Definitions

  • the invention relates to a multi-part pin puller for withdrawing a pin or bolt from a hole of a component, comprising a threaded tie rod and a tie rod receiving holder, which is supported for releasing the pin from the component to the latter, wherein the pull rod with the to be solved pin connectable and connected in the state connected to the pin by rotating a screw supporting itself on the holder in the drawing direction.
  • Multi-part pin pullers for pulling out a pin or bolt from a hole of a component are well known, such as from DE 18 53 600 U and DE 20 2006 014 177 U1 , The latter includes the preamble of claim 1.
  • the pins are usually fixed in the component and are generally held by frictional engagement.
  • the pin is often sunk flush in the component.
  • the pin puller comprises a pull rod which can be screwed to the withdrawing pin and which can be supported on the holder and can be moved under the action of a force along its axial direction to pull the pin out of the component.
  • the holder of the pin puller is supported on the component, which thus forms the abutment for the force acting on the pull rod force.
  • pin to be pulled can be screwed to the pull rod, due to a non-axis-parallel arrangement of pin and pull rod and the threaded portions of one of the two components wear, so that if necessary, a pin to be solved is no longer removable from the component.
  • the object of the invention is therefore to provide a multi-part pen puller to be safely avoided by the damage to the component from which the pin or bolt to be pulled out.
  • the invention is based on the finding that when the holder has means for aligning the pin puller relative to the component, both wear on the parts of the pin and pull rod involved in the form-fitting and tilting of the pull rod relative to the axial direction of the pin can be reliably avoided , Due to the provided means, the pull rod is always moved concentrically to the axial axis of the pin or bolt along the pulling direction, so that wear on the component can be avoided by tilting. Likewise, the wear on the form-fitting components of the pin and the pin puller can be safely avoided because due to the predetermined fixed orientation and positioning of the pin puller relative to the pin at any time the positive locking can come about properly.
  • the holder has a hook-shaped projection as a means for aligning the pin puller.
  • the hook-shaped projection is matched to the groove depth, so that along this direction a displacement of the pin puller during the release of the pin can be safely avoided.
  • the hook-shaped projection in a groove provided on the component is almost free of play, so fit to use.
  • the wall thickness of the hook-shaped projection and the width of the groove are therefore coordinated.
  • the projection provided on the holder extends transversely to the pulling direction. This makes it possible that the holder does not move relative to the component during extraction of the pin.
  • the approach to an opening for receiving the pin results in a two-part approach to the holder, between which the pin can extend therethrough, provided that the groove extends transversely to the axial direction of the pin.
  • the pull rod has a thread which can be screwed to the pin. This allows a particularly secure and sufficiently reliable positive connection between pin and pin puller to pull the pin out of the hole.
  • FIG. 1 shows in an exploded view of a multi-part pin puller 10 according to the invention for pulling out a pin or bolt from a hole of a component.
  • the component may be, for example, a rotor disk of a gas turbine, as disclosed in the European patent application with the official registration file 07 000 381.9 is known.
  • the in the European patent application with the official registration file 07 000 381.9 disclosed subject matter explicitly incorporated into this patent application and thus part of the disclosure of this patent application.
  • the pin puller 10 comprises a holder 16, in the opening 14 of a pull rod 12 can be used.
  • the pull rod 12 is provided with at least a first threaded portion 18, on which a nut 20 can be screwed.
  • the holder 16 comprises, in addition to the opening 14, a contact surface 22 which can be applied to the area surrounding the hole from which the pin is to be pulled out. Furthermore, the holder 16 as a means for aligning the pin puller 10 relative to the component comprises a hook-shaped Approach 24, in which a further opening 26 is provided. The free end of the hook-shaped projection 24 extends transversely to the pulling direction Z of the tie rod 12.
  • the pull rod 12 includes a second portion 19, which is provided for producing a positive connection with the pin.
  • the portion 19 has a second external thread which can be screwed with a concentric internal thread provided on the pin.
  • FIG. 2 shows the multi-part pen puller 10 in the assembled state and in the screwed state with a pin 32 in cross-section.
  • the pin 32 is sunk in a component 30, for example in the rotor disk known from the aforementioned European patent applications and serves to secure a sealing element against displacement in the circumferential direction.
  • the pin 32 is seated in a hole 34 which extends through a provided in the component 30 on one side open groove 36.
  • an internal thread 40 is provided, which can be 29braubbar with the provided on the second portion 19 of the drawbar 12 thread.
  • the hook-shaped projection 24 of the holder 16 is used approximately without play in the groove 36, wherein the opening provided in the projection 24 26 engages around the pin 32 laterally.
  • the selected width of the opening 26 corresponds to the outer diameter of the pin 32. Due to the predetermined length of the two legs flanking the opening 26 of the projection 24, it is possible to position the axis of rotation of the tie rod 12 parallel to the axis and congruent to the axis of symmetry of the thread 40 of the pin 32.
  • the tie rod 12 in the pin 34 in a particularly simple manner be screwed. After reaching a required screwing the tie rod 12 can now be moved by means of the nut 20 by turning the nut 20 against the pull rod 12 in the pulling direction, the nut 20 is supported on the bracket 16 and the bracket 12 on the component 30. In order to prevent co-rotation of the pull rod 12 when turning the nut 20, this can be fixed by means of a wrench to be attached to the head 44 of the tie rod 12.
