中文摘要:
      目的 为自动化灌装生产线设计一种新型的自动封盖机械,实现对批量桶盖的自动拆分、抓取、翻转移动、下压动作。方法 以单个气缸作为封盖机的唯一动力,采用特殊的曲柄摇块机构,将气缸的直线运动转化为末端执行机构的复合运动,实现封盖过程。通过Pro/E机构运动学仿真,验证运动过程轨迹。结果 推导出曲柄摇块机构末端位置方程。建立了机构的运动仿真模型,通过运动学仿真得到末端执行机构的位置和速度曲线,以及盖体运动过程中所占用的空间范围,验证了该设计的可行性,缩短了产品的开发周期。结论 采用曲柄摇块机构完成封盖机运动过程的集成,通过单一动力源实现自动封盖机功能。设备结构简便、易操作、工作效率高、稳定性好,便于与各类灌装机械相集成。
英文摘要:
      The work aims to design a new type of automatic capping machine of the automatic filling production line, to achieve the automatic separation, grabbing, tumbling and moving and pushing down of the mass produced covers. With single cylinder as the only power, the capping machine was designed based on a special crank rocker mechanism, which turned the rectilinear movement of the cylinder into compound movement of the end actuator to achieve the capping process. The movement trajectory was verified through mechanism kinematic simulation in Pro/E. The end position equation of the crank rocker mechanism was derived. The motion simulation model of the mechanism was established. The position and velocity curve of the end effector as well as the spatial range occupied by the movement of the cover body were obtained through kinematics simulation. The feasibility of the design was verified and the development cycle of the products was shortened. The crank rocker mechanism is used to complete the integration of capping machine movement process, and the functions of automatic capping machine are achieved through a single power source. The capping machine, characterized by simple structure, easy operation, high working efficiency and good stability, can be easily integrated with all kinds of filling machinery.
