Description

La présente invention concerne un dispositif de réglage de la position d'une levée montée sur une ancre d'un échappement d'un mouvement d'horlogerie en vue du réglage de la pénétration de la levée dans la denture de la roue d'échappement, et plus particulièrement un dispositif permettant un réglage avec une précision de l'ordre du micron de cette pénétration.The present invention relates to a device for adjusting the position of a lift mounted on an anchor an escapement from a watch movement for the purpose of adjustment of the penetration of the lift in the toothing of the escape wheel, and more particularly a device allowing adjustment with precision of the micron order of this penetration.

En horlogerie, on désigne par échappement le mécanisme placé entre le rouage d'un mouvement d'horlogerie et son régulateur, par exemple le balancier du mouvement de montre, cet échappement ayant pour fonction d'entretenir les oscillations du balancier.In watchmaking, we refer to the escapement as mechanism placed between the cogs of a movement and its regulator, for example the pendulum of the watch movement, this escapement having for function of maintaining the oscillations of the balance wheel.

En se référant à la figure 1, on va brièvement décrire un échappement 1 de montre à ancre classique. L'échappement 1 comprend une roue d'échappement 2, une ancre 4, un grand plateau 6 portant une cheville 8 et un petit plateau 10 muni d'une encoche 11, portés par l'axe du balancier 12. L'ancre comprend deux levées telles que 14 coopérant avec la roue 2 ainsi qu'une baguette 16 se terminant par une fourchette 17 à trois dents coopérant avec les grands et petits plateaux 6 et 10 respectivement. Ces levées 14 sont solidarisées chacune dans un logement 18 approprié prévu dans les branches telles que 19 de l'ancre 4 par exemple au moyen d'une gomme-laque (non représentée). La fourchette 17 comprend deux dents extérieures telles que 20 qui coopèrent avec la cheville 8 tandis que la dent intérieure ou dard 22 coopère avec le petit plateau 10 et empêche le renversement intempestif de l'ancre 4 durant l'oscillation supplémentaire du balancier (non représenté). Les mouvements de l'ancre 4 sont limités par des goupilles ou butées telles que 24 sur lesquelles la baguette 16 vient buter. Dans la position de repos, la baguette 16 appuie sur une des deux goupilles 24 de limitation. A ce moment, une dent 2d de la roue d'échappement 2 est appuyée contre l'une des levées 14 comme cela est représenté à la figure 1. La dent intérieure 22 de la fourchette 17 est dégagée de l'encoche 11 de sorte que le balancier est libéré et parcourt son amplitude dans le sens antihoraire S jusqu'à ce que son énergie soit épuisée. Le balancier reprend alors le sens horaire pour dégager la levée 14 de la dent 2d. Après l'impulsion donnée sur la levée 14 par la dent 2d, l'ancre parcourt à vide une petite distance, dite chemin perdu, jusqu'au moment où la baguette 16 vient buter contre la goupille 24. Le balancier parcourt alors son amplitude et revient jusqu'à ce que la cheville 8 du grand plateau 6 entraíne la fourchette 17 qui déclenche l'impulsion suivante. Ce chemin perdu est un moyen de s'assurer que toutes les dents de la roue d'échappement 2 puissent passer. Or, la longueur de ce chemin perdu est fonction de la pénétration P de la dent de la roue d'échappement 2 sur le plan de repos 27 de la levée 14, cette pénétration devant être à la fois suffisante pour éviter la libération intempestive de la roue d'échappement 2, par exemple lors d'un choc, et suffisamment faible pour garantir une libération des dents de la roue d'échappement 2 en toute circonstance de fonctionnement afin d'obtenir un échappement 1 ayant un rendement optimal.Referring to Figure 1, we will briefly describe an escapement 1 of a conventional anchor watch. The exhaust 1 comprises an escape wheel 2, a anchor 4, a large plate 6 carrying an ankle 8 and a small plate 10 provided with a notch 11, carried by the axis balance 12. The anchor includes two lifts such that 14 cooperating with the wheel 2 and a rod 16 is ending with a fork 17 with three cooperating teeth with large and small plates 6 and 10 respectively. These lifts 14 are each secured in a suitable housing 18 provided in the branches such as 19 of anchor 4 for example using a shellac (not shown). Fork 17 includes two teeth external such as 20 which cooperate with the pin 8 while the inner tooth or stinger 22 cooperates with the small tray 10 and prevents accidental spillage of anchor 4 during the additional swing of the pendulum (not shown). The movements of the anchor 4 are limited by pins or stops such as 24 on which the rod 16 abuts. In the rest position, the rod 16 presses on one of the two pins 24 of limitation. At this time, a 2d tooth of the wheel exhaust 2 is pressed against one of the lifts 14 as shown in Figure 1. The tooth inside 22 of the fork 17 is released from the notch 11 so that the pendulum is released and runs through its counterclockwise amplitude S until its energy is exhausted. The pendulum then resumes the direction schedule to clear the lift 14 of tooth 2d. After the impulse given on lift 14 by tooth 2d, the anchor travels empty a short distance, called the lost path, until the rod 16 comes up against the pin 24. The pendulum then traverses its amplitude and returns until the pin 8 of the large plate 6 drives the fork 17 which triggers the pulse next. This lost path is a way of ensuring that all the teeth of the escape wheel 2 can pass. However, the length of this lost path is a function of the penetration P of the tooth of the escape wheel 2 on the rest plane 27 of the lift 14, this penetration should be both sufficient to avoid release accidental escape wheel 2, for example during shock, and low enough to guarantee freeing the teeth of the escape wheel 2 completely operating circumstance in order to get a exhaust 1 having optimal efficiency.

