Tete de bridage comportant un pilote de centrage a griffes de serrage retractables L' invention se rapporte au domaine des outils de serrage et elle concerne plus particulierement une tete de bridage pour le The clamping head comprising a centering pilot with retractable clamping claws The invention relates to the field of clamping tools and more particularly relates to a clamping head for the
maintien ou le serrage de piaces.maintenance or tightening of parts.
De telles fetes de bridage vent utilisees dans l'industrie pour maintenir ou mettre en reference des pieces a assembler. Wiles trouvent en particulier une application dans les chalnes d'assemblage d'elements de structure ou de carrosserie de vehicules automobiles. Les pieces ainsi bridees vent alors assemblees par tout moyen connu, notamment par soudage, collage, clinchage, etc. La tete de bridage est montee soit sur un bane d' assemblage fixe, soit a l 'extremite diun bras de robot, soit encore sur une palette mobile, sur un convoyeur Such bridle parties are used in the industry to maintain or reference parts to be assembled. Wiles find in particular an application in the chalnes of assembly of structural elements or bodywork of motor vehicles. The pieces thus flanged are then assembled by any known means, in particular by welding, gluing, clinching, etc. The clamping head is mounted either on a fixed assembly bane, or at the end of a robot arm, or on a mobile pallet, on a conveyor
aerien ou au sol.air or ground.
Plus precisement, l' invention concerne une tete de bridage pour le centrage et le serrage d'au moins une piece possedant un trou de centrage, tete constituee d'un etage mecanique couple a un etage de puissance, l'etage mecanique comprenant un corps, un pilote de centrage apte a faire saillie hors du corps, et au More specifically, the invention relates to a clamping head for centering and clamping at least one piece having a centering hole, head consisting of a mechanical stage coupled to a power stage, the mechanical stage comprising a body , a centering pilot capable of projecting out of the body, and at
moins une griffe de serrage retractable dans le pilote. minus a retractable claw in the pilot.
On connat deja des dispositifs de ce type. Dans un premier type connu, la tete de serrage comprend une simple broche qui s'escamote completement dans un corps et qui est ensuite sortie We already know devices of this type. In a first known type, the clamping head comprises a single pin which retracts completely into a body and which is then removed
pour s'engager dans le trou calibre de centrage d'une piece. to engage in the gauge centering hole of a part.
Dans un deuxieme type connu, la broche est en attente et deja sortie en partie du corps. Wile est ensuite sortie un peu plus, par exemple de 5 mm environ, et des griffes recourbees qui etaient escamotees dans la broche font saillie pour prendre In a second known type, the spindle is on hold and has already left part of the body. Wile then came out a little more, for example about 5 mm, and curved claws which were retracted in the spindle protrude to take
appui sur la piece autour du trou calibre. support on the piece around the gauge hole.
283711 8283 711 8
Ces dispositifs connus ne permettent pas d'assurer a la fois le centrage et le serrage de la piece tout en permettant These known devices do not ensure both centering and clamping of the part while allowing
simultanement un effacement complet de la broche dans le corps. simultaneously a complete erasure of the spindle in the body.
L' invention a notamment pour but de remedier a cet inconvenient. A cet effet, le pilote est apte a se deplacer entre une position rentree dans laquelle il est entierement efface dans le corps et une position de centrage dans laquelle il penetre dans le trou de centrage de la piece, la ou chaque griffe de serrage etant mobile entre une position escamotee dans laquelle elle est contenue dans le pilote et une position de serrage The object of the invention is in particular to remedy this drawback. To this end, the pilot is able to move between a retracted position in which he is completely erased in the body and a centering position in which he enters the centering hole of the part, the or each clamping claw being movable between a retracted position in which it is contained in the pilot and a clamping position
dans laquelle elle serre la piece sur une surface de reference. in which it clamps the part on a reference surface.
