Description

  

  Bewegliche     Klemmeinrichtung    an     Schraubstöcken,    insbesondere       Maschinenschraubstöcken.       Gegenstand vorliegender Erfindung ist eine  bewegliche Klemmeinrichtung an Schraub  stöcken, insbesondere     Maschinenschraub-          stöcken.     



  Der Erfindungsgegenstand ist auf bei  liegender Zeichnung beispielsweise darge  stellt.  



  <I>a</I> und<I>b</I> sind die     Klemmbackenträger,     <I>(a</I> im Schnitt,<I>b</I> in Ansicht), die sich durch  die Spindel     c    mit Links- und Rechtsgewinde  auf dem Schlitten d     öffnen    und schliessen  lassen. e und f' sind die Klemmbacken, die  an den schiefen     Backenträgerflächen        g    und h  anliegen. Mit i ist eine Schraube bezeichnet,  die die Klemmbacke mit dem Klemmbacken  träger verbindet.

   Der schraffierte Querschnitt  k zeigt die nach unten und oben erweiterte  Bohrung im     Klemmbackenträger,    so     dass    sich  die Schraube i in vertikaler Richtung be  wegen kann.     l    ist eine Spiralfeder, die in       entspreehendenVertiefungen    im Klemmbacken  träger und der Klemmbacke lagert und die  Klemmbacke nach oben drückt.

   Wird nun    ein Werkstück durch Anziehen der Spindel  c zwischen die Klemmbacken<I>a</I> und<I>b</I> ein  gespannt, so bewegen sich diese bei zu  nehmender Pressung auf den schiefen Flächen       g    und     1z    zwangsweise nach unten, wobei trotz  eventuellem Spiel     zwischem        Klemmbacken-          trägern    und Schlitten d dar Werkstück  zwangsweise auf den Schlitten d     aufzuliegen     kommt.



  Movable clamping device on vices, in particular machine vices. The subject of the present invention is a movable clamping device on screw sticks, in particular machine vices.



  The subject of the invention is illustrated in the accompanying drawing, for example.



  <I> a </I> and <I> b </I> are the jaw supports, <I> (a </I> in section, <I> b </I> in view) that run through the spindle Open c with left and right-hand thread on slide d and let it close. e and f 'are the clamping jaws that rest against the inclined jaw support surfaces g and h. With a screw i is referred to, which connects the jaw with the jaw carrier.

   The hatched cross-section k shows the bore in the jaw support, which is widened downwards and upwards, so that the screw i can move in the vertical direction. l is a spiral spring, which is supported in corresponding recesses in the clamping jaw carrier and the clamping jaw and presses the clamping jaw upwards.

   If a workpiece is now clamped between the clamping jaws <I> a </I> and <I> b </I> by tightening the spindle c, these will move forcibly downwards with increasing pressure on the inclined surfaces g and 1z , whereby despite any play between the clamping jaw carriers and the slide d, the workpiece is forced to rest on the slide d.

Claims (1)

PATENTANSPRUCH: Bewegliche Klemmeinrichtung an Schraub stöcken, insbesondere Maschinenschraub stöcken, gekennzeichnet durch schräg nach einwärts gegen die Unterlage gerichtete Auf lageflächen an den Klemmbacken und Klemm backenträgern, wodurch beim Einspannen eines Werkstückes und bei zunehmender Pressung das Werkstück unter Überwindung einer entgegenwirkenden Kraft automatisch gegen die die Klemmbackenträger tragende Unterlage gedrückt wird. PATENT CLAIM: Movable clamping device on vices, in particular machine vices, characterized by bearing surfaces on the clamping jaws and clamping jaw carriers that are inclined inwards against the base, whereby when a workpiece is clamped and with increasing pressure, the workpiece is automatically counteracted by overcoming an opposing force Jaw carrier supporting pad is pressed.