La société Animex établie à Bienne, Suisse, propose un appareil pour réaliser le réglage de cette pénétration P. Cet appareil comprend un posage sur lequel l'ancre terminée est positionnée et serrée. Le posage est alors placé sur un réchaud électrique permettant d'amener la gomme-laque pour la solidarisation de la levée sur l'ancre à sa température de ramollissement, généralement 90°C. L'opérateur agit alors sur la levée en la poussant dans un sens ou dans l'autre à l'aide d'une pointe pour apporter la correction souhaitée, la valeur de la correction ayant été préalablement déterminée par une méthode de mesure appropriée. Le déplacement de la levée engendre le déplacement de la touche d'un comparateur qui est en contact avec la levée, et la valeur du réglage est contrôlée par le déplacement d'une aiguille sur le cadran d'un comparateur.Animex, established in Bienne, Switzerland, offers a device for adjusting this penetration P. This device includes a setting on which the anchor finished is positioned and tightened. The laying is then placed on an electric stove to bring the shellac for securing the lift on the anchor at its softening temperature, generally 90 ° C. The operator then acts on the lift by pushing it into a either way using a tip to bring the desired correction, the value of the correction having been previously determined by a measurement method appropriate. The movement of the lift generates the displacement of the key of a comparator which is in contact with the lift, and the setting value is controlled by the movement of a hand on the dial a comparator.

Cet appareil présente toutefois de nombreux inconvénients. En effet, à chaque réglage, l'opérateur risque d'endommager irrémédiablement les levées avec la pointe utilisée, les levées étant réalisées en un matériau très fragile. Ces levées étant des éléments fonctionnels de l'échappement, on comprend aisément qu'un endommagement de celles-ci n'est pas acceptable.However, this device has many disadvantages. Indeed, at each adjustment, the operator risk of irreparably damaging the levees with the point used, the lifts being made of a material very fragile. These levees being functional elements of the exhaust, it is easy to understand that damage of these is not acceptable.

En outre, au cours du réglage, par exemple lorsque l'opérateur agit sur la levée, il risque de désaligner la levée par rapport à son logement, ce qui conduit à une modification de la géométrie du système d'échappement et, par conséquent, à une correction de la pénétration insatisfaisante. Il est donc nécessaire dans ce cas d'effectuer un nouveau réglage, ce qui engendre des coûts supplémentaires et augmente le prix de revient du mouvement.In addition, during adjustment, for example when the operator acts on the lift, he risks misaligning the lifted from its housing, which leads to a modification of the geometry of the exhaust system and, therefore, to a correction of penetration unsatisfactory. It is therefore necessary in this case to make a new adjustment, which generates costs additional and increases the cost price of movement.

