A cushioned oil cylinder

Abstract

The utility model relates to hydraulic oil cylinder technical field, concretely relates to a buffer oil cylinder. The utility model discloses a buffer oil cylinder, include: cylinder barrel, the piston of setting in cylinder barrel and with the piston fixed connection piston rod, the one end of piston is away from piston rod is provided with buffer column, clearance ring, clearance ring detachably cover sets up on buffer column, end cover, end cover sets up one end at cylinder barrel, and the one end of end cover is close to piston rod is provided with buffer chamber, buffer column and buffer chamber clearance cooperation, and the center axis of buffer chamber coincides with the center axis of buffer column. The utility model discloses buffer structure including buffer column and buffer chamber through setting, through replacing the clearance ring of different thickness, can change the distance between the inner wall of buffer chamber and the outer wall of clearance ring, can realize the adjustment of clearance channel between buffer column and buffer chamber, and further regulates and control buffer resistance, realizes the adaptation to different load and speed.
