KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf Vorrichtungen mit einstellbarem Fräserarm zum Einfräsen von Schraubennuten in Hohlkörper. Die Erfindung besteht darin, daß der Vorschubspindel bei ihrem Vorschub durch eine in verschiedenen Lagen einstellbare Kette eine Drehung erteilt wird, /The invention relates to devices with an adjustable milling arm for milling of screw grooves in hollow bodies. The invention consists in that the feed screw a rotation as it is advanced by a chain that can be set in different positions is granted /
Die Zeichnung stellt die Vorrichtung in Fig. ι bis 4 in Schnittzeichnungen dar. Fig. 5 ist ein vergrößerter Querschnitt durch den Fräserarm.The drawing shows the device in FIGS. 1 to 4 in sectional drawings Figure 3 is an enlarged cross-section through the cutter arm.
Auf einem horizontalen oder vertikalen Rahmen α ist der feststellbare Tisch b und ein Lager mit dem Lagerkopf c angeordnet. In diesem führt sich die Spindel e, auf deren Umfläche eine biegsame Gelenkkette f ruht, welcher durch die dreh- und feststellbare Büchse g eine in Schraubenlinienform verlaufende Lage auf der Spindel gegeben werden kann. Die Büchse g wird durch eine' Mutter h gegenüber der Spindel β festgestellt. Die Kette führt sich in einer bogenförmig ausgearbeiteten Nut t. ■ ' ' . .The lockable table b and a bearing with the bearing head c are arranged on a horizontal or vertical frame α. In this, the spindle e, a flexible link chain rests f on whose circumferential surface leads formed by the rotatable and lockable sleeve g extending in the helical shape can be given location on the spindle. The sleeve g is determined by a 'nut h opposite the spindle β . The chain runs in an arcuate groove t. ■ ''. .
Der Vor-' bzw. Rückwärtsgang der Spindel erfolgt durch eine lose unter der Spindel angeordnete und mittels Ringes k gehaltene Zahnstange I, die durch Handrad m und Zahnrad η bewegt wird.The forward or reverse gear of the spindle is carried out by a rack I loosely arranged under the spindle and held by means of a ring k , which is moved by the handwheel m and the toothed wheel η .
Der Fräserarm 0 ist im Gelenk p beweglich und wird durch die Einstellvorrichtung q in beliebig schräger Lage, dem Durchmesser des Hohlkörpers entsprechend, festgehalten.The milling arm 0 is movable in the joint p and is held by the setting device q in any inclined position, corresponding to the diameter of the hollow body.
Im Innern des zweiteiligen Fräserarmes sind Zahnräder r auf Kugeln gelagert, die mit der Antriebscheibe s und konischen Rädern t in Verbindung stehend zum Antrieb des Fräsers u dienen. Die Räderschutzhülse ν hält die beiden Hälften des Fräserarmes zusammen, dessen Antriebvorrichtung für den Fräser auch aus einer inneren Längswelle und konisehen Rädern bestehen kann.In the interior of the two-part cutter arm, gears r are mounted on balls which, in connection with the drive pulley s and conical wheels t, serve to drive the cutter u. The wheel protection sleeve ν holds the two halves of the cutter arm together, whose drive device for the cutter can also consist of an inner longitudinal shaft and conical wheels.
Durch die drehbar vorrückende Spindel e bei schräg gestelltem Fräserarm können alle gewünschten schraubenförmigen Nuten in Hohlkörper gefräst werden.With the rotatably advancing spindle e with the cutter arm inclined, all desired helical grooves can be milled in hollow bodies.
