Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a welding device for an aluminum alloy oxygen making machine frame. Background Art

[0002] With the rapid development of medical technology, medical oxygen concentrator equipment has become an indispensable medical equipment for major medical institutions. It can provide patients with a stable and efficient oxygen supply, which is of great significance for ensuring the life safety of patients and improving the quality of medical care. Oxygen concentrator equipment is a device for producing oxygen, which includes oxygen liquefaction oxygen concentrators and molecular sieve oxygen concentrators. For example, the working principle of oxygen liquefaction oxygen concentrators is to use air separation technology, first using a compressor as a power to compress the input air to produce high-pressure gas, and then perform gas-liquid separation and distillation to obtain oxygen; the working principle of molecular sieve oxygen concentrators is to use air separation technology, first using a compressor as a power to compress the input air to produce high-pressure gas, and then use gas molecular sieves to make oxygen molecules pass through and obtain high-concentration oxygen. The bottom of large medical oxygen concentrator equipment is usually provided with an aluminum alloy base frame. The base frame is the bottom support structure of large medical oxygen concentrator equipment. Aluminum alloy has the characteristics of high strength, light weight, and corrosion resistance. It can not only meet the strength requirements, but also effectively reduce the overall weight of the equipment, which is convenient for transportation and installation.

[0003] The aluminum alloy base frame at the bottom of the medical oxygen concentrator equipment is usually a flat frame structure, which is composed of an outer frame and multiple inner frame rods that are cross-distributed horizontally and vertically inside the outer frame. The multiple inner frame rods are welded inside the outer frame. During the welding process of the base frame, the prior art usually uses manual spot welding of multiple inner frame rods to the outer frame one by one, which is cumbersome and time-consuming. During welding, the outer frame is reserved with inner frame rod installation position marks to facilitate the welding and installation of the inner frame rods. However, due to the large error and uncontrollability of manual operation, it is difficult to accurately position the inner frame rods in the outer frame, resulting in a large deviation in the structure of the base frame after welding, affecting the stable installation of the equipment. It is easy to cause a lot of rework and material waste due to inaccurate welding position. Therefore, it is of great significance to design a welding device with a relatively simple structure, easy to use, and auxiliary positioning welding of the inner frame rods.

At this time, the top plate 301 drives the protrusion 302 to escape from the drop-out notch 13, so that the drop-out notch 13 is in an open state, and the base frame workpiece after the welding process automatically falls out through the drop-out notch 13. The top of the top connecting plate 301 sucks air from the external environment through the air pump 312 and compresses and delivers it to the air supply pipe 307.
