设计总说明
  
    次毕业设计是基于导师在工厂的多年的工作经验自选的设计课题。同时也是基于专机的日益增加企且有单一工件大批量的生产效率高。 
    随着现代化工业技术的快速发展，特别是随着它在自动化领域内的快速发展，专机的研究已经成为当今机器制造界的一个重要方向，在现代工业运用中，大多数机器的设计和制造都是用机床大批量完成的。现代大型工业技术的飞速发展，降低了专机的实现成本， 软件支持机制也使得实现变得更为简单，因此，研究专机的设计具有十分重要的理论意义和现实意义。 
   在工业高速发展的现代化浪潮中，各种机械设计和制造业中，专机的应用越来越广泛，越来越转化为生产力，从这个意义上讲，对专机的研究具有重要的现实意义。专机是根据工件加工需要，以通用部件为基础，配以少量专用部件组成的一种高效专用机床。专机是按系列化标准化设计的通用部件和按被加工零件的形状及加工工艺要求设计的专用部件组成的专用机床。由于通用部件已经标准化和系列化，可根据需要灵活配置，从而缩短了设计和制造的周期，因此，专机兼有低成本和高效率的优点，在大批、大量生产中得到了广泛的应用，并可用以组成自动生产线 。
   专机是一种专用高效自动化技术装备，目前，由于它仍是大批量机械产品实现高效、高质量和经济性生产的关键装备，因而被广泛应用于汽车、拖拉机、内燃机和压缩机等许多工业生产领域。其中，特别是汽车工业，是专机最大的用户。如德国大众汽车厂在 Salzgitter 的发动机工厂，在大批量生产的机械工业部门，大量采用的设备是专机。因此，专机的技术性能和综合自动化水平，在很大程度上决定了这些工业部门产品的生产效率、产品质量和企业生产组织的结构，也在很大程度上决定了企业产品的竞争力。
B型三支管是使用在水暖管道上的重要部件，为热水提供多支分流通道。为了提高加工这三个 M8 的螺纹孔的效率和质量，采用专机进行加工，机床设计三个 轴同时加工三个M8 的螺纹孔，这样能使螺纹孔之间的距离得到精确的保证，使用专机同 时可以使得加工效率提高倍，同时大大提高螺纹质量，减轻操作工人的劳动强度。 
    本次设计工作将设计一台立式四轴攻丝专机。因此，目的是使设计出的机床结构简单、使用方便、效率高、质量好。从而选择最佳的工艺方案，合适地确定机床工序集中程度，合理地选择专机的通用部件，恰当的专机的配置型式，合理地选择切削用量，以及设计高效率的工具、刀具及主轴箱就是本次设计主要内容。具体的工作就是要制定工艺方案，进行机床结构方案的分析和确定，进行专机总体设计，专机的部件设计和施工设计。

Design Instruction
  This design is based on the mentor in factory many years of work experience of free design task. At the same time is also based on the plane,
Profit increase enterprises and have a single piece of large Numbers of high production efficiency.
   With the rapid development of modern industrial technology, especially as it in the rapid development of automation field, the plane
Research has become the most machine manufacturing industry an important direction of, in the modern industrial use, most of the machine design and
Manufacturing is done with large quantities of machine tools. Modern large industrial technology rapid development, and to reduce the cost of the realization of the plane,
Software support mechanism also makes the realization become more simple, therefore, the study of the plane design has very important theoretical significance
And the reality.
In the industrial development of the modernization of the tide, all kinds of mechanical design and manufacturing, chartered plane used more widely,more and more into productivity, and in this sense, the study of plane has an important practical significance. Plane is according to the processing need to general parts as the foundation, match with a few special parts of a kind of high efficient special machine tool. Plane is according to the series of standardized design of general parts and the shape of the parts on the processing and processing technology requirements of the special parts designComposition of the special machine tool. Due to the general parts have standardization and serialization, can according to need flexible configuration, so as to shorten the design and manufacture of cycle, therefore, chartered plane has the advantages of low cost and high efficiency, the large, mass production in getting it .A wide range of applications, and can be used to form an automatic production line.
  Special plane is a kind of special high automation technology and equipment, current, because it is still large quantities of high efficiency and mechanical products
High quality and efficiency of the production of the critical equipment, they have been widely used in automobiles, tractors, internal combustion engines and compressors xu Many industrial production field. Among them, especially in the automotive industry, is the largest user plane. Such as Volkswagen in the car factory
Germany engine factory, in mass production of machinery industry departments, the equipment is used in great quantities in the plane. Therefore,
The technical performance and special plane integrated automation level, to a great extent determine the industrial department of these products production efficiency,
The product quality and enterprise production organization structure, but also, to a great extent determine the enterprise product's competitiveness.
  Type B three tubes are to be used in plumbing pipes of the important component, provide hot water for more than a diversion channel. In order to improve the processing the three the M8 threaded hole efficiency and quality, adopt the special plane for processing, machine tool design three axis and processing three the M8 threaded hole, this can make the distance between the threaded hole get accurate assurance, use special plane can make with processing efficiency improving times, and greatly thread quality, reduce operating worker's working intensity.
  This design work will design a vertical four shaft tapping plane. Therefore, the purpose is to make the machine design of simple structure,easy to use, high efficiency and good quality. Thus to select the best method to determine the appropriate concentration degree machine working procedure,A reasonable choice of plane general parts, the right type machine configuration, a reasonable choice cutting amount, and the design high the efficiency of the tool, cutting tool and spindle box is the main content of design. The specific job is to make the processing plan into line machine structure project analysis and determined, the plane on the overall design, plane design and construction parts design.
