Structure parameter-adjustable parallel motion table with combined spring bearing branches

The invention relates to a structure parameter-adjustable parallel motion table with combined spring bearing branches. The table comprises a base platform, a movement platform, six active branches of the same structure, three spherical hinge connection combination blocks of the same structure, three universal hinge connection combination blocks of the same structure and three passive bearing branches of the same structure; each active branch is compose of an electric cylinder and a motor; two ends of each active branch are respectively connected with the movement platform and the base platform through a corresponding spherical hinge connection combination block and a corresponding universal hinge connection combination block; each passive bearing branch is composed of a guide rod, a guide sleeve, a first bearing spring, a second bearing spring and a bearing spring guide sleeve; and two ends of each passive bearing branch is respectively connected with the movement platform and the base platform through spherical hinges with bases. According to the structure parameter-adjustable parallel motion table, the platforms have strong bearing capacity, and control on the active branches and the passive branches is simple. The structure parameter-adjustable parallel motion table is suitable for multi-purpose simulators and multi-purpose stabilization platform.
