The invention relates to ring opening stirring, arranging and step
polishing equipment. The ring opening stirring, arranging and step
polishing equipment comprises a beveling
machine, an automatic arranging device, an opening
polishing device and an opening step polishing part, wherein the automatic arranging device is arranged at the material outlet of the beveling
machine, and used for orderly arranging beveled
piston rings in a line according to the respective beveled parts; the opening polishing device is arranged at the rear end of the automatic arranging device, and used for polishing the openings of the orderly arranged
piston rings; the opening step polishing part is arranged at the rear end of the opening polishing device, and used for step polishing at the openings of the
piston rings; the automatic arranging device comprises a rotary material stirring
brush arranged on the beveling
machine, a material rod, and a material blocking arranged at the
tail end of the material rod; and the material rod extends outward from the material outlet of the beveling machine and inclines downward. By adoption of the ring opening stirring, arranging and step polishing equipment, the problems that in the prior art, relatively high manpower consumption is needed for arrangement of the beveled piston rings according to the respective beveled parts, the piston rings are easy to damage because several automated arranging units run unstably, the opening polishing efficiency is low after the arrangement, the polishing equipment structure is complex, the
failure rate is high, and automated high-efficiency opening step polishing is unachievable can be solved.
