Description
Technical field
The present invention relates to technical field of mechanical processing more particularly to main AC power source of aircraft combination driving power generating device
The filter core manufacturing field of system, and in particular to a kind of the flaring welding protective device and its application method of stainless steel filter core.
Background technique
Stainless steel filter core be certain aircraft combination driving power generating device main AC power source subsystem attachment, for filter into
Enter the lubricating oil of the system, guarantees the requirement of lubricating oil cleannes, sealed again by both ends end cover inner hole after this Product Assembly, so two
The concentricity of end cover inner hole requiresAnd there is length dimension tolerance between left and right ends to want no more than 0.5
It asks.Again because entire product processing is that first skeleton 1, strainer 2, connection ring 3 are assembled, are flared and are welded into filter core (Fig. 1),
The end cover at both ends is welded again, therefore just has following requirement to filter core:
1,1 both ends of skeleton are flared before welding, so that strainer 2 is tightly attached to the inner hole of connection ring 3, this process middle skeleton 1
It is not allow for unstability;
2, the phenomenon that damage and burn strainer 2 are not allow for when welding, and do not allow spatter, metal fillings on strainer 2
Equal dirts;
3, to guarantee that length dimension tolerance+0.5, two connects interannular between left and right ends after weldingConcentricity is wanted
It asks.
Above-mentioned require is after part passes through combination, to calculate from maximum theoretical, be regular
Property, actually really not so, this is not only influenced by deformation extent and distortional stress is flared on 1 both ends of skeleton after assembling, also
Depending on irregular deformation caused by stainless steel welding stress in each part welding process.
There are many oil-through holes for processing on skeleton 1, reduce the intensity of skeleton 1, are only to be difficult to ensure it by conventional method
Not unstability, there are also length dimension tolerance +s 0.5, two between the left and right ends after welding to connect interannularConcentricity requirement, dress
When with flaring welding, its length dimension, concentricity requirement only are difficult to ensure by conventional assembly flaring, welding.Practical behaviour
It is to be loaded on both ends connection ring 3 first by strainer 2 on skeleton 1, then 1 both ends of skeleton are flared, make itself and 2 liang of strainer in work
End, 3 inner hole of connection ring fit closely together and then are welded as filter core, be flared in this way positioning welding at filter core, when flaring, bone
1 both ends of frame are easy unstability, and length dimension tolerance+0.5, two connects interannular between left and right endsConcentricity requires to guarantee not
, surplus manufacturing procedure is both needed to guarantee that length dimension tolerance+0.5 requires between left and right ends and correction can guarantee just now
Two connection interannularsConcentricity requirement.This process is not only time-consuming, is also difficult to ensure the cleannes requirement of strainer 2, be also flared,
Correction course needs very strong experience, otherwise or is flared not in place or damage strainer 2, influences properties of product and appearance,
Correction is not in place, allows after the upper end cover of welding, can not guarantee size, the status requirement of entire product.Such product, dress
Aboard or sealing is not in place, and leakage occurs or strainer is had damage, influences filtering accuracy, influences the right lubricating oil system of aircraft
It unites and has the possibility for leading aircraft flight failure.
Summary of the invention
