Abstract
An electrode unit of a joining apparatus includes an abutting section provided with a tapered outer circumferential surface that contacts a tapered pressure-receiving surface by being inserted into an inside of a first metal member. The tapered outer circumferential surface inclines in a direction of getting closer to an axial center of the abutting section from one end side to another end side. At least part of the abutting section has a thickness elastically deformable in such a manner that the tapered outer circumferential surface aligns with the tapered pressure-receiving surface during application of a pressurizing force to the first metal member and a second metal member.
Claims5
A joining apparatus for joining a first joining surface and a second joining surface by electrification and pressure, the first joining surface provided on an outer circumferential side of a circular ring-shaped first metal member, and the second joining surface provided on an inner circumferential side of an insertion port of a second metal member into which the first metal member is inserted,
- at least part of the first joining surface being tapered inclining in a direction of getting closer to an axial center of the first metal member, from one end side toward the other end side in an axial direction of the first metal member,
- an inner circumferential side of the first metal member being provided with a tapered pressure-receiving surface inclining in the direction of getting closer to the axial center of the first metal member, from the one end side toward the other end side,
- the joining apparatus comprising an electrode unit having an abutting section,
- the abutting section being provided with a tapered outer circumferential surface that is configured to contact the tapered pressure-receiving surface when being inserted from the one end side toward the other end side into an inside of the first metal member,
- the tapered outer circumferential surface inclining in a direction of getting closer to an axial center of the abutting section as well as in an axial direction of the abutting section,
- at least part of the abutting section having a thickness capable of elastically deforming in such a manner that, during application of a pressurizing force to the first metal member and the second metal member, the tapered outer circumferential surface fits the tapered pressure-receiving surface,
- the abutting section is provided with at least one slit extending from a tip of the abutting section to a base end of the abutting section,
- wherein the at least one slit comprises a plurality of slits each of which extend from the tip of the abutting section to the base end of the abutting section, and wherein the plurality of slits are provide at intervals in a circumferential direction of the abutting section.
