Embodiment Construction

[0047] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0048] FIG. 1 shows an example of a first metal member 11 and a second metal member 12 to which the metal member connection structure according to this embodiment can be applied. In addition, the shapes of the first metal member 11 and the second metal member 12 shown in the drawings in this embodiment are merely examples for explaining this embodiment, and the applied parts of this embodiment are not limited to these shapes. .

[0049] The first metal component 11 is a metal frame, and includes: a main body 13 and an annular portion 14 integrally formed with the main body 13 . The opening 15 is formed in the annular portion 14 which is, for example, a thin portion having a thickness t of 3 mm and a height h1 of 6 mm. The first metal component 11 is a molded die-cast product made of aluminum alloy or the like, which is also a material that lacks ductility.

Abstract

Disclosed is a metal component coupling structure and metal component coupling device capable of high strength and high precision coupling. An axial part (17) of a second metal component (12) is fitted in an annular part (14) of a first metal component (11), a restraint ring (33) is arranged on the outer circumference of the annular part (14) of the first metal component (11), and, by plastically deforming by applying force to the annular part (14), said annular part (14) is made to enter into a coupling groove (16) of the axial part (17), coupling the first metal component (11) and the second metal component (12) by mechanical interlocking.

Description

technical field [0001] The present invention relates to a connection structure and a connection device of metal parts connected by plastic flow. Background technique [0002] Conventionally, in order to fit and fix the shaft-shaped metal member to the ring-shaped portion of the frame made of metal, an integrated bracket portion is formed along the outer peripheral edge of the shaft-shaped metal member, and the bracket portion is fastened with bolts. on the rack. However, the weight and cost of components increase to form the bracket portion. In addition, productivity deteriorates due to fastening of bolts in mass production. Therefore, a method of plastically deforming and connecting metals is known (for example, refer to Patent Document 1). [0003] prior art literature [0004] Patent Document 1: Japanese Patent Application Laid-Open No. 5-318109 Contents of the invention [0005] However, in the connection of metal parts using plastic flow connection, in order to o...
