肉鸭掏膛机改进设计与仿真分析及试验

Design and experiment of QNZ24 type eviscerating machine for duck

针对中国肉鸭屠宰过程中,机械自动化程度低、生产效率低、设备依赖进口等问题,设计一种自动掏膛机。阐述掏膛机整机结构与工作原理,对其关键部件掏膛机械手单元进行分析,并结合凸轮曲线相关理论进行协调性设计和曲线修正与优化,利用creo3.0建立多轨迹空间圆柱凸轮的三维模型,并进行运动学仿真,对主轴进行了扭转刚度校核。验证试验结果表明:该型掏膛机在不同产量下,平均内脏器官数量完整度为94.5%,平均内脏器官形态完整度为91.06%。

In order to solve the problems in duck slaughter machinery process,including low level of automation and low production efficiency,an automatic eviscerating machine was researched and designed.Moreover,the machine structure and its working principle were analyzed.The key components of the manipulator unit were analyzed,designed in coordination and corrected its cam curves based on the related theory of cam.Creo3.0was used to establish the threedimensional model of multiple trails cylindrical cam,and the kinematics simulation was analyzed in the software at the same time,to support the cam.Spindle was analyzed and rigidity check.The test results showed that under different production,the average integrity rate of number of internal organs was 94.5%,and the average morphological integrity was 91.06%.
