Abstract

The invention relates to a wheel train type movable platform for a four-axis parallel robot. The wheel train type movable platform comprises a main shaft, a subplatform I, a subplatform II and a four-axis parallel mechanism, wherein the subplatform I and the subplatform II are crossed with each other; two groups of relative branched chains are mounted on the four-axis parallel mechanism; each of the relative branched chains is provided with a lower connecting shaft; and the subplatform I and the subplatform II are fixedly connected with corresponding lower connecting shafts. The wheel train type movable platform is compact in structure, light and handy in design, large in transmission range and excellent in carrying capacity, meets the requirements of high-speed grab-put operation, adopts wheel train transmission, is reliable in transmission, can realize transmission of the main shaft, improves the transmission accuracy, is low in operating noise and high in efficiency, and meets the requirements of complicated grab-put operation.

Description

technical field [0001] The invention relates to the technical field of parallel robots, in particular to a wheel train type moving platform for a four-axis parallel robot. Background technique [0002] Due to the advantages of high rigidity, high precision, and high speed, parallel mechanisms are gradually used in parts processing, medicine, electronics and other industries. At present, the movement of the end effector of the parallel mechanism is mostly determined by the body of the parallel mechanism, and it is rare to realize the rotation according to the structure of the moving platform, and achieve a certain speed-up ratio. [0003] The invention patent with the publication number CN102642205A discloses a moving platform structure of a four-degree-of-freedom parallel mechanism. The connecting mechanism and the rotating mechanism composed of the mechanism are composed. The advantage of this moving platform is that the relative movement of the upper and lower moving pla...
