Definitions

  • the invention relates to a device for displaying the position of a hydraulic cylinder, in particular as an actuator of a roll adjustment with a piston movable in a cylinder, the surface of which presses directly against the bearing pieces of the rolling mill.
  • the attachment to the cylinder head is also unfavorable, because the position sensor there is strong environmental pollution, i. H. Water vapor, dripping oil and mechanical stress is exposed.
  • the object of the invention is to provide a device of the type mentioned at the outset which enables a highly accurate and reproducible displacement measurement of the piston.
  • the main idea of this embodiment is that the thin tube which is passed through the cylinder base and which is connected to the piston on the other hand absorbs the forces at the sealing point in the cylinder base as well as the frictional forces in this area while the actual measuring rod, which is freely movable within this thin tube, can precisely transmit the movement of the piston without hindrance by external forces.
  • the actual measuring rod 4, which is connected to a measuring device 5, is arranged within the tube 3 and also connected to the piston 2. In this way, the movement of the piston 2 is transmitted directly to the measuring device without longitudinal and transverse forces acting on the measuring rod, so that the highest accuracy can be achieved.
