 bewegung etwas zurückgehalten wird und die Mutters dabei einen Augenblick an ihrer Drehung hindert, welche auf diese Weise die Spindel a vorschiebt. Bei Abgleiten der Nase h wird der Sperrhebel e über einen oder mehrere Zähne auf der Verzahnung d gleitend vorgeschnellt und der Hebelarm   g   gelangt wieder in seine Normalstellung. 



   Derselbe Vorgang wiederholt sich nun während der Arbeitsleistung bei jeder vollen Um- drehung der Spindel. 



   Bei der Rückschaltung der Spindel nach Beendigung der Arbeit stösst die Nase h mit ihrer   Rückennäche gegen   den Anschlag r und wird in dieser Stellung festgehalten, wobei gleichzeitig die Sperrklinke q in die   Verzahnung   d eingreift und die Mutter b gegen Drehung zwangsläufig sperrt, so dass sich die Spindel a in rascher Gangart zurückschiebt. Bei maschinellem Antrieb der Spindel kann dafür gesorgt werden, dass die Spindel bei Erreichung der   rückwärtigen   Endlage den Antrieb der Spindel selbsttätig ausschaltet. 



   Anstatt dieses soeben beschriebenen Vorganges lässt sich nun auch die gleiche Wirkung erzielen, wenn man statt der rotierenden Scheibe k einen feststehenden Körper wählt und den Hebel g statt den starren Anschlag r durch einen beweglichen Anschlag in Tätigkeit setzt.

 EMI2.1
 Movement is held back and the mother prevents it from rotating for a moment, which advances the spindle a in this way. When the nose h slides off, the locking lever e is slid forward by one or more teeth on the toothing d and the lever arm g returns to its normal position.



   The same process is now repeated during the work with each full revolution of the spindle.



   When the spindle is switched back after the work is finished, the nose h hits the stop r with its back surface and is held in this position, while at the same time the pawl q engages the toothing d and the nut b inevitably locks against rotation so that the Moves spindle a back at a rapid pace. If the spindle is mechanically driven, it can be ensured that the spindle automatically switches off the spindle drive when it reaches the rear end position.



   Instead of this process just described, the same effect can now also be achieved if a stationary body is selected instead of the rotating disk k and the lever g is activated by a movable stop instead of the rigid stop r.

 

Claims (1)

PATENTANSPRUCH : Vorschubvorrichtung für Spindeln an Arbeitsmaschinen aller Art, bei welcher ein periodischer Vorschub und ein schneller Rücklauf durch zeitweise Sperrung einer Mutter erfolgt., dadurch gekennzeichnet, dass die Spindel bei Leergang und Arbeitsbeanspruchung zwangläufig verschieden gelinelleit Vorsehub erhält, wobei die Umschaltung der Spindel vom schnellen zum langsamen Vorschub und umgekehrt selbsttätig durch den auftretenden Arbeitswiderstand erfolgt. PATENT CLAIM: Feed device for spindles on work machines of all kinds, in which a periodic feed and a fast return takes place by temporarily blocking a nut., Characterized in that the spindle inevitably receives different linear feeds during idle operation and workload, whereby the spindle is switched from fast to slow Feed and vice versa takes place automatically by the occurring work resistance.
