Multi-degree-of-freedom vibration isolation bearing platform

Abstract

The invention discloses a multi-degree-of-freedom vibration isolation bearing platform which comprises a computer, a control card and a rotary vibration isolation bearing platform, wherein the bottom of a support leg of an azimuth platform in the rotary vibration isolation bearing platform is fixedly connected with a laminated vibration isolation rubber support. A Z-axis drive motor in the support leg is connected with the azimuth platform. An X-axis guide rail, an X-direction platform, an X-axis screw and an X-axis drive motor arranged on the azimuth platform are sequentially connected; and a Y-axis guide rail, a Y-direction platform, a Y-axis screw and a Y-axis drive motor arranged on the X-direction platform are sequentially connected. The Y-direction platform is provided with a Z-axis rotation drive motor and a stage. The Z-axis drive motor, the X-axis drive motor, the Y-axis drive motor and the Z-axis rotation drive motor are electrically connected with the control card respectively; and the control card is electrically connected with a computer. According to the invention, 4-degree-of-freedom adjustment can be performed on the platform in a vibration isolation condition, the pitching and rolling degree of freedom can be subjected to micro adjustment, and horizontal adjustment of the platform can be realized. The multi-degree-of-freedom vibration isolation bearing platform disclosed by the invention has the advantages of simple structure, heavy load, high position accuracy, automatic control and wide application.
