First, starting pusher cylinder 24 drives V-arrangement scraping wings 23 to move towards pusher cylinder 24 direction, until piston ring falls
And fall in the V-arrangement locating slot 27 of flitch 25, then, pusher cylinder 24 promotes V-arrangement scraping wings 23, by V-arrangement scraping wings 23
Promote piston ring, make the blind end that piston ring movement positions to V-arrangement, by locating slot 27 by piston ring clamping.
Secondly, start feeding cylinder, feeding slipway, meanwhile, power headstock displacement servo motor are promoted by feeding cylinder
48 drive power headstock slide units 47 to move towards guide rail direction, when the piston ring on the upper flitch 25 of feeding slipway mobile to and power
When piston ring positioner on the headstock 4 is corresponding, drives gripper shoe 210 to rotate by push-and-pull cylinder, so that flitch 25 is overturn
Piston ring can be just right with the location hole on positioning disk 43 afterwards.Then, feeding tumble cylinder 211 promotes upper flitch 25 to overturn, when
Just to rear, feeding throw-out collar cylinder 29 starts location hole on piston ring and positioning disk 43, and piston ring is pushed on positioning disk 43
Positioning in the hole；Meanwhile, magnechuck 42 is energized, and piston ring is tightly adsorbed on positioning disk 43, thus realizing pacifying piston ring
It is attached on the power headstock 4 and position；Afterwards, upper flitch 25 resets, and feeding cylinder drives feeding slipway to return to initial position.
Again, displacement servo motor drives ball wire bar pair to promote processing slide unit 31 mobile, until on processing slide unit 31
Cutter head is corresponding with the medial surface position of piston ring, and at this moment, linear electric motors 35 promote cutter head, until cutter head and piston ring medial surface
Contact, drives piston ring to rotate by the power headstock 4, realizes turnery processing, and in turning process, motor 46 drives central siphon to turn
Dynamic, drive positioning disk 43 and piston ring to rotate by central siphon, meanwhile, power headstock displacement servo motor 48 drives the power headstock to slide
The micro movement of platform 47, thus complete the turnery processing of piston ring angled end-face；After the completion of turnery processing, displacement servo motor passes through rolling
Ballscrew pair continues to press on processing slip and moves, until after emery wheel 34 and piston ring end contact, being driven by grinding motor 33
Emery wheel 34 rotates, simultaneously because the power headstock 4 drives piston ring to rotate, thus realizing the processing of piston ring end face, after machining,
Compound Machining platform 3 return.
Finally, feeding slipway moves towards Compound Machining platform 3 direction after feeding again, when blanking bar 213 and piston ring are just right
When, blanking throw-out collar cylinder 44 is pawled by blanking and is released piston ring, is inserted on blanking bar 213；Then, by rotary cylinder band
Dynamic blanking bar 213 rotates, and when entering the groove 54 on guide post 52 when one end that blanking bar 213 is cased with piston ring, piston ring is slided
Enter guide post 52, and by the guiding movement of guide post 52 to simultaneously sheathed resonable material bar 55 and material stock bar；Now, reason material bar
Rotate under the drive of 55 resonable material motors 56, make the breach of piston ring just right with reason material bar 55, and then make piston ring from reason material bar
Fall on 55, be only enclosed within material stock bar, and along material stock bar movement to the other end of material stock bar.And simultaneously, work on upper flitch 25
, under the drive of feeding slipway, its position is corresponding with the piston ring positioner of the power headstock 4 for plug ring.
Repeat said process, realize piston ring end face and continuously automatically process.
Finally it should be noted that above example is only in order to illustrate technical scheme rather than restriction technologies side
Case, it will be understood by those within the art that, those are modified to technical scheme or equivalent, and
Objective without departing from the technical program and scope, all should cover in the middle of scope of the presently claimed invention.
