Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of welding, and particularly relates to a small water tank automatic welding equipment. BACKGROUND

[0002] Welding refers to a process of forming permanent connection by using or not using filler material through heating, pressing or both. Welding can be used for metal and non-metal. In the manufacturing process of a circular water tank, top welding is a key step to ensure the sealing and structural strength of the water tank. However, in the actual production process, the welding operation of the circular water tank faces a series of challenges, especially in welding positioning and clamping, and welding heat and cooling management.

[0003] Specifically, the conventional welding equipment often lacks self-adaptive clamping capability for water tanks of different sizes when welding the circular water tank. Since the sizes of the water tanks are various, the conventional fixed clamping device cannot meet the diversified production needs, which not only limits the universality of the equipment, but also may cause the water tank to be unable to be stably fixed during clamping, thereby affecting the precision and safety of welding. Secondly, when welding the top of the water tank, the welding area generates extremely high temperature, and as the distance from the welding area gradually increases, the temperature gradually decreases. The cooling air flow of the water tank is often not accurately adjusted according to the temperature distribution of the welding area, which leads to insufficient cooling in the high-temperature area and excessive cooling in the low-temperature area, causing waste of resources and reduction of cooling efficiency, thereby affecting the production efficiency and cost control. Therefore, there is a deficiency, which cannot meet the welding use needs of manufacturers, and it is necessary to further improve.
