The invention discloses a five-axis parallel robot with a quadrangular mechanism. The quadrangular mechanism comprises a bottom rod, a top rod, a first linear driving mechanism and a second linear driving mechanism. The bottom rod is connected with a base. The top rod is connected with a movable platform. The bottom rod, the first linear driving mechanism and the second linear driving mechanism and the top rod are sequentially and rotationally connected end to end to form a plane four-connecting-rod mechanism. Both the first linear driving mechanism and the second linear driving mechanism drive the top rod. The two sides of the quadrangular mechanism are provided with a fourth linear driving mechanism and a fifth linear driving mechanism respectively. The two ends of the fourth linear driving mechanism and the fifth linear driving mechanism are hinged to the base and the movable platform respectively. Both the fourth linear driving mechanism and the fifth linear driving mechanism drive the movable platform. The five-axis parallel robot has the parallel structure advantages of being good in dynamics performance, large in rigidity and high in speed, and solves the problems that an existing parallel machine tool or robot is small in rigidity and poor in dynamics performance.
