Definitions

  • the present invention relates to a centering and drilling device with retractable barrel.
  • This device is characterized by the fact that the piercing barrel can be brought under the drill bit to center, and then moved backward to pierce, by simple pressure of the piercing lever against a stop provided with a switch.
  • This device is fixed to the drill column by means of a two-part collar locked by four screws.
  • One of these two parts of the collar is surmounted by a sole in which an entry of "T" is machined on its length.
  • a slide is fixed on this sole by two screws taken in the entry of "T”.
  • the slide is surmounted by a cylinder.
  • the axis of the piston of this cylinder is threaded at one of its ends.
  • a stud is screwed to which a tongue is fixed by two screws.
  • this tab is housed the drilling barrel, it can be raised or lowered, along the length of the drill bit, by the slide which is fixed by two screws on the sole.
  • the collar 1 in two parts, is fixed to the collar of the drill by the four fixing screws 13.
  • One of the two parts is provided with a sole 2 in the. which is milled an entry of "T" over its entire length.
  • a slide 3 is fixed by the two screws 12 on the sole 2, allowing the height to be adjusted according to the length of the wicks.
  • the slide 3 is surmounted by a cylinder 4.
  • the axis of the piston 5 has its threaded end on which a stud 9 is screwed for adjusting the centering.
  • the tongue 7 is fixed to the stud 9 by the two screws 17. At the end of the tongue is housed the drilling barrel 8.
  • the stud 9 is guided by a bar 6 which slides in a bearing 10, which prevents it to turn.
  • the air enters the cylinder 4 through the orifices 11.
  • the piston is guided in the cylinder by ball guide 18 at the two ends, which gives a rigid and precise movement.
  • the ring 14 which is fixed to the spindle abuts a pusher 15.
  • This pusher 15 transmits a pressure to a switch 16, which sends an electric current to a solenoid valve, that -this sends compressed air into the cylinder 4 which advances the piston and the barrel 8 for centering.
  • the spindle is mounted by the drilling lever.
  • the switch 16 is again open.
  • the solenoid valve sends compressed air opposite the cylinder 4 and causes the piston as well as the barrel 8 to move back, the drill bit is free and drilling can be carried out freely without the barrel.
  • the advantage of this device is that one can pierce parts correctly, without difficulty and without jamming in the barrel.
