Definitions

  • the present invention relates to a centering and drilling device with retractable barrel for drill.
  • Document US-A-2 817 253 describes such a device fixed to the column of the drill and the barrel of which can be placed under the drill bit for pointing and removed, manually, by rotation about a vertical axis to allow drilling. The entire device can be adjusted in height on the drill column.
  • the advantage of the device which is the subject of the invention over the prior devices consists in that it makes it possible, on the one hand, to carry out the positioning of the barrel under the drill bit for pointing and on the other hand withdrawal of the barrel to allow drilling.
  • This device is characterized by the fact that the positioning and removal of the barrel is carried out automatically by means of a jack supporting the barrel and controlled by a control device itself actuated by the lever. drilling hole.
  • 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 which an entry of "T" is milled 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 is screwed a stud 9 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 causes the piston and the barrel 8 to advance.
  • the spindle is mounted by the drilling lever.
  • the ring 14, which is fixed to the spindle again stops the pusher 1 5.
  • 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.