Dans une realisation preferee, la tete de bridage comporte un premier ensemble mobile en translation par rapport au corps et un second ensemble monte sur le premier ensemble mobile et mobile en translation par rapport a ce dernier, le second ensemble incluant le pilote et la ou les griffes de serrage, le premier et le second ensemble etant apses a se deplacer d'un bloc de la position rentree jusqu'a la position sortie du pilote puts, le deplacement du premier ensemble se poursuivant, le second ensemble etant apte a se deplacer relativement au premier ensemble, de manibre a provoquer le passage de la griffe de serrage de la position escamotee a la position de serrage. Ainsi, la course du premier ensemble, et particulierement la course du pilote, se divise en deux etapes. Dans une premiere etape, le pilote fait saillie hors du corps pour penetrer dans le trou de centrage, chaque griffe etant escamotee. Dans une deuxieme etape, le pilote etant complatement sorti du corps, la ou chaque griffe de serrage fait saillie hors du pilote pour In a preferred embodiment, the clamping head comprises a first assembly movable in translation relative to the body and a second assembly mounted on the first movable assembly and movable in translation relative to the latter, the second assembly including the pilot and the clamping claws, the first and the second assembly being able to move one block from the retracted position to the extended position of the puts pilot, the displacement of the first assembly continuing, the second assembly being able to move relatively in the first set, so as to cause the passage of the clamping claw from the retracted position to the clamping position. Thus, the race of the first set, and in particular the race of the pilot, is divided into two stages. In a first stage, the pilot projects out of the body to penetrate the centering hole, each claw being retracted. In a second step, the pilot being completely out of the body, the or each claw protrudes out of the pilot to
venir en position de serrage contre la piece. come into clamping position against the workpiece.
Selon une realisation particuliere, le second ensemble comporte According to a particular embodiment, the second set comprises
283711 8283 711 8
une surface de contact qui entre en contact avec une surface a contact surface which comes into contact with a surface
d'arret du corps des que la broche est entierement sortie. body stop as soon as the spindle is fully extended.
Ainsi, lorsque la surface de contact atteint la surface d'arret, le deplacement en translation du second ensemble est bloque. Ceci a pour effet de limiter la sortie du pilote et de Thus, when the contact surface reaches the stop surface, the displacement in translation of the second assembly is blocked. This has the effect of limiting the pilot output and
marquer le passage de la premiere etape a la seconde etape. mark the transition from the first stage to the second stage.
Avantageusement, chaque griffe de serrage est montee mobile en Advantageously, each clamping claw is mounted movable in
rotation autour diun axe porte par le pilote. rotation around an axis carried by the pilot.
Ainsi, chaque griffe fait saillie hors du pilote par un mouvement de pivotement. L' axe de rotation peut avantageusement etre utilise comme surface de contact venant en contact avec une paroi interieure du corps pour limiter la sortie du pilote Thus, each claw protrudes from the pilot by a pivoting movement. The axis of rotation can advantageously be used as a contact surface coming into contact with an interior wall of the body to limit the exit of the pilot.
hors du corps.out of the body.
Chaque griffe de serrage peut etre actionnee par des moyens Each clamping claw can be operated by means
independents des moyens d'actionnement de la sortie du pilote. independent of the means of actuation of the pilot output.
Toutefois, dans une realisation avantageuse, l'actionneur peut servir a la fois pour provoquer la sortie du pilote hors du corps au cours de la premiere etape, puis lt extraction de la griffe hors du pilote dans la seconde etape. Ainsi, dans une realisation particuliere, la griffe de serrage comporte une came et le premier ensemble porte un doigt de came, le doigt de came se deplacant sur la came lorsque le second ensemble se deplace par rapport au premier ensemble, ce qui provoque le passage de la griffe de serrage de la position escamotee a la However, in an advantageous embodiment, the actuator can be used both to cause the pilot to exit from the body during the first stage, then the extraction of the claw from the pilot in the second stage. Thus, in a particular embodiment, the clamping claw comprises a cam and the first assembly carries a cam finger, the cam finger moving on the cam when the second assembly moves relative to the first assembly, which causes passage of the clamp from the retracted position to the
position de serrage.clamping position.

