Definitions

  • the invention relates to a honing tool, which is particularly suitable for honing blind holes.
  • an overflow is required at the top and bottom of the hole.
  • the required overflow usually corresponds to about one third or half of the honing stone length.
  • the actual overflow is determined by the shape of the hole. For example, if the bore is narrower at the top than at the bottom, then a larger overflow is required at the top. If, on the other hand, the hole is narrower at the bottom, then a larger overflow will also be necessary at the bottom.
  • the correct choice of overflow ensures that the bore is always kept straight. In a blind hole, the lower overflow is very limited.
  • the honing tool must be removed relatively often.
  • the honing stone can then be reworked on the honing tool, for example by blending, or a new honing stone must be used.
  • the honing tool according to the invention with the features of claim 1 has the advantage that machining by honing improved and is made possible even with unfavorable geometries. Specifically, even with a slight overflow, it is possible to keep the bore straight. This concerns especially a lower overflow of the bore.
  • a further honing stone segment is provided, that the further honing stone segment is fastened closer to the end of the groin support than the first honing stone segment, that the second honing stone segment can be fastened closer to the end of the groin support than the further honing stone segment and that the further honing stone segment is one Wear resistance which is higher than the wear resistance of the first honing stone segment and which is lower than the wear resistance of the second honing stone segment.
  • the honing stone segments, which are arranged closer to the end wear less quickly than the honing stone segments, which are arranged further away from the end on the rail carrier.
  • the bore in the region of the end would be somewhat wider, but this can be compensated by increasing the overflow on the other side of the bore again.
  • the honing stone segments are assembled with the strip carrier to a honing stone and that the honing stone is loosely arranged in a honing tool body.
  • the honing stone segments are connected by gluing or soldering with the bar support and that the honing stone segments are removed by loosening the connection again.
  • the honing stone segments are here combined to form the honing stone, so that the entire honing stone is connected to the strip carrier by gluing or soldering. If the honing stone is to be replaced by a new honing stone, then the connection of the honing stone with the rail carrier is released.
  • a groove is formed on the strip carrier, in which the honing stone segments can be used in a successive arrangement.
  • the successive arrangement is predetermined by the joining. Due to the successive arrangement of Honleistensegmente a uniform machining of the bore is made possible.
  • the second honing stone segment which has the highest wear resistance, at least substantially adjacent to the end of the rail carrier.
  • the honing stone or the section composed of the honing stone segments consumes less strongly in the region of the end of the grooved support, so that advantageous machining is achieved here, even with a slight overflow, which keeps the bore straight.
  • an end-side shoulder is formed between the second honing stone segment and the end of the strip carrier on which the second honing stone segment is supported. Especially in combination with the groove, into which the honing stone segments are inserted, there is thus a particularly good hold of the honing stone segments on the rail carrier.
  • the honing stone segments are arranged on one side of the honing stone body, that a support strip is provided and that the support strip is arranged on another side of the honing stone body, which faces away from the side of the honing stone body.
  • the first honing stone segment is made longer with respect to a longitudinal axis of the honing stone body than the second longitudinal axis segment.
  • the different wear resistance of the honing stone segments result from different specifications for a grain size and / or grain type and / or bonding and / or concentration of the grains for the honing stone segments.

Abstract

L'invention concerne un outil à roder (1) convenant en particulier pour le rodage de perçages borgnes (5), ledit outil comprenant un support de baguette (3), un premier segment (16) de baguette de rodage et un second segment (17) de baguette de rodage. Selon l'invention, le premier segment (16) de baguette de rodage et le second segment (17) de baguette de rodage sont fixés dans une rainure (22) du support de baguette (3). Le support de baguette (3) comporte en outre une extrémité (10) par laquelle il peut être introduit dans un perçage (5). Le second segment (17) de baguette de rodage est fixé plus près de l'extrémité (10) du support de baguette (3) que le premier segment (16) de baguette de rodage. De plus, le second segment (17) de baguette de rodage possède une résistance à l'usure supérieure à celle du premier segment (16) de baguette de rodage. On peut ainsi roder un perçage (5) maintenu rectiligne même en présence d'un débordement (9) limité.
