Embodiment Construction
[0018] First introduce the body structure of the horizontal joint robot, refer to figure 1 , the horizontally articulated robot 100a includes a base 2, on which a first rotating shaft C1 is provided; a boom 4, one end of which is rotatably connected to the base 2 through the first rotating shaft C1, and the other end is provided with a second rotating shaft C2 The small arm 11, one end of which is rotatably connected to the other end of the big arm 4 through the second rotating shaft C2; the second rotating shaft C2 is parallel to the first rotating shaft C1. The servo motor and the corresponding deceleration device for driving the boom 4 to rotate relative to the base 2 are installed inside the base 2 . The other three motors are installed inside the forearm 11 , wherein the servo motor and the corresponding deceleration device for driving the forearm 11 to rotate relative to the boom are located at the rear end of the forearm 11 , that is, near the end of the boom 4 . The f...

The invention relates to a horizontal joint robot. The horizontal joint robot comprises a base, a large arm, a small arm and a cover. The base is provided with a first rotating shaft C1, a servo motor used for driving the first rotating shaft C1 to rotate, and a corresponding reduction gear. One end of the large arm is rotatably connected with the base through the first rotating shaft C1, and the other end of the large arm is provided with a second rotating shaft C2. One end of the small arm is rotatably connected with the other end of the large arm through a second rotating shaft C2, and the other end of the small arm is provided with a ball screw and a ball spline. The small arm is further provided with a servo motor used for driving the second rotating shaft C2 to rotate and a corresponding reduction gear, a servo motor M1 used for driving the ball spline and a corresponding synchronous belt drive system I, and a servo motor M2 used for driving the ball screw and a corresponding synchronous belt drive system II. The cover is used for covering the small arm. The base, the large arm and the small arm together constitute a set of air forced convection system. The horizontal joint robot has the advantages of being simple in structure, good in heat dissipation performance, high in precision, good in rigidity and high in reliability.
Description
technical field [0001] The invention relates to a horizontal joint robot, in particular to a horizontal joint robot with a forced air convection system. Background technique [0002] Horizontal joint robot is a widely used industrial robot for high-speed, flexible sorting and assembly. It has three degrees of freedom of rotation and one degree of freedom of movement. In the current traditional horizontal joint robot, the servo motor and reducer driving the first joint are sealed in the base, and the servo motor and transmission device driving the second to fourth joints are sealed in the forearm. Poor, especially the forearm has three motors at the same time, and the servo motor is often overloaded and heats up seriously. Under unfavorable conditions, the air temperature in the forearm can rise to 50° or even higher. The rise in temperature inside the forearm seriously affects the performance and life of the servo motor, synchronous belt, ball screw and ball spline, and eve...
