    Description
    Technical Field [0001] The present invention relates to a support for the removable fixing of an element intended to be attached to a watch dial during its manufacture.
    STATE OF THE ART [0002] The manufacture of indexes and other elements reported on watch dials presents particular difficulties due to the reduced size of these elements and the multiple operations which must be implemented. The dial indexes are frequently machined, polished, surface treated by chemical or electrochemical processes, by PVD / CVD or by varnishing, then cleaned and handled in different ways. During these operations, the elements are frequently glued to a support, then peeled off between each operation or at the end of the operations. This bonding presents difficulties in particular due to the traces of glue which sometimes remain, and the additional cleaning to remove the glue.
    An example of a known support is described in EP 2 455 824.
    We also know supports for maintaining elements reported on a dial during their manufacture by elastic clamping between deformable portions of the support. The present invention relates to this type of support. Conventional supports require the elements to be inserted, most often by hand or with tweezers, forcing them in a gap so as to deform a deformable portion. After machining, they are removed by pulling or pushing them against the elastic clamping force exerted by the deformable portion. This insertion and extraction operation is tedious. It also frequently happens that the elements are scratched or folded during their extraction. For example, when making indexes for dials with feet, it can happen that the index feet are bent by inserting or removing them from a gap. This risk can be reduced, but not eliminated, by limiting the clamping force exerted by the elastically deformable portion. The element is then less well held and may move or vibrate during its manufacture.
    Brief Summary of the Invention An object of the present invention is to provide a fixing support for the removable fixing of an element during its machining or its surface treatment free from the limitations of known supports.
    Another object of the invention is to provide such a support which is simple to produce.
    According to the invention, these objects are achieved in particular by means of a fixing support for the removable fixing of an element during its machining or its surface treatment, comprising: a disc;
    N spacings extending radially through the disc, and intended to accommodate said elements;
    a ring surrounding the disc and separated from the disc by a substantially annular slot;
    at least one spoke in one of said spaces, the inner end of the spoke being connected to said disc and the outer end of the spoke being connected to said ring, so that the rotation of said ring causes displacement and / or deformation of said spoke in its spacing, allowing an element to be fixed by wedging a portion of the element between the radius and an edge of the spacing.
    This support makes it possible to maintain elements during their manufacture and their handling by wedging them between spokes and one of the edges of the space.
    The spokes can be moved, that is to say pivoted, in one direction or the other by rotating the ring a few degrees relative to the disc. This will increase the average space between the spoke and one of the edges of the space, and reduce this space between the other side of the spoke and the other edge of the space. It is possible to insert and / or extract elements more easily by temporarily widening one of the spaces, then to hold it firmly by reducing this space during manufacturing or handling.
    The support may include Μ deformable tongues forming bridges connecting the ring with portions of the disc between said spacings. These tabs allow the disc to be secured to the ring, and to limit the maximum relative angular displacement. They also provide a return torque to bring the ring back to a rest position relative to the disc. The tongues are not directly linked to the spokes.
    The number N of spaces is advantageously equal to the number Μ of deformable tongues, each deformable tongue being placed at equal angular distance between two radii.
    The substantially annular slot between the disc and the ring is advantageously of constant width with the exception of at least Μ second enlarged portions in which the disc-ring distance is increased. A tongue crosses each enlarged portion. This configuration increases the length of the tabs.
    The tongues can be rectangular or trapezoidal.
    CH 714 921 A2 The spokes can be rectangular or trapezoidal.
    The substantially annular slot can be of constant width with the exception of at least N first enlarged portions, each said radius being connected to said ring through a first deformable portion passing through one of these first enlarged portions.
    It is possible to provide both Μ enlarged portions for the tongues and N enlarged portions for the spokes. The numbers N and Μ can be equal.
    The internal end of each spoke can be linked to the disc through a second deformable portion narrower than the spoke.
    The outer end of each spoke can be linked to the ring through a first deformable portion narrower than the spoke, in order to facilitate its deformation.
    The support may include a hole in the middle of the disc for mounting on an axis.
    The support can be produced by machining, stamping, laser cutting, water jet cutting, wire cutting or electroerosion. In a variant, it is produced by photolithography.
    The support can be made in one piece, without assembling separate parts.
    The support can be made of an electrically conductive material, for example stainless steel. This allows it to be used for electrochemical deposition operations on the elements. It also allows it to be cleaned for reuse.
    Brief description of the figures [0024] Examples of implementation of the invention are indicated in the description illustrated by the appended figures in which:
    Fig. 1 illustrates a top view of a support according to the invention.
    Fig. 2 illustrates a detailed view of the support of FIG. 1 at rest, that is to say when no element is inserted in the illustrated portion.
    Fig. 3 illustrates a detailed view of the support of FIG. 1 when an element is inserted in the illustrated portion.
