摘要 随着全球经济的不断发展，人们生活水平日益提高，废弃的机电产品与日俱增，资源和能源的不足，已经成为制约社会发展的一个重要原因，人类与环境协调发展的任务更加突出，对再制造的需求也更为迫切。其中比较先进的技术当属激光再制造，所以对此技术展开研究非常有必要。本次毕业设计主要研究一套用于装夹存在线缺陷的钛合金薄板的夹具，这套夹具主要由夹具体、定位元件、夹紧装置等部分组成，并通过一系列工艺实验验证该套夹具的可行性。本论文首先简单介绍了再制造工程的背景以及夹具的定义，然后根据工作台的参数确定装置各零部件的尺寸，同时用UG软件进行三维建模，最后详细介绍基于此套夹具进行的一系列工艺实验，通过分析实验数据来判定夹具的可行性。

Laser remanufacturing process and fixture design of titanium alloy sheets with line defects
Abstract With the development of global economy and the improvement of people’s living standards, the amount of dumped electromechanical products has been increasing with each passing day. Shortage of resources and energy has become an important factor which restricts social development. As the task of coordinated development between man and environment has gained its significance, the demand for remanufacturing process is becoming more and more urgent. Therefore, it is very necessary to study laser remanufacturing, one of the most advanced technologies. This thesis mainly studies a set of fixtures which are used to clamp titanium alloy sheets with line defects. This set of fixtures mainly consists of clamp parts, locators, and clamping devices. And the feasibility of this set of fixtures will be verified through a series of experiments. In this thesis, the background of remanufacture engineering and the definition of fixture are firstly introduced. And then the sizes of various components of the device are determined according to the parameters of the working table. At the same time, the author uses UG, a modeling software, to offer a three dimensional model. At last, a series of experiments which are based on this set of fixtures are elaborated, and the feasibility of this set of fixtures is finally determined by the analysis of experimental data.