Sur la Figure 1, la tete de bridage conforme a l' invention comprend un etage mecanique 12 et un etage de puissance 14, ici un etage electrique. Ces deux etages vent assembles entre eux de maniere demontable. L'etage mecanique 12 comporte un corps 16 de forme generale cylindrique comportant un alesage 18 ouvert a ses deux extremites, dans laquel est montee une douille 19. A sa partie superieure, le corps 18 est ferme par un capuchon 20. La face superieure 21 du capuchon est perforce par un alesage 22 dans lequel est introduit un epaulement 23 d'un disque plat 24 comportant un trou central 26. La face plane 27 du disque 24 constitue une face de reference pour le In FIG. 1, the clamping head according to the invention comprises a mechanical stage 12 and a power stage 14, here an electrical stage. These two stages are assembled together in a demountable manner. The mechanical stage 12 comprises a body 16 of generally cylindrical shape comprising a bore 18 open at its two ends, in which a sleeve 19 is mounted. At its upper part, the body 18 is closed by a cap 20. The upper face 21 of the cap is perforated by a bore 22 into which is introduced a shoulder 23 of a flat disc 24 having a central hole 26. The flat face 27 of the disc 24 constitutes a reference face for the

Un corps rotatif, designe dans son ensemble par la reference generale 30, est monte tournant a la partie inferieure du corps 16, par exemple au moyen de paliers a billes 32. Le corps 30 comporte une mollette dentranement 34 dans laquelle vent formes des trous 36 permettant diengager un outil dactionnement. La partie inferieure du corps 16 comporte un orifice 38 permettant l'accouplement de ltetage mecanique 12 avec l'etage de puissance 14. A sa partie superieure, le corps A rotary body, generally designated by the general reference 30, is mounted to rotate at the lower part of the body 16, for example by means of ball bearings 32. The body 30 comprises a drive wheel 34 in which wind forms holes 36 allowing to design an actuation tool. The lower part of the body 16 has an orifice 38 allowing the coupling of the mechanical stage 12 with the power stage 14. At its upper part, the body
16 comporte une vis 40.16 has a screw 40.
Un premier ensemble mobile, designe par la reference generale 42, est loge dans l'alesage 18 du corps 16. Ce premier ensemble est constitue dun ecrou 43 et d'une bague 44 solidaire de l'ecrou 43. L'ecrou 43 est guide en translation dans le corps 16 et il est bloque en rotation. Il comporte un alesage filete A first movable assembly, designated by the general reference 42, is housed in the bore 18 of the body 16. This first assembly consists of a nut 43 and a ring 44 secured to the nut 43. The nut 43 is guided in translation in the body 16 and it is blocked in rotation. It has a threaded bore
283711 8283 711 8
46 qui coopere avec la vis 40. Il comporte une partie evidee 48 dans laquelle l'extremite superieure de la vis 40 est logee. Un ressort en spirale 50 entoure la vis 40 et repose dans un logement 52 prevu dans le fond de l'evidement 48. L'ensemble mobile 52 est mobile en translation par rapport au corps 16. Le second ensemble mobile designe par la reference generale 54 46 which cooperates with the screw 40. It has a hollow part 48 in which the upper end of the screw 40 is housed. A spiral spring 50 surrounds the screw 40 and rests in a housing 52 provided in the bottom of the recess 48. The movable assembly 52 is movable in translation relative to the body 16. The second movable assembly designated by the general reference 54
est constitue essentiellement d'un pilote 56 et de griffes 58. consists essentially of a pilot 56 and claws 58.
En effet, bien que l' invention puisse comporter une griffe de serrage unique, elle peut egalement comporter plusieurs griffes, par exemple deux, comme dans l'exemple decrit sur les Indeed, although the invention may include a single clamping claw, it may also include several claws, for example two, as in the example described on the
Figures 1 a 4, voire davantage, par exemple trots ou quatre. Figures 1 to 4, or even more, for example trots or four.
Toutefois, dans un souci de clarte de la figure, une seule griffe 58 a ete representee sur les Figures 1 a 3, tandis que However, for the sake of clarity of the figure, a single claw 58 has been shown in Figures 1 to 3, while
deux griffes vent representees sur la Figure 4. two wind claws shown in Figure 4.
Le pilote 56 comporte une tete tronconique 60 arrondie a sa partie superieure destinee a penetrer dans le trou calibre de centrage de la piece a centrer et a serrer (non representee sur les Figures 1 a 3). Le pilote 56 comporte egalement un The pilot 56 comprises a tapered head 60 rounded at its upper part intended to penetrate into the calibrated centering hole of the part to be centered and to be clamped (not shown in Figures 1 to 3). Pilot 56 also includes a
evidement 62 destine a loger les deux griffes de serrage 58. recess 62 intended to accommodate the two clamping claws 58.
Ces derrieres vent montees pivotantes sur le pilote 56 autour dun axe horizontal 64. Les griffes 58 ont des extremites recourbees en forme de bee. A leur partie inferieure, les deux griffes 58 comportent une partie recourbee 66, sensiblement horizontale dans la position des griffes representee sur la Figure 1. Un profil de came 68 est forme dans la partie recourbee 66. Un doigt de came 70 solidaire de la bague 44 faisant partie du premier ensemble mobile 42 est engage dans le These rear windshields pivotally mounted on the pilot 56 around a horizontal axis 64. The claws 58 have curved ends in the shape of a bee. At their lower part, the two claws 58 have a curved part 66, substantially horizontal in the position of the claws shown in Figure 1. A cam profile 68 is formed in the curved part 66. A cam finger 70 integral with the ring 44 being part of the first mobile assembly 42 is engaged in the
profil de came 68.cam profile 68.
A sa partie inferieure, le pilote 56 est solidaire d'une collerette 57 montee coulissante dans l'evidement 48 de l'ecrou 43. La collerette 57 est sollicitee verticalement vers le haut par le ressort helicoidal 50 qui prend appui sur sa face inferieure. Ainsi, en l' absence de sollicitation contraire, la collerette 57 est plaquee contre un epaulement de la bague 44 At its lower part, the pilot 56 is secured to a flange 57 slidably mounted in the recess 48 of the nut 43. The flange 57 is urged vertically upwards by the helical spring 50 which bears on its lower face. Thus, in the absence of opposite stress, the flange 57 is pressed against a shoulder of the ring 44

