Description

L'invention concerne un dispositif pour le bridage latéral de pièces à usiner sur une machine-outil en particulier pour la bridage de pièces difformes ou de grande hauteur.The invention relates to a device for lateral clamping of workpieces on a machine tool, in particular for clamping deformed or very high workpieces.

On connait déjà des dispositifs destinés au bridage vertical de pièces, même de grande hauteur (voir à ce sujet les demandes de brevets françaises n° 77.07.067 du 10 Mars 1977 et n° 78.01.765 du 23 Janvier 1978 appartenant au déposant). Toutefois, ces dispositifs qui procèdent d'un doigt de pression s'appliquant sur la face supérieure de la pièce, ne peuvent pas être utilisés lorsque l'on est en présence des pièces difformes ou surtout de pièces qui doivent être usinées en surface et dont les doigts de pression constitueraient ne gène pour l'opération d'usinage c'est-à-dire pour le passage de l'outil. il est donc usuel dans un tel cas de faire appel à des dispositifs de bridage latéraux prenant appui sur les flancs latéraux de la pièce. Toutefois, tous les dispositifs de ce genre connu présentent l'inconvénient d'une part d'être d'un serrage peu fiable en particulier lorsqu'ils sont destinés à brider des pièces hautes. En effet, dans ce cas, le serrage ne s'effectuant qu'à la base de la pièce, cette dernière si elle est relativement haute à tendance à "balancer" sous les coups de l'outil ce qui peut entrainer son débridage avec toutes les conséquences que cela laisse imaginer en particulier au niveau des risques graves d'accident.There are already known devices intended for vertical clamping of parts, even of great height (on this subject see French patent applications No. 77.07.067 of March 10, 1977 and No. 78.01.765 of January 23, 1978 belonging to the applicant). However, these devices which proceed from a pressure finger applying to the upper face of the part, cannot be used when one is in the presence of deformed parts or especially parts which have to be machined on the surface and whose the pressure fingers would not interfere with the machining operation, that is to say for the passage of the tool. it is therefore usual in such a case to use lateral clamping devices bearing on the lateral flanks of the part. However, all the devices of this known type have the drawback on the one hand of being an unreliable clamping, in particular when they are intended to clamp high parts. Indeed, in this case, the clamping being carried out only at the base of the part, the latter if it is relatively high tends to "swing" under the blows of the tool which can cause its unclamping with all the consequences that this suggests in particular in terms of serious accident risks.

L'invention a pour but de remédier à ces inconvénients et concerne à cet effet un dispositif qui par sa conception et sa facilité d'adaptation, permet le bridage fiable et efficace de toutes pièces à usiner quelque soit leurs formes et leurs hauteurs.The invention aims to remedy these drawbacks and to this end relates to a device which by its design and its ease of adaptation, allows the reliable and efficient clamping of all parts to be machined whatever their shapes and heights.

L'invention concerne donc un dispositif de bridage latéral de pièces à usiner sur une machine-outil caractérisé en ce qu'il est cons: titué d'au moins un coulisseau pourvu d'un élément d'ancrage, mobile en translation dans le coulisseau, sous la poussée d'un organe de pression, la partie active de l'élément d'ancrage,faisant saillie par rapport à la face frontale du coulisseau,comportant au moins une zone de butée rigide et une partie légèrement flexible.The invention therefore relates to a device for lateral clamping of workpieces on a machine tool, characterized in that it is made up of: at least one slide provided with an anchoring element, movable in translation in the slide , under the pressure of a pressure member, the active part of the anchoring element, projecting with respect to the front face of the slide, comprising at least one rigid abutment zone and a slightly flexible part.

