L'invention concerne le domaine de la fabrication des composants d'horlogerie, et en particulier de la fabrication des ensembles réglants, et de l'opération de leur réglage d'ajustement en fréquence.The invention relates to the field of the manufacture of watch components, and in particular to the manufacture of regulating assemblies, and the operation of their adjustment of frequency adjustment.
Traditionnellement, les balanciers et spiraux sont fabriqués, puis triés en un grand nombre de classes. Pour constituer un ensemble balancier-spiral susceptible d'osciller au voisinage d'une certaine fréquence d'oscillation, il convient alors de prélever un balancier et un spiral chacun dans une classe capable de se rapprocher de cette fréquence, puis d'ajuster la paire ainsi formée pour obtenir réellement la fréquence désirée, en ajustant la longueur du spiral, ou/et en modifiant l'inertie du balancier.Traditionally, balances and spirals are made and then sorted into a large number of classes. To constitute a balance-spiral assembly capable of oscillating in the vicinity of a certain frequency of oscillation, it is then necessary to take a balance and a spiral each in a class capable of approaching this frequency, then to adjust the pair thus formed to actually obtain the desired frequency, adjusting the length of the hairspring, and / or changing the inertia of the balance.
De ce fait, un volumineux en-cours de production est nécessaire pour satisfaire la demande. Et, malgré cet en-cours, des opérations restent nécessaires su le spiral et le balancier, qui ne sont pas prêts à l'emploi.As a result, a large volume of work in progress is needed to meet demand. And, despite this work in progress, operations are still needed on the balance spring and the pendulum, which are not ready for use.
La précision d'ajustement en fréquence dépend naturellement de l'ampleur de chacune des classes de spiraux et de balanciers, ce qui explique leur nombre élevé.Frequency adjustment accuracy naturally depends on the magnitude of each of the spirals and pendulum classes, which explains their high number.
L'invention se propose d'éliminer ces en-cours de production extrêmement coûteux, et de mettre en place un procédé nouveau qui permette de fabriquer, de façon extrêmement rapide et économique, des ensembles balanciers-spiral correctement ajustés à une fréquence d'oscillation donnée.The invention proposes to eliminate these extremely expensive work in progress, and to set up a new process which makes it possible to manufacture, extremely quickly and economically, balance-balance assemblies correctly adjusted to an oscillation frequency. given.
L'invention se propose, encore, de traiter en même temps la problématique d'équilibrage nécessaire pour les balanciers.The invention also proposes to deal at the same time with the balancing problem necessary for the pendulums.

- on détermine les paramètres de fabrication, pour avoir, entre les distributions gaussiennes des valeurs de fréquence théoriques des balanciers et des spiraux un écart correspondant à une diminution d'inertie possible de chaque balancier,
- on prélève au hasard un spiral et un balancier quelconques
- on effectue un usinage d'ajustement d'équilibrage dudit balancier prélevé pour l'amener dans une tolérance d'équilibrage donnée si nécessaire, et un usinage complémentaire d'ajustement d'inertie, en fonction du couple dudit spiral prélevé,
- capability is controlled in capability according to normal laws of predetermined maximum mean and standard deviation, for machining spirals capable of a given oscillation frequency for a predetermined balance inertia, each finished, cut for its pitonnage and ready to assembly, and rockers capable of said frequency for a predetermined pair of hairspring.
- the manufacturing parameters are determined so as to have, between the Gaussian distributions of the theoretical frequency values of the balances and the spirals, a difference corresponding to a possible decrease in inertia of each pendulum,
- we randomly take a hairspring and any balance
- balancing adjustment machining of said picked-up rocker is carried out to bring it into a given balancing tolerance if necessary, and complementary machining of inertia adjustment, as a function of the torque of said hairspring taken,

De façon plus particulière, ce procédé est tel que :
- on fabrique, dans un processus de production piloté par des moyens de pilotage de capabilité des moyens de production suivant une loi normale de moyenne ms prédéterminée et d'écart-type σs limité à une valeur prédéterminée, une population de spiraux capables d'une fréquence d'oscillation donnée N0 en fonction d'une inertie de balancier JO de référence, ces spiraux étant chacun fini, de longueur prédéterminée pour son pitonnage et prêt à être assemblé avec un balancier pour constituer un ensemble balancier-spiral,
- on fabrique, dans un processus de production piloté par des moyens de pilotage de capabilité des moyens de production suivant une loi normale de moyenne mb prédéterminée et d'écart-type σb limité à une valeur prédéterminée, et dans une tolérance de balourd donnée, une population de balanciers capables de cette fréquence d'oscillation donnée N0 en fonction d'un couple de spiral CO de référence ;
- on détermine les paramètres de fabrication, selon ces lois normales, des balanciers et des spiraux afin de qualifier la moyenne mb de la population de balanciers, en fonction de la moyenne ms de la population de spiraux, de telle façon qu'il subsiste, entre :
- d'une part la distribution gaussienne des valeurs de fréquence théoriques pour chaque balancier en fonction du couple de spiral CO de référence,
- et d'autre part la distribution gaussienne des valeurs de fréquence théoriques pour chaque spiral en fonction de l'inertie de balancier JO de référence,
un écart correspondant à une diminution d'inertie possible de chaque balancier;
et, pour constituer un tel ensemble balancier-spiral et procéder à son ajustement en fréquence d'oscillation : - on prélève au hasard parmi la population de spiraux un spiral quelconque Sx et on prélève au hasard parmi la population de balanciers un balancier quelconque By,
- puis on effectue une opération d'ajustement d'inertie consistant à effectuer, simultanément ou successivement :
- un usinage d'ajustement d'équilibrage du balancier prélevé By pour l'amener dans une tolérance d'équilibrage donnée si le balourd de ce balancier prélevé By est supérieur à la tolérance d'équilibrage donnée, et

