[0028] The usage method and advantages of the present invention: When this auxiliary device for installing a micro high-precision bearing is working, the working process is as follows: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, by placing the inner ring inside the auxiliary mounting table 601, then pouring the rolling beads into the auxiliary mounting table 601, under the guiding action of the frustum 605, the rolling beads roll between the inner ring and the telescopic block 604. Then, the inner ring is sleeved outside the abutting column 606. Rotate the support frame 3 to drive the hydraulic telescopic machine 401 to rotate to directly above the abutting column 606, so that the bottom of the pressing block 404 is in movable abutment with the top of the abutting column 606. At this time, the clamping block will insert into the support frame 3 to complete the limit of the support frame 3. Insert the sliding claw 503 into the fitting groove at the bottom of the auxiliary mounting table 601, and complete the positioning of the horizontal height of the sliding claw 503 through the threaded meshing force between the threaded block 505 and the positioning rod 504, to prevent the rotating plate 502 from driving the sliding claw 503 to deflect. Start the hydraulic telescopic machine 401, and the hydraulic telescopic machine 401 pushes the pressing rod 403 downward. The pressing rod 403 pushes the pressing block 404 to push the abutting column 606, so that the inner ring moves towards the direction of the rolling beads and the outer ring. At the same time, the pressing rod 403 drives the linkage rod 405 downward. The linkage rod 405 slides downward in the guiding plate 406 to drive the linkage plate 501 to deflect. When the linkage plate 501 deflects, it will slide on the outer wall of the limiting plate 407. After the linkage plate 501 deflects, it drives the rotating plate 502 and the sliding claw 503 to move upward. Through the opposing force, the inner ring is more smoothly pressed into the rolling beads. After the installation work is completed, the pressing block 404 is reset by the hydraulic telescopic machine 401, and the support frame 3 is rotated to make the pressing block 404 disengage from the top of the abutting column 606. Under the telescopic action of the return spring 603, the return spring 603 pushes the telescopic block 604 upward, so that the telescopic block 604 pushes the frustum 605 and the abutting column 606 upward, and the bearing sleeved outside the abutting column 606 is lifted from the auxiliary mounting table 601 by the frustum 605.
