Definitions

  • the invention relates to a pressure spindle for a Puller, with an external thread for screwing in an internal thread of the puller, with one end of the Pressure spindle is a pressure piece in the form of a centering tip carries and the other end of the pressure spindle one Rotary attack section in particular in the form of a tool attack profile formed.
  • the invention further relates to a puller with a such pressure spindle.
  • Such pullers are for example from the Known from DE 199 092 74 A1 or DE 198 445 08 A1. With regard to the basic design of generic printing spindles or generic pullers, reference is made to the total content of the two publications.
  • the invention has for its object a generic Puller or a generic pressure spindle Advantageously further training for a puller.
  • Claim 1 initially and essentially provides that the pressure piece is interchangeably assigned to the pressure spindle is. Now the pressure piece can be used without a Unscrew the pressure spindle from the internal thread is required to be changed.
  • the pressure piece is reversible with two different designed centering points in one to the front of the Pressure spindle end of open cavity is stuck.
  • the exchange the centering tip can then be turned over simply of the pressure piece.
  • the pressure piece can a cone tip on one side and a ball on the other side exhibit.
  • the pressure piece can have a cylindrical, in particular have a circular-cylindrical holding section, with which it is held in the cavity.
  • the attitude is preferably frictional.
  • the Holding section approximately in the axial center of the pressure piece have an annular groove in which an O-ring lies. This elastic O-ring works with the wall of the designed as a circular cylindrical bore together so that the pressure piece does not fall out of there can.
  • the pressure piece is supported when using the Puller with its protruding into the cavity Center point at the bottom of the cavity.
  • the Bottom of the cavity one corresponding to the tip of the cone Have a negative shape, so that the conical centering tip there in the area.
  • the end face assigned to the rotary attack section an open cavity.
  • the size of this cavity corresponds to the cavity of the other spindle side, see above that in this, assigned to the rotary attack section Hollow a replacement pressure piece can be inserted can, which against that in the opposite cavity inserting thrust piece can be replaced.
  • This Replacement pressure piece can be used instead of a pressure tip have a pressure plate so that it is suitable is objects such as bearings or the like of hollow shafts deducted.
  • the advantage is the captive assignment the replacement pressure piece to the pressure spindle or to the puller.
  • a puller 1 is shown, which a crossbeam 2 forms in the middle has an internal thread, not shown, in which screwed the pressure spindle 3 with its external thread is.
  • a pull hook 5 arranged at their hook ends 4 facing inwards or by turning the pull hooks 5 Form hook projections facing outwards.
  • the pressure spindle 3 has a pressure piece on one end 6 with a centering tip and one on the other side Revolving handle section 7, which is in the form of a hexagon section has an open-ended wrench can to rotate the pressure spindle 3.
  • the design of the pressure spindle 3 according to the invention illustrate the figures 2 to 8.
  • the pressure spindle 3rd possesses on their mutually facing end faces each a cavity 13, 14.
  • the cavity 14 is the Assigned rotary attack section 7.
  • In the cave 14 inserts an exchange pressure piece 6 '.
  • a pressure piece 6 a In the opposite cavity 13 is reversible a pressure piece 6 a.
  • This pressure piece 6 has essentially the shape of a cylinder with a circular cross-section.
  • the one Centering tip 8 is designed as a ball. It can in this case in a recess of the pressure piece 6 set ball 8 act.
  • the opposite center point 9 is designed as a cone. The cone owns a peak.
  • the pressure piece 6 Approximately in the middle between the two centering tips 8.9, the pressure piece 6 has a holding section 12.
  • the hollow 14 opposite the hollow 13 is designed the same, so that the pressure piece 6 there too can come into friction with the O-ring 11.
  • the holding section 12' is identical to the holding section 12 is made. Also there is an annular groove 10 'in which a O-ring 11 'lies, so that this holding section 12 'frictionally on the wall of the bore 14 is applied.
  • This pressure piece 6 ' carries a pressure plate on one side 15, the use of the puller to use hollow shafts Can be found.
  • the other end of the pressure piece 6 ' has a conical shape.
  • the pressure pieces 6,6 'in each of the two cavities 13,14 be plugged in.
  • the pressure piece 6 can even be turned over be inserted into one of the two cavities, so that use a total of three or four pressure peak profiles can find.
  • the diameter of the pressure plate 15 is preferably is smaller than the diameter of the rotary handle section 7, can on the hexagonal rotary handle section 7 also a nut or a ring spanner be put on.
  • the captive assignment of the interchangeable is essential Pressure tip profiles for the pressure spindle.
