Description
Technical field
The utility model relates to a kind of welding combustion chamber fixing tools, belong to airline carriers of passengers auxiliary power unit depth dimension
Repair field.
Background technique
Combustion chamber is the device of fuel or propellant in wherein burning generation high-temperature fuel gas, is a kind of high-temperature alloy material
Expect the combustion apparatus of production, structure is thin wall type hollow cylindrical structure, and one end, which is set, is connected with guide ring.But it is fired in welding
It is easy to cause combustion chamber to deform when burning room, to be unable to meet demand.
Summary of the invention
The purpose of this utility model is to provide a kind of toolings of fixed combustion room in welding, by coming directly towards fixed combustion
Chamber outer wall and the fixed guide ring of support column, to realize the positioning and fixation of combustion chamber.
The utility model is achieved through the following technical solutions：
A kind of welding combustion chamber fixing tool, including pedestal and support column, the pedestal are spill cavity, spill cavity
Interior bottom center is equipped with support column and is provided with fixation hole, and chassis outer side top is uniformly provided with several installation positions, on installation position in
Centre is provided with through-hole, is fixed with and picks up the ears on installation position, picks up the ears to be equipped with top, come directly towards across through-hole；In use, combustion chamber is placed
On pedestal, by adjusting side wall outside the fixed combustion room of top, the guide ring of combustion chamber is fixed on the top surface of support column.
Further, the number of the installation position is 3~5.
Further, the both ends of the support column are integrally formed with ring flange.
The utility model has the advantages that：
(1), not only can be with fixed combustion chamber outer wall by setting top, while combustion chamber can be also positioned, it is subsequent installation
Fuel nozzle connector provides help, convenient for the assembly of final workpiece；
(2) by setting support column, and it is equipped with ring flange on the support columns, passes through the fixed guide ring of ring flange, fix tightly
It leans on；
(3) fixation hole is provided with by pedestal, convenient for part to be mounted on disk machine, is convenient for welding and welding effect is good；
(4) structure is simple, connection is firm and operation is convenient.

Specific embodiment
5 structure of combustion chamber is thin wall type hollow cylindrical structure, and one end, which is set, is connected with guide ring.Such as FIG. 1 to FIG. 4 institute
Show, welding combustion chamber provided in this embodiment 5 includes pedestal with fixing tool：1 and support column 2, the both ends of the support column 2 it is equal
Integrally formed with ring flange；The pedestal：1 is spill cavity, and bottom is provided with fixation hole 11 in concave shaped cavity body, equal around fixation hole 11
It is even to be provided with several threaded holes, for installing support column 2；Pedestal：1 outer upper is uniformly provided with several installation positions 12, installation position 12
Upper center is provided with through-hole 13, is fixed on installation position 12 and picks up the ears 3, picks up the ears 3 to be equipped with top 4, top 4 passes through through-hole 13；Wherein,
The number of the installation position 12 is 3~5.
In use, combustion chamber 5 is placed on pedestal：On 1, by adjusting top 4 fixed combustion room, 5 lateral wall, combustion chamber 5
Guide ring be fixed on the top surface of support column 2, then by pedestal：1 and combustion chamber 5 be mounted on turntable by fixation hole 11,
The velocity of rotation for adjusting turntable is welded.When welding combustion chamber 5, the utility model assembly is easy and secured, supporting & stablizing, weldering
It is good and easy to operate to connect effect.
The above is only the utility model preferred embodiment, but the protection scope of the utility model is not limited to
This, any transformation carried out based on technical solution provided by the utility model and utility model design and replacement should all be covered
In the protection scope of the utility model.