    Example (s) of embodiment of the invention An example of a fixing support 1 according to the invention is illustrated in FIG. 1. It is intended in this example for fixing small horological elements during their manufacture, in particular for the manufacture of elements intended to be attached to dials, for example indexes. The same support, or supports coming within the scope of the invention, can also be used for the manufacture of other elements in watchmaking, jewelry, jewelry, micromechanics, or in the medical field for example.
    The support 1 is circular in shape and provided with a central hole 15 allowing it to be mounted on an axis in order to index it and to execute an operation successively on several elements mounted on the support and passing in turn on a workstation next to one of the positions. Certain operations, for example depositions, can be carried out simultaneously on all the elements mounted on the support. The support 1 is intended to be transported from one machine to another during the manufacture of the elements. It also serves as a support for the transport and handling of the elements during their manufacture on different workstations.
    The support 1 is advantageously made of conductive metal, for example stainless steel. It can thus be used as a conductor for electrochemical operations, for example depositions, and be reused by cleaning it if necessary.
    The support 1 comprises a central disc 3 provided with the opening 15 and a ring 7 concentric with the disc 3 and surrounding this disc. An annular slot 9 separates the ring from the disc. The ring is however connected to the disc by Μ deformable tabs 13 forming bridges. The ring can be pivoted relative to the disc by gripping it by portions 70 of its periphery, and by deforming the tongues 13. The annular slot 9 advantageously comprises a portion 90 widened around each tongue 13, thus making it possible to increase the length of the tongue 13 and therefore the possibility of deformation.
    The disc 3 is provided with a number N of radial spaces (slots) 5 each extending from the periphery of the disc inwards, without however reaching the opening 15. The number N of spaces is advantageously equal to the number Μ of tongues, although this is not essential.
    At least some of the N spaces - preferably each of these spaces - has a radius 1 which extends longitudinally over the greater part of the length of the space.
    CH 714 921 A2 The external end 111 of each spoke 11 is linked to the ring 7 by a deformable portion 112 forming a bridge through the annular slot 9. The annular slot 9 advantageously comprises a portion 91 widened around each deformable portion 112, thus making it possible to increase the length of the deformable portion 112. The width of the deformable portion 112 is advantageously less than that of the radius 11, to facilitate the deformation. Its thickness is advantageously identical to facilitate machining from a plate; however, it is also possible to provide a deformable portion of thickness thinner than the radius and than the ring 7.
    The internal end 110 of each spoke 11 is linked to the disc 3 by a deformable portion 113 forming a bridge across the bottom of the space 5. The annular slot 9 advantageously comprises a portion 91 widened around each deformable portion 113, thus making it possible to increase the length of the deformable portion 113. The width of the deformable portion 113 is advantageously smaller than that of the radius 11, to facilitate the deformation. Its thickness is advantageously identical to facilitate machining from a plate; it is however also possible to provide a deformable portion of thickness thinner than the radius and than the disc 3.
    The radius 11 is advantageously parallel to the edges of the space 5.
    The elements to be manufactured are inserted manually or using a manipulator between a radius and an edge of the space. In the case of elements intended to be attached to a dial, the elements can be fixed on the support by inserting one or more feet of each element in a spacing.
    A shoulder or a groove which is not illustrated can be provided in the radius or in the edge of the space to support an element, and thus determine its radial position while immobilizing it more in translation and / or in rotation. The radius 11 can be centered in the space 5 when the ring 7 is at rest, that is to say when no torque is exerted on this ring. In a preferred embodiment, the spoke 11 is closer to one edge of the spacing 5 than to the other, which makes it possible to maintain elements of different dimensions by inserting them either on one side of the spoke, or the other.
    After inserting the elements, the ring 7 is pivoted by a few degrees manually in a tightening direction, or using a gripper acting on the portions 70 or on the periphery of the ring, or on holes not shown through this ring, in order to move each of the spokes 11 into its location 5 by deforming the deformable portion 112 and, to a lesser extent, the deformable portion 113. The situation is illustrated in FIG. 3. In this position, the elements inserted between at least some of the spokes and the edge of the space 5 are held by pinching. The ring can be kept in this deformed position while it is on a manufacturing or processing station, and / or by means not shown making it possible to link the disc to the ring with a removable link. At rest, when no torque is exerted on the ring 7, it returns to its angular position in FIG. 2 thanks to the elastic return force of the deformable portions 112 and 113. It is possible to turn the support 1 with the elements and force the ring to rotate in the opposite direction to the previously used tightening direction, to release the elements by widening the between the radius and the edge of the spacing on the side of the elements.
    The support can be turned over and threaded on an indexing axis in one direction or the other. This makes it possible to insert the elements either on the narrow side of the space, or on the wide side, and to release it respectively to tighten it without modifying the direction of release or the directions of tightening.
