Description

反衝式自動武器循環射擊機構Recoil type automatic weapon circulation shooting mechanism

本發明是關於一種自動武器連續射擊機械結構,特別是一種反衝式自動武器循環射擊機構。The invention relates to a continuous shooting mechanism of an automatic weapon, in particular to a recoil type automatic weapon cyclic shooting mechanism.

習知的一種自動射擊武器例如申請人先前取得之中華民國公告第I585359號「可連續擊發槍管後座式自動武器循環射擊機構」發明專利,其揭示一種使用全威力步槍彈或中間威力步槍彈的高膛壓自動武器的連續射擊機構。請參照圖1,該機構係包括槍身10、槍管組、槍機組、擊針組及復進簧座組等5項主要總成。其中,槍管組包含一槍管11及一槍管套111, 槍機組包含一槍機13、一槍閂14、一槍機簧133及一凸輪銷131,擊針組包含一擊針142及一擊針頂桿132,復進簧座組包含一復進簧座15及一復進簧151。A conventional automatic firing weapon, such as the ROC Announcement No. I585359 "Continuous firing barrel rear seat automatic weapon cyclic shooting mechanism" invention patent previously obtained by the applicant, which discloses the use of full-power rifle cartridges or intermediate-power rifle cartridges The continuous firing mechanism of the high-pressure automatic weapon. Please refer to Figure 1. The mechanism includes five main assemblies: the gun body 10, the barrel unit, the gun unit, the firing needle unit and the recoil spring seat unit. Among them, the barrel set includes a barrel 11 and a barrel sleeve 111, the gun set includes a bolt 13, a bolt 14, a bolt spring 133 and a cam pin 131, and the firing needle set includes a firing pin 142 and One hitting pin plunger 132, the recoil spring seat set includes a recoil spring seat 15 and a recoil spring 151.

該習知機構單次循環運作之步驟為:彈藥擊發時,發射藥產生之瞬間高壓氣體推動彈頭往前,同時推動槍閂14向後,此時槍管組之槍管套111與槍機組之槍閂14呈閉鎖結合狀態,因而兩者一起後座,同時壓縮槍管簧12儲存能量。The steps of the conventional mechanism in a single cycle operation are: when the ammunition is fired, the instant high-pressure gas generated by the propellant pushes the warhead forward, and at the same time pushes the bolt 14 backwards. At this time, the barrel sleeve 111 of the barrel set and the gun of the gun set The latch 14 is in a locked and combined state, so the two are seated together, while compressing the barrel spring 12 to store energy.

槍機13因受到本身質量慣性及復進簧座組支撐力,尚停留於原處,槍機組之槍機簧133因此受到槍管組與槍閂14後座擠壓,一方面承受並消耗槍管11後座力,另一方面儲存能量。The bolt 13 still stays in place due to its mass inertia and the support of the reentry spring seat assembly. The bolt action spring 133 of the gun unit is therefore squeezed by the barrel assembly and the rear seat of the bolt 14, which bears and consumes the gun. The tube 11 recoils, on the other hand, stores energy.

當槍機簧133承受槍管11後座力壓縮到極限時開始回彈,能量釋出便推動槍機13及復進簧座組後退,槍機13後退時,固定於槍機13之凸輪銷131亦向後,在槍閂14之凸輪槽141呈曲線形狀的行程限制下,槍機13帶動槍閂14旋轉並與槍管套111完成分離(開閂),槍管11後退到極限位置後,因槍管簧12的簧力釋放開始復進歸位。槍機13與槍閂14持續拉彈殼向後,當彈殼脫離槍管套111時,退殼挺受到退殼挺簧作用下,將彈殼拋離槍身10,完成退殼及拋殼動作。When the bolt spring 133 is compressed to the limit with the recoil force of the barrel 11, it starts to rebound. The energy released pushes the bolt 13 and the recoil spring seat assembly to retreat. When the bolt 13 retreats, it is fixed to the cam pin of the bolt 13 131 is also backward. Under the curvilinear stroke limit of the cam groove 141 of the breech block 14, the bolt 14 is driven to rotate by the bolt 14 and separated from the barrel cover 111 (unbolt). After the barrel 11 is retracted to the limit position, Due to the release of the spring force of the barrel spring 12, it starts to return to its position. The bolt 13 and the bolt 14 continue to pull the cartridge case backwards. When the cartridge case is separated from the barrel sleeve 111, the ejector is under the action of the ejector spring and throws the cartridge away from the gun body 10 to complete the ejection and ejection actions.

