Description

Vorrichtung zum Fertigbearbeiten der Innenflächen des Gabelausschnittes von Uhrwerkankern Gegenstand vorliegender Erfindung ist eine Vorrichtung zum Fertigbearbeiten der Innenflachen des Gabelausschnittes von Uhrwerkankern und besteht darin, daß eine Topffräse von außen nach innen den Seiten des Ausschnittes entlang geführt -wird, um eine Oberfläche von konvexem Querschnitt herzustellen und die Lage dieser Ausschnittseiten der Ankerachse gegenüber genau festzulegen.Device for finishing the inner surfaces of the fork cutout of clockwork armatures The subject of the present invention is a device for finishing the inner surfaces of the fork cutout of clockwork anchors and consists in that a pot cutter from the outside to the inside along the sides of the cutout -is used to produce a surface of convex cross-section and the location of this Specify cut-out sides of the anchor axis exactly opposite.

Beiliegende Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes, wobei Fig: i einen Grundriß der allgemeinen Anordnung der Vorrichtung, Fig. 2 einen Längsschnitt und Fig.3 einen Querschnitt des verwendeten Fräswerkzeuges darstellt.The accompanying drawing shows an embodiment of the subject matter of the invention, wherein Fig. 1 is a plan view of the general arrangement of the device, Fig. 2 is a plan view Longitudinal section and FIG. 3 shows a cross section of the milling tool used.

Der Werkzeughalter öder Spindel zur Bearbeitung der Innenflächen des Gabelausschnittes besitzt eine horizontale Drehachse i, mit welcher auch die Symmetrieachse ,2 der z. B. in einem Drehsupport 3 von Zangen festgehaltenen Ankers 5 in Linie gebracht wird. Das Werkzeug, eine Topffräse 6, also ein an seinem rechtwinklig zur Achse abgeschnittenen Rand mit Zähnen versehenes hohlzylindrisches Werkzeug, sitzt am Ende einer in zwei Lagern 7 und 8 drehbar und axial verschiebbar gelagerten Spindel 9 mit einer Schnurscheibe io und einem mit Anschlagflachen i i versehenen Handgriff 12. Eine Druckfeder 13 hält den Werkzeughalter in vom Drehsupport zurückgezogener Stellung fest, wobei die Schnurscheibennabe am Lager 8 anliegt. Die Spindelg muß den nach außen konvergierenden Seitenflächen der Gabelarme entsprechend der Symmetrieachse des Ankers gegenüber zwei seitliche Schieflagen einnehmen. Zu diesem Zweck ist die Lagerplatte 14 dieses Werkzeughalters um den Mittelpunkt des dem Anker zunächst liegenden Lagers 7 schwingbar auf ihrer Grundplatte 1 5 gelagert, und zwar innerhalb der Grenzen, welche durch zwei ortsfeste Anschläge 16 den Anschlagflächen i i gegenüber bestimmt sind. Um das Werkzeug in eine genau begrenzte Arbeitsstellung zu bringen, muß die Spindel 9 mittels des Handgriffes 12 bis zum Anstoßen der Schnurscheibennabe am vorderen Lager 7 vorgestoßen werden, während .eine der Anschlagflächen i i mit einem Anschlag 16 in Berührung gehalten wird.The tool holder or spindle for machining the inner surfaces of the The fork cutout has a horizontal axis of rotation i, with which also the axis of symmetry , 2 of the z. B. held in a rotary support 3 by pliers armature 5 in line is brought. The tool, a pot cutter 6, so one at its right angles to Axis cut edge with teeth provided hollow cylindrical tool, sits at the end of a spindle mounted rotatably and axially displaceably in two bearings 7 and 8 9 with a cord disc io and a handle provided with stop surfaces i i 12. A compression spring 13 holds the tool holder in the retracted position from the rotary support Fixed position, with the pulley hub resting against the bearing 8. The spindle must the outwardly converging side surfaces of the fork arms corresponding to the axis of symmetry take up two lateral inclinations opposite the anchor. To this end, the Bearing plate 14 of this tool holder around the center of the anchor initially lying bearing 7 swingably mounted on its base plate 1 5, namely within the limits, which by two stationary stops 16, the stop surfaces i i opposite are determined. To bring the tool into a precisely defined working position, the spindle 9 must be by means of the handle 12 until it hits the pulley hub be pushed forward at the front bearing 7, while .one of the stop surfaces i i with a stop 16 is held in contact.

Die Vorrichtung zum Festhalten des Ankers, in vorliegendem Beispiel die Zange q., ist so eingerichtet, daß die Symmetrieachsen der nacheinander eingeführten, zur Bearbeitung bestimmten Anker stets dieselbe Lage einnehmen müssen.The device for holding the anchor, in this example the clamp q., is set up so that the axes of symmetry of the successively introduced, anchors intended for machining must always be in the same position.

Die Anschläge 16 können mittels Mikrometerschrauben 17 genau eingestellt werden.The stops 16 can be precisely adjusted by means of micrometer screws 17 will.
