Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy fuel tank welding technology, and in particular to an aluminum alloy fuel tank welding device. Background Technology

[0002] With the rapid development of modern industry, aluminum alloys, due to their excellent comprehensive properties such as low density, high strength, and good corrosion resistance, have been widely used in the field of fuel tank manufacturing. Compared with fuel tanks made of traditional materials, aluminum alloy fuel tanks can effectively reduce the overall weight of equipment, improve fuel efficiency, and extend service life, thus occupying an important position in many industries such as automobiles, aerospace, and shipbuilding. In the manufacturing process of aluminum alloy fuel tanks, welding is a key step in ensuring the quality and performance of the tank. However, the welding of aluminum alloy fuel tanks currently faces many severe challenges.

[0003] Traditional clamping methods are ill-suited for the complex shapes and structures of irregularly shaped fuel tanks, and cannot achieve uniform and stable clamping of various parts of the tank. During the welding process, the fuel tank is prone to displacement, shaking, or deformation. This not only leads to deviations in the welding position, causing the weld to deviate from the predetermined trajectory and resulting in quality problems such as discontinuous welds and inconsistent widths, but also affects the stability of welding parameters, further reducing welding quality and increasing the scrap rate. Therefore, a welding device for aluminum alloy fuel tanks is proposed. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides a welding device for aluminum alloy fuel tanks, which has the following advantages:

[0016] 1. This aluminum alloy oil tank welding device, through the setting of the clamping mechanism, when in use, places the irregular aluminum alloy oil tank in the middle of two clamping plates, and then activates the hydraulic rods on both sides.
