Definitions

  • the invention relates to a drilling or milling device with a drilling or Milling crown and preferably a centering pin and a drive machine.
  • the invention is therefore based on the object of a drilling or milling device to propose with which such openings are made with precision can.
  • This bearing ensures that the drill or milling crown is properly guided achieved, which in turn leads to an exact formation of the intended opening leads.
  • An advantageous embodiment of the invention is that for guiding the bearing a subframe is provided which is mounted for longitudinal displacement.
  • a guide column can be provided for longitudinally displaceable mounting of the subframe.
  • a guide pillar is particularly the case with constant use of the Drilling or milling device advantageous because they are made relatively rigid can.
  • a further advantageous embodiment of the invention is characterized in that the drilling shaft is rotatably and longitudinally displaceable in its bearing.
  • Drilling shaft is formed at least in two parts and its length can be changed.
  • Another advantageous embodiment of the invention is that a support frame is provided on which the guide device is mounted.
  • Such a support frame gives the entire device high stability and Independence from other components, since the facility is completely independent everywhere can be set up.
  • Support frame is provided with at least one base.
  • the base can be designed as a one-piece plate or as a strip construction.
  • a drilling or milling device with a drilling or Milling crown and preferably a centering pin and a drive machine provided that the crown is sleeve-shaped and at its cutting edge Cutting, preferably made of hard metal, has seen in the circumferential direction are directed alternately outwards and inwards.
  • the diameter of the borehole is determined with the outward-facing cutting edges, while the inward cutting edges reduce the drill core so that it is easy to remove from the crown.
  • the drill or milling crown on its outside with from the cutting outgoing grooves is provided, the grooves in front of the respective Cutting are arranged.
  • grooves increase helically according to the invention are formed and are preferably provided with an open end.
  • This configuration is based on an advantageous development of the invention achieved in that the grooves are machined into the outer surface of the crown and at the end remote from the cutting edges with a transition to the outer surface are provided.
  • the drill or milling crown is provided with an adapter on which the crown is interchangeably attached.
  • Multi-adapter adapter for crowns with different diameters is provided.
  • a further advantageous embodiment of the invention is characterized in that the subframe is equipped with an adjustment drive.
  • Adjustment drive at least one rack arranged on the guide column has, on which a rotatably mounted gear rolls, which with a Rotary device is rotatably connected.
  • FIGS. 1 and 2 denotes a drilling device which has a support frame 2 has, on which two guide rods 3 are attached. At the bottom of the The support frame 2 has two angular strips 4 serving as feet.
  • On The two guide rods is a pivot bearing 7 for a subframe 5 Drill shaft 8 mounted longitudinally.
  • the drilling shaft 8 is in the rotary bearing 7 rotatably and longitudinally displaceable.
  • At the top of the drill pipe is over a drill chuck 9 attached to a drill 10 with an angular drive.
  • This Drill 10 is attached to a sliding bearing 11, which is also on the Guide rods 3 is mounted.
  • the sliding bearing 11 is also with a Provided locking device 12 through which an unintentional sliding down Drilling machine 10, the drilling shaft 8 and one at the lower end of the drilling shaft 8 attached drill bit 13 can be prevented.
  • the lock is released, which for simultaneous lowering of the drilling unit from the drill bit, drilling shaft and drilling machine serves.
  • the drill bit is lowered when the component is inserted appropriate hole should be drilled on. It is also conceivable that Determine drive machine, and the drilling shaft in two parts and thus to be adjustable in length. About a corresponding, not shown Lever device can then be lowered the drill bit without the Drive machine must be moved.
  • the pivot bearing 7 is when lowering the drilling unit together with the Subframe 5 lowered as far as the guide rods 3 allow. At the The drill shaft is then lowered further in the longitudinal direction Pivot bearing 7 moved.
  • the drill bit 13 is provided with individual teeth, between which proportionally large recesses are provided in which chips and drilling dust get and enable trouble-free drilling.
  • the drill bit can also be provided with helical grooves on the outside, through which the cuttings are also removed when the drill bit is turned.
  • a centering pin which is a, is expediently arranged in the interior of the drill bit prevents the drill bit from running sideways.
  • Center drill used, their length according to the intended purpose is selected.
  • the device 41 has a central one Guide column 42 equipped on which a correspondingly adapted subframe 45 is slidably mounted.
  • This subframe 45 contains a pivot bearing 47 for the Drill bit 43 and a bearing 51 for the drive machine 50 is on the subframe still a handwheel 46 rotatably arranged with which the height adjustment of the Subframe and thus the drill bit is made.
  • an intermediate piece 52 is arranged, which in turn on an adapter 53 is mounted. With this adapter you can keep the same Core bit the possible drilling depth can be changed.
  • the guide column sits on a support foot 54, which is designed as a plate and one Has opening through which the drill bit 43 can reach.
  • the two lateral edges of this support foot plate are designed as slide rails, which in engage corresponding longitudinal grooves of the base frame 55, whereby the drilling device is adjustable in this direction.
  • the other design of the base frame 55 corresponds to that shown in FIG. 3.
  • FIG 5 shows a drilling device 51 which essentially corresponds to that according to FIG corresponds.
  • the drill bit 43 is, however, attached directly to the adapter 53 here.
  • On the back of the guide column 42 is a horizontal rack 56 arranged, in which an invisible gear meshes, which rotatably with the Handwheel 46 is connected. So that the subframe 45 and thus the Drilling device can be moved along the guide column using the handwheel.
  • the configuration of the drill bit 43 is shown in more detail in FIG.
  • the sleeve-shaped trained drill bit 43 has six hard metal cutting edges 61 at its cutting end or 62, which are arranged alternately in the direction of rotation one behind the other.
  • the Tungsten carbide cutting edges 61 have their cutting tip directed outwards, while the Cutting 62 are formed with the cutting tip facing inwards, so that the Wall thickness of the core bit is cut free and inside the Drill bit creates a drill core that can be easily removed from it.
  • a groove 63 begins to cut into the surface of the drill bit sleeve are incorporated and lead helically away from the cutting edges. Through this Grooves 63 become the separated material on the outside of the drill bit reliably discharged. In the end, each groove is open, i.e. it rises Outside surface so that the material removed from the respective groove is thrown out.
