Embodiment
The adjustable hydraulic damping buffering device is by oil cylinder housing 1, piston rod 2, intermediate sleeve 3, regulating sleeve 4 and plug-in unit
Plug 5 is formed;The top of oil cylinder housing 1 is sealed and installed with end cap 11, and oil cylinder housing 1 is interior to be provided with piston rod 2 by big spring 6,
The bottom layer of piston rod 2 is stacked to be provided with reducing flange 7, and reducing flange 7 is slidingly sealed with the inwall of oil cylinder housing 1 and is connected;Thus
The inner chamber of oil cylinder housing 1 is separated into the shoe cream room 8 on top and the working chamber 9 of bottom;Layered laminate is uniform on the circumference of reducing flange 7
There are multiple flowing holes 10.Keyway 13 is evenly equipped with the circumference of piston rod 2 of the top of reducing flange 7, the piston rod 2 of the top of keyway 13 is justified
Screw thread 14 is provided with week.
One end of piston rod 2 extends to the top of oil cylinder housing 1 through end cap 11, extends to the piston of the top of oil cylinder housing 1
Regulating sleeve 4 is provided with by screw thread on bar 2, swing handle 19 is fixed with regulating sleeve 4.The piston of the lower section of regulating sleeve 4
Intermediate sleeve 3 is slidably fitted with bar 2, intermediate sleeve 3 is slidingly sealed with end cap 11 and is connected.The piston rod 2 of the lower section of intermediate sleeve 3
It is upper that plug-in unit plug 5 is slidably fitted with by little spring 12;Pad 18 is provided between intermediate sleeve 3 and inserted link plug 5.
Plug-in unit plug 5 is made up of mounting disc 15 and inserted link 16, and the centre of mounting disc 15 is provided with pilot hole, pilot hole
Upper symmetry shape is provided with feather key 17;The quantity of feather key 17 is corresponding with keyway 13, the cooperation that plug-in unit plug 5 passes through feather key 17 and keyway 13
It is slidably connected with piston rod 2.Multiple inserted links 16 are fixed with the lower surface of mounting disc 15 of pilot hole periphery;Each inserted link 16 is isometric,
The quantity of inserted link 16 is corresponding with the quantity of flowing hole 10;Plug-in unit plug 5 is connected by inserted link 16 and the insertion of flowing hole 10.
During the adjustable hydraulic damping buffering device work, external agency, external agency can be connected by the upper end of piston rod 2
Impact or vibration transmitted downwards by the upper end of piston rod 2.Stopper rod 2 moves up and down while still alive during this, in piston rod 2 to moving down
In dynamic process, because the flowing hole 10 on reducing flange 7 is in be stacked, and inserted link 16 is isometric, and piston rod 2 moves down simultaneously
During compressing plug-in unit plug 5 is descending, the inserted link 16 of plug-in unit plug 5, which is successively inserted into flowing hole 10, forms closure, simultaneously
During piston rod 2 moves down, reduced with the quantity of flowing hole 10, fluid is flowed into the mistake of shoe cream room 8 in working chamber 9
Flow diminishes, and the fluid in working chamber 9 is squeezed, and enters oil storage by the flowing hole 10 on the bottom reducing flange 7 of piston rod 2
Chamber 8;During this, downward movement of the fluid to piston rod 2 produces recoil inhibition, i.e. cushioning effect.And the recoil
Inhibition changes from small to big with successively insertion of the inserted link 16 to flowing hole 10, while coordinates big spring 6, so as to realize to piston
The buffering of bar 2, and then realize the buffering to external agency.Piston rod 2 and plug-in unit plug 5 after external agency's impact or vibration disappearance
Resetted respectively in the presence of big spring 6 and little spring 12.
The adjustable hydraulic damping buffering device can move down regulating sleeve 4 by rotating clockwise swing handle 19, and
Promote plug-in unit plug 5 to move down by extruding intermediate sleeve 3 and pad 18, sealed so as to be formed by inserted link 16 to flowing hole 10
It is stifled;Because the flowing hole 10 on reducing flange 7 is in be stacked, and inserted link 16 is isometric, and the lower amount of movement of plug-in unit plug 5 is different,
The quantity that inserted link 16 inserts flowing hole 10 is different;So as to cause amount of resistant different.Such as:All flowing holes 10 are all in open shape
State, now the damping of the buffer unit is minimum;Rotate clockwise swing handle 19, regulating sleeve 4 move down promote plug-in unit plug 5 to
Lower movement, until all inserted links 16 insertion flowing hole 10, i.e., all flowing holes 10 are blocked;Now the buffer unit can not play
The effect of buffering.
Rotating counterclockwise and rotate handle 19, regulating sleeve 4 moves up, and in the presence of little spring 12, plug-in unit plug 5 moves up,
Flowing hole 10 successively opens, and damping, i.e. recoil inhibition now is as inserted link 16 is to the successively open by big of flowing hole 10
Diminish.
The buffer unit structure is simple, practicality is good, and shoe cream room is flowed into by the fluid of the adjustment work chamber 9 of swing handle 19
8 area of passage, so as to adjust the resistance that fluid gives piston rod 2, that is, it have adjusted the damping of the buffer.Solve existing slow
The damping for rushing device be immobilize it is uncontrollable, when operating mode changes, buffer also need therewith change not only wastes
Time, and the problem of reduce economic benefit;To protection equipment, the service life of extension device, and noise is reduced, improved
Working environment has positive meaning.
