Description

  The present invention relates to an operation checking device for an automatic loading gun configured to simulate the extraction of a cartridge case and the kicking and the feeding and loading of ammunition by an operating mechanism that is operated by gas pressure at the time of bullet firing. is there.

  For example, as described in Patent Document 1 and Patent Document 2, the automatic loading type firearm is operated by introducing gas at the time of bullet firing from the barrel into the cylinder. The slide bottom is retracted by retreating the gas piston or the actuating rod, and the slide bottom retreats to the predetermined position while pressing the back seat spring, and then advances or recovers by the spring force of the back seat spring. Sit down. By the rearward seating of the slide bottom portion, the barrel of the slide bottom portion is kicked out and loaded with ammunition. In such an automatic loading type firearm, it is necessary to reliably carry out the extraction of the cartridge case, the kicking out and the loading of the ammunition. In particular, firearms with a continuous fire function, such as automatic firearms that are self-loading guns, cannot be fired unless the ammunition is loaded and the cartridge barrels and kicks out reliably. Not. For this reason, a confirmation test is carried out to confirm whether the cartridge drawer and kick-out and ammunition loading are performed reliably. This confirmation test was carried out by actual shooting.

Japanese Examined Patent Publication No. 4-78918 JP 56-44597 A

Since the confirmation test of cartridge extraction and kicking and loading of ammunition with the conventional automatic loading gun is based on actual bullet shooting, there is a problem that it is necessary to perform in the shooting range and the place where the verification test is performed is limited, or real bullet shooting Because only authorized persons can use ammunition and ammunition, there was a problem that restricted the examination personnel. In addition, because it shoots live bullets, the residue (non-combustible powder (non-burning powder), etc.) is diffused and high-temperature cartridges are kicked out. There is a problem that can not be confirmed near the type gun, there is a problem that can only be confirmed with images such as video, and in addition, in order to fire live bullets with self-loading type guns, the gun is fixed so that it can withstand the shooting reaction Therefore, there is a problem that a large-scale equipment such as a sturdy and heavy mount is required. In addition, since the confirmation test is performed by actual bullet shooting, it costs money to consume ammunition each time it is shot, and the size and shape of the gun parts are changed, and the speed of retreating and advancing the bottom is changed. There was a problem that the test could not be easily performed by changing the test conditions, or the test preparation was required due to the schedule of the test and the installation of equipment.
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems, and to provide an operation check device for an automatic loading gun that can check the loading of ammunition, the barrel of the cartridge case, and the kicking without performing actual shooting. Objective.

  The present invention provides a holding member capable of holding a self-loading gun which is configured to perform extraction and loading of ammunition by means of a slide bottom of an operating mechanism operated by gas pressure for firing a bullet, and the slide. An engaging member that engages with the bottom portion and a reciprocating drive device that reciprocates the engaging member in the front-rear direction. The slide bottom portion is reciprocated by the reciprocating drive device to It is characterized by simulating from bullet feeding to loading.

A speed regulator is provided that can adjust the reciprocating speed of the slide bottom part by the reciprocating drive device so as to be close to the moving speed of the slide bottom part that is operated by the gas pressure of the fired bullet.
Further, the engaging member is characterized in that the sliding bottom portion can be engaged with a hook that can be manually reciprocated.
The reciprocating drive device is a pneumatic cylinder provided with a piston. The pneumatic cylinder is connected to a pneumatic pressure source via a flow rate adjusting valve as a speed regulator, an engagement member is provided on the piston, and It is characterized in that the slide bottom portion is reciprocated by movement.

The present invention provides a holding member capable of holding a self-loading gun which is configured to perform extraction and loading of ammunition by means of a slide bottom of an operating mechanism operated by gas pressure for firing a bullet, and the slide. An engaging member that engages with the bottom portion and a reciprocating drive device that reciprocates the engaging member in the front-rear direction. The slide bottom portion is reciprocated by the reciprocating drive device to Since the process from feeding to loading is simulated, it is possible to easily check the cartridge barrel and the kicking and loading of ammunition without performing actual shooting.
Accordingly, it is not necessary for personnel authorized to shoot real ammunition and use of ammunition to perform a confirmation test at the launch site, and it is preferable that the place and the test personnel for performing the confirmation test are not restricted. The test place and test personnel are not constrained, so the test preparation is not required, and even if the dimensions and shape of each part of the self-loading gun are changed, the effect of changing the dimensions and shape can be confirmed immediately. is there. Further, compared to the case where actual bullet shooting is performed, no residue scatters and the like is safer, and it is possible to confirm the extraction of the cartridge case, the kicking out, and the loading of the ammunition near the automatic loading gun. In addition, since the configuration of the operation check device is simple, it is compact. In addition, since the slide check bottom of the automatic loading gun is reciprocated by the operation confirmation device, no large reaction is generated, and a large-sized equipment such as a sturdy and heavy gantry is not required for the actual shooting. In addition, since simulated ammunition and shells are used without using actual ammunition, simulated ammunition and shells can be used repeatedly, which has the effect of reducing test costs.

