Definitions

  • the invention relates to a device for grinding the cutting of drill bits consisting of a displaceable and / or rotatable base plate and a base part fastened thereon with a clamping device for the drill bit to be ground in the form of two clamping jaws connected as a unit, which on a receiving part on the base part are arranged reversible, and a grinding unit carrying a grinding wheel.
  • Such a device which corresponds to the preamble of claim 1, 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 as Unit connected to use the twist drill.
  • 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 during regrinding on the front or circumferential side of the grinding wheel.
  • lateral angular groove guides are arranged on the receiving part, and in that the clamping jaws on the four outer edges on the plug-in end angular groove guides cooperate when repositioning, with a pressure screw on the receiving part of the releasable jamming of the Clamping jaw unit serves.
  • the receiving part on the stand part can also 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.
  • the two jaws of the 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 in FIG. 2.
  • the clamping jaw unit 4 is received here by means of the four angular incisions 10 on the outer edges of the prisms 6, 7 on the receiving part 5 and specifically its lateral angular groove guide 11, 12 in the guide part 13 by being pushed in the direction D by means of a pressure screw 14 releasably clamped during insertion, as shown in FIG. 1.
  • the receiving part 5 can be pivoted and locked 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 Ai-Ai in the direction of rotation F.
  • 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 and has a clamping screw 21 as a fine adjustment, as shown in FIG. 4.
  • the receiving part 15 with the back part 16 is adjustable 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 A i -A i in the direction of rotation F
  • a further pivoting about an axis running perpendicular thereto is also possible BB is provided in the direction G of the guide part 13, the drill axis CC and the horizontal axis AA each crossing in space.
  • the guide part 13 pivotably arranged to the back part 16 consists of two parts, namely this (13) consists of the angular groove guide with rotating eye 13a and the receiving shoulder 13b and the clamping 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.
