摘要：在工业生产中，自动气压机的自动与速度发挥了巨大的作用和实际效益，此次设计基于改公司购买的气压机靠手动操作，效率低，操作人员工作强度高，并且无法控制产品是否合格，对整个洗衣机离合器的质量造成影响。因此对气压机进行改进，改进后使粉围轴承压入壳体盖，保证在压力范围内压入，大大的提高了工作效率，最主要是保证了压合的力在设定范围内，保证了产品的可靠性。可编程序控制器产生于二十世纪六十年代，经过几十年的发展，已成为以微处理器为核心，综合微电子技术、自动化技术、网路通信技术于一体的通用工业控制装置。它可靠性高、使用方便、性能价格比高。从世界范围来看，PLC是用的最多、应用范围最广的自动化产品，也可以说是最实用的自动化产品。本设计是PLC在电机控制方面的一个应用，因为用PLC来实现自动有很多优点，可使系统的硬件设备大为简化，体积减小，而且PLC的抗干扰能力强，可靠性高，操作维护简单。

Abstract:In industrial production, automatic air pressure machine and the automatic speed played a huge role and real benefits Based on the current design of the companies buying pressure on manually operated machines, inefficient and high-intensity work, and unable to control whether a product passes, the whole Clutch have affected the quality. So the pressure for improvements, improvements have enabled powder Wai bearings pressed into the shell cover, and ensure that the pressure within the indentation, greatly increase the efficiency of its work, the most important is to ensure that the bond strength at the set point, ensuring the reliability of the product. PLC have in the 20th century the 1960s, after decades of development, has become a microprocessor to the core, integrated microelectronics technology, automation technology, network communications technology in the integration of common industrial control devices. Its high reliability, easy to use, high performance-cost ratio. On a worldwide scale, PLC is the largest, most extensive scope of application of automation products, can be said to be the most practical automation products. The design of the PLC in the electrical control of an application, because the PLC to automatically have a lot of strengths, The system will greatly simplify the hardware and the volume was reduced, and PLC anti-interference capability, high reliability, operation and maintenance simple.
