【摘要】：柔性制造系统(Flexible Manufacturing System)是一个由计算机集成管理和控制,制造中小批量多品种零部件的自动化制造系统。该种系统具有柔性高、加工准备时间短、设备利用率高和加工质量高等特点。风机作为工业中最主要的抽风和排风设备,市场需求量一直居高不下,而企业的生产能力又一直跟不上,这就使得企业急需提高其自动化制造水平。本文所介绍的是风机连接件,其作用是连接通风口和通风软管。现在市面上还没有针对这种连接件的专用加工系统,本论文将首次研发这套系统以满足企业的加工需求。本文所介绍的这类连接件其结构是由四根管道法兰连接而成,其中管道法兰有八种不同的规格,每种不同规格的法兰有不同的加工要求,其中主要的加工要求有打侧孔、打底孔、切断和切边。为了满足不同规格法兰的加工,要求制造系统要有足够的机械柔性和控制柔性。从机械结构的角度看,每个加工模块的结构要能够同时满足所有法兰的加工需求,这就要求各个模块内部要具有足够的机械柔性。同时各个模块之间的连接要足够稳定、协调性要足够好,保证所有法兰都能够平稳的进出各个加工模块,这要求整个系统的机械柔性要足够好。从程序控制的角度看,不同规格法兰的加工要求不同,这就要求控制系统能够判断出待加工法兰的种类,并启动相应的控制程序。在打侧孔时,不同规格的法兰,其侧孔的孔间距是变量,所以控制系统要能够适应不同孔间距的打孔。同时在系统出现故障时,控制系统要能够自动检测出故障点,并自动查找故障原因。本文根据企业的实际生产需求,针对箱式风机管道法兰设计了合理的柔性制造系统。论文的主要内容有：分析法兰结构和加工任务,确定系统加工模块；分析企业需求和生产周期等内容,确定系统自动化程度和系统整体结构布局；对制造系统的具体机械实现方案进行设计,详述了设计过程和设计原则；在详细分析系统控制柔性的基础上,完成了系统的电气控制和系统软件设计；研制出样机,并申请了发明专利。
[Abstract]:Flexible Manufacturing System (FMS) is an automated manufacturing system that is integrated and managed by a computer to make small and medium sized and multiple parts. This system has high flexibility, short processing time, high equipment utilization and high processing quality. The fan is the most important pump and exhaust in industry. Equipment, the market demand has been high, and the production capacity of the enterprise has been unable to keep up, which makes the enterprise urgent to improve its automation manufacturing level. This article introduces the fan connector, which is connected to the air vent and ventilation hose. Now there is no special processing system for such connectors on the market. This paper will be done in this paper. This kind of system is developed for the first time to meet the processing requirements of the enterprise. The structure of this type of connector introduced in this article is made up of four pipe flanges, in which the pipe flanges have eight different specifications. Each type of flange has different processing requirements. The main addition requires a side hole, a bottom hole, a cut off and a cutting edge. The processing of different specifications flange requires that the manufacturing system should have sufficient mechanical flexibility and control flexibility. From the point of view of the mechanical structure, the structure of each machining module should meet the processing requirements of all flanges at the same time. This requires that each module should have sufficient mechanical flexibility within each module. It is stable enough, and the coordination should be good enough to ensure that all flanges can move in and out of each processing module smoothly. This requires that the mechanical flexibility of the whole system is good enough. From the point of view of program control, the processing requirements of the flanges of different specifications are different. This requires the control system to determine the type of the flanges to be processed and start the corresponding control. The control system should be able to adapt to the hole spacing between different holes. At the same time, when the system fails, the control system can automatically detect the fault point and find the cause of the failure automatically. This article is based on the actual production demand of the enterprise, and is aimed at box wind. The main contents of the paper are as follows: analyze the structure and task of the flange, determine the processing module of the system, analyze the requirements and production cycle of the enterprise, determine the degree of automation and the overall layout of the system, and design the specific implementation scheme of the manufacturing system. The design process and design principles are described. On the basis of detailed analysis of the control flexibility of the system, the electrical control and system software design of the system are completed, the prototype is developed and the invention patent is applied.
