And spaces are arranged between adjacent disc-shaped supporting plates, and all the disc-shaped supporting plates are arranged in the combustion chamber shell and used for supporting the combustion chamber shell to avoid deformation during heat treatment.
The further technical scheme is that the top sealing plate and the bottom sealing plate are both provided with through threaded holes, and the threaded holes are parallel to the rotation axis of the combustion chamber; the outer diameter of the disk-shaped bracing plate is equivalent to the inner diameter of the combustion chamber shell. The combustion chamber shell is in a cylindrical shape with central symmetry; the screw hole is parallel to the rotation axis of the combustion chamber, so that the disc-shaped supporting plate arranged on the screw rod can be guaranteed to be perpendicular to the rotation axis of the combustion chamber, the disc-shaped supporting plate can be perfectly attached to the inner wall of the shell of the combustion chamber before heat treatment, and the deformation caused by heat treatment is avoided.
Further technical scheme is, the hoisting ring passes through bolt fixed connection and puts at the top shrouding central point, and the disc fagging is equipped with eight altogether, and the screw rod is equipped with four, and annular array is equipped with four screw holes with the screw rod adaptation on top shrouding and the bottom shrouding, be equipped with the screw thread through-hole with the screw rod adaptation on the disc fagging. The hoisting ring is used for hoisting the tool during heat treatment, so that the combustion chamber shell is subjected to heat treatment in a vertical and naturally drooping state, and deformation generated during heat treatment can be better avoided. The arrangement of a plurality of screws ensures that the disc-shaped supporting plate is more accurately vertical to the rotation axis of the combustion chamber shell.
The further technical scheme is that the length of the screw is 2180mm, the outer diameter of the disc-shaped supporting plate is 195mm, the thickness of the disc-shaped supporting plate is 5mm, and a ventilation circular hole is formed in the center of the bottom sealing plate and has the aperture of 100 mm. The ventilation round holes can ensure the circulation of air inside and outside the combustion chamber shell, and avoid influencing the heat treatment process.
The utility model has the advantages and the beneficial effects that: the shape of the high-strength and ultra-large length-diameter ratio thin-wall combustion chamber shell can be ensured before heat treatment, deformation in the heat treatment process is avoided, and the required smooth finish is achieved. The combustion chamber shell is in a cylindrical shape with central symmetry; the screw hole is parallel to the rotation axis of the combustion chamber, so that the disc-shaped supporting plate arranged on the screw rod can be guaranteed to be perpendicular to the rotation axis of the combustion chamber, the disc-shaped supporting plate can be perfectly attached to the inner wall of the shell of the combustion chamber before heat treatment, and the deformation caused by heat treatment is avoided. The hoisting ring is used for hoisting the tool during heat treatment, so that the combustion chamber shell is subjected to heat treatment in a vertical and naturally drooping state, and deformation generated during heat treatment can be better avoided. The arrangement of a plurality of screws ensures that the disc-shaped supporting plate is more accurately vertical to the rotation axis of the combustion chamber shell. The ventilation round holes can ensure the circulation of air inside and outside the combustion chamber shell, and avoid influencing the heat treatment process.
