PLC型号选择(分析控制电路，确定需要输入/输出点数，从而选择适当的PLC型号，以满足控制要求）4. 画出PLC的外部接线图（包括I/O地址的分配、以及所需的接触器，按钮开关等电器。） 研究意义通过对双面铣钻组合机床的研究制作，来实现组合PLC机床的设计，使理论知识与实践更好结合、提高综合运用所学知识和设计能力的目的。普通车床是应用非常广泛的金属切削工具,目前采用传统的继电气控制的普通车床在中小企业人大量使用。由于继电器系统接线复杂,故障诊断与排除困难，并存在：触电易被电弧烧坏而导致接触不良，机械方式实现的触点控制反应速度慢，继电器的控制功能被固定在线路中，功能单一灵活性差等缺点。因而造成了这些企业的生产率低下效益差，反过来这些企业有没有足够的资金购买新的数控机床。因次当务之就是急对这些普通车床进行技术改造，以提高企业的设备利用率，提高产品的质量和产量。由于PLC具有通用性适应性强，完善的故障自诊断能力且维修方便，可靠性高及柔韧性等优点。在可编程序控制器问世之前，继电器接触器在工业领域中占主导地位。继电器接触器控制系统是采用固定接线的硬件实现控制逻辑。如果生产工艺或生产任务发生变化，就必须重新设计，改变硬件结构，这样造成时间和资金的浪费。另外，大型控制系统用继电器和接触器控制，使用的继电器数目越多，控制的体积越大，耗电多，且继电器触电为机械触点，工作频率较低，在频繁动作的情况下寿命较短，造成系统故障，系统可靠性差。为了解决这一问题，早在1968年，美国最大的汽车制造商通用汽车公司，为了适应汽车型号不断翻新，以求在激烈竞争的汽车工业中占有优势，提出要用一种新型控制装置来取代继电器接触器控制装置，并且对未来的新型控制装置做具体的设想，药把计算机的完备功能以及灵活性、通用性号等优点溶于新的控制装置中，且要求新的控制装置编程简单，使得步熟悉计算机的人员也能很快掌握它的使用技术。PLC是综合继电器接触器控制的优点及计算机灵活、方便、的有点而设计制造和发展的，这就使得PLC具有许多其他控制器所无法相比的特点：可靠性高，抗干扰能力强；通用性强，使用方便；采用模块化结构，使系统组合灵活方便；编程语言简单、易学，便于掌握；系统设计周期短；对生产工艺改变适应性强；安装简单，调试方便、维护工作量小。三、国内外现状和发展趋势在我国，组合机床已有28年的发展历史，其科研和生产都具有相当的基础，应用也以深入到很多行业。是当前机械制造业实现产品和更新，进行技术改造，提高生产效率和高速发展必不可少的设备之一。组合机床及其自动线是集机电于一体的合自动化程度较高的制造技术和成套工艺装备。他的特征是高效、高质、经济实用，而被广泛应用于工程机械、交通、能源、军工、轻工、家电等行业。我国传统的组合机床及组合机床自动线主要采用机、电、气、液压控制，他的加工对象主要是生产批量比较大的大中型箱体类和轴类零件，完成钻孔、扩孔、铰孔，加工，各种螺纹、镗孔、车端面和凸台，在孔内镗各种形状槽，以及铣削平面和成行面等。组合机床的分类繁多，有大型组合机床和小型组合机床，有单面、双面、三面、卧式、立式、复合式，还有多工位回转台式组合机床等；随着技术的不断进步，一种新型的组合机床柔性组合机床越来越受到人们的青睐，他应用多位主轴箱、可换主轴箱、编码随行夹具和刀具的自动更换，配以可编程序控制器（PLC）、数字控制（NC）等。能任意改变工作循环控制和驱动系统，并能灵活适应多品种加工的可调可变的组合机床。另外，近年来组合机床加工中心、数控组合机床等在组合机床行业中所占份额也越来越大。由于组合机床及其自动线是一种技术合性很高技术专业产品，是根据用户特殊要求而设计的，他涉及到加工工艺、刀具、测量、控制、诊断监控、清洗、装配和试漏等技术。我国组合机床及其组合机床自动线总技术水平比发达国家要落后，国内所需的一些高水平组合机床及自动线几乎都从国外进口。工艺装备的大量进口势必导致投资规模的扩大，并使产品成本提高。因此，市场不断要求我们开发新技术、新工艺，研制新产品，由过去的“刚性”机床结构，向“柔性”化方向发展，满足用户需求，真正成为刚柔兼备的自动化装备。四、设计内容、途径及技术路线 研究内容1实现PLC机床的设计。2PLC代替继电器接触器电气控制电路。3建立PLC控制模型，并实现仿真。4完成硬件设计和软件编程，并进行调试 研究途径收集相关资料和文献，系统学习PLC控制系统，按照继电器接触器控制电路选择PLC号，在PLC编程软件上建立完整仿真模型制作硬件和软件并调试。 技术路线1熟悉组合机床PLC控制系统在生活中的应用。2运用FXPG/WIN-C软件按照所设计电气控制进行编程，在仿真机上进行仿真，并和继电器接触器控制系统作比较，更进一步认识PLC。3保证组合机床在各传动链中保持良好的机械特性，并对其在调试中能进行检修，熟悉机床内部结构和各个电机所控制执行件。4实现组合机床加工工艺流程。五、设计工作的主要阶段、进度和指标阶段起始日期终止日期进度技术指标第一阶段2013.072013.08完成选题和资料收集丰富全面第二阶段2013.082013.09控制器设计仿真及训练符合精度要求第三阶段2013.092013.10完成硬件设计和软件编程设计合理结构化、模块化第四阶段2013.102013.11进行在线调试实现制动控制第五阶段2013.112013.11编写论文准备答辩详细全面六、最终目标及完成时间所设计的PLC控制系统能准确无误的完成各个控制环节，在实验台上进行调试并能进行自动循环和手动调整操作。2013年10月完成论文“双面钻铣组合机床PLC电气控制系统设计”。七、现有条件及必须采取的措施PLC可编程控制器实验室，电气自动化控制实验室，电子电路实验室，电工实验室。 必须措施：现有条件上还需开发基于PLC控制机床并编制相应控制软件。八、协作单位及要解决的主要问题协作单位：学院PLC实验室。所要解决本课题的主要问题是：控制策略的开发和仿真，以及PLC的设计、制作和调试。如条件允许，需解决：购买专用于PLC开发的集成芯片及开发软件，购买用于继电器接触器电路设计的较精确的实验仪器及电控产品开发周期的快速成型系统软件。摘 要双面钻铣组合机床PLC控制系统设计121 2practices.

Combined machine is horizontal, set hydraulic power slipway for mobile workstations, using trip control and hydraulic transmission; it can be used for semi-automatic processing cycle and manual adjustment. Clamping of work piece uses hydraulic control system (relaxation) which has circuit lost electrical clamping function to clamp processed parts, in a semi-automatic cycle, the work piece carried out two position milling, drilling process (For each position have been quick feed and feed two-step), each of the two position completes the digital processing. The first position is the double-sided milling: Milling head installs two sides of the worktable, milling cutter does rotary movement, in the table to work from the fast-forward into the time table for clamping the work piece in the milling process. The second position is a two-sided drill; it consists of two drill box. Drill process consists two positions. Dua
