Abstract
The present invention relates to the field of robot technology, and specifically to a large-load robot joint structure, comprising a base, a screw hole, a swivel, a mounting frame, a large arm, a small arm and a first spring balancing cylinder, wherein the screw hole is arranged on the surface of the base, the swivel is movably mounted on the top of the base, the mounting frame is fixedly mounted on the upper surface of the swivel, the large arm is movably mounted on the inner side of the mounting frame, the small arm is movably mounted on the large arm, and a machine claw is mounted on the end extending outward, and the number of the first spring balancing cylinders is two. The large-load robot joint structure can enable the second spring balancing cylinder to follow the movement of the small arm through a following component, thereby reducing the stretching stroke of the small arm drive on the second spring balancing cylinder, avoiding excessive stretching of the spring in the second spring balancing cylinder, and reducing the driving torque at the same time, and adjusting the center of gravity of the robot when the small arm grabs and lifts the workpiece, thereby improving the stability of the robot.