L'etage de puissance 14 comporte un botier 80 de forme generale parallelepipedique ayant deux faces principales 82 et une face inferieure 84. Cette derriere est traversee par un cable electrique 86 termine par une fiche de connexion 88. La fiche 88 est. par exemple, un connecteur a la norme M23. A sa partie superieure, le boltier 80 comporte une face ouverte 90 susceptible detre adaptee et fixee de facon etanche et amovible sur l'etage mecanique 12. Le botier 82 est avantageusement realise en un materiau du meme type que le corps de l'etage mecanique 12, par exemple en polyamide charge The power stage 14 comprises a box 80 of generally parallelepiped shape having two main faces 82 and a lower face 84. This rear is crossed by an electric cable 86 terminated by a connection plug 88. The plug 88 is. for example, a connector has the M23 standard. At its upper part, the bolt case 80 has an open face 90 capable of being adapted and fixed in a sealed and removable manner on the mechanical stage 12. The case 82 is advantageously made of a material of the same type as the body of the mechanical stage 12, for example in polyamide filler
de fibres de verre.glass fibers.
Le botier 82 loge interieurement un actionneur rotatif 92. Cet actionneur peut etre pneumatique, mais il est de preference constitue par un moteur electrique ayant un axe de sortie 94 coaxial a l'axe general de la tete de serrage. Le moteur 92 est de preference un moteur du type "sans balai" alimente en The housing 82 internally houses a rotary actuator 92. This actuator can be pneumatic, but it is preferably constituted by an electric motor having an output axis 94 coaxial with the general axis of the clamping head. The motor 92 is preferably a motor of the "brushless" type supplied with
courant continu et en basse tension, typiquement sous 24 volts. direct current and low voltage, typically at 24 volts.
Ce moteur est pilote selon une loi choisie par l'intermediaire de moyens de commande 96 qui peuvent etre situes a l'interieur de l'etage de puissance 14, mais qui peuvent etre egalement This motor is piloted according to a law chosen by means of control means 96 which can be located inside the power stage 14, but which can also be
exterieurs a ce botier.outside this case.
Un accouplement demontable, du type a liaison elastique, est prevu entre l'axe de sortie 94 du moteur 92 et le corps rotatif 30. La rondelle elastique 100 comporte une configuration specifique, non circulaire. Dans ltexemple, elle comporte quatre lobes peripheriques decales a 90 les uns des autres A demountable coupling, of the elastic connection type, is provided between the output axis 94 of the motor 92 and the rotary body 30. The elastic washer 100 has a specific configuration, not circular. In the example, it has four peripheral lobes offset 90 from each other
(non representes) et ayant chacun sensiblement une forme semi- (not shown) and each having substantially a semi-shaped
circulaire. L'evidement 38 definit un logement de forme conjuguee destine a recevoir la rondelle elastique 100. On procure ainsi un accouplement rapide, de nature elastique, qui permet d' assurer automatiquement une liaison en rotation entre l'etage mecanique 12 et letage de puissance 14 lorsqu'ils vent circular. The recess 38 defines a housing of combined shape intended to receive the elastic washer 100. This provides a quick coupling, of elastic nature, which automatically ensures a rotational connection between the mechanical stage 12 and power letter 14 when they wind
283711 8283 711 8
mutuellement assembles. La rondelle elastique 100 est formee de preference dun materiau elastique semi-rigide. A ce titre, il est avantageux d'utiliser un materiau choisi parmi les polyamides et, en particulier, le materiau connu sous la denomination Ertalon (marque deposee). Ainsi, l'interchangeabilite de l'un ou l'autre des etages mecaniques 12 et de puissance 14 de la tete de bridage est grandement facilitee. Les deux etages vent prevus pour un fonctionnement a vie, et en cas de defaillance de l'un d'eux, il suffit simplement de le demonter pour le jeter et le remplacer par un etage neuf. Ceci permet de minimiser les temps d'immobilisation lors des operations de remplacement. Ceci est particulierement avantageux dans le cas d'une chane d'assemblage de vehicules automobiles qu'il n'est pas possible mutually assembled. The elastic washer 100 is preferably formed from a semi-rigid elastic material. As such, it is advantageous to use a material chosen from polyamides and, in particular, the material known under the name Ertalon (registered trademark). Thus, the interchangeability of one or other of the mechanical stages 12 and of power 14 of the clamping head is greatly facilitated. The two stages are provided for lifetime operation, and in the event of failure of one of them, it is sufficient to dismantle it to discard it and replace it with a new stage. This minimizes downtime during replacement operations. This is particularly advantageous in the case of a motor vehicle assembly line that it is not possible
d'arreter pour remplacer un equipement defectueux. to stop to replace defective equipment.
De ce fait, les operations de maintenance vent reduites et, pour cela, on utilisera de preference un etage mecanique Therefore, the maintenance operations are reduced wind and, for this, we will preferably use a mechanical floor
graisse a vie et non demontable.grease for life and not removable.
Sur la Figure 1, le pilote 56 a ete represente en position rentree. Dans cette position, la tete 60 du pilote ne fait pas In Figure 1, the pilot 56 has been shown in the retracted position. In this position, the pilot's head 60 does not

