Abstract
An alignment structure, which can be used in a welding method for joining a first workpiece and a second workpiece, includes an alignment protruded portion formed to be protruded from an end face of the first workpiece that is a metal plate, and an alignment depressed portion formed on a surface of the second workpiece such that that the alignment protruded portion is entered thereinto and engaged therewith, and the first workpiece is aligned in an orthogonal manner with respect to the second workpiece due to an engagement of the alignment protruded portion with the alignment depressed portion in which the end face contacts with the surface of the second workpiece.
Claims4
An alignment structure comprising:
- an alignment protruded portion formed to be protruded from an end face of a first workpiece that is a metal plate;
- and
- an alignment depressed portion formed on a surface of a second workpiece such that that the alignment protruded portion is entered thereinto and engaged therewith,
- wherein the first workpiece is aligned in an orthogonal manner with respect to the second workpiece due to an engagement of the alignment protruded portion with the alignment depressed portion in which the end face of the first workpiece contacts with the surface of the second workpiece.
A method for manufacturing a workpiece, the method comprising:
- aligning a first workpiece in an orthogonal manner with respect to a second workpiece by engaging an alignment protruded portion of the first workpiece with an alignment depressed portion formed on the second workpiece,
- wherein the alignment protruded portion is formed by
- forming a projection that projects from an entire height of an end face of the first workpiece that is a metal plate, and then
- deforming the projection plastically so as to protrude from a partial height of the end face through a stroke of a punch in a thickness direction of the first workpiece, the punch being movable in the thickness direction and located at a position causing a contact with the projection.
A welding method comprising:
- forming a projection that projects from an entire height of an end face of a first workpiece that is a metal plate,
- forming an alignment protruded portion by deforming the projection plastically so as to protrude from a partial height of the end face through a stroke of a punch in a thickness direction of the first workpiece, the punch being movable in the thickness direction and located at a position causing a contact with the projection,
- forming an alignment depressed portion on a surface of a second workpiece, against which the end face of the first workpiece is to be butted, at a position that is shifted from a given position onto which the first workpiece is to be abut by a height of the alignment protruded portion such that the alignment protruded portion is to be entered thereinto and engaged therewith,
- aligning the first workpiece at the given position on the second workpiece by butting the alignment protruded portion against the alignment depressed portion to be engaged with each other, and
- welding a butted portion to join the first workpiece and the second workpiece.