  Since the reciprocating speed of the slide bottom part by the reciprocating drive device is equipped with a speed regulator that can be adjusted to approximate the moving speed of the slide bottom part that is activated by the gas pressure of the fired bullet, With the reciprocating speed of the slide bottom portion approximated when the slide bottom portion is moved, it is possible to confirm the extraction of the cartridge case, kicking out and loading of ammunition. In addition, the reciprocating speed of the slide bottom of the various self-loading guns used in the verification test is approximated to the sliding bottom movement speed due to the gas pressure at the time of bullet firing, that is, the verification test corresponding to the self-loading gun. Since the moving speed of the engagement member by the reciprocating drive device at the time can be changed, the moving speed of the slide bottom can be changed by changing the moving speed of the engaging member, and easily under various test conditions There is an advantage that can be confirmed.

  The engaging member can be easily engaged with a self-loading gun because the sliding bottom portion can be manually engaged with a rod that can be reciprocally moved. Confirmation tests can be performed for various small firearms.

  The reciprocating drive device is a pneumatic cylinder provided with a piston. The pneumatic cylinder is connected to a pneumatic pressure source via a flow rate adjusting valve as a speed regulator, an engagement member is provided on the piston, and Since the slide bottom is reciprocated by the movement, a confirmation test can be performed anywhere if there is an air pressure source, and the pneumatic cylinder is operated by the air pressure, so that the piston can be moved instantaneously at high speed.

  The reciprocating drive device 4 is a well-known pneumatic cylinder, for example, substantially the same as the rodless cylinder disclosed in Japanese Patent Laid-Open No. 2000-249108. Here, an outline of the rodless cylinder 4 will be described. The cylinder tube 10 has a cylinder hole over the entire length in the longitudinal direction, and a slit is formed over the entire length in the longitudinal direction. Both ends of the cylinder hole are closed by the end cap 11 and are divided into front and rear cylinder chambers 13 and 14 by a piston 12 slidably fitted. The piston 12 is integrally provided with a piston mount 16 as a moving body that passes through the slit and is located outside the cylinder tube 10, and a seal band 15 that closes the slit passes through the piston 12. By supplying and discharging the pressurized fluid to the front and rear cylinder chambers 13 and 14, the piston band 16 is reciprocated integrally with the piston 12 while the seal band 15 closes the slit except for the portion passing through the piston 12. It has become. The engagement member 5 is detachably screwed to the piston mount 16 with a bolt. The engaging member 5 is adapted to engage with the slide free bottom portion 18 of the automatic rifle 1. The reciprocating drive device 4 may be a linear motor, an actuator that reciprocates with a motor and a feed screw, a mechanism that converts rotation of the motor into linear motion, or the like.

  The automatic rifle 1 has an operating mechanism (not shown) that operates by gas pressure for firing a bullet. The operating mechanism is provided with a slide bottom 18 and a return spring 19 and the like. The automatic rifle 1 is loaded with ammunition when the slide bottom portion 18 is reared by the gas pressure to kick out the cartridge 20 and the slide bottom portion 18 is retracted by the return spring 19. It is like that. The slide bottom portion 18 is provided with a collar 21 that can manually move the slide bottom section 18 in a reciprocating manner. The collar 21 is engaged with the automatic rifle 1 when the automatic rifle 1 is attached to the support base 3. It is engaged with an engaging recess 22 formed in the member 5.

