Novel four-degree-of-freedom articulated robot structure

Abstract

The invention discloses a novel four-degree-of-freedom articulated robot structure. The novel four-degree-of-freedom articulated robot structure comprises a base, a lifting seat, a first mechanical arm, a Y-axis cover, a second mechanical arm, and an operation main shaft, wherein the lifting seat vertically moves in the direction of a Z-axis under the limiting actions of a lead screw, a lead screw, and a guide rail pair, the first mechanical arm can rotate around an X-axis parallel to the Z-axis to be installed on the lifting seat, the Y-axis cover is installed on the first mechanical arm, bears a first Y-axis speed reduction device shaft and a second Y-axis speed reduction device shaft, and is provided with through holes for a Y-axis servo motor shaft, the first Y-axis speed reduction device shaft and the second Y-axis speed reduction device shaft to penetrate, the second mechanical arm can rotate around the Y-axis parallel to the X-axis to be installed on the first mechanical arm, and the operation main shaft can rotate around an R-axis parallel to the Y-axis to be installed on the second mechanical arm. The novel four-degree-of-freedom articulated robot structure is simple in structure, low in cost, large in operation space, and high in operation accuracy.

Description

technical field [0001] The invention belongs to the technical field of industrial robots, and in particular relates to a novel four-degree-of-freedom planar joint robot structure. Background technique [0002] Robot technology is a comprehensive application of multiple disciplines. Industrial robots realize autonomous movement through robot joints. Among many types of robots, planar joint robots are small in size, simple in transmission principle, and have greater flexibility in movement in the plane. The movement of the axes is very rigid, making them ideal for repetitive tasks such as handling, welding and assembly, so they are widely used in industrial production. Industrial robotics also integrates many cutting-edge disciplines such as mechanical engineering, electrical engineering, microelectronics engineering, computer engineering, control engineering, bionics and artificial intelligence engineering. Combining it with computer-aided design system and computer-aided ma...
