Definitions

  • the present invention refers to a procedure for mounting elongated, principally cylindrical elements such as expander pins in predrilled holes, for example.
  • Expander pins are resilient locking pins used for the demountable assembly of various machine elements or mechanical components, e.g. for mounting wheels and the like on shafts.
  • the expanding capability is usually achieved by designing the expander pin as a slotted, springy sleeve of alloy steel which is made resilient by heat treatment.
  • Expander pins are mounted in holes having a diameter less than that of the pin, with the result that the pin is compressed when driven into the hole. Since the pin endeavours to spring back to its normal expanding state it exerts sufficient pressure against the inner surface of the hole to prevent axial movement.
  • FIG. 1 shows a longitudinal cross-section through a tool according to the invention.
  • the tool consists of a sleeve 1 which is provided with an axial through hole 2.
  • a striker 3 is so arranged in the hole 2 that it can move in an axial direction.
  • the end of striker 3 outside the sleeve 1 is designed as an impact head 4.
  • the cylindrical element which in the version shown consists of an expander pin 5 is arranged to be accommodated in the hole 2 at the opposite end of the sleeve 1 to the aforementioned impact head 4.
  • a chiefly radial hole 6 is provided in the sleeve 1 close to the end accommodating expander pin 5.
  • a loosely fitted locking pin 7 which rests against the expander pin.
  • This locking pin is retained and pressed resiliently against the expander pin 5 by a rubber ring 8.
  • the rubber ring 8 is fitted in an annular groove 9 in the surface of sleeve 1 adjacent to the radial hole 6. The resilience of rubber ring 8 is adapted so that expander pin 5 is retained by the friction, even when the tool is pointed downward, but not so that mounting of the pin is noticeably obstructed.
  • a corresponding locking device can be utilized to retain the striker 3 in sleeve 1.
  • a return spring (not shown) can be arranged between the striker and the sleeve to return the striker to the position of rest after each blow. Further, the aforementioned striker can be provided with a means of restricting its outward movement.
  • the spring force applied to expander pin 5 from the side can naturally be arranged in many ways and the version described above is only an example.
  • the tool can also be designed for easy connection to the pneumatic impact tool.
  • the pin 5 When using the tool described above for mounting an expander pin 5 in a predrilled hole, the pin 5 is first fitted in the hole 2 in the sleeve 1. Locking pin 7 is pressed against expander pin 5 by means of rubber ring 8. The sleeve 1 is then applied to the predrilled hole and expander pin 5 is located in its mouth. Impact head 4 is subjected to repeated blows with the effect that the striker 3 strikes expander pin 5 and drives it into the hole.
