Shown in as shown in Figure 1, Figure 3 and Figure 4, stringer shell provided in an embodiment of the present invention, including shell 1 and stringer 2, shell 1
For rotary type, including covering 11 and it is located at 11 both ends of covering and the integrally formed end frame 12 of covering 11, axis of the stringer 2 along shell 1
It is connect to direction with the inner wall of shell 1.
Stringer shell of the present invention is rotary structure, and frame and covering is held to be integral structure, and no prominent structure can pass through vehicle
System completes the process, and shortens the process-cycle, greatly improves processing efficiency, and upper and lower end frame portion position is designed according to connection size, end
Frame and covering position can be completed the process by vehicle system using seamlessly transitting, greatly improve processing efficiency, reduced stress and concentrated.
Stringer main function is to provide axial support, meets shell bearing capacity, stringer is bonded with the inner wall of shell, allows load mistake
It crosses onto stringer, is not required to specially compared to traditional end frame-skin-stringer structure and grid ribs shell structure, stringer shell of the invention
It is of less demanding to process equipment with riveting type frame, it is not high to the operation level requirement of worker, assembly difficulty and intensity are reduced,
Effectively raise assembly efficiency.Case weight is low, also can effectively reduce body structure weight, improves missile performance.Shell
Geometric tolerance grade is high, significantly improves shell connection size, guarantees the aerodynamic configuration of guided missile.Shell appearance is good, spells without obvious
Seam is reduced because of event occurrence rate of doing over again caused by open defect.
Specifically, stringer 2 and the rivet bottom outlet of shell 1 pass through countersunk head riveting as shown in Fig. 2, shell 1 is equipped with rivet bottom outlet
3 connection of nail.Stringer is bonded with inner walls, and stringer and shell are assembled using rivet interlacement, is not necessarily to special riveting type frame.Stringer with
Shell using 3 sunk head rivet of Φ riveting be assembled together, by lathe on shell by rivet bottom outlet after processing is completed, operator
Member can rivet stringer and shell, greatly reduce the manipulation strength and difficulty of personnel, effectively raise assembly efficiency
With riveting efficiency, assembly intensity and difficulty are reduced.
Wherein, sunk head rivet 3 is riveted from shell 1 to stringer 2, and the countersunk head of sunk head rivet 3 is located at the surface outside shell 1
Lower than the outer wall of shell 1.The pier nose of sunk head rivet inside housings, countersunk head on housing exterior walls and slightly below housing exterior walls
0.1mm~0.3mm guarantees housing exterior walls smoothly without bump.
Further, as shown in figure 5, stringer 2 is T font, including integrally formed wing plate 21 and vertical plate 22, on wing plate 21
Equipped with the through-hole 210 cooperated with rivet bottom outlet, the two sides of vertical plate 22 are equipped with through-hole 210, and wing plate 21 and shell 1 pass through countersunk head riveting
3 connection of nail.Through-hole 210 is uniformly distributed along the length direction of stringer 2, and the through-hole 210 of 22 two sides of vertical plate corresponds.Stringer is cut
Face is T font structure, processes 3 through-hole of Φ in the two sides of the wing plate of stringer, spacing is in 30mm~50mm.
Stringer is positioned with shell as requested, drills 3 rivet bottom outlet of Φ on shell by 3 through-hole of Φ of stringer, and
The outer wall rivet bottom outlet position of shell drills 120 ° of counterbores, and counterbore size is determined by sunk head rivet, using anti-riveting technique by riveting
Nail heading is produced, and is fixed stringer with shell, is successively riveted all stringers.
Wherein, the both ends of stringer 2 are the bending segment 23 to 1 inner inclination of shell, with real in stringer 2 and 11 transition position of covering
Now it is bonded with shell 1.More stringers are circumferentially arranged on the inner wall of the housing, and stringer main function is provides axial branch to shell
Support effect, meets shell bearing capacity.Stringer is formed using aluminum profile panel beating, is fitted closely with inner walls, stringer
Both ends are machined with dog-ear, are bonded it with the transition portion of neighbouring covering with the upper and lower side frame of shell.
In addition, as shown in Fig. 2, end frame 12 is equipped with plate nut 4 on the interface that it is used to that two shells 1 to be made to dock.
Plate nut 4 is riveted by rivet and end frame 12.Plate nut is disposed on the frame of end, plate nut and end frame use 3 countersunk head of Φ
Rivet assembly, is connected and fixed shell with adjacent section shell.Plate nut passes through the through-hole at the frame of shell upper end
Positioning, is fixed plate nut and shell by anti-riveting technique using 3 rivet of Φ.
Stringer shell of the invention is mainly used for the structure of the shells sections such as instrument room shell, attitude control cabin shell, comprehensive for installing
Hop controller, posture control system, the instruments such as inertia combination.Inner walls can install instruments bracket and electric connector bracket, make shell
Body has specific function, and inner walls and outer wall are without bump.The diameter of inventive shell can be 1000mm~1600mm, high
Degree can be 600mm~1200mm, and the thickness of covering can be 2mm~3mm, guarantee that shell dimension control is being conducive to manufacture and carry
Ability reaches in the range of job requirement.Inventive shell can arrange 16~20 stringers, root according to the size of bearing capacity
Determine that the present embodiment circumferentially arranges 16 stringers on shell according to the bearing capacity of shell.
In conclusion stringer shell of the present invention is rotary structure, frame and covering is held to be integral structure, no prominent knot
