then, the station turntable 1302 continues to rotate, the balance wheel 7011 positioning and clamping device is rotated to the position of the check ring feeding device 3, the check ring 703 is fed, the check ring vibration disc 301 conveys the check ring 703 to the tail end of the second guide track 3011, the positioning column lifting driving piece 30254 drives the positioning column to descend, so that the check ring 703 can pass over the positioning column and enter the check ring positioning seat 30251, then the positioning column lifting driving piece 30254 drives the positioning column to ascend, the positioning column rotating driving piece 30253 drives the positioning column to rotate, so that the positioning column is centrally positioned with the central hole 7031 of the check ring 703, and the positioning column drives the check ring 703 to rotate when rotating until the convex edge of the check ring 703 abuts against the check ring positioning convex part 302513;

next, the check ring 703 is taken, the second translational driving member 3021 drives the second lifting driving member 3022 to move towards the check ring positioning seat 30251, when the second lifting driving member 3022 is in position, the second lifting driving member 3023 drives the second relaxation jaw 3023 to descend, the second relaxation jaw 3023 contracts first and then expands to abut against the inner wall of the central hole 7031 of the check ring 703, so that the check ring 703 is clamped, and when the second relaxation jaw 3023 descends, the positioning column lifting driving member 30254 can drive the positioning column to descend, so that the contact area between the second relaxation jaw 3023 and the check ring 703 is increased;

after the check ring 703 is clamped, the second lifting driving piece 3022 drives the second relaxation jaw 3023 to ascend, the second translation driving piece 3021 drives the second lifting driving piece 3022 to move towards the balance wheel seat positioning and clamping device 2, and after the second lifting driving piece 3022 moves in place, the second relaxation jaw 3023 contracts, so that the check ring 703 is placed on the balance wheel seat positioning and clamping device 2 and positioned;

then, the quantitative conveying component 402 quantitatively takes the fastening screw 704 out, and conveys the fastening screw 704 into the clamping jaw seat through the material guide pipe;

the platform driving assembly 503 drives the moving platform 502 to descend, the moving platform 502 drives the universal transmission shaft 5041 to descend, the screw rod 5042 is screwed to pass through the screw passage 505222, the fastening screw 704 is screwed downwards, the electric screwdriver 504 is rotated, the fastening screw 704 is fastened on the swinging wheel seat 701, and the retainer ring 703 is fixed, so that the assembly of the retainer ring 703 is completed.

After the check ring 703 is installed, the station turntable 1302 rotates the balance wheel seat positioning and clamping device 2 to the blanking device 6, and finally, the balance wheel seat 701 with the check ring 703 installed is blanked through the blanking device 6, so that the process of automatically assembling the check ring 703 of the balance wheel seat 701 is completed, and the automation degree is high.
