Abstract： |
The invention is a two-freedom parallel robot mechanism, including stationary platform, dynamic platform and branch connecting the two platforms, the dynamic platform are set with two sliding rails and connected with the stationary platform through five branches; four ones of the five branches have the same structure and they include a sliding block and an extendable link rod as driving auxiliary, one end of each extendable link rod is fixed with the stationary platform and the other end is connected with the corresponding sliding block by rotary auxiliary; the fifth branch is a restriction branch, one end is fixed with the stationary platform and the other end is connected with dynamic platform by Hooke hinge; the four same branches are uniformly distributed with the restriction branch as center, two opposite branches are linked and move oppositely and the two sliding rails on the dynamic platform are parallel with the axis of the Hooke hinge on the restriction. It has high rigidity and precision, and other properties. |
