Description

Die den Gegenstand des Patents 637649 bildende Vorrichtung bezweckt den selbsttätigen Vorschub bei Bohrmaschinen. Der Bohrdruck wird erzeugt durch den druck-"speichernden Körper d. Dieser stützt sich mit einem Ende gegen das Maschinengestell und mit dem anderen Ende gegen den an der Bohrspindel befestigten Teil h. Da der Teil h fest mit der Bohrspindel & verbunden ist,The device forming the subject of patent 637649 is intended for automatic feed in drilling machines. The drilling pressure is generated by the pressure "storing body d. One end of this is supported against the machine frame and the other end against the part h attached to the drilling spindle. Since part h is firmly connected to the drilling spindle &,

ίο wird der Druck von h auf b weitergeleitet. Beim Vorrücken des Bohrers entspannt sich der Druckkörper und bringt den Teil h in Verbindung mit dem Teil e1 der Haltevorrichtung e, f, g. Durch den entstehenden Kraftschluß zwischen h und e1 schraubt die Bohrspindel b die Haltevorrichtung e, f, g im Maschinengestell hinab, bis sich der Kraftschluß wieder löst. Da dieser Vorgang sich dauernd wiederholt, erfolgt eine selbsttätige Nachspannung der Halteeinrichtung.ίο the pressure is passed on from h to b. As the drill advances, the pressure body relaxes and brings part h into connection with part e 1 of the holding device e, f, g. Due to the resulting frictional connection between h and e 1, the drilling spindle b screws the holding device e, f, g down in the machine frame until the frictional connection is released again. Since this process is repeated over and over, the holding device is automatically re-tensioned.

Bei der neuen Ausführung nach Fig. 1 ist als druckspeichernder Körper wieder eine Schraubenfeder d gewählt worden. Wie beiIn the new embodiment according to FIG. 1, a helical spring d has again been selected as the pressure-storing body. As in

. der vorher beschriebenen Bauart wirkt der Federdruck auf den Teil W- ein. Der Teil h2 ist mit der Bohrspindel b auf Drehmitnahme gekuppelt, kann aber auf diese keinen Druck übertragen, da h2 axial in & verschieblich ist. Der Teil Ψ bleibt daher dauernd in Verbindung mit e1. . of the type described above, the spring pressure acts on part W- . The part h 2 is coupled to the drilling spindle b for rotational driving, but cannot transfer any pressure to it, since h 2 can be moved axially in &. The part Ψ therefore remains permanently in connection with e 1 .

Durch den dadurch erzeugten Kraftschluß schraubt die Bohrspindel b die Haltevorrichtung e, f, g in der Vorschubrichtung vor. Dabei drückt der Teil 01 der Haltevorrichtung auf den Teil b1 der Bohrspindel. Zwischen bl und e1 kann ein Drucklager m eingeschaltet werden. Die Bohrdruckstärke ergibt sich aus der Größe des Kraftschlusses zwischen h2 und e1 und wird durch entsprechende Spannung des Druckkörpers d- eingestellt.As a result of the frictional connection generated in this way, the drilling spindle b screws the holding device e, f, g forward in the feed direction. The part 0 1 of the holding device presses on the part b 1 of the drilling spindle. A thrust bearing m can be switched on between b l and e 1. The strength of the drilling pressure results from the size of the frictional connection between h 2 and e 1 and is set by the corresponding tension of the pressure body d- .

Fig. 2 zeigt die gleiche Bauart, aber mit anders gestalteter Mitnehmereinrichtung. Der Teil hs hat eine ebene Stirnfläche, außerdem ist ein Reibungsbelag vorgesehen.Fig. 2 shows the same design, but with a differently designed driver device. The part h s has a flat end face, and a friction lining is also provided.
