  • Patent number: 11960246
    Abstract: A geometric inspection device for horological mobile components, including a headstock bearing a first spindle defining a first axis of rotation and a tailstock defining a second axis of rotation, on a common sole relative to which the headstock or the tailstock can move along a common direction parallel with the first axis of rotation. The device includes interchangeable micro-centering devices, at least one of the first spindle and the second spindle includes receiving means arranged to coaxially house a removable centering device, and at least one of the headstock and the tail stock includes pulling means arranged to pull without contact a micro-centering device axially along a common direction, opposite a space separating the headstock and the tailstock.

  • Patent number: 11953859
    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.

  • Patent number: 11402805
    Abstract: A device for measuring horological shakes, including a structure carrying an articulated mechanism with a compliant mechanism having a linear force/stroke characteristic connecting a first fixed element to a second element capable of moving linearly under the effect of an actuator manoeuvring same in a contactless manner in both directions, and a position sensor determining the position of the second element in a direction, and a load sensor determining the variation in the axial pushing or pulling load of the second element carrying a gripper clamping a mobile component, and/or the variation in the gradient of this load, generating a signal for triggering the position measurement during each sudden change in gradient of the load in each direction of running, to determine the shake of the mobile component, by comparing the positions measured during the sudden changes in gradient during the outward and return strokes.

  • Patent number: 10989617
    Abstract: A torque or force calibration device is for a unit intended to measure or to apply a torque or a force respectively. The device includes a first part, a second part, and at least one flexible element linking the first part to the second part. The second part is mounted to be mobile in rotation or in translation relative to the fixed first part. The device includes an abutment which limits the displacement of the second part and thereby sets the maximum torque or the maximum force of the calibration device.
