Description
Technical field
The utility model separation of the projectile seat device, belongs to bullet and tests the speed field.
Background technology
Gas big gun is the one kind for directly using the gas under compressive state to promote bullet to accelerate in bore as former driving force
Equipment, is mainly used in the research of the aspects such as material fundamental characteristics and explosion physics.Bullet support, is as the development of ammunition technology is produced
Raw, in order to improve the armor-penetrating ability of bullet, generally use large caliber gun to launch Small cartridge, i.e. calibre projectiles, but to make
Calibre projectiles are adapted to heavy caliber light-gas gun it is necessary to use bullet support.Bullet support belongs to " passiveness " quality of bullet, so bullet support quality will
It is as light as possible, while when bullet flies away from bore, it is desirable to which bullet support can be separated promptly with bullet, reach interference of the bullet support to bullet
To minimum, a kind of separation of the projectile seat device is at this moment needed.
At present, although existing pneumatic separation bullet support can save attachment device to separation of the projectile seat, and the outer bullet of bullet can be improved
Path needed for road performance but separation is (more than 10 meters) more long, is not suitable for small-sized target cabin.It is general that small-sized target cabin carries out separation of the projectile seat
Using forcing to separate, most common bullet support and separation of the projectile seat device are cylindrical bullet support and orifice type separation of the projectile seat device.Cylinder
Although shape bullet support and orifice type separator simple structure, it is easy to process, there is two shortcomings：1. quality shared by bullet support is relatively
Greatly, can reduce bullet goes out thorax speed；2. bullet support can change original path after being contacted with separation of the projectile seat device, exist certain
It is dangerous.And the bellmouth blocking apparatus that China Engineering Physics Research Institute uses can influence the stabilization of bullet trajectory to a certain extent
Property.
Utility model content
Goal of the invention：In order to overcome the deficiencies in the prior art, the utility model provides a kind of separation of the projectile seat device,
Bullet support is lightweight, and bullet kinetic energy rejection is small, and bullet enters in separation block, the good stability of bullet.
Technical scheme：In order to solve the above technical problems, separation of the projectile seat device of the present utility model, including bullet support and separation
Block, the front end of the bullet support is provided with blind hole, and bullet is clamped with blind hole, and the rear end of bullet support is provided with cylindrical groove, outside bullet support
Footpath maximum 0.1~0.2mm smaller than gun tube internal diameter, through hole is provided with the separation block, and the through hole includes three sections, and first paragraph is cone
Shape mouthful, conical opening is used with the pairing of bullet support, and interlude is correction section, and the inlet diameter of interlude is the 1.5~1.6 of bullet diameters
Times, the outlet diameter 0.1~0.2mm bigger than bullet diameters of interlude, the 3rd section is cylindrical section.
Preferably, the correction section is 3~4 times of bullet length, the 3rd section of length for 5 times of bullet length and with
On.
Preferably, the separation block is covered with protective case, protective case one end is enclosed within gun tube.
Preferably, the protective case is telescopic protection set.
Beneficial effect：Separation of the projectile seat device of the present utility model, bullet support is lightweight, and bullet kinetic energy rejection is small, and bullet enters
Separate in block, due to separating the through hole of block using three sections of designs, the flight path of bullet is corrected, the stability of bullet
It is good.

Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, separation of the projectile seat device of the present utility model, including bullet support 3 and separation block 5, the bullet support 3
Front end be provided with blind hole, bullet 4 is clamped with blind hole, the rear end of bullet support 3 is provided with cylindrical groove, the largest outside diameter value of bullet support 3
Than the small 0.1~0.2mm of the internal diameter of gun tube 1, through hole is provided with the separation block 5, the through hole includes three sections, and first paragraph is conical opening,
Conical opening is used with the pairing of bullet support 3, and interlude is correction section, and the inlet diameter of interlude is 1.5~1.6 times of the diameter of bullet 4,
Than the big 0.1~0.2mm of the diameter of bullet 4, the 3rd section is cylindrical section to the outlet diameter of interlude, and the correction section is the length of bullet 4
3~4 times, the 3rd section of length for 5 times of the length of bullet 4 and more than, the separation block 5 is covered with protective case 2, protective case 2
One end is enclosed within gun tube 1, and the protective case 2 is telescopic protection set 2.
The utility model when in use, is separated block and is arranged in target cabin by screw 7, to be separated and be provided with guarantor between block and target cabin
Pad ring 6.Target plate support 10 is installed in target cabin, target plate support is arranged in target cabin 8 by screw 9, is led on target plate support
Cross nut 11 and screw 12 is provided with target plate 13.Bullet 4 and bullet support 3 are added by gun tube 1 together using compressed gas during transmitting
Speed to the required speed for using takes off thorax, and separation block 5 is run into after bullet 4 and one segment distance of flight of bullet support 3 after de- thorax, is separating block
In 5, bullet 4 is separated from bullet support 3, into through hole, is injected on target plate 13.
The above is only preferred embodiment of the present utility model, it should be pointed out that：For the common skill of the art
