  • the welding tool 1 3 has a cylindrical pin portion 1 4 having a small outer diameter with respect to the screw hole of the nut 1 and is coaxial with the tip surface of the cylindrical shoulder portion 1 5 having a larger outer diameter. It has a continuous shape, and the total length of the pin portion 1 4 is the nut 1, first, second member
  • the material of the welding tool 1 3 is made of steel which is harder than aluminum alloy and has a higher softening temperature.
  • This assimilation layer 2 7 also entrains the material derived from the periphery of the screw hole of the nut 1, and finally the shoulder portion 15 of the welding tool 1 3 is pressed against the second member 18. It will be attached.
  • joining tool 13 is pulled away from the second member 18, the assimilation layer 2 7 is cured, and the backing member 8 is pulled away from the first member 17, thereby the first and second members. Joining of 1 7 and 1 8 is completed.
  • the hole 2 8 of the second member 18 after the pin portion 14 of the joining tool 1 3 has been pulled out can be used for port fastening of another member if female threading is performed.
  • an assimilated member having a parallel groove on the wall surface of the opening or a material derived from the periphery of the screw hole of the nut 1 is wound on the assimilation layer 27.
  • a member having no groove on the inner wall of the opening may be used.
  • the member joining structure of the present invention can be applied to joining and assembling processes for various parts.

Abstract

Structure servant à accoupler des éléments, en particulier, des éléments présentant une faible épaisseur ou des éléments de différents matériaux. Cette structure possède un écrou (1), un premier élément (2) superposé sur l'écrou (1), de sorte qu'un orifice (2) déjà présent dans le premier élément (2) se prolonge dans le taraudage de l'écrou (2), ainsi qu'un deuxième élément (4) superposé sur le premier élément (3), de manière à recouvrir l'orifice (2). On fait pénétrer le matériau du deuxième élément (4)dans l'orifice (2) du premier élément, puis dans le taraudage de l'écrou (1) au moyen de friction thermique et d'un écoulement plastique du matériau générés par l'outil d'accouplement (5).
