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.
Description
Technical field
The present invention relates to a kind of damping balance device, especially a kind of revolution hydraulic damping balance device.
Technical background
The rotary mechanism parts such as mechanical arm, the joint arm taking formula coordinatometer, need certain damping in rotation motion process, steady in order to ensure rotation motion process; In addition, when rotary mechanism parts are turned back to precalculated position, after driving torque additional on it is cancelled, rotary mechanism parts need overcome himself gravity, can remain on set position, for this reason, need a kind of damping balance device to ensure easy motion and its maintenance at fixing operating position of rotary mechanism parts, damping balance matching requirements hollow structure simultaneously, so that the mechanical structure of design turn-around machine mechanical arm and layout measure components and parts.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of structure simple, revolution hydraulic damping balance device 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 block in described annular groove, and the pivoted loop to be fixedly connected with valve block, described pivoted loop is arranged on the notch of annular groove, the one-way valve that two are parallel to annular groove tangent direction is provided with in valve block, the conducting direction of two one-way valves is contrary, be provided with in annular groove one disconnected every rib, described annular groove, valve block, pivoted loop and be arranged on jointly being formed by two one-way valves and the left chamber of intercommunication and right chamber every rib 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 is provided with a groove adapted with annular groove on seat ring, and described valve block is provided with projection, described projection embed pressure ring groove in and be fixedly connected with pivoted loop.
On described valve block parallel be provided with two respectively with one cone end through hole, 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.

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 block 2 in described annular groove, and the pivoted loop 4 to be fixedly connected with by set screw II 9 with valve block 2, described pivoted loop 4 is arranged on the notch of annular groove, inner ring one-way valve 3 and outer ring one-way valve 10 that two are parallel to annular groove tangent direction is provided with in valve block 2, the conducting direction of inner ring one-way valve 3 and outer ring one-way valve 10 is contrary, be provided with in annular groove one disconnected every rib 101, described annular groove, valve block 2, pivoted loop 4 and be arranged on and jointly form by two one-way valves 3 left chamber 5 of intercommunication and right chamber 6 every rib 101 in annular groove.
In order to reduce the force of sliding friction of valve block 2 and adjacent elements, and improve sealing effect further, a pressure ring 7 is set between seat ring 1 and pivoted loop 4, described pressure ring 7 and seat ring 1 use screw I 8 to be fixedly connected with, pressure ring 7 is provided with a groove adapted with annular groove on seat ring 1, described valve block 2 is provided with protruding 202, and described protruding 202 to embed in the groove of pressure rings 7 and to be fixedly connected with pivoted loop 4.
On described valve block 2 parallel be provided with two respectively with one cone end through hole 201, 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 fill hydraulic oil, outer ring one-way valve 10 is opened when pivoted loop 4 rotates clockwise, the hydraulic oil of right chamber 6 slowly flows into left chamber 5 along with pivoted loop 4 rotates clockwise, 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 block 2 and pivoted loop 4 are integrally connected, so valve block 2 moves with pivoted loop 4, thus the rotational speed of workpiece is cushioned.
One-way valve of the present invention is bored with band the through hole held and has been coordinated damping function, and one-way valve Compress Spring plays balancing gravity torsional interaction thus realizes revolution bidirectional damper and balance.
