Definitions

  • the invention relates to devices according to the preamble of claim 1.
  • This object is achieved in that a separate intermediate member, which is clamped on the one hand in the drill chuck and on the other hand engages in the receptacle, is provided for the drive connection.
  • the separate intermediate link is clamped into the drill chuck of the drill and the device, as far as possible, is plugged onto the spindle neck of the drill and clamped.
  • the intermediate link can be, for example, a hexagonal rod which engages in an engagement recess of the same cross-section in the axis. If the intermediate link is too short and does not reach the axis - short drill chucks - it is clamped less deep into the drill chuck. If it is too long - long chuck, the device does not reach the spindle neck - it can be shortened.
  • the intermediate member is a screw, the shaft of which is clamped in the drill chuck and the head which engages in the receptacle has a non-circular cross section. Such an intermediate link can easily be replaced if lost.
  • the various parts of the exemplary embodiment are arranged concentrically around the central axis 1.
  • An axis consists of a spindle 2, which widens downwards over a shoulder 3 into a grinding wheel carrier 4.
  • the axis has a coaxial recess 6 on the drive side with a wall 5 which widens conically on the drive side.
  • An annular grinding wheel 7 is glued to the grinding wheel carrier 4 with an internally conical grinding surface 8.
  • a drill guide piece 9, 10 is arranged opposite the grinding surface 8. It is composed of a guide channel body 9 and a guide pin plate 10 rigidly connected to it.
  • the spindle 2 of the axes 2 to 4 is supported and the axis is supported by its shoulder 3 against the lower end of the bearing.
  • a screw 12 is screwed axially, the head of which is supported via the insert 13 against the upper end of the bearing.
  • the guide knuckle body 9 has with the axis 2 to 4 parallel guide channels 14, the lower openings of which are directed against the grinding surface 8.
  • the guide channels have different diameters and serve to axially guide drills of different diameters to the grinding surface.
  • the guide pin plate 10 has openings aligned with the guide channels 14, into each of which two guide pins 15, which are intended for engagement in the flutes of a drill, for radially guiding the drill to the grinding surface, project.
  • the drill guide piece 9, 10 is rigidly connected to a housing 16 to 19.
  • the housing 16 surrounds the grinding wheel 7 and narrows down into a clamping sleeve 17, which a Has clamping eye 18 with a clamping screw 19.
  • a separate hissing member 23, 24 consists of a shaft 23 which carries a hexagonal head 24 with a larger cross section.
  • the drive connection between the axes 2 to 4 and the drill chuck 22 of a hand drill 21 is established as follows.
  • the shaft 23 of the intermediate member is clamped in the drill chuck.
  • the device is pushed over the drill chuck and the spindle neck 20 of the drilling machine until the head 24 of the intermediate member penetrates into the recess 6 in the axis.
  • the device is pressed against the head 24 of the intermediate member, which wedges in the conical wall 5, and the clamping screw 19 is tightened.
  • the device is ready for use. If the intermediate link does not reach the axis, it is clamped less deep in the drill chuck. If the device does not reach the spindle neck 20, the shaft 23 of the intermediate member is shortened accordingly.
  • the intermediate link 23, 24 is dimensioned such that it can be replaced by a corresponding standard screw if lost.
  • the drill to be ground is inserted into the smallest suitable guide channel 14 and ground in a known manner.
