Abstract
Disclosed is a three-branched six-degree-of-freedom parallel mechanism with curved sliding pairs, which includes a base, a moving platform, and three identical kinetic branches. The kinetic branches are radially and evenly distributed and arranged between the base and the moving platform. Each kinetic branch includes a first curved link assembly, a first motor, and a support link. One end of the support link is hinged to the moving platform. One end of the first curved link assembly is hinged to the support link. The first motor is disposed on the base and is configured for driving the first curved link assembly to rotate, where an arc length of the first curved link assembly is changed as the first curved link assembly is driven to rotate.
