As shown in Figure 1, in the present embodiment, the cutter head intake of guide sleeves 401 is provided for that cutter head 301 is made to slide along the conical surface
The tapered opening entered.
The Wall-Thickness Difference of the elongated shaft-like work of the present embodiment controls and repaiies inclined processing equipment, method, includes the following steps：To thin
Long axis workpiece 5 is jacked up using both ends and the installation way of center rest support is gripped；Using numerical control deep-hole drilling equipment into
Row drilling and reaming processing；According to the different pore size size in elongated shaft-like work 5, using ultrasound wall thickness and straightness instrument
The mode of eccentricity checks the deflection situation of endoporus, by timely repairing partially, to ensure the concentricity between stepped hole, Jin Erxiu
The just elongated each segment process area in 5 outer surface of shaft-like work and 5 each inner bore of step of elongated shaft-like work are coaxial；In numerically controlled lathe work
Sequence is fixed by way of carrying out both ends clamping and center rest support process area to elongated shaft-like work 5, carries out elongated shaft work
The external form turning of part 5, and using centre frame follow up turning, ensure elongated shaft-like work 5 any cross-section radial thickness consistency,
Meet thickness difference requirement.
In the present embodiment, when the step hole machined of elongated shaft-like work 5,5 both ends of elongated shaft-like work are held out against using two cone disks
Outer chamfer.The medium position of elongated shaft-like work 5 is clamped using cone disk self-centering, and using the centre frame that numerically-controlled machine tool carries,
To enhance the processing rigidity of elongated shaft-like work 5.The bore entrance end of elongated shaft-like work 5 guides cutter head 301 using guide sleeves 401,
301 play of cutter head when preventing drilling from starting and cause the central shaft hole of the elongated shaft-like work 5 processed with outside elongated shaft-like work 5
Circle is not coaxial, causes 5 wall unevenness of elongated shaft-like work even；By the shock-absorbing functions of bakelite set and shock-absorbing sleeve 403, processing knife is improved
Stability when 3 processing of tool.In numerically-controlled machine tool process each process area that table monitors elongated shaft-like work 5 is made with dial gauge
Outer circle jitter values change.The pressure for adjusting two cone disks to elongated shaft-like work 5 according to tabular value is beaten, to prevent elongated shaft workpiece 5
Flexural deformation in process.
When implementation, using numerical control deep-hole drilling equipment, and using both ends jack-up, the installation way of center rest support, bored
The processing such as hole, reaming, and according to different pore size size, checked in such a way that ultrasound wall thickness or straightness instrument survey bias interior
The deflection situation in hole ensures the concentricity between stepped hole, and then amendment process area and inner bore of step are same by timely repairing partially
Axis.Then external form turning is carried out by clamping, center rest support process area in several turner sequences, and using centre frame follow-up turning
Measure, ensure part any cross-sectional wall thickness consistency, to meet Wall-Thickness Difference requirement.
As shown in Figure 1, holding out against part using two cone disks (tailstock side cone disk 101, main shaft side bore disk 102) when step hole machined
Both ends outer chamfer eliminates the time of clamping centering, and carry centre frame (branch using lathe using cone disk self-centering feature
Support mechanism 2) holding parts (elongated shaft-like work 5) stage casing process area (position among the part), enhance part (elongated shaft work
Part 5) processing rigidity.Bore entrance end then uses guide sleeves 401 to guide cutter head 301, when preventing drilling from starting, 301 play of cutter head
And cause processed hole coaxially not even so as to cause wall unevenness with outer circle.And pass through bakelite set (supporting sleeve 402), shock-absorbing sleeve
403 shock-absorbing functions improve the stability of tool sharpening.In addition, it is (elongated to play table monitoring part with dial gauge in process
Shaft-like work 5) variation of each process area outer circle jitter values, suitable pressure is adjusted, prevents part (elongated shaft-like work 5) from processing
Flexural deformation in the process.
For single through-hole, inclination when reducing deep hole machining and part (elongated shaft-like work 5) flexural deformation, you can protect
The uniform wall thickness of card drilling outlet end, can also be by eccentric vehicle to foreign round, to reach outer even if drilling outlet end wall thickness ununiformity is even
Circle is with female coaxial to ensure Wall-Thickness Difference.
And for step deep hole, then it is complex.When processing first deep hole, it is necessary to be carried out on the basis of first hole
It timely repaiies and ensures that outer circle process area and both ends outer chamfer and first deep hole are coaxial partially, then use single through-hole processing scheme
Continue to process second deep hole, ensure the concentricity between holes, and so on processing third, the 4th ... deep hole, to
The final Wall-Thickness Difference ensured after part deep-hole processing.Therefore, the control of the Wall-Thickness Difference of step deep hole is divided into two major classes：
1, can mechanical measurement elongated shaft deep hole machining Wall-Thickness Difference control and repair partially
For being relatively large in diameter, generally in the step hole machined of 20mm or more, we are using Instrument for Straightness to having added
Work hole exits end measures, and on the basis of justifying process area in addition, the tilt quantity in machined hole is calculated according to metric results, then
By on center lathe artificial eccentric turning is carried out to process area, both ends outer chamfer, ensure outer chamfer and machined hole
Concentricity then processes next hole, to ensure the Wall-Thickness Difference after step deep hole machining.
2, can not mechanical measurement elongated shaft deep hole machining Wall-Thickness Difference control and repair partially
For in 20mm step deep hole machinings below, conventional straightness instrument measuring staff can not enter directly to measure.This
When we select to measure machined hole exits end using ultrasonic thickness measurement mode, calculated and added according to surveyed wall thickness value
The tilt quantity in work hole.Again by center lathe, for artificial eccentric to process area, the progress turning of both ends outer chamfer, guarantee is outer
The concentricity of chamfering and machined hole then processes next hole, to ensure the Wall-Thickness Difference after step deep hole machining.
Thin-wall long and thin axis complicated appearance turning Wall-Thickness Difference controls
By taking the power turbine shaft of certain typical turbo oar engine as an example, part overall length 1409.2m, maximum outer circle Φ
78.4, minimum outer circle Φ 24, minimum wall thickness (MINI W.) is only 4.4, and the soft chip breaking of part material is poor.Easily shake knife and curved in process
Song deformation, can not ensure so as to cause Wall-Thickness Difference 0.05.Wall-Thickness Difference in order to control, using centre frame follow-up turning during several vehicles
Measure, enhancing part processing rigidity, reduction shakes knife, ensures uniform wall thickness after smart car is complete.
Turning is carried out by dividing the work to walk outer mold surface being segmented, and first processes the big outer circle of gauge diameter size (because first adding
Work minor diameter outer circle can weaken part rigidity), in each manufacturing procedure, the centre frame work of any close from turning position as possible
Skill platform, to enhance part processing rigidity.Outer mold surface is processed in place by repeatedly moving centre frame.Table monitoring is played in process
Process area adjusts suitable pressure, flexural deformation during holding out against of mode part.By the above measure, it is curved to reduce part
Song deformation, to ensure part Wall-Thickness Difference.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
