The two leveling rods 60 are horizontally arranged and symmetrically arranged about the center line of the assembly groove 70. In the specific arrangement, the cylindrical part of the double-headed screw 510 is rotated to pass through the other end side wall of the slide groove 40, and a connecting block is fixedly installed at one end of the double-headed screw 510 to facilitate the rotation of the double-headed screw 510, and the two sliders 520 are slidably arranged in the slide groove 40, and the two sliders 520 are driven to slide by the double-headed screw 510 to realize the movement of the two leveling rods 60, thereby adjusting the distance between the two leveling rods 60.

[0030] When using this application:

[0031] First, place the lower bearing shell in the assembly groove 70 on the bearing seat 10, and then insert the two positioning rods 210 into the two positioning holes 110 respectively, so that the two leveling blocks 220 are in contact with the leveling surface 120 on the top of the bearing seat 10, so that the positioning rod 210 is assembled in place, and then the two horizontal blocks 230 are respectively put on the two positioning rods 210, and the horizontal seat 30 is lifted at the same time. By rotating the double-headed screw 510, the double-headed screw 510 drives the two sliders 520 to slide in the slide groove 40, so that the two sliders 520 drive the two leveling rods 60 to move horizontally, and adjust the two leveling rods 60 to be respectively located above the two ends of the lower bearing shell, and then the horizontal seat 30 can be loosened, so that the two leveling rods 60 are respectively placed on the two end surfaces of the lower bearing shell, and the horizontal seat 30 can be pressed to level the two ends of the lower bearing shell, and finally the two horizontal blocks 230 are removed, and the upper bearing shell can be assembled using existing equipment.
