摘    要

    在机械制造各行业的工艺过程中广泛应用着各种不同的，用以固定加工对象，使之占有正确位置，以便接受施工的一种工艺装备，统称为夹具。因此，无论是在机械加工，装配，检验，还是在焊接，热处理等冷，热工艺中，以及运输工作中都大量采用夹具。但在机械加工中应用最为广泛的是金属切削机床上使用的夹具，我们称其为机床夹具。它在保证产品优质，高产，低成本，充分发挥现有设备的潜力，以便工人掌握复杂或精密零件加工技术，以减轻繁重的体力劳动等诸方面起着巨大的作用。因此，机床夹具的设计和使用是促进生产迅速发展的重要工艺措施之一。为此，在本次毕业设计时，选择了机床夹具设计。
    本文主要围绕机床夹具设计为中心。用以铣正四棱台零件，首先通过参观实习让我们对夹具设计有了初步的了解，特别是对钻模夹具设计的了解更为深刻。然后，在导师的指导下，对夹具设计方案进行分析和选择。选定方案后。通过查阅相关夹具设计书籍和相关图例在夹具设计过程中，。在查阅了相关文献后完成外文翻译。参考相关资料完成夹具的总体设计。

ABSTRACT

In the machinery manufacturing industry the process is widely used in a variety of, to fix the processing object, so that possession of the correct position, to accept the construction a technology and equipment, collectively known as the fixture. Therefore, both in mechanical machining, assembly, inspection or in welding, heat treatment, such as cold, heat process, and transport adopt a large number of fixture. But in the mechanical machining most widely used is the metal cutting machine tool use jig, we call it the machine tool jig. It guarantees product quality, high yield, low cost, give full play to the potential of existing equipment to workers to master complicated or sophisticated parts processing technology, in order to reduce the heavy manual labor, and other aspects plays a huge role. Therefore, the design and use of machine tool fixture is one of the important technological measures to promote production rapid development.. To this end, in the graduation design, the choice of machine tool fixture design.
This paper mainly focuses on the design of machine tool fixture. With milling is a quadrangular prism parts. First of all, through the visit practice let us have the preliminary understanding to the fixture design, especially on the drill jig design understanding more profound. Then, under the guidance of the tutor, the fixture design scheme analysis and selection. After the selection of the program. The fixture design books and related consulting legend in fixture design,. After consulting the relevant documents, complete foreign language translation. Complete the overall design of the fixture with reference to the relevant data.
