摘要
本文主要介绍了钻孔夹具成组技术发展的现状、趋势，并结合本次设计涉及的夹具介绍了轴类成组钻孔夹具的原理、影响加工精度的因素和减少误差的方法、夹具制造过程中的精度，分析了国内及国外发达国家成组制造技术的现状和发展趋势，简单介绍了钻孔夹具的工作原理及组成，以成组技术为核心理念，根据结构形状和功能等对产品零件进行分类,然后把形状相似、尺寸相近、加工要素和安装方式相同的零件挑出来,形成所需要的成组工序组,按成组工艺统筹考虑夹具的设计方案进行夹具结构设计,最后对所设计的成组夹具进行定位误差分析。最后给出夹具的工程图样和三维构造图。本设计对夹具设计和成组技术的探索为今后从事成组夹具的设计奠定了基础，和可以借鉴的经验。

Abstract
This article mainly introduces the drill hole jig underwriter development's present situation, the tendency, and unified the jig which involved to introduce the axis class become the group drill hole jig's principle, the influence working accuracy factor and in the reduced error's method, the jig process of manufacture precision, has analyzed the home and the overseas developed country becomes the group technique of manufacture the present situation and the trend of development, introduced simply the drill hole jig's principle of work and the composition, take the underwriter as the core ideas, and so on carried on the classification according to the structure shape and the function to the product components, was similar the shape, the size was close, the processing essential factor and installed the way same components to select, forms becoming which neededThe group working procedure group, according to becomes the group craft overall plan to consider that jig's design proposal carries on the jig structural design, finally to Cheng who designs Zu the jig carries on the position error to analyze. Finally gives jig's engineering drawing and the three dimensional constructional drawing. This design will be engaged in the group jig's design to the jig design and the underwriter exploration for the present to lay the foundation, with experience which may use for reference.

Keywords：Drills a hole the jig Underwriter Axis class components Clamp
