The tip is fastened by means of a countersunk-head (5a) screw (5) bearing on the cutting tip and screwing into the body of the tool holder, pressing the tip onto the bottom and against the rims. One of the rims consists of the head (4a), which has the shape of a truncated cone (6a) with the large base at the bottom, of an adjusting screw (4) embedded in the body.

Description

Certains dispositifs connus de fixation d'une plaquette de coupe sur le corps d'un porte-outil comportent une vis à tête conique qui prend appui sur la plaquette de coupe, le corps du porte-outil étant pourvu d'un logement avec un fond et deux rebords. Certain known devices for fixing a cutting insert to the body of a tool holder comprise a conical head screw which bears on the cutting insert, the body of the tool holder being provided with a housing with a bottom. and two ledges.

En vissant la vis dans le corps du porte-outil, on plaque la plaquette contre le fond du logement et contre les deux rebords de ce dernier, grâce à une excentration du filetage du corps du porte-outil par rapport a l'axe du trou de la plaquette à fixer.By screwing the screw into the body of the tool holder, the plate is pressed against the bottom of the housing and against the two edges of the latter, thanks to an eccentricity of the thread of the body of the tool holder relative to the axis of the hole. of the plate to be fixed.

Ces dispositifs ne permettent aucun réglage de la position de la plaquette par rapport à son support. Or, il s'est avéré qu'une possibilité de réglage pouvait présenter un intéret notamment pour effectuer des réglages fins ou micrométriques. These devices do not allow any adjustment of the position of the plate relative to its support. However, it turned out that a possibility of adjustment could be of interest in particular for making fine or micrometric adjustments.

L'invention concerne un dispositif simple pour effectuer de tels réglages. The invention relates to a simple device for making such adjustments.

A cet effet, elle a pour objet un dispositif de réglage micrométrique d'une plaquette de coupe fixée dans le logement d'un support comportant un fond et deux rebords d'appui au moyen d'une vis à tête conique prenant appui sur la plaquette de coupe et se vissant dans le corps du porte-outil en plaquant la plaquette sur le fond et lesdits rebords. Selon l'invention, l'un au-moins des rebords susdits est constitué par la tête en tronc de cône à grande base inférieure d'une vis de réglage implantée dans le support susdit au voisinage de la plaquette. To this end, it relates to a device for micrometric adjustment of a cutting insert fixed in the housing of a support comprising a bottom and two support flanges by means of a conical head screw bearing on the insert. cutting and screwing into the body of the tool holder by pressing the plate on the bottom and said flanges. According to the invention, at least one of the abovementioned flanges consists of the truncated cone head with large lower base of an adjustment screw located in the above-mentioned support in the vicinity of the plate.

De manière préférée, la tête de la vis de réglage se prolonge sous la grande base du tronc de cône susdit par une portée cylindrique de guidage coopérant avec le rebord cylindrique correspondant d'un logement ménagé dans le support en inter-section avec le logement de la plaquette. Preferably, the head of the adjustment screw extends under the large base of the aforementioned truncated cone by a cylindrical guide surface cooperating with the corresponding cylindrical rim of a housing formed in the support in cross-section with the housing of the brochure.

L'invention sera mieux comprise au cours de la description donnée ci-après à titre d'exemple purement indicatif et non limitatif qui permettra d'en dégager les avantages et les caractéristiques secondaires. The invention will be better understood during the description given below by way of purely indicative and nonlimiting example which will make it possible to identify the advantages and the secondary characteristics thereof.

Il sera fait référence aux dessins annexés dans lesquels
- la figure 1 est une vue schématique en plan du dispositif selon l'invention,
- la figure 2 est une vue en coupe II-II de la figure 1
En se reportant à ces figures, on voit un support 1 ou corps de porte-outil pourvu d'un logement 2 d'extrémité sur une plaquette 3 délimité par une surface de base 2a, un premier rebord 2b et un second rebord-constitué par la tête 4a d'une vis 4 décrite plus en détail ci-après. La plaquette est fixée dans ce logement par une vis 5 à tête Sa conique. La tête Sa présente de manière connue une certaine exceatration par rapport au trou de la plaquette ce qui permet, lors du vissage de cette dernière de plaquer la plaquette sur le fond 2a, le rebord 2b et la tête 4a de la vis 4.
Reference will be made to the accompanying drawings in which
FIG. 1 is a schematic plan view of the device according to the invention,
- Figure 2 is a sectional view II-II of Figure 1
Referring to these figures, we see a support 1 or tool holder body provided with an end housing 2 on a plate 3 delimited by a base surface 2a, a first flange 2b and a second flange-constituted by the head 4a of a screw 4 described in more detail below. The plate is fixed in this housing by a screw 5 with a conical Sa head. The head Sa has, in a known manner, a certain excitement with respect to the hole in the plate, which allows, when the latter is screwed, to press the plate on the bottom 2a, the rim 2b and the head 4a of the screw 4.

