Definitions

  • the present invention relates to a tool with an exchangeable cutting edge for milling for treating floors and / or waste according to the preamble of claim 1.
  • Such milling machines generally have a working element which consists of a drum with a horizontal axis of rotation, which carries holders in the radial direction, which are distributed at various points on the drum shell and which, for example, in FIG tools in the form of mallets.
  • the individual tools can be stored in the various brackets by positive locking, which is detachable via a removable, the tool locking the holder in its receptacle.
  • the tools are therefore encompassed by their inclusion in the holder with the exception of the cutting edge.
  • the object of the present invention is therefore to solve the problem of fastening, for example in the form of a screw, and to propose a tool whose cutting edge can be attached quickly and without endangering the form closure between the holder on the drum and the tool itself.
  • a receptacle intended to receive the cutting edge is provided in the part of the tool that is not subject to the form fit, and that a blind hole is provided in the body that is claimed by the form fit and the receptacle is crossed with the blind hole allows a pin to be inserted in the blind hole be inserted, which penetrates a through hole in the cutting edge and thereby holds it in position.
  • the pin is a set screw and that Blind hole a threaded hole, the threaded pin penetrating the through hole of the insert penetrating with the threaded hole of the body is more or less usable.
  • the pin inserted in its blind hole is simply prevented from coming out of it by the fact that the entry of the blind hole is covered by the positive locking, namely by the part of the holder in which the tool is held stably by a removable shaped piece becomes.
  • the shaped piece is provided with a screw and the tool has a threaded hole in which this screw engages, the shaped piece being fixed to the holder in such a way that the tool is removed from the holder seat after the screw of the shaped piece has been loosened can.
  • the blind hole is in one between two mutually parallel ribs formed recess of the tool body except each lying in a plane perpendicular to the axis of rotation of the milling cutter.
  • the axis of the blind hole receiving the pin is very preferably perpendicular to the pull-out direction from the holder receiving the tool.
  • reference number 1 generally indicates the body of an invention according to the tool executed.
  • the tool is formed from a cylindrical tool foot 2 and a tool head 3.
  • the tool foot 2 and the tool head 3 are partially positively received by a holder 13 shown, as described in the above-mentioned Italian patent, to which reference is made for further explanations.
  • two ribs 4 extend in the tool head 3 and form a recess 5 between them.
  • a receptacle 6 is excluded, which receives a cutting plate 7 forming the cutting edge of the tool.
  • the insert 7 has a through bore 8 which can be aligned with a blind hole 9 which is recessed in the recess 5 in such a way that a pin 10 can be inserted therein, which therefore penetrates the insert to hold it in position.
  • the pin 10 is dimensioned such that it is completely let in or caught in the blind hole 9. The pin 10 is held in this position by the thread and can be released by unscrewing the cutting plate 7.
  • a fitting 11 is provided with a screw 12 and the tool has a threaded hole in which this screw 12 engages, the fitting 11 being fixed to the holder 13 such that the tool after loosening the screw of the fitting can be removed from the seat

Abstract

L'invention concerne un outil à lame interchangeable destiné à des fraiseuses pour le traitement de sols ou de déchets. L'outil selon l'invention présente un contour qui se situe dans un plan de projection perpendiculaire à l'axe de rotation de la fraiseuse et qui comprend une partie au moins partiellement entourée par liaison de forme par un siège d'une fixation de la fraiseuse, ainsi qu'une partie libre hors de laquelle la lame d'outil fait saillie. Le siège de la fixation est formé d'un segment fixe et d'un segment servant à libérer l'outil. Selon l'invention, le corps (1) de l'outil comprend, dans sa partie libre, un logement (6) pour recevoir la base d'une lame (7) et, dans sa partie logement, un trou borgne (9) chevauchant le logement (6) et destiné à recevoir une broche (10). La base de la lame (7) présente un alésage traversant (8) qui est complémentaire du trou borgne (9) dans le corps (1) et qui sert au passage de la broche (10).
