Description
Technical field
The present invention relates to hollow shaft manufacture fields, particularly, are related to a kind of hollow shaft processing method.
Background technique
In Aeroengine Design manufacturing process, often need to process such as attached drawing thin-walled hollow axis shown in FIG. 1.Existing processing
The process program of the hollow shaft is successively are as follows: neck bar, and --- quenched --- rough turn --- deep hole machining --- semifinishing --- is electric
--- --- --- storage is examined in fine grinding --- magnetic powder non-destructive testing --- to machining benchmark to machining small for nitridation.Existing processing side
Case has the disadvantage in that
1) part processing cost is high: deep hole machining is bored using numerical control deep-hole, and the equipment is expensive, and cutter for same is cold in high pressure
Drill bit, drill bit are expensive；Small hole machined is processed using accurate digital control electric spark equipment, and the equipment is expensive；After electrical discharge machining,
Whether orifice surface forms weight melting layer, be more than certain depth to detect weight melting layer, needs every batch of cutting several to melt again to check
Layer depth.
2) part passing rate of processing is low: part semifinishing before nitrogenizing, integrality is preferable, after nitridation, is become by nitridation
Shape influences, and part, which generates bending deformation, makes straightness in overall length cause overall acceptability rate there was only 67% or so up to 0.2；And it is
The deflection for reducing part specially makes dedicated stationary fixture clamping parts, but the deformation improvement of part is not obvious；Electric spark
After processing, the removal of aperture weight melting layer is ground using axle, and since aperture tolerance is small, and symmetry requires sternly, to grind
It grinds off except weight melting layer may not be able to remove completely, therefore there are hidden danger of quality.
3) part process cycle is long: electrical discharge machining low efficiency, and to reach symmetry requirement, before each part processing
With electrode centering repeatedly, process time is increased；Cutting part does weight melting layer depth inspection and is also required to the lathe waiting time；For
Repair the bending deformation of part, it is often necessary to reheat school shape；Since part machining deformation etc. influences, quality after part processing
It is lower, need pincers worker to carry out reprocessing correction.
