Definitions

  • the invention relates to a pneumatic cylinder according to the preamble of the main claim.
  • the stroke is limited by the housing cover arranged at the ends of the cylinder tube, i.e. the piston stroke is always constant.
  • the pneumatic cylinder according to the invention has the advantage that the piston stroke can be freely selected. This significantly improves the range of applications for this pneumatic cylinder.
  • FIG. 1 shows a side view of a pneumatic cylinder, in FIG. 2 a section along II of FIG. 1.
  • 10 denotes the cylinder tube of a pneumatic cylinder, which is closed on both sides by covers 11, 12.
  • a piston 13 is slidably mounted in the cylinder tube 10, to which an extension 14 is fastened, which projects outwards through a longitudinal slot formed in the cylinder tube. Sealing to the outside takes place via a band-shaped sealing strip 15.
  • Such pneumatic cylinders are known, e.g. from DE-OS 21 62 572, and therefore not described further.
  • Two stops 17, 18, which cooperate with the extension 14, serve to adjust the stroke or limit the stroke of the piston 13.
  • the stops 17, 18 are arranged so as to be displaceable on spindles 19, 19 'which are coaxial with the cylinder tube 10.
  • the stops can be moved by hand, for example, or the spindles can be designed as threaded spindles which are driven by drive motors 20, 20 ', expediently by electric motors or any stepping motors.
  • the stops then have a corresponding internal thread. If the stroke should only be adjusted in one direction, then of course only one spindle with a stop and a motor is required.
  • a toothed belt or a steel belt for a fixed resolver on the extension 14 or to provide sensors for a fixed coded scale or a coded steel belt with fixed sensors.
  • any damping device 21, 22 on the stops can consist of a rubber buffer.
  • the stops can of course also be adjusted and clamped by hand.
  • the pneumatic cylinder can, but need not, be equipped with an outwardly projecting piston rod 22. Usually, however, the force of such a cylinder is tapped at the extension 14.
