10. A method of assembling a multi-way microwave rotary joint assembly apparatus according to any one of claims 1 to 7, comprising the steps of:
step one, adjusting equipment, namely adjusting a lifting mechanism (3) to a proper height, adjusting a rotation mechanism (4) to a horizontal position, and arranging rotary joint clamping jaws (6) on a clamp sliding rail (501) to a proper position;
clamping the first group of rotating modules, and clamping and stabilizing the topmost group of rotating modules (201) through a group of rotating joint clamping jaws (6) at the top end of the clamp bracket (5);
step three, preassembling the horizontal posture of the rotating module, enabling the semi-rigid coaxial cable (202) carried by the rotating module (201) clamped in the step two to pass through the inner cavity of a group of the rotating module (201) to be clamped and fixed by the clamping jaw (6), reserving an adjusting gap, temporarily avoiding splicing with the previous group, and binding corresponding holes of the cable limiting disc (503) after carding the semi-rigid coaxial cable (202);
step four, the vertical postures of the rotating modules are accurately butted, the rotating mechanism (4) is adjusted to the vertical postures, and the lifting mechanism (3) is adjusted to the assembling height; aligning an end face sealing ring (203), a radial sealing ring (204) and a transmission shifting fork (205), carding the semi-rigid coaxial cable (202) neatly, loosening clamping jaw locking screws (606), and uniformly pressing down to assemble two groups of double-way rotating modules (201) in place;
and fifthly, repeating the third step and the fourth step to complete the assembly of the multi-path microwave rotary joint (2).
