Definitions

  • This invention relates to a tensioning element and a tensioning system for positionally flexible clamping of workpieces according to the The preamble of claim 1 or 15. From the document DE 33 29 942 C, such a clamping element or clamping system is known.
  • the clamping can be done at two opposite points, as well as at Three- or four-point voltage radiating in the same angular position each other be assigned.
  • there is a universal applicability to the a variety of workpieces is designed, as well as the property of the workpieces both outside and inside to be able to stretch.
  • An important feature is the Maintaining the clamping and holding force regardless of the processing force, or even in cases of pressure drop.
  • the slide 7 are assigned to each piston 4 and are in a guide groove 3 in the housing. 1 guided smoothly.
  • Each slider 7 is associated with a clamping jaws 8, by means of Screwed on the slide stuck. These jaws are interchangeable and adaptable to the circumstances.
  • the two outer pressure chambers 5 are connected to a pressure channel 13.
  • Fig. 4 shows an embodiment with two individual elements that work together on a workpiece. These Individual elements can be controlled individually or jointly. For this Either separate hydraulic lines are necessary or a line with appropriate connection between the elements. In both cases it is required to operate the approach to the workpiece controlled.
  • the wedge element (a Keilstein 17) can be provided in these cases with only one wedge surface 18 and it is designed as a rocker at the same time as a driver in the slide effective.
  • the slider 19 is formed here as a wave, as well as he can with a Rectangular cross-section be provided.
  • wedge surfaces 38 find their Counterparts in the wedge slopes 39, which are associated with the transport nuts 33.
  • the clamping nose 32 a is designed to be pivotable, so that their clamping jaw part 37 to 90 ° is pivotable.
  • the clamping stroke is kept relatively large and is made by the workpiece usually only partly used.
  • length-specific fittings 40 is made the distance between two round heads 32,32a changeable. This up the respective workpiece-related fitting 40 is unilaterally with the round head 35th firmly connected.
  • the evenly building up clamping force causes over the Wedge surfaces and wedge slopes also a uniform jamming of the Transport nuts and the clamping lugs in their guides and the same Clamping and holding forces on the workpiece.
  • the clamping lugs 32,32a are moved and depending on the spindle rotation on each other or moved away from each other.
  • the Workpiece 15 is inserted between the round head 35 and fitting 40 and through the Spindle movement fixed. Over the wedge surfaces 38 and wedge slopes 39 The round heads jam against the transport nuts and set the system firmly.
