Beneficial effect：The hydraulic bjuffer that the utility model is provided, the cushion dashpot of original mechanism is divided into two layers, one layer solid
Fixed, one layer of rotation, there is the throttle orifice of different numbers and size in each face of motion cushion dashpot, and fix cushion dashpot only has in a face
One cribbing discharge orifice, by rotational motion cushion dashpot, allows the throttling hole count on its surface to be alignd with the throttling hole count of fixed cushion dashpot, from
And realize that buffer uses the throttle orifice of different numbers in varied situations, cushion effect reaches variable effect.It is slow by changing
Break through throttling hole count that journey uses to reach the effect of regulation cushion effect, cushion effect can be adjusted according to the difference of actual conditions
Size, select most suitable buffering effect, maximize the performance of mechanism.Due to the flow restriction of throttle orifice, the speed of piston
Degree is restricted, and reaches the effect of buffering, passes through cushion dashpot in hydraulic bjuffer（Motion）Rotation, adjust throttle orifice knot
Structure, so that the cushion effect of this buffer is adjustable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural model of cushion dashpot in the utility model；
In figure：Oil cylinder seat 1, cushion dashpot 2, fixed cushion dashpot 21, motion cushion dashpot 22, piston 3, rotary sleeve 4, throttle orifice 5,
Return port 6, inner chamber 7, exocoel 8.
Embodiment
The utility model is further described with reference to specific embodiment.
As shown in figure 1, a kind of hydraulic bjuffer, including oil cylinder seat 1, cushion dashpot 2, piston 3, rotary sleeve 4；Cushion dashpot 2 is consolidated
It is scheduled in oil cylinder seat 1, the cushion dashpot 2 includes fixed cushion dashpot 21 and motion cushion dashpot 22；Fixed cushion dashpot 21 is set in fortune
The inside of dynamic cushion dashpot 22, fixed cushion dashpot 21 and motion cushion dashpot 22 correspondence position surface offers throttle orifice 5 and return port
6, the fixed cushion dashpot 21 is hollow container, for storing fluid, fixed cushion dashpot 21 and the hollow space of the formation of piston 3
For inner chamber 7；There is certain gap between motion cushion dashpot 22 and oil cylinder seat 1, the gap uses to form exocoel 8 as oil back chamber；
Rotary sleeve 4 is connected with motion cushion dashpot 2, and for controlling the rotation for moving cushion dashpot 2, regulation motion cushion dashpot 22 is buffered with fixed
The number of throttle orifice 5 and size that cylinder 21 aligns；When piston 3 is moved by the effect of power into cushion dashpot, fluid compressed from
Inner chamber 7 flows to exocoel 8 through throttle orifice 5, then flows back to inner chamber by return port 6, to realize the circulation of fluid.
Described hydraulic bjuffer, piston 3 includes piston head and is connected to the piston rod on piston head top, and piston head is set
Make to fix the sealing of the top of cushion dashpot 21 inside fixed cushion dashpot 21.
In the present embodiment, the rotary sleeve 4 sets the top for being connected to motion cushion dashpot 2.
Preferably, throttle orifice is arranged on the middle and lower part of cushion dashpot, and return port is arranged on top to the top of cushion dashpot
The position at end.
Fig. 2 show the structural model of cushion dashpot 2, and top is return port 6, and bottom is throttle orifice 5, moves the He of cushion dashpot 22
The difference of fixed cushion dashpot 21 is that there are throttle orifice, and number in the four sides of motion cushion dashpot 22, and fixes cushion dashpot
21 are only to have throttle orifice in one side, and the throttle orifice for causing two cushion dashpots by rotary motion cushion dashpot aligns, due to difference
In face of it is neat when, the number of the throttle orifice played a role is different so that the buffering effect of cushion dashpot is different.Simultaneous buffering device due to
, can be the throttle orifice relative dislocations of two cushion dashpots so that effective throttleng surface when the reasons such as oil leak cause the shock-absorbing capacity to decline
Product reduces, and cushion effect becomes big, plays certain adjustment effect.
The utility model is as follows using process：Before work, injecting oil liquid in inner chamber 7, when piston by power effect to slow
Rush when being moved in cylinder, the throttle orifice 5 of fluid from motion cushion dashpot 22 and fixed both UNICOMs of cushion dashpot 21 flows out, and is left to exocoel
8, buffering effect is reached by the flow restriction of throttle orifice 5, and the fluid in exocoel is flowed back in inner chamber by return port 6.From stream
The angle analysis of mechanics understands that the main structure parameters of influence buffer buffering effect have hole count, aperture and the coordinate in hole.Change
The number of variable orifice can realize the regulation of cushion effect, tackle different situations.
Described above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
