[0026] Since the milling part 5 needs to be in a vertical state when the milling part 5 is milled, the part mounting member 22 is initially arranged vertically. Figure 1 As shown, first, the power transmission mechanism works to rotate the part mounting member 22 counterclockwise by 90°, so that the part mounting member 22 is arranged horizontally, as shown in FIG. Figure 2 Then the hydraulic cylinder 3 works, causing its piston rod to retract downward, so that the part mounting member 22 moves downward to a specified position, such as Figure 3 As shown, after the parts mounting and hanging member 22 moves downward into position, the worker mounts and hangs the milling part 5 on the parts mounting and hanging member 22 as shown in FIG. Figure 6 As shown; then the hydraulic cylinder 3 works, so that its piston rod extends upward, so that the parts mounting and hanging part moves upward with the milling part 5 to the specified position; finally, the power transmission mechanism works to rotate the parts mounting and hanging part 22 clockwise by 90 degrees, so that the parts mounting and hanging part 22 is set vertically, thereby completing the mounting and hanging work of the milling part 5. After the milling part 5 is mounted and hung, the crane hoists the flying target assembly 2 and the milling part 5 to the milling process for processing.
