摘要:
A method for adjusting oscillation frequency of a spring balance assembly. A removal and/or an addition and/or a displacement of material is/are conducted on a component of the assembly under effect of a pulse of a transformation mechanism to conduct a micromachining and/or microfusion operation on the material of the component or of an addition material to vaporize and/or displace and/or weld the material. The pulse is controlled by a controller configured to generate, sequence, interrupt any pulse and to control movements of a beam of the transformation mechanism, wherein the controller is connected to or automatically controlled by a measuring or comparing mechanism.

An oscillating mechanism for a timepiece movement, including a first rigid element and a second rigid element, each one fixed on a different element of the movement and at least one of which is mobile relative to the other and pivots about an axis. The mechanism is monobloc and flexible with a variable geometry, and includes a first elastic restoring mechanism producing an elastic connection between the first rigid element and an intermediate rigid element, and a second elastic restoring mechanism producing an elastic connection between the intermediate element and the second rigid element, which all are coplanar according to one plane and configured to be deformed according to the plane.

摘要:
A method of assembling a member made of a first material in a part made of a second material having no plastic domain, includes forming the part with an aperture, inserting a radially flared portion of the member into the aperture, without any stress, and elastically and plastically deforming the flared portion of the member in the aperture by moving two tools towards each other axially, respectively on the top and bottom parts of the flared portion, so as to exert a radial stress against the wall of the part surrounding the aperture, causing the elastic deformation of the part, to secure the assembly in a manner that is not destructive for said part. The member can be a timepiece.
