Description

Technical Field

[0001] The present application belongs to the field of welding robots, and specifically relates to a six-axis lightweight welding robot. Background Art

[0002] The welding robot is an industrial robot engaged in welding. For example, the existing utility model patent with application number: CN201720801326.3 discloses a lightweight six-degree-of-freedom space controllable mechanism type high-speed welding robot, wherein the first servo motor drives the fourth final sleeve to move forward and backward on the forearm through a transmission chain including the first active rod, the second servo motor drives the forearm to rotate through a transmission chain including the second active rod, and the forearm drives the actuator to swing left and right on the working plane through the transmission chain, the third servo motor drives the second final sleeve to move forward and backward on the forearm through a transmission chain including the third active rod, the second final sleeve and the fourth final sleeve drive the actuator to adjust the elevation angle after being transmitted through a transmission chain consisting of the first connecting rod to the fifteenth connecting rod, and the fourth servo motor controls the lifting height of the rotating shaft relative to the center of the rotating pair four through a transmission chain including the fourth active rod, that is, controls the lifting height of the actuator. This utility model overcomes the shortcomings of most existing linkage mechanisms that can only drive the transmission in a plane and have poor spatial stiffness, and has the characteristics of realizing spatial transmission without installing motors and reducers on the joints. However, since the base of the six-axis welding robot is fixed, the working range of the six-axis welding robot is limited. In view of this, we provide a six-axis lightweight welding robot.
