Description

Die Erfindung bezieht sich auf einen Schraubstock mit je paarweise zusammenarbeitenden, auf Achsen. von schwenkbaren Doppelhebeln- schwenkbar angeordneten Spannbacken, die umsteckbar und außermittig gelagert sind und das Einspannen beliebig gestalteter Werkstücke gestatten. Nun kommen, jedoch Werkstücke vor, die vielfach wiederkehren, von denen also Serien zu bearbeiten sind, so daß bestimmte vorgeschriebene Stellungen der Spannbacken erwünscht sind" z. B. Schraubenbolzen und Muttern mit Vier- oder Sechskantköpfen.The invention relates to a vice with each working in pairs on axes. of pivotable double levers pivotably arranged clamping jaws, which can be repositioned and are mounted eccentrically and which allow workpieces of any shape to be clamped. Now, however, there are workpieces that recur many times, of which series are to be machined, so that certain prescribed positions of the clamping jaws are desired, for example screw bolts and nuts with square or hexagonal heads.

Um für solche Werkstücke das Einstellen und Ausrichten der Spannbacken am Schraubstock zu vereinfachen, und zu erleichtern, haben gemäß der Erfindung die Spannhacken jedes auf demselben Schwenkhebel gelagerten Backenpaares in verschiedenem Winkel zu ihrer Längsachse verlanfende Flanken. Diese kommen an! 4en #Grenzlagen mit einem mittleren Stein, ihr-es gemeinsamen Schwenkhebels zum Anschlag. Bei entsprechender Wahl der FlankenwinIkel der Spannbacken und der Flankenwinkel des Steines läßt sicherreichen, daß die Spannbacken. z. B. in einem Winkel von go oder auch i:2o9 zueinander stehen, so daß im erstere#n, Fall Vie-rkantköpfene#bst Muttern oder im anderen Fall Sechskantköpfe nebst Muttern, ohne zeitraubendes Probieren, eingespannt werden, können.To adjust and align the clamping jaws for such workpieces To simplify on the vice, and to facilitate, have according to the invention Clamping hooks of each pair of jaws mounted on the same pivot lever in different ways Flanks requesting an angle to their longitudinal axis. These arrive! 4en #Boundaries with a middle stone, ye-es common swivel lever to the stop. With the appropriate Selection of the flank angle of the clamping jaws and the flank angle of the stone can be safely that the jaws. z. B. are at an angle of go or i: 2o9 to each other, so that in the first case, square heads, nuts or in the other case hexagonal heads together with nuts, without time-consuming trial and error, can be clamped.

Die Zeichnung stelltein Ausführungsbeispiel der Erfindung im waagerechten Schnitt durch den Schrau-bstock mit teilweiser Draufsicht dar.The drawing represents an embodiment of the invention in the horizontal Section through the vice with a partial top view.

Am Schraubstockgestell a sind die beiden SchwenkhebeIf um mittlere Bolzen e schwenkbar auf den Einstellkloben d geführt, die sich in, bekannter Weise mittels einer Schraubenspindel gegeneinander bewegen lassen. An den Schwenkhebeln f sind die Spannbacken li um Bolzen g schwenkbar. Die Flankenwinkel der Backen h sind verschieden. Im gezeichneten, Beispiel verlaufen die Flanken h' parallel zur Längsachse z-.- der Spannbacken h, die gegenüberliegenden Flanken Y' dagegen unter einem Winkel von 15' zur Achse z-z.On the vice frame a, the two pivoting levers are guided so as to be pivotable about central bolts e on the setting clamps d , which can be moved against one another in a known manner by means of a screw spindle. On the pivot levers f , the clamping jaws li can be pivoted about bolts g. The flank angles of the jaws h are different. In the example shown, the flanks h 'run parallel to the longitudinal axis z -.- of the clamping jaws h, while the opposite flanks Y' run at an angle of 15 ' to the axis zz.

Die Schwenkhebel f sind auf den festen Bolzen; c mit einem mittleren Stein i gelagert, der quadratisch gehaltenist bei diagonaler Stellung des Quadrates zur Längsachse des Schraubstocks, so daß die Flankenwinkel des Steines zur Längsachse des Schraubstocks unter 45' verlaufen. Werden die Spannbackenh so eingeschwenkt,- daß sie mit ihr#en- paraltelachsig verlaufenden Flanken h' mit ihrem zugehörigen Stein i zum Anschlag kommen, wie in der Abbildung linikst dargestellt, .dann bilden die Spannbackeen einen Winkel von gro9. Alle vier Spannbacken können demgemäß quadratische Werkstücke einspannen. Werden die Spannbacken h auf die andere Seite geschwenkt mit gleichzeitiger Schwenkung ihres Hebels f um i8o,', wie in der Abbildung rechts dargestellt, dann bilden. sie einen Winkel von i2o', wenn sie mit ihren Flanken, h"' am Stein- i anliegen. Es k#5n#nen also Sechskantwerkstücke eingespannt werden. Die An#schlagwinkel können auch abweichend von den dargestellten Graden sein, sofern mehr spitze oder auch mehr st-umpfwinklige Werkstücke serienweise zu,r Einspannung kommen. Dazu kann der Stein i auswechselbar sein. Solche Schraubstöcke sind dann zweckmäßig, wenn es sich um die Bearbeitung einer großen Anzahl derselben Werkstücke handelt. Die beschriebene Ausführung des Schraubstocksermöglicht die doppelseitige Lagerung der Spannbacken- in, ihren Schwenkhebeln, f, so daß einsqeitige Beanspruchungen der Lagerbolzen g auf Biegung vermieden werden. Das,selbe gilt für die Lagerbolzen e der Schwelik:hebel f. The pivot levers f are on the fixed bolt; c supported by a central stone i which is held in a square shape with the square in a diagonal position to the longitudinal axis of the vice so that the flank angles of the stone to the longitudinal axis of the vice extend at 45 '. If the clamping jaws are swiveled in such a way - that they come to a stop with their flanks h 'running parallel to the axis with their associated stone i, as shown in the figure, the clamping jaws form an angle of large. Accordingly, all four clamping jaws can clamp square workpieces. If the clamping jaws h are swiveled to the other side with simultaneous swiveling of their lever f by i8o, ', as shown in the figure on the right, then form. they have an angle of i2o 'when their flanks' h "' are in contact with the stone i. Thus, hexagonal workpieces can be clamped. The stop angles can also deviate from the degrees shown, provided that they are more pointed or Also, more straight-round workpieces come in series, r clamping. In addition, the stone i can be interchangeable. Such vices are useful when machining a large number of the same workpieces. The described design of the vise enables the clamping jaws to be supported on both sides - in, their pivot levers, f, so that one-sided stresses on the bearing pin g on bending are avoided. The same applies to the bearing pin e of the Schwelik: lever f.
