Description
Technical field
The utility model relates to technical field of hydraulic pressure, particularly relates to the permanent throttling buffering mechanism of a kind of oil hydraulic cylinder.
Background technique
The end of travel damping mechanism of oil hydraulic cylinder can make the piston element of band dynamic load decelerate to zero when arriving end of travel, object eliminates the mechanical impact between piston because inertial force and the hydraulic coupling of piston element causes and end cap, simultaneously also in order to reduce the piston noise that liquid sends when changing moving direction.Existing damping mechanism can produce fever phenomenon, and piston is when terminal, and oil hydraulic cylinder two chamber communicates, and has certain influence for reverse starting.
Model utility content
According to above deficiency, the utility model provides that a kind of processing cost is low, compact structure and the permanent throttling buffering mechanism of the oil hydraulic cylinder of reliable in action.
For achieving the above object, the permanent throttling buffering mechanism of the utility model oil hydraulic cylinder, main contents are: comprise cylinder barrel, piston, cylinder cap, cone shaped spring, throttle orifice, buffer stopper, shaft block ring and piston rod, it is characterized in that, described cylinder cap is connected as a single entity by welding and cylinder barrel and is positioned on the right side of cylinder barrel, described piston is arranged on inner hole of cylinder, described piston and inner hole of cylinder junction are provided with seal ring, described piston rod right-hand member is arranged in piston left end tapped hole by screw thread, throttle orifice is processed with in described piston right-hand member cylinder shape groove, described buffer stopper left end is fixedly mounted in piston right-hand member endoporus, described shaft block ring to be arranged in buffer stopper left end draw-in groove and to be positioned on the left of bottom surface, piston thread hole, described cone shaped spring is arranged on the bottom surface that on buffer stopper axle and its left side withstands on piston right-hand member groove, described cone shaped spring right side withstands on buffer stopper major part left side.
As preferably, described piston rod central position is axially processed with endoporus.
As preferably, described buffer stopper central position is axially processed with oil inlet hole.
As preferably, it is interference fit that described buffer stopper left end shaft and piston are installed between endoporus, is Spielpassung between piston and inner hole of cylinder.
As preferably, in described buffer stopper left end shaft, radial position is processed with groove.
The utility model beneficial effect is: have larger lateral stability; Compact structure, saves the transverse dimension of conventional buffer plunger, decreases cushion stroke; Structure is simple, excellent processability; Cost is low.

Embodiment
Below in conjunction with drawings and Examples, the utility model embodiment is described:
These system main contents are: comprise cylinder barrel 1, piston 2, cylinder cap 3, cone shaped spring 4, throttle orifice 5, buffer stopper 6, shaft block ring 7 and piston rod 8, it is characterized in that, described cylinder cap 3 is connected as a single entity by welding and cylinder barrel 1 and is positioned on the right side of cylinder barrel 1, described piston 2 is arranged on cylinder barrel 1 endoporus, described piston 2 is provided with seal ring with cylinder barrel 1 endoporus junction, described piston rod 8 right-hand member is arranged in piston 2 left end tapped hole by screw thread, throttle orifice 5 is processed with in described piston 2 right-hand member cylinder shape groove, described buffer stopper 6 left end is fixedly mounted in piston 2 right-hand member endoporus, described shaft block ring 7 to be arranged in buffer stopper 6 left end draw-in groove and to be positioned on the left of piston 2 tapped hole bottom surface, described cone shaped spring 4 is arranged on the bottom surface that on buffer stopper 6 axle and its left side withstands on piston 2 right-hand member groove, described cone shaped spring 4 right side withstands on buffer stopper 6 major part left side.
It is interference fit that described buffer stopper 6 left end shaft and piston 2 are installed between endoporus, is Spielpassung between piston 2 and cylinder barrel 1 endoporus.
Described mechanism when piston 2 moves to cylinder cap 3 direction, buffer stopper 6 under the effect of shaft block ring 7 and cone shaped spring 4 also along with piston 2 moves to cylinder cap direction; When buffer stopper 6 and cylinder cap 3 Planar Compound, form buffering oil pocket in rodless cavity, the fluid be closed can only be discharged from throttle orifice 5, thus realizes permanent throttling buffering.
By reference to the accompanying drawings the utility model preferred implementation is explained in detail above, but the utility model is not limited to above-mentioned mode of execution, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific mode of execution, scope of the present utility model is defined by the following claims.
