Description

Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to automatic welding equipment for metal welding parts. Background Art

[0002] As one of the key processes for connecting metal materials, welding technology has experienced a leap forward from manual welding to mechanized, automated and even intelligent welding since the Industrial Revolution. Early manual welding relied on the welder's skills and experience, was inefficient and had large quality fluctuations. With the advancement of science and technology, especially the rapid development of electricity, electronic control technology and materials science, welding technology has gradually achieved automation and intelligence, greatly improving production efficiency, welding quality and operational safety.

[0003] Existing automatic welding equipment for metal welded parts usually uses a manual handheld welding gun or a fixed welding gun for welding. Two sets of metal welded parts are fixed on the welding platform by bolts for welding. Some automatic welding equipment for metal welded parts also uses a manual handheld welding gun to weld metal pipes in circles. The welding angle of the pipe is changed by installing and disassembling the clamping components to achieve welding without dead angles of the pipe.

[0004] On the one hand, the existing method of fixing metal welded parts with bolts is relatively cumbersome to operate, and a single set of bolts cannot ensure that the metal welded parts remain centered in the center of the clamping assembly, so that the welding height of the welding gun cannot be kept consistent, resulting in poor welding quality. On the other hand, the existing metal pipe circle welding requires repeated adjustment of the clamping assembly to change the welding angle, which cannot allow the metal pipe to rotate in a circle, and the welding efficiency is low. Therefore, an automatic welding equipment for metal welded parts is proposed to solve the above problems. Utility Model Content
