Definitions

  • the field of the invention relates to that of manufacturing processes for timepieces.
  • the machining of timepieces is carried out in several stages, such as, for example, the manufacture first of all of the pinion and of the axis of rotation and in a second stage the assembly of a wheel with the pinion and the 'axis.
  • This method has many limits such as for example that of alignment so that the pinion and the wheel mesh simultaneously, not to mention the orientation, the flatness of the parts and their centering.
  • the assembly of the wheel on the axis of rotation requires a certain force on the parts and can cause deformation of the wheel or the axis.
  • said manufacturing method (500) comprises a step of rotating during said at least one step of exposing at least a first portion of said at least one single piece and / or during said at least one step of exposing at least a second portion of said at least one single piece.
  • said manufacturing method (500) comprises at least one step of forming at least one first relief, in particular at least one first convex relief or at least one first concave relief, and / or at least one step forming at least one second relief, in particular at least one second convex relief or at least one second concave relief.
  • the crystalline, composite or amorphous material is ceramic, quartz, glass, precious stone, metal, silicon, polymer, biological material and / or cermet.
  • said step of transmitting a first modulation and / or a second modulation of the laser light in power and in time is configured to manufacture an axis of clockwork mechanisms, a pivot of clockwork mechanisms. 'clockwork, a stem of clockwork mechanisms, a pin of clockwork mechanisms, a gear of clockwork mechanisms, a wheel of clockwork mechanisms and / or a pinion of clockwork mechanisms or a combination of these mechanical timepieces, preferably an axis-pivot-pinion or pin-pinion-wheel.
  • said step of modulating the laser light in power and in time is configured to smooth and / or polish a surface of said one-piece mechanical timepiece.
  • the smoothing and / or polishing step can be carried out by the same process.
  • said first modulation and / or second modulation of the laser light in power and in time is configured to satin-finish and / or mattify a surface of said one-piece mechanical timepiece.
  • said manufacturing process comprises at least one step of structuring, coloring, marking, cutting, drilling, etching and / or ablation.
  • the present invention relates to the use of a laser light source for forming at least one first relief, in particular at least one first convex relief or at least one first concave relief, at least one second relief, in particular at least one second convex relief or at least one second concave relief and / or for structuring, coloring, marking, cutting, drilling, engraving and / or sculpting a one-piece mechanical timepiece.
  • the present invention relates to the use of a laser light source to form a one-piece mechanical timepiece comprising at least a first portion 530 with at least a first volume and at least a second portion 550 with a second volume.
  • said timepiece is manufactured according to a manufacturing process 500 by laser light described below.
  • a single piece of crystalline, composite or amorphous material which can be, depending on the part to be manufactured, ceramic, quartz, glass, precious stone, metal, silicon, polymer , biological material such as wood, mother-of-pearl to name a few, and / or cermet.
  • Said one-piece mechanical timepiece is placed in the path of said laser light which emits a first modulation 520 in power, geometry and time.
  • said laser light is modulated according to certain parameters so that upon exposure of at least a first portion 530 of said one-piece part, a first volume is formed.
  • said one-piece mechanical timepiece is placed in the path of said laser light which emits a second modulation 540 in power, geometry and time, preferably different from the first modulation 520.
  • a second volume is formed.
  • said second modulation 540 just like said first modulation 520, of the laser light in power and time so as to satin-finish and / or mattify a surface of said one-piece mechanical timepiece, and this, preferably, at the end of the formation of the second volume.
  • said at least one integral part is rotated 560 in order to obtain one-piece mechanical timepieces having symmetry.
  • a step of structuring 570 of coloring, of marking, of cutting, of drilling, of etching and / or of ablation, which can be inserted at any time of said manufacturing process 500 , such as for example during the emission of the first modulation (520) and / or of the second modulation (540) of said laser light in power.
  • the result or the product of this manufacturing process can be in the form of an axis of clockwork mechanisms, of a pivot of clockwork mechanisms, of a rod of clockwork mechanisms, of a pin of clockwork mechanisms, of a gear of clockwork mechanisms, of a wheel of clockwork mechanisms and / or of a pinion of clockwork mechanisms or of a combination of these mechanical clockwork parts , such as preferably an axis-pivot-pinion or axis-pinion-wheel.
  • One of the advantages of this process is the manufacture of a one-piece mechanical timepiece having a difference in thickness and / or height, between a pinion and an axis for example, minimal.
  • the one-piece mechanical timepiece parts produced by said method of the invention, are manufactured without misalignment between the different parts of the mechanical timepiece or deformation of the latter, and making it possible to maximize their dimensions in order to increase their size.
  • mechanical robustness because the limitations of an assembly are no longer necessary.
  • the figs. 4A and 4B show a one-piece mechanical timepiece 100 produced by said manufacturing method according to the invention which makes it possible to manufacture one-piece mechanical timepieces, with a wheel and a pinion for example, without misalignment between the different parts of the mechanical part clockwork or deformation of all or part of the latter, and with optimal dimensions allowing a reduced bulk but improved mechanical robustness.
