Abstract

The invention relates to a parallel driving mechanism with two-degree-of-freedom large-rotation-angle rotation. Belongs to the field of robot design and comprises a base, a frame arranged on the base, a movable platform and a transmission mechanism for driving the movable platform to move. The transmission mechanism comprises a first transmission shaft, a second transmission shaft, a horizontal rod and a first connecting rod connected with the horizontal rod; a first belt wheel is arranged on the first transmission shaft; a second belt wheel is arranged in the middle of the second transmission shaft, and the second belt wheel and the first belt wheel are located in the same plane. The first belt wheel and the second belt wheel are connected through a first rope. The second transmission shaft is connected with the horizontal rod through a second rope. One end of the first connecting rod is fixedly connected with the horizontal rod, and the other end is rotationally connected with the movable platform; the first transmission shaft is driven to sequentially drive the second transmission shaft, the horizontal rod and the first connecting rod to enable the movable platform to rotate. The mechanism solves the technical problems that an existing parallel driving mechanism with two-degree-of-freedom rotation is limited in rotation range and complex in structure.

Description

technical field [0001] The invention belongs to the field of robot design, in particular to a parallel drive mechanism with two degrees of freedom and large rotation angle. Background technique [0002] The parallel mechanism is a typical parallel drive arrangement. Since all drives are arranged on the base, or on the joints close to the base, the parallel drive mechanism has the characteristics of high stiffness, small cumulative error, and good dynamic characteristics. The two-degree-of-freedom rotating parallel mechanism is an important branch of the less-degree-of-freedom parallel mechanism. It has unique advantages in the attitude adjustment of the moving platform, so it is widely used in the attitude adjustment and self-stabilization of the platform of ships, vehicles or aircraft, antennas and solar panels. Orientation tracking, and areas such as bionic shoulder or hip joints. [0003] The existing two-degree-of-freedom parallel mechanism usually includes a constraini...
