Definitions

  • the invention relates to an element system according to the preamble of claim 1.
  • the device base plate has intersecting, grid-shaped T-grooves which serve to receive a T-nut with an internal thread.
  • the constricted area of the T-groove facing upward is not only intended for the passage of the screw, but is also designed as a fitting groove.
  • the clamping part resting on the support surface of the device base plate has on its lower support surface a T-groove arranged mirror-inverted to the first-mentioned T-groove.
  • a precisely fitting double T-nut is inserted into the adjacent, aligned T-slots.
  • the double T-nut is split and the parts are pulled together by a common connecting screw.
  • the stability of this connection is essentially determined by the strength of the screw connection.
  • the double T-nut as a fitting and tensioning element must have the shear forces in X- or record the Y direction.
  • the more connections of this type are contained in a device structure, the greater the accuracy errors and stability losses.
  • Another major disadvantage of the known device is that the accessibility of the connecting elements requires bores and grooves which are used exclusively for fastening the device parts to one another.
  • the workpiece or device carriers constructed in this way are limited in their usability because of the necessary recesses.
  • the object of the invention is to create an element system which is very variable and allows the clamping part to be fixed easily and reliably without the aid of screws in the X-Y plane.
  • This object is achieved in that the distance between reference surfaces of adjacent elevations corresponds to the distance between the reference surfaces of an elevation or is an even multiple thereof.
  • elevations are polygonal, preferably square, in plan view.
  • FIG. 1 shows a perspective illustration of a base part with elevations regularly arranged thereon in a grid
  • FIG. 2 shows a top view of the base part with a special complementary clamping part
  • FIG. 3 shows a section along plane III-III according to FIG. 2,
  • Figure 4 - a plan view " of a base part with clamping part in an exemplary fixing position.
  • a base part 1 On a base part 1, cube-shaped elevations 6 arranged in a regular grid are provided. The elevations have lateral reference surfaces 6a and 6b and an upward one reference surface 6c pointing in the Z direction. The reference surface 1 a of the base part 1 extends parallel to the reference surface 6 c.
  • the distance a between two opposing reference surfaces 6a and 6b of the same elevation 6 corresponds in the illustrated embodiment to the distance b between the reference surfaces of adjacent, different elevations 6.
  • Designated by 2 is a tensioning part which has a base region from which elevations 12 extend in the Z direction.
  • the elevations 12 of the clamping part 2 have two reference surfaces 2a and 2b running parallel to each other at each elevation. With 12c the bearing surface of the survey is designated.
  • the contact surface 12c lies on the reference surface 1a.
  • the distance b between the reference surfaces 12a and 12b provided on the same elevation 12 and opposite each other corresponds to the distance a in the exemplary embodiment shown.
  • Figure 4 shows a fixation of the clamping part 2 on the base part 1.
  • the back surface 2a of the clamping part 2 faces upwards.
  • the clamping part 2 is fixed in the position shown with the help of four wedges 3 and 4 and with the help of shims 5.
  • the fixation in the X direction takes place via the mentioned clamping wedges and inserts, the fixation in the Y direction results from the fact that the distances a and b on the elevations 6 and 12 correspond to one another.

Abstract

Un système d'éléments pour la constitution de dispositifs de serrage comporte une pièce de base (1) s'étendant dans un plan X-Y, et au moins une pièce de serrage (2) pouvant être fixée sur la pièce de base en différentes positions sélectionnables. La pièce de base (1) possède dans le plan X-Y des proéminences (6) disposées régulièrement selon une trame avec des faces de référence (6a et 6b) agissant dans le sens Z. Le cas échéant, des éléments de fixation s'étendent entre les proéminences (6) et la pièce de serrage (2). Soit la distance entre des faces de référence de proéminences voisines et la distance des faces de référence sur une proéminence est égale, soit la distance entre des faces de référence de proéminences voisines est un multiple pair de la distance des faces de référence sur la même proéminence. On obtient ainsi une grande souplesse d'utilisation du système d'éléments, tout en ayant des possibilités de serrage fiables et faciles.
