Abstract
Description
Cette invention concerne une machine à fretter permettant l'assemblageThis invention relates to a fretting machine for assembling
d'outils coupants dans des attachements spécifiques au frettage thermique. cutting tools in specific attachments to thermal shrinking.
Cette machine utilise la technique connue de l'induction pour le chauffage des porte-outils. This machine uses the known technique of induction for heating tool holders.
Les températures atteintes au niveau des porte-outils sont élevées et dangereuses pour un utilisateur. The temperatures reached at the level of the tool carriers are high and dangerous for a user.
Ainsi, il est difficile de fixer une longueur particulière de sortie de l'outil, avant contraction de l'attachement 10 qui serre la queue de l'outil. Thus, it is difficult to fix a particular length of output of the tool, before contraction of the attachment 10 which clamps the tail of the tool.
Le pré-réglage proposé permet de fretter un outil à une cote, du plan de jauge du cône du porte-outil au bout de l'outil, déterminée à l'avance, sans connaître la longueur ni de l'outil, ni du porte-outil. The proposed pre-setting makes it possible to shrink a tool to a dimension, from the cone gauge plane of the tool holder to the end of the tool, determined in advance, without knowing the length of the tool or the door -tool.
Le principe utilisé consiste à ce que l'outil vienne en contact sur sa partie inférieure sur une tige butée réglée au préalable à une position précise en fonction de la longueur totale outil / porte-outil à obtenir. The principle used is that the tool comes into contact on its lower part on a stop rod previously set to a precise position according to the total length tool / tool holder to obtain.
La figure 1 représente l'assemblage outil / porte-20 outil à obtenir. Figure 1 shows the tool / tool holder assembly to be obtained.
La figure 2 représente le dispositif de pré-réglage par l'arrière avec son guide-outil. Figure 2 shows the pre-setting device from the back with its tool guide.
La figure 3 représente le principe de mise à longueur de la tige butée. Figure 3 shows the principle of setting the length of the stopper rod.
La figure 4 représente l'outil assemblé au porte-outil sur le dispositif de pré-réglage. Figure 4 shows the tool assembled to the tool holder on the presetting device.
Le système de pré-réglage par l'arrière est un dispositif dont le but est de régler une tige butée (4) au travers d'un porte-outil (2), sur laquelle un outil (1) viendra en butée lors de l'assemblage de l'outil dans le porte-outil, et ainsi le solidariser dans une position précise. - 2 The rear pre-adjustment system is a device whose purpose is to adjust a stop rod (4) through a tool holder (2), on which a tool (1) will come into abutment during operation. assembly of the tool in the tool holder, and thus secure it in a precise position. - 2
En fonction du diamètre de la queue de l'outil (1) à assembler au porteoutil (2), le guide-outil (6) correspondant est fixé à la tige butée (4) à l'aide d'une vis de pression (7). Depending on the diameter of the tail of the tool (1) to be assembled to the tool holder (2), the corresponding tool guide (6) is fixed to the stopper rod (4) by means of a set screw ( 7).
L'outil (1) est introduit dans l'alésage du guide-outil (6), en appui sur la tige butée (4). Il est alors positionné à la même position que lorsqu'il sera fretté. A l'aide d'un moyen de mesure approprié (règle de mesure, comparateur, projecteur, ...), une référence, qui sera le zéro mesure, est réalisée sur le plan de jauge du porte-outil (2), qui correspond au plan (3a) du système de pré-réglage. The tool (1) is introduced into the bore of the tool guide (6), bearing on the stop rod (4). It is then positioned at the same position as when it is fretted. Using a suitable measuring device (measuring ruler, comparator, projector, etc.), a reference, which will be the zero measurement, is made on the gauge plane of the tool holder (2), which corresponds to the plane (3a) of the presetting system.
La longueur L à pré-régler est affichée sur le moyen de mesure en déplaçant le curseur (8) (comparateur, projecteur, ...) parallèlement à l'axe du dispositif de pré-réglage. The length L to be preset is displayed on the measuring means by moving the cursor (8) (comparator, projector, ...) parallel to the axis of the presetting device.
En tournant la molette (5) du système de pré-réglage, la tige butée (4) coulisse verticalement jusqu'à ce que l'extrémité de l'outil (1) soit positionnée à la longueur L précise ( zéro du comparateur ou de la mire du projecteur) du moyen de mesure. By turning the knob (5) of the pre-adjustment system, the stopper rod (4) slides vertically until the end of the tool (1) is positioned at the precise length L (zero of the comparator or the sight of the projector) of the measuring means.
L'outil (1) peut alors être retiré du guide-outil (6) et le guide-outil (6) désolidarisé de la tige butée (4). The tool (1) can then be removed from the tool guide (6) and the tool guide (6) disengaged from the stop rod (4).
En introduisant le porte-outil (2) dans le système de pré- réglage (3), son plan de jauge coïncidant avec le plan (3a), sans modifier la position de la tige butée (4) qui traverse le porte-outil (2), l'outil (1) pourra alors être fretté en venant en appui sur la tige butée (4). By introducing the tool holder (2) in the pre-setting system (3), its gauge plane coinciding with the plane (3a), without modifying the position of the stop rod (4) which passes through the tool holder ( 2), the tool (1) can then be fretted bearing on the stop rod (4).
Après refroidissement du porte-outil et la queue de l'outil serrée, l'ensemble outil/porte-outil peut être retiré du système de pré-réglage (3), la tige butée (4) restant, elle, solidaire du système. - 3 After cooling the tool holder and the tail of the tool clamped, the tool / toolholder assembly can be removed from the pre-setting system (3), the stop rod (4) remaining secured to the system. - 3
L'ensemble obtenu aura pour caractéristique la longueur L désirée, sans avoir utilisé la longueur Lo de l'outil ni celle A du porte-outil. The resulting assembly will have the characteristic length L desired, without having used the length Lo of the tool nor that A of the tool holder.
La base (12) de ce dispositif est intégrable à une embase 5 porte-outil ou à un plateau tournant, éléments constitutifs d'une machine à fretter. The base (12) of this device is integrable to a base 5 tool holder or a turntable, constituent elements of a machine to frit.