  The holding member 23 provided on the support 3 can hold the automatic rifle 1. The holding member 23 includes left and right fixing means 24 for fixing the automatic rifle 1 from the left and right, and upper and lower fixing means 25 and 26 for fixing from the upper and lower sides. The holding member 23 is provided on the support base 3 so as to be replaceable depending on the type of gun for which the confirmation test is performed. The left-right fixing means 24 is configured symmetrically (only one is shown in FIG. 2), and an operating member 29 for screwing the screw shaft 28 to the support plate 27 and rotating the screw shaft 28 at one end. A clamping member 30 for sandwiching the automatic rifle 1 is attached to the other end. The vertical fixing means 25 is a so-called toggle clamp. For example, the clamp lever 32 swings in the vertical direction by operating the operation lever 31 as disclosed in Japanese Patent Application Laid-Open No. 10-249741. The automatic rifle 1 is clamped and unclamped by the clamp lever 32. The vertical fixing means 26 is a fixing screw that is inserted into the support plate 8 and screwed into the automatic rifle 1.

  Next, the operating device 6 will be described. As shown in FIG. 3, the operating device 6 is connected to the pneumatic pressure source 33, and supplies the compressed air from the pneumatic pressure source 33 to one of the forward supply / discharge port 34 or the reverse supply / discharge port 35 of the rodless cylinder 4. Open the other to the atmosphere. As shown in FIG. 3, the filter 36 is connected to the compressed air source 33, and a regulator 37 that reduces the pressurized air to a predetermined pressure is connected to the filter 36. The regulator 37 is connected to a lubricator 38 for supplying mist-like oil. The lubricator 38 is connected in parallel to the forward push button means 39, the reverse push button means 40, and the switching valve 41. A flow path 42 connected to the forward supply / discharge port 34 of the rodless cylinder 4 and a flow path 43 connected to the reverse supply / discharge port 35 of the rodless cylinder 4 are connected to the switching valve 41. A forward hand valve 44 is connected in the middle of the flow path 42, and a backward hand valve 45 is connected in the middle of the flow path 43.

  The forward push button means 39 includes a push button operation type switching valve 46 and a forward push button 47, and the switching valve 46 is connected to a pilot chamber 48 of the switching valve 41. The reverse push button means 40 includes a push button operation type switching valve 49 and a reverse push button 50, and the switching valve 49 is connected to a pilot chamber 51 of the switching valve 41. When the forward push button 47 is pressed, the pilot chamber 48 of the switching valve 41 communicates with the air pressure source 33, and pilot pressure is supplied to the pilot chamber 48, so that the switching valve 41 is moved to one forward switching position A shown in FIG. Is switched. When the switching valve 41 is switched to the forward switching position A, the compressed air from the pneumatic pressure source 33 is supplied to the forward supply / discharge port 34 of the rodless cylinder 4 and the reverse supply / discharge port 35 is opened to the atmosphere and exhausted. The piston 12 moves forward. When the reverse push button 50 is pressed, the pilot chamber 51 of the switching valve 41 and the air pressure source 33 communicate with each other, the pilot pressure is supplied to the pilot chamber 51 and the switching valve 41 is switched to the other reverse switching position B. It is done. When the switching valve 41 is switched to the reverse switching position B, the compressed air from the pneumatic pressure source 33 is supplied to the reverse supply / discharge port 35 of the rodless cylinder 4 and the forward supply / discharge port 34 is opened to the atmosphere and exhausted. The piston 12 moves backward.

  The forward-side hand valve 44 and the backward-side hand valve 45 are three-way valves, and normally connect the switching valve 41 and the forward supply / discharge port 34 and the reverse supply / discharge port 35 of the rodless cylinder 4, respectively. When the forward hand valve 44 and the backward hand valve 45 are switched, the forward supply / discharge port 34 and the reverse supply / discharge port 35 are exhausted, and the supply of compressed air from the air pressure source 33 is stopped. Between the operating device 6 and the forward supply / discharge port 34 of the rodless cylinder 4 and between the operating device 6 and the reverse supply / discharge port 35 of the rodless cylinder 4, a flow rate adjusting valve 52 as a speed regulator, respectively. , 53 are connected. By operating these flow rate adjusting valves 52 and 53, the moving speed of the piston 12 in the front-rear direction can be adjusted, whereby the reciprocating speed of the slide bottom portion 18 of the automatic rifle 1 can be adjusted. ing.

