Definitions

  • the present invention relates to a support part for the precise placement of several workpieces to be clamped together between two clamping jaws or the like for their processing by means of machine tools, and to the use of the support part for the precise clamping of individual bundles or flat parts to be machined in height.
  • the clamping is complicated because the parts to be machined can fall down between the platelets and the movable jaw, for example a vice or a clamping jaw, during the clamping, in particular if the parts to be machined are thin. Because of the necessary clamping movement of the clamping jaws, these known support parts cannot have the width corresponding to the distance between the clamping jaws necessary for inserting the workpieces. A large number of differently wide support parts (depending on the thickness of the workpiece bundle to be clamped) is therefore necessary.
  • the object of the present invention is to provide support parts which are required in fewer numbers and which also prevent the disadvantage of the uncertainty when clamping, namely that an object to be processed does not get into the correct position.
  • This object is achieved according to the invention in the case of a support part of the type mentioned at the outset in that the support part is a corrugated, resilient band, the underside of which is formed by a corrugated side edge running transversely to the tensioning direction.
  • Such a support part allows the parts to be clamped and machined to be supported during the entire clamping process, since it can span the entire space between the two jaws and nevertheless can be pressed together transversely due to its corrugation, while maintaining its supporting surface between the two jaws. It is also avoided in this way that the thickness of the support part requires precise machining. Precise machining is sufficient.
  • the "Thickness" parameter loses its meaning and the support part replaces a complete set of the previous support parts with the same height. This brings with it significant savings, and it is also much easier and easier to clamp.
  • the figures show a conventional vice 1 with a fixed jaw 2 and support rails 3 and a movable jaw 5 with a rotary handle 6 for moving the movable jaw 5.
  • a spring steel strip 8 ground to the exact height or cut exactly to the width, is between the two jaws 2 and 5 inserted and normally fills with its waves the space between the jaws 2 and 5 so that a bundle of sheets 9 to be machined in height can be placed on the spring steel strip 8 and then the movable jaw 5 by turning the handle 6 against the fixed jaw 2 is moved to.
  • the spring steel strip covering the intermediate space is pressed into a flatter corrugated position until the two jaws 2 and 5 grip and clamp the package of the sheets 9. This package can now be ground and milled to the exact height, for example.
  • the laminated core is very thick, two spring steel strips can also be inserted. For each desired height there is a pair of corresponding spring steel strips 8. Their contact surface is so wide that if the shafts of a spring steel strip 8 lie between the jaws 2 and 5 and touch them, sheet metal cannot fall between the jaws.
