0 + 0.012Angle between the mm, two pin-and-holes is about 60 degree, and is as shown in Figure 6; The center of circle of two pin-and-holes circle of living in does not overlap with the part center of circle; Offset is between 0.8-1.2mm, and after can guaranteeing like this in the postorder operation faying face processed finishing, the center of circle at two pin-and-holes place overlaps with the part center of circle; Adopt the eccentric method of pin-and-hole can solve three casing assemblies of a blank processing; Practiced thrift cost greatly, the main measurer of this step has 0-200mm micrometric depth gauge and 4-9.5mm dial bore gage etc., and capital equipment has MM7132 surface grinding machine and T4163 jig boring machine;
Step 107: with casing lower surface F face is benchmark, and the G face is pressed in the pin-and-hole location; Utilize five coordinate numerical control machining centers to the blade processing of slotting, the groove of a 6mm is opened in fixing orientation of lathe during fluting processing between blade and blade; Stay the 1mm surplus in the runner direction, as shown in Figure 7, can cut off the contact of interlobate internal stress like this; But it is too much that groove should not be opened, and stay surplus as much as possible to blade, for the interval processing method of postorder guarantees; Process faying face place and flange hole at last, guarantee that the diameter in hole satisfies 4
0 + 0.012The requirement of mm, the main measurer of this step has 0-5mm dial gauge etc., and capital equipment has UCP710 five coordinate high-speed machining centers;
Step 108: with casing lower surface F face is benchmark, and the G face is pressed in the pin-and-hole location; Utilize five coordinate numerical control machining centers that the profile of casing is carried out fine finishining (promptly being machined within the scope of error permission, down together), spare part outside measurement is guaranteed by nc program; Carry out the fine finishining of casing profile earlier and be in order to guarantee that distortion that sharp processing causes does not influence the precision of blade; After profile fine finishining, carry out carrying out the fine finishining of blade again after destressing is handled with the rebuilding benchmark, thereby guarantee the processing of leaves precision; The main measurer of this step has 0-5mm dial gauge etc., and capital equipment has UCP710 five coordinate high-speed machining centers;
Step 109: carrying out the timeliness stress removing, before blade fine finishining, carry out secondary ageing and handle, mainly is the internal stress of eliminating processing of blade fluting and the generation of profile fine finishining stage, guarantees the processing of leaves precision;
Step 110: utilize technology precision bolt, nut (also can in adopt the bolt and nut of general precision) that the three equal parts component groups is dressed up a domain; Grinding casing upper surface B and lower surface F once more; And be benchmark advanced study and training dowel holes with upper surface B face, processing datum F and two datum holes all can deform after the timeliness stress removing, and the precision of benchmark is difficult to guarantee; In order to improve the crudy of part; Means through revising benchmark once more realize that the main measurer of this step has 0-200mm micrometric depth gauge and 4-9.5mm dial bore gage etc., and capital equipment has MM7132 surface grinding machine and T4163 jig boring machine;
Step 111: with casing lower surface F face is benchmark; Centering part endoporus; Other surface except that blade, clamping precision turning casing inside at twice, the main measurer of this step has 0-150mm slide measure and 0-5mm dial gauge etc., and capital equipment has the C620 numerically controlled lathe;
Step 112: dismounting precision bolt and nut, whole casing is divided into three part assemblies, be convenient to carry out respectively the blade fine finishining of three assemblies;
Step 113: with casing lower surface F face is benchmark, the pin-and-hole location, and finish-milling blade and faying face, the main measurer of this step has 0-5mm dial gauge etc., and capital equipment has UCP710 five coordinate high-speed machining centers, and concrete steps comprise:
Step 11301: on the basis of blade fluting processing, directly process one, comprising the blade back of leaf basin, runner and the adjacent blades of a blade at a distance from one blade path; Machining the back also has half the blade path to be processed; As shown in Figure 7, arrange this interval processing method can make blade in that the processing of accomplishing leaf basin, runner and blade back under the situation of enough rigidity is arranged, if process blade path continuously; Rigidity can be very poor during blade processing; Can cause very big strain after the processing, mismachining tolerance is generally very inhomogeneous at 0.1-0.2mm and error profile, and is maximum near the error at blade tip place; And at interval the blade error of processing method processing less than 0.03mm, the no chatter mark in surface;
Step 11302: process the fillet up and down of blade respectively, it is that the V of blade surface is to, i.e. cutter runner direction feeding from the blade lateral that fillet adds the man-hour machining direction; As shown in Figure 8, generating tool axis vector curvature along with fillet surface when feeding changes, and generally remains on generating tool axis vector and becomes 15 degree to be advisable with the fillet surface tangent vector; Fillet processing we original what adopt is the layering finishing method, lathe C axle rotational angle is very big when fillet is processed, working (machining) efficiency is very low; Fillet of general processing needs about 30 minutes, and the existing fillet that adopts becomes the slotting milling of axle, selects a kind of flat band R cutter for use; Can increase the diameter of cutter; Reduce and insert the number of times that mills, a general fillet is inserted to mill and can be obtained size and dimension precision preferably about 5 times, and the A axle of lathe and C axle rotate very little during owing to processing; Therefore significantly shorten to 2-3 minute process time, working (machining) efficiency has improved 10 times.
Step 11303: as shown in Figure 9; In the blade path of having processed, adopt the flexible support method, reprocess out second half blade path to be processed, thereby accomplish the fine finishining of whole blade; Shown in figure 10; The flexible support method promptly is contained in a ratio with the magnetic molecule and has processed in the bigger soft cloth bag of blade path, and the soft cloth bag is placed processing channel, with hand by reality and seal mouth.Apply an external magnetic field to magnetic-particle, it is inhaled together each other, add and play a supporting role man-hour, blade can not produce distortion.Apply a rightabout external magnetic field after machining again, magnetic-particle is lost magnetism, thereby take out supporter easily.Because the space between the blade is narrow and small and curve form is complicated, can't adopt rigid support, it is the same with spoon of blade complex-curved to adopt other method for supporting all must process earlier; And the flexible support method that we adopt need not to carry out any processing, and is easy to operate; Support effect is good; The easy operating in the production scene, mismachining tolerance can be controlled between the 0.03-0.05mm, satisfy the requirement of whole casing blade error 0.1mm fully;
Step 11304: finish-milling casing three equal parts faying face; Because there are a little off-centre in dowel hole and part center; The surplus of removing binding face can make the center of circle of two pin-and-holes place circle overlap with the center of part, make casing blade after the assembling be distributed in same in the heart;
Step 114: with precision bolt and nut three part component groups are dressed up the domain, obtain the finished product of whole casing, as shown in Figure 1; We have arranged the secondary ageing stress removing in above operation, and secondary correct grinding machining benchmark is for progressively eliminating the influence of machining deformation to the part processing quality, and we do not arrange these operations to add man-hour at testpieces; Processing back three part assemblies are difficult to assembling; The error that the assembling back is detected is very big, can not meet the demands, on the basis of summing up failure experience; We have arranged these operations, have obtained effect preferably.
The casing that will pass through above-mentioned steps processing detects on three coordinate measuring machine; The result satisfies the designing requirement of casing fully; Especially the worst error of blade-section is controlled at about 0.05mm, and the casing blade error 0.2mm that compares common process processing is significantly increased.
The present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
