Description

Technical Field

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

[0002] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Welding achieves the purpose of joining through the following three ways: 1. Fusion welding - heating the workpieces to be joined to partially melt them to form a molten pool. The molten pool is joined after cooling and solidification. If necessary, molten fillers can be added to assist. It is suitable for welding of various metals and alloys without pressure. 2. Pressure welding - pressure must be applied to the weld during the welding process. It belongs to the processing of various metal materials and partial metal materials. 3. Brazing - using metal materials with lower melting points than the parent material as brazing filler, using liquid brazing filler to wet the parent material, fill the joint gap, and diffuse with the parent material to achieve linking of the weldment. It is suitable for welding of various materials, and also for welding of different metals or heterogeneous materials.

The angle adjustment mechanism 2 also includes two driven bevel gears 209 arranged on the outer surface of the fixing mechanism 3, and the driving bevel gear 208 is meshed with the driven bevel gear 209.

[0024] The angle adjustment mechanism 2 in this embodiment drives the first rotating shaft 202 and the driving gear 203 to rotate by rotating the output shaft of the first motor 201. The driving gear 203 cooperates with the driven gear 205 to drive the second rotating shaft 204 to rotate. The second rotating shaft 204 can drive the driving wheel and the driving bevel gear 208 to rotate. The transmission mechanism 206 is used to drive the third rotating shaft 207 to rotate. The driving bevel gear 208 and the driven bevel gear 209 cooperate to drive the sleeve 303 to rotate, so that the sleeve 303 drives the metal tube 4 to rotate.
