    Werkstückzuführvorrichtung   für Bearbeitungsmaschinen, insbesondere   Spiralbohrerfräsmaschinen.   



   Den Gegenstand der Erfindung bildet eine Werkstückzuführvorrichtung für Be-   arbeitungsmaschinen, insbesonders, Fräsmaschinen zur Erzeugung von Spiralbohrern. Das Wesen der Erfindung besteht darin, dass die im Spindelstock gelagerte Hohlspindel unter   der Ausfallöffnung des   Sammelbehälters   für die Werkstücke einen Längsschlitz aufweist, durch welchen das von der Sperrvorrichtung des Sammelbehälters freigegebene Werkstück in   die Hohlspindel fällte   in welcher es durch einen sich längsbewegenden Dorn gegen das als Spannfutter ausgebildete vordere Spindelende befördert und daselbst in der richtigen Lage für die Bearbeitung festgehalten wird. 



   In der Zeichnung ist die Erfindung an einer Spiralbohrerfräsmaschine beispielsweise veranschaulicht, und zwar zeigt Fig, i eine Seitenansicht und Fig, 2 einen Schnitt nach der Linie   c-d.   



   Der Sammelbehälter   A   für die Werkstücke   4   ist an dem längsbeweglichen Spindelstock 19 befestigt, in dessen Lagern 20 die hohle Arbeitsspindel D drehbar gelagert ist. 



  Die Spindel D weist unter der Ausfallöffnung des Sammelbehälters   A   bzw. des Gleitkanals C einen Längsschlitz 6'auf, durch welchen das von der Sperrvorrichtung B des Behälters   A   bei jedem Arbeitsgang der Maschine freigegebene Werkstück in die Längsbohrung der Spindel D fällt. In die Bohrung 6 greift ein Dorn 7 ein, der mit Hilfe eines zweiarmigen Hebels 8 von einer Kurvenscheibe 9 hin und her bewegt wird und bei seiner Einwärtsbewegung das durch   den. Längsschlitz   6'in die Bohrung 6 gefallene Werkstück , gegen das als Spannfutter ausgebildete Spindelende befördert, woselbst es in der richtigen Lage für die Bearbeitung festgehalten wird.

    Workpiece feeding device for machine tools, in particular twist drill milling machines.



   The subject matter of the invention is a workpiece feed device for processing machines, in particular milling machines for producing twist drills. The essence of the invention is that the hollow spindle mounted in the headstock has a longitudinal slot under the discharge opening of the collecting container for the workpieces, through which the workpiece released by the locking device of the collecting container fell into the hollow spindle in which it fell through a longitudinally moving mandrel against the as Chuck trained front spindle end conveyed and is held there in the correct position for processing.



   In the drawing, the invention is illustrated by way of example on a twist drill milling machine, namely FIG. 1 shows a side view and FIG. 2 shows a section along the line c-d.



   The collecting container A for the workpieces 4 is attached to the longitudinally movable headstock 19, in whose bearings 20 the hollow work spindle D is rotatably mounted.



  The spindle D has a longitudinal slot 6 'under the discharge opening of the collecting container A or the sliding channel C, through which the workpiece released by the locking device B of the container A during each operation of the machine falls into the longitudinal bore of the spindle D. In the bore 6 engages a mandrel 7, which is moved back and forth by a cam 9 with the help of a two-armed lever 8 and when it moves inward through the. Workpiece that has fallen into the bore 6 in the longitudinal slot 6 'is conveyed against the spindle end, designed as a chuck, where it is itself held in the correct position for processing.