Suivant un mode de réalisation préférentiel, l'élément d'ancrage est réalisé en acier ressort et est associé à une vis de commande immobilisée axialement mais mobile en rotation, la partie active de cet élément étant formée de trois doigts cintrés vers le bas, le doigt médian étant en retrait par rapport aux deux doigts latéraux contigus et étant renforcé pour former une zone de butée rigide, tandis que les deux doigts latéraux sont de faible épaisseur afin d'être légèrement flexible, et sonten retrait par rapport à la face inférieure de l'élément d'ancrage pour pouvoir lors de la flexion, se déformer légèrement vers le bas.According to a preferred embodiment, the anchoring element is made of spring steel and is associated with an immobilized control screw axially but movable in rotation, the active part of this element being formed by three fingers bent downwards, the middle finger being set back with respect to the two adjacent lateral fingers and being reinforced to form a rigid abutment zone, while the two lateral fingers are thin in order to be slightly flexible, and are set back with respect to the underside of the anchoring element so as to be able, when bending, to deform slightly downwards.

Suivant une caractéristique de l'invention, on utilise pour le bridage latérale de pièces hautes plusieurs coulisseaux superposés chacun de ceux-ci comprenant une partie mâle et une partie femelle de forme complémentaire pour leur accouplement mutuel, un ergot de verrouillage étant prévu dans chaque coulisseau pour pénétrer partiellement dans lé coulisseau adjacent afin d'éviter tout recul lors du bridage.According to a characteristic of the invention, there are used for the lateral clamping of high parts several superimposed slides each of these comprising a male part and a female part of complementary shape for their mutual coupling, a locking lug being provided in each slide to partially penetrate the adjacent slide in order to avoid any setback during clamping.

Un dispositif de bridage selon l'invention est représenté à titre d'exemple non limitatif sur les figures ci-jointes dans lesquelles :

  • - la Fig. 1 est une vue en coupe longitudinale de deux coulisseaux associés portés par une table de machine-outil,
  • - la Fig. 2 est une vue en coupe de gauche de la Fig. 1,
  • - la Fig. 3 est une vue de dessus schématique de la Fig. 1,
  • - la Fig. 4 est une vue en plan de l'élément d'ancrage,
  • - la Fig. 5 est une vue de dessus de la Fig. 4.
A clamping device according to the invention is shown by way of nonlimiting example in the attached figures in which:
  • - Fig. 1 is a view in longitudinal section of two associated slides carried by a machine tool table,
  • - Fig. 2 is a left sectional view of FIG. 1,
  • - Fig. 3 is a schematic top view of FIG. 1,
  • - Fig. 4 is a plan view of the anchoring element,
  • - Fig. 5 is a top view of FIG. 4.

Le but essentiel de l'invention réside dans la conception particulière d'un dispositif de bridage latéral permettant de fixer sur la table d'une machine-outil des pièces à usiner, quelle que soit la forme de leur contour et surtout quelle que soit leur hauteur.The essential object of the invention lies in the particular design of a lateral clamping device making it possible to fix on the table of a machine tool parts to be machined, whatever the shape of their outline and especially whatever their height.

Ce dispositif est constitué essentiellement d'un profilé en forme d'étrier dénommé ci-après coulisseau. Ce coulisseau 1 dont la section est plus particulièrement visible en Fig. 2 comporte une partie mâle 11 et une partie femelle 12 de forme complémentaire. La partie mâle se présente sous la forme d'une tête parallélépipédique pourvue sur ses deux bords latéraux de deux épaulements 2 en saillie par rapport à la face latérale 3. Ces deux épaulements se raccordent avec la face latérale 3 par deux arêtes légèrement inclinées 4. La artie femelle quant à elle comporte intérieurement un logement 5 ryant une section complémentaire de la tète 11. Chaque coulisseau se présente sous la forme d'un tronçon de profilé et peut être assemblé ivec un coulisseau continu par simple emboitement de la partie mâle d'un coulisseau dans la partie femelle de l'autre.This device essentially consists of a stirrup-shaped profile hereinafter called a slide. This slide 1, the section of which is more particularly visible in FIG. 2 comprises a male part 1 1 and a female part 1 2 of complementary shape. The male part is in the form of a parallelepiped head provided on its two lateral edges with two projecting shoulders 2 with respect to the lateral face 3. These two shoulders are connected with the lateral face 3 by two slightly inclined edges 4. The female part, on the other hand, internally comprises a housing 5 having a complementary section of the head 1 1 . Each slider is in the form of a section of profile and can be assembled ivec a continuous slider by simple fitting of the male part of a slider in the female part of the other.

