[0020] The present invention sets a turntable mechanism so that a rotating motor can drive the rotating disk to rotate. Through four independent workstations, loading, unloading and processing processes are undisturbed, which greatly shortens the processing time of the piston ring and improves production efficiency. A first telescopic cylinder is set to push the drive box to move on the rotating seat, which is convenient for adjusting the spacing between the ring mounting die sleeve and various mechanisms. The first bevel gear is driven to rotate by the driving motor, thereby driving the second bevel gear meshing with it to rotate, and then the ring mounting die sleeve is driven to rotate by the driving rod, which is used to cooperate with processing and unloading to realize different functions and has high practicality.

[0021] By setting up an external angle polishing mechanism, the first polishing motor drives one of the polishing wheels to rotate, and cooperates with the other polishing wheel to drive the polishing belt to move. The feed cylinder can drive the feed plate to move on the first polishing seat to realize the feeding movement of the polishing belt. The lifting motor drives the screw to rotate, thereby driving the lifting plate to rise and fall on the lifting seat to realize the height adjustment of the polishing belt. The flipping motor drives the first gear to rotate, thereby driving the second gear meshing with it to rotate, and then drives the flipping plate to rotate through the flipping shaft, and adjusts the angle of the polishing belt, thereby realizing multi-directional flexible movement of the polishing belt, so that the polishing belt can polish and chamfer the outer surface of the piston ring, and chamfers of different shapes can be obtained by adjusting the polishing belt, thereby improving the richness of the polishing chamfer.

[0022] By setting up the inner angle polishing mechanism, the second telescopic cylinder drives the rotating cylinder to move on the second polishing seat, the rotating cylinder can drive the third polishing seat on the fixed plate to rotate, and the third telescopic cylinder can drive the second polishing motor to move on the third polishing seat, thereby driving the polishing roller to move to the inside of the piston ring, and the second polishing motor drives the polishing roller to rotate to polish the inner angle of the piston ring, and the shape of the chamfer can be controlled by changing the angle and position of the polishing roller. In addition, with the cooperation of the turntable mechanism, the piston ring is polished by the outer angle polishing mechanism and then rotated to the inner angle polishing mechanism for inner angle polishing, which reduces the steps of multiple clamping of the piston ring in the prior art, greatly reduces the production time, and improves the production efficiency.

[0023] By setting a feeding mechanism, the feeding motor drives the threaded rod to rotate, thereby driving a threaded seat to slide on the slide rail, so that the pushing plate pushes several piston rings on the feeding rod, and pushes the piston ring into the turntable mechanism through the feeding die sleeve with a gradually changing inner diameter, thereby completing the loading; by setting a unloading mechanism, the ring-moving motor drives the rotating rod to rotate, and the connecting plate performs a circular motion under the drive of gravity and the rotating rod, so that the first unloading rod drives the unloading plate to enter the ring-installing die sleeve, and performs a circular motion to hook the piston ring out of the ring-installing die sleeve, and the piston ring slides on the first unloading rod to the ring sorting rod, and the ring sorting motor drives the ring sorting rod to rotate, thereby driving the piston ring to rotate through the friction between the ring sorting rod and the piston ring, so that the notched position of the piston ring faces upward and passes through the connecting plate to fall onto the second unloading rod, thereby completing the unloading process, and the entire loading and unloading process has a high degree of automation, and there is no need for manual loading and unloading, thereby improving production efficiency.

[0045] Working principle:

[0046] When the present invention is in use, the threaded rod 206 is driven to rotate by the feeding motor 205, thereby driving the threaded seat 204 to slide on the slide rail 203, so that the push plate 207 pushes the piston rings on the feeding rod 208, and the piston rings are pushed into the turntable mechanism 3 through the feeding die sleeve 202 with a gradually changing inner diameter, and are clamped in the ring mounting die sleeve 305. The rotating motor can drive the rotating disk 301 to rotate, so that the piston rings rotate to the station of the outer corner polishing mechanism 4;

[0047] The first polishing motor 408 drives one of the polishing wheels 407 to rotate, and cooperates with the other polishing wheel 407 to drive the polishing belt 409 to move. The feed cylinder 403 can drive the feed plate 402 to move on the first polishing seat 401 to realize the feeding movement of the polishing belt 409. The lifting motor drives the screw to rotate, thereby driving the lifting plate 405 to rise and fall on the lifting seat 404 to realize the height adjustment of the polishing belt 409. The flip motor 410 drives the first gear 411 to rotate, thereby driving the second gear 412 meshing therewith to rotate, and then drives the flip plate 406 to rotate through the flip shaft to adjust the angle of the polishing belt 409, so as to realize the multi-directional flexible movement of the polishing belt 409 to the outside of the piston ring for polishing and chamfering, and drives the first bevel gear 308 to rotate through the driving motor 307, thereby driving the second bevel gear 309 meshing therewith to rotate, and then drives the ring mold sleeve 305 to rotate through the driving rod 304, so that the polishing belt 409 can polish and chamfer the outer surface of the piston ring;

[0048] The rotating motor continues to drive the rotating disk 301 to rotate, so that the piston ring rotates to the inner angle polishing mechanism 5 station, and the second telescopic cylinder 507 drives the rotating cylinder 502 to move on the second polishing seat 501, and the rotating cylinder 502 can drive the third polishing seat 504 on the fixed plate 503 to rotate, and the third telescopic cylinder 508 can drive the second polishing motor 505 to move on the third polishing seat 504, thereby driving the polishing roller 506 to move to the inner side of the piston ring, and the second polishing motor 505 drives the polishing roller 506 to rotate to polish the inner angle of the piston ring;

[0049] After polishing, the piston ring rotates to the blanking mechanism 6 station, and the rotating rod 603 is driven to rotate by the ring-moving motor 602. The connecting plate 604 performs a circular motion under the drive of gravity and the rotating rod 603, so that the first blanking rod 605 drives the blanking plate 606 to enter the ring-mounting die sleeve 305, and performs a circular motion to hook the piston ring out of the ring-mounting die sleeve 305. The piston ring slides on the first blanking rod 605 and falls onto the ring sorting rod 609. The ring sorting motor 608 drives the ring sorting rod 609 to rotate, so that the piston ring is driven to rotate by the friction between the ring sorting rod 609 and the piston ring, so that the notched position on the piston ring is upward and passes through the connecting plate 604 and falls onto the second blanking rod 607, completing the blanking process.

[0050] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention.
