The course of processing of position, this utility model piston ring automatic milling side mouth device is as follows: the multiple piston rings put in order by opening are successively Being enclosed within link bar 11a, start grinding wheel drive mitor, grinding wheel drive mitor drives emery wheel 5 to rotate, and starts Rapid moving motor 23, quickly Mobile motor 23 promotes slide plate 14 to move quickly into Working position by advance and retreat lead screw assembly 44, and Rapid moving motor 23 stops, Starting motor 18, motor 18 drives worm decelerating machine 17 to rotate, and then drives ball-screw assembly 20 to rotate, left leading screw 25 Rotating, the first nut 55 threadeded with left leading screw 25 is moved to the left, and top cylinder 13, push-plate 12 are moved to the left, and promote a left side The piston ring of end enters ring mould 10, and ball-screw assembly 20 continues to rotate, and promotes the piston ring end face of high order end to be positioned to promote End face limiting plate 8, while ball-screw assembly 20 rotates, screw 1 moves right in nut seat 1, meanwhile, Nut seat two 19b of back pieces pushing block 19 has moved right feeding action, and motor 18 stops；Now, emery wheel swing mechanism leads to Crossing leading screw to drive emery wheel swing to be pointed to the piston ring of high order end to carry out grinding, emery wheel swings forward and swings backward Angle is consistent, machines rear emery wheel and resets, i.e. returns to gap-clearance of piston rings centre position；Start Rapid moving motor 23, quickly Mobile motor 23 drives slide plate 14 to move right by advance and retreat lead screw assembly 44, ring mould 10 regression i.e. ring mould 10 moves right, Link bar 11a regression i.e. moves right, and the piston ring 60 ' that grinding completes comes off, and back pieces adjusting screw 22 clashes into back pieces pushing block 19, back pieces pushing block 19 is moved to the left along slide plate 14, and ball-screw assembly 20 is moved to the left, and top cylinder 13, push-plate 12 are to moving to left Dynamic, the piston ring 60 ' grinding completed is released from ring mould 10, and the piston ring 60 ' that grinding completes comes off and reclaims along workpiece Mechanism 24 flows out, and is through on T-Ring bar 2404 through runner 2401, conveyer mechanism 2402, roller-way 2403, a processing Loop ends.During the next piston ring of processing, circulate said process all the time.

In this utility model, left leading screw 25, the mandrel 26 of worm decelerating machine 17, right leading screw 27 connect as one, left leading screw 25 Identical with the helical pitch of right leading screw 27 and rotation direction, when slide plate 14 moves left and right in the distance set every time back pieces pushing block 19 with The position of back pieces adjusting screw 22 does not changes, and by adjusting the position that back pieces adjusting screw 22 makes piston ring come off after processing Putting and the position of next piston ring to be processed is all constant, each circulation is the flat of the place, ground side with piston ring Face is machining benchmark, can position, automatic milling side mouth, easy and simple to handle, reduce labor intensity and the cost of labor of workman, it is to avoid artificial The opening grinding depth of the piston ring that grinding brings does not waits, polishing width problem not etc., stable and reliable for performance, gives that effect Rate is high, can guarantee that the machining accuracy of piston ring simultaneously.

Embodiment described above is only to be described preferred implementation of the present utility model, not to of the present utility model Scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this utility model The various deformation made of technical scheme and improvement, all should fall in the protection domain that this utility model claims determine.
