毕业论文--气动焊接夹具的设计.docVIP

毕业设计 题 目 零件组焊气动夹具设计 零件组焊气动夹具设计 摘 要 本公司担任生产制造工作，本文研究是的枕梁部件的焊接夹具设计问题，要求使工件定位迅速，装夹方便、省力，减轻了焊件装配定位和夹紧时的繁重体力劳动。实现机械化，便于变位迅速，使焊接条件较差的空间位置焊缝变为焊接条件较好的平焊位置焊缝，劳动条件得改善，同时也有利于提高焊缝的质量。 枕梁部件主要是由钢板组焊而成，精度要求不高。本文主要设计的是组焊这套部件的专用夹具。由于这部件里面还有一个小的组件，所以需要设计两套夹具。南车集团和中兴轨道装备有限公司联合设计制造的火车内部饰件精度要求不高，主要由若干钢板组焊而成。本文的主要任务正是基于该内饰件的焊接工艺，开发两套专用夹具用于该内饰件和其中一个组件的焊接工作。 本文的设计内容，包括夹具的总体方案，定位方式，气动加紧部分，最后是夹具体的设计。因为是焊接夹具，有些部位需要转动，这里有用动变位器。因为对于焊接来说，焊两件的时候最好能在最有利的位置，即平焊，而变位器可以解决这一问题，将工件夹紧之后它可以绕着一轴旋转，方便焊接。 关键词：工装，夹具，气动，焊接 Parts welding pneumatic fixture design Abstract The responsibility of my company is manufacturing. The part of the train interior, designed by CSR, manufactured by my company。The purpose of this study is that with fixture, positioning quickly, easy clamping, effort, reduce the weldment assembly positioning and the clamping the heavy manual labor. its significance lies rapid deflection, and make the spatial location weld of poor conditions into a better position weld , improved working conditions, at the same time it help to improve the quality of the weld. The part accuracy is not high, mainly from welded steel plate group, In this paper, design, welding set of components dedicated folder with, there is also a small component of this parts, so it is necessary to design two sets of fixtures the following is designed The test included the overall scheme of the fixture, positioning the way, part of the heart and pneumatic stepping up, the last folder specific design. Because the welding fixture, some parts of the rotation, here useful dynamic deformation. For welding, welding two pieces is best can in the most advantageous position, i.e. flat, and the positioner can solve this problem, the workpiece clamping it can rotate around an axis of rotation, convenient welding.
