1、 1 / 76 在现代机械制造业中，企业对专用机床有着广泛的需求。一般钻床劳 动强度大，专用性能低。生产率不高且不能保证精度；而多轴钻床操控方 便、省力、容易掌握，不易发生操作错误和故障，不仅能减少工人的劳动 强度，保证工人和钻床的安全，还能提高钻床的生产率。随着科学技术的 不断发展，专用钻床广泛应用于制造业。换句话说，专业化越强，企业越 能保证其产品质量。因此，专用机床的使用对企业竞争力的提升有着十分 重要的作用。 本设计主要解决了两大问题：多轴钻床的总体设计和夹具设计。为了 解决上述两大难题，首先分析了钻床总体设计，其中包括加工工艺分析、 钻床的钻削方式的设计等，从而解决了钻床的总体设计的

2、难题；在夹具设 计中采用合理的钻模板和定位装置对工件合理定位， 从而完成孔的扩铰工 序，解决了多轴钻床夹具设计中的另一难题，同时也讨论了多轴钻床的夹 具设计问题， 给出了夹具设计方案， 其中包括工件的定位分析， 误差分析， 从而使工件被加工后达到设计要求。 关键词：多轴钻床、总体设计、夹具 2 / 76 AbstractAbstract The special-purpose lathe is extensively demanded by enterprises in the modern mechanical manufacturing industry. The ordinary lat

3、he not only need a large number of man-power but also has a low performance. In addition, its productivity is low and the accuracy cant be ensured. However, the special-purpose lathe can not merely help enterprises to boost productivity great, saving a large number of manpower and material resource,

4、 still can improve the quality of the products. Meanwhile, it is easily maneuvered and guarantees workers safety. With the development of technology, multi-axles drilling machines are used in manufacturing frequently. Hence, the use of the special-purpose lathe plays an important part in the competi

5、tiveness of enterprises. This design mainly solved two big problems: the multi-axles drilling over-all design and fixture design. In order to solve these two problems, first of all, we analyzed drilling total design project, including processing technology analysis, drilling machine of the design of

6、 drilling way, which solved the problem of the overall design of drilling; Then we adopt the fixture design reasonable drill template and positioning device on the reasonable positioning, thus completing hole enlargement hinge process, solved the multi-axles drilling fixture design of another problem, also discusses the multi-axles drilling fixture design problem, this paper presents fixture design scheme, including the workplace positioning analysis, thus make error analysis is processed 3 /
