The technical solution used in the present invention is:
The buffer activity platform, 12 connect hinge, buffer fixed platform and six double action single degree of freedom hydraulic buffer; The napex of the bottom of buffer activity platform and buffer fixed platform is separately installed with six and is connected hinge, six on the buffer activity platform connect hinge and connect with the movable cylinder of six double action single degree of freedom hydraulic buffer respectively, other six on the buffer fixed platform connect hinge respectively with the fixedly end cap connection of six double action single degree of freedom hydraulic buffer, connect the layout of hinge on buffer activity platform and buffer fixed platform and be shaped as the hemihedry Hexagon.
Described double action single degree of freedom hydraulic buffer is included in movable end cover is housed in the stationary cylinder, two single-acting single degree of freedom hydraulic buffer are installed at the two ends of stationary cylinder symmetrically, a single-acting single degree of freedom hydraulic buffer is fixed on the right end cap of stationary cylinder, another single-acting single degree of freedom hydraulic buffer is fixed on the left end cap of stationary cylinder, movable cylinder links into an integrated entity with shoulder cylndrical surface, a movable end cover left side after passing left end cap, and another single-acting single degree of freedom hydraulic buffer is positioned at movable cylinder.
The present invention compares with background technique, and the beneficial effect that has is:
The present invention has inherited the advantage of hydraulic cushion, on the basis of double action single degree of freedom hydraulic buffer, adopt 6-dof parallel mechanism, hydraulic buffer of complex vibration has been finished in design, Continuous Tracking can be realized, and, the passive requirement that subtracts vibration isolation of various platforms can be satisfied the hydraulic cushion that sextuple broad sense is vibrated to the controlled device continuous motion, for multi-freedom degree coupled vibrations buffer system provides Integrated Solution a kind of compactness, desirable, be breakthrough to the conventional hydraulic buffer.And characteristics such as cushion effect is big because 6-dof parallel mechanism has, mechanism's good rigidity, response are fast make the present invention have better shock-absorbing capacity index, can obtain better test effect.The present invention can be widely used in various multidimensional power buffer structures, and the coupled vibrations of platform subtracts in the vibrating isolation system, have important real value to promoting equipment preparations such as the high performance hydraulic bjuffer of China, platform stable system, development China industrial production, national economy and national defense and military construction are played an important role.

Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
1, ten two on buffer activity platform connects hinge 2, buffer fixed platform 3 and six double action single degree of freedom hydraulic buffer 4.The top of the bottom of buffer activity platform 1 and buffer fixed platform 3 is separately installed with six and is connected hinge 2, six on the buffer activity platform 1 connect hinge and connect with the movable cylinder of six double action single degree of freedom hydraulic buffer 4 respectively, other six on the buffer fixed platform 3 connect hinge 2 respectively with fixedly end cap 12 connections of six double action single degree of freedom hydraulic buffer 4, connect the layout of hinge 2 on buffer activity platform 1 and buffer fixed platform 3 and be shaped as the hemihedry Hexagon.
Described double action single degree of freedom hydraulic buffer 4 comprises: movable end cover 10 is housed in stationary cylinder 8, two single-acting single degree of freedom hydraulic buffer 13 are installed at the two ends of stationary cylinder 8 symmetrically, a single-acting is fixed on the right end cap 12 of stationary cylinder 8, fastening by attaching nut 6, another single-acting single degree of freedom hydraulic buffer 13 is fixed on the left end cap 7 of stationary cylinder 8, fastening by another one attaching nut 6, movable cylinder 5 passes left end cap 7 backs and links into an integrated entity with movable end cover 10 left shoulder cylndrical surface, another single-acting single degree of freedom hydraulic buffer 13 is positioned at movable cylinder 5, two piston rod embeds the two ends of movable end cover 10 respectively, and be located by connecting by tightening screw 11, this single-acting single degree of freedom hydraulic buffer 13 can use market product of the same type, also can freely design according to actual conditions.
Working principle:
Buffer activity platform 1 is by the logical controlled device connection of peripheral linkage structure, and buffer fixed platform 3 connects with support or other fixed pan, and six double action single degree of freedom hydraulic buffer 4 connect and support buffer activity platform 1 by connecting hinge 2.What the present invention adopted on the whole is six-degree-of-freedom structure in parallel, and buffer activity platform 1 can be finished along the straight line motion of coordinate X, Y, Z axle and around coordinate X, Y, Z axle tumbling motion.
With the base plane is the coordinate XOY plane, coordinate Z axle postive direction upwards, when controlled device when Z axle postive direction is moved, buffer activity platform 1 moves upward, by connecting 2 six double action single degree of freedom hydraulic buffer 4 tensions of hinge, the movable cylinder 5 of double action single degree of freedom hydraulic buffer 4 moves upward, and pulling movable end cover 10 moves upward, piston rod 9 pressurizeds of the single-acting single degree of freedom hydraulic buffer 13 that links to each other with left end cap 7, this hydraulic bjuffer plays buffer function.When controlled device when Z axle negative direction is moved, buffer activity platform 1 moves downward, by connecting 2 six double action single degree of freedom hydraulic buffer 4 pressurizeds of hinge, the movable cylinder 5 of double action single degree of freedom hydraulic buffer 4 moves downward, pulling movable end cover 10 moves downward, piston rod 9 pressurizeds of the single-acting single degree of freedom hydraulic buffer 13 that links to each other with right end cap 12, this hydraulic bjuffer plays buffer function.
When controlled device along coordinate X, Y-axis straight line motion, or when X, Y, Z axle tumbling motion, three double action single degree of freedom hydraulic buffer 4 tensions, other three double action single degree of freedom hydraulic buffer 4 pressurizeds, its hydraulic cushion process is similar with above-mentioned description.
