喷砂机设计毕业设计论文.doc

中文摘要 随着社会经济的发展和科学技术水平的提高，对工业生产提出了更高的要求，从数量到质量、从材料到结构等都经历了一次又一次的技术革新。从原始的钳工，到普通机床，再到如今的数控机床，生产作业工具在日新月异地更新。对于精加工，有数控车、铣、镗、磨，有特种加工、电火花加工；而对于没有余量的表面机械加工，就需要用到喷砂机了。喷砂机类型可分为：吸入式喷砂机、压入式喷砂机、液体喷砂机、冷却喷砂机等。目前，喷砂机工作方式大多是利用继电器、开关和按钮进行控制；因此，喷砂机存在着一些缺陷。譬如，继电器、按钮、开关易疲劳受损、易受腐蚀、误动作等诸多故障，喷砂机机体密封性不够好易造成磨料泄漏回收难、污染环境等。综上，针对上述弊端，在此设计中对喷砂机进行现代化改进；与PLC、触摸屏进行现代化工艺结合，改善其使用方式和工作方式，使之应用面更广，使之符合现代化、智能化控制的要求。对在舱室中的砂进行吸收再利用。 在此次设计中，利用基于STM32单片机的自制简易三菱FX系列PLC与现在主流的组态软件MCGS、触摸屏相结合的方式实现对喷砂机运行的智能化控制和实时监控；利用各种各样的传感器实现自动运行，实现了成本低廉、性能优异的对喷砂机的智能化改造。 关键词：喷砂机，MCGS，触摸屏，自动化 ABSTRACT With the social and economic development and scientific and technological level of industrial production has put forward higher requirements, from quantity to quality, from materials to structure and so once again experienced a technological innovation. From the original fitter, to general machine tools, to todays CNC machine tools, production operations tools in a rapidly changing updated. For finishing, a CNC turning, milling, boring, grinding, there are special processing, EDM; while no margin for surface machining, you need to use a sandblasting machine. Blasting machine types can be divided into: suction blasting machine, pressure-blasting machine, liquid sandblasting machine, sandblasting machine cooling. Currently, work is mostly sand blasting machines use relays, switches and buttons to control; therefore, sandblasting machine there are some flaws. For example, relays, buttons, switches fatigue damage, susceptible to corrosion, malfunction, and many failures, sandblasting machine body is not good enough seal leakage could easily lead to abrasive recycling difficult, and environmental pollution. In summary, for the above-mentioned drawbacks, in this design for sandblasting machine modern improvements; with PLC, touch screen technology combined to modernize and improve its use and work to make it wider application, to conform to modern, intelligent control requirements. Sand in compartment to absorb and reuse. In this desi
