Description
Technical field
The present invention relates to mechanical processing industry, the built-up jig of specifically a kind of thin-long casing being less than 2mm for wall thickness.
Background technology
With the continuous development of China's Aeronautics and Astronautics cause, different part gets more and more, and for example certain model is elongated
Thin-wall case.In terms of how the difficult point of this shell workpiece polish mainly effectively controls deformation in clamping workpiece, due to this
Housing is about 2000mm, diameter about φ 120mm, but shell portion wall thickness is only 2mm so that any point contacts or little in processing
The installation way of contact area all can make housing distortion, not only workpiece is caused to damage, and workpiece can be made in clamping state and
Under free state, morpheme size is inconsistent, leads to the dimensional accuracy of workpiece cannot ensure.
In the prior art, generally this workpiece uses technique ring binder, and described technique ring is i.e. at one week of ring-shaped sleeve
Uniform more than 8 radial screw bore, after loading bolt from outside to inside, then installation soft metal makes on the bolt in ring
Arc cushion block, thus a kind of annular clip being formed.After workpiece loads technique ring, make each block grip by adjusting each bolt
Workpiece, and centering can be carried out.This type product still occurs in that many deficiencies when using this technique ring：Technique ring structure is multiple
Miscellaneous, degree of freedom is too high, complex operation during clamping centering workpiece, increased the Operational preparation time；Discontinuity at each cushion block,
Product still can occur different degrees of deformation after clamping；Although each bolt on technique ring can be adjusted during clamping centering
Whole, but the precision required for often not reaching.
Content of the invention
For overcoming the shortcomings of that product present in prior art can occur to deform in various degree after clamping, the present invention proposes
A kind of built-up jig being less than 2mm housing for wall thickness.
The present invention includes tapered sleeve, conical ring, blanking cover and handle；In described built-up jig, conical ring loads the center in the hole of tapered sleeve,
And so that the male cone (strobilus masculinus) of this conical ring is fitted with the inner conical surface of described tapered sleeve；Blanking cover is placed on the end face of described conical ring；Handle fills respectively
In the handle in the hole positioned at described blanking cover surface.
The endoporus of described tapered sleeve is made up of isometrical section and reducer.Described isometrical section is located at this tapered sleeve one end；Described reducing
It is connected with described isometrical section at the maximum gauge of section, be located at the minimum diameter of reducer on another end face of tapered sleeve.Described
Isometrical section of inner surface is flank.The described bus of tapered sleeve reducer and the angle of centrage are 8 °；The minimum of reducer is straight
Footpath is 124mm.
The endoporus of described conical ring conical ring is isometrical hole；The outer surface of this conical ring be the conical surface, and the bus of this conical surface with
The angle of heart line is identical with the bus of reducer in tapered sleeve and the angle of centrage.Cylindrical at described conical ring maximum outside diameter end
Perimeter surface has the pressing plate of radially protruding.Axially open is had on conical ring, this opening extends to the other end from one end of conical ring, and passes through
The housing of logical conical ring, makes conical ring opening-like.The minimum outer diameter of described conical ring is 125mm；The internal diameter of conical ring is 122mm.Described
The width of opening is 10mm.
Described blanking cover is circular, and its external peripheral surface is the flank with the screw-internal thread fit in tapered sleeve.This blanking cover
Internal diameter is 122mm.Symmetrical on the end face of this blanking cover two tapped through holes for install handle are distributed with.
According to the construction featuress of shell workpiece, the present invention proposes for special combination during elongated thin-wall case polish
Built-up jig is reasonably arranged on the non-machine of housing and adds face position, makes blanking cover inward by turning handle by fixture during work,
When conical ring is pressed into tapered sleeve by blanking cover, the conical ring cracking is made to tighten up, thus equably clamping body.
In the present invention, the external form of tapered sleeve is cylinder, and inner mold is coniform hole, and aperture inner circle part has female thread；Conical ring
External form is tapered cylinder, and conical surface size is equivalently-sized with the inner mold face of described tapered sleeve, has protrusion step at the maximum cylindrical place of external form,
Inner mold is through hole, and inner mold through-hole diameter is more bigger than the diameter of product, axially has joint-cutting in conical ring, to realize the receipts of conical ring
Contracting.During clamping, housing to be processed is loaded in built-up jig, the conical ring radial contraction of built-up jig is made by turning handle and presss from both sides
Clamping of workpieces, you can carry out the finishing processing of housing.
Compared with prior art, the present invention achieves following beneficial effect：
(1), after stepping up housing to be processed by the conical ring of built-up jig, this built-up jig is made to be formed with housing to be processed
Overall coordinate relation it is ensured that described built-up jig is coaxial with housing to be processed and stable with lathe holding, eliminates because organizing co-clip
The position error that tool and housing to be processed coaxially do not produce.
(2) pass through the present invention it is achieved that positioning to the face of housing external peripheral surface to be processed, and by chuck to this combination
The three-point fix of fixture, while ensureing housing work in-process stable position to be processed, is treated at this by adjusting built-up jig
The clamping position of processing housing axial direction, it is to avoid the interference to processing for the fixture.
(3) the present embodiment, in the case of ensure that fixture itself rigidity, can make workpiece install stable, uniform force, folder
Tightly reliable, because cutting force, clamping force are deformed minimum during processing.
(4) the present embodiment structure be simple and convenient to operate fast, workpiece uniform force, safe and reliable, can be prevented effectively from
Problem on deformation during tube-like thin-wall clamping, overcomes deficiency of the prior art.
