Abstract

The invention relates to the technical field of metal welding, and provides a storage tank body welding device which comprises a fixed platform which is provided with a rotating disc and two stand columns. Two annular rails are further fixed between the two stand columns. A welding trolley is arranged on the annular rails. An outer welding gun is arranged on the welding trolley, and outer welding seams are formed at the joint of a tank body and a tank bottom and the joint of the tank body and a tank opening respectively. A centering shaft extends into the storage tank. A centering adjusting mechanism is arranged on the centering shaft. An inner welding mechanism is further arranged on the centering shaft, and an inner welding seam is formed on the inner wall of the storage tank along with rotation of the storage tank. Therefore, a rotary table, clamping jaws and a pressure plate are arranged on the fixed platform, so that the tank opening, the tank body and the tank bottom of the storage tank are vertically fixed. The outer welding gun moves on a circular rail, so that the formation of the outer welding seams is realized. And meanwhile, the inner welding mechanism is arranged, and after the outer welding seams are formed, the inner welding seam can be conveniently formed in the storage tank. The welding automation degree is high, manual work is replaced to enter the tank for operation, the labor intensity is relieved, and the welding efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of metal welding, in particular to a tank body welding device. Background technique [0002] Pressure vessel storage tanks, such as those used to store refrigerants. Because the refrigerant is easy to vaporize, its storage tank is usually required to be able to withstand a certain pressure. Refrigerator storage tanks are usually formed by welding, but as a pressure vessel, there are certain requirements for the pressure bearing capacity of the weld. [0003] see figure 1 , the structure of the existing refrigerant storage tank is usually that the tank bottom 101, the tank body 102, and the tank mouth 103 are arranged in sequence, and the positions where the two are combined are connected as a whole by welding. [0004] For storage tanks with large capacity, in order to meet the pressure-bearing standard, the welding process is usually carried out on the outside and inside of the tank at the welding positi...