L'invention a donc pour but principal de remédier aux inconvénients de l'art antérieur susmentionnés en fournissant un dispositif de réglage de la position d'une levée montée sur une ancre qui soit simple, précis, et qui ne risque pas d'endommager les levées, permettant ainsi de faciliter l'optimisation du rendement de l'échappement, c'est-à-dire l'augmentation de l'amplitude de l'organe régulateur auquel il est associé.The main aim of the invention is therefore to remedy the disadvantages of the aforementioned prior art in providing a device for adjusting the position of a lift mounted on an anchor which is simple, precise, and which does not risk damaging the lifts, thus allowing facilitate optimization of exhaust efficiency, that is to say the increase in the amplitude of the organ regulator with which it is associated.

A cet effet, l'invention a pour objet un dispositif de réglage de la position d'une levée montée sur une ancre en vue du réglage de sa pénétration dans la denture d'une roue d'échappement d'un mouvement d'horlogerie, le dispositif étant caractérisé en ce qu'il comprend un bâti fixe associé à un chariot mobile en translation selon un axe, des moyens de commande du déplacement du chariot, des moyens de mesure du déplacement du chariot par rapport au bâti, des moyens de fixation de l'ancre sur le bâti ou le chariot et des moyens de fixation de la levée respectivement sur le chariot ou le bâti.To this end, the invention relates to a device for adjusting the position of a lift mounted on an anchor for adjusting its penetration into the teeth of a escapement wheel of a watch movement, the device being characterized in that it comprises a frame fixed associated with a mobile carriage in translation according to a axis, means for controlling the movement of the carriage, means for measuring the movement of the carriage relative to the frame, means for fixing the anchor to the frame or the carriage and means for fixing the lift respectively on the carriage or the frame.

Grâce à ces caractéristiques, il est possible de maítriser, par la commande du déplacement du chariot par rapport au bâti en liaison avec les moyens de mesure, le déplacement de la levée par rapport à l'ancre et donc la correction souhaitée avec une très grande précision, sans risquer d'endommager la levée avec des outils comme cela est le cas dans l'art antérieur. Ce dispositif permet également de garantir un déplacement de la levée selon son axe longitudinal et, par conséquent, de garantir une conservation de la géométrie de l'échappement lors du réglage.Thanks to these features, it is possible to control, by controlling the movement of the carriage by relation to the frame in connection with the measuring means, the displacement of the lift relative to the anchor and therefore the correction desired with very high precision, without risk damaging the lift with tools like this is the case in the prior art. This device allows also to guarantee a displacement of the lift according to its longitudinal axis and, therefore, to guarantee a conservation of the exhaust geometry during setting.

Selon un mode de réalisation préféré de l'invention, le dispositif comprend en outre des moyens de chauffage, ces moyens de chauffage étant préférentiellement fixés sur l'élément bâti ou chariot portant l'ancre.According to a preferred embodiment of the invention, the device also comprises heating means, these heating means being preferably fixed on the built element or carriage carrying the anchor.

Ces moyens de chauffage permettent d'amener aisément la gomme-laque servant à la solidarisation de la levée à sa température de ramollissement, et facilitent ainsi le déplacement de la levée dans son logement et donc le réglage souhaité.These heating means make it easy to bring shellac used to secure the lifting to its softening temperature, and thus facilitate displacement of the lift in its housing and therefore the desired setting.

Selon une caractéristique avantageuse, les moyens de fixation de l'ancre sont des moyens de serrage portés par le chariot et comprennent un levier articulé sur le chariot, le levier étant bloqué en position de serrage au moyen d'une vis.According to an advantageous characteristic, the means of anchor fixing are clamping means carried by the carriage and include a lever articulated on the carriage, the lever being locked in the clamping position at by means of a screw.

