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, and in particular to a kind of stagewise barrel attachment structure, it is used for cannon
Connection between two sections of barrels.
Background technology
A kind of known stagewise barrel attachment structure is as shown in Figure 1：Leading portion barrel 1 is reserved convex with the junction of back segment barrel 2
Platform, then be attached by ring flange 4, using a circle bolt 5 by two sections of barrels connection fastenings, while ensure by two sections of barrels it
Between sealing ring 3 compress held one's breath.
With reference to Fig. 1 as can be seen that can have enough precompressions effectively to be held one's breath for guarantee sealing ring 3, two sections of barrels
End face between necessarily have gap, during shooting powder gases enter end face between gap can produce larger axial compressive force.
Secondly, shoot the axial force for producing separately to bear by a circle bolt 5, stress is bad.
The content of the invention
(1) technical problem to be solved
The technical problem to be solved in the present invention is：How a kind of attachment structure between stagewise barrel is provided.
(2) technical scheme
To solve above-mentioned technical problem, the present invention provides a kind of stagewise barrel attachment structure, and it includes：Sealing ring 3, spiral shell
Ring 4, holding screw 5；
The section of the sealing ring 3 is triangle, is sheathed at leading portion barrel 1, the connecting end surface of back segment barrel 2, its triangle
The one cone angle alignment connecting portion of structure, two conical surfaces of the cone angle are adjacent to leading portion barrel 1, the connecting end surface of back segment barrel 2, and this one
Cone angle opposite direction is corresponding facing to outside；
The concrete assemble sequence of the attachment structure is as follows：
Step 1：Volution 4 is inserted in from the left end of leading portion barrel 1, the lap of leading portion barrel 1 and back segment barrel 2 is arranged at
Place；
Step 2：Leading portion barrel 1, back segment barrel 2 and sealing ring 3 are carried out into centering；
Step 3：Volution 4 and the screw thread of sealing ring 3 are tightened；After the completion of ensure the end face patch of leading portion barrel 1 and back segment barrel 2
Tightly, the conical surface that 3 two conical surfaces of sealing ring are engaged with two sections of barrels in front and back has certain precompression；
Step 4：Volution 4 and the junction anti-rotation of back segment barrel 2 are hammered into holding screw 5, and is called the roll in the morning in the upper end of holding screw 5
It is locking；
So far, the connection between two sections of barrels is fully completed.
(3) beneficial effect
The present invention provides a kind of stagewise barrel attachment structure, is attached by volution and nut, the use of section is three
Angular sealing ring is held one's breath, and marks closely anti-rotation using holding screw in addition.Due to sealing ring be located at barrel inner side, during transmitting
Under gun pressure effect, sealing ring is expanded outwardly, and conical surface laminating is more preferable, seals more reliable；Simultaneously powder gases will not enter two sections of bodies
The gap of end surfaces, therefore inertia force of coupling part when only needing to bear back seat, it is not necessary to bear gun pressure, axially loaded is little；
Used as an entirety, more preferably, attachment structure is compact for stress for volution connection.
Compared with prior art, the present invention possesses following beneficial effect：
1st, stagewise barrel attachment structure is made up of leading portion barrel, back segment barrel, sealing ring, volution, holding screw.
2nd, held one's breath by sealing ring, sealing ring coordinates the conical surface to have certain precompression with front and rear sections barrel.
3rd, the connection fastening of two sections of barrels realizes that attachment structure is compact by volution.
4th, four road air slots are arranged in leading portion barrel end surface symmetric, steam vent is reserved on back segment barrel and connection ring
Description of the drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is the stagewise barrel attachment structure schematic diagram of the present invention.
Fig. 3 is the structural representation of air slot.
Specific embodiment
To make the purpose of the present invention, content and advantage clearer, with reference to the accompanying drawings and examples, to the present invention's
Specific embodiment is described in further detail.
To solve problem of the prior art, the present invention provides a kind of stagewise barrel attachment structure, and it includes：Sealing ring 3,
Volution 4, holding screw 5；
The section of the sealing ring 3 is triangle, is sheathed at leading portion barrel 1, the connecting end surface of back segment barrel 2, its triangle
The one cone angle alignment connecting portion of structure, two conical surfaces of the cone angle are adjacent to leading portion barrel 1, the connecting end surface of back segment barrel 2, and this one
Cone angle opposite direction is corresponding facing to outside；
The concrete assemble sequence of the attachment structure is as follows：
Step 1：Volution 4 is inserted in from the left end of leading portion barrel 1, the lap of leading portion barrel 1 and back segment barrel 2 is arranged at
Place；
Step 2：Leading portion barrel 1, back segment barrel 2 and sealing ring 3 are carried out into centering；
Step 3：Volution 4 and the screw thread of sealing ring 3 are tightened；After the completion of ensure the end face patch of leading portion barrel 1 and back segment barrel 2
Tightly, the conical surface that 3 two conical surfaces of sealing ring are engaged with two sections of barrels in front and back has certain precompression；
Step 4：Volution 4 and the junction anti-rotation of back segment barrel 2 are hammered into holding screw 5, and is called the roll in the morning in the upper end of holding screw 5
It is locking；
So far, the connection between two sections of barrels is fully completed.
Wherein, the end surface symmetric in leading portion barrel 1 arranges four road air slots, as shown in Figure 3；Air slot to be arranged at it is corresponding
The steam vent 6 of position coordinates for powder gases to be derived into barrel after the unexpected failure of sealing ring 3, prevents because breech pressure is excessive right
Barrel or coupling part produce injury.
To sum up, the present invention adopts brand-new attachment structure, with advantages below：
1st, due to sealing ring be located at barrel inner side, during shooting in the presence of gun pressure, sealing ring is expanded outwardly, with barrel it
Between paste tighter and tighter, seal it is more reliable；
2nd, volution is connected as overall stress, and uniform force, attachment structure is compact；
3rd, four road air slots are arranged in leading portion barrel end surface symmetric, steam vent is reserved on back segment barrel and connection ring, used
Powder gases are derived into barrel after sealing ring surprisingly fails, can effectively be prevented because breech pressure is excessive to barrel or connecting portion
Divide and produce injury.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, on the premise of without departing from the technology of the present invention principle, some improvement and deformation can also be made, these improve and deform
