Description
Technical field
The present invention relates to field of machining, more particularly to it is a kind of for the chamber processing of annular thin wall depth etc. rigidity bearing it is auxiliary
Help device and method.
Background technology
In aerospace industry, cutting task to thin-wall construction it is critical that, especially annular thin wall depth chamber is cut
Cut the problem for always fabricating.Cavity thin-wall in annular thin wall depth cavity configuration in space structure, such as casing of engine are more
Structure, in order to reduce processing and assembling mode caused by error accumulation influence component precision, now using overall construction design, one
Body formula processing technology, using the big cutter for overhanging, cuts the inner chamber such as casing thin-wall construction.Many annular thin wall deep cavity shell parts
The processing that class part has the characteristics of material cutting ability is poor, and system rigidity is poor, required precision is high, annular thin wall depth chamber is existed
The phenomenons such as very big problem, thin-wall construction work in-process can be deformed, resilience, there are problems that allowing knife, cause workpiece
Deformation, influence workpiece size precision, cutting surface quality and processing efficiency.
The problems such as machining deformation, flutter for inner chamber thin-wall construction process, lot of domestic and international scholar has carried out phase
Close research.
In terms of optimization processing technology, bravely waited in will and proposed using modes such as spark efficient discharging milling and Electrolyzed Processings
Substitute traditional multi-axis NC milling technique；Arnaud gives the optimal cutting environment ginseng for ensureing precision and surface quality
Number；Campa is proposed and is estimated that the method for workpiece stable region avoids flutter；Feng state sleeve etc. proposes to pay attention to the offline volume of digital control processing
Cheng Huanjie, Advanced Control Software shortens amendment and the time difference for compensating in processing；Li Shan etc. proposes to combine digitlization condition optimizing
Machining process route, seeks to process the breakthrough of problem at aspects such as numerical control programmings；Li Guoming etc. is proposed according to inner chamber thin-wall construction
The feature of part is repartitioned to manufacturing procedure, optimization processing technology.But, simple internal cavity thin-wall structure processing technology it is excellent
Change is can not fundamentally to solve thin-wall construction poor rigidity, yielding problem, also involved cutting parameter adjustment
It is excessively complicated, it is impossible to grasp.
In terms of continuous system vibration suppression, Kolluru is proposed for workpiece pastes passive damping, so as to minimize processing
The theory of vibration；Yang proposes to adhere to eddy current damping device in workpiece surface；Meriut proposes to install vacuum cup for workpiece, subtracts
Small machining deformation；HamaedMoradi etc. proposes that, using adjustable damper (TVA), regenerative vibration can be suppressed.But, for processing
Face is for for the thin-wall construction of inner chamber, the installation site of passive damping can not accurately determine, damper etc. is difficult in the narrow and small sky in inner chamber
Between middle application, therefore these methods and theory are not suitable for many inner chamber thin-wall constructions.
There is clearly disadvantageous and limitation in traditional inner chamber thin-wall construction supporting auxiliary, cannot adapt to modern high-precision
Spend the requirement of processing.Traditional inner chamber thin-wall construction supporting householder method has：1. sandbag method is placed in inner chamber；2. wax method is filled；3. paste
Yielding rubber band method etc..
In order to increase rigidity when casing intra vane is processed, inner chamber is used earliest and is placed in sandbag method supporting auxiliary
Chamber, this method efficiency is very low, even if cost is than relatively low, but support effects are not highly desirable, and the sand in sandbag can not
Firmly so as to remain supporting shape, sandbag easily relaxes, deformation, loses the ability of supporting auxiliary for compacting, therefore, inner chamber is placed
The method of sandbag is gradually eliminated.
In order to increase rigidity when casing intra vane is processed, inner chamber is fixed using the method toward filling wax in casing afterwards,
Will the wax of solid-like melt at high temperature, pour into inner chamber and shake up, make wax uniform fold cavity wall, play in fixed inner chamber increases
This method efficiency in chamber is very low, fill wax, wax melting, cleaning residual wax time is more long, high cost, have unqualified hair during part
Life, and have the residue of a small amount of wax in casing, quality is influenceed, therefore, the method for filling wax is gradually eliminated.
In order to increase rigidity when casing intra vane is processed, inner chamber is improved using the method for patch yielding rubber band followed by
Rigidity and resistance to deformation ability, i.e., yielding rubber band have very strong elastic and viscosity, inner chamber thin-wall construction can be attached to
On, using the tension-stretched thin-walled of itself, so as to weaken flutter, reducing machining deformation, this method efficiency is also very low, to thin
The surface cleanness requirement of wall is higher, and yielding rubber band not reusable edible, and capital consumption is relatively more.