Chaque coulisseau est par ailleurs pouvu d'un élément d'ancrage 6 monté mobile en translation alternative dans un logement 7 realisé dans la tête 11 du coulisseau. Ce logement 7 ne s'étend que sur une partie de la longueur du coulisseau, la partie postérieure de ce dernier étant obturée par une paroi 8 percée d'un orifice circulaire 9 permettant le passage d'une vis de commande 10. La tête 11 de cette vis est en saillie à l'extérieur par rapport à la face frontale 12 du coulisseau tandis que sa partie avant filetée coopère avec un orifice taraudé 13 ménagé dans l'élément d'ancrage 6. Cette vis comporte par ailleurs un épaulement annulaire 14 venant en appui, en fin de course arrière, contre la paroi postérieure 8 du coulisseau.Each slide is also capable of an anchoring element 6 mounted movable in alternative translation in a housing 7 produced in the head 11 of the slide. This housing 7 extends only over a part of the length of the slide, the rear part of the latter being closed by a wall 8 pierced with a circular orifice 9 allowing the passage of a control screw 10. The head 11 of this screw protrudes outside relative to the front face 12 of the slide while its threaded front part cooperates with a threaded orifice 13 formed in the anchoring element 6. This screw also has an annular shoulder 14 coming to bear, at the end of the rear stroke, against the rear wall 8 of the slide.

L'élément d'ancrage 6, (Fig. 4 & 5), se présente sous la forme d'un bloc parallélépipèdique dont la partie avant dite partie active ou opérationnelle est réalisée sous la forme de trois doigts 61, 62 et 63 ces doigts étant cintrés vers le bas et étant obtenus par de simples coups de scie 15 et 16. Selon une caractéristique essentielle de l'invention, le doigc central 62 présente une nervure de rigidification 64 destinée à le rigidifier afin de constituer une butée qui viendra en appui, lors du bridage sur la pièce P,(Fig. 1.). Au contraire, les deux doigts latéraux 61 et 63 sont de mince épaisseur de manière à être légèrement flexibles, l'élément d'ancrage étant pour ce faire réaliser en acier à ressort (acier 45 S 8).The anchoring element 6, (Fig. 4 & 5), is in the form of a parallelepiped block whose front part called the active or operational part is produced in the form of three fingers 6 1 , 6 2 and 6 3 these fingers being curved downwards and being obtained by simple saws 15 and 16. According to an essential characteristic of the invention, the central finger 6 2 has a stiffening rib 6 4 intended to stiffen it in order to constitute a stop which will come to bear, during clamping on the part P, (Fig. 1.). On the contrary, the two lateral fingers 6 1 and 6 3 are of thin thickness so as to be slightly flexible, the anchoring element being for this purpose made of spring steel (steel 45 S 8).

