Description

Technical Field

[0001] The utility model relates to the technical field of welding tooling, in particular to a fuel atomizing nozzle welding tooling. Background Art

[0002] In the working process of existing aircraft engines, the combustion heater used is generally a fuel heater. There are three types of nozzles for general combustion heaters: pressure atomization nozzle, air atomization nozzle, and evaporation tube nozzle. Pressure atomization nozzles (commonly known as centrifugal nozzles) are in a high temperature environment for a long time, and the nozzle parts are prone to deformation, which affects the spray effect and thus the combustion efficiency. At present, most boilers and kilns that burn heavy oil or crude oil use centrifugal nozzles. Since the viscosity of the fuel is still very large after heating, it affects the atomization quality and spray cone angle, the atomization effect is not good, and the uniformity of the oil and gas distribution in the combustion chamber is seriously affected, and the combustion efficiency is very low. Although the air atomization nozzle can improve the atomization quality, it requires more high-pressure steam (or cold air), which increases the additional energy consumption, and the comprehensive effect is still not ideal. The evaporation tube nozzle works in the flame for a long time. In order to prevent its ablation and deformation, the structural design requirements of the evaporation tube are high. In order to meet the ignition needs, it is also necessary to design a matching auxiliary combustion chamber to provide an ignition torch.

[0003] Among them, the general centrifugal nozzle and pneumatic atomizing nozzle have poor atomization effect on heavy oil and crude oil, and have defects such as high fuel consumption rate during the combustion process. However, the atomization performance of ultrasonic burners is generally better than other types of burners, and it is easy to achieve low-oxygen combustion, thereby reducing the emission of smoke and nitrogen oxide pollutants in the flue gas.

[0004] The atomizing nozzle plays a very important role in atomization. When producing the atomizing nozzle, the air intake pipe needs to be welded on the atomizing nozzle body. However, in the actual production process, the atomizing nozzle and the center hole of the air intake pipe body are not accurately positioned during installation, which affects the work of the atomizing nozzle. At the same time, the welding process is controlled manually, which leads to inconvenience in welding the atomizing nozzle, low welding efficiency and low yield rate.

[0005] Therefore, the utility model proposes a fuel atomizing nozzle welding tool to solve the above problems. Utility Model Content

[0006] The utility model aims to provide a fuel atomizing nozzle welding tool, which is used to solve the problems in the prior art that the atomizing nozzle and the center hole of the air intake pipe body are not accurately positioned, which affects the work of the atomizing nozzle, has low welding efficiency and low yield.

[0014] Furthermore, a notch is provided on the base between the first limiting block and the third limiting block.

[0015] By adopting the above technical solution, the atomizing nozzle and the air intake pipe can be welded in multiple directions through the notch, thereby increasing the convenience of the welding process and ensuring stable welding.

[0016] Furthermore, a fourth limiting block is arranged between the first limiting block and the third limiting block, and the fourth limiting block is arranged perpendicular to the third limiting block and is arranged on one side of the third limiting block.

[0017] By adopting the above technical solution, the second spring causes the second gasket to contact the atomizing nozzle through elastic force, thereby avoiding wear and damage to the air intake pipe and ensuring the integrity of the finished product.

[0018] Furthermore, a second gasket is provided between the fourth limiting block and the air intake pipe, and a second spring is provided between the second gasket and the fourth limiting block.

[0019] By adopting the above technical solution, the second spring causes the second gasket to contact the atomizing nozzle through elastic force, thereby avoiding wear and damage to the air intake pipe and ensuring the integrity of the finished product.

[0020] Furthermore, a clamping device is arranged in parallel on one side of the fourth limiting block, and the clamping device comprises a fixed block and a fourth gasket. The fixed block is fixed on the base, and the fourth gasket moves relative to the fixed block via a screw.

[0021] By adopting the above technical solution, the air intake pipe can be tightened together with the clamping frame to avoid loose gaps, thereby ensuring the tightness of the connection between the atomizing nozzle and the air intake pipe, and further ensuring the progress of the welding work.

[0022] In summary, compared with the prior art, the utility model has the following beneficial effects:

[0023] The utility model can fix the atomizing nozzle and the air intake pipe, thereby ensuring the tightness of the connection between the atomizing nozzle and the air intake pipe and avoiding loose gaps.

A first gasket 3 is arranged between one end of the first limit block 2 and the atomizing nozzle, and a first spring 4 is arranged between the first gasket 3 and the first limit block 2, and then when the atomizing nozzle is pressed against the first limit block 2 and the second limit block 5, the first spring 4 causes the first gasket 3 to contact the atomizing nozzle through elastic force, thereby avoiding wear and damage to the atomizing nozzle and ensuring the integrity of the finished product. A third limit block 6 is provided at the lower end of the limit block, and the third limit block 6 is provided in parallel with the first limit block 2, and the third limit block 6 is flush with the first limit block 2, so that the air intake pipe is placed in close contact with the third limit block 6, so that the atomizing nozzle and the center hole of the air intake pipe body can be accurately positioned, which is convenient for the accuracy after welding and ensures the yield rate. A clamping frame 7 is rotatably provided on the base 1, and after the air intake pipe is placed on the base 1, the air intake pipe can be horizontally clamped by rotating the clamping frame 7, so as to further ensure the stability of the air intake pipe during welding.

So that the air intake pipe can be protected while being clamped, so as to avoid wear and damage to the air intake pipe and ensure the integrity of the finished product.

[0031] Furthermore, a notch 9 is provided on the base 1 between the first limit block 2 and the third limit block 6.
