Swing arm robotic arm

Abstract

This utility model provides a swing-arm manipulator, comprising: a base; a swing-arm mechanism including a first swing arm, a second swing arm, and a rotary cylinder, wherein the first swing arm is mounted on the base and has a wire-passing groove; the first and second swing arms are connected by the rotary cylinder, which can drive the second swing arm to rotate relative to the first swing arm; a first wire-passing hole is provided on the rotating shaft of the rotary cylinder, and the first wire-passing hole is connected to the wire-passing groove; and a working mechanism including a working cylinder and a first pipeline, wherein the working cylinder is disposed on the second swing arm, the first pipeline is connected to the working cylinder, and the wire passes along the first wire-passing hole and the wire-passing groove. On one hand, the first and second swing arms are connected by the rotary cylinder, and the rotary cylinder directly drives the second swing arm to rotate relative to the first swing arm, enabling the rotary cylinder to provide power; on the other hand, the first wire-passing hole on the rotating shaft of the rotary cylinder allows for internal wire routing within the swing-arm manipulator.
