in deren Mittelachse zu errichtenden Senkrechten ist entsprechend der herzustellenden Kurvenfläche einstellbar. Das an der Scheitelspitze des Dreifußes angebrachte Arbeitswerkzeug go kann im Austausch hierzu durch das Werkstück ersetzt werden.A tripod provided with a tool 3 at the tip can be adjusted as desired along a support ring 2 in the area of the surface to be produced by the tool. The tripod consists of three with each other in plan view, an angle of 120 0 enclosing legs 1, which are brought together like an umbrella to form a common vertex which is also the point of contact between tool and workpiece. The angle of these legs to a perpendicular to be established in their central axis can be adjusted according to the curved surface to be produced. The work tool go attached to the apex of the tripod can be replaced by the workpiece in exchange for this.
