Description

Die Spanneinrichtungen an Mehrspindelautomaten zum Festhalten von Stangenmaterial sind in der Weise durchgebildet, daß ein Spannkonus auf mehrere, wenigstens zwei Winkelhebel einwirkt, die sich mit ihren kurzen Schenkeln gegen ein Spannrohr innerhalb der Arbeitsspindel legen und den vom Konus ausgeübten Druck dadurch auf die Spannpatrone übertragen. Es hat sich nun herausgestellt, daß diese Winkelhebel öfter brechen, weil sie den an sie gestellten Anforderungen nicht genügen. Andererseits konnte man die Abmessungen der Spannhebel nicht verstärken, weil die Entfernungen der Spindeln, welche das Material führen, besonders bei Vierspindelautomaten, festliegen und nicht größer gewählt werden können.The clamping devices on multi-spindle machines for holding bar material are designed in such a way that a clamping cone on several, at least two Angle lever acts, which with its short legs against a clamping tube within the work spindle and thereby the pressure exerted by the cone on the clamping cartridge transfer. It has now been found that these angle levers break more often, because they do not meet the requirements placed on them. On the other hand, you could Do not increase the dimensions of the clamping lever because the distances between the spindles, which guide the material, especially with four-spindle machines, are fixed and not can be chosen larger.

Durch die vorliegende Erfindung wird nun eine Verstärkung der Abmessungen derThe present invention is now an increase in the dimensions of the

as sind. Da die Spindeln der Vierspindelautomaten zwangläufig durch Zahnräder angetrieben werden, so kann man die Aussparungen so einrichten, daß bei der Drehung die Spannhebel der einen Spindel in die Aussparungen der benachbarten Spindeln eintreten. Eine Ausführungsform dieser Einrichtung ist auf der Zeichnung dargestellt.as are. As the spindles of the four-spindle machines are inevitably driven by gears, so you can set up the recesses so that the clamping lever when rotating of one spindle enter the recesses of the adjacent spindles. One embodiment of this device is on shown in the drawing.

Abb. ι zeigt den Spindelkopf eines Revolverautomaten in Seitenansicht, J Abb. 2 in Vorderansicht. Die Spindeln α werden durch die Zahnräder b in zwangläufige Umdrehung versetzt. Auf den Spindeln sitzen die Körper c, welche die drehbar angeordneten, winkelförmig ausgebildeten Hebel d tragen, die sich gegen den Konus g legen. Die Körper c sind mit Aussparungen h versehen, in welche die Hebel d bei ihrer Drehung eintreten. Die Hebel d und die Körper c können an den Teilen, an denen die Hebel gelagert sind, so stark ausgeführt werden, wie es die Achsenentfernung der Spindeln zuläßt. Die Aussparungen h sind dementsprechend zu bemessen.Fig. Ι shows the spindle head of a turret machine in side view, J Fig. 2 in front view. The spindles α are forced to rotate by the gears b. On the spindles sit the bodies c, which carry the rotatably arranged, angled levers d , which lie against the cone g. The bodies c are provided with recesses h into which the levers d enter as they rotate. The levers d and the body c can be made as strong on the parts on which the levers are mounted as the distance between the axes of the spindles allows. The recesses h are to be dimensioned accordingly.