Afin que les doigts flexibles puissent se déformer vers le bas par cintrage lors de la poussée de bridage qui s'exerce sur cet élément d'ancrage, les doigts 61-63 sont légèrement en saillie par rapport à la face frontale 65 du doigt médian 62 et également en retrait par rapport au plan de référence 66 que constitue la face inférieure de l'élément d'ouvrage 6. Cette conception est destinée à ce que ce soit les doigts latéraux 61 et 63 qui entrent en premier en contact avec la pièce à brider et qu'ils puissent se déformer vers le bas jusqu'à ce qu'ils viennent affleurer avec le niveau de la face inférieure 66 de l'élément d'ancrage . A ce stade, les deux doigts 61 et 63, et plus particulièrement la face frontale sont sensiblement sur le même plan de la face frontale 65 du doigt médian 62 de sorte que les trois doigts sont en appui symétrique sur la pièce à brider. La flexibilité du métal, en particulier, la flexibilité des doigts latéraux 61 63 augmente par simple flexion la pression d'arc-boutement des trois doigts d'ancrage sur la pièce.So that the flexible fingers can deform downward by bending during the clamping thrust which is exerted on this anchoring element, the fingers 6 1 -6 3 are slightly projecting from the front face 6 5 of the middle finger 6 2 and also set back from the reference plane 6 6 that constitutes the underside of the work element 6. This design is intended for the lateral fingers 6 1 and 6 3 to come into first in contact with the workpiece and they can bend down until they come flush with the level of the lower face 6 6 of the anchoring element. At this stage, the two fingers 6 1 and 6 3 , and more particularly the front face, are substantially on the same plane of the front face 6 5 of the middle finger 6 2 so that the three fingers are in symmetrical support on the part to be restrain. The flexibility of the metal, in particular, the flexibility of the lateral fingers 6 1 6 3 increases by simply bending the bracing pressure of the three anchoring fingers on the part.

L'agent de poussée de l'élément d'ancrage est comme indiqué précédemment la vis de commande 10. Celle-ci est immobilisée en translation axiale par un ergot 17 situé dans un plan orthogonal à la vis 10 et venant se loger en partie dans une gorge annulaive 18 dont est pourvue la vis. Ainsi la vis ne peut se déplacer qu'en rotation qui se transforme par un déplacement en translation de l'élément d'ancrage 6 en direction de la pièce P jusqu'à ce que les deux doigts latéraux 61 63 de cet élément d'ancrage entrent en contact avec cette pièce. Si l'on continue à entrainer la vis en rotation, les deux doigts flexibles 61 63 se déforment légèrement vers le bas jusqu'à ce que le doigt médian 62 entre a son tour en contact avec la pièce P. La combinaison de l'élément rigide 62 et des deux éléments flexibles 61 63 présente l'avantage de permettre un arc-boutement efficace et fiable de la partie active de l'élément d'ancrage sur la pièce P.The pushing agent of the anchoring element is, as indicated above, the control screw 10. The latter is immobilized in axial translation by a lug 17 situated in a plane orthogonal to the screw 10 and coming to be housed partly in an annular groove 18 with which the screw is provided. Thus the screw can only move in rotation which is transformed by a translational movement of the anchoring element 6 in the direction of the part P until the two lateral fingers 6 1 6 3 of this element d anchorages come into contact with this part. If the screw continues to be driven in rotation, the two flexible fingers 6 1 6 3 deform slightly downwards until the middle finger 6 2 in turn comes into contact with the part P. The combination of the rigid element 6 2 and two flexible elements 6 1 63 has the advantage of allowing efficient and reliable bracing of the active part of the anchoring element on the part P.

Si la pièce P à brider est relativement haute, on psut, grace à la conception des coulisseaux l,gerber plusieurs de ces coulisseaux c'est-à-dire les assembler par coulissement afin de constituer des étages comme illustré en fig. 2. Les coulisseaux sont immobilisés mutuellement par les ergots 17 qui servent également, comme indiqué précédemment, à l'immobilisation axiale de la vis 10. Ces ergots sont en effet logés dans des trous 19 traversant de part en part la tête du coulisseau de façon à pouvoir venir pénétrer dans 1 orifice. identique prévu sur l'autre coulisseau adjacent. Le déplacement vers le bas de l'ergot 17 est limité par un doigt radial 20 solidaire de cet ergot et se déplaçant dans une lumière 21 débouchant sur la face frontale 12 du coulisseau. Le doigt radial 20 est accessible de l'extérieur de façon à permettre le désaccouplement des coulisseaux par simple déplacement ascensionnel de l'ergot 17 rendu possible par la préhension du doigt radial 20.If the part P to be clamped is relatively high, it is possible, thanks to the design of the sliders l, to stack several of these sliders, that is to say to assemble them by sliding in order to constitute stages as illustrated in FIG. 2. The slides are mutually immobilized by the lugs 17 which also serve, as indicated above, for the axial immobilization of the screw 10. These lugs are in fact housed in holes 19 passing right through the head of the slide to be able to come into 1 orifice. identical provided on the other adjacent slide. The downward movement of the lug 17 is limited by a radial finger 20 integral with this lug and moving in a slot 21 opening onto the front face 12 of the slide. The radial finger 20 is accessible from the outside so as to allow the sliders to be uncoupled by simple upward movement of the lug 17 made possible by gripping the radial finger 20.

