The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
For the precision that can realize the rear radome fairing of processing can meet customer requirement, by long-term processing experiment and analysis and summary, we have invented for processing (adopting classic method) spherical radome fairing of high accuracy and have used novel polishing mould.
As shown in Figure 1, mould of the present utility model comprises die ontology 1 and the cylindric substrate 2 with curved surfaces, between die ontology 1 and cylindric substrate 2, is coaxial configuration, and axiality is less than 0.02mm.Main strict two parameters, that is: the height H of die ontology and the radius of curvature R of die ontology controlled of design of this mould.As shown in Figure 2, there is corresponding geometrical relationship with the radius of curvature of the spherical radome fairing 3 (workpiece) that will process in the radius of curvature of die ontology 1, the radius of curvature R of die ontology 1 meets relation: R=R1-b, wherein, R is the radius of curvature of workpiece 3, and b is the thickness of polishing glue-line 4; The height H of die ontology 1 meets relation: H=H1+h-b, and wherein, H1 is the rise of workpiece 3, and h is the distances of workpiece 3 lower ends, edge apart from die ontology 1 bottom, and b is the thickness of polishing glue-line 4.In two relational expressions, h and b are fixed constant: h=5mm, b=10mm.The physical dimension of cylindric substrate depends primarily on the jointing specification of use equipment.
Using method of the present utility model is: mould is arranged on lathe, carries out polishing glue-line.Workpiece is adhesively fixed on mould, notes the symmetry of bonding work pieces, control the variation of rectification cover type by changing the amplitude of fluctuation of workpiece on lathe.Guaranteeing to have under the prerequisite of good axiality after mould is installed on lathe, can process high-precision spherical radome fairing product.
Adopt the utility model to process spherical radome fairing, can meet the technical requirement of high-precision spherical radome fairing.In batch production process, can be good at control centre's thickness, face type and edge thickness difference, avoided affecting because die parameters is improper the problem of radome fairing machining accuracy; Within the scope of all can be controlled at+0.05mm of the center thickness of the radome fairing after processing, face type can reach 1 wavelength, and edge thickness difference can be controlled within the scope of 0.03mm, can meet the requirement of radome fairing high precision technology completely.
The utility model is applicable to the ball-type radome fairing processing of various materials; in the time of the spherical radome fairing of work brittleness material; selection has certain flexible material and makes mould, can play a protective role to workpiece, has avoided because of workpiece and the mould problem of damaging that collides.The utility model simplicity of design, handling ease, cost is low, can reuse, and for processing brings great convenience, has increased substantially production efficiency.
