摘要：根据摆弹机工作特点和给定的炮弹要求和摆弹角度范围等，对摆弹机构进行了结构设计。本结构设计在摆弹的同时可以进行输弹，节省了炮弹发射的时间，提高了炮弹发射率。该结构采用了齿轮齿条传动推动摆臂摆动，链轮链条传动来输送炮弹。齿轮齿条传动组件中通过伺服电机驱动，并设有齿条导向压紧装置，能使齿条与齿轮正确啮合并沿正确的轨道运动，提高了摆臂摆动的准确性。链轮链条输送组件中通过伺服电机驱动，托板装在链条上随着链条运动来拖动炮弹向上运输。炮管顶部设有挡板，防止炮弹在输送过程中掉落，提高了炮弹传输的稳定性。为了方便炮弹传输时的故障检查，该摆弹机结构将炮管设计成开合式，炮管两部分一边通过合页转动，一边通过搭扣锁将炮管闭合。

Abstract：According to the characteristics of the ammunition swing device and the requirements of a given shell and the range of the angle of swing,the structure of the ammunition swing device was designed.The structure of the design can swing and transport at the same time,saving shells fired time,improving the shell firing rate.The structure uses  rack and pinion drive to promote the swing arm swing .The structure uses sprocket and chain drive to deliver shells.The rack and pinion drive is driven by a servo motor,and equipped with rack-oriented compression device.The rack-oriented compression device allows the rack to properly engage and move along the correct orbit,improving the swing arm swing accuracy.The sprocket chain conveyor is driven by a servo motor.The pallet is mounted on the chain and the barrel moves with the chain movement.The top of the barrel has a baffle to prevent the shells from falling during transport and improve the stability of the shells.In order to facilitate the detection of shells when the transmission failure,the structure of the pendulum machine will be designed to open and close the barrel.Two parts of the barrel through the hinge rotation, while the buckle through the clasp closed.

Keywords:Ammunition swing device；Rack and pinion；Sprocket chain