Les deux griffes de serrage 58 vent entierement retractees dans le logement 62. Leur extremite ne fait pas saillie au-dela du diametre exterieur du pilote 56, de telle sorte que ce dernier The two clamping claws 58 are fully retracted into the housing 62. Their ends do not protrude beyond the outside diameter of the pilot 56, so that the latter
peut traverser le trou 26 du disque 24. can pass through hole 26 of disc 24.
Dans cette position rentree representee sur la Figure 1, le premier ensemble mobile 42 est rentre au maximum dans l'alesage 18. La collerette 57 est plaquee contre un epaulement inferieur de la bague 44 solidaire de ltecrou 43. Le ressort helicoidal In this retracted position shown in Figure 1, the first movable assembly 42 is maximum in the bore 18. The flange 57 is pressed against a lower shoulder of the ring 44 secured to the nut 43. The helical spring

Lorsque le corps rotatif 30 est entrane en rotation par le moteur 92, la vis 40 deplace ltecrou 43 en translation vers le When the rotary body 30 is rotated by the motor 92, the screw 40 moves the nut 43 in translation towards the
283711 8283 711 8
haut. Le premier ensemble mobile 42 et le second ensemble mobile 54 se deplacent d'un bloc, ce qui provoque la sortie du pilote 56 et sa penetration dans le trou de centrage de la ou des pieces a centrer et a serrer (non representees), comme montre par la figure 2. Durant cette etape du mouvement, la collerette 57 reste plaquee contre la bague 44 par le ressort 50. L'axe transversal 64 des griffes de serrage 58 fait saillie de part et dautre du diametre exterieur du pilote 56. Ainsi, lorsque le premier ensemble mobile 42, et par consequent le second ensemble mobile 54 porte par le premier, se vent deplaces d'une distance d egale a la distance entre la partie superieure du diametre de l'axe transversal 64 et une surface de butee (non representee) prevue dans le disque 24 ou la face superieure du capuchon 20, le second ensemble mobile 54 est bloque en translation. La rotation du corps rotatif 30 et par consequent de la vis 40 se poursuivant, ltecrou 43 pour-quit son high. The first movable assembly 42 and the second movable assembly 54 move in one block, which causes the pilot 56 to exit and to penetrate into the centering hole of the piece or pieces to be centered and to be tightened (not shown), as shown in FIG. 2. During this stage of the movement, the flange 57 remains pressed against the ring 44 by the spring 50. The transverse axis 64 of the clamping claws 58 projects on either side of the outside diameter of the pilot 56. Thus , when the first mobile assembly 42, and consequently the second mobile assembly 54 carried by the first, is displaced by a distance equal to the distance between the upper part of the diameter of the transverse axis 64 and a stop surface (not shown) provided in the disc 24 or the upper face of the cap 20, the second movable assembly 54 is blocked in translation. The rotation of the rotary body 30 and consequently of the screw 40 continuing, the nut 43 for its quit

Toutefois, etant donne que le second ensemble mobile 54 est bloque contre la paroi superieure du corps, un deplacement relatif du premier et du second ensemble se produit. Plus precisement, la collerette 57 penetre a l'interieur de l'evidement 48, comme on peut le voir sur la Figure 3. La collerette 57 cesse detre plaquee contre la bague 44 et un jeu de plus en plus grand apparat entre la collerette 57 et la bague 54, ce qui provoque simultanement la compression du ressort helicodal 50. Dans le meme temps, le doigt de came 70 porte par la bague 44 provoque un mouvement de pivotement des griffes 58 autour de l'axe 64. Ce mouvement de pivotement a pour effet de faire sortir les deux extremites des griffes de However, since the second movable assembly 54 is blocked against the upper wall of the body, a relative displacement of the first and of the second assembly occurs. More precisely, the collar 57 penetrates inside the recess 48, as can be seen in FIG. 3. The collar 57 ceases to be pressed against the ring 44 and an increasing play appears between the collar 57 and the ring 54, which simultaneously causes the compression of the helical spring 50. At the same time, the cam finger 70 carried by the ring 44 causes a pivoting movement of the claws 58 around the axis 64. This pivoting movement has the effect of bringing out the two ends of the claws of

