Automatic two-gun welding for heating stove

Abstract

Disclosed is automatic two-gun welding for a heating stove. Automatic two-gun welding comprises a rack and a base. The base is connected with a bottom plate through a longitudinal moving mechanism. A welding platform is arranged on the bottom plate. A vertical plate is vertically installed on the rack. The vertical plate is connected with a transverse plate through a vertical moving mechanism. The transverse plate is connected with a sliding plate through a transverse moving mechanism. Two welding gun micro-adjusting mechanisms are arranged on the sliding plate. Circular fixed gears are vertically installed on the lower portions of the welding gun micro-adjusting mechanisms respectively. Welding guns are hinged to the middles of the fixed gears respectively. Automatic two-gun welding has the advantages that the welding guns are hinged to the circular fixed gears respectively, thereby being capable of rotating along the fixed gears through first motors and first gears respectively; the angles of the welding guns can be accurately controlled and welding angles can also be accurately adjusted by controlling the rotation speed and the starting time of the first motors, so that welding spots are prevented from shifting, and accordingly a gap, between a welded pipe mouth and a welded pipe shell, caused by a weld joint is avoided; the firmness and the welding effect are improved. In addition, according to automatic two-gun welding, simultaneous welding of two components can be achieved by arranging the two welding guns, so that the welding efficiency is improved.

Description

technical field [0001] The invention relates to a welding device, in particular to a heating furnace double gun automatic welding. Background technique [0002] After the nozzle and the shell of the heating furnace smoke pipe are matched, the nozzle and the shell need to be welded together. At present, it is impossible to accurately adjust the welding angle. The operator can only generally adjust the welding angle by relying on experience. Not only the welding quality cannot be maintained It is stable, and it is easy to cause the solder spot to deviate from the weld seam. There is a gap between the welded nozzle and the shell, and the firmness is obviously low. It is easy to fall off during use, and the welding effect is not good. And the welding of heating furnace can only realize welding one part at a time at present, can't weld a plurality of parts simultaneously, and welding efficiency is lower. Contents of the invention [0003] In order to solve the above problems, ...

Problems solved by technology

[0002] After the nozzle and the shell of the heating furnace smoke pipe are matched, the nozzle and the shell need to be welded together. At present, it is impossible to accurately adjust the welding angle. The operator can only generally adjust the welding angle by relying on experience. Not only the welding quality cannot be maintained It is stable, and it is easy to cause the solder joints to deviate from the weld seam. There is a gap between the welded nozzle and the shell, and the firmness is obviously low. It is easy to fall off during use, and the welding effect is not good.

Moreover, the current welding of the heating furnace can only realize welding one part at a time, and it is impossible to weld multiple parts at the same time, and the welding efficiency is low
