Solution contacting surface and the contact surface of locating surface and workpiece correspond, with prevent compress deform.
The position degree that blind hole 8121 is respectively relative to datum hole A with through hole 8211 is 0.05, total run-out 0.05；Blind hole
8121 and the specification of through hole 8211 are φ 8 (+0.015,0), and datum hole A specification is φ 34 (+0.025,0).
Datum hole A, blind hole 8121,8211 existing processing method of through hole are：
(1) when processing single-piece first, the datum hole A of the first planet carrier 81 and splined hole B are worked into finished size, it is thick to add
4 blind holes 8121 of work are to 6.8mm, then by four through holes 8211 of the second planet carrier 82 also roughing to 6.8mm；
(2) through hole 8211 of the planet carrier 82 of blind hole 8121 and second of the first planet carrier 81 is alignd, then by the first row
Carrier 81 is welded with the second planet carrier 82；
(3) hydraulically operated fixture tensioner datum hole A is used, is then positioned with the end end face of blind hole 8121, by the first planet carrier 81
Blind hole 8121 is processed into 8mm holes, and the through hole 8211 on the second planet carrier 82 is processed into 8mm through holes 8211；
(4) when processing 8mm holes, processed with two knives, first arrived with milling cutter finish-milling to aperture 7.8mm, then boring cutter right boring
8mm。
Problem points existing for above-mentioned processing method：
A, because of the repetitive positioning accuracy of fixture and datum hole A itself precision, the influence of the deformation of material, blind hole 8121 with
The position degree 0.05 of through hole 8211 ensures difficulty, it is impossible to which 100% is qualified, and defect rate is high；
B, because the first planet carrier 81 and the material of the second planet carrier 82 are inconsistent, blind hole 8121 and through hole in bore hole are caused
8211 diameters are inconsistent, and Aperture uncertainty.
Improved technological process and method are in the utility model：
A, first in the first 81 single-piece work of planet carrier, datum hole A is not worked into finished size, bored after welding combination
Finished size is arrived in reprocessing during bore hole；
B, change fixture positioning when component bores bore hole and clamp benchmark.
Specific is exactly to change traditional thinking mode, after original fixture tensioner datum hole A, reprocesses 4 φ 8mm holes,
It is changed to the big footpath centering (being felt relieved using the feeler gauge of plug-in type spline 721) of spline, the positioning of the end face of blind hole 8121, planet carrier end face compresses
Processing mode.
Procedure of processing after improvement：
(1) when processing single-piece first, splined hole B is worked into finished product, by the datum hole A roughing of the first planet carrier 81,
Four blind holes 8121 of roughing, then by four through holes 8211 of the second planet carrier 82 also roughing；
(2) through hole 8211 of the planet carrier 82 of blind hole 8121 and second of the first planet carrier 81 is alignd, then by the first row
Carrier 81 is welded with the second planet carrier 82；
(3) workpiece is placed on positioning sleeve 9, the end face of the first planet carrier 81 and the end contact of positioning sleeve 9, utilization are blind
The end face in hole 8121 is positioned, and through hole 8211, locating dowel positioning hole 502, the end of alignment pin 6 are sequentially passed through with alignment pin 6
With the end abutment of blind hole 8121；
(4) workpiece is felt relieved with mandrel 7：Mandrel 7 passes through workpiece, and mandrel middle part 72 and splined hole B coordinates, mandrel bottom
73 are deep into the auxiliary section 922 of positioning hole 92；
(5) gland 10 is placed on workpiece, and the pressing plate of paw 11 is pressed on gland 10, and paw 11 will will insert after Work-sheet pressing
Formula mandrel 7 and alignment pin 6 are extracted；
(6) datum hole A is carried out by right boring hole using anti-knife, then process four blind holes 8121 and four through holes 8211 into
Product.
The cutter in processing 8mm holes is optimized simultaneously in last step (6), last work step with the addition of a reamer
It is processed, the uniformity of lower opening and finished product drawing requirement in guarantee.
Position degree report such as Fig. 8 of the workpiece that processes of after-processing technology is improved, the advantages of improving after-processing technology：One
Secondary clamping, datum hole A and 4 planet axis axis holes are processed, position degree 100% can be controlled within 0.05, and is adopted
With the centering of plug-in type mandrel 7, the bounce relation of splined hole and datum hole A is allowed to, can also be ensured.
In summary, thin-walled planet carrier 8 is processed should be noted：
(1), thin wall special-shaped weldment, to the type selecting of cutter and the group of tooling step during planet wheel spindle axis hole is processed
Conjunction property is very high, should take into full account material and the deformation of workpiece；
(2), position degree requires strict product, in machining process is selected, because selecting as far as possible, and the evaluation of position degree
Benchmark and processed hole, time processing come out, and position degree caused by avoiding cumulative errors is unqualified, so as to influence to assemble quality.
(3), the determination of process route will take into full account Technical Economy.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