L'utilisation d'un levier articulé pour le serrage permet de dégager l'espace situé au voisinage de l'emplacement du chariot destiné à la réception de l'ancre, et à sa mise en place en position de réglage. D'autre part, l'utilisation du levier présente l'avantage de n'avoir aucune influence sur la position de la levée au serrage comme au desserrage lorsque celle-ci est maintenue par les moyens de serrage portés par le bâti.The use of an articulated lever for tightening clears the space in the vicinity of the location of the cart for receiving the anchor, and when it is placed in the adjustment position. On the other hand, the use of leverage has the advantage to have no influence on the position of the lift at tightening as when loosening it is maintained by the clamping means carried by the frame.

En se référant aux figures 2 à 4a,4b, on voit un dispositif selon l'invention, désigné dans son ensemble par la référence générale 30, pour le réglage de la position de la levée 14 montée sur l'ancre 4 en vue du réglage de la pénétration P (figure 1a) dans la denture de la roue d'échappement 2 d'un mouvement d'horlogerie classique.Referring to Figures 2 to 4a, 4b, we see a device according to the invention, designated as a whole by the general reference 30, for the adjustment of the position of the lift 14 mounted on the anchor 4 for the adjustment of the penetration P (figure 1a) in the teeth of the escapement wheel 2 of a clockwork movement classic.

The table carries on its movable upper part a plate 37 and is fixed to the frame 32 by its lower part, for example using screws. Such a measurement table is notably sold by OWIS under the reference MT 30. On will of course understand that other control means 36 manual or automatic can be considered. We will be able to in particular provide digital control means allowing the control of the movement of the table in function of a determined correction value entered via a keyboard.

Le dispositif 30 comprend en outre des moyens de mesure 38 permettant de mesurer le déplacement du bâti 32 par rapport au chariot 34, des moyens de fixation 40 de l'ancre 4 sur une surface de posage 42 du chariot 34, et des moyens de fixation 44 de la levée 14 sur le bâti 32. Dans l'exemple représenté, la surface de posage 42 est formée par la surface supérieure de la platine 37The device 30 further comprises means for measure 38 to measure the displacement of the frame 32 relative to the carriage 34, fixing means 40 of the anchor 4 on a setting surface 42 of the carriage 34, and means 44 for fixing the lift 14 to the frame 32. In the example shown, the laying surface 42 is formed by the upper surface of the plate 37

Les moyens de mesure 38 comprennent un comparateur analogique 45 ayant une précision de mesure égale au micromètre. Plus précisément, le comparateur 45 comprend une partie mobile 46 formée par une touche de palpage qui actionne l'aiguille se déplaçant au dessus du cadran gradué du comparateur 45, et une partie cylindrique fixe 48 solidaire du boítier du comparateur 45. La partie fixe 48 s'étend dans un perçage 50 parallèle à l'axe A, ménagé dans le bâti 32. Le perçage 50 débouche en regard d'une paroi 52 du chariot 34 avec laquelle la partie mobile 46 du comparateur 45 est en contact direct à tout moment. Un tel comparateur analogique 45 est vendu par la société CARY au Locle, Suisse, sous la référence MC 8-2.The measuring means 38 include a comparator analog 45 with measurement accuracy equal to micrometer. More specifically, the comparator 45 comprises a movable part 46 formed by a feeler touch which operates the hand moving above the dial graduated from comparator 45, and a fixed cylindrical part 48 secured to the comparator housing 45. The fixed part 48 extends in a bore 50 parallel to the axis A, formed in the frame 32. The bore 50 opens opposite a wall 52 of the carriage 34 with which the movable part 46 of comparator 45 is in direct contact at all times. A such analog comparator 45 is sold by the company CARY in Le Locle, Switzerland, under the reference MC 8-2.

Il va de soi que d'autres moyens de mesure 38 du déplacement du chariot 34 peuvent être envisagés. On pourra par exemple prévoir des moyens optiques utilisant l'analyse d'images vidéo, ou encore des moyens électroniques tels qu'un axe numérique.It goes without saying that other means 38 of measuring displacement of the carriage 34 can be envisaged. We could for example provide optical means using the analysis of video images, or even means electronic such as a digital axis.

