Abstract

A component manufacturing method includes a step of calculating, for a plurality of keyholes formed on a skin and disposed in a row along a first axial direction on the skin, a first imaginary line that passes an average position in a second axial direction perpendicular to the first axial direction and is parallel to the first axial direction, a step of calculating, for a plurality of keyholes formed on a frame and disposed in a row along a third axial direction on the frame, a second imaginary line that passes an average position in a fourth axial direction perpendicular to the third axial direction and is parallel to the third axial direction, and a step of superimposing the skin and the frame such that the first imaginary line and the second imaginary line coincide.

First claim

a first step of calculating, for a plurality of first positioning holes formed on a first member and disposed in a row along a first axial direction on the first member, a first imaginary line that is parallel to the first axial direction and that passes an average position in a second axial direction, wherein the second axial direction is perpendicular to the first axial direction;
a second step of calculating, for a plurality of second positioning holes formed on a second member different from the first member and disposed in a row along a third axial direction on the second member, a second imaginary line that is parallel to the third axial direction and that passes an average position in a fourth axial direction, wherein the fourth axial direction is perpendicular to the third axial direction; and
a third step of superimposing the first member and the second member such that the first imaginary line and the second imaginary line coincide.

2. The component manufacturing method according to claim 1 , wherein
the first step includes:
a step of detecting positions of the plurality of first positioning holes;
a step of calculating, based on the detected positions of the plurality of first positioning holes, the average position in the second axial direction of the plurality of first positioning holes; and
a step of calculating the first imaginary line passing the average position of the first positioning holes, and

the second step includes:
a step of detecting positions of the plurality of second positioning holes;
a step of calculating, based on the detected positions of the plurality of second positioning holes, the average position in the fourth axial direction of the plurality of second positioning holes; and
a step of calculating the second imaginary line passing the average position of the second positioning holes.

3. A component manufacturing system comprising:
a robot for attachment that attaches a second member to a first member, wherein
the robot for attachment includes a control unit that controls the robot for attachment, and
the control unit includes:
an imaginary-line calculating unit that:
calculates, for a plurality of first positioning holes formed on the first member and disposed in a row along a first axial direction on the first member, a first imaginary line that is parallel to the first axial direction and that passes an average position in a second axial direction, wherein the second axial direction is perpendicular to the first axial direction, and
calculates, for a plurality of second positioning holes formed on a second member different from the first member and disposed in a row along a third axial direction on the second member, a second imaginary line that is parallel to the third axial direction and that passes an average position in a fourth axial direction, wherein the fourth axial direction is perpendicular to the third axial direction; and

a driving control unit that drives the robot for attachment and superimposes the first member and the second member such that the first imaginary line and the second imaginary line coincide.

4. The component manufacturing system according to claim 3 , further comprising:
a robot for detection that detects positions of the plurality of first positioning holes and detects positions of the plurality of second positioning holes, wherein
the control unit of the robot for attachment further includes an average calculating unit that calculates, based on the detected positions of the plurality of first positioning holes, the average position in the second axial direction of the plurality of first positioning holes and calculates, based on the detected positions of the plurality of second positioning holes, the average position in the fourth axial direction of the plurality of second positioning holes.
