Definitions

  • the invention relates to a device for grinding the cutting of drills consisting of a displaceable and / or rotatable base plate and a base part fastened thereon with a clamping device for the drill to be ground in the form of two clamping jaws connected as a unit, which are attached to a receiving part on the base part are arranged reversible, and a grinding unit carrying a grinding wheel.
  • 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 arranged on a horizontal pivot of a standing part in front of the grinding unit so that it can be moved and pivoted.
  • the reclamping device is to be held by hand on its swivel bearing when regrinding on the front or circumferential side of the grinding wheel.
  • the receiving part on the stand part can additionally be rotatable and lockable about an axis running perpendicular to this, the drill axis and the horizontal axis crossing each other in space.
  • this makes it easy to detach and change, and the combined horizontal and vertical swivel axis adjustment makes it easy to adjust the drill bit for the grinding process.
  • the receiving part on the back part which can be adjusted and locked, can itself be pivoted and locked around a parallel axis, the guide part for the reversible clamping jaw unit then being rotatable about the perpendicular axis, thereby additionally allowing the side part to be pivoted without rotating the base part is achieved.
  • the device is used to grind the cutting edges of drills in conjunction with a grinding unit 1 with a 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 a receiving part 5.
  • the clamping jaw unit 4 consists of two prisms 6 and 7 with angular grooves 6a, 7a and encompassing U-guide piece 8, the one prism 6 being screwed tight at 8a and the second prism 7 being guided displaceably by means of a keyway 8b by a clamping screw 9.
  • the prisms 6 and 7 have angular rail incisions 10 on all four outer edges on the push-on end for implementation during drill grinding on the one hand and on the other hand. Furthermore, the two clamping jaws of the clamping jaw unit 4 have an extendable and lockable end piece 6b or 7b on each prism for extending the holding for long drills 3, as can be seen from FIG. 2.
  • the clamping jaw unit 4 is here by means of the four angular incisions 10 on the outer edges of the prisms 6, 7 on the receiving part 5, namely its lateral angular groove guide 11, 12 in the guide part 13, so that it can be plugged in by pushing in the direction D to be releasably clamped by means of pressure screw 14 after insertion, such as this shows Fig. 1.
  • the receiving part 5 is on the stand part 15 both about the horizontal axis A-A in the direction of rotation E and on the back part 16 about the parallel axis A1-A1 in the direction of rotation F pivotable and lockable.
  • the adjustment of the back part 16 on the stand part 15 by means of bolt-hole connection 17, 18 is to be determined in stages, as shown in FIG. 3.
  • the additional pivoting of the guide part 13 takes place via an eccentric head 20 which can be rotated in an oval hole 19 with a clamping screw 21 as a fine adjustment, as shown in FIG. 4.
  • the receiving part 15 with the back part 16 about the horizontal axis AA in the direction of rotation E and with its guide part 13 on the back part 16 about a parallel axis A1-A1 in the direction of rotation F is adjustable for this purpose
  • a further pivoting about a perpendicular axis BB in Direction G of the guide part 13 is provided, the drill axis CC and the horizontal axis AA each crossing in space.
  • the guide part 13, which is arranged pivotably with respect to the back part 16, consists of two parts, namely it exists (13) from the angular groove guide with rotating eye 13a and the receiving shoulder 13b as well as the tensioning lever 22 provided for fixing the joint.
  • the stand part 15 can in turn be adjusted by means of a rotating plate 23 with a locking lever 24 for rotating H on a slide 25 at right angles to the grinding unit 1, that is to say in the direction J against the peripheral surface of the grinding wheel 2, the grinding unit 1 being displaceable transversely thereto in the direction K for further adjustment is.
  • Both the rotary plate 23 and the infeed for the slide 25 can be provided with setting scales 23a and 25a, as shown in FIG. 1.
