内容简介：

摘 要我的毕业设计是基于现有设备的改造或者说是在其基础上的重新设计。气动夹紧装置从产生到现在，大概分为三个阶段：第一阶段主要表现在夹紧装置与人的结合上，这是夹紧装置主要作为人的单纯的辅助工具，是加工过程加速和趋于完善；第二阶段，夹紧装置成为人与机床之间的桥梁。加紧装置的机能发生变化，它主要用于工件的定位和夹紧。人们越来越认识到，夹紧装置与操作人员改进工作及机床性能的提高有着密切的关系以及作用。所以对夹紧装置引起了很大的重视；第三阶段夹紧装置与机床的结合，夹紧装置作为机床的一部分，成为机械加工中不可缺少的工艺设备。随着现代机械的加工越来越多的使用数控机床及其组合机床，如何提高产品的加工精度、提高劳动生产率、降低工人的劳动强度，这是我们必须考虑的问题，这就使得多气缸气动夹紧装置的设计和生产应运而生。但是随着机械工业的迅速发展，对产品的品种和生产率提出了越来越高的要求，特别像不规则零件的加工还处于落后阶段。所以在今后的发展中我们要大力推广多气缸气动夹紧装置。而我的设计的主要内容是一种阀体零件的检测装置中的多气缸气动夹紧装置。由于现有的设备存在着很多不足之处，所以在我的设计中要继承原来的主体设计，着重在那些欠缺的地方进行改进。在机床技术方面应该朝高速、高效、精密、复合、智能、环保方向发展的带动下，多气缸气动夹紧装置正在向着全能自动化快速发展。关 键 词 ：阀体；气动夹紧装置；重新设计Abstracts：My graduation design is based on the renovation of the existing equipmentor on the basis of the redesign. Pneumatic clamping device from produce to thepresent, roughly divided into three stages: the first phase mainly displays on theclamping device with a combination of people, this is the clamping device is mainlysimple auxiliary tool, as a person is to speed up processing and perfect; In the secondphase, the clamping device becomes the bridge between man and machine tool. Thefunction of the device is changed, and it is mainly used for the positioning andclamping of the workpiece. There is a growing recognition that the tightening devicehas a close relationship with the improvement of the operator and the performance ofmachine tools. So there is a lot of emphasis on the clamping device; The combinationof the clamping device and the machine tool, the clamping device as part of themachine tool, becomes the indispensable process equipment in machine processing.With modern mechanical processing more and more use of nc machine tools andcombination machine tools, how to improve the machining accuracy, improve laborproductivity, reduce the labor intensity of workers, this is we must consider thequestion, this makes the multiple cylinder design and production of pneumaticclamping device arises at the historic moment. But with the rapid development ofmachinery industry, the product variety and productivity, higher and higher demandsare proposed, especially like irregular parts processing is still in a backward stage. Soin the future development, we will vigorously promote the multi-cylinder pneumaticclamping device. The main content of my design is a multi-cylinder pneumaticclamping device in the body parts testing device. Because there are manyshortcomings of the existing equipment, so in my design to inherit the main body ofthe original design, mainly in areas that lack of improvement. In machine tooltechnology should be toward high speed, high efficiency and precision, composite,intelligent, environmental protection direction, multiple cylin
