Patent attributes
The present invention provides a four-chain six-degree-of-freedom hybrid mechanism. The four-chain six-degree-of-freedom hybrid mechanism comprises a fixed platform, a sliding rail mounted on the fixed platform, two sliding blocks, a mobile platform and four linear actuator chains connecting the mobile platform with a first sliding block and a second sliding block. The mobile platform is square-shaped. In the four linear actuator chains, the first linear actuator chain and the third linear actuator chain have the same structure while the second linear actuator chain and the fourth linear actuator chain have the same structure. The mobile platform can achieve six degrees of freedom. The four linear actuator chains coordinate to drive so as to achieve two translational degrees of freedom and two rotational degrees of freedom; the first sliding block and the second sliding block coordinate to drive so as to achieve the other translational and rotational degrees of freedom.
