High-speed two-degree-of-freedom planar transverse-movement robot mechanism

The invention provides a high-speed two-degree-of-freedom planar transverse-movement robot mechanism. The high-speed two-degree-of-freedom planar transverse-movement robot mechanism is composed of a first driving rod, a second driving rod, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, a fifth connecting rod, a sixth connecting rod, a seventh connecting rod, a movable platform and a base platform. A planar five-rod mechanism is composed of the first driving rod, the first connecting rod, the second connecting rod, the third connecting rod and the base platform. The fourth connecting rod, the fifth connecting rod, the sixth connecting rod and the seventh connecting rod are hinged to form a parallelogram mechanism. The third connecting rod, the seventh connecting rod, the second driving rod and the base platform are hinged to form another parallelogram mechanism. The two parallelogram mechanisms are directly connected in series to form a whole. The second connecting rod and the fourth connecting rod serve as two sides of a V-shaped combined part. The movable platform is connected with the fifth connecting rod. The high-speed two-degree-of-freedom planar transverse-movement robot mechanism is a series-connection and parallel-connection combined mechanism, and the number of movement parts far away from the base platform is small; in addition, driving pairs also serve as rotating pairs, the inertia load generated by the high speed is small, and high-speed movement is more easily achieved.
