Abstract

The invention provides a novel plane articulated robot structure which comprises a base, a lifting seat, a first mechanical arm, a second mechanical arm and an operation spindle. The base functions in supporting and reducing vibration; the lifting seat vertically moves along a Z-axis direction under the limiting action of a lead screw and a polished shaft; the first mechanical arm is rotatably mounted on the lifting seat by taking an X axis parallel to a Z axis as a rotating center; the second mechanical arm is rotatably mounted on the first mechanical arm by taking a Y axis parallel to the X axis as a rotating center; the operation spindle is rotatably mounted on the second mechanical arm by taking an R axis parallel to the Y axis as a rotating center. The vertically moving Z axis of a plane articulated robot with four degrees of freedom moves to the base of the robot, so that the inertia of the mechanical arms of the industrial robot can be decreased by the design, stress of the mechanical arms serving as cantilever beams is improved, the running speed and control stability of the robot are effectively improved, and the working space of the industrial robot is enlarged.
