Description
Gegenstand der Erfindung ist eine Entlastungsvorrichtung für die Schlittenführung einer Werkzeugmaschine mit waagerecht verstellbarem Schlitten, welcher einen zweiten, lotrecht verstellbaren Schlitten, z. B. eine Arbeitsspindel, trägt, wie dies etwa bei Radialbohrmaschinen, Senkrechtfräsmaschinen und Lehrenbohrmaschinen mit verstellbarem Querbalken der Fall ist.The invention relates to a relief device for the slide guidance of a machine tool with horizontally adjustable slide, which has a second, vertically adjustable slide, e.g. B. a work spindle carries, as is the case with radial drilling machines, Vertical milling machines and jig drilling machines with adjustable crossbeams are the case.
ίο Ist das Gewicht der lotrecht verstellbaren Teile (Arbeitsspindel und Hülse) erbeblich, so wird es meistens durch ein an einer Kette aufgehängtes Gegengewicht ausgeglichen, welches hinter dem den waagerecht verschiebbaren Schlitten führenden Querbalken angeordnet ist. Bei einer solchen Anordnung trägt die waagerechte Führung nicht nur das Gewicht des Schlittens, sondern auch dasjenige des Gegengewichtes. Dementsprechend ist die Verstellbarkeit des Schlittens beeinträchtigt und die AbnutzuRg der Führung erhöht.ίο Is the weight of the vertically adjustable Parts (work spindle and sleeve) are hereditary, so it is usually caused by a chain suspended counterweight balanced behind the horizontally movable Slide leading crossbeam is arranged. In such an arrangement it bears the horizontal guide not only the weight of the sled, but also that of the counterweight. Accordingly, the adjustability of the carriage is impaired and wear and tear on the guide increases.
Gemäß der Erfindung wird das Gegengewicht nicht nur zum Ausgleich des Gewichtes der lotrecht verstellbaren Teile, sondern auch dazu verwendet, die waagerechte Führung wenigstens teilweise vom Gewicht des Schlittens zu entlasten. Es wird dies erfindungsgemäß dadurch erreicht, daß das Gegengewicht von einem am waagerecht verschiebbaren Schlitten angelenkten Hebel getragen wird, der sich auf wenigstens eine Rolle abstützt, die auf einer Bahn rollt, welche an dem die waagerechte Schlittenführung aufweisenden Teil angebracht ist. Infolge des am Hebel aufgehängten Gegengewichtes entsteht dann am Verbindungspunkt des Hebels mit dem waagerecht verschiebbaren Schlitten eine nach oben gerichteteAccording to the invention, the counterweight is not only used to balance the weight the vertically adjustable parts, but also used to at least partially reduce the weight of the horizontal guide to relieve the slide. This is achieved according to the invention in that the Counterweight carried by a lever articulated on the horizontally displaceable slide which is supported on at least one roller that rolls on a path on which the horizontal slide guide having part is attached. As a result of the counterweight suspended from the lever then an upwardly directed slide is created at the connection point of the lever with the horizontally displaceable carriage
Kraft, welche das Gewicht dieses Schlittens ausgleicht..Force that balances the weight of this sled.
Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes. Fig. ι zeigt einen senkrechten Schnitt durch den Querbalken einer Bohrmaschine mit waagerecht verschiebbarem Schlitten, der eine' lotrecht bewegliche Arbeitsspindel trägt. Fig. 2 ist ein waagerechter Schnitt längsThe drawing shows an embodiment of the subject matter of the invention. Fig. Ι shows a vertical section through the crossbar of a drill with horizontally displaceable slide, which carries a 'vertically movable work spindle. Fig. 2 is a horizontal section along its length
ίο der Linie II-II der Fig. i.ίο the line II-II of Fig. i.
Das'Gewicht der Arbeitsspindel ι und ihrer Hülse 2 wird durch ein an der Kette 4 aufgehängtes Gegengewicht 3 ausgeglichen. Die Kette 4 ist über zwei Umlenkscheiben 7 und 8 geführt, von denen die erste gleichachsig mit dem Gelenk ι ο des Hebels 9 und die zweite am freien Ende des Hebels 9 angeordnet ist. Die Scheibe 7 könnte übrigens auch anders gelagert sein. Das Gelenk 10 des Hebels 9 wird vom Spindelkopf 16 getragen.The weight of the work spindle and its The sleeve 2 is balanced by a counterweight 3 suspended from the chain 4. the Chain 4 is guided over two pulleys 7 and 8, the first of which is coaxial with the joint ι ο of the lever 9 and the second at the free end of the lever 9 is arranged. Incidentally, the disk 7 could also be mounted differently. The joint 10 of the lever 9 is carried by the spindle head 16.
Der Hebel 9 trägt eine Rolle 11, welche auf einer Bahn 12 rollt; letztere ist am Querbalken 13 angebracht, der auch die Schlittenführung 14 aufweist. Der Schlitten 15 samt dem Spindelkopf 16 ist längs der Führung 14 verstellbar.The lever 9 carries a roller 11, which rolls on a track 12; the latter is attached to the crossbeam 13, which is also the slide guide 14 has. The carriage 15 including the spindle head 16 is along the guide 14 adjustable.
Ist das Verhältnis der Abstände zwischen Scheibe 7 'und Rolle 11 einerseits, zwischen Rolle 11 und Scheibe 8 andererseits richtig gewählt, so entsteht infolge des Gegengewichtes 3 im Gelenk ι ο eine nach oben gerichtete und auf den Spindelkopf 16 wirkende Kraft, welche das Gewicht des Schlittens 15 und des Spindelkopfes 16 ausgleicht.Is the ratio of the distances between Disk 7 'and roller 11 on the one hand, between Roller 11 and disk 8, on the other hand, are correctly selected, as a result of the counterweight 3 in the joint ι ο an upward force acting on the spindle head 16, which balances the weight of the carriage 15 and the spindle head 16.
Die bauliche Anordnung der einzelnen Teile kann auch anders als dargestellt getroffen werden; so kann z. B. die Rollen nicht unmittelbar auf dem Hebel 9, sondern auf einem nicht dargestellten Zwischenstück gelagert sein, auf welchem der Hebel 9 ruht. *The structural arrangement of the individual parts can also be made differently than shown will; so can z. B. the roles not directly on the lever 9, but on one be mounted intermediate piece, not shown, on which the lever 9 rests. *
