The invention relates to a high-precision assembly tool of a real reflecting surface. The high-precision assembly tool comprises a base rack and is characterized in that a rotating base is arranged on the base rack; the upper surface of the rotating base is the positioning surface of the bottom plate of the reflecting surface; a positioning mandrel is inserted into the center hole of the rotating base; a boss is arranged in the middle of the positioning mandrel; the part, above the boss, of the positioning mandrel is sleeved with a radial ribbed plate calibrating sample plate or a panel shaping sample plate; the outer cambered surface of the radial ribbed plate calibrating sample plate is consistent with the cambered surface of the radial ribbed plate of the reflecting surface; the outer cambered surface of the panel shaping sample plate is consistent with the cambered surface of the panel of the reflecting surface. According to the invention, the base plate, the radial ribbed plate and the panel are fixed on the rotating base by positioning and rotate along with the rotating base, so that an operator does not need to move the base plate, the radial ribbed plate and the panel, the working intensity of the operator is reduced, and the working efficiency is improved; the radial ribbed plate calibrating sample plate and the panel shaping sample plate are used for marking the correct cambered surface of the reflecting surface as well as errors of the panel, and thus a foundation is laid for the follow-up shaping procedure.
Description
Technical field
The present invention relates to the assembly tooling of a kind of high-precision real face reflecting surface, especially a kind of assembly tooling of radar reflection face.
Background technology
Reflecting surface is the core component of radar antenna feeder, and its realization on the main war of radar, skill index has important impact.The assembly tooling of existing real face reflecting surface, is limited by the machining accuracy of panel, is difficult to the precision that reaches high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the assembly tooling of a kind of high-precision real face reflecting surface is provided, assembly structure is simple, easy operating, and can increase substantially reflector precision.
According to technical scheme provided by the invention, the assembly tooling of a kind of high-precision real face reflecting surface, comprises underframe, and feature is: on described underframe, place rotating base, the upper surface of rotating base is the locating surface of reflecting surface base plate; In the centre bore of described rotating base, insert location mandril, the middle part of location mandril arranges boss, sheathed radially gusset aligning template or panel shaping model on the location mandril on boss top.
The outer N-Side surf of described radially gusset aligning template and the reflecting surface radially curved surface of gusset are consistent.
The outer N-Side surf of described panel shaping model is consistent with the curved surface of reflection surface panel.
The present invention compared with prior art, there is following beneficial effect: the present invention is by base plate, radially gusset, panel are fixed on rotating base by location, with rotating base, rotate, thereby do not need operating personnel to move, the working strength that has greatly alleviated operating personnel, has improved operating efficiency; By the location of rotating base, keep panel and correct position relationship between gusset aligning template, panel shaping model radially, so that model indicates correct reflecting surface curved surface, indicate the error of panel, for trimming below lays the foundation.
Accompanying drawing explanation
Fig. 1 is the structural representation of assembly tooling of the present invention.
Fig. 2 is the use view of assembly tooling of the present invention.
The specific embodiment
Below in conjunction with concrete accompanying drawing, the invention will be further described.
As shown in Fig. 1～Fig. 2: as described in high-precision real face reflecting surface assembly tooling underframe 1, rotating base 2, location mandril 3, radially gusset aligning template 4, panel shaping model 5, boss 6 etc.
As shown in Figure 1, the present invention includes underframe 1, place rotating base 2 on underframe 1, the upper surface of rotating base 2 is the locating surface of reflecting surface base plate 10; In the centre bore of described rotating base 2, insert location mandril 3, the middle part of location mandril 3 arranges boss 6, sheathed radially gusset aligning template 4 or panel shaping model 5 on the location mandril 3 on boss 6 tops, radially radially the curved surface of gusset 20 is consistent for the outer N-Side surf of gusset aligning template 4 and reflecting surface, and the outer N-Side surf of panel shaping model 5 is consistent with the curved surface of reflection surface panel 30.
Adopt assembly tooling of the present invention to carry out the method for reflecting surface assembling, as shown in Figure 1
The first step, is fixed on rotating base 2 upper surfaces by reflecting surface base plate 10 use bolts, nut, is determined the position of reflecting surface base plate 10 by the locating surface of the upper surface of rotating base 2;
Second step: by reflecting surface radially gusset 20 carry out pre-assembled with reflecting surface base plate 10 use bolts, nut;
The 3rd step: location mandril 3 is packed in the centre bore of rotating base 2, will be radially gusset aligning template 4 pack on location mandril 3, make reflecting surface radially gusset 20 and the outside application of a surface of gusset aligning template 4 radially;
The 4th step: radially gusset aligning template 4 takes out from location mandril 3;
The 5th step: by reflecting surface radially gusset 20 and reflecting surface base plate 10 use bolts, fastening nuts;
The 6th step: by reflection surface panel 30 and reflecting surface gusset 20 pre-assembled radially;
The 7th step: panel shaping model is filled to 6 and pack on location mandril 3, reflection surface panel 30 and panel shaping model 5 are compared, indicate the error point A of reflection surface panel 30;
The 8th step: the thick shaping of reflection surface panel 30; By hammering, bulging method, the error point A of the reflection surface panel indicating 30 is forced down, make the curved surface of reflection surface panel 30 and the laminating of the positive camber of panel shaping model 5;
The 9th step: by reflection surface panel 30 and radially gusset 20 riveted joint assemblings of reflecting surface;
The tenth step: location mandril 3, panel shaping model 5 are taken out from rotating base 2, by supporting plate, annulus and reflecting surface radially gusset 20, reflection surface panel 30 assemble weldings, make each part form a complete real face reflecting surface;
The 11 step: in the centre bore that location mandril 3, panel shaping model 5 are packed on rotating base 2, reflection surface panel 30 and panel shaping model 5 are compared, indicate surface error point;
The 12 step: reflection surface panel 30 finishing shapes: by hammering, bulging method, the surface error point indicating is forced down, make the curved surface of reflection surface panel 30 and the laminating of the positive camber of panel shaping model 5, guarantee the required precision of reflecting surface.
The present invention adopts panel shaping model and reflection surface panel to compare, indicate the error of reflection surface panel and theoretical curved surface, error point is used to the method for hammering, make error point extension, recessed, it is drawn close to theoretical curved surface gradually, thereby greatly reduced the error of panel, guaranteed the precision of reflecting surface; And in assembling process, the shaping process of reflecting surface is divided into thick shaping and finishing shape two procedures, after whole reflecting surface installation, carries out finishing shape, thereby further improved the precision of reflecting surface; The present invention adopts rotating base, during assembling, the part of reflecting surface can be fixed on rotating base, rotates, thereby do not need operating personnel to move with rotating base, has greatly alleviated operating personnel's working strength, has improved operating efficiency.
