Abstract

The tool tail (3) is abutted on a stop rod (8) adjustable in height by an adjusting knob (5) during installation. A height indicator (11) allows precise adjustment of the stop rod position.

Description

l'oxydation. - 1 Cette invention concerne une machine à fretter permettantoxidation. - 1 This invention relates to a fretting machine allowing

l 'assemblage d'outils coupants dans des  the assembly of cutting tools in

attachements spécifiques au frettage thermique.  attachments specific to thermal shrinking.

Cette machine utilise la technique connue de l' induction pour le chauffage des porte-outils. Les températures atteintes au niveau des porte-outils  This machine uses the known technique of induction for heating tool holders. The temperatures reached in the tool holders

sont élevoes et dangereuses pour un utilisateur.  are high and dangerous for a user.

De plus, il est difficile de fixer une longueur particulière de sortie de l'outil, avant contraction de  In addition, it is difficult to fix a particular length of tool outlet, before contraction of

l'attachement qui serre la queue de l'outil.  the attachment which grips the tail of the tool.

Deux principes de pré-réglage peuvent être utilisés: suivant l'un, l'outil vient en contact sur sa partie inférieure sur une tige butée réglable pendant l'opération de frettage, suivant l'autre, un élément mécanique est fixé à l'outil et vient en butée sur l'extrémité  Two pre-setting principles can be used: according to one, the tool comes into contact on its lower part on an adjustable stop rod during the shrinking operation, according to the other, a mechanical element is fixed to the tool and comes to a stop on the end

Le refroidissement est effectué par des bagues coniques réfrigérantes situées dans un satellite coulissant verticalement. L'utilisateur amène le  Cooling is carried out by conical cooling rings located in a vertically sliding satellite. The user brings the

La figure 2 représente le dispositif de pré-réglage par  Figure 2 shows the pre-setting device by

l' avant.the front.

La figure 3 représente le dispositif de refroidissement.  Figure 3 shows the cooling device.

Le pré-réglage par l'arrière (figure 1) est un dispositif dont le but est de régler une pige de hauteur (8) au travers du porte-outil (1), sur laquelle l'outil (3) viendra en butée lors de l 'assemblage de l'outil dans le porte-outil, et ainsi régler la longueur d' introduction  The rear pre-adjustment (Figure 1) is a device the purpose of which is to adjust a height rod (8) through the tool holder (1), on which the tool (3) will come into abutment when of the tool assembly in the tool holder, and thus adjust the insertion length

de la queue de l'outil dans le porte-outil.  of the tool shank in the tool holder.

Une molette (5) déplace verticalement la pige de hauteur (8), suivant le diamètre de l'outil (longueur normalisée correspondante) ou pour une longueur particulière affichée  A wheel (5) moves the height rod vertically (8), depending on the diameter of the tool (corresponding standard length) or for a particular length displayed

par le témoin de hauteur (11).by the height indicator (11).

L'assemblage de l'outil au porte-outil se fera en amenant  The assembly of the tool to the tool holder will be done by bringing

l'outil en butée sur la pige de hauteur (8).  the tool in abutment on the height rod (8).

- 2 Une fois la queue de l'outil serrée, l 'ensemble outil/porte-outil peut être retiré du système de pré réglage, la pige de hauteur (8) restant, elle, solidaire  - 2 Once the tool shank is tight, the tool / tool holder assembly can be removed from the pre-adjustment system, the height rod (8) remaining integral

Cette technique oblige à tolérancer la cote A (longueur du plan de jauge de l'attachement à l'extrémité supérieure du porte-outil) à plus ou moins O.Olmm (non prévu par la  This technique requires tolerating dimension A (length of the gauge plane of the attachment at the upper end of the tool holder) to more or less O.Olmm (not provided for by the

norme DIN69882-2).DIN69882-2).

La base (12) de ce dispositif est intégrable à une embase porte-outil ou à un plateau tournant, éléments  The base (12) of this device can be integrated into a tool holder base or a turntable, elements

constitutifs d'une machine à fretter.  components of a fret machine.

Le pré-réglage par l' avant (figure 2) est une alternative au pré-réglage par l'arrière. Le but de ce dispositif est de fixer une bague butée (24) à l'outil  Pre-setting from the front (Figure 2) is an alternative to pre-setting from the rear. The purpose of this device is to fix a stop ring (24) to the tool

suivant la longueur de sortie désirée.  depending on the desired outlet length.

Pour cela, une molette (21) déplace verticalement une butée réglable (22) qui vient monter ou descendre l'outil,  For this, a wheel (21) vertically displaces an adjustable stop (22) which raises or lowers the tool,

qui est guidé par la bague de guidage (23).  which is guided by the guide ring (23).

La différence dimensionnelle, mesurée à l 'aide d'un palpeur sur une colonne de mesure, entre la face supérieure de la bague de guidage (23) et la pointe de l'outil, constitue la longueur de sortie que nous voulons pré-regler. Une fois cette longueur ajustée, une vis permet de solidariser la bague butée (24) (qui est également  The dimensional difference, measured using a probe on a measuring column, between the upper face of the guide ring (23) and the tip of the tool, constitutes the length of outlet that we want to preset . Once this length has been adjusted, a screw is used to secure the stop ring (24) (which is also

compatible à l'opération de frettage) à l'outil.  compatible with the shrinking operation) with the tool.

L'assemblage de l'outil au porte-outil se fera en amenant la bague butée (24) en contact avec la partie supérieure du porte-outil. Une fois la quene de l'outil serrce, la  The tool is assembled to the tool holder by bringing the stop ring (24) into contact with the upper part of the tool holder. Once the tool has been tightened, the

bague butée (24) peut être ôtée de l'outil.  stop ring (24) can be removed from the tool.

Le refroidissement (figure 3) est assuré par des bagues coniques (32) venant en contact sur le porte-outil  Cooling (Figure 3) is provided by tapered rings (32) coming into contact on the tool holder
