Abstract
A rotary hydraulic damping balancing device comprises a socket ring with an annular groove, a valve block arranged in the annular groove, and a slewing ring fixedly connected with the valve block. The slewing ring is arranged in the opening of the annular groove, two one-way valves parallel to the tangential direction of the annular groove are arranged in the valve block and are opposite in the communication direction, and a separation rib enabling the annular groove to be disconnected is arranged in the annular groove. The annular groove, the valve block, the slewing ring and the separation rib arranged in the annular groove jointly form a right cavity and a left cavity which are communicated with each other through the two one-way valves. The two one-way valves are of hydraulic unloading structures, so damping balance for work piece motion in rotation in two directions is achieved, the structure is simple, and the effect is reliable.

Technical field
The present invention relates to a kind of damping balance device, especially a kind of revolution hydraulic damping balance device.
Technical background
Mechanical arm, take the rotary mechanism parts such as joint arm of formula coordinatometer, need certain damping in the rotation motion process, steady in order to guarantee the rotation motion process; In addition, when the rotary mechanism parts are turned back to precalculated position, after on it, additional driving torque is cancelled, the rotary mechanism parts need overcome the gravity of himself, can remain on set position, for this reason, the easy motion that needs a kind of damping balance device to guarantee the rotary mechanism parts with and in the fixedly maintenance of operating position, damping balance matching requirements hollow structure, measure components and parts so that design mechanical structure and the layout of rotary mechanism arm simultaneously.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides revolution hydraulic damping balance device a kind of simple in structure, easy to use.
The present invention in order to solve the problems of the technologies described above adopted technological scheme is: a kind of revolution hydraulic damping balance device, comprise the seat ring with annular groove, be arranged on the valve piece in described annular groove, and the pivoted loop be fixedly connected with the valve piece, described pivoted loop is arranged on the notch of annular groove, be provided with two one-way valves that are parallel to the annular groove tangent direction in the valve piece, the conducting direction of two one-way valves is contrary, in annular groove, be provided with one by its disconnection every rib, described annular groove, the valve piece, pivoted loop and be arranged on and form left chamber and the right chamber of intercommunication by two one-way valves every rib is common in annular groove.
Also comprise a pressure ring be arranged between seat ring and pivoted loop, described pressure ring is fixedly connected with seat ring, pressure ring be provided with one with seat ring on the groove that adapts of annular groove, described valve piece is provided with projection, described projection embeds in the groove of pressure ring and is fixedly connected with pivoted loop.
Parallelly on described valve piece be provided with two respectively with the through holes of a cone end, described one-way valve comprises spheroid, Compress Spring and hollow screw, spheroid is arranged on the cone end in described through hole, it is connected with hollow screw by described Compress Spring, and the center line of described through hole, spheroid, Compress Spring and hollow screw coincides.
Beneficial effect: the present invention carries out the structure of hydraulic unloading by two one-way valves, has realized the damping balance of workpiece motion in the revolution of both direction, simple in structure, reliable for effect.
The accompanying drawing explanation

The A-A view that Fig. 2 is Fig. 1.
In figure, 1, seat ring, 101, every rib, 2, the valve piece, 201, through hole, 202, projection, 3, inner ring one-way valve, 301, spheroid, 302, Compress Spring, 303, hollow screw, 4, pivoted loop, 5, left chamber, 6, right chamber, 7, pressure ring, 8, the screw I, 9, the screw II, 10, the outer ring one-way valve.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As shown in the figure, a kind of revolution hydraulic damping balance device, comprise the seat ring 1 with annular groove, be arranged on the valve piece 2 in described annular groove, and the pivoted loop 4 be fixedly connected with by set screw II 9 with valve piece 2, described pivoted loop 4 is arranged on the notch of annular groove, be provided with two inner ring one-way valve 3 and outer ring one-way valves 10 that are parallel to the annular groove tangent direction in valve piece 2, the conducting direction of inner ring one-way valve 3 and outer ring one-way valve 10 is contrary, in annular groove, be provided with one by its disconnection every rib 101, described annular groove, valve piece 2, pivoted loop 4 and be arranged on and form left chamber 5 and the right chamber 6 of intercommunication by two one-way valves 3 every rib 101 is common in annular groove.
In order to reduce the force of sliding friction of valve piece 2 and adjacent elements, and the further sealing effect that improves, a pressure ring 7 is set between seat ring 1 and pivoted loop 4, described pressure ring 7 is used screw I 8 to be fixedly connected with seat ring 1, pressure ring 7 be provided with one with seat ring 1 on the groove that adapts of annular groove, described valve piece 2 is provided with projection 202, and described protruding 202 embed in the groove of pressure rings 7 and are fixedly connected with pivoted loop 4.
Parallelly on described valve piece 2 be provided with two respectively with the through holes 201 of a cone end, described inner ring one-way valve 3 and outer ring one-way valve 10 include spheroid 301, Compress Spring 302 and hollow screw 303, spheroid 301 is arranged on the cone end in described through hole 201, it is connected with hollow screw 303 by described Compress Spring 302, and the center line of described through hole 201, spheroid 301, Compress Spring 302 and hollow screw 303 coincides.
When the present invention works, left chamber 5 and right chamber 6 are filled with hydraulic oil, outer ring one-way valve 10 is opened when pivoted loop 4 clockwise rotates, the hydraulic oil of right chamber 6 flows into to left chamber 5 along with pivoted loop 4 clockwise rotates slowly, inner ring one-way valve 3 is opened when pivoted loop 4 rotates counterclockwise, the hydraulic oil of left chamber 5 flows into along with pivoted loop 4 rotates counterclockwise slowly chamber 6 to the right, because valve piece 2 and pivoted loop 4 are integrally connected, so valve piece 2 moves with pivoted loop 4, thereby makes the rotational speed of workpiece be cushioned.
One-way valve of the present invention has coordinated damping function with the through hole of band cone end, thereby the one-way valve Compress Spring plays the balancing gravity torsional interaction, realizes revolution bidirectional damper and balance.
