  Vorschubeinrichtung in einer Hämmermaschine 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 
 EMI2.1 
    dgl.Abführungen --16-- für   das Arbeitsmittel auf. 



   Es liegt im Sinne der Erfindung, dass der Arbeitszylinder sein Hohlkolben--13, 14-sowie die in diesem Hohlkolben drehbar gelagerte   Hohlwelle--7--und   auch die Hämmerwerkzeuge --3-- auf einer gemeinsamen Achse angeordnet sind. 



   Die   Hohlwelle --7-- sowie   das Rohr--13--des Hohlkolbens sind gegenüber dem 
 EMI2.2 
 --15-- umHohlkolben--13, 14-- die sich drehende   Hohlwelle --7-- während   seiner Axialverschiebungen mitnimmt. 



   Der Erfindungsgegenstand wird dadurch nicht verlassen, dass für den Drehantrieb während der Axialverschiebungen die   Hohlwelle--7--durch   eine Schraubverzahnung angetrieben ist, bei der die Gewindesteigung des ortsfesten aber drehbaren Walzenkörpers grösser ist als die des schraubverzahnten   Rades--8--.   Des weiteren liegt es im Sinne der Erfindung, dass das schraubverzahnte Rad--8--in ein ortsfestes aber drehbares Antriebsrohrstück mit Innenschraubverzahnung eingreift, wobei die Innenschraubverzahnung eine grössere Gewindesteigung aufweist als die Steigung des schraubverzahnten   Rades-8-.   



   PATENTANSPRÜCHE : 
1. Vorschubeinrichtung in einer Hämmermaschine od. dgl. mit einer das Werkstück drehenden Spanneinrichtung, die in axialer Richtung geradlinig verschiebbar angetrieben ist, dadurch ge-   kennzeichnet,   dass die Vorschubeinrichtung (13 bis 15) für das Werkstück auf der Drehachse (6) des Spannfutters (4) konzentrisch angeordnet ist.

 EMI2.1
    Similar leads -16- for the work equipment.



   It is within the meaning of the invention that the working cylinder its hollow piston - 13, 14 - and the hollow shaft - 7 - rotatably mounted in this hollow piston - and also the hammering tools - 3 - are arranged on a common axis.



   The hollow shaft --7 - and the tube - 13 - of the hollow piston are opposite the
 EMI2.2
 --15-- umHohlkolben - 13, 14-- takes the rotating hollow shaft --7-- with it during its axial displacements.



   The subject of the invention is not abandoned by the fact that for the rotary drive during the axial displacements the hollow shaft - 7 - is driven by a helical toothing, in which the thread pitch of the stationary but rotatable roller body is greater than that of the screw-toothed wheel - 8 -. Furthermore, it is within the meaning of the invention that the screw-toothed wheel - 8 - engages in a stationary but rotatable drive tube piece with internal screw-type teeth, the internal screw-type teeth having a greater thread pitch than the slope of the screw-type wheel-8-.



   PATENT CLAIMS:
1. Feed device in a hammering machine or the like with a clamping device rotating the workpiece, which is driven in a straight line displaceable in the axial direction, characterized in that the feed device (13 to 15) for the workpiece on the axis of rotation (6) of the chuck (4) is arranged concentrically.

Claims (1)

2. Vorschubeinrichtung in einer Hämmermaschine nach Anspruch 1, d a d u r c h g e k e n n - zeichnet, dass eine mit einem Drehantrieb verbundene Hohlwelle (7) an ihrem der Hämmermaschine zugekehrten Ende die Spanneinrichtung trägt, in einem doppelseitig beaufschlagten Hohlkörper drehbar gelagert ist und Axialdrucklager zwischen Hohlwelle (7) sowie Hohlkörper vorgesehen sind. EMI2.3 dass die Rohre der Hohlwelle (7) und des Hohlkörpers gegenüber dem Arbeitszylinder (15) um den Hubweg verlängert sind. EMI2.4 die Hohlwelle (7) durch eine Schraubverzahnung angetrieben ist, bei der die Gewindesteigung des ortsfesten aber drehbaren Walzenkörpers grösser ist als die des schraubverzahnten Rades (8). 2. Feed device in a hammering machine according to claim 1, characterized in that a hollow shaft (7) connected to a rotary drive carries the clamping device at its end facing the hammering machine, is rotatably mounted in a hollow body acted upon on both sides and thrust bearings between the hollow shaft (7) and Hollow bodies are provided. EMI2.3 that the tubes of the hollow shaft (7) and the hollow body are lengthened by the stroke distance in relation to the working cylinder (15). EMI2.4 the hollow shaft (7) is driven by a helical toothing, in which the thread pitch of the stationary but rotatable roller body is greater than that of the helical toothed wheel (8). EMI2.5 das schraubverzahnte Rad (8) in ein ortsfestes aber drehbares Antriebrohrstück mit Innenverzahnung eingreift, wobei die Innenschraubverzahnung eine grössere Gewindesteigung aufweist als die Steigung des schraubverzahnten Rades (8). EMI2.5 the screw-toothed wheel (8) engages in a stationary but rotatable drive tube piece with internal toothing, the internal screw-type toothing having a greater thread pitch than the pitch of the screw-toothed wheel (8).
