Definitions

  • This invention relates to a tool for abrasive machining by honing the free-form surfaces, in
  • the honing tool is fitted with several abrasive sticks which are
  • the honing sticks are mounted in a bodu which employs a hydraulic- or pneumatic-system piston.
  • the articulated joint and hydraulic- or pneumatic load provide means of compensation for both stock removed and the abrasive-sticks reduction in size.
  • the abrasive sticks were secured by means of an articulated joint having one degree of freedom with respect to the honing tool.
  • the abrasive-stick axis of rotation in the hone was located above the surface being honed.
  • the force of the stone against the surface being honed was provided by a hydraulic system.
  • abrasive-stick force against the surface being honed was provided by a permanent magnet made in the form of a ring mounted inside the honing tool ring.
  • the abrasive sticks have to be made of expensive materials.
  • the essence of the honing tool manufactured according to this invention consists in the axis of the articulated joint in which the hone os secured, which is located on/in the work piece.
  • the articulated joint is made in the form of a spher i ca l cap.
  • the articulated joint is made in the form of a cylindrical surface sector, if this is a case, a cuboidal abrasive stick is secured in a articulated joint holder so that the angle & between the longer axis of the articulation and the tangent to the circle determined by the centre of the abrasive stick that rotates around the honing tool axis is included between 0° and 90o i.e. 0° ⁇

Abstract

Outil à roder équipé d'ensembles de rodage (2, 3, 4, 5, 6) solidaires d'un élément coulissant. Un bâton dresseur (6) est monté sur une articulation (4). L'axe de rotation (0') de l'articulation (4) se situe sur/dans la pièce à usiner (9). L'articulation (4) a la forme d'une calotte sphérique ou sa surface a une section cylindrique. Le bâton dresseur (6) de forme cuboïde est monté dans un support (5) de ladite articulation cylindrique de telle sorte que l'angle (β) compris entre l'axe long de l'articulation et la tangente du cercle (12) délimité par le centre du bâton dresseur (6) tournant autour de l'axe (0) de l'outil à roder soit compris entre 0° et 90°, c'est-à-dire que 0° <|β|< 90°.
