Definitions

  • the invention relates to a device for clamping a Workpiece on a clamping table, with one on the clamping table attachable guide shoe, which is arranged in a symmetrical arrangement the length of the guide shoe is continuous, T-groove-shaped recesses has, with a clamping claw, which acts as a rocker arm is formed and a clamping leg and a clamping leg has, and with one the clamping leg in the area of his free end penetrating clamping screw in the clamping position the clamping claw fixes relative to the guide shoe and that Clamp workpiece.
  • Such jigs are particularly in the machining of workpieces, but also in many other areas, such as when one Injection mold is clamped on a clamping table.
  • the term Workpiece is to be understood very extensively here. It can be quite generally about chip material, in particular also about tools or other parts act, which in turn during a machining operation to be used.
  • a tensioning device of the type described in the opening paragraph is known from the EP 0 391 346 B1 is known.
  • the recesses are over the length of the guide shoe provided throughout and part of a T-groove shaped cross-sectional design.
  • the clamping claw points a curved shape with the free ends of the Clamp leg and the clamping leg are arranged higher than the extensions that directly engage in the recesses.
  • the extensions have an approximately elliptical cross section Alignment of the major axis approximately in the longitudinal direction of the clamping claw on.
  • the clamping claw has an opposite of the clamping direction active return spring supported on the guide shoe, which also has the function of holding the clamping claw fulfilled after moving in the guide shoe.
  • the guide shoe on the clamping table is only a fastening screw provided, which is usually assigned a sliding block is.
  • the mounting screw is in one or more Openings arranged in the front area of the guide shoe applicable. This makes it possible to move every point of a workpiece in a space surrounding the jig to be able to tension a clamping table.
  • the clamping claw can be stepless moved in the guide shoe in the longitudinal direction and in the Clamping position can be set. Can in the vertical direction a correspondingly large height range of different heights Workpieces can be clamped, with the possibility of choosing differently cranked clamping claws in the guide shoe to use.
  • the displacement of the clamping claw in a horizontal Direction relative to the guide shoe is in such ways limited, in which the engaging in the recesses Extensions are still securely in the guide shoe.
  • this clamping device is that the displacement path of the clamping claw is limited in the guide shoe. It follows that a Workpiece only in its edge area and in the direction of its middle area only in a corresponding to the clamping leg Length is stretchable. With different heights different cranked clamping claws kept in stock and with the Guide shoe can be combined. This is complex and power clamping, for example, a workpiece in different ways high machining positions not exactly easier.
  • From CH-A-597 976 is a device for holding workpieces known, which is designed as a rocker arm clamping claw with a clamping leg and a clamping leg.