Les moyens de fixation 40 de l'ancre 4 comprennent, selon un mode de réalisation préféré, un levier 54 articulé sur le chariot 34 et associé à des moyens de serrage 56. Le levier 54 est articulé à distance de la surface de posage 42 et comprend une extrémité libre 58 destinée à appuyer l'ancre 4 contre la surface de posage 42 dans une position de serrage des moyens de fixation 40.The fixing means 40 of the anchor 4 comprise, according to a preferred embodiment, a lever 54 articulated on the carriage 34 and associated with means of tightening 56. The lever 54 is articulated at a distance from the laying surface 42 and includes a free end 58 intended to support the anchor 4 against the setting surface 42 in a clamping position of the fixing means 40.

Dans l'exemple représenté, les moyens de serrage 56 comprennent une came 60 ménagée sur le levier 54 et disposée entre son point d'articulation et son extrémité libre 58. Cette came 60 qui présente la forme d'une demi-lune est actionnée par un bras en "L" 62 articulé par l'une de ses branches 62a sur le chariot 34. Une vis 64 traversant l'extrémité libre de l'autre branche 62b est en contact par son extrémité avec la surface de la came 60. La came 60 et le bras actionneur 62 sont configurés de sorte que lorsque le bras 62 atteint le point culminant de la came 60, l'extrémité libre 58 du levier 54 s'approche de la surface de posage 42. Ainsi, une rotation du bras actionneur 62 dans un plan perpendiculaire à la surface de posage 42, mais parallèle à l'axe A entraíne un abaissement du levier 54 en direction de ladite surface de posage 42, le serrage définitif étant réalisé à l'aide de la vis 64. Pour éviter un serrage trop important qui pourrait détériorer l'ancre 4, on pourra prévoir des moyens de limitation de la force de serrage de la vis 64, par exemple sous la forme d'une vis à couple réglable.In the example shown, the clamping means 56 comprise a cam 60 formed on the lever 54 and arranged between its articulation point and its end free 58. This cam 60 which has the shape of a half-moon is actuated by an L-shaped arm 62 articulated by one of its branches 62a on the carriage 34. A screw 64 crossing the free end of the other branch 62b is in contact at its end with the surface of the cam 60. Cam 60 and actuator arm 62 are configured to so that when arm 62 reaches the highest point of the cam 60, the free end 58 of the lever 54 approaches of the laying surface 42. Thus, a rotation of the arm actuator 62 in a plane perpendicular to the surface of laying 42, but parallel to the axis A results in a lowering of the lever 54 in the direction of said surface of fitting 42, the final tightening being carried out using screw 64. To avoid excessive tightening which could damage the anchor 4, we can provide means for limiting the tightening force of the screw 64, for example in the form of an adjustable torque screw.

Le levier 54 comprend à son extrémité libre 58 une fourche de serrage 66 à deux branches 66a, 66b qui serrent respectivement des portions de l'ancre 4 situées de part et d'autre de la levée 14.The lever 54 comprises at its free end 58 a clamping fork 66 with two arms 66a, 66b which tighten respectively portions of the anchor 4 located on the side and on the other side of levee 14.

On notera à ce propos que selon une variante de réalisation non représentée, l'écartement des branches 66a, 66b de la fourche de serrage 66 peut être réglable, par exemple à l'aide d'une vis engagée transversalement dans une des branches, poussant par une extrémité l'autre branche. Un tel réglage de cet écartement permettrait au dispositif 30 de s'adapter à des ancres 4 ayant des levées 14 de largeur quelconque.Note in this connection that according to a variant of not shown, branch spacing 66a, 66b of the clamping fork 66 can be adjustable, for example using a screw engaged transversely in one of the branches, pushing the other end plugged. Such adjustment of this spacing would allow the device 30 to adapt to anchors 4 having lifts 14 of any width.

