Definitions

  • the present invention relates generally to the transmission members, or bearings, intended to be interposed between a first member, said here for convenience driving member, and a second member, said here for convenience driven member, and is for example the case where the driven member constitutes by itself a vibrating machining tool or is associated with such a tool.
  • the transmission members proposed to date for this purpose can for example constitute bearings comprising shock absorbers made of elastic material, bearings using elastic diaphragms, or bearings with hydro or aerodynamic suspension.
  • At least some of them comprise, on the one hand a hollow housing, for fixing to the frame forming a reference support, and on the other hand, a core mounted floating in all directions in said housing, said core comprising at least two arms. , which both open to the outside of the housing, and to each of which any driving or driven member is liable to be subjected.
  • the two arms of the floating core are always in practice arranged in alignment with one another.
  • the driving member and the driven member are both inevitably interposed between the head of the machine frame carrying the assembly and the work table of this frame on which the workpiece is placed. to work.
  • the subject of the present invention is in particular a transmission member or bearing with suspension by fluid suitable for avoiding these drawbacks and also having other advantages; it also relates to a machining machine using such a transmission member.
  • the arrangement according to the invention which is therefore characterized, according to this aspect, by the fact that the arm to which the driving member is coupled and that to which the driven member is subjected are not necessarily in alignment with one another, and which takes advantage of the experimental fact that a part, one arm of which is subjected to vibrations, similarly reflects these vibrations on the other arms which it may comprise, whatever the 'orientation of these relative to the arm subjected to said vibrations, advantageously allows a significant reduction in the size of the assembly.
  • the transmission member according to the invention advantageously allows the continuous application of vibrations to such a driven member, even when it is in the course of work, and therefore under load .
  • the housing of the transmission member according to the invention is externally in the form of a generally parallelepipedal block.
  • the transmission member according to the invention advantageously lends itself, by stacking, to a battery setting with several similar transmission members, for simultaneous work, in parallel, of a plurality of separate parts on the same machine.
  • the transmission member 10 can, for example, be fixed to the frame head 45 of any machining machine, and in particular of a machine for machining by electro-erosion or electro-chemistry, facing any support, work table 55 for example, suitable for holding, for example, the workpiece 57.
  • the supply of the vibration generator 11, and possibly also that of the electrode 12, is systematically interrupted, in order to d 'prevent the core 14 from touching the housing 13 under load
