大学数控机床的经济型改造计算说明书..docxVIP

摘 要中国是一个古老的传统的工业大国，但其装备非常落后于发达国家，大多数企业还沿用着一些旧的机床，而随着时代的发展，客户对零件的要求越来越高，包括加工精度、批量小、形状复杂等特点。而这些旧式机床显然不能满足客户需求。数控机床在自动化方面，加工精度方面，劳动强度等都比较先进。如果大批量购进数控机床，尤其是更大型的机床。价格非常昂贵，一般的企业很难承受得起。况且中国目前有成千上万的普通机床，如果全部丢掉，那代价是非常的大。基于西方国家对普通机床改造的经验，我们可以借鉴。对我国普通机床进行数控化改造，这样既节约了成本，又降低了工人的劳动强度。本文主要论述了数控机床的现状，对机床进给系统的改造，包括纵向进给系统的设计和横向进给系统设计。电动机的选择，以及电动刀架的设计。本文主要讲了进给系统的设计与计算，包括纵横向系统设计，纵横向系统计算，纵横向切削力计算，纵横向滚珠丝杠计算。总而言之，我们对普通机床进行数控改造，这将有益于我国社会主义建设。有益于新时期国家的发展，有益于我国工业的发展 。关键词：普通机床；数控改造；数控机床AbstractChina is an ancient tradition of manufacturing power, but its equipment is very backward, most companies still use the old machine tool, and with the development of The Times, the customer is more and more high to the requirement of parts, including machining precision, small batch and complex shape, etc. The old machine tool obviously cant meet the demand of customers. Nc machine tool in terms of automation, machining accuracy, the intensity of labor, etc are advanced. If the bulk purchase nc machine tools, especially the larger machine. Price is very expensive, general enterprises are difficult to afford. Besides, China now has hundreds of thousands of ordinary machine tool, if lost everything, that price is very big. Based on western experience for the modification of the ordinary machine tool, we can draw lessons from. To common machine tool numerical control reform in our country, this saves the cost and then reduce the labor intensity of workers.This paper mainly discusses the present situation of nc machine tools, transformation of machine tool feed system, including the longitudinal feed system design and the transverse feed system design. The choice of motor, and the design of the electric tool post.This article is mainly about the design of feed system and computing, including vertical and horizontal to the system design, the vertical and horizontal to the system calculation, vertical and horizontal to the cutting force calculation, vertical and horizontal to the ball screw is calculated.To su