- and this possible reduction of inertia is limited to the maximum value of the unbalance tolerance.
Dans une variante de réalisation, on effectue un usinage par enlèvement de matière sur le balancier prélevé By pour une première mise d'inertie sans équilibrage, puis, après une mesure du balourd de ce balancier By et un calcul de définition d'usinage, un usinage d'équilibrage et de deuxième mise d'inertie à une valeur calculée pour que l'ensemble balancier-spiral Sx-By oscille à la fréquence d'oscillation N0.In an alternative embodiment, a machining is carried out by removal of material on the balance taken By for a first inertia setting without balancing, then, after a measurement of the balance of this By balance and a calculation of machining definition, a balancing machining and second setting of inertia to a value calculated so that the Sx-By spiral balance assembly oscillates at the oscillation frequency N0.
Dans un mode de réalisation particulier, notamment pour mettre en évidence une éventuelle contrefaçon, on effectue un usinage par enlèvement de matière sur le balancier By en réservant certaines premières surfaces du balancier By à cet usinage de première mise d'inertie, et en réservant certaines deuxièmes surfaces de ce balancier By à l'usinage d'équilibrage et de deuxième mise d'inertie.In a particular embodiment, in particular to highlight a possible counterfeit, machining is carried out by removal of material on the By balance by reserving certain first surfaces of the By balance to this machining first inertia setting, and reserving certain second surfaces of this By balance to balancing machining and second inertia setting.
On peut alors déterminer ces premières surfaces comme distinctes de ces deuxièmes surfaces du balancier By.These first surfaces can then be determined as distinct from these second surfaces of the By balance.
Il est possible d'imposer la position des différentes surfaces, et on peut notamment définir les premières surfaces et les deuxièmes surfaces du balancier By au moins en interdisant tout usinage dans certaines troisièmes zones du balancier By) réservées pour la réception de masselottes d'équilibrage ou de composants rapportés.It is possible to impose the position of the different surfaces, and it is possible in particular to define the first surfaces and the second surfaces of the beam By at least prohibiting any machining in certain third zones of the beam By) reserved for the reception of balancing weights or reported components.

Dans une variante avantageuse, on calcule le volume de matière à enlever en chaque zone d'usinage, et on répartit le débit de matière sur une surface suffisante pour respecter des sections minimales prédéfinies dans les différentes zones du balancier By, de façon à prévenir tout problème de tenue en fatigue.In an advantageous variant, the volume of material to be removed in each machining zone is calculated, and the flow rate of material is distributed over a sufficient area to respect predefined minimum sections in the different zones of the By beam, so as to prevent any problem of fatigue resistance.
En particulier, on calcule le volume de matière à enlever en chaque zone d'usinage de façon à ne pas dépasser un certain débit en masse prédéfini par rapport à la masse totale du balancier By, et on répartit le débit de matière au niveau de surfaces suffisamment éloignées de l'axe de pivotement du balancier By pour atteindre la valeur d'inertie calculée pour le balancier By.In particular, the volume of material to be removed in each machining zone is calculated so as not to exceed a certain predefined mass flow rate with respect to the total weight of the by-beam, and the flow of material is distributed at the level of surfaces. sufficiently far from the pivot axis of the By beam to reach the calculated inertia value for the By beam.
De préférence, après ajustement final de l'inertie du balancier By pour constituer un ensemble balancier-spiral Sx-By de la fréquence d'oscillation N0 recherchée, en fonction du couple mesuré du spiral Sx, on chasse au repère l'un sur l'autre ce spiral Sx sur ce balancier By.Preferably, after final adjustment of the inertia of the By balance to constitute a Sx-By balance-spring assembly of the desired oscillation frequency N0, as a function of the measured torque of the spiral Sx, the reference mark is shifted to one on the this other spiral Sx on this pendulum By.
