Abstract
The invention belongs to the technical field of gun design and in particular relates to a segmented type barrel connecting structure for connecting two segmentations of barrels of a gun. In the structure, connection is carried out through whorls and nuts; obturation is carried out by using a sealing ring with the cross section to be triangular; and in addition, set screws are adopted to prevent rotation. According to the structure disclosed by the invention, as being arranged on the inner sides of the barrels, the sealing ring expands outwards under the action of gun pressure during shooting, the conical surfaces are better in cling, and sealing is more reliable; meanwhile, gunpowder gas cannot enter an interval between the end surfaces of the two segmentations of the barrels, so that the connecting part only needs to bear the inertia force of a back seat without bearing the gun pressure, and the axial stress is weak; and as the whorls are connected to form a whole body, the stress state is better, and the connecting structure is compact.
Description
Technical field
The invention belongs to gun test technical field, be specifically related to a kind of segmented barrel syndeton, it is for the connection between cannon two sections of barrels.
Background technology
Known a kind of segmented barrel syndeton is as shown in Figure 1: boss is reserved in leading portion barrel 1 and back segment barrel 2 junction, connected by ring flange 4 again, use a circle bolt 5 to connect fastening by two sections of barrels, the sealing ring 3 between simultaneously ensureing two sections of barrels compresses holds one's breath.
Composition graphs 1 can be found out, for ensureing that sealing ring 3 can have enough precompressions effectively to hold one's breath, must have gap between the end face of two sections of barrels, the gap that during shooting, powder gases enters between end face can produce larger axial compressive force.
Secondly, the axial force that shooting produces separately is born by a circle bolt 5, and stress is bad.
Summary of the invention
(1) technical problem that will solve
The technical problem to be solved in the present invention is: how to provide the syndeton between a kind of segmented barrel.
(2) technical scheme
For solving the problems of the technologies described above, the invention provides a kind of segmented barrel syndeton, it comprises: sealing ring 3, volution 4, holding screw 5;
Described sealing ring 3 cross section is triangle, be sheathed on leading portion barrel 1, back segment barrel 2 connecting end surface place, one cone angle of its triangular structure aims at connecting portion, and two conical surfaces of this cone angle are adjacent to leading portion barrel 1, back segment barrel 2 connecting end surface, and this cone angle is corresponding to outside in the other direction;
The concrete assemble sequence of this syndeton is as follows:
Step 1: be inserted in from leading portion barrel 1 left end by volution 4, is arranged at the office, overlapping portion of leading portion barrel 1 and back segment barrel 2;
Step 2: leading portion barrel 1, back segment barrel 2 and sealing ring 3 is carried out centering;
Step 3: by volution 4 and sealing ring 3 screwed tight; After completing, the end face of guarantee leading portion barrel 1 and back segment barrel 2 is adjacent to, and the conical surface that sealing ring 3 two conical surfaces match with two sections, front and back barrel has certain precompression;
Step 4: hammer into volution 4 and back segment barrel 2 junction anti-rotation with holding screw 5, and call the roll in the morning locking in holding screw 5 upper end;
So far, the connection between two sections of barrels all completes.
(3) beneficial effect
The invention provides a kind of segmented barrel syndeton, be connected with nut by volution, use cross section to be that leg-of-mutton sealing ring is held one's breath, adopt holding screw to mark closely anti-rotation in addition.Because sealing ring is positioned at inside barrel, during transmitting under gun pressure effect, sealing ring expands outwardly, and conical surface laminating is better, seals more reliable; Powder gases can not enter the gap of two sections of barrel end faces simultaneously, and therefore coupling part only needs inertia force when bearing back seat, and do not need to bear gun pressure, axially loaded is little; Volution connects integrally, and stress is better, and syndeton is compact.
Compared with prior art, the present invention possesses following beneficial effect:
1, segmented barrel syndeton is made up of leading portion barrel, back segment barrel, sealing ring, volution, holding screw.
2, held one's breath by sealing ring, sealing ring coordinates the conical surface to have certain precompression with front and rear sections barrel.
3, the connection of two sections of barrels is fastening is realized by volution, and syndeton is compact.
4, four road air slots are arranged at leading portion barrel end surface symmetric, reserved steam vent on back segment barrel and connecting ring
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is segmented barrel syndeton schematic diagram of the present invention.
Fig. 3 is the structural representation of air slot.
Detailed description of the invention
For making object of the present invention, content and advantage clearly, below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.
For solving the problem of prior art, the invention provides a kind of segmented barrel syndeton, it comprises: sealing ring 3, volution 4, holding screw 5;
Described sealing ring 3 cross section is triangle, be sheathed on leading portion barrel 1, back segment barrel 2 connecting end surface place, one cone angle of its triangular structure aims at connecting portion, and two conical surfaces of this cone angle are adjacent to leading portion barrel 1, back segment barrel 2 connecting end surface, and this cone angle is corresponding to outside in the other direction;
The concrete assemble sequence of this syndeton is as follows:
Step 1: be inserted in from leading portion barrel 1 left end by volution 4, is arranged at the office, overlapping portion of leading portion barrel 1 and back segment barrel 2;
Step 2: leading portion barrel 1, back segment barrel 2 and sealing ring 3 is carried out centering;
Step 3: by volution 4 and sealing ring 3 screwed tight; After completing, the end face of guarantee leading portion barrel 1 and back segment barrel 2 is adjacent to, and the conical surface that sealing ring 3 two conical surfaces match with two sections, front and back barrel has certain precompression;
Step 4: hammer into volution 4 and back segment barrel 2 junction anti-rotation with holding screw 5, and call the roll in the morning locking in holding screw 5 upper end;
So far, the connection between two sections of barrels all completes.
Wherein, four road air slots are arranged at the end surface symmetric of leading portion barrel 1, as shown in Figure 3; Air slot coordinate with the steam vent 6 being arranged at relevant position lost efficacy for sealing ring 3 is unexpected after powder gases is derived barrel, prevent from producing barrel or coupling part because breech pressure is excessive injuring.
To sum up, the present invention adopts brand-new syndeton, has the following advantages:
1, because sealing ring is positioned at inside barrel, during shooting under the effect of gun pressure, sealing ring expands outwardly, and pastes tighter and tighter between barrel, seals more reliable;
2, volution connects for overall stressed, uniform force, and syndeton is compact;
3, arrange four road air slots at leading portion barrel end surface symmetric, on back segment barrel and connecting ring, reserved steam vent, by powder gases derived barrel after surprisingly losing efficacy for sealing ring, can effectively prevent from producing injury because breech pressure is excessive to barrel or coupling part.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
