Description
Schraubstock mit Druck- und Haltelager für die an der beweglichen Schraubstockbacke angeordnete Spindel. Gegenstand vorliegender Erfindung ist ein Schraubstock mit Druck- und Haltelager für .die an der ,Schraubstockbacke angeord nete Spindel.
Auf der Zeichnung ist ein Ausführungs beispiel dargestellt, und zwar zeigt: Fig. 1 einen Parallelschraubstock, Fig. 2 einen Querschnitt nach Linie II-II der Fig. 1 in grösserem Mass:stabe. Bei der dargestellten Ausführungsform ist die bewegliche Schraubstockbacke a seit lich an einem Rahmen b verschiebbar ge führt. Ein einzuspannendes Werkstück wird zwischen die feste Backe a' und die beweg liche Backe a eingelegt und durch Verschie ben der Backe a eingespannt.
Die Bewegung der Backe a erfolgt .durch die Schrauben- @spindel t. Derselben ist eine Kugel zentral vorgelagert, die in einer Bohrung der beweg- liehen Backe a sitzt. Weiter ist eine zweite Kugel i so, angeordnet, dass sie mit Spiel teils in eine entsprechend geformte Ringrille der Spindel t und teils in .eine Bohrung g ein- tritt. Die Bohrung g ist durch .die Schraube l verschliessbar. Die Hohlräume m um die Kugeln h und i und in der Ringrille sind mit Fett oder .dergleichen gefüllt und bilden ein Dauerschmierlager.
Beim Vorschieben der Backe a drückt Spindel<I>t</I> auf die Kugel h, während Kugel<I>i</I> beim Rückgang,der Spindel t wirksam wird. Diese Ausbildung gestattet eine Verminde rung der Reibung.
Vice with pressure and holding bearing for the spindle arranged on the movable vice jaw. The subject of the present invention is a vice with pressure and holding bearings for .the on the vice jaw angeord designated spindle.
In the drawing, an exemplary embodiment is shown, namely: Fig. 1 shows a parallel vice, Fig. 2 shows a cross section along line II-II of Fig. 1 on a larger scale: rod. In the illustrated embodiment, the movable vice jaw a since Lich on a frame b leads ge. A workpiece to be clamped is inserted between the fixed jaw a 'and the movable jaw a and clamped by moving the jaw a.
The jaw a is moved by the screw @spindle t. A ball is located in front of it and sits in a hole in the movable jaw a. Furthermore, a second ball i is arranged in such a way that it enters, with play, partly into a correspondingly shaped annular groove of the spindle t and partly into a bore g. The hole g can be closed by the screw l. The cavities m around the balls h and i and in the annular groove are filled with grease or the like and form a permanent lubrication bearing.
When the jaw a is advanced, the spindle <I> t </I> presses on the ball h, while the ball <I> i </I> takes effect when the spindle t retracts. This training allows a reduction in friction.
