Definitions

  • the invention relates to a clamping device, consisting of a head piece arranged on an actuating element, on which the clamping arm, which can be pivoted by the actuating element, is arranged and which is provided with at least one lateral mounting hole for the workpiece support and / or the device holder.
  • Such 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.
  • the invention is based on the object, a device of the second type, which thus has a laterally arranged clamping arm, in a simple manner in such a way that largely the same and in this respect optimal load conditions result as in devices of the first type.
  • At least one mounting recess is understood to mean that a corresponding mounting recess can also be provided on the other flank surface parallel to the flank surface, as is usually practiced on such devices in order to take into account the opposite installation arrangements of such devices and corresponding tension arm orientations can.
  • the torque load in the device according to the invention affects only between the clamping arm and the workpiece support or its cold, but not to the central longitudinal plane, which would be the case if the mounting recess would extend transversely to it as previously.
  • the clamping device consists, in a known manner, of a head piece 1 arranged on an actuating element 8, on which the clamping arm 3, which can be pivoted by the actuating element 8, and which has at least one lateral mounting recess 5 with screw holes 4 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 of which is coupled in a known manner to the tensioning arm 3 in order to be able to pivot it in the tensioning and opening position with respect to its pivot axis 11.
  • the mounting recess 5 is arranged in the flank surface 6 of the head piece 1, on the side of which the clamping arm 3 is also mounted on an actuating shaft end 7 protruding from the head piece 1 , and that the workpiece support 9 is arranged centrally to the central longitudinal plane E intersecting the clamping arm 3.
  • a mounting recess 5 ' is also provided in the side surface 6' parallel to the side surface 6, and the workpiece support 9 is seated on a device holder 2, as shown, for example.
  • the device holder 2 which can also have a different shape in adaptation to the respective installation location - the same also applies to 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 extension arm 2 ' the bracket recess 5 and is fixed there with screws in the screw holes 4.
