Problems solved by technology

However, this side-mounted robot is a cantilever structure, which reduces the rigidity of the robot and is generally suitable for robots with small loads.
Traditional articulated welding robots need to install motors at the joints, which makes the robot structure have shortcomings such as large moment of inertia and large error accumulation.

Abstract

The invention relates to a simple spot-welding robot mechanism which comprises a first welding torch rack position adjusting mechanism, a first welding torch rack attitude adjusting mechanism, a second welding torch rack position adjusting mechanism, a second welding torch rack attitude adjusting mechanism, a welding torch rack and a stand, wherein the welding torch rack is composed of a swinging rack and a rotating rack, the swinging rack is connected with the rotating rack by a fourteenth rotating pair, the swinging rack is connected with the first welding torch rack position adjusting mechanism by a fifteenth rotating pair, the swinging rack is connected with the first welding torch rack attitude adjusting mechanism by a tenth rotating pair, the rotating rack is connected with the second welding torch rack attitude adjusting mechanism by a second spherical pair, and a welding torch is arranged on the rotating rack. The simple spot-welding robot mechanism provided by the invention is driven by external rotating pairs, and all servo motors are installed on the stand, therefore, the weight of working bar parts can be reduced effectively, the accurate positioning of the working bar parts can be realized, and the working efficiency of the working bar parts can be improved.

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...
