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 tightening rod 5042 penetrates through the screw passing channel 505222, the fastening screw 904 is screwed downwards, the electric screwdriver 504 rotates, the fastening screw 904 is fastened on the swinging wheel seat 901 and the retainer ring 903 is fixed, and therefore the assembly of the retainer ring 903 is completed;
the station turntable 1702 continues to rotate, the balance wheel 9011 positioning and clamping device is rotated to the position of the eccentric cam feeding device 6, the eccentric cam 905 is tilted for feeding, the eccentric cam vibrating disc 601 conveys the tilted eccentric cam 905 to the tail end of the fourth 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 tilted eccentric cam 905, the main limit cylinder 6032 and the auxiliary limit cylinder 6033 contract, thereby releasing the limit of the inclined eccentric cam 905, the turnover cylinder 6021 rotates the eccentric cam holding cylinder 6022 as a whole, thereby, the inclined eccentric cam 905 is turned over, and the inclined eccentric cam 905 is placed in the inner race of the bearing 902 of the balance holder 901 of the balance holder setting and clamping device 2, since the auxiliary spacer 203 is spaced apart from the upper surface of the inner race of the bearing 902, the inner race of the bearing 902 can maintain the inclined eccentric cam 905 in an upright state.
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 between the top of the jacking member 19 and the lower surface of the clamp body 201 is 1 mm-2 mm, next, the press-fitting driving member 703 drives the press-fitting rod 701 to descend, the universal press-fitting head 702 at the end of the press-fitting rod 701 abuts against the upper surface of the inclined eccentric cam 905, when the universal press-fitting head 702 abuts against the inclined eccentric cam 905 to move downwards, the clamp body 201 moves downwards, the second reset elastic member can buffer pressure, and impact on the station turntable 1702 is reduced.
Because the universal press-fitting head 702 can freely rotate, the lower surface of the universal press-fitting head 702 can fully contact with the upper surface of the inclined eccentric cam 905, and the lifting direction of the press-fitting rod 701 coincides with the direction of the center line of the balance wheel seat 901, that is, the lifting direction of the press-fitting rod 701 coincides with the axis of the bearing 902 on the balance wheel seat 901, so that when the press-fitting rod 701 descends to drive the universal press-fitting head 702 to press the inclined eccentric cam 905 downwards, the universal press-fitting head 702 applies uniform vertical downward pressure to the inclined eccentric cam 905 in a surface-to-surface contact mode, so that the inclined eccentric cam 905 is pressed stably, the press-fitting quality is improved, the press-fitting can be pressed in place at one time, and the production efficiency is high.
After the inclined eccentric cam 905 is pressed, the first reset elastic element applies elastic force to the auxiliary positioning element 203, the auxiliary positioning element 203 is abutted against the bottom of the inclined eccentric cam 905 in the bearing 902, so that the balance wheel seat 901 after being pressed is separated from the balance wheel seat positioning and clamping device 2, finally, the balance wheel seat 901 after the check ring 903 is installed and the inclined eccentric cam 905 is pressed is blanked by the blanking device 8, and the process of automatically pressing the inclined eccentric cam 905 of the balance wheel seat 901 is completed, so that the automation degree is high.
Example two
The embodiment discloses an automatic assembly process of an eccentric cam and a check ring of a three-cam seat, which is based on the automatic assembly equipment of the eccentric cam and the check ring of the three-cam seat, and comprises the following steps:
s1: the balance wheel seat feeding device feeds materials, the balance wheel seat is conveyed to the balance wheel seat positioning and clamping device, and the balance wheel seat positioning and clamping device positions and clamps the balance wheel seat;
s2: feeding the retainer ring by a retainer ring feeding device, conveying the retainer ring to a balance wheel seat positioning and clamping device, and positioning and clamping the retainer ring by the balance wheel seat positioning and clamping device;
s3: the screw feeding device feeds materials, and fastening screws are quantitatively conveyed to the screw screwing device;
s4: the screw screwing device fastens a fastening screw on the balance wheel seat positioning and clamping device and fixes the check ring;
s5: the eccentric cam feeding device feeds the inclined eccentric cam to the balance wheel seat positioning and clamping device, and the inclined eccentric cam is positioned to the bearing inner ring of the balance wheel seat on the balance wheel seat positioning and clamping device;
s6: the eccentric cam press-mounting device presses the inclined eccentric cam into the bearing inner ring;
s7: the discharging device takes the balance wheel seat assembled with the inclined eccentric cam and the retainer ring down from the balance wheel seat positioning and clamping device for discharging.
The process is repeated, the automatic feeding and assembling process of the swinging wheel seat, the check ring, the fastening screw and the inclined eccentric cam can be realized, the automation degree is high, the labor intensity of production is reduced, and the production efficiency is improved.
