Definitions

  • the invention relates to a clamping jaw according to the preamble of claim 1 and to a clamping element for use in such Spannbache according to claim 5.
  • a jaw with the features of the preamble of claim 1 is for example from the US 2010/0230884 A1 known.
  • the clamping elements are arranged at a clamping height of about 10 millimeters in order to be able to transfer sufficient clamping forces on the workpiece at all. Consequently, the workpiece is damaged at this clamping height.
  • the clamping height is meant by a lower edge of the workpiece to the highest level clamping height.
  • From the AT 389270 B is to take a clamping device, which has two successive deliverable jaws. On the top of the jaws triangular clamping elements are provided. Adjacent mutually extending clamping elements form with their workpiece facing end face a common plane.
  • clamping elements have a clamping surface on which no mandrels, clamping pins or the like. Worked or formed, so that only a frictional operative connection between the clamping elements and the workpiece to be clamped arises.
  • Spannbachen are for example from the WO 99/52678 A1 , of the JP 2002 219626 A , of the DE 21 34 401 A1 , of the EP 2105 257 A2 , of the DE 197 56 793 A1 , of the DE 20 2009 016 994 U1 , of the US 2002/0056955 A1 as well as from the EP 2 070 655 A2 known.
  • the clamping elements With the help of the clamping elements, a uniform course of notches in the workpiece produced so that the workpiece engage identically formed mandrels and clamping elements in the already existing indentations in order to fix the workpiece on several different machine tools in exact previous position, without further indentations in the workpiece are necessary.
  • the expended clamping force to be transferred to the workpiece so that the clamping elements are held as free of play on the jaw and therefore do not slip or rotate when reaching the operative contact with the workpiece.
  • the recesses in the jaw has a triangular inner contour and in that the tip of the recess is remote from the clamping surface, can be used without clearance in the recess adapted to this clamping element, so that when generating the clamping force, the clamping element with the penetrate these projecting mandrels into the workpiece, wherein the clamping element is pressed against the two, for example, at an angle of 60 ° to each other extending side walls of the recess, whereby the clamping force is transmitted evenly from the clamping element on the clamping jaw.
  • a correspondingly high clamping force is required and, on the other hand, a plurality of clamping mandrels are integrally formed or attached to the workpiece facing end side of the clamping elements, which come selectively in operative contact with the workpiece and penetrate into this when the Infeed movement and the clamping force defined is specified.
  • the mandrels are designed as a body in trapezoidal shape and positioned to each other and designed so that they are adapted to the material from which the workpiece is made.
  • the arrangement of the mandrels on the workpiece facing end surface of the clamping elements is advantageously arranged uniformly such that a Variety of notches in the workpiece in the axial and longitudinal direction arises.