Selon une autre caractéristique avantageuse de l'invention, le point d'articulation du levier 54 sur le chariot 34 est également réglable transversalement par rapport à la direction de déplacement dudit chariot 34, par exemple à l'aide d'un système vis-écrou (non représenté). En effet, le réglage de la position du point d'articulation du levier 54 permet d'obtenir une localisation optimale du point de serrage quelle que soit la géométrie de l'ancre 4 à régler.According to another advantageous characteristic of the invention, the point of articulation of the lever 54 on the carriage 34 is also adjustable transversely by relative to the direction of movement of said carriage 34, for example using a screw-nut system (not represented). Indeed, the adjustment of the position of the point of articulation of the lever 54 makes it possible to obtain a optimal location of the clamping point whatever the geometry of the anchor 4 to be adjusted.

On voit également sur la figure 2 que le dispositif 30 comprend des moyens de chauffage 68. Comme cela apparaítra plus clairement dans la suite de la description, ces moyens de chauffage 68 sont destinés à ramollir les moyens de solidarisation - par exemple une gomme-laque - des levées 14 dans leurs logements afin de faciliter leurs déplacements dans ce dernier et donc le réglage de la pénétration P.We also see in Figure 2 that the device 30 includes heating means 68. Like this will appear more clearly in the rest of the description, these heating means 68 are intended for soften the means of securing - for example a shellac - levees 14 in their homes to facilitate their movements in the latter and therefore the penetration adjustment P.

Dans l'exemple illustré, les moyens de chauffage 68 sont fixés sur le chariot 34 et comprennent un corps de chauffe 70 formé d'une résistance électrique reliée à une source de tension variable. Plus précisément, le corps de chauffe 70 est situé dans un logement de la platine 37 prévu à cet effet, ce logement étant ménagé de préférence le plus proche possible de la surface de posage 42 sur laquelle l'ancre 4 est serrée.In the example illustrated, the heating means 68 are fixed on the carriage 34 and include a body of heater 70 formed of an electrical resistance connected to a variable voltage source. Specifically, the body of heater 70 is located in a housing of the plate 37 provided for this purpose, this housing preferably being provided as close as possible to the laying surface 42 on which the anchor 4 is tightened.

Il va de soi que d'autre moyens de chauffage peuvent être envisagés. On pourra notamment prévoir des moyens de chauffage à faisceau laser ou à lumière infrarouge.It goes without saying that other means of heating can be considered. Means may in particular be provided for heating by laser beam or infrared light.

De même, bien qu'il soit avantageux de fixer les moyens de chauffage 68 sur l'élément qui porte l'ancre 4, en l'occurrence le chariot 34, il est également envisageable de les fixer sur le bâti 32.Likewise, although it is advantageous to fix the heating means 68 on the element carrying the anchor 4, in this case the carriage 34, it is also possible to fix them on the frame 32.

Les moyens de fixation 44 de la levée 14 comprennent une pince 72 fixée sur une surface supérieure 74 du bâti 32. Cette surface 74 est sensiblement coplanaire à la surface de posage 42 et comprend de préférence un dégagement 75 dans la région située au-dessous de la pince 72. La pince 72 comprend une mâchoire fixe 76 et une mâchoire mobile 78. Selon une caractéristique importante de l'invention, la mâchoire fixe 76 comprend une surface de serrage 80 qui s'étend parallèlement à l'axe de déplacement A et est prévue pour agir sur une face latérale 14a de la levée 14, la mâchoire mobile 78 agissant sur la face latérale opposée 14b de la levée 14.The means 44 for fixing the lift 14 comprise a clamp 72 fixed on an upper surface 74 of the frame 32. This surface 74 is substantially coplanar with the laying surface 42 and preferably comprises a clearance 75 in the area below the clamp 72. The clamp 72 includes a fixed jaw 76 and a movable jaw 78. According to an important characteristic of the invention, the fixed jaw 76 comprises a surface clamping 80 which extends parallel to the axis of displacement A and is intended to act on one side lateral 14a of the lift 14, the movable jaw 78 acting on the opposite side face 14b of the lift 14.

