Definitions

  • DE-PS 290 422 describes a grinding wheel of the type mentioned at the outset, in which the distance between the two partial wheels, which are provided with alternating claw-like grinding segments, can be changed to adjust the overall width of the grinding wheel. This change in the mutual spacing of the indexing disks is accomplished by turning a nut which engages in a thread fastened in the indexing disk. Special means must be provided to keep the indexing disks in the set position.
  • these are - in plan view - preferably essentially triangular or trapezoidal, with the larger base lying on the outer edge of the associated part-disk support body.
  • the drive toothed ring can be arranged concentrically with the two partial disk support bodies and can be in drive connection with all adjusting elements. This ensures that the two partial disk support bodies can be adjusted uniformly over their entire circumference with little structural effort.
  • the two part-disk support bodies can be clamped together by means of tensioning screws, in each case in the position which permits the position of the adjusting elements.
  • the position of the partial disk support body, which does not have the internal thread for receiving the adjusting elements, lies evenly all around on the free end faces of the adjusting elements.
  • the adjusting elements can be essentially hollow cylindrical and the tensioning screws can be passed through the adjusting elements.
  • the two part disk support bodies advantageously always being clamped together precisely at the points at which the adjusting elements also act as spacers. This ensures high latitude accuracy.
  • grinding spindle bearings are preferably provided on both sides of the flanges of the grinding spindle.
  • the disk body 17 is subdivided into two disk-like, preferably metal, part-disk support bodies 1, 2, which are axially adjustable relative to one another and have claw-like interlocking engagement segments on their outer circumference across the entire width of the grinding disk 9, carrying the abrasive coating 16 or formed therefrom.
  • the two partial disk support bodies 1, 2 themselves have claw-like projections distributed over their circumference, which are coated, for example, with diamond grain or CBN on the outside diameter and on the sides.
  • the ceramic-bonded grinding segments 3, 4 are cemented onto the part-disk support bodies 1, 2 with annular groove connection surfaces 18. A direct coating of the claw-shaped lugs of the two part-disk support bodies 1, 2 is also conceivable.
  • the entire grinding wheel 9 is firmly screwed to a grinding spindle 10 via a flange 11 by means of bolts 22 (FIGS. 1 and 4).
  • grinding spindle bearings 12, 13 are provided on the grinding spindle 10 (FIG. 5), which are part of the grinding spindle 10 as ring bodies.
  • the entire spindle set is changed when the grinding wheel is changed.
  • the lateral run (stroke) is unchanged when the grinding machine is converted to a different grinding task, for example.

  4. Meule de rectification selon la revendication 2 ou 3, caractérisée par le fait que les segments abrasifs (3, 4) et/ou la couche de revêtement (16) sont fixées, par exemple collés, par l'intermédiaire de surfaces de liaison (18) en forme de gorges annulaires sur le corps de base de préférence métallique du porte-meule (1,2) concerné.
  5. Meule de rectification selon l'une des revendications 1 à 4, caractérisée par le fait que les éléments de réglage (5) sont disposés sur le cercle primitif avec le même écart angulaire entre eux.
  6. Meule de rectification selon l'une des revendications 1 à 5, caractérisée par le fait que la couronne dentée (6) d'entraînement est concentrique aux deux porte-meules (1).
  7. Meule de rectification selon l'une des revendications 1 à 6, caractérisée par le fait que la couronne dentée (6) d'entraînement est entraînée par un pignon (7) qui est monté dans l'un des porte-meules (1).
  8. Meule de rectification selon la revendication 7, caractérisée par le fait que le pignon (7) d'entraînement est pourvu côté face frontale d'une cavité (21) pour l'engagement d'un outil d'entraînement.
  9. Meule de rectification selon l'une des revendications 1 à 8, caractérisée par le fait que les deux porte-meules (1, 2) sont serrés l'un contre l'autre par des vis de serrage (8).
  10. Meule de rectification selon la revendication 9, caractérisée par le fait que les éléments de réglage (5) sont agencés essentiellement sous la forme de cylindres creux et les vis de serrage (8) traversent les éléments de réglage (5).
  11. Meule de rectification selon l'une des revendications 1 à 10, caractérisée par le fait qu'elles peuvent être fixées par vis sur un flasque (11) de la broche de rectifieuse (10).
