Definitions
- the present invention relates to the field of watchmaking. It relates, more particularly, to a method of assembling a piece of hard material such as silicon, diamond or corundum, on a support axis.
- the present invention therefore provides a method of assembling a part on an axis, free from the aforementioned drawbacks.
- the assembly of the piece of hard material and the intermediate piece is independent of mounting on the support axis of the assembly.
- the invention also relates to a set of a piece of soft material and of a piece of hard material, the piece of soft material being pierced with a hole to be rigidly mounted on a support axis.
- the piece of soft material defines a range and a rim around the hole.
- the piece of hard material is pierced with an opening and is fitted on the edge of the piece of soft material, resting on the scope.
- the piece of soft material has a deformation not resulting from a radial compression, solidarisant permanently, axially and angularly, the piece of soft material and the piece of hard material.
- the flange of the piece of soft material is of height H , the thickness e of the piece of hard material being less than the height H , so that the piece of soft material has a flange protruding from the piece of hard material.
- the collar is folded over the piece of hard material.
- the opening of the piece of hard material has facets facing the edge of the intermediate piece, the facets defining interstices between the piece of hard material and that of soft material. The latter has deformations cooperating with the interstices to secure the two parts.
- the figures illustrating the invention relate to the particular example of the assembly of a spiral 10, typically silicon, on its axis.
- the invention can be adapted to the assembly of any piece of hard material, such as silicon, diamond or corundum, on a support axis.
- the axis may optionally comprise a toothing thus defining a pinion, on which can be assembled a wheel of hard material.
- the assembly method according to the invention requires the provision of an intermediate piece of soft material.
- soft material is meant a material capable of plastic deformation, in particular during a driving operation.
- the material used is preferably softer than the piece of hard material and can thus be selected from gold or nickel or copper-based alloys.
- the intermediate piece is a ferrule 12, to which the inner end of the spiral is intended to be fixed.
- the shell 12 has a cylindrical tube 14 pierced with a hole 16 intended to be rigidly mounted on the axis supporting the hairspring 10. It has an outside diameter d, and extends on its outer periphery, by a portion of diameter D greater than d .
- the portion defines a bearing 18 concentric with respect to the hole 16, and a flange 20, the bearing surface 18 and the flange 20 being disposed on the side intended to receive the hairspring 10.
- the spiral 10 has in its center an opening of diameter close to d .
- the hairspring 10 is fitted to the rim 20 of the shell 12 and is resting on the bearing surface 18. It must be understood by “adjusting" that the opening is dimensioned so that the hairspring 10 is mounted on the shell 12 with a slight clearance or a very slight tightening. The two pieces are not then assembled permanently.
- the flange 20 of the ferrule 12 is of height H , while the thickness e of the spiral 10 is less than the height H. In this way, the flange 20 protrudes from the spiral 10 and forms a flange 22 ( figure 1b ).
- the deformation of the flange 22 is by riveting, which allows a particularly precise control of the intensity and direction of the force applied to the ferrule.
- the deformation of the collar 22 could also be effected by thermal riveting, in particular by means of a laser, possibly with welding between the spiral and the ferrule. The proposed techniques can deform the ferrule 12 to secure it with the spiral 10, without the latter undergoes significant radial stress.
- the ferrule does not undergo radial compression, that is to say that the deformation of the ferrule does not result from a compression exerted inside the hole 16, typically by a driving. Such an operation would lead to exerting too much stress on the hairspring.
- the assembly thus formed by the ferrule 12 and the hairspring 10 can then be mounted rigidly and permanently on the support shaft, by driving, riveting, laser welding or any other suitable technique.
- the hairspring 10 thus suffers a minimum of direct stress and very little radial deformation during assembly on the axis.
- the assembly of the hairspring 10 and the shell 12 is independent of mounting on the support axis of the assembly that these two parts form.
- the hairspring 10 and the shell 12 thus form a perfectly usable assembly that can be counted and stored.
- the counting of the spiral is an operation which consists in determining the length of a spiral coupled to a pendulum so that it has the desired number of oscillations.
- the proposed method does not involve a part increase greatly the thickness of the assembly fixed on the axis and provides excellent centering spiral 10.
- the opening of the spiral 10 has facets 24 on its inner wall, intended to be positioned opposite the rim.
- These facets 24 may be regular and form a regular polygonal section, centered with reference to the opening.
- the dimensions of the polygon make it possible to adjust the spiral on the rim of the ferrule 12, resting on the span.
- the angles formed between two consecutive facets define interstices between the shell and the hairspring.
- the ferrule and the spiral can then be secured by deforming by thermal riveting, in particular by laser, the ferrule 12 so that it takes place at least partially in the interstices.
- the ferrule 12 it is not necessary for the ferrule 12 to have a collar 22, which makes it possible to reduce the height of the assembly as much as possible. Nevertheless, in a variant, it is conceivable to combine the thermal riveting of the facets 24 with the first embodiment, in which the flange 22 is folded down. Any geometry making it possible to obtain, on the one hand, precise zones of contact with the ferrule for adjusting these two parts together and, on the other hand, gaps between the two that can be filled by thermal deformation, for example laser, may be suitable for this embodiment.
- the rim of the ferrule 12 is equipped with an annular groove 26, parallel to the bearing surface 18.
- the groove 26 is disposed at a height h substantially equal to the thickness e of the hairspring 10.
- the groove 26 is opposite the edge of the hairspring 10 located on the opposite side to the scope 18, which advantageously allows absolutely avoiding any stress exerted on this edge during assembly of the ferrule-spiral assembly on the support axis, because this edge, very bright, may have greater fragility.