La mâchoire 78 est mobile en rotation dans le plan de l'ancre 4 autour d'un axe 82 et est commandée par un système à excentrique 84. La force de serrage des mâchoires 76 et 78 est donnée par des moyens à ressort 86 qui agissent sur la mâchoire mobile 78 et la rappellent vers sa position de fermeture représentée par exemple sur la figure 3. En agissant sur la raideur du ressort, on comprendra que la force de serrage de la pince 72 peut être aisément ajustée et limitée pour éviter tout risque d'endommagement de la levée 14 lors du serrage. L'excentrique 84 qui est commandé par un levier de serrage 88, ne sert donc qu'à agir sur la mâchoire mobile 78 pour ouvrir la pince 72.The jaw 78 is movable in rotation in the plane of anchor 4 around an axis 82 and is controlled by a eccentric system 84. The clamping force of the jaws 76 and 78 is given by spring means 86 which act on the movable jaw 78 and recall it towards its closed position represented for example on Figure 3. By acting on the stiffness of the spring, we will understand that the clamping force of the clamp 72 can be easily adjusted and limited to avoid any risk damage to the lift 14 during tightening. Eccentric 84 which is controlled by a clamping lever 88, therefore only serves to act on the movable jaw 78 to open clamp 72.

Il va de soi que d'autres moyens de fixation de l'ancre 4, respectivement de la levée 14, que ceux décrits ci-dessus peuvent être envisagés. On pourra par exemple prévoir des moyens de fixation pneumatiques ou électromagnétiques.It goes without saying that other means of fixing the anchor 4, respectively of the lift 14, than those described above can be considered. We could for example provide pneumatic fastening means or electromagnetic.

Aux figures 4a et 4b, on voit que le dispositif de réglage 30 est associé à des moyens optiques 90 de grossissement pour l'observation de la levée 14. Dans le mode de réalisation illustré, les moyens optiques 90 comprennent un microscope binoculaire monté à coulissement le long d'une colonne de support 92 encastrée dans un socle 94 portant également le dispositif 30.In FIGS. 4a and 4b, it can be seen that the device for adjustment 30 is associated with optical means 90 of magnification for observation of levee 14. In the illustrated embodiment, the optical means 90 include a sliding mounted binocular microscope along a support column 92 embedded in a base 94 also carrying the device 30.

Il va de soi que d'autres moyens optiques de grossissement que ceux décrits ci-dessus peuvent être envisagés. On pourra par exemple prévoir à la place du microscope binoculaire une caméra vidéo reliée à un écran de contrôle.It goes without saying that other optical means of magnification as those described above can be considered. We could for example provide instead of binocular microscope a video camera connected to a screen control.

Le fonctionnement du dispositif 30 va maintenant être décrit en faisant notamment référence aux figures 3, 4a et 4b.The operation of the device 30 will now be described with particular reference to Figures 3, 4a and 4b.

