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 axle 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-C-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 perpendicular to the slide 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 supported, 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, which serves to fix the position of the stand and that an upstanding 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 jaws which intermesh with their teeth in a comb-like manner and can be moved relative to one another by means of a clamping screw, and that an approximately wedge-shaped, approach tapering against the tip of the drill to be clamped and in each case a hole is provided through which the clamping jaw on the stand can be put onto the horizontal axle bolt, the projection of the clamping jaws having prismatic surfaces and the clamping jaws of the clamping device being displaceable with respect to one another by means of transverse guide pins of a lateral retaining strip and the clamping screw is screw-mounted in the retaining bar.
  • a holding piece is known as a U-shaped guide piece encompassing the prisms with the legs, the outer prism being fixed in its position between the ends of the legs and the inner prism by means Pressure screw for clamping the drill is displaceable and the drill can be received in two opposite, angular longitudinal grooves between the prisms. All in all, this is a complex drill maintenance.
  • 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 give perfect accuracy, which is also suitable for a wide range of different drill strengths.
  • the device is characterized in that the stand piece has a feed screw as a stop for the prisms parallel to the axle bolt, which also makes it easy to achieve a high degree of grinding symmetry when repositioning the holding piece with prisms for the drill receptacle for regrinding the drill tip on both sides results, and furthermore, that the prisms have different longitudinal grooves on both sides in the form of angular incisions for receiving different drill diameters, so that drills of different diameter sizes can be regrind with the same device.
  • 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 arranged to be rotatable, height-adjustable and lockable perpendicularly thereto by means of screw axis 9 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 its leg ends 13 a transverse outer prism 14 with U-grooves 15 on both sides can be inserted and fixed by means of screws 16 and a second transverse inner prism 17 with U-grooves 18 on both sides inside the U-shaped guide piece 12 at a distance from the first prism a is adjustable.
  • 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 to fix it 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.
  • the blind holes 22, 23 on the end faces 24, 25 of the prisms 14 and 17 are used 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 serving as a depth-adjustable stop for the removable 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 U of 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 is used 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 here, 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.
