Abstract

The invention belongs to the technical field of welding tools, and particularly relates to a seal head welding machining tool of a liquid ammonia tank. A pipe barrel-semiring rail-semiring gear ring assembly is manually assembled and placed on a driven rotating wheel; and a flange seal head and a flange-free seal head are carried by being assisted by manpower, a right locating assembly and a leftlocating assembly achieve automatic clamping, automatic turnover and forward pushing to be in butt joint with the two ends of a pipe barrel, spot welding of a robot is achieved, the right locating assembly and the left locating assembly loosen the seal heads and automatically return to the initial positions, and full welding of the robot is achieved. The seal head welding machining tool and the intelligent robot are used in cooperation and linkage, semi-automation can be achieved, weld joint specifications are uniform and unified, the welding quality can be greatly improved, repair welding work can be reduced, the work efficiency can be improved, and the problem of labor shortage of electric welders can be solved.

Description

technical field [0001] The invention belongs to the technical field of welding tooling, and in particular relates to a head welding processing tooling for a liquid ammonia tank. Background technique [0002] The liquid ammonia tank is a sealed container for canning liquid ammonia. It is a pressure vessel, and the inside bears a large pressure of liquid ammonia, which has high requirements for safety. [0003] Liquid ammonia tank, including oval head with flange, tube and oval head without flange. , Welds are generally subject to non-destructive testing to ensure that there are no welding defects in the welded parts. For liquid ammonia tanks with a diameter of 600 mm, the thickness of the steel plate used is often more than 10 mm, and a V-shaped groove is used to ensure that the materials are fully connected. [0004] The traditional liquid ammonia tank is manually welded by manual group spot welding and manual hand-held welding torch welding. Manual welding is difficult t...
