摘要:
An assembly of an axially extending member, made of a first material, in an aperture of a part, made of a second material having no plastic domain. The part includes pierced holes forming an elastic deformation mechanism distributed around the aperture thereof. Further, the member includes an elastically and plastically deformed, radially flared portion that radially grips a wall of the part surrounding the aperture by stressing the elastic deformation mechanism, so as to secure the assembly in a manner that is not destructive for the part. The assembly can be used in the field of timepieces.

The balance-spring is formed by a first assembly, comprising the coils (3) and the outer curve (2), made in a first material such as Elinvar having an elastic torque that is insensitive or almost insensitive to elongation, temperature and magnetic field variations, and by a second assembly secured to the first assembly, comprising in particular the inner curve (4) made of a second material essentially selected for its mechanical properties and for the shapeability of said inner curve (4) along the most favourable contour for concentric expansion of the balance-spring, such as a Grossmann curve (14), said second assembly also being able to comprise a collet (5).
摘要:
An assembly including a member made of a first material, which is axially driven into a circular aperture of a part made of a second material, having no plastic domain, using an intermediate part made of a third material and mounted between the member and the part is disclosed. The intermediate part is a continuous cylinder including a hole for receiving the member so that the intermediate part absorbs radially and in a uniform manner, at least part of the axial driving force of the member. The part includes pierced holes forming elastic deformation units distributed around the circular aperture thereof for absorbing any of the radial force not absorbed by the intermediate part, so as to secure the assembly in a non-destructive manner for the part.
摘要:
The balance-spring (1) includes a plurality of coils (3) of which the end (6, 8) of the outer curve (2) is rigidified by deformation in order to define accurately the setting point (7) of said balance-spring, said deformation being able to be achieved by bending the end (6) of the outer curve (2) through 90° in a plane perpendicular to the height of the balance-spring (1) or by folding down through 180° a portion of the end (8) of the outer curve (2) against the inner or outer face of said end (2).

摘要:
A method for adjusting an oscillation frequency of a sprung balance assembly, in which a removal or a displacement of material is conducted on a component of this sprung balance assembly under an effect of a pulse of a laser source to conduct a micromachining or microfusion operation on the material of this component to vaporize or displace this material. This pulse is controlled by a controller configured to generate, sequence, interrupt any pulse and to control movements of a beam of this laser source, and the controller is automatically controlled by a measuring or comparing mechanism.

An assembly including a member made of a first material, which is axially driven into a circular aperture of a part made of a second material that is brittle, using an intermediate part made of a third material and mounted between the member and the part is disclosed. The intermediate part is a continuous cylinder including a hole for receiving the member so that the intermediate part absorbs radially and in a uniform manner, at least part of the axial driving force of the member. The part includes pierced holes forming elastic deformation units distributed around the circular aperture thereof for absorbing any of the radial force not absorbed by the intermediate part, so as to secure the assembly in a non-destructive manner for the part.
