摘要

In the preparation step, the frame (10), the concave spherical seat (15), the convex spherical seat (13), the rotating body (16), the swing shaft (12), and the work holder (17) are mutually connected. While assembling, the laser head (33) is attached to the convex spherical seat (13), and the light receiving unit (38) is attached to the work holder (17). In the rotating body centering step, the rotating body (16) is rotated while irradiating the laser irradiation surface (41) with the laser beam (LB) emitted from the laser head (33), thereby rotating the rotating body (41). The irradiation position of the laser beam (LB) is changed, and the locus of the irradiation position is confirmed.
