Title Design of Automated Production Lines for Axis and Sleeve Parts Assembling
Abstract
Pneumatic technology is an effective means of automation and mechanization of the production process, witch is fast, efficient, clean, safe, low cost and easy to maintain. It has been widely used, especially in a variety of automated production line. The paper describes the design of a automated production line used for axis and sleeve parts assembling. The specific design work includes these: ①According to the work requirements of the assembly system, analyze and identify the process of the action of the pneumatic system. On this basis, design the overall program of the axis and sleeve parts Automatic assembly line, including the circuit design of the pneumatic system and the selection of pneumatic components. ②Design the mechanical structure of the automatic assembly line, so as to meet the work requirements for the loading ,unloading and assembly of different parts, and has a compact structure. Using PLC to achieve the requirements of the order of action of the automatic assembly of axis and sleeve parts, and design the PLC control program. Two pneumatic manipulators and a stamping assembly device are designed, and they can work together to load and unload axis and sleeve parts and assemble them.
Keywords pneumatic technology, manipulator, assembly, PLC control

1.1 气动自动装配生产线的研究意义
在零件装配的过程中，冲压是一道常用的工序，它可以快速地将两个零件嵌套在一起。目前轴套类零件的冲压装配主要由人工进行上下料，大批量生产需要大量工人的简单重复劳动, 工作效率低,劳动强度大，且冲床伤手的事故频繁发生[1]。因此探讨如何实现轴套类零件的自动装配问题就显得很有意义。
