Abstract

Method for adjusting the frequency of a balance-spring assembly formed at random from an entire production of springs and balances. The production means are set to limit the standard deviation (δs) of a given batch of springs to a predetermined maximum value (δsMax), and to limit the standard deviation (δb) of a given batch of balances to a predetermined maximum value (δbMax) with a given imbalance tolerance. The mean (mb) of said population of balances is described according to that (ms) of the springs in order to obtain a deviation corresponding to a maximum value of decrease of inertia of the balances, between the extreme values of the Gaussian distribution of the balances and that of the springs. A spring (Sx) is taken at random from said given batch of springs, and a balance (By) is taken at random from said given batch of balances. The inertia of said balance (By) is adjusted according to the torque value of said spring (Sx).

Description

Procédé d'ajustement en fréquence d'oscillation d'un ensemble balancier-spiral Domaine de l'invention  Method of adjusting the oscillation frequency of a sprung-balance assembly Field of the invention
L'invention concerne un procédé d'ajustement en fréquence d'oscillation d'un ensemble balancier-spiral d'horlogerie constitué au hasard parmi la totalité d'une production de spiraux et d'une production de balanciers.  The invention relates to a method for adjusting the oscillation frequency of a pendulum-balance spring assembly randomly formed among the totality of a production of spirals and a production of pendulums.
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.
Arrière-plan de l'invention Background of the invention
Traditionnellement, tel que décrit notamment dans « Théorie d'horlogerie » de C.A. Reymondin et al., ISBN 978-2-940025-10-7, publié par la Fédération des Ecoles Techniques de Suisse, Lausanne, 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, as described in particular in "Theorie d'Horlogerie" by CA Reymondin et al., ISBN 978-2-940025-10-7, published by the Federation of Technical Schools of Switzerland, Lausanne, the pendulums and spirals are manufactured, then sorted into a large number of classes. To constitute a balance-spiral assembly capable of oscillating in the vicinity of a certain oscillation frequency, 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 très volumineux en-cours de production est nécessaire pour satisfaire la demande. Et, malgré cet en-cours, des opérations restent nécessaires sur le spiral et le balancier, qui ne sont pas prêts à l'emploi.  As a result, a very large work in progress is needed to meet the demand. And, despite this work in progress, operations are still necessary on the balance spring and balance, 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.
Résumé de l'invention  Summary of the invention

Description détaillée des modes de réalisation préférés  Detailed Description of the Preferred Embodiments
L'invention concerne un procédé d'ajustement en fréquence d'oscillation d'un ensemble balancier-spiral d'horlogerie.  The invention relates to a method for adjusting the oscillation frequency of a pendulum-spiral clockwork assembly.
Cet ensemble balancier-spiral d'horlogerie est constitué au hasard parmi la totalité d'une production de spiraux et d'une production de balanciers.  This pendulum balance-hairspring assembly is randomly constituted among the totality of a production of spirals and a production of pendulums.
Selon ce procédé, pour s'affranchir de tout classement des balanciers et des spiraux, on effectue les opérations suivantes : :  According to this method, to overcome any classification of the balances and spirals, the following operations are carried out:
- on règle les moyens de production des spiraux sur une valeur moyenne ms prédéterminée, et on règle ces moyens de production des spiraux pour limiter l'écart-type as de la production de spiraux à une valeur maximale prédéterminée asMax,  the means for producing the spirals are set to a predetermined mean value ms, and these spiral production means are set to limit the standard deviation a from the production of spirals to a predetermined maximum value asMax,

