基于plc和变频器的t610卧式镗床电气控制系统设计-终期论文毕业论文.docVIP

摘 要 T610型卧式镗床是钻孔领域不可或缺的一员。原因归结于卧式型的镗床不仅仅是拓展工件上的已经存在的或已经加工完成后的孔，卧式型的这种镗床的特色在于它能够铣削、加工外圆和螺纹以及其他。最初的T610卧式镗床出现电气故障的频率总体来说较高的原因是由于继电器控制系统的选备，不仅仅是维修保养费时费力的问题，经济消耗较高。出现这些故障的原因是继电器控制系统的配置选择。在本次的毕业设计中经过甄选，决定使用西门子S7-200PLC，主要处于对经济效益的考虑，以及任务的完成度，在变频器方面综合考虑最终选择MM440.用这两个器件综合改善传统卧式镗床的不足，提升生产质量。 关键词：T610卧式镗床，电气控制，PLC变频器 ABSTRACT In contemporary construction scale and metal cutting processing in all machinery manufacturing entrenched exercised position, mechanical manufacturing work forty to sixty percent is occupy its. However, the boring machine is a role play a decisive role. Around 1770, was born the first original horizontal boring machine. With the development of science and technology breakthrough rapid pace, processing all kinds of complicated large parts of the horizontal boring machine successfully developed in 1999. The continuous development of boring machine is precisely due to the processing of parts of the constantly changing, with general, million years of characteristics of horizontal boring machine eventually develop variable as a leader in contemporary boring machine is also reasonable. In the processing of holes, T610 this type of horizontal boring machine occupies a very important position. Attributed to type horizontal boring machine is not only expand the holes on the device already exists or has been manufactured after, the characteristics of Horizontal type boring machine is it can be milling, machining circle and threads and other. Traditional T610 horizontal boring machine due to the relatively high frequency of the relay control system of electrical accidents. In addition Repair and maintenance difficult and expensive, the fault reason is the configuration selection of relay control system. In the graduation design, after selection, the final decision to use Siemens S7-200 PLC, Mainly in the economic benefits of the consideration, and task completion, Considering in the final selection of MM440 inverter. With these two devices are integrated to impro
