Description

Schnellspannvorrichtung für Parallelschraubstöcke. Gegenstand der Erfindung ist eine Weiterbildeng der im Patent 336765 beschriebenen Schnellspannvorrichtung für Schraubenschlüssel, Schraubstöcke u. dgl.Quick clamping device for parallel vices. Subject of The invention is a further development of the quick release device described in patent 336765 for wrenches, vices, etc.

Die Neuheit besteht darin, daß bei einem Parallelschraubstock das zur Schnellstellung in bekannter Weise unterbrochene Gewinde der festliegenden Backe mit einer zwischen zwei Anschlägen beweglichen Schraubspindelmutter so in, Eingriff steht, daß die beim Entspannen freigegebene bewegliche Backe beim Spannen unbegrenzt stark angezogen werden kann.The novelty is that with a parallel vice the for quick setting in a known manner interrupted thread of the fixed jaw with a screw spindle nut movable between two stops so engages it says that the movable jaw released during relaxation is unlimited during tensioning can be strongly attracted.

Auf der Zeichnung ist,ein Ausführungsbeispiel -des Schnellspann-Parallelschraubstockes in den Fig. i und 2 im senkrechten Längsschnitt, teilweise in Ansicht und im senkrechten Querschnitt nach Linie E-F veranschaulicht.The drawing shows an embodiment of the quick-release parallel vice in Figs. i and 2 in vertical longitudinal section, partially in view and in the vertical Cross-section along line E-F illustrated.

15 ist die feststehende und 16 die bewegliche Backe des Schraubstockes. Die mit beiderseits unterbrochenem Muttergewinde versehene Hülse io ist mit der feststehenden Backe 15 durch den versenkt liegenden Flansch 17 verschraubt. Die in der beweglichen Backe 16 drehbar, aber nicht verschiebbar angeordnete Scbraubspindel 2 sitzt mit ihrem Gewinde x in der Mutter 7 (Zwischenglied). Die Bewegung der Spindel 2 im Zwischenglied 7 wird durch die Anschläge 5 und 6 begrenzt. Das .doppelseitig unterbrochene und mit Anschlagleiste 7a versehene Außengewinde 8 des Zwischengliedes findet ebenso wie beim Schraubenschlüssel gleichunterbrochenes Metergewinde 9 in der Hülse io vor.15 is the fixed jaw and 16 is the movable jaw of the vice. The sleeve, which is provided with a nut thread interrupted on both sides, is connected to the fixed jaw 15 screwed through the recessed flange 17. the in the movable jaw 16 rotatably, but not displaceably arranged screw spindle 2 sits with its thread x in the nut 7 (intermediate link). The movement of the spindle 2 in the intermediate member 7 is limited by the stops 5 and 6. That .double-sided interrupted external thread 8 of the intermediate link provided with a stop bar 7a As with the wrench, there is an equally interrupted meter thread 9 in the sleeve before.

Die Wirkung beim Öffnen und Schließen des Schraubstockes sowie das Einspannen und Entspannen des Werkstückes ist genau dasselbe wie beim Schraubenschlüssel, nur daß beim Schraubstock die Spinde12 gedreht wird und die Hüls- io festliegt, während dies beim Schraubenschlüssel umgekehrt ist.The effect of opening and closing the vice as well as that Clamping and releasing the workpiece is exactly the same as with a wrench, only that the spindle 12 is rotated in the vice and the sleeve is fixed, while this is the other way around with the wrench.

Wird die Spindele nach der einen oder anderen Richtung gedreht, so wird das, Zwischenglied 7, sobald der eine oder andere der Spindelanschläge 5, 6 an ihr angelangt sind, mitgenommen. Bei weiterer Drehung der Spindel 2 gelangt das Außengewinde 8 des Zwischengliedes 7 mit dem Muttergewinde 9 der Hülse io außer Eingriff und die bewegliche Backe 16 kann dann samt Spindel 2 und Zwischenglied --7 innerhalb bestimmter Grenzen vor und zurück geschoben, d. h. auf jede beliebige Spannweite eingestellt werden.If the spindle is turned in one direction or the other, so becomes the, intermediate member 7 as soon as one or the other of the spindle stops 5, 6 arrived at her, taken away. If the spindle 2 is rotated further, this occurs External thread 8 of the intermediate member 7 with the nut thread 9 of the sleeve io except Engagement and the movable jaw 16 can then together with the spindle 2 and intermediate member --7 pushed back and forth within certain limits, d. H. on any Span can be adjusted.

Das Festspannen- oder Entspannen des Werkstückes bzw. die Feineinstellung der Spannbacken des Schraubstockes erfolgt durch Rechts- oder Linksdrehen der Spindel2, wodurch das Zwischenglied? mit dem Gewinde 9 der Hülse io wieder in Eingriff gebracht und bis zu seiner Anschlagleiste 7a mitgenommen wird., worauf, weil die Mutter 7 stehenbleibt, die Längsbewegung der Spindel 2 und damit der beweglichen Backe 16 einsetzt und so das beabsichtigte Festspannen 1 oder Entspannen des Werkstückes bzw, die-Feineinstellung der Spannbacken. erfolgt.The clamping or releasing of the workpiece or the fine adjustment the clamping jaws of the vice are made by turning the spindle 2 clockwise or counterclockwise, whereby the pontic? brought into engagement again with the thread 9 of the sleeve io and is taken up to its stop bar 7a, whereupon, because the nut 7 the longitudinal movement of the spindle 2 and thus of the movable jaw 16 stops begins and so the intended clamping 1 or relaxation of the workpiece or the fine adjustment the jaws. he follows.

Das unterbrochene Muttergewinde 9 kann auch unmittelbar in der feststehenden Backe , 15 angeordnet sein, unter Wegfall der Hülse ro.The interrupted nut thread 9 can also directly in the fixed Jaw, 15 be arranged, eliminating the sleeve ro.
