Abstract

A combined device applies an axial force to a timepiece component, and simultaneously measures the axial distance between a reference and a surface of the component. The device includes a support carrying a measuring body which includes a measuring unit for carrying out an axial measurement of the position of this surface, and a controller operated by a user or by an automated manipulator, for applying to this surface, a characterised axial force transmitted to the bearing and measuring point by a calibrated axial resilient return device. The device is used by having a stack of flat, specific resilient elements, which are characterised by the combined force characteristic thereof as a function of the applied axial stroke, impart to the controller the rotational or axial stroke which corresponds to the specific axial force to be applied.

Dependent claims

A device for applying an axial force to a timepiece component, and for simultaneously measuring an axial distance between a reference and a surface of said component, said device comprising:

a support to carry at least one measuring body which includes at least one measuring means arranged to carry out an axial measurement of a position of said surface of a timepiece component, in an axial direction, said measuring means includes a feeler-spindle in contact with a bearing and measuring point and aligned therewith in said axial direction,
wherein said device is a combined device for simultaneously applying the force and measuring displacement of the surface to which the force is applied, and
wherein said device includes at least one control means, which is arranged to be operated by a user or by an automated manipulator, to apply to said surface a characterised axial force transmitted to said bearing and said measuring point by at least one calibrated axial resilient return means.

Dependencies are inferred from the claim text.
