2) The assembly shaft seat (5) is matched with the rotary carrying groove (502) to carry out rotary assembly on the two groups of rotary supports (503), and the rotary supports (503) are matched with the threaded grooves (506) and are sleeved on the outer side of one end of the stud (6) through rotation;
3) Simultaneously, the sliding support column (405) is used for sliding assembly of the two groups of locking clamping frames (406), so that the two groups of locking clamping frames (406) are in butt joint, the screwing clamping frames (4061) are clamped on two sides of a locking side groove (505) formed in the rotating support (503), and meanwhile, the threaded side blocks (4062) are matched with the threaded support tube (4063) to lock the two groups of butt-joint locking clamping frames (406);
4) The assembly position of the thread support block (1052) is subjected to positioning comparison through the scale support plate (103), the position of the thread support block (1052) outside the thread support column (1051) is adjusted through rotation, meanwhile, the driving motor (302) is matched with the driving clamping block (303) to drive the rotating support (402) to rotate, and then the rotating shaft frame (4) is synchronously driven to integrally rotate and adjust, so that the screwing clamping frame (4061) can screw a group of rotating supports (503), the other group of rotating supports (503) is matched with the assembly shaft seat (5), the screwed rotating supports (503) can be subjected to limit support, and the rotating supports (503) can synchronously screw sleeved double-end studs (6), so that the lengths of the double-end studs (6) extending out of the end faces of the bearings are adjusted.
