Abstract
A parallel mechanism with three-dimensional translation and one-dimensional rotation include a fixing rack, a mobile platform and four chains of the same structure which are symmetrically set between the fixing rack and the mobile platform. Each chain has a near rack rod and two parallel far rack rods. The mobile platform includes a main platform and an assistant platform connected by a revolute joint and perpendicular to each other. Each end of the main platform and the assistant platform is connected with a corresponding lower connecting shaft separately.