pour effectuer la production : to make the production:
- d'une part d'un lot unique de spiraux d'un type donné dont la moyenne est capable d'une fréquence d'oscillation donnée NO pour une inertie de balancier J0 prédéterminée, chacun des spiraux étant fini, coupé pour son pitonnage et prêt à l'assemblage, et constituant une population unique de spiraux dont l'écart-type est propre au lot unique de production considéré,  on the one hand, a single set of spirals of a given type, the average of which is capable of a given oscillation frequency NO for a predetermined pendulum inertia J0, each of the spirals being finished, cut for its pegging and ready for assembly, and constituting a unique population of spirals whose standard deviation is specific to the single batch of production considered,
- et d'autre part d'un lot unique de balanciers d'un type donné, dont la moyenne est capable de la fréquence d'oscillation donnée N0 pour un couple de spiral C0 prédéterminé et constituant une population unique de balanciers dont l'écart-type est propre au lot unique de production considéré, - And secondly a single batch of balances of a given type, whose average is capable of the given oscillation frequency N0 for a pair of spiral C0 predetermined and constituting a single population of rockers whose standard deviation is specific to the single lot of production considered,
- on détermine les paramètres de fabrication, selon les lois normales de production 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 un écart correspondant à une valeur maximale de diminution d'inertie autorisée pour chaque balancier, entre les valeurs extrêmes de:  the manufacturing parameters are determined according to the normal production laws of the balances and spirals in order to qualify the average mb of the population of pendulums, as a function of the average ms of the spiral population, so that it remains a difference corresponding to a maximum value of decrease of inertia allowed for each balance, between the extreme values of:
- d'une part la distribution gaussienne des valeurs de fréquence théoriques pour chaque balancier en fonction du couple de spiral C0 de référence,  on the one hand, the Gaussian distribution of the theoretical frequency values for each pendulum as a function of the reference spiral torque C0,
- et d'autre part la distribution gaussienne des valeurs de fréquence théoriques pour chaque spiral en fonction de la inertie de balancier JO de référence,  and on the other hand the Gaussian distribution of the theoretical frequency values for each hairspring as a function of the pendulum inertia of reference JO,
- on prélève au hasard un spiral quelconque Sx dans le lot unique de spiraux, et on prélève au hasard un balancier quelconque By, parmi le lot unique de balanciers  - We draw at random any spiral Sx in the single set of spirals, and we randomly take a balance of any By, among the single batch of rockers
- on effectue si nécessaire un usinage d'ajustement d'équilibrage du balancier By prélevé pour l'amener dans une tolérance d'équilibrage donnée, et on effectue une opération complémentaire d'ajustement d'inertie, en fonction de la valeur du couple du spiral Sx prélevé,  if necessary, a balancing adjustment machining of the withdrawn by-balance is carried out to bring it into a given balancing tolerance, and a complementary operation of adjustment of inertia is carried out, as a function of the value of the torque of the spiral Sx taken,
de façon à constituer un ensemble balancier-spiral capable d'osciller à la fréquence d'oscillation NO après la opération d'ajustement d'inertie du balancier. La production suit une loi normale, dont les paramètres sont propres à chaque lot de production. On comprend que l'amplitude peut varier en fonction du lot de production. Certains lots auront ainsi des écarts-types plus importants que d'autres. so as to constitute a sprung-balance assembly capable of oscillating at the oscillation frequency NO after the pendulum inertia adjustment operation. Production follows a normal distribution, the parameters of which are specific to each production batch. It is understood that the amplitude may vary depending on the production batch. Some lots will have larger standard deviations than others.
L'intérêt de l'invention est de prélever un spiral parmi la totalité de la population de spiraux, sans avoir à décomposer cette population totale se spiraux en classes, comme dans l'art antérieur. Il en est de même pour le prélèvement d'un balancier, qui est effectué au hasard parmi la totalité d'une production. Les en-cours sont, de ce fait, limités à une production unique de spiraux, et à une production unique de balanciers.  The advantage of the invention is to take a spiral from the entire spiral population, without having to decompose this total spiral population into classes, as in the prior art. It is the same for the removal of a pendulum, which is performed randomly among the entire production. Work-in-progress is, therefore, limited to a single production of spirals, and to a unique production of pendulums.
Selon une caractéristique particulière de l'invention, l'opération d'ajustement d'inertie consiste 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 du balancier prélevé By est supérieur à la tolérance d'équilibrage donnée, et According to a particular characteristic of the invention, the inertia adjustment operation consists in performing simultaneously or successively: a balancing adjustment machining of the balance taken By to bring it within a given balancing tolerance if the balance of the balance taken By is greater than the given balancing tolerance, and
- un usinage complémentaire d'ajustement de l'inertie du balancier By, en fonction du couple, mesuré au préalable, du spiral prélevé Sx,  a complementary machining of adjustment of the inertia of the pendulum By, as a function of the torque, measured beforehand, of the spiral taken Sx,
de façon à constituer un ensemble balancier-spiral Sx-By capable d'osciller à la fréquence d'oscillation NO après la opération d'ajustement d'inertie. so as to constitute an Sx-By spring-balance assembly capable of oscillating at the oscillation frequency NO after the inertia adjustment operation.
Selon une caractéristique particulière de l'invention, on limite à la valeur maximale de la tolérance de balourd l'écart correspondant à une diminution d'inertie autorisée pour chaque balancier. According to a particular characteristic of the invention, the difference corresponding to a permitted decrease of inertia for each pendulum is limited to the maximum value of the unbalance tolerance.
Selon une caractéristique particulière de l'invention, on effectue un usinage par enlèvement de matière sur le balancier By pour une première mise d'inertie sans équilibrage, puis, après une mesure du balourd du 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 NO.  According to a particular characteristic of the invention, a machining is carried out by removal of material on the By balance for a first inertia setting without balancing, then, after a measurement of the balance By balance and a calculation of machining definition, a balancing and second inertia machining at a value calculated so that the Sx-By spiral balance assembly oscillates at the oscillation frequency NO.
Tout usinage par enlèvement de matière peut ici être effectué par laser, fraisage, tournage, ou autre.  Any machining by removal of material can here be performed by laser, milling, turning, or other.
Selon une caractéristique particulière de l'invention, 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 du balancier By à cet usinage d'équilibrage et de deuxième mise d'inertie.  According to a particular characteristic of the invention, in a particular embodiment, in particular to highlight a possible counterfeit, machining is carried out by removal of material on the balance By by reserving certain first surfaces of the balance beam By this first machining setting inertia, and reserving some second surfaces of the By balance to this balancing machining and second setting of inertia.
