Description
Technical field
The present invention relates to hollow shaft manufacture field, especially, it is related to a kind of hollow shaft processing method.
Background technology
In Aeroengine Design manufacturing process, thin-walled hollow axle of the processing as shown in accompanying drawing Fig. 1 is often needed.Existing processing
The process program of the hollow shaft is followed successively by：Neck bar --- quenched --- rough turn --- deep hole machining --- semifinishing --- electricity
Machining small --- nitridation --- machining benchmark --- fine grinding --- magnetic Non-Destructive Testing --- inspection storage.Existing processing side
Case has the following disadvantages：
1) part high processing costs：Deep hole machining is bored using numerical control deep-hole, the apparatus expensive, and cutter for same is cold in high pressure
Drill bit, drill bit is expensive；Small hole machined is processed using accurate digital control electric spark equipment, the apparatus expensive；After electrical discharge machining,
Orifice surface forms weight melting layer, for whether detection weight melting layer exceedes certain depth, it is necessary to every batch of cutting several is melted with inspection again
Layer depth.
2) part passing rate of processing is low：Part semifinishing before nitridation, its integrality preferably, after nitridation, is become by nitridation
Shape influences, and part generation flexural deformation makes linearity in overall length up to 0.2, cause overall acceptability rate there was only 67% or so；And be
The deflection of part is reduced, special stationary fixture clamping parts are specially made, but the deformation of part improves unobvious；Electric spark
After processing, the removal of aperture weight melting layer is ground using axle, and because aperture tolerance is small, and symmetry requirement is tight, grinds
Grind off except weight melting layer might not be removed totally, therefore there is hidden danger of quality.
3) part process cycle is long：Electrical discharge machining efficiency is low, and to reach symmetry requirement, before the processing of each part
With electrode centering repeatedly, process time is increased；Cutting part does weight melting layer depth inspection and is also required to the lathe stand-by period；For
Repair the flexural deformation of part, it is often necessary to reheat school shape；Due to the influence such as part machining deformation, quality after part processing
It is relatively low, it is necessary to pincers worker carries out reprocessing correction.