Les griffes 58 passent ainsi de la position escamotee representee sur les Figures 1 et 2 a la position de serrage representee sur la Figure 3. Dans cette position, ltextremite The claws 58 thus pass from the retracted position shown in Figures 1 and 2 to the clamping position shown in Figure 3. In this position, the end

On se refere maintenant a la Figure 4 montrant une piece P pourvue d'un trou calibre de centrage qui est traverse par la tete 60 du pilote. La piece P est interposee entre les extremites respectives 59 des griffes 58 et la face de reference 27 du disque 24 et elle est ainsi maintenue serree We now refer to Figure 4 showing a part P provided with a calibrated centering hole which is crossed by the head 60 of the pilot. The part P is interposed between the respective ends 59 of the claws 58 and the reference face 27 of the disc 24 and it is thus held tight

On realise ainsi successivement le centrage, puis le serrage de Centering is then carried out successively, then the tightening of

Selon ['invention, il est possible de changer aisement le diametre du pilote 56 pour l' adapter a des trous de centrage de diametre different en fonction de la nature des pieces a centrer et a serrer. A cette fin, le premier et le second ensemble mobile constituent avec la douille 19 une cassette d'outillage interchangeable. Il est possible de retirer, en une seule operation, la douille 19 contenant le premier ensemble mobile et le second ensemble mobile apres avoir retire le capuchon 20. La cassette doutillage interchangeable est remplacee par une autre cassette comportant un pilote 56 de diametre plus petit ou plus grand en fonction des besoins. Bien entendu, il convient de changer egalement le disque 24 de manibre que le diametre interieur du trou de guidage 26 According to the invention, it is possible to easily change the diameter of the pilot 56 to adapt it to centering holes of different diameter depending on the nature of the parts to be centered and to be tightened. To this end, the first and the second mobile assembly constitute with the sleeve 19 an interchangeable tool cassette. It is possible to remove, in a single operation, the sleeve 19 containing the first movable assembly and the second movable assembly after having removed the cap 20. The interchangeable tooling cassette is replaced by another cassette comprising a pilot 56 of smaller diameter or larger as needed. Of course, it is also necessary to change the disc 24 so that the inside diameter of the guide hole 26
corresponde au diametre exterieur du pilote 56. corresponds to the outside diameter of the pilot 56.
La mollette 34 prevue sur le corps rotatif permet un actionnement manuel de la t8te de bridage en cas d' incident de fonctionnement, et notamment en cas de panne de letage de The wheel 34 provided on the rotary body allows manual actuation of the clamping head in the event of an operating incident, and in particular in the event of failure of the
puissance 14.power 14.
On a represente sur la Figure 5 un exemple des moyens de commande de l'actionneur rotatif 92. Les moyens de commande 96 An example of the control means of the rotary actuator 92 is shown in FIG. 5. The control means 96
vent realises sous la forme d'une carte electronique, c'est-a- wind realized in the form of an electronic card, that is to
dire d'un circuit electronique. Dans l'exemple de realisation say of an electronic circuit. In the example of realization

