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 since the parts to be machined can fall down between the platelets and the movable jaw, for example a vice or 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 be the same as those for the insertion. necessary distance of the clamping jaws from one another have a corresponding width. A large number of differently wide support parts (depending on the thickness of the workpiece bundle to be clamped) is therefore necessary.
  • the support part is a corrugated, spring-elastic band, the underside of which is formed by a corrugated side edge which runs 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 support 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 parameter "thickness" loses all 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 more effortless to clamp.
  • 1 is a plan view of a vice with open jaws
  • FIG. 3 shows a side view of the vice 'according to FIG. 1, with movable parts lifted away and an inserted clamping element as well as the bundle of parts according to FIG. 2,
  • FIG. 4 shows a side view of the clamped parts in the vice according to FIG. 1,
  • FIG. 5 is a plan view of the vice according to FIG. 4.
  • 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 displacing the movable jaw 5.
  • a spring steel strip 8 ground to the exact height or cut exactly to the width, is between the inserted both jaws 2 and 5 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 is moved by turning the handle 6 against the fixed jaw 2.
  • 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 when the waves of a spring steel strip 8 lie between the jaws 2 and 5 and touch them, there is a fall between the jaws of sheets is impossible.
