设计简介
摘要
随着我国经济的发展，工业生产在国民经济中占据着尤为重要的地位。钻床作为机械制造和修配工厂必不可少的设备，具有广泛用途的通用性机床，可对零件进行钻孔，扩孔，铰孔，锪平面和攻螺纹等加工。同时钻床又存在着加工精度，加工效率不高等缺陷。在我国，组合钻床发展已有28年的历史，其科研和生产都具有相当的基础，应用也已深入到很多行业。是当前机械制造业实现产品更新，进行技术改造，提高生产效率和高速发展必不可少的设备之一。它的特征是高效、高质、经济实用，因而被广泛应用于工程机械、交通、能源、军工、轻工、家电等行业。我国传统的组合钻床及组合机床自动线主要采用机、电、气、液压控制，它的加工对象主要是生产批量比较大的大中型箱体类和轴类零件，完成钻孔、扩孔、铰孔，加工各种螺纹、镗孔、在孔内镗各种形状槽等。 本文设计的六孔卧式组合钻床，作为一种专用机床其生产效率高，加工精度高，特别适合于加工一些有多个孔并对孔的位置精度要求高的工件。

Abstract
With the development of our national economy, industrial production in the national economy occupy a very important position. Drilling machinery manufacturing and repair factory as essential equipment, with wide application of universal machine tool, the parts for drilling, reaming, reaming, reaming and tapping processing plane. While drilling has the processing precision, processing efficiency is not high. In our country, the combination drilling machine development has 28 years of history, its scientific research and production, have a considerable foundation, application also penetrated into many industries. Is the machinery manufacturing industry to realize product updates, technical innovation, improve the production efficiency and the rapid development of one of the essential equipment. It is characterized by high efficiency, high quality, economical and practical, so it has been widely used in engineering machinery, transportation, energy, industry, light industry, household appliances industry. Our traditional combination drilling machine and the combined machine tool automatic line mainly uses the machine, electricity, gas, hydraulic control, its processing object is mainly the production lot larger-and medium-bold type and shaft parts, finished drilling, reaming, reaming, the processing of thread, boring, in various shapes such as Kong Neitang tank.
This design six-hole horizontal combination drilling machine, as a kind of special machine for its high production efficiency, high processing precision, particularly suitable for processing with a plurality of holes and the position precision of the holes demanding workpiece.
Key words: drilling machine; tin; horizontal; combination drilling machine; precision machining; bed; rail; spindle box
