Definitions

  • the invention relates to a cylinder according to the preamble of the main claim.
  • a known working cylinder has the disadvantage that it cannot be used optimally because its function is very limited.
  • the working cylinder according to the invention with the characterizing features of the main claim has the advantage that it is versatile, in particular that the piston rod can be precisely positioned and locked and that the piston rod is not rotated by braking the piston rod by an eccentric.
  • FIG. 1 shows a side view of a working cylinder, partly in section
  • FIG. 2 shows a top view of the working cylinder
  • FIG. 3 shows a section along III-III according to FIG. 2.
  • 10 denotes a cylinder tube which is closed on both sides by covers 11, 12 and via which the cylinder tube is clamped to the covers with the aid of four clamping screws 13.
  • an opening 14, 15 is formed for the supply or discharge of the pressure medium for actuating the piston or the piston rod.
  • two through bores 16, 17 are formed in the cover 12, in which rods 18, 16 are slidably guided, which are connected at their end facing away from the cover 11 by a yoke 19.
  • the rod 18 is coded, e.g. B. in that at certain intervals rings 20 made of a material with magnetic Properties are inserted that differ significantly from the magnetic properties of the material of the rod 18.
  • thread-like grooves can also be provided, which are filled with a similar material, or a band of magnetized material can also be inserted into the rod 18.
  • the piston rod is designated 25.
  • An eccentric ring 26 is slidably rotatably mounted on it, which is also mounted in a bore 27 of the cover.
  • the eccentric 26 has an upstanding bolt which engages in a slot 29 of a piston 30 which is slidably guided in a bore 31 of the braking device.
  • the piston 30 is acted upon by a valve 32 through a bore 32 and a line, not shown, with pressure medium. Contrary to the pressure medium pressure force acts on the piston 30 a compression spring 34 which is supported on a spring abutment 35 which is housed in a side part 36 of the braking device.
  • Such a braking device is known from DE-OS 25 15 566.2.
  • the compression spring 34 brings the piston 30 into such a position that the bolt 28 rotates the eccentric 26 so that it clamps the piston rod 25.
  • the electronics control the valve 23 in such a way that pressure medium flows through the bore 32 into the bore 31.
  • the piston 30 moves to the left, the bolt 28 is pivoted counterclockwise in such a way that the eccentric ring 26 releases the piston rod.
  • the piston and piston rod now move. If this has reached a certain position, which is characterized by the coding on the rod 18, the electronics 22 give a signal to the valve 23, which now immediately stops the pressure medium flow to the bore 32. Now the compression spring 34 brings the braking device back into the braking position, the piston rod is immediately tightened.
  • the piston rod can be moved to any position and clamped there by means of appropriate coding and control via the electronics.
  • a compensating coupling 39 is provided between the yoke 19 and the piston rod 25.
  • This consists essentially of a cylindrical body 40 which is screwed onto the piston rod 25 by means of a screw bolt 41 and a nut 42 arranged at its end.
  • the cylindrical body 40 has a transverse slot 45, into which a disk 43 is inserted with a bolt 44 which extends toward the yoke and which is screwed to the yoke by means of a screw 46 arranged therein.
  • the cylindrical body 40 is thus firmly connected on the one hand to the piston rod 25, and on the other hand via the disk 43 and the bolt 44 with little axial and radial play with the yoke 19.