當復進簧座組之復進簧座15後退撞擊至槍身10底部時,完成自動循環之後座到位,此時復進簧151開始回彈釋放能量推動槍機組、擊針組及復進簧座組往前復進,槍閂14的推彈齒會推動次發彈向前進入彈膛內,完成自動循環之推彈及進彈動作,最後槍閂14進入槍管套111內頂住槍管11尾端,槍機13持續推擠槍閂14,受到槍閂14的凸輪槽141行程限制,槍閂14受擠壓旋轉與槍管套111結合,完成自動循環之閉鎖動作。When the recoil spring seat 15 of the recoil spring seat assembly retreats and hits to the bottom of the gun body 10, the seat is in place after the automatic cycle is completed. At this time, the recoil spring 151 begins to rebound and release energy to push the gun unit, firing needle assembly and recoil spring The seat assembly moves forward and backward, and the push teeth of the bolt 14 will push the secondary bullet forward into the chamber to complete the automatic cycle of push and advance actions. Finally, the bolt 14 enters the barrel sleeve 111 to support the gun At the end of the tube 11, the bolt 13 continues to push the breech block 14, limited by the stroke of the cam groove 141 of the breech block 14, the breech block 14 is squeezed and rotated and combined with the barrel sleeve 111 to complete the automatic loop locking action.

此時,擊針組之擊針142因槍閂14旋轉頂端自然突出,且受到與復進簧座15結合之擊針頂桿132頂住,撞擊次發彈藥底火力量足夠而且持續,不受槍機13復進撞擊槍機簧133之回震影響而使撞擊力量中斷,擊發次發彈藥後進入退殼、拋殼、後座、復進、推彈及進彈、閉鎖及擊發之自動武器射擊作動循環,達成自動連續射擊之目的。At this time, the firing pin 142 of the firing pin group naturally protrudes due to the rotating top of the gun bolt 14 and is resisted by the firing pin 132 combined with the reentry spring seat 15. The primer force of the secondary shot of the impact is sufficient and continuous, and is not affected by the gun. The impact force is interrupted by the impact of the machine 13's re-entry impact bolt spring 133. After firing the second round of ammunition, it enters the automatic weapon ejection, ejection, recoil, recoil, push and advance, lock and firing of the ammunition The action cycle, to achieve the purpose of automatic continuous shooting.

由於該習知技術之自動武器係為槍管後座式武器,其使用之彈藥為較高威力具有高膛壓之彈藥,彈藥底火引燃發射藥射擊時產生的後座力極高,雖然該高壓後座力提供槍管後座時之動力,該動力能帶動槍機組與復進簧座組反覆運動達到自動循環連續射擊的目的,但為了降低槍管後座力產生的震動及為了延遲開閂與傳遞槍管後座能量,槍管11與槍身10之間設置一槍管簧12,全槍除槍管11及槍閂14於擊發瞬間須能閉鎖後座運動一小段自由行程壓縮槍機簧133外,槍機13等其餘零件均受慣性力停留原處。Since the automatic weapon of the conventional technology is a barrel rear-seat weapon, the ammunition used is a high-powered ammunition with a high chamber pressure. The recoil force generated when the propellant is fired by the primer of the ammunition is extremely high. The high-pressure recoil force provides the power when the barrel is recoiled. This power can drive the gun unit and the recoil spring seat assembly to move repeatedly to achieve the purpose of automatic circulation and continuous shooting, but in order to reduce the vibration generated by the barrel recoil force and to delay the opening Barrel and transfer barrel recoil energy. A barrel spring 12 is set between barrel 11 and gun body 10. All guns except barrel 11 and barrel 14 must be able to lock the rear seat movement for a short period of free stroke at the moment of firing. Compression gun Outside the machine spring 133, the other parts such as the bolt camera 13 are all stayed in place by inertial force.

當發射藥產生之瞬間高壓氣體推動彈頭往前,由於膛壓極高,槍管11末端之槍管套111必須與槍機組之槍閂14呈閉鎖結合狀態,兩者一起後座壓縮槍管簧133儲存能量。當槍機簧133承受槍管後座力壓縮到極限時開始回彈,能量釋出便推動槍機13及復進簧座組後退,槍機13後退時,固定於槍機13之凸輪銷131亦向後,在槍閂14之凸輪槽141曲線行程限制下,槍機13帶動槍閂14旋轉並與槍管套111完成分離開閂,槍管11後退到極限位置後,因槍管簧12的簧力作用開始復進歸位。唯此種機構應用在低膛壓反衝式武器時,會因膛壓過低無法有效傳遞後座能量,進而無法連續射擊。When the propellant is generated, the high-pressure gas pushes the warhead forward. Due to the extremely high chamber pressure, the barrel sleeve 111 at the end of the barrel 11 must be in a locked state with the bolt 14 of the gun unit. Together, the rear seat compresses the barrel spring. 133 stores energy. When the bolt spring 133 is compressed to the limit with the barrel recoil force, it starts to rebound. The energy released pushes the bolt 13 and the recoil spring seat assembly to retreat. When the bolt 13 retreats, it is fixed to the cam pin 131 of the bolt 13 Also backward, under the limit of the curve stroke of the cam groove 141 of the breech block 14, the bolt 14 is driven by the bolt 14 to rotate and the bolt is separated from the barrel cover 111. After the barrel 11 retreats to the limit position, the bolt 12 is The spring force begins to return to position. Only when this kind of mechanism is used in a low-pressure recoil weapon, it will not be able to effectively transmit the energy of the recoil due to the low-bore pressure, and it will not be able to fire continuously.

