Description
Spannvorrichtung für den Vor- und Rückwärts-Gang einer Schraubstockbacke mit Druck-'und Haltelager Es sind Schraubstöcke mit Spindeln, die in verschiedenen Arten gelagert sind, bekannt.Clamping device for moving a vice jaw forwards and backwards with pressure and holding bearings There are vices with spindles that come in different Species are stored, known.
Die Lagerungen haben jedoch den -Nachteil, daß die Spindeln sich leicht in denselben festfressen und für den Vor- und Rückwärtsgang der beweglichen Backe zu schwer gehen.However, the bearings have the disadvantage that the spindles are easy seize in the same and for the forward and reverse gear of the movable jaw to go too hard.
Bei der Erfindung ist der Nachteil dadurch behoben, daß sich die Spindel fast ohne Reibung gegen eine im Loch der Backe sitzende Kugel legt. Der Spindelkopf ist zur Kugelseite hin vorzugsweise konvex ausgebildet, so daß Räume für eine gleichzeitige vorteilhafte Sparschmierung entstehen. In diese Räume wird Fett o. dgl. eingebracht, welches eine Schmierreserve bildet. Das Fett wird durch Betätigung der Spindel und der sich dadurch drehenden Kugel sparsam an die Reibungsstellen verteilt.In the invention, the disadvantage is eliminated in that the spindle almost without friction against a ball seated in the hole of the cheek. The spindle head is preferably convex to the ball side, so that spaces for a simultaneous advantageous economy lubrication arise. Grease or the like is introduced into these spaces, which forms a lubricant reserve. The fat is removed by operating the spindle and the rotating ball sparingly distributed to the friction points.
Eine weitere Einrichtung ist für den Rückzug der Spindel auch durch eine Kugel mit Sparschmierung vorgesehen.Another facility is through for the retraction of the spindle as well a ball with economy lubrication is provided.
Die Kugel sitzt m einem Gehäuseloch und wird durch eine Schraube regulierbar in eine Kugelnute an der Spindel eingestellt. Da die Kugel ein Stück iin Kugelloch und in der Kugelrille sitzt, wird die Spannbacke auch jetzt bei geringster Reibung mitgenommen. In die Hohlräume der Kugelumgebung und nötigenfalls in die Rille des Spindclkopfes wird auch zur Schmierung und zur Verhinderung der Reibung Fett o..dgl. eingebracht. Jetzt ist der Vor- und Rücktransport der Backe,durch die Spindel und ,m:it der geringsten Reibung, nämlich durch den Einbau der Kugeln und der Sparscbmierungen, erreicht.The ball sits in a hole in the housing and can be adjusted with a screw set in a ball groove on the spindle. Because the ball is a piece in a ball hole and sits in the ball groove, the clamping jaw is now even with the slightest friction taken away. In the cavities around the sphere and, if necessary, in the groove of the Spindclkopfes is also used for lubrication and to prevent friction, grease or the like. brought in. Now the jaw is transported back and forth, through the spindle and , with the least amount of friction, namely through the installation of the balls and the fuel-saving lubrication, achieved.
Auf der Zeichnung ist ein Ausführungsbeispiel dargestellt, und zwar zeigt: Abb. x einen Schraubstock mit einer geführten Backe und Abb. -#., einen Querschnitt der _l#Mb. i nach Linie II-II.In the drawing, an embodiment is shown, namely shows: Fig. x a vice with a guided jaw and Fig. - #., a cross section the _l # Mb. i to line II-II.
Die bewegliche Backe a wird seitlich an einen Rahmen b geführt, der dadurch einen Durchgang c für die einzuspannenden Stücke hat. Die Führungsbewegung wird durch die Spindel j erzeugt, indem vor der Spindel t eine .Kugel lt angeordn°2t ist, die 1a wieder in einem Loch der beweglichen Backe a sitzt. Weiter ist eine Kugel t: am Spindellials h so angeordnet, daß dieselbe i teils in der Spindel t tmcl teils im Kugellocli g liegt. Das Kugelloch g kann durch die Schraube l versclilosscn und durch letzte l kann zugleich die Kugel i für ihre fastreibungslose Tätigkeit eingestellt werden. Zugleich können die Hohlräume in an den Kugeln lt. und i. und an der Hohlrille: p mit Fett o. dgl. gefüllt werden, so daß eine Fettreserve für die wenig Fett brauchenden Kugeln vorhanden ist.The movable jaw a is guided laterally to a frame b, which thereby has a passage c for the pieces to be clamped. The transfer movement is produced by the spindle j, t by a .Kugel lt angeordn ° 2t, 1a is back in a hole of the movable jaw a front of the spindle. Furthermore, a ball t: is arranged on the spindle axis h in such a way that the same i lies partly in the spindle t tmcl and partly in the Kugellocli g. The ball hole g can be closed by the screw l and the last l can also be used to adjust the ball i for its almost frictionless activity. At the same time, the cavities in on the balls lt. And i. and at the hollow groove: p can be filled with fat or the like, so that there is a fat reserve for the balls that require little fat.
