Then, the quantitative conveying component 402 quantitatively takes out the fastening screw 904, and conveys the fastening screw 904 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 screwing rod 5042 passes through the screw passing channel 505222 to bring down the fastening screw 904, the electric screwdriver 504 rotates, and accordingly the fastening screw 904 is fastened on the balance wheel base 901 and the retainer ring 903 is fixed, and therefore assembly of the retainer ring 903 is completed;

The station turntable 1702 continues to rotate, the balance 9011 positioning and clamping device rotates to the position where the eccentric cam feeding device 6 is located, the inclined eccentric cam 905 is fed, the eccentric cam vibration disc 601 conveys the inclined eccentric cam 905 to the tail end of the fourth material guide rail 6011 and onto the positioning seat 6031 along the positioning guide groove 60311, the eccentric cam clamping cylinder 6022 drives the clamping piece 60221 to clamp the inclined eccentric cam 905, the main limiting cylinder 6032 and the auxiliary limiting cylinder 6033 shrink, so that the limit on the inclined eccentric cam 905 is released, the overturning cylinder 6021 integrally rotates the eccentric cam clamping cylinder 6022, the inclined eccentric cam 905 overturns, and the inclined eccentric cam 905 is placed in the inner ring of the bearing 902 of the balance seat positioning and clamping device 2, and the inner ring of the bearing 902 can keep the inclined eccentric cam 905 in an upright state because a space is kept between the auxiliary positioning piece 203 and the upper surface of the inner ring of the bearing 902.

Then, the station turntable 1702 rotates to the first wing plate, the clamping structure 202 is opened, then the jacking driving member 20 drives the jacking member 19 to ascend until the distance from the top of the jacking member 19 to the lower surface of the clamp body 201 is 1 mm-2 mm, next, the press-fit driving member 703 drives the press-fit rod 701 to descend, the universal press-fit head 702 at the end of the press-fit rod 701 abuts against the upper surface of the inclined eccentric cam 905, and when the universal press-fit head 702 abuts against the inclined eccentric cam 905 to move downwards, the clamp body 201 moves downwards, and the second reset elastic member can buffer pressure and reduce the impact on the station turntable 1702.

Because the universal press-fitting head 702 can freely rotate, the lower surface of the universal press-fitting head 702 can be fully contacted with the upper surface of the inclined eccentric cam 905, the lifting direction of the press-fitting rod 701 coincides with the central line direction of the balance wheel seat 901, namely, the lifting direction of the press-fitting rod 701 coincides with the axis of the bearing 902 on the balance wheel seat 901, when the universal press-fitting head 702 is driven to press the inclined eccentric cam 905 by the descending of the press-fitting rod 701, the universal press-fitting head 702 applies uniform vertical downward pressure to the inclined eccentric cam 905 in a surface-to-surface contact manner, so that the press-fitting of the inclined eccentric cam 905 is stable, the press-fitting quality is improved, the press-fitting can be carried out in place once, and the production efficiency is high.

After the pressing of the tilting eccentric cam 905 is completed, the first reset elastic piece applies elastic force to the auxiliary positioning piece 203, the auxiliary positioning piece 203 is abutted with the bottom of the tilting eccentric cam 905 in the bearing 902, so that the pressed balance wheel seat 901 is separated from the balance wheel seat positioning and clamping device 2, and finally, the process of automatically pressing the tilting eccentric cam 905 of the balance wheel seat 901 is completed by blanking the check ring 903 and the pressed balance wheel seat 901 through the blanking device 8, and the degree of automation is high.
