Definitions

  • the invention relates to a device for grinding the cutting of drills in connection with a grinding wheel drive consisting of a clamping device for the drill to be ground in the form of two clamping jaws connected as a unit for intermediate clamping of the same, which clamping jaws are arranged on a bolt on the stand part.
  • Such a holding device for twist drills is known, for example, from DE-PS 29 15 601 and DE-PS 31 46 664.
  • a clamping device for the drill in the form of two clamping jaws, here prisms, which are connected as a unit for Clamping the twist drill use.
  • This prism unit is then implemented on a horizontal pivot of a standing part in front of the grinding drive - and is pivotably arranged.
  • the prism unit is to be held by hand on its swivel bearing when regrinding on the face of the grinding wheel.
  • the clamping jaw unit can firmly attach itself to the back part of the L-shaped receptacle when it is attached to the bolt due to a weak oblique cut (cone back); the base part is screwed on the back of the cone and can be adjusted using a pressure screw to adjust the seat tension (cone back).
  • the device is used for grinding the cutting edges of drills in conjunction with a grinding wheel drive 1 with grinding wheel 2.
  • a clamping device for the drill 3 in the form of a reversible clamping jaw unit 4 in the manner of DE-PS 29 15 601 or DE-PS 31 46 664 provided for an L-shaped receiving part 5.
  • the clamping jaw unit 4 here consists of two prisms 6 and 7 with angular grooves 6a, 7a and encompassing U-guide piece 8, the one prism 6 being screwed tightly at 8a and the second prism 7 being guided displaceably by means of the groove 8b by the clamping screw 9.
  • the pirsmen 6 and 7 also have plug holes 10 on the one hand and on the other hand for implementation during drill grinding.
  • the clamping jaw unit 4 can be placed on the plug pin 11 of the receiving part 5, namely the base part 12 of the receptacle 5 carries the upstanding bolt 11, while the back part of the receptacle consists of two parts a cone back 13 and the back plate 14 is formed.
  • the back plate 14 is pivotally mounted on a stand part 15, specifically with a horizontal bearing pin 16 perpendicular to the plug pin 11, in such a way that when the drill 3 is clamped, the cutting head 3a of the bearing axis AA, crossed by the bearing axis AA, is held pivotably in the direction B.
  • the base part 12 is arranged at right angles on the cone back 13, which (13) is in turn offset on the back plate 14 to the axis A-A at 16a between limits.
  • the cone back 13 has a weak inclined cut C, so that when the clamping unit 4 is plugged onto the bolt 11, the same (FIG. 4) fits tightly in the receiving part 5.
  • the base part 12 is counter-screwed at the bottom of the cone back 13 at 17 and can be adjusted slightly in the clamping angle by means of pressure screws 17a for adjusting the cone seat (seat tension).
  • the cone back 13 can also be determined to a limited extent in its additional pivoting movement D below its pivot bearing 16a by means of a slot slot guide 18, 19 in the back plate 14.
  • the bolt 18 can be screwed into the cone back 13 and engages with its screw head in the slot slot guide 19, on the back plate 14 with an underlaid ring 20 with an angular ring, on the one hand in the slot guide 19 a return spring 21 and on the other hand an adjusting screw 22 for displacement.
  • the stand part 15 is in turn by means of a rotating plate 23 and locking lever 24 for rotating E on a carriage 25 at right angles to the grinding wheel drive 1, i.e. in the F direction on the front side of the grinding wheel 2, the grinding wheel drive being displaceable transversely to the G direction for further adjustment, as can be seen in detail from the drawing.
  • Both the rotary plate 23 and the feed screw 26 for the slide 25 are provided with setting scales 23a and 25a.
  • the grinding wheel drive 1 with base 27 is in this case connected to the pin 28 in the recess 29 of the base 30 by the slide 28 with the same as this. 1 and 2 can be seen.