  Next, a confirmation test of the automatic rifle 1 will be described. The automatic rifle 1 is fixed to the support 3 by the left and right fixing means 24 and the vertical fixing means 25 and 26, and the engaging member 5 is engaged with the collar 21 of the automatic rifle 1. Further, the moving speed of the piston 12 of the rodless cylinder 4 is approximate to the moving speed of the slide bottom 18 that is operated by the gas pressure of the bullet when the automatic rifle 1 is fired, or a desired moving speed. The flow rate adjustment valves 52 and 53 are adjusted so that First, a case will be described in which a confirmation test is conducted on the extraction of the cartridge case 20 and the kicking-out of the case 20 from the chamber 54. The reversing push button 50 is pressed to set the switching valve 41 to the other reversing switching position B, and the slide bottom portion 18 is retreated together with the piston 12.

  With the slide bottom 18 retracted, only the cartridge case 20 is manually loaded into the chamber 54. The reason why only the cartridge case 20 is loaded is to make it similar to the actual barrel and kicking out of the cartridge case 20, and when ammunition is used, bullets are attached and the length and weight are different. This is because the movement to be kicked out of the extraction cylinder and the movement of the cartridge case 20 to be kicked out are different. After loading the cartridge case 20, the forward push button 47 is pushed, the switching valve 41 is set to the forward switching position A, the compressed air is supplied to the forward supply / discharge port 34, the backward supply / discharge port 35 is exhausted, and the piston 12 slides together. Advance the bottom 18.

  In this state, when the backward push button 50 is pressed, the switching valve 41 is switched from the forward switching position A in FIG. 3 to the backward switching position B, and the forward supply / exhaust port 34 of the rodless cylinder 4 is exhausted. The compressed air is supplied to the supply / discharge port 35, and the slide free bottom portion 18 moves backward together with the piston 12. As a result, the slide bottom portion 18 draws the cartridge case 20 from the drug chamber 54, and the cartridge case 20 is kicked out from the automatic rifle 1. Since the compressed air is supplied to the rodless cylinder 4 from the backward supply / discharge port 35, the piston 12 is positioned on the forward supply / discharge port 34 side of the rodless cylinder 4. Maintain the state. In the case of a test for confirming the extraction and kicking out of the cartridge case 20 again, only the cartridge case 20 is manually loaded into the chamber 54 in the same manner as described above, and the push buttons 47 and 50 are pressed as described above. Conduct a confirmation test.

  Next, the case where a loading test of ammunition is confirmed will be described. The automatic rifle 1 is equipped with a magazine 55 containing a simulated bullet as an ammunition. By pushing the reverse push button 50 and setting the switching valve 41 to the reverse switching position B, the piston 12 is retracted to bring the slide bottom 18 into the reverse state. When the forward push button 47 is pressed, the switching valve 41 is switched from the reverse switching position B to the forward switching position A, and the piston 12 moves forward by the pressurized air supplied to the forward supply / discharge port 34, whereby the slide free bottom 18 Will move forward. As the slide bottom part 18 moves forward, the slide bottom part 18 loads the simulated bullets from the magazine 55 into the chamber 54. By repeating this, the ammunition loading confirmation test is performed.

  When it is desired to replace the internal parts of the automatic rifle to change the gun or change the test conditions in the confirmation test, or to shut off the compressed air from the pneumatic source 33 such as when the test is finished, the forward hand valve 44 and the reverse side valve The side hand valve 45 is switched. As a result, the forward supply / exhaust port 34 and the reverse supply / exhaust port 35 of the rodless cylinder 4 are brought into an exhaust state, and the compressed air does not act on the rodless cylinder 4. In this state, even if the forward push button 47 or the backward push button 50 is operated, the slide free bottom 18 does not move.

  By operating the flow rate adjusting valves 52 and 53 as described above, the forward and backward speeds of the slider free bottom portion 18 can be adjusted, and if the engagement member 5 and the holding member 23 are replaced, various gun types can be handled. Confirmation test can be performed under various test conditions. In addition, without using actual ammunition, the slide bottom 18 is moved forward and backward by the rodless cylinder 4 during the confirmation test, so the location and personnel are not restricted, and the incombustible powder is not scattered, which is safe. The movable state can be directly confirmed near the automatic rifle 1, and a confirmation test can be immediately performed even when the design of the automatic rifle 1 is changed. In addition, since a large reaction does not occur unlike actual bullet shooting, large equipment is not required. Further, the cartridge case 20 and the simulated ammunition can be reused, and the test can be performed at a lower cost than when expensive actual ammunition is used.
