双初速自动机专用弹匣设计
摘要双初速自动机专用弹匣是实现两种弹丸供弹并确保发射过程安全可靠的重要部件，双初速自动机是通过使用不同的弹匣，改变弹匣扣的位置，从而改变与弹匣扣通过弹力变换杆连接的阻铁的位置，实现两个枪机的运动。使用非致命弹弹匣时，大枪机被阻铁挡住，小枪机运动；使用致命弹弹匣时，大枪机与小枪机同步运动。59603

Title Design of special magazine for double velocity automata
Abstract The special magazine of the double velocity automata is used to realize the two kinds of projectile ammunition handling and to ensure that emission process is safe and reliable. Double velocity automaton is through the use of different magazine, and changes the position of magazine button, which changes the position of the resistance iron that connected with the magazine buckle by elastic transformation, implement two movement of the bolt. When using non-lethal magazines, the big bolt is blocked by resistance iron, the small bolt move; when using lethal magazines, the big bolt and the small bolt move synchronously.
Some designs and researches have been done in this paper about the double velocity automata special magazine. And this includes magazine design, follower design, magazine spring design, spring timeliness calculation and feeder design. The magazine can realize two projectiles of the velocity automata pairs to be fed, and ensure the launch process is safe.
The double velocity automata special magazine research is basined on the analysis of working mechanism of double velocity automata, then propose the overall scheme of the magazine, and do related calculation and structural design.
Many aspects calculation have been done in this article to get the concrete data of the double velocity automaton magazine, and then is the 3D diagram of every part and the overall assembly drawings.
Keywords Double velocity automata； Magazine； Input bullet； Prismatic spiral spring； Buckle bullet tine.
