s6, detecting the spatial position, the misalignment amount and the gap of the melon petal through the matching use of the laser tracker and the detection center platform (6), and correspondingly adjusting the melon petal through the bottom adjusting mechanism (3), the height adjusting mechanism (4) and the top adjusting mechanism (5) when the spatial position, the misalignment amount and the group alignment gap do not accord with set values; when the space position, the misalignment amount and the assembly gap accord with set values, the assembly of the hemispherical melon petal is completed.
9. The high-precision hemispherical melon petal assembly method according to claim 8, characterized in that: in step S1, the lofting position line is detected by the infrared collimator and the laser tracker.
10. The high-precision hemispherical melon petal assembly method according to claim 8, characterized in that: in the step S6, the laser tracker is matched with the detection center platform (6) to detect the sphere diameter of each point position on the inner side of the hemisphere, so that whether the spatial position, the misalignment amount and the pairing gap of the melon petal meet set values or not is judged.
