The invention provides a novel four-axis parallel robot movable disk (movable base), and relates to the field of robots. The four-axis parallel movable disk comprises four ball-head brackets, wherein each ball-head bracket is hinged with two adjacent ball-head brackets through connection rods; one pair of two adjacent ball-head brackets are rotatably connected with two ends of a first gear ring connection rod, respectively; the other pair of two adjacent ball-head brackets are rotatably connected with two ends of a second gear ring connection rod, respectively; middle parts of the first gear ring connection rod and the second gear ring connection rod are rotatably connected with two ends of a driving wheel fixing rod, respectively; a driving wheel is arranged at the middle part of the driving wheel fixing rod; an arc-shaped rack is mounted on the second gear ring connection rod; the driving wheel is meshed with the rack; a driving shaft is fixed at the center of the driving wheel; and the driving shaft is rotatably connected with the driving wheel fixing rod. A four-axis parallel robot applies the above four-axis parallel movable disk. According to the four-axis parallel movable disk, the technical problem that the existing four-axis parallel robots are relatively high in load and small in workpiece movement space is solved.
Description
technical field [0001] The invention relates to the technical field of robots, in particular to a four-axis parallel movable disk and a four-axis parallel robot. Background technique [0002] The parallel mechanism can be defined as a closed-loop mechanism in which the moving platform and the fixed platform are connected by at least two independent kinematic chains, the mechanism has two or more degrees of freedom, and is driven in parallel. Parallel robots and traditional industrial serial robots have a philosophical relationship of opposites and unity. Compared with serial robots, parallel robots have the following characteristics: (1) No cumulative error and high precision; (2) The driving device can be placed on a fixed platform The position on or close to the fixed platform, so that the moving part is light in weight, high in speed and good in dynamic response; (3) compact in structure, high in rigidity, and large in carrying capacity; (4) completely symmetrical paralle...