再者,習知之現役各種反衝式自動武器,槍機、復進簧等後座復進能量傳遞組件,普遍無法僅以單一同軸向運動,運動時通常會產生非同軸向作用力之轉動力矩,使槍枝震動增加,降低射擊精準度。Furthermore, various recoil type automatic weapons currently in service, such as bolts, retraction springs and other recoil energy transmission components, generally cannot move in a single coaxial direction, and usually produce non-coaxial force rotation moments during movement. , To increase gun vibration and reduce shooting accuracy.

又,該習知構造具有槍管簧12以及槍閂14與槍管套111的閉鎖結構,以及擊針142、擊針頂桿132,零件數量較多,組裝較為複雜,且因膛壓較高,承受高膛壓及高後座力之零件必須較厚實,故整體武器重量較重。In addition, the conventional structure has the barrel spring 12, the latch structure of the barrel 14 and the barrel sleeve 111, as well as the firing pin 142 and the firing pin 132. The number of parts is large, the assembly is more complicated, and the chamber pressure is relatively high. , The parts that withstand high chamber pressure and high recoil must be thicker, so the overall weapon weight is heavier.

本發明之目的在於提供一種反衝式自動武器循環射擊機構,可順利傳遞中低膛壓產生之後座力,讓槍機後座到位,並減少機構零件數量,使零件尺寸重量無須太過厚實,進而降低武器重量。The purpose of the present invention is to provide a recoil type automatic weapon cyclic shooting mechanism, which can smoothly transmit the rear seat force generated by the middle and low chamber pressure, so that the back seat of the bolt is in place, and the number of mechanical parts is reduced, so that the size and weight of the parts do not need to be too thick. This reduces the weight of the weapon.

本發明之另一目的在於提供一種反衝式自動武器循環射擊機構,能減少非同軸心作用力之轉動力矩,降低槍枝震動力,並增加射擊精準度。Another object of the present invention is to provide a recoil type automatic weapon circulation shooting mechanism, which can reduce the rotational torque of the non-concentric force, reduce the vibration force of the gun, and increase the shooting accuracy.

槍機(221)因受到本身質量慣性及緩衝復進組(23)支撐力,於彈藥(24)被擊發瞬間尚停留於原處,槍機組(22)之槍機簧(223)因而受到彈藥(24)之銅殼及槍閂(222)後座擠壓儲存能量。Due to its own mass inertia and the support of the buffer reclamation unit (23), the bolt (221) stays in place at the moment the ammunition (24) is fired, and the bolt spring (223) of the bolt unit (22) is affected by the ammunition. The copper shell of (24) and the rear seat of the breech block (222) squeeze to store energy.

當槍機簧(223)承受槍閂(222)後座力壓縮到極限時開始伸張,能量釋出便推動槍機(221)及緩衝復進組(23)後退,槍機(221)後退時,固定於槍機(221)之凸輪銷(224)亦向後,由於該槍閂(222)的凸輪槽(225)為軸向直槽,槍機(221)並不會如習用構造般的帶動槍閂(222)旋轉,槍閂(222)係直線的向後運動,因此不會旋轉。When the bolt spring (223) is compressed to the limit by the recoil force of the bolt (222), the bolt spring (223) starts to stretch, and the energy is released to push the bolt machine (221) and the buffer reclamation group (23) to retreat. When the bolt machine (221) retreats , The cam pin (224) fixed to the bolt (221) is also backward, because the cam groove (225) of the bolt (222) is an axial straight groove, the bolt (221) will not drive as the conventional structure The bolt (222) rotates, and the bolt (222) moves backward in a straight line, so it does not rotate.

