攻丝主轴箱设计 摘 要 机械制造业是一个国家经济发展的重要支柱。而制造业的生产能力主要取决于制造装备——机床的先进程度。组合机床是以通用部件为基础，配以按工件特定形状和加工工艺设计的专用部件和夹具，组成的半自动或自动专用机床。加工一种(或几种)零件的一道(或几道)工序的高效率的专用机床 无论是机械电气或液压电气控制都能实现自动循环半自动化机床采用多轴、多刀、多工序、多面或多工位同时工方式，生产效率比通用机床高几倍至几十倍。组合机床兼有低成本和高效率的优点，在大批、大量生产中得到广泛应用，并可用以组成自动生产线。由于通用部件已经标准化和系列化，可根据需要灵活配置，能缩短设计和制造周期。多轴箱是组合机床的核心部件。它是选用通用零件，按专用要求进行设计的，在组合机床设计的过程中，是工作量较大的部件之一。它是根据工序图和加工示意图所确定的工件加工孔的数量和位置，切削用量和主轴类型设计的传递各主轴运动的动力部件其动力来自通用的动力箱根据要加工的零件尺寸进行组合机床通用多轴箱的设计，绘制多轴箱原始依据图，确定主轴和齿轮模数，确定出传动系统，计算出主轴和传动轴的坐标。The machinery Manufacture is an important pillar of economic development in a country. While the capability of production in trade of manufacture mostly depends on the advanced producing equipment－machine tool . The aggregate machine-tool is take the general part as a foundation, matches by presses the work piece specific shape and the processing technological design special-purpose part and the jig, the composition semiautomatic or the automatic special purpose machine. As a Modular?machine?tool of a process (or several) Part of a (or several Road) processes for the high efficiency of the machine, is an automated or semi-automated machine tools, whether electrical machinery Electrical or hydraulic control can achieve automatic cycle, the combination of semi-automatic machine. The aggregate machine-tool selects the method which generally multiple spindle, the multi-knives, the multi-working procedures, many or the multi-locations simultaneously process, production efficiency ratio general engine bed high several times to several dozens times. As an efficient machine tool, modular machine tools have advantages of high efficiency and low cost. It is widely used in large batch production and can be consisted automatic production line .Because the general part already the standardization and the seriation, might according to need to dispose nimbly, could reduce the design and the manufacturing cycle. The multi-axle-boxes are aggregate machine-tools core parts. It selec
