Description
Technical field
The present invention relates to the secondary face manufacture method of a kind of light body broadband ring-focus antenna in the communications field, be specially adapted to be operated in high band mobile communication, onboard satellite communication station ring-focus antenna, can move the satellite communication station ring-focus antenna as high accuracy, big rigidity, light weight, the fast manufacturing of the secondary face of ring-focus antenna of taking down the exhibits, and may extend into the manufacturing of the primary reflection surface of antenna.
Background technology
Requirement by the secondary face distinctive appearance of ring-focus antenna, at present at the secondary face of ring-focus antenna of the communication equipment of high band operation, particularly have only traditional foundry machinery processing method, but there is some defective in it in performance and operation in the secondary face manufacture method of mobile communication ring-focus antenna:
Traditional casting processing method, though the secondary face blank with casting can process desirable stiffness and precision, but because mach technological requirement makes final secondary face product have very big weight, even can reach tens kilograms, constitute the key technology weakness of mobile reflector antenna in the dismounting operating process, the requirement of the extremely incompatible antenna of fast taking down the exhibits.
Summary of the invention
The objective of the invention is to avoid the weak point in the above-mentioned background technology and provide a kind of with the secondary face blank of aluminium alloy, the mucilage carbon fibrous composite, fill sandwich material and process the secondary face manufacture method of light body broadband ring-focus antenna, and the inventive method is made not only precision height of the secondary face of antenna, its weight is also very light, has only about 1/10th of conventional cast processing, the present invention has also that material is compound firmly, manufacturing process is simple, good looking appearance, characteristics such as easy for installation, is particularly suitable for various dismounting and moves the secondary face manufacturing of ring-focus antenna.
The object of the present invention is achieved like this, the present invention includes step:
1. use the secondary face blank 1 of casting technique cast aluminium alloy material ring-focus antenna;
2. on the secondary face blank 1 of ring-focus antenna, design the secondary face datum curve 2 of ring-focus antenna, the reflecting surface back side at the secondary face blank 1 of ring-focus antenna forms secondary face benchmark curved surface 3 by secondary face datum curve 2 machinings;
3. the carbon fibre composite of sticking system one deck 0.3 to 3 millimeters thick on secondary face benchmark curved surface 3 forms secondary face compound curved surface layer 4;
4. on secondary face compound curved surface layer 4 upper end actinal surface, glue the carbon fibre composite of system one deck 0.3 to 3 millimeters thick, form the compound facing layer 5 of secondary face, form cavity body structure between secondary face compound curved surface layer 4 and the compound facing layer 5 of secondary face, fill polyurethane expanded material or filling aluminum matter honeycomb interlayer, frp honeycomb interlayer 6 in the cavity body structure;
5. process the reflecting surface of the secondary face blank 1 of ring-focus antenna by the theoretical curve precision optical machinery of the secondary face of design ring-focus antenna, form the secondary face reflecting surface 7 of ring-focus antenna, finish the secondary face manufacturing of light body broadband ring-focus antenna.
The aluminum alloy materials thickness of the secondary face reflecting surface 7 of ring-focus antenna of the present invention is 0.3 to 4 millimeter.
The present invention compares with background technology has following advantage:
1. the present invention has overcome the deficiency of conventional fabrication processes, adopted and had high modulus carbon fiber polymer matrix composites and polyurethane expanded material, or aluminium matter or frp honeycomb interlayer are done the stiffness basis of the secondary face of ring-focus antenna, make the thickness of aluminium matter working surface layers of secondary face can accomplish 0.3～4 millimeter, not only stiffness is good for the secondary face of entire antenna, be out of shape little, the precision height, and weight also has only about 1/10th of conventional cast technology, can satisfy the motor-driven collection operation of antenna well, can reduce the moment of inertia of antenna again widely, help the servo tracking of antenna system.In addition, coordinate, make its aesthetic appearance stronger, install and use more just because secondary face overall dimensions changes.
2. the present invention has adopted carbon fibre composite and metallic aluminium complex technique, not only rigidity is big, in light weight to make secondary face, the full aluminium matter structure that has also crucially kept its working face, not only can satisfy the requirement of secondary face polymorphic structure, and can adapt to the full frequency band electric requirement of ring-focus antenna admirably, especially also have the irreplaceable characteristics of other material-structures at high band, its processing technology may extend into the manufacturing of the primary reflection surface of antenna.Advantages such as it is simple that the present invention also has manufacturing process, and cost is lower.
