The present invention discloses a four-axis horizontal joint
robot, including a
machine base and a
control system, wherein the top of the
machine base is rotatably connected to a rotating sleeve, the left side of the rotating sleeve is fixedly connected to a rotating plate, the left side of the top of the rotating plate is rotatably connected to a working
chassis, and the internal thread of the working
chassis is connected to a lifting screw, and the present invention relates to the technical field. The four-axis horizontal joint
robot, by providing a smoothly rotatable rotating ring on the
machine base, and using a main support frame and a side support frame to support the rotating plate, can apply part of the weight of the left structure to the rotating ring, so that the rotating plate is more stable when rotating, and the slide rail is provided to cooperate with the slider and the connecting rod, which can pull the working
chassis within a certain range of rotation of the working chassis, that is, improve the connection stability between the working chassis and the rotating plate, and avoid deviation of the
processing position due to center offset after long-term use, thereby affecting the
processing quality.
