Abstract
A 2 DOFs decoupling parallel mechanism provided by the present disclosure comprises a fixed platform, a rotation assembly, a moving platform, an arc kinematic chain, and an arc rod. In the 2 DOFs decoupling parallel mechanism, the rotation assembly can drive the moving platform to rotate by 360 degrees around a direction being perpendicular to the fixed platform, the arc rod reciprocates along the tangential direction of the arc kinematic chain to enable the moving platform to rotate around an axis of a plane where the arc kinematic chain is located. In this way, the rotations of the moving platform in two directions are respectively driven by driving units in two directions and being independent from each other, such that the two rotation actions of the mechanism have decoupling capability.
