The utility model solves the technological scheme that its technical problem adopted: a kind of cushion cylinder of big cylinder diameter can regulate cushioning effect; Comprise cylinder body, piston rod and piston; The bottom of cylinder body has bottom, and described piston is provided with damping device towards an end of bottom, and described damping device comprises the hollow cylinder that is fixedly connected with piston; Described hollow cylinder is an opening towards an end of bottom, and the side of hollow cylinder offers through hole; Described damping device also comprises buffering sliding sleeve that is used for through hole on the closed hollow cylinder and the elastic member that is used to the buffering sliding sleeve is resetted; Described elastic member one end is fixedly connected with piston; Described snubber slide cover is placed in outside the hollow cylinder, and buffering sliding sleeve and hollow cylinder size are complementary; Described bottom offers the groove that cooperates with damping device, and described groove and hollow cylinder size are complementary, and is provided with the countercheck mechanism that is used to limit buffering sliding sleeve stroke in the groove.
Fix with piston for ease, as preferably, described hollow cylinder is the cup of an end opening, is connected with piston thread at the bottom of the cup cup.
Damage the contact position with piston in order to prevent to cushion sliding sleeve, described piston is provided with cushion pad towards an end of bottom, and when snubber slide cover compression elastic member and an end during near piston base, cushion pad is connected with an end in contact that cushions sliding sleeve.
In order to guarantee that countercheck mechanism limits the buffering sliding sleeve, the contacted end outer surface of described buffering sliding sleeve and countercheck mechanism is provided with flange.
As a kind of optimal way, described groove comprises the bottom land part that is complementary with hollow cylinder, and with the slot-open-section that is complementary of buffering sliding sleeve, form step between described bottom land part and the slot-open-section, described step is a countercheck mechanism.
In order to prevent that cushioning sliding sleeve breaks away from hollow cylinder, a kind of mode is that described hollow cylinder is provided with the rib that is used to prevent to cushion sliding sleeve disengaging hollow cylinder towards an end outer surface of bottom; Another kind of mode is that the other end of described elastic member is fixedly connected with the buffering sliding sleeve.
The beneficial effect of the utility model is; The cushion cylinder of the big cylinder diameter can regulate of the utility model cushioning effect; The through hole of on hollow cylinder, processing as required after snubber slide is enclosed within and runs into bottom, is progressively closed the through hole on the hollow cylinder; Thereby reach the outflow flow that progressively reduces piston base fluid, avoid the piston slap cylinder bottom; Can be widely used on the oil cylinder of big specification, the part of buffering can be processed in the standardization numerical control, and is more accurately reliable; And cushioning effect can be regulated, and increases the reliability that oil cylinder uses, and has reduced service cost, when reality is debugged, can regulate cushioning effect through increasing and reduce aperture.
