Definitions

  • the invention relates to a clamping device according to the preamble of the claim.
  • Clamping devices are known, for example, from DE-A-25 55 207.
  • the holder recesses on the head piece are provided in the same way as in the other device type, that is, the holding of such devices with a laterally arranged clamping arm takes place transversely to the latter Direction of extension, and there is an offset between the clamping arm or the pressure piece arranged thereon and the workpiece support, or, conversely, the device is thereby subjected to a torque load acting transversely to the clamping arm, which is not the case with the other type.
  • a clamping device according to the preamble of the claim is e.g. known from EP-A-0 503 193.
  • the invention is based on the object, a device of second type, which therefore has a clamping arm arranged on the side, to redesign in a simple way that largely the same and in this respect optimal load conditions result, as in devices of the first type.
  • This task is according to the invention by a tensioning device according to the Claim resolved.
  • At least one mounting recess is to be understood here that also on the other flank surface parallel to the flank surface a corresponding mounting recess can be provided can, as is usually practiced on such devices to opposite installation arrangements of such devices and corresponding clamping arm orientations to be able to wear.
  • the torque load affects the invention Device only between the clamping arm and the workpiece support or their cold from, but not to the central longitudinal plane, which the The case would be if the bracket recess is transverse to it as before would extend.
  • the clamping device consists in a known manner from one to one Actuating element 8 arranged head piece 1, on which, from the actuating element 8 pivoted, the tension arm 3 arranged and that with at least one lateral, 4 screw holes Bracket recess 5 for the workpiece support 9 and / or the device holder 2 is provided.
  • a pneumatic cylinder serves as the actuating element 8, the push rod in a known manner with the Clamping arm 3 is coupled about its pivot axis 11 to be able to swivel in the clamping and opening position.
  • the device holder 2 which is adapted to the respective installation site can also have a different shape - the same applies also for the pressure piece 10 on the clamping arm 3 and the workpiece support 9 in adaptation to the shape of the workpiece to be held -, fits with its boom 2 'in the bracket recess 5 and is there fixed with screws in the screw holes 4.
