Abstract

The invention discloses automatic heat exchanger tube plate joint circular seam welding equipment which comprises a positioning mechanism, a rotary mechanism, a stepping motor, an extension plate, a welding gun holder and a welding gun, wherein the positioning mechanism comprises a positioning device as well as a tightening device and a hand wheel arranged on the positioning device; the welding gun holder is fixed on the rotary mechanism through the extension plate; and the welding gun is fixed on the welding gun holder. The automatic heat exchanger tube plate joint circular seam welding equipment is suitable for welding of joint circular seams of tube plates with different tube diameters, welds the circular seam through rotating the welding gun on the condition that the tube does not rotate, is fast in positioning, accurate in welding and high in degree of automation and has the advantages of being high in welding efficiency and stable circular seam welding quality.

Description

technical field [0001] The invention relates to the technical field of automatic control of the welding process, in particular to an automatic welding equipment for the circular seam of the tube plate joint of a heat exchanger. Background technique [0002] Pressure vessels are widely used in petroleum and chemical industries, and the quality of their tube-sheet joints determines the service life and performance of pressure vessels. At present, the manual welding of tube-sheet joints has high labor intensity, difficult quality assurance and poor appearance, while the practical application of automatic welding machines is seldom, and further research is needed. Contents of the invention [0003] The object of the present invention is to provide an automatic welding device for the circular seam of the tube-sheet joint of a heat exchanger, which is suitable for welding the tube-sheet joints with different pipe diameters and the pipes are not moved. [0004] In order to achie...
