Abstract
The utility model relates to a testing apparatus for the bore pressure of guns used for testing the pressure in the bore. A main body is formed by that the center is provided with an elongate column-shaped cavity metal sleeve pipe, and one end of the sleeve pipe is provided with a pressure sensor which has the same direction with an axis, and a measuring conducting wire is connected with the outer part through the cavity of the sleeve pipe center. The utility model can be used for measuring the air pressure of the powder of any point in the bore without holes which are arranged on the wall surface of the guns, and simultaneously the radial direction in the bore and the axial pressure distributing rule can be measured. The utility model has the advantages of simple measurement, test expense saving, low manufacture cost, strong universality and high accuracy.
Description
The utility model relates to a kind of pressure tester, particularly a kind of cannon chamber pressuring test device of measuring cannon when emission breech pressure.
The pressure distribution and the pressure oscillation of measuring the interior high compact powder grain bed of thorax in the artillery shooting process are the main method that detects the shooting security of cannon ammunition system, also are indispensable means in the interior Ballistics Research.At present, the method for measurement cannon breech pressure time graph has following two kinds of methods:
(1) perforate on barrel screws in pressure sensor.
This method can only obtain the powder pressure near barrel wall place, and in today of large caliber gun extensive use, the roasting and boiling as two means of processing crude drugs gas pressure information that only obtains the wall place is far from being enough.In the coyote hole radially the fluctuation of pressure law and radial pressure influence the main cause of artillery shooting safety often, rupture, come off as the projectile tail wing etc.Simultaneously, because will perforate on the cannon wall, therefore, this method can only be used on the ballistic mortar of special use.
(2) in cannon medicine bed, put into the memory type pressure sensor.
This method is the exploration project of the enforcement period of the seventh five-year plan of Huabei Polytechnical College, and purpose is the test problem that solves the cannon breech pressure, but this method is difficult to promote the use of at present.Main cause has following 3 points: (1) cost height, price is expensive.Because memory chip, its single cost price units up to ten thousand are housed in sensor.And reusable probability is quite low.(2) data are inaccurate, and therefore poor reliability because the motion of powder gases in the thorax makes the memory type sensor be subjected to displacement, is difficult to illustrate that institute's measuring pressure is the force value on which point in thorax.Simultaneously, because the influence that motional inertia moves to the manograph piston, institute's measuring pressure exists than mistake with the force value of reality.(3) use inconvenience.Can only on the reader of special use, data could be read behind this memory type sensor test, therefore, influence the time of quick acquisition institute measurement information, bring very big inconvenience to the user.
The purpose of this utility model be to provide medicine bed arbitrfary point in a kind of energy measurement thorax radially, axial pressure time curve, easy and simple to handle, testing cost is low, not the cannon breech pressure testing arrangement of perforate on the cannon wall.
Realize that the purpose of this utility model technical solution is: a kind of cannon chamber pressuring test device, it is characterized in that it comprises that a center is provided with the long and thin metal sleeve pipe of cylindrical cavity, end at this sleeve pipe, be provided with and casing axis pressure sensor in the same way, in the cavity in sleeve pipe, be provided with an end and be connected, the measurement lead that the other end is connected with outside measuring cell with pressure sensor.
The utility model compared with prior art, its remarkable advantage is: 1, do not need on the cannon wall perforate just can measure powder pressure in the thorax, measure very easyly, can save a large amount of special expenses of producing ballistic mortars; 2, can carry out the radial and axial distribution measuring of cannon breech pressure accurately and reliably.3, cost of manufacture is low, and is easy to use, highly versatile.
Fig. 1 is the structural representation that contains the cannon gun pressure measurement mechanism of evolute pressure sensor
Fig. 2 is the structural representation of setting up with the cannon chamber pressuring test device that the radial pressure sensor is arranged.
Fig. 3 is the structural representation that is provided with the cannon chamber pressuring test device of internal pressure sensor.
Fig. 4 is the state diagram of the utility model when being applied to the cannon gun pressure and measuring.
Below in conjunction with accompanying drawing the present invention is described in further detail.
Cannon gun pressure measurement mechanism of the present utility model is applied to high gun pressure 57mm smooth bore big gun and measures.The sleeve pipe of gun pressure testing arrangement (1) is made by steel alloy, and long 157.5mm, diameter of phi 18mm, the middle Φ 7mm cylindrical hole that bores, front end is provided with step groove, so that strain pressure transducer (2) to be set, this sensor is threaded with the sleeve pipe outward turning, and the place, composition surface establishes sealing ring (4), and the measurement lead (3) that joins with sensor is connected on the externally measured instrument by the circular hole in the middle of the sleeve pipe.In the rear end of sleeve pipe, be provided with spacing ring (5), stretch into the degree of depth in the cartridge with limiting boot.(10) be the fire in a stove before fuel is added, (11) are cartridge case, and (12) are gunpowder, and (13) are barrel, and (14) are bullet.
Embodiment 2.In conjunction with Fig. 2, Fig. 4, other are with embodiment 1, and difference is at sleeve pipe (1) middle part, and radially a pressure sensor (6) is set, its measure lead also by the circular hole edge joint in the sleeve pipe to externally measured instrument.Like this, just realized to survey the axial gun pressure regularity of distribution, can calibrate to pressure law simultaneously again.
Embodiment 3.In conjunction with Fig. 3 Fig. 4; concrete structure is formed with embodiment 1; institute's difference is that the forefront pressure sensor is arranged to internal; being about to pressure sensor (2) is arranged in the joint (7) that shields; and then outward turning is bolted in the front end of sleeve pipe (1), can play the purpose of protection sensor like this.Place, composition surface, pressure sensor two ends is provided with the close ring (8,9) for the treatment of
The utility model can be provided with pressure sensor radially at the middle part of sleeve pipe, is used to measure radial pressure.
