Description

technical field

[0001] The invention relates to the field of industrial welding robots, in particular to a simple spot welding robot mechanism. Background technique

[0002] Welding robots are industrial robots that are engaged in welding, including cutting and spraying. According to the definition of the International Organization for Standardization (ISO) Industrial Robot Terminology Standard, an industrial robot is a multi-purpose, reprogrammable automatic control manipulator (Manipulator), with three or more programmable axes, used in industrial automation field. Spot welding is not very demanding on the robot used. Because spot welding only needs point control, there is no strict requirement for the movement trajectory of the welding tongs between points. The welding robots produced in various countries in the world are basically articulated robots, and most of them have 6 axes. Among them, the 1, 2, and 3 axes can send the end tool to different spatial positions, wh...
