Abstract

The system has cutting tools (2) with shanks (2a) of different diameters, where the tools are fitted in bores of respective reducers (1) by a fitting machine. The bores have different diameters related to the shanks. The reducers are fitted in a single tool holder (3). Each reducer has a tapping for its fixing on a screw of a mounting that is adapted on the fitting machine, for fitting the tools in the respective reducers.

Description

- 1 -- 1 -

Cette invention concerne la technique connue du frettage thermique qui permet d'obtenir des assemblages outils coupants / porte-outils avec des concentricités très précises.  This invention relates to the known technique of thermal shrinking which makes it possible to obtain cutting tool / toolholder assemblies with very precise concentricities.

Un inconvénient à cette technique peut-être le fait qu'un porte-outil donné ne peut être utilisé que pour un seul diamètre de queue d'outil. En conséquence, chaque outil de diamètre de queue différent oblige à utiliser un porte-outil différent.  A disadvantage of this technique may be that a given toolholder can only be used for a single tool shank diameter. As a result, each tool of different tail diameter requires the use of a different tool holder.

L'invention décrite ci-après permet de palier à ce problème.  The invention described below makes it possible to overcome this problem.

Elle consiste à utiliser une réduction permettant d'assembler des outils de différents diamètres de queue dans un seul porte-outil en gardant les avantages de la technique du frettage.  It consists in using a reduction allowing to assemble tools of different diameters of tail in a single tool holder while keeping the advantages of the technique of the hooping.

La figure 1 représente le dispositif de réduction. La figure 2 représente un exemple de montage pour le frettage de l'outil dans la réduction.  Figure 1 shows the reduction device. Figure 2 shows an example of mounting for the hooping of the tool in the reduction.

La figure 3 représente un ensemble outil / réduction / 20 porte-outil monté.  Figure 3 shows a mounted tool / reduction / toolholder assembly.

L'outil (2) est d'abord fretté dans l'alésage (la) de la réduction (1). Pour faciliter l'opération de frettage en toute sécurité, la réduction possède un taraudage (lb) du coté opposé à celui de l'outil pour la fixer par la vis (4a) à un montage (4), lui-même adaptable sur une machine à fretter.  The tool (2) is first wrapped in the bore (la) of the reduction (1). To facilitate the hooping operation safely, the reduction has a tapping (lb) on the opposite side to that of the tool to fix it by the screw (4a) to a mounting (4), itself adaptable on a fretting machine.

On utilise une réduction (1) différente pour chaque diamètre de queue d'outil (2a).  A different reduction (1) is used for each tool shank diameter (2a).

La réduction (et l'outil fretté dans celle-ci) est frettée 30 elle-même dans le porte-outil (3).  The reduction (and the shrink fit therein) is itself shrunk into the tool holder (3).

Plusieurs réductions de même diamètre extérieur, mais de diamètres d'alésage (la) différents (pouvant accueillir différents diamètres de queue d'outil (2a)), peuvent être frettées dans un seul porte-outil (3). - 2 -  Several reductions of the same outer diameter, but different bore diameters (la) (which can accommodate different tool tail diameters (2a)), can be shrunk into a single tool holder (3). - 2 -

Les réductions sont percées de part en part et donc compatibles avec les systèmes d'arrosage central.  The reductions are pierced through and therefore compatible with central irrigation systems.

Ainsi, avec un seul porte-outil à fretter, il est possible de fretter toute une gamme de queues d'outils différentes.  Thus, with a single tool holder to fret, it is possible to frit a whole range of different tool tails.

Le défrettage s'effectue de façon inverse. - 3 -  Deburring is done in the opposite way. - 3 -