Les coulisseaux gerbés peuvent être fixés sur une semelle 22 ayant en section une forme complémentaire de la partie femelle du coulisseau. Cette semelle qui peut se présenter sous la forme d'une barre profilée comporte ponctuellementdes orifices d'ancrage 3 qui la traversent de part en partpour le passage de vis de fixation 24 venant pénétrer dans des talons (non représentés) pourvus d'orifices taraudés et logés dans les rainures en T classiques de la table de la machine-outil. Ces profilés ou semelles 22 peuvent être orientées dans un plan parallèle auxrainures de la table, dans un plan orthogonal ou oblique. Ainsi, l'utilisateur n'est plus tenu à la forme des rainures de la table de la machine-outil ou à leur écartement respectif et peut déplacer ces coulisseaux à volonté sur les semelles 22 et ce, quelle que soit la forme de la pièce, puisque lesdites semelles peuvent être orientées dans des directions différentes. Il est donc possible grâce à cette conception de brider des pièces ayant une forme autre que géométrique en utilisant des barres orientées dans des sens différents, ces barres étant pourvues d'orifices 25 permettant l'immobilisation du coulisseau situé à l'a base de la pile des coulisseaux,l'immobilisation étant là encore obtenue par l'ergot 17 venant pénétrer dans l'orifice 25 de la semelle ou barre 22 elle-même immobilisée sur la table de la machine-outil par les vis 24.The stacked slides can be fixed on a sole 22 having in section a shape complementary to the female part of the slide. This sole, which can be in the form of a profiled bar, punctually has anchoring holes 3 which pass right through it for the passage of fixing screws 24 coming into heels (not shown) provided with threaded holes and housed in the classic T-slots of the machine tool table. These profiles or flanges 22 can be oriented in a plane parallel to the table gears, in an orthogonal or oblique plane. Thus, the user is no longer bound to the shape of the grooves of the table of the machine tool or to their respective spacing and can move these slides at will on the soles 22 and this, whatever the shape of the part. , since said soles can be oriented in different directions. It is therefore possible, thanks to this design, to clamp parts having a shape other than geometric by using bars oriented in different directions, these bars being provided with orifices 25 allowing immobilization of the slide located at the base of the stack of sliders, the immobilization being again obtained by the lug 17 coming into the orifice 25 of the sole or bar 22 itself immobilized on the table of the machine tool by the screws 24.

Enfin, il est possible de combiner ce dispositif de bridage latéral avec un dispositif de bridage vertical tel que ceux décrits et représentés dans les demandes de brevets rappelés dans le préambule de la demande et appartenant au déposant. Cn obtiendrait ainsi et de façon cumulative un bridage latérale de la pièce sur ses flans latéraux et à des hauteurs différentes, plus un bridage vertical fiable permettant ainsi l'usinage en toute sécurité.Finally, it is possible to combine this lateral clamping device with a vertical clamping device such as those described and represented in the patent applications mentioned in the preamble to the application and belonging to the applicant. Cn would thus obtain and cumulatively a lateral clamping of the part on its side blanks and at different heights, plus a reliable vertical clamping thus allowing machining in complete safety.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation ci-dessus décrits qui ne constituent que des exemples, et pour lesquels on pourrait prévoir d'autres variantes ou d'autres moyens sans pour cela sortir du cadre de l'invention.Of course, the invention is not limited to the embodiments described above which are only examples, and for which other variants or other means could be provided without departing from the scope of the invention.
