Definitions

  • the present invention relates to a hinged wedging element for use on a workbench, machine table, vacuum table or the like.
  • a sealing system in the form of a grid or a grid is also known, described in document DE-2,258,007. It is made of rubber and undergoes compression during the suction of the part. This device therefore does not allow the precise raising of a part to a predetermined level, certain types of work are therefore not allowed. In addition, it is neither articulated nor adaptable to the shape of a part.
  • a template corresponds to a fixed part profile and it is necessary to produce a template for each new type of part, which results in significant production and material costs and a storage problem.
  • the object of the invention is to overcome all the drawbacks of the prior art.
  • the invention consists of an element of articulated wedging for use on a workbench, machine table, vacuum table or the like, characterized in that it is composed of a flexible joint comprising, for raising a piece to a predetermined height H, rigid raising elements distributed over the length of the joint and separated from each other by functional clearances allowing the wedging element to be bent.
  • enhancement elements are not limited to studs arranged in two symmetrically on either side of the flexible joint, two consecutive studs being separated by a functional gap.
  • These studs have, without limitation, a section in an isosceles right triangle with an upper groove and a lower extension, the flexible joint of which protrudes.
  • the articulated joint (1) is composed of a flexible joint (2), for example made of foam, on the flanks of which identical studs (3) are bonded, symmetrically disposed with respect to the foam joint (2).
  • the pads are arranged in groups of two face to face. Two groups of studs are separated from each other by a functional interval (7) calculated to allow the articulated joint (1) to be bent.
  • the vacuum zone is defined, chosen according to the shape of the part, by introducing it by its extensions (6) into the grooves of the table.
  • the bases (8) are supported on the upper planes of the table.
  • the lower projecting part (9) is crushed at the bottom of the groove for the lower seal.
  • the extensions (6) achieve blocking.
  • the upper projecting part (10) will be crushed by the part for the upper seal.
  • an angle such as (11) two lateral faces of two successive studs are supported one on the other thanks to their inclination at 45 ° relative to the foam seal (2).
  • studs are possible, for example studs or semicircles separated by a sufficient functional interval so that two consecutive studs of an elbow (11) are in contact with one another.
  • the grooves (5), extension (6) protruding parts (9) (10) can be eliminated and the elements for raising or studs (3) can be arranged on only one of the two lateral faces of the joint (2 ).
  • the height of the joint (2) is substantially that of the raising elements (H) of a part.
  • the articulated joint is given the shape adapted to that of the part, the surplus (12) not equipped with studs ensuring sealing on the first stud.
  • This variant can be used on a smooth metallic or magnetic table in combination with magnetic or metallic studs.
  • magnetism is used to hold the seal in place between two changes of parts and to prevent the closed area from shrinking under the effect of a vacuum supplied by the suction mouth (13).
