Smokeless welding devices for machine manufacturing

Abstract

The invention discloses a smokeless welding device for machine manufacturing, and relates to the technical field of machine manufacturing. The smokeless welding device comprises a workbench, and further comprises an adjusting mechanism, a clamping mechanism, a flue gas purifying mechanism and a welding table located in the middle of the upper end of the workbench, and four placing plates are arranged on the upper surface of the welding table in a rectangular shape. According to the welding device, three welding guns are used in cooperation with a rotary welding table, multiple welding positions on a machined object can be conveniently welded at a time, continuous welding of the machined object can be achieved, meanwhile, the clamping mechanism is designed in cooperation with the placing plates, the machined object can be conveniently clamped and fixed, and influence on welding effect due to movement or shaking of the machined object in welding process is avoided; and in addition, a protective shell is used in cooperation with the flue gas purifying mechanism, flue gas generated in the welding process is conveniently sucked into a purification cavity to be purified and then discharged, and the device is low in cost, high in welding effect and suitable for welding machining of large-batch objects.
