Description
Die Erfindung bezieht sich auf ein Spannbackenfutter zum Festhalten des Kopfs von Werkstücken, die mit Gewinde zu versehen sind. Das Neue der Erfindung besteht darin, daß die unter Federwirkung stehenden Backen des Spannbackenfutters mittels einer durch eine Kurvenbahn bewegten Schiebervorrichtung geschlossen werden, worauf ein federnder, sich nicht drehender Festhalter gegen die Stirnfläche des Werkstückkopfs gepreßt wird, welcher beim Drehen des Werkstücks in die Kopfnut desselben einschnappt. Nach dem Einschnappen des federnden Festhalters wird ein ihn tragender Teil mittels eines von einer Feder beeinflußten und durch eine Kurvenbahn gesteuerten Kniehebelgelenks gegen den Werkstückkopf gedrückt, so daß das Werkstück während des Gewindeschneidens in seiner Arbeitslage sicher fest-The invention relates to a jaw chuck for holding the head of Workpieces that are to be provided with threads. The novelty of the invention is that that the under spring action jaws of the clamping jaw chuck by means of a be closed by a cam moving slide device, whereupon a resilient, non-rotating retainer pressed against the face of the workpiece head which snaps into the head groove of the workpiece when it is turned. After the resilient retainer has snapped in, a part carrying it is by means of a toggle joint influenced by a spring and controlled by a cam track pressed against the workpiece head, so that the workpiece during tapping securely in his working position

Eine Ausführungsform eines Spannbackenfutters entsprechend der Erfindung ist beispielsweise in der Zeichnung dargestellt. Abb. ι zeigt die Vorrichtung zum Festhalten des Kopfs von Werkstücken, die mit Gewinde zu versehen sind, in Stirnansicht und teilweise im Schnitt, währendOne embodiment of a jaw chuck according to the invention is for example shown in the drawing. Fig. Ι shows the device for holding of the head of workpieces to be threaded, in front view and partially in section, while
Abb. 2 dieselbe Vorrichtung in Seitenansicht und teilweise im Längsschnitt zeigt. · Die Werkstücke 1, die von der Rinne 1' in die Nutentrommel 2 gelangen, werden von deren Nuten 3 erfaßt und mittels eines Armes 4 je an ein Spannbackenfutter 5 mit Backen 6 übergeführt. Die Backen 6 des Spannbackenfutter werden durch eine zweiteilige Schiebervorrichtung 7 und 8, die von einer Kurvenbahn 9 und einer in dieser angeordneten Rolle betätigt wird, um das Werkstück geschlossen. Hierauf wird der stillstehende Festhalter 11 mit einem verhältnismäßig leichten, von einer Feder 12 hervorgerufenen Druck gegen den Kopf des Werkstücks gepreßt, so daß der Festhalter 11 nach einer Verdrehung des Werkstücks leicht in die Nut des Werkstückkopfs einschnappen kann.Fig. 2 shows the same device in side view and partly in longitudinal section. · The workpieces 1, which get from the channel 1 'into the grooved drum 2, are of whose grooves 3 are detected and by means of an arm 4 each to a clamping jaw chuck 5 with Jaws 6 transferred. The jaws 6 of the jaw chuck are by a two-part slide device 7 and 8, which is arranged by a cam track 9 and one in this Roller is actuated to close the workpiece. Then the still one becomes Retainer 11 with a relatively light, caused by a spring 12 Pressure pressed against the head of the workpiece, so that the holder 11 after a Twisting of the workpiece can easily snap into the groove of the workpiece head.
Sogleich, nachdem der Festhalter in die Nut des Kopfs eingeschnappt ist, wird ein die Feder 12 umgebender, den Festhalter tragender hülsenförmiger Teil mittels eines von der Feder 19 beeinflußten und durch eine Kurvenbahn 21 gesteuerten Kniehebelgelenks 18 gegen den Werkstückkopf mit großer Kraft angedrückt, so daß der Werkstückkopf während des Gewindeschneidens in der Arbeitslage sicher festgehalten wird. Nach dem Ge- windeschneiden wird das Kniehebelgelenk 18 unter Überwindung der Kraft der Feder 19 nach oben eingeknickt, was durch die Gabel bewirkt wird, die eine von der Kurvenscheibe 21 gesteuerte Rolle 22 trägt, worauf das Werkstück entfernt werden kann.Immediately after the retainer is snapped into the groove of the head, a die The sleeve-shaped part surrounding the spring 12 and carrying the retainer by means of one of the Spring 19 influenced and controlled by a cam track 21 toggle joint 18 against the workpiece head is pressed with great force so that the workpiece head is securely held in the working position during thread cutting. After the The toggle joint 18 will cut by overcoming the force of the spring 19 buckled upwards, which is caused by the fork, which is one of the cam 21 controlled roller 22 carries, whereupon the workpiece can be removed.
