Definitions

  • the invention relates to a holding device for drills for grinding the cutting edges consisting of a base plate which carries a stand piece with a right - angled axis bolt at the upper end for attaching a clamping device for the drill to be ground.
  • Such devices for grinding the cutting of twist drills according to DE-PS 28 33 420 consisting of a base plate on which a slide is guided horizontally displaceably by means of a threaded spindle, which carries a stand which is opposite the slide about a vertical axis is pivotable and carries at its upper end a horizontal axis on which a clamping device for the drill bit to be ground is pivotally mounted, a vertical threaded bore being arranged in the slide, in which a tensioning screw penetrating an elongated hole in a base plate of the stand designed as an angle piece is screwed in is that serves to fix the position of the stand and that an upwardly projecting leg of the L-shaped base plate can have a clamping eye for receiving the bearing neck of a hand drill.
  • the clamping device is further developed so that it is formed by two intermeshing teeth with their teeth, which can be moved against each other by means of a clamping screw, and that at the end of each clamping jaw adjacent to the stand an approximately wedge-shaped approach that tapers against the tip of the drill to be clamped and a hole is provided through which the clamping jaw on the stand can be put onto the horizontal axle bolt, whereby the approach of the clamping jaws has prismatic surfaces and the clamping jaws of the clamping device by means of transverse guide pins on a side Retaining bar slidable to each other and-the clamping screw is screwed in the retaining bar.
  • the object of the present invention is to provide a simpler and cheaper design for grinding drills (twist drills), especially for do-it-yourselfers, which also result in perfect accuracy.
  • the device is characterized in that the holding piece extends as a U-shaped guide piece encompassing the prisms in both-sided U-grooves thereof, the one outer prism screwed into position with the ends of the legs and the inner prism can be displaced by means of a pressure screw for clamping the drill and the drill can be received in two opposite, angular longitudinal grooves between the prisms.
  • the prisms preferably have different longitudinal grooves on both sides in the form of angular incisions for receiving different drill diameters.
  • a home improvement machine 1 is equipped with a grinding wheel 2 and fastened to the table 4 by means of a holder 3.
  • the clamping device 5 according to the invention is arranged, the base plate 6 of which is also to be held on the table 4 by means of a tensioner 7.
  • the stand piece 8 is rotated perpendicularly thereto by means of screw axis 9; heights arranged adjustable and lockable and is used with a right-angled axis pin 10 for attaching the clamping device 5.
  • This clamping device for the drill 11 to be ground consists of the U-shaped guide piece 12, at the leg ends 13 of which a transverse prism 14 with U-grooves 15 on both sides can be inserted and fixed by screw H16 and a second transverse inner prism 17 with U-grooves 18 on both sides inside the U-shaped guide piece 12 to the first prism can be adjusted at a distance a.
  • a pressure screw 19 on the cross leg of the guide piece 12 is used when the drill 11 is inserted between the prisms 14 and 17 for its clamping in the angular longitudinal grooves 20 and 21.
  • These longitudinal grooves 20 and 21 are of different sizes and can therefore be used for different drill diameters by repositioning.
  • the blind holes 22, 23 on the side surfaces 24, 25 of the prisms 14 and 17 serve to reposition the clamping device 5 in connection with the axle bolts 10.
  • the end faces 24, 25 are arranged here at right angles to the longitudinal groove axis 20 on the prisms 14 and 17, the Feed screw 26 serves as a depth-adjustable stop of the reversible prisms 14 and 17. This allows the drill 11 to be adjusted by rotating A of the stand piece 8 to the surface F or the circumference / the grinding wheel 2 and, on the one hand, by pivoting B the clamping device 5 in the tip area and after repositioning by means of blind holes 22, 23 on the axle bolt 10.
  • a grinding stand 31 with a grinding wheel 32 and adjusting foot 33 on the table 34 serves for grinding the cutting edges of drills in connection with the clamping device 35 according to the invention.
  • the clamping device 35 is here by means of an angular base plate 36 on the slot guide 37 of the grinding block 31 adjustable, which slot guide 37 on the grinder block 31 is otherwise used to attach the grinding pad, which is removed here. Otherwise, the clamping device 35 corresponds to that of FIG. 5 and parts 8 to 10 and 12 to 23 for grinding the drill 11; only the end faces 38, 39 are arranged at an angle on the prisms, so that in cooperation with the adjustable feed screw 40 during the pivoting movement C there is a screwing movement for grinding. In the same way as in the first exemplary embodiment, end faces of the prisms arranged at right angles can also be used here.
