Description
Technical field
This utility model relates generally to the frock clamp of the titanium alloy compressor disc course of processing.
Background technology
The parts such as electromotor mid-game, axle, drum barrel, axle journal are all core rotatable parts and the key components of electromotor, high temperature,
Work under high pressure, high-revolving adverse circumstances.This kind of part material adopts high temperature alloy, powder metallurgy superalloy, titanium alloy mostly
Deng difficult-to-machine material manufacture, dimension precision requirement is high, and technical conditions are strict, and surface quality of workpieces, surface integrity are had high demands,
The height of its crudy directly influences service life and the security reliability of electromotor.Dish axle integrative-structure part is to pass
The compressor disc of system and the important bearing member that becomes one of axle journal, material is titanium alloy, and big end is wheeling disk structure, has wheel
Edge, disc, wheel hub, core hole, wheel rim carry the dovetail slot installing blade, have precision bolt connecting hole at disc.Part
Journal end outer mold surface is threaded, the architectural feature such as tooth of combing, external splines, radial direction inclined hole.Another spy of dish axle integrative-structure part
Point is that axle journal cone wall defines semiclosed deep-small hole structure with wheel disc disc, and processing technology is poor.
After compressor, drum barrel part is to be combined by flywheel friction welding welding by 5 compressor discs, with Pyatyi ring
Shape dovetail slot, disc interior lumen type space of planes is narrow and small, and inner chamber root bottom part radial depth is big, it is poor to open wide property, difficulty of processing is big, outward
Moulding surface structure is complicated, and dimensional accuracy is high, and technical conditions require sternly, and rear drum barrel material is titanium alloy, hardness HB >=388N/mm2.Pass
The processing mode of system, parts size precision relies on the upper tool offset value of operator to control, big by artificial influence factor, dimensional tolerance from
Divergence is big.Generally all carry the tongue-and-groove installing blade on disk drum class part wheel rim, vertical tree-like tongue-and-groove and dovetail can be divided into by shape
Shape tongue-and-groove, is divided into axial tongue-and-groove and annular tongue-and-groove by tongue-and-groove direction again, and axial tongue-and-groove generally adopts wire pulling method, annular dovetail
Groove adopts numerical control workshop.More, the tenon of annular dovetail slot structure is applied on engine compressor disk and drum barrel component
Channel opening is little, inner chamber width, and typically in 0.01 mm, other surfaces profile tolerance is typically 0.025 for tongue-and-groove work surface profile
Mm about, the required precision of manufacture is high, and main processing difficulties are：
（1）Tongue-and-groove work surface node size, position accuracy and true edge diameter dimension tolerance are strict, especially
Tongue-and-groove profile tolerance will ensure on holotype face, and equipment cutter is had high demands, and titanium alloy material machinability is poor, processing hardening phenomenon is tight
Weight, the machining accuracy of impact part and surface quality level.
（2）Tenon groove structure is that chamber is big, mouth is little, and unlimited property is poor, makes that the big neck of tongue-and-groove tool head is little, and cervical region intensity is relatively
Weak, and allowance is larger, chip removal is difficult, easily phenomenon of forging a knife in the course of processing.
Compressor disc by friction welding (FW) or electron beam weldering formed drum barrel molectron after, deep chamber bottom-type face between plate convergence plates at different levels
Processing is always difficult point and bottleneck in processing, and particularly inner chamber radial depth size H is narrow more than the closing of core bore dia φ A
In length, the processing of lumen type face is even more the key in the processing of drum barrel molectron.Because between plate wheel hubs at different levels, spacing C is little, during Tool in Cutting
Blind regarding state under processing it is impossible to observe monitoring cutting situation, processing risk big.Conventional process and cutter cannot complete
The processing of such deep chamber closure profile, can only be processed from longer, thinner thickness the cutter that overhangs, cause cutter poor rigidity,
Intensity is relatively low, easily occurs allowing knife and cuts covibration, aggravate tool wear, after processing, piece surface easily occurs in the course of processing
Chatter mark, difficulty of processing is big.And in the machining of the whole turbine disk, workload is maximum, difficulty highest is that wheel disc chase mortise adds
Work.Variously-shaped complicated circumferential tongue-and-groove commonly uses milling machine milling and broaching machine is broached and to be processed.Because dovetail type tenon groove structure is not advised
Then, complex-shaped, and surface roughness requirements are in more than Ra0.8, according to Milling Process it is necessary to by rough milling, half essence
Milling, finish-milling three road technique, are possible to the surface roughness making tongue-and-groove reach requirement, and high labor intensive, and efficiency is low, processing
Precision is difficult to ensure that, seldom employs in batch production, so adopting wire pulling method more.The broaching of broaching feature is a kind of
In high precision, efficient can final molding machining process, for processing variously-shaped inner and outer surfaces, and have
Helicla flute of rotary motion etc..It is particularly suitable for the part producing in batch and in a large number that machining accuracy is high, surface quality requirements are high.Existing
It is widely used in the processing of the parts such as aero-engine disk at different levels, blade tenon, the turbine disk, compressor disc, installing plate, but
Special cutter, measurer and other accessory must be equipped with.
The unfixing ripe processing method of processing to titanium alloy compressor disc for the prior art.Conventional processing method work
Sequence is many, and frock is many, and the lathe being used is many, and the product size deformation processing is big, and qualification rate is low, takes time and effort；This
Not only production efficiency is low for traditional method, and the product size processing, shape and positional precision, because of relatedness too
By force it is difficult to control；Quality is unstable, is also easy to produce waste product.Engine compressor disk as shown in Figure 1, this compressor disc is large-scale disk
Class thin-walled parts external diameter 527 mm, thinnest part 4 mm, and required precision is very high, is very easy to deformation, traditional manufacturing procedure relates to
And more than 50, need to change 5-10 platform lathe, processing time consuming, qualification rate is only 50%, with the development of Aeronautics and Astronautics industry, right
Product quality requires more and more higher, and this processing method far can not meet the demand of product quality and production efficiency.
