Rubber circle car limit equipment

The utility model discloses a rubber circle car limit equipment, including rubber circle chuck, chuck clamping mechanism, frame and cutting mechanism. Chuck clamping mechanism and cutting mechanism install in the frame, and unprocessed rubber ring is on rubber circle chuck, and rubber circle chuck is installed on chuck clamping mechanism, and chuck clamping mechanism rotates through drive arrangement drive, and cutting mechanism drives through the 2nd actuating mechanism and processes the rubber circle. Rubber circle chuck includes endotheca and outer tube, and endotheca and outer tube pass through the taper thread connection that the tapering is 2 degrees to 4 degrees, and sees from the great one end of internal thread end mouth that the outer tube evenly is cut into at least three, and these piecemeals are at the end -to -end connection of outer tube. With endotheca precession outer tube, at the precession in -process, outer tube micro deformation, inflation to fix the rubber circle that overlaps in its out
