The Wall-Thickness Difference of the slender axles workpiece of the present embodiment controls and repaiies inclined processing equipment, method, comprises the following steps: adopt the installation way of two ends jack-up and center rest support to grip to slender axles workpiece 5; Numerical control deep-hole rig is adopted to carry out boring and reaming processing; According to the different pore size size in slender axles workpiece 5, the mode of ultrasound wall thickness and the linearity instrument lateral deviation heart is adopted to check the deflection situation of endoporus, by repairing partially timely, to ensure the axiality between stepped hole, and then it is coaxial with each inner bore of step of slender axles workpiece 5 to revise each sections process area of slender axles workpiece 5 outer surface; In numerically controlled lathe operation, be fixed by the mode of carrying out two ends clamping and center rest support process area to slender axles workpiece 5, carry out the external form turning of slender axles workpiece 5, and adopt centre frame follow-up turning, ensure the uniformity of slender axles workpiece 5 at arbitrary cross-section radial thickness, meet thickness difference requirement.
In the present embodiment, the stepped hole of slender axles workpiece 5 adds man-hour, adopts two cone dishes to hold out against chamfering outside slender axles workpiece 5 two.Utilize the self-centering of cone dish, and the medium position of the centre frame utilizing Digit Control Machine Tool to carry clamping slender axles workpiece 5, to strengthen the processing rigidity of slender axles workpiece 5.The bore entrance end of slender axles workpiece 5 adopts guide sleeves 401 to guide cutter head 301, cutter head 301 play when starting to prevent boring and cause the central shaft hole of processed slender axles workpiece 5 and slender axles workpiece 5 cylindrical disalignment, cause slender axles workpiece 5 wall unevenness even; By bakelite cover and the shock-absorbing functions of shock-absorbing sleeve 403, raising process tool 3 adds the stability in man-hour.Play each process area cylindrical jitter values change of table monitoring slender axles workpiece 5 with dial gauge in Digit Control Machine Tool process.Two cone dishes are adjusted to the pressure of slender axles workpiece 5, to prevent slender axles workpiece 5 flexural deformation in process according to beating tabular value.
During enforcement, adopt numerical control deep-hole rig, and adopt the installation way of two ends jack-up, center rest support, carry out holing, the processing such as reaming, and according to different pore size size, adopt ultrasound wall thickness or linearity instrument to survey the deflection situation that eccentric mode checks endoporus, by repairing partially timely, ensure the axiality between stepped hole, and then it is coaxial with inner bore of step to revise process area.Then in several turner sequence by clamping, center rest support process area carries out external form turning, and adopts centre frame to follow up the measure of turning, ensure that part is in the thick uniformity of arbitrary cross-sectional wall, thus meet Wall-Thickness Difference requirement.
As shown in Figure 1, stepped hole adds and adopts man-hour two cone dishes (tailstock side cone dish 101, main shaft side cone dish 102) to hold out against chamfering outside part two, utilize cone dish self-centering feature, eliminate the time of clamping centering, and utilize lathe to carry the process area (near part middle part) in centre frame (supporting mechanism 2) holding parts (slender axles workpiece 5) stage casing, strengthen part (slender axles workpiece 5) processing rigidity.Bore entrance end then adopts guide sleeves 401 to guide cutter head 301, when preventing boring from starting, and cutter head 301 play and cause institute's machining hole with cylindrical disalignment thus cause wall unevenness even.And by the shock-absorbing functions of bakelite cover (support set 402), shock-absorbing sleeve 403, improve the stability of tool sharpening.In addition, in process, play the change of table monitoring part (slender axles workpiece 5) each process area cylindrical jitter values with dial gauge, adjust suitable pressure, prevent part (slender axles workpiece 5) flexural deformation in process.
For single through hole, reduce inclination during deep hole machining, and part (slender axles workpiece 5) flexural deformation, the uniform wall thickness of the boring port of export can be ensured, even if boring port of export wall unevenness is even also by eccentric car to foreign round, to reach cylindrical and female coaxial thus to ensure Wall-Thickness Difference.
And for step deep hole, then comparatively complicated.When processing first deep hole, must with first hole for benchmark repair timely partially ensure cylindrical process area and two outside chamfering coaxial with first deep hole, then single through hole processing scheme is adopted to continue processing second deep hole, ensure the axiality between holes, process the 3rd, the 4th by that analogy ... deep hole, thus the Wall-Thickness Difference after the processing of final guarantee part deep-hole.Therefore, the Wall-Thickness Difference of step deep hole is controlled to be divided into two large classes:
1, the slender axles deep hole machining Wall-Thickness Difference of mechanical measurement can control and repair partially
Larger for diameter, generally add man-hour at the stepped hole of more than 20mm, we adopt Instrument for Straightness to measure the machining hole port of export, round process area is benchmark in addition, calculate the tilt quantity of machining hole according to metric results, then by eccentric artificial on engine lathe, turning is carried out to chamfering outside process area, two, ensure the axiality of outer chamfering and machining hole, then process next hole, thus ensure the Wall-Thickness Difference after step deep hole machining.
2, the slender axles deep hole machining Wall-Thickness Difference of mechanical measurement can not control and repair partially
For when the step deep hole machining of below 20mm, conventional linearity instrument measuring staff cannot be entered directly measurement.Now we select to adopt ultrasonic thickness measurement mode to measure the machining hole port of export, calculate the tilt quantity of machining hole according to surveyed wall thickness value.By eccentric artificial on engine lathe, turning is carried out to chamfering outside process area, two equally, ensure outer chamfering and the axiality of machining hole, then process next hole, thus ensure the Wall-Thickness Difference after step deep hole machining.
Thin-wall long and thin axle complicated appearance turning Wall-Thickness Difference controls
For the power turbine shaft of certain turbo oar engine typical, this part overall length 1409.2m, maximum cylindrical Φ 78.4, minimum cylindrical Φ 24, minimum wall thickness (MINI W.) is only 4.4, and the soft chip breaking of part material is poor.Very easily to shake in process cutter and flexural deformation, thus cause Wall-Thickness Difference 0.05 to ensure.For controlling Wall-Thickness Difference, in several car process, adopting the measure of centre frame follow-up turning, strengthening part processing rigidity, reducing to shake cutter, ensure the complete rear uniform wall thickness of finish turning.
By a point work step, turning is carried out in outer mold surface segmentation, and first process the large cylindrical of bar portion diameter dimension (because first process minor diameter cylindrical, part rigidity can be weakened), in each manufacturing procedure, centre frame is any process area from turning position close to as far as possible, processes rigidity to strengthen part.By repeatedly moving centre frame, outer mold surface processing is put in place.Beat table monitoring process platform in process, adjust suitable pressure, mode part is holding out against flexural deformation in process.By above measure, reduce workpiece bending deformed, to ensure part Wall-Thickness Difference.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
