Definitions

  • the invention relates to an assembly of a part whose material does not comprise a plastic field with a member comprising another type of material.
  • the object of the present invention is to overcome all or part of the disadvantages mentioned above by proposing a glueless assembly capable of securing a part whose material does not include a plastic field with a member comprising a ductile material such as, for example, a metal or a metal alloy.
  • the invention relates to an assembly of an axially extending member made of a first material in the opening of a part made of a second material having no plastic domain, characterized in that the part comprises perforations forming elastic deformation means distributed around its opening and in that said member comprises an elastically and plastically deformed portion which radially clamps the wall of said part surrounding the opening by urging said elastic deformation means to secure the assembly of non-destructive way for said piece.
  • This configuration advantageously makes it possible to secure the whole piece - intermediate part - body without bonding with a usual member to the precision controlled while ensuring that the part does not undergo destructive efforts even if it is formed, for example, from silicon.
  • the invention relates to a timepiece characterized in that it comprises an assembly according to one of the preceding variants.
  • This method advantageously makes it possible to radially fasten the member and the workpiece without any axial force being applied to the workpiece. Indeed, advantageously according to the invention, only a radial elastic deformation is applied to the workpiece. Finally, such a method makes it possible to secure the whole piece - intermediate part - body by adapting to the manufacturing dispersions of the various constituents.
  • the invention relates to an assembly and its method for joining a fragile material, that is to say not having a plastic domain such as a material based on silicon, with a ductile material such as a metal or a metal alloy.
  • This assembly was designed for applications in the watchmaking field. However, other areas can perfectly be imagined as including aeronautics, jewelry, automotive or the arts of the table.
  • this assembly is made necessary by the growing share of fragile materials such as those based on silicon, quartz, corundum or more generally ceramic.
  • fragile materials such as those based on silicon, quartz, corundum or more generally ceramic.
  • the invention relates to an assembly between a member made of a first material, for example ductile such as steel, in the opening of a part made of a second material that does not comprise a plastics field, such as a silicon-based material, by deformation of a portion of the member which is mounted in the opening of said piece.
  • a member made of a first material for example ductile such as steel
  • a part made of a second material that does not comprise a plastics field, such as a silicon-based material
  • said member comprises an elastically and plastically deformed portion which radially clamps the wall of said part surrounding the opening by biasing said elastic deformation means to non-destructively fasten the assembly for said part.
  • the outer wall of the portion of the member in the opening is substantially shaped corresponding to the opening of the part to exert a substantially uniform radial stress on the wall of the room surrounding said opening.
  • the opening in the fragile part is circular, it is preferable that the outer wall of the portion of the member in the opening is in substantially continuous cylinder shape, that is to say without slot radial or axial a journeyage, is made preferable to avoid localized stresses on part of the wall of the room surrounding the opening which are suitable for initiating break points.
  • the portion of the member present in the aperture with a shape corresponding to the aperture can be interpreted, if the section of the opening is circular, as a solid disc whose outer wall is continuous, that is to say without groove or more generally material discontinuity.
  • the corresponding shape of the part of the member present in the opening thus allows, by elastic and plastic deformation, to generate only a substantially uniform radial stress on a maximized surface of the wall of the part around the opening.
  • the piece comprises perforations forming elastic deformation means which are distributed around and away from its opening and which are intended to absorb said radial forces to restore them once the stress of the tools released in order to, in the end, fasten the assembly non-destructively for said part.
  • the anchor 1 as an example comprises two assemblies 2, 12 according to the invention intended respectively to secure the stinger 7 and the member, here a pivot axis 17, with its rod 5.

  • each assembly 2, 12 comprises perforations 6, 16 made in the rod 5 around an opening 8, 18 and which are intended to form elastic deformation means. It is therefore understood that the assembly 2, 12 is sufficiently strong not to generate relative movements between its components.
  • the escape wheel 3, and more generally the mobile 3, comprises, by way of example, an assembly 22 intended respectively to secure the member, here a pivot axis 27, with the body 25 of the wheel 3.
  • the assembly 22 comprises a discoidal portion 24 formed in shape with the member 27 and cooperating with the body 25 of the wheel 3.
  • the assembly 22 comprises cut-outs 26 made in the hub around an opening 28 of the wheel 3 and which are intended to form elastic deformation means.
  • the example of the assembly 22 can be applied to any type of mobile.
  • the member 27 may comprise, in addition to the portion 24, in one piece a pinion to form the finished mobile.

  • the cut-outs 26 "repeat the cut-outs 26 'of the figure 4 with, in addition, slots 36 for communicating the third set of holes 35 with the opening 28.
  • the series of holes 31, 33 and 35 and the slots 36 are used to form elastic deformation means capable of absorbing radial stresses, that is to say forces exerted from the center of the opening 28 to the wall of the body 25 surrounding said circular opening.
  • the two or three series may be more or less close to each other and / or different shapes and / or different dimensions depending on the desired maximum displacement and the desired stress to deform the beams 32, 34.

It can be seen that the cut-outs 26 "'are similar to those 26" of the figure 5 however, the three sets of holes are spaced apart from each other. In addition, it is visible that the shapes and dimensions as well holes that slots are different. So we understand that the alternative of figure 6 modifies the rigidity of the elastic deformation means in the brittle material.

  • each hole 53 of triangular shape communicates with the opening 28 by a notch 57. It can be seen at figure 7 that the perforations 46 thus form substantially trapezoidal beams 52 which are separated from each other by the notches 57. It is also noted that each beam 52 is centered on an oblong hole 51 which which makes each beam 52 movable radially according to the thickness of an oblong hole 51.
