【摘要】：随着中国制造在世界上的地位不断深入和稳固,大量的机械加工和产品制造在全国各个不同的地区完成。目前除了国有大型企业外,出现了许多外包型小微企业,他们是大中型加工企业生产链中,利润最低、耗费劳动力最多的相关工序主要解决完成的组成部分。在这些小微企业中,大量的人力在完成钻孔、攻丝、去毛刺等钳工工序内容。随着先进制造工艺的出现,加工制造利润的降低,传统加工制造的小微企业已经很难生存,故本论文针对当前现状,为小微企业设计一种低成本的加工设备——经济型钻孔攻丝机的控制系统。本论文以钻孔、攻丝类手动操作设备为对象进行设计和改造,提出面向钻孔、攻丝机的运动控制系统。本文对基于单片机、ARM、PC以及PLC等运动控制系统的研究,最终以基于PLC为载体的运动控制系统进行设计,对面向钻孔攻丝的运动控制系统进行了系统的研究和设计。首先本文在文献阅读阶段查阅了国内外相关技术的研究状况,发现在各行业中都有关于运动控制的技术描述,但是没有专门针对钻孔攻丝机进行运动控制的解决方案。其次通过对现有技术的研究,在本论文中比选了基于单片机、ARM、PC等相关技术的解决方案。通过对稳定性,开发成本,开发难度等因素对比讲述该系统的设计过程。阐述了伺服电机的选型,通过对被控对象初步的设想和计算,对控制系统的参数进行了设计,并选定了伺服系统和伺服电机。最后通过了硬件系统的确定,设计了运动控制系统的电气控制系统。以PLC为控制系统核心的设计方法,简化了一般辅助控制电路的线路,使控制系统实现了模块化。在完成以上基础工作后,设计了基于PLC的运动控制系统软件和对应的人机界面,使被控对象图形化操作,完成了运动控制系统的需求。通过以上的研究过程,设计了钻孔攻丝机的运动功能模块和操作图形模块,并结合控制软件形成了一个完整的PLC运动控制系统。
[Abstract]:As the status of Chinese manufacture in the world is deepening and steady, a large number of mechanical processing and product manufacturing in different regions of the country completed.At present, there are many outsourced small and micro enterprises in addition to large state-owned enterprises. They are the components of the production chain of large and medium-sized processing enterprises, which have the lowest profit and consume the most labor force.In these micro-enterprises, a lot of manpower in drilling, tapping, deburring and other fitter procedures.With the appearance of advanced manufacturing technology and the decrease of manufacturing profit, it is difficult for small and micro enterprises to survive, so this paper aims at the current situation.The control system of economical drilling and tapping machine is designed for small and micro enterprises.In this paper, the drilling and tapping manual operation equipment is designed and reformed, and the motion control system for drilling and tapping machine is put forward.In this paper, the motion control system based on single chip microcomputer and PLC is studied. Finally, the motion control system based on PLC is designed, and the motion control system for drilling tapping is studied and designed systematically.First of all, in the literature reading stage, this paper looked up the research status of related technology at home and abroad, found that there is a technical description of motion control in every industry, but there is no specific solution for motion control of drill tapping machine.Secondly, through the research of the existing technology, this paper compares the solutions based on SCM / ARMPC and other related technologies.The design process of the system is described by comparing the stability, development cost, development difficulty and other factors.This paper expounds the selection of servo motor, designs the parameters of the control system through the preliminary assumption and calculation of the controlled object, and selects the servo system and servo motor.Finally, the electrical control system of motion control system is designed through the determination of hardware system.The design method of PLC as the core of the control system simplifies the circuit of the general auxiliary control circuit and makes the control system modularized.After completing the above basic work, the software of motion control system based on PLC and the corresponding man-machine interface are designed, which make the controlled object operate graphically and fulfill the requirement of the motion control system.Through the above research process, the motion function module and the operation graph module of the drill tapping machine are designed, and a complete PLC motion control system is formed by combining with the control software.