可同時參照圖1,相較於前述的習知射擊機構,例如第I585359號發明專利,習知機構於發射藥產生之瞬間高壓氣體推動彈頭往前,其膛壓極高,槍管(11)末端之槍管套(111)必須與槍機組之槍閂(14)呈閉鎖結合狀態。槍機(13)後退時,在槍閂(14)之曲線形狀的凸輪槽(141)行程限制下,槍機(13)帶動槍閂(14)旋轉並與槍管套(111)完成分離開閂,動作複雜且在中低膛壓後座力作用下容易消耗後座能量(非單純直線運動),而無法連續擊發。而本發明不需要設置閉鎖機構,槍閂(222)只做直線運動,能適用於中低膛壓之彈藥。Referring to Fig. 1 at the same time, compared with the aforementioned conventional shooting mechanism, such as the invention patent No. I585359, the conventional mechanism pushes the warhead forward by the high-pressure gas at the moment when the propellant is generated, and its chamber pressure is extremely high, and the barrel (11) The barrel sleeve (111) at the end must be in a locked state with the bolt (14) of the gun unit. When the bolt (13) retreats, the bolt (13) drives the bolt (14) to rotate and separates from the barrel sleeve (111) under the limit of the stroke of the curved cam groove (141) of the bolt (14) The latch has complex movements and easily consumes recoil energy (not simply a straight line movement) under the action of low and medium pressure recoil, and cannot be fired continuously. However, the present invention does not need to be provided with a locking mechanism, and the bolt (222) only moves in a straight line, which can be applied to ammunition with low and medium pressure.

槍閂(222)持續退彈殼向後,當彈殼脫離槍管套(212)時,槍身(20)的退殼挺(201)配合退殼鈎(未標示)將彈殼拋離槍身(20),完成「退殼」及「拋殼」動作。The bolt (222) continues to withdraw the cartridge case backwards. When the cartridge case is separated from the barrel sleeve (212), the ejector support (201) of the gun body (20) cooperates with the ejection hook (not marked) to throw the cartridge case away from the gun body (20) , Complete the actions of "Unpacking" and "Ejecting Shell".

緩衝復進組(23)之緩衝器(231)後退撞擊至槍身(20)底部時,完成自動循環之「後座」到位,此時,復進簧(232)開始回彈釋放能量推動緩衝器(231)的活塞及槍機組(22)往前復進,槍閂(222)下方的推彈齒(229)會推動次發彈藥(24)向前進入彈膛內,完成自動循環之「推彈」及「進彈」動作,最後槍閂(222)進入槍管套(212)內頂住槍管(211)尾端,此時,由於擊針(225)是突出的固定設置在槍閂(222)的端面,將直接撞擊次發彈藥(24)的底火,順利擊發次發彈藥(24)後,開始進入「退殼」、「拋殼」、「後座」、「復進」、「推彈」及「進彈」及「擊發」之自動武器射擊作動循環,達成自動連續射擊之目的。When the buffer (231) of the buffer reclamation group (23) retreats and hits the bottom of the gun body (20), the "rear seat" that completes the automatic cycle is in place. At this time, the recoil spring (232) starts to rebound and release energy to push the buffer The piston of the gun (231) and the gun unit (22) move forward, and the push teeth (229) under the bolt (222) will push the secondary ammunition (24) forward into the chamber to complete the automatic cycle. Push” and “inject” actions, and finally the bolt (222) enters the barrel sleeve (212) against the end of the barrel (211). At this time, because the firing pin (225) is protruding and fixed on the gun The end face of the latch (222) will directly hit the primer of the secondary ammunition (24). After the secondary ammunition (24) is successfully fired, it will start to "retract", "eject the shell", "back seat", and "return". , "Push bullet" and "Push bullet" and "Fire" automatic weapon firing cycle to achieve the purpose of automatic continuous shooting.

本發明屬於一種可連續擊發反衝式自動武器,通常使用中、低威力步槍彈或手槍彈而非全威力步槍彈,因此槍閂(222)不需要與槍管套(212)閉鎖,擊針(225)固定設置在槍閂(222)前端,槍閂(222)進入槍管套(212)內頂住槍管(211)尾端時將直接撞擊次發彈藥(24)的底火引燃發射藥,能使彈藥(24)穩定擊發。The invention belongs to a recoil type automatic weapon that can be fired continuously. It usually uses medium and low-power rifle bullets or pistol bullets instead of full-power rifle bullets. Therefore, the bolt (222) does not need to be locked with the barrel sleeve (212), and the firing needle (225) is fixedly arranged at the front end of the breech block (222), and when the breech block (222) enters the barrel sleeve (212) against the end of the barrel (211), it will directly hit the primer of the secondary ammunition (24) to ignite and launch Medicine, can make the ammunition (24) fire stably.

本發明藉由模組化設計使該機構可實施全自動射擊,由於構造更精簡能降低武器重量、減少故障的發生,並且因為主要元件皆為同軸向運動,能減少非同軸向作用力之轉動力矩,進而能增加射擊精準度。The invention uses modular design to enable the mechanism to implement fully automatic shooting. Due to the simplified structure, it can reduce the weight of the weapon and reduce the occurrence of failures, and because the main components are all coaxially moving, it can reduce the rotation of non-coaxial force. Torque, which can increase shooting accuracy.