La tête 4a de cette vis possède une surface extérieure 6 tronconique dont la grande base est du cêté de la base de la tête. La pente de cette surface est voisine de la pente de la dépouille 3a que possède de manière connue la plaquette de coupe sur ses quatre bords. Sous cette surface conique 6, la tête de vis présente une portée cylindrique 7 pour son guidage dans le corps d'outil. Ce dernier comporte à cet effet un logement 8 dont les bords 8a enferment la partie cylindrique 7 sur la presque totalité de sa périphérie. Ce logement 8 est placé de manière à être sécant avec le logement 2 de la plaquette 3. The head 4a of this screw has a frustoconical outer surface 6, the large base of which is on the side of the base of the head. The slope of this surface is close to the slope of the draft 3a that the cutting insert has in known manner on its four edges. Under this conical surface 6, the screw head has a cylindrical surface 7 for guiding it in the tool body. The latter comprises for this purpose a housing 8 whose edges 8a enclose the cylindrical part 7 over almost all of its periphery. This housing 8 is placed so as to intersect with the housing 2 of the wafer 3.

La vis 4 de réglage possède un moyen de manoeuvre (ici un six pans creux 4b) pour son vissage ou son dévissage.The adjusting screw 4 has an operating means (here a hexagon socket 4b) for its screwing or unscrewing.

Le réglage de la plaquette s'opère de la manière suivante (avec l'aide d'un instrument de mesure précis : comparateur ou analogue). On place la plaquette dans son logement que l'on assujettit par un serrage doux de la vis 5. La vis 4 est placée par exemple'dans sa position basse (traits mixtes sur la figure 2). L'action de la vis 5 porte la plaquette 3 au contact de la surface 6 de la vis (et du rebord 2b). The adjustment of the plate is carried out as follows (with the aid of a precise measuring instrument: comparator or the like). The plate is placed in its housing which is secured by gently tightening the screw 5. The screw 4 is placed for example in its low position (dashed lines in FIG. 2). The action of the screw 5 brings the plate 3 into contact with the surface 6 of the screw (and the flange 2b).

En remontant la vis 4, on tend à repousser la plaquette vers l'extérieur en provoquant une flexion de la tête Sa de la vis 5 par rapport au corps de vis (A sur la figure 2 illustrant la flexion maximale de la tête quand la vis est remontée au maximum c'est-à-dire dans sa position représentée en trait plein). On bloque ensuite la vis 5 lorsque la plaquette est dans la position désirée. L'effort encaissé par la vis 4 est supporté par les parois 8a du logement 8 qui enserrent de très près la portée cylindrique 7 susdite. Il en est de même si l'on veut réaliser un réglage dans le sens de la rétraction de la plaquette. Le serrage initial de la vis 5 provoquant une flexion de sa tête, les déplacements de la plaquette sont assurés par cette flexion qui joue le ralle de rappel élastique lors des mouvements montants ou descendants de la vis 4. Going up the screw 4, we tend to push the plate outwards by causing the head Sa of the screw 5 to bend relative to the screw body (A in FIG. 2 illustrating the maximum bending of the head when the screw is raised to the maximum, that is to say in its position shown in solid lines). The screw 5 is then blocked when the plate is in the desired position. The effort collected by the screw 4 is supported by the walls 8a of the housing 8 which very closely enclose the cylindrical surface 7 above. It is the same if you want to make an adjustment in the direction of retraction of the wafer. The initial tightening of the screw 5 causing its head to bend, the movements of the wafer are ensured by this bending which plays the elastic return movement during the up or down movements of the screw 4.

L'invention est très simple à réaliser et de ce fait très facile à mettre en oeuvre. The invention is very simple to carry out and therefore very easy to implement.

Elle n'est pas limitée à la description qui vient d'en être donnée mais couvre au contraire toutes les variantes qui pourraient lui être apportées sans sortir de son cadre ni de son esprit. It is not limited to the description which has just been given, but on the contrary covers all the variants which could be made to it without departing from its scope or its spirit.

Elle trouve une application intéressante dans le domaine des industries mécaniques. It finds an interesting application in the field of mechanical industries.
