多孔涡轮的夹具设计(含CAD夹具图)(任务书,设计说明书11500字,CAD图纸1张)
摘要
    机械制造技术不仅是衡量一个国家科技发展水平的重要标志，也是国际间科技竞争的重点。我国正处于经济发展的关键时期，制造技术是我们的薄弱环节。PC机进入数控领域，极大的促进了数控技术的发展，也为我国在数控生产领域赶超发达国家提供了机遇。跟上发展先进数控制造技术的世界潮流，将其放在战略优先地位，并以足够的力度予以实施，尽快缩小与发达国家的差距，在激烈的市场竞争中立于不败之地。同时，数控加工技术的发展孕育产生大量的数控专业技术人才，进而推动我国现代机械制造业进一步走向繁荣。
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。

Abstract
Mechanical manufacturing technology is not only the important sign of weighing a national science and technology development level, is the focus of international technological competition. China is in a critical period of economic development, manufacturing technology is our weak link. PC access control field, has greatly promoted the development of NC technology, it provides the opportunity for China to overtake the developed countries in the field of CNC production. Keep up with the development of advanced NC manufacturing technology trends in the world, will be the priority strategy, and with enough strength to be implemented, narrow the gap with developed countries as soon as possible, remain invincible in the fierce competition in the market. At the same time, the development of NC machining technology has produced a lot of CNC professional and technical personnel, and promote China's modern machinery manufacturing industry further prosperity.

In the process of machinery manufacturing industries in a wide variety of applications, for processing a fixed object, so that possession of the correct position, to receive a construction techniques and equipment, collectively referred to as the fixture. Therefore, whether in the machinery processing, assembly, testing, or in welding, heat treatment and cold, heat process, and transport are a lot of work in a fixture. But in machining is the most widely used fixture using metal cutting machine tool, we called for the machine tool fixture. It guarantees product quality, high yield, low cost, and give full play to the potential of existing equipment, so that workers have complicated or precision parts processing technology, to reduce the heavy manual labor and other aspects play a huge role. Therefore, the design and use of machine tool fixture is one of the important measures to promote the rapid development of the technology of production.
This article focuses on the pipe joint and fixture design center. The first joint, let us have a basic understanding of the design and mechanical processing clamp through processing, especially the NC machining and parts of fixture design knowledge more profound. Then, under the guidance of tutor, to analyze and select parts processing design and fixture design. The selected scheme,. Through the relevant parts and fixture design books and related legend refer to in the process of machining parts, after having consulted the related literature, the overall design reference to relevant information to complete parts.
