工程科技数控机床毕业论文1.doc

摘要 为了适应机械行业的发展趋势，简化一般工厂中工人的劳动量，在本设计中应用简单的数控系统设计。就实际情况分析，一般的机械加工精度和效率足以完成工作需求，不需要高精密的数控系统，但考虑一般机械系统实现自动化生产相对比较困难，而且实现起来相当复杂，设备比较庞大。然而这些问题可以在一个非常简单的数控系统中很容易的得到很好的解决。随着微型计算机系统的发展，性能的不断提高，大范围应用的普及，应用一个简单的数控系统来完成一般的工作，在一般的小型工厂中足可以实现。 本次设计的铣床，除了能进行铣削加工，主轴上安装不同的刀具时，还可以进行钻孔或攻丝加工。所以我们采用了如下的设计方案：进给系统采用大惯量宽调速直流伺服电动机，滚珠丝杠，双螺母垫片调整预紧间隙，导轨副采用直线滚动导轨副，主传动系统采用无级调速电机。 在设计过程中，我得到了老师的精心指导，帮我收集了很多我无法找到的资料。袁老师在完成繁重的教学任务之余，经常拖着疲惫的身体，对我们的工作进行仔细地审查，针对我们的情况，进行了耐心的讲解，从设计的原理到结构功能，做出了大量的指导性工作，使我们对所要设计的课题有了更深的了解，在这里也要感谢同组同学的热心帮助，同学们总是微笑着面对我的提问，耐心讲解，使我对有些问题有更加清楚的认识。 关键词：总体结构布局 铣床传动方式 主传动系统 进给系统 Abstrac In order to adapt to the machinery industry development trends, simplified general factory workers in the labor, in the design of a simple numerical control system design. On the actual situation analysis, the general machining accuracy and efficiency needs to complete its work, do not need high-precision numerical control system, but considering the general mechanical system to automate production is relatively difficult and very complex to achieve, equipment relatively large. However, these problems can be in a very simple numerical control system in very easy to get a good solution. With the development of micro-computer system, the continuous improvement of performance, large-scale application of the universal application of a simple numerical control system to complete the work in general, the small factories in general can be achieved in full. The processing center, in addition to a milling, spindle installed on a different tool, can also carry out drilling or tapping processing. Therefore, we have adopted the design of the programmes are as follows: feeding system using the inertia of wide speed range DC servo motor, ball screw, double-nut pads adjust preload gap, the rails of a rail line rolling deputy, the main drive system adopts the - Speed Motor. In the design process, I was given the careful guidance of teachers Hsu, To help me collect a lot I can not find the information. Yuan te
