Definitions

  • Clamping element with two parallel guided clamping jaws for position-flexible Clamping of workpieces, in particular for supporting the workpieces in their predetermined clamping position at any point.
  • clamping elements For clamping workpieces clamping elements are used, the Position the workpiece in position. Labile and longer workpieces require more Clamping units, by means of which it determines position at all critical points get supported. These clamping elements must be applied to the workpiece after this is already stated in its position. The introduction such clamping units must be made so that the workpiece at the points which the clamping units come to rest, is not distorted or deformed. This high demands are placed on such clamping elements.
  • Clamping elements are usually operated hydraulically. The hydraulic pressure is introduced so that the clamping element his jaws toward each other or moved away from each other. Disagreements in the hydraulics or in the Friction surfaces that affect the moving parts can easily become too Lead tensions of the workpieces.
  • labile places to the most diverse workpieces be stabilized with one element.
  • the invention is thus a clamping element with two flexibly movable, parallel arranged sliders on which the jaws are placed. At the Clamping put the jaws posotionsix pliers like the Workpiece. Thus, two equally large opposing contact forces act at two opposite points on the workpiece. These two Touching forces are similar in their effect according to the principle of action Reaction to and thus do not lead to deformation or tension of the Workpiece.
  • the plunger 9 u. 10 are in the piston plates 15; 16 arranged so that the from them outgoing force directly on the end faces 17; 18, the slider 2; 3 is initiated in this.
  • the sliders are running smooth and even in their guide surfaces and transmit the power directly to the clamping point 19 and the workpiece 20 without this deform.
  • the result is the workpiece 20 equal oppositely directed forces after the principle action equal reaction.
  • the resulting load moment - Clamping force x lever arm a - is determined by the guide surfaces within the recess 4; 5 recorded, wherein the recess 4; 5 with their guide surfaces in about the housing length corresponds. These relatively large guide surfaces help that the frictional forces are kept as low as possible.
  • a piston 22 for setting intended In the housing 1 is below the recess 4, 5 a piston 22 for setting intended.
  • This piston 22 is driven separately. He is at his head end provided with a dovetail-shaped wedge piece 23, the exact in an im Slider 2, 3 recessed recess 6 is fitted, in such a way that in relaxed state, the slider 2; 3 on the wedge piece 23 without contact slide past. The leadership of the slide takes place at the contact surfaces in the Recesses 6.
  • the piston 22 is acted upon by the hydraulic connection 25. Its return takes place by means of associated disc springs 24. Die If necessary, provision can also be made hydraulically.
  • the piston 22 is acted upon by hydraulic connection 25.
  • This piston will thereby pulled down into the housing 1.
  • the trained as a wedge piece 23 head is pulled down in the recess 6 and presses on the Side surfaces of the recess 6.
  • the Clamping element is set so that it is independent of external forces as well with pressure drop in the hydraulics remains in its position and thus acts self-locking, this is due to the configuration of the wedge piece 23rd causes.
