The vertical and horizontal split surface gaps of the air inlet chamber are required to be smaller than 0.5mm according to design requirements, and the roundness phi 3 of the circular flange is ensured after the air inlet chamber is welded; a large number of through holes are required to be processed on the vertical bisection surface and the horizontal bisection surface, a large number of screw holes are required to be processed on the two round flanges after the whole welding of the air inlet chamber, and a large number of screw holes and through holes are formed on the air inlet flange for subsequent assembly of the air inlet cylinder and the supporting device.
At present, a horizontal split surface flange is combined on a tool to drill a through hole, and screw holes on the air inlet flange and the flange combined with the air inlet cylinder are machined after the whole air inlet chamber is welded.
The prior art scheme has simpler flow, but has the defects in various aspects such as equipment cost, transfer cost, processing difficulty and the like because the size of the welded air inlet chamber is larger for the re-processing hole after the welding.
If a screw hole is processed in a part state, as the expansion joint is connected between the air inlet chamber main body and the cone, high requirements are provided for the size and the position degree of the screw hole, a large amount of welding deformation can be generated in the air inlet chamber welding process, and the deformation out-of-tolerance exists in the hole position, so that the air inlet chamber main body and the cone cannot be combined.
