An industrial robot with adjustable trajectory of welding machine

Abstract

An industrial robot having an adjustable welding machine track, comprising concave grooves (1) and a welded object (6), wherein reset holes (2) are provided inside both ends of the concave grooves (1), and a reset device is provided in each reset hole (2); each reset device comprises a reset steel wire rope (21), which extends to the outside of the reset hole (2); the interiors of the concave grooves (1) are respectively provided with a power driving device and an electronic control arrangement device, the power driving device comprising a motor (3) and gears (31); gear grooves (32) are provided in the inner bottom walls of the concave grooves (1), and the surfaces of the gears (31) are meshed with the inner walls of the gear grooves (32); the electrical control arrangement device comprises a positive copper strip (4) and a negative copper strip (41), both the positive copper strip (4) and the negative copper strip (41) being electrically connected to the motor (3) by means of energized bumps (42); and a bottom end part of each adjacent concave groove (1) is movably connected by means of a steering mechanism. In the industrial robot having the adjustable welding machine track, by means of the arrangement of reset devices, the reset springs between the adjacent concave grooves may be always tensioned, the elasticity of identical reset springs is the same, and a track formed by the plurality of concave grooves may form a regular radian. Due to the arrangement of the power driving device, the whole device may run in the concave grooves along the track which is formed by the connection of the plurality of concave grooves.

Description

technical field [0001] The invention relates to the technical field of welding robots, in particular to an industrial robot with adjustable trajectory of a welding machine. Background technique [0002] Welding robots are industrial robots engaged in welding (including cutting and spraying). According to the definition of the International Organization for Standardization (ISO) that an industrial robot belongs to a standard welding robot, an industrial robot is a multipurpose, reprogrammable, automatic control manipulator with three or more programmable axes, used in the field of industrial automation . [0003] At present, in the actual welding process of welding robots, especially when welding or painting relatively tall cylindrical shapes, manual operation is very troublesome. If aerial cranes are used to lift welding or painting equipment, the accuracy is difficult to guarantee, especially for large cylindrical inner walls. , when the cylindrical diameter is greater th...

Problems solved by technology

[0003] At present, in the actual welding process of welding robots, especially when welding or painting relatively tall cylindrical shapes, manual operation is very troublesome. If aerial cranes are used to lift welding or painting equipment, the accuracy is difficult to guarantee, especially for large cylindrical inner walls. , when the cylindrical diameter is greater than the height of a person, it is very inconvenient to weld or spray the inner wall. In addition, the trajectory of welding or spraying will also need to be changed with different requirements, which will increase the difficulty of welding or spraying, and the work of welding The environment is relatively harsh, and the smell it produces is very harmful to human health