The traditional inner chamber thin-wall construction supporting householder method of three of the above cuts both ways, but it is low to there is universal efficiency, effect
Really undesirable the characteristics of, replaced by emerging supporting ancillary technique.
Be present clearly disadvantageous and limitation in modern inner chamber thin-wall construction supporting auxiliary, still need to be improved.
Such as application in 07 month 2011, application publication number was that the patent of invention of the A of CN 102248380 proposes sinking support
Method carries out the supporting auxiliary of inner chamber thin-wall construction.The invention discloses a kind of sinking support method, it is mounted in magnetic molecule
In one soft cloth bag larger than machined thin-walled channels, soft cloth bag is placed in machined inner chamber, with hand is by reality and seals
Mouthful；Apply an external magnetic field to magnetic-particle, it is mutually inhaled together, supporting role is played during processing, after machining again
Apply a rightabout external magnetic field, magnetic-particle is lost magnetism, such that it is able to take out support.Although sinking support method
In, magnetic grain can interact in magnetic field, form non-yielding prop, improve the rigidity of thin-wall construction in process, but
It is not avoided that the generation of flutter；And this invention cannot ensure that the intracapsular all of magnetic grain of annular cloth is seamless and be adjacent to one
Rise, therefore the rigidity bearing such as cannot realize；This invention requires that processing environment must have the uniform magnetic field that can produce particular orientation,
So that the application places of this invention are limited；The equipment in generation magnetic field needed for this invention is difficult voluntarily to build, need to be by purchasing
Mode realizes, which increases the fund input of production, have impact on productive profit.
Such as application in 03 month 2012, application publication number was that the patent of invention of the A of CN 102691740 is proposed using elasticity

And it is separately mounted to the support plate assembly at elastic rubbery body short transverse two ends, and elastic rubbery body build-in cavities, it is at least wrapped
Include and enclose the side wall for being located at its periphery, the lug boss of a bending laterally is formed on the side wall, the different radial direction of elastic rubbery body is cut
The side wall radius that face is intercepted is started to be gradually reduced to the two ends of elastic rubbery body from lug boss.Although elastic bearing of the invention
Rationally, than more uniform, deformation is axial consistent with it during stress, and horizontal beat will not occur for stress for assembly structure, when in use,
What need not be continued is inflated, and production and use cost are relatively low.But the complex structure of this elastic bearing, parts are more,
It is difficult batch production；Containing nearly 90 degree of bending structure in this structure, bending part stress concentration is the brightest during normal operation
It is aobvious, so bending structure is the most weak position for being also to be easiest to breakage in the structure that this is invented；Again because this invents what is used
Filled media is air, and the pressure effect of air acts on inwall, and this bending part subjects shear stress and tension is made a concerted effort
Maximum, the life-span for further resulting in this elastic bearing greatly shortens.Also, the levelness of this invention supporting plane is by rubber
What the rigorous of plastic structure size ensured, so the high-precision requirement of physical dimension inevitably results in the difficulty of processing of product
Increase or be processing disqualification rate rising.

Shape is processed into a kind of plastic cement damping unit, and damping unit is encased the thin-wall construction of 80%-100%, the position for needing processing
Put and reserve, stabilization is ensured by elastic tensioning or installation pin between each damping unit；The casing internal lobe invented using this
Piece processes damping unit to produce damping without cleaning casing and its internal structure and environment friendly and pollution-free, lowers significantly
The manufacturing cost of casing, improves the qualification rate of casing finished product.But, because the application of this damping unit invented is preceding
It is that casing needs to beat location hole to carry, and the required precision of location hole is high, increases the complexity of operation in casing mechanical processing process
Property, the height suitable for the technical merit requirement of workman, labour intensity is than larger, easily error.And each workpiece is required for
Carry out pretreatment and beat location hole, increased considerably workload, while also increasing the working strength of workman, reduce processing effect
Rate, causes mismachining tolerance to become big and uncontrollable, and machined surface quality and machining accuracy cannot be guaranteed.The installation of damping unit
Process is comparatively laborious, influences processing efficiency；The machine-shaping of damping unit stills need precision higher, damping unit and thin-walled
Install and depend on the crudy of damping unit with the complexity of dismounting, therefore be doomed damping unit and occurred with thin-walled
Tightly, excessively loose, just three kinds of situations, may bring inevitable problem to processing.
Such as in November, 2015 application, application publication number is that the patent of invention of the A of CN 105290836 is proposed using upper and lower
Baffle ring clamping elastic rubber ring carries out the supporting auxiliary of inner chamber thin-wall part.The present invention discloses a kind of big overhanging casing zero of narrow space
