Description

Technical Field

[0001] The utility model relates to the technical field of combustion chamber shell support tooling, in particular to a support device for the production and processing of combustion chamber shells. Background Technique

[0002] A combustion chamber is a device in which fuel or propellant burns to generate high-temperature gas. It is a combustion device made of high-temperature resistant alloy materials. The fuel burns in this chamber. It is an important component of gas turbine engines, ramjet engines, and rocket engines. For a piston engine, the combustion chamber refers to the space between the top of the piston and the cylinder head after the piston reaches the top dead center. The combustion chamber of a gas turbine engine is composed of a diffuser, a combustion chamber shell, a flame tube, a fuel nozzle, and an ignition device; it is divided into a single-tube combustion chamber, a manifold combustion chamber, and an annular combustion chamber. The combustion chamber cannot operate under high temperature, large load, variable working conditions, corrosive environment, combustion in high-speed airflow and lean fuel mixture conditions. Therefore, when producing and processing the combustion chamber shell, a support device is needed to place it. The traditional support device is inconvenient to adjust and clamp according to the specifications of the combustion chamber shell during use, and it is also inconvenient to adjust the combustion chamber shell according to the production and processing situation. We propose a support device for the production and processing of combustion chamber shells. Content of the Utility Model
