Description

Technical Field

[0001] The utility model relates to the technical field of welding robots, in particular to a height-adjustable electrical automation welding robot. Background Technique

[0002] Welding robots mainly consist of parts such as robotic arms, control systems, welding power sources, etc. The control system precisely controls the movement trajectory and welding parameters of the robotic arm according to the preset program and the information feedback by sensors, realizing the automatic welding of workpieces, and is widely used in industries such as automobile manufacturing, machining, aerospace, and electronics and electrical appliances; in automobile manufacturing, welding robots can be used for body welding, component welding, etc.; in machining, they can be used for the welding of large mechanical structures; in the aerospace field, they can be used for the welding of airplanes, spacecraft, etc.

[0003] In the patent document with the published announcement number CN214264445U, a height-adjustable electrical automation welding robot is disclosed, including a welding nozzle. A lead screw cylinder is provided below the welding nozzle. A lead screw nut is fixedly installed on the outer top wall of the lead screw cylinder. A mechanical joint is provided above the lead screw. One side of the mechanical joint away from the lead screw is rotatably connected to a first robotic arm. One end of the first robotic arm away from the mechanical joint is rotatably connected to a second robotic arm. On the one hand, through the setting of the lead screw, lead screw cylinder and lead screw nut, and on the other hand, through the rotational connection of the first bearing and the first connecting shaft, and the second bearing and the second connecting shaft, on the basis of adjusting the height of the welding nozzle, it solves the problem that the welding position of the existing height-adjustable electrical automation welding robot deviates due to the lack of a stable, reliable and highly accurate height adjustment device.

[0004] When the above device is in use, it can well adjust the height. However, during welding, the robot cannot adjust the welding position, resulting in the position of the robot being fixed and limited, so that it cannot move left and right and rotate in multiple directions, resulting in restrictions on the size of the object to be welded. The welding position that the welding robot can weld is limited. At the same time, the object to be welded cannot rotate when being clamped, resulting in an incomplete welding surface. Subsequently, it is necessary for workers to turn and move the object before clamping and fixing it again before welding can be carried out, thus reducing the welding efficiency.
