Definitions

  • the invention relates to a vacuum block for fixing plate-shaped workpieces on a Fixierbalken or fixing table using negative pressure, with the features of the preamble of claim 1 and a sealing plate for such a vacuum block.
  • the suction block has at least one support element on which the workpiece or the plate rests after suction and is aligned with respect to the fixing beam or the fixing table , so that they can not change their position with respect to the vacuum block.
  • the WO-A-9829218 shows a vacuum clamping system in which the vacuum blocks are equipped with anti-slip elements.
  • an exact fixation and even better alignment of the workpiece do not guarantee this vacuum block.
  • a suction head is known, provided on the clamping side elastic elevations on which the sucked workpiece is supported. But these surveys do not guarantee an exact fixation, so that the Workpiece can not be machined precisely because its location is not predictable.
  • the invention is therefore based on the object to provide a block suction, with which the workpiece can be better and more accurately positioned, on the other hand, the additional support element should be easy to produce.
  • the vacuum block according to the invention therefore four additional support elements are provided, which is arranged close to the edge and close to the sealing lip.
  • This has the advantage that a section of the plate superior to the block vacuum experiences the best possible support, which is possible with the block vacuum. Sagging of the portion of the slab projecting the block suction is thus reduced, so that the edge of the slab can be machined with greater accuracy.
  • the additional support elements are located in the area of a corner of the contact surface. In particular, projecting corner regions of the plate are relatively unstable and are supported by the additional support element of the block suction device according to the invention and aligned with the fixing bar or fixing table.
  • the support elements are located in the corner regions of the sealing plate, so that the vacuum block has equally good support properties in all directions.
  • the additional support elements have a circular cylindrical pin shape.
  • a cylindrical pin shape has the advantage that the breakthrough in the base plate may have a circular shape, so that on the one hand a simple seal is possible, on the other hand, the additional support elements are easy to produce.
  • the additional support elements are arranged distributed uniformly on the contact surface. They lie with the conventional support elements in a uniform grid, namely on parallel lines.
  • the sealing plate In order to provide a passage of the support elements through the sealing plate, the sealing plate has openings for the additional support elements. These breakthroughs are chosen so that they seal sealingly to the support elements, so that no leakage air is sucked through these breakthroughs.
  • the sealing plate has a breakthrough base plate and each breakthrough is surrounded by a bead, wherein the bead projects beyond the base plate.
  • the base plate is optimally supported by these beads against the additional supporting elements against lateral displacement, on the other hand, since the beads project beyond the additional supporting elements in the direction of the workpiece, the workpiece is held against the beads so that the workpiece is held by the beads becomes.
  • the beads consist of one elastic, compressible material, so that the protruding part of each bead is compressed as far as suction of the workpiece until the workpiece rests against the support elements.
  • the beads which consist of a slip-resistant material, with a predetermined force on the workpiece and thereby prevent slipping of the workpiece with respect to the block suction.
  • the suction chamber 24 Within the suction chamber 24 are four relatively far inboard support members 26 and four relatively far outboard additional support members 28.
  • the additional support members 28 are disposed in the immediate vicinity of the sealing lip 22 and are also in the region of each corner 30 of the seal plate 20th
  • Each additional support element is surrounded by a bead 32, which projects beyond the base plate 34 of the sealing plate 20 and also protrudes beyond the additional support element 28.
  • the bead 32 is made of an elastic, compressible material, in particular of plastic, so that it can be compressed so far during the suction of the workpiece that the workpiece can sit on the top 36 of the additional support member 28. As a result, the position of the workpiece with respect to the block suction 10 is defined.
  • seal plate 20 has next to the bead 32 further wart-like projections 38, which serve as slip-resistant elements for the workpiece.