represente, cette carte est destinee a etre inseree dans le shown, this card is intended to be inserted in the
boltier 80, comme decrit precedemment. boltier 80, as described above.
La carte 96 comprend une regulation 120 qui controle le moteur 92 au travers d'un pilote 122. Cette regulation est alimentee electriquement au travers d'un raccord 124 ayant deux bornes susceptibles d'etre reliees respectivement au pole positif (+V) et au pole negatif (-V) d'une source de courant a basse tension. Des fils electriques 126 alimentent egalement le pilote. La regulation 120 peut comporter differents moyens de parametrage. Dans ltexemple, elle comporte des moyens de parametrage MP1 pour parametrer ['effort de serrage exerce par les griffes de serrage 58, des moyens de parametrage MP2 pour parametrer l' angle d'ouverture des griffes de serrage entre la position retractee et la position de serrage et des moyens de parametrage MP3 pour parametrer une loi de mouvement des The card 96 includes a regulation 120 which controls the motor 92 through a pilot 122. This regulation is supplied electrically through a connector 124 having two terminals capable of being connected respectively to the positive pole (+ V) and to the negative pole (-V) of a low voltage current source. Electric wires 126 also supply the pilot. Regulation 120 can include different means of parameterization. In the example, it includes setting means MP1 for setting the clamping force exerted by the clamping claws 58, setting means MP2 for setting the opening angle of the clamping claws between the retracted position and the position of tightening and MP3 setting means to set a law of motion of
griffes de serrage 58.clamping claws 58.
Les moyens de parametrage MP1 peuvent, a titre d'exemple, parametrer l 'effort de serrage a une valeur comprise entre 40 The setting means MP1 can, for example, set the clamping force to a value between 40
et 200 daN.and 200 daN.
Le dispositif est parametrable par un ordinateur. I1 peut comporter un codage angulaire. On peut gerer la position des bras des griffes de serrage et serrer des soles depaisseur differente. La gestion electronique permet de supprimer le "presence piece". En effet, si l'extremite des griffes de serrage ne rencontre pas de tole pendant la fermeture, le moteur 92 S ' arrete et declenche, grace a lelectronique The device can be configured by a computer. I1 may include angular coding. You can manage the position of the arms of the clamping claws and clamp different thicknesses. Electronic management eliminates the "presence piece". Indeed, if the end of the clamping claws does not meet any sheet during closing, the 92 motor stops and starts, thanks to the electronics

La fixation du systeme est conforme a la norme CNOMO. L'etage de puissance 14 est interchangeable avec un autre, par exemple The fixing of the system conforms to the CNOMO standard. The power stage 14 is interchangeable with another, for example
avec un etage de puissance pneumatique. with a pneumatic power stage.
La tete de serrage conforme a l' invention presente ainsi de nombreux avantages. Wile est constituee de deux soul-ensembles The clamping head according to the invention thus has numerous advantages. Wile is made up of two souls

Par ailleurs, ces deux soul-ensembles vent concus pour avoir une longue duree de vie et ils vent jetables en cas de mauvais fonctionnement. I1 n'est done pas necessaire de les ouvrir et Furthermore, these two soul-wind assemblies are designed to have a long lifespan and they are disposable in the event of malfunction. There is therefore no need to open them and