On commence tout d'abord par ouvrir les mâchoires 76, 78 de la pince 72 en agissant sur le levier de serrage 88 dans les sens de la flèche O (figure 2). On relève ensuite le levier 54 pour dégager la surface de posage 42 et la rendre accessible (levier 54 en pointillé à la figure 4). On aura bien entendu desserré la vis 64 et dégagé le bras 62 de la came 60 préalablement au relèvement du levier 54 (figure 4a). On procède alors à la mise en place de l'ancre 4 sur la surface de posage 42, en veillant à ce que le dard 22 se trouve dirigé du côté opposé à la platine 37 (vers le haut), tout en plaçant la levée 14 à régler entre les mâchoires 76 et 78 de la pince 72. On ferme alors la pince 72 en agissant sur le levier de serrage 88 dans le sens F de sorte que les mâchoires 76, 78 viennent serrer la levée sur ses faces latérales 14a, 14b. Au cours de la fermeture des mâchoires 76,78, la levée 14 s'aligne donc sur la surface de serrage 80 de la mâchoire fixe 76 et par voie de conséquence sur l'axe de déplacement A du chariot 34. Le levier 54 est alors rabattu de sorte que les branches 66a, 66b de la fourche de serrage 66 viennent à proximité des parties de l'ancre 4 situées de part et d'autre de la levée 14 en veillant à ne pas les toucher. Pour ce faire, on déplace le bras 62 dans le sens de la flèche F1 (figure 4). Au cours de ce déplacement, la vis 64 chemine le long de la came 60 jusqu'à atteindre le sommet de celle-ci. Le chariot 34 est alors déplacé en agissant sur la vis micrométrique 36 pour amener l'aiguille du comparateur 38 en regard d'un repère fixe telle que la graduation zéro. Le levier 54 est ensuite bloqué en position rabattue à l'aide de la vis 64. Le cas échéant l'écartement des branches 66a, 66b de la fourche de serrage 66 aura préalablement été ajusté pour éviter que ces branches viennent en contact avec la levée 14. On peut alors déplacer la levée 14 relativement à l'ancre 4 d'une valeur déterminée pour obtenir la valeur de pénétration P souhaitée, la valeur de déplacement étant directement lue sur le cadran du comparateur 38. Une fois le réglage effectué, les opérations de solidarisation de l'ancre 4 décrites ci-dessus sont effectuées en sens inverse. Préalablement à l'opération de déplacement du chariot 34 pour le réglage de la pénétration P, on aura de préférence enclencher les moyens de chauffage 68 pour ramollir suffisamment la gomme-laque afin d'autoriser un déplacement aisé de la levée 14 dans son logement 18 sans toutefois que la gomme-laque se détache du fond dudit logement 18. On comprendra bien entendu que les opérations qui viennent d'être décrites sont réalisées de préférence en observant l'ancre 4 au microscope.We start first by opening the jaws 76, 78 of the clamp 72 by acting on the clamping lever 88 in the direction of arrow O (figure 2). We then note the lever 54 to release the laying surface 42 and the make it accessible (lever 54 dotted in Figure 4). We will of course have loosened the screw 64 and released the arm 62 of the cam 60 before raising the lever 54 (Figure 4a). We then proceed with the establishment of the anchor 4 on the setting surface 42, taking care that that the sting 22 is directed on the side opposite the stage 37 (upwards), while placing the lift 14 to adjust between the jaws 76 and 78 of the clamp 72. We then closes the clamp 72 by acting on the lever clamping 88 in direction F so that the jaws 76, 78 clamp the lift on its lateral faces 14a, 14b. During the closing of the jaws 76,78, the lift 14 therefore aligns with the clamping surface 80 of the fixed jaw 76 and consequently on the axis of displacement A of the carriage 34. The lever 54 is then folded down so that the branches 66a, 66b of the fork clamp 66 come close to the parts of anchor 4 located on either side of levee 14 in being careful not to touch them. To do this, we move arm 62 in the direction of arrow F1 (FIG. 4). At during this movement, the screw 64 travels along the cam 60 until reaching the top thereof. The carriage 34 is then moved by acting on the screw micrometric 36 to bring the comparator needle 38 next to a fixed mark such as the zero graduation. The lever 54 is then locked in the folded position at using screw 64. If necessary, the spacing of the branches 66a, 66b of the clamping fork 66 aura previously adjusted to prevent these branches come into contact with levee 14. We can then move the lift 14 relative to the anchor 4 by one value determined to obtain the penetration value P desired, the displacement value being read directly on the dial of comparator 38. Once the setting carried out, the operations for securing the anchor 4 described above are performed in reverse. Before moving the carriage 34 for the adjustment of the penetration P, we will preferably have switch on the heating means 68 to soften enough shellac to allow a easy movement of the lift 14 in its housing 18 without however, shellac will come off the bottom of said shell housing 18. It will of course be understood that the operations which have just been described are preferably carried out observing anchor 4 under the microscope.

Avec le dispositif de réglage qui vient d'être décrit, il est désormais possible de régler la pénétration des levées d'échappement avec une précision de l'ordre du micron, et ce de façon reproductible et aisée, augmentant ainsi la vitesse des opérations d'achevage. Ce dispositif présente également l'avantage d'être utilisable pour la plupart des ancres courantes.With the adjustment device which has just been described, it is now possible to adjust the penetration exhaust lifts with an accuracy of the order of micron, reproducibly and easily, increasing thus the speed of the completion operations. These measures also has the advantage of being usable for most common anchors.
