毕业论文 题目名称： 车门前围内板夹具设计 学生姓名： 学 号： 二级学院（系）/专业： 机电一体化 班 级： 机电1331 指导教师： 2016年5月28日 摘 要 焊装工艺是依维柯制造三大工艺之一，在依维柯的焊装车间，主要生产车身，其中，焊装夹具起到至关重要的地位，它的精密的制造影响这汽车的生产品质和汽车的生产速度。 在依维柯的二车身厂，每个工位都有一到两个夹具，夹具设备影响着生产。就拿车门工位举例，车门质量影响整车的制造。所以想要合格的车门，必须用合格的夹具。 本课题主要讲述了车身焊装技术，车门内板焊装设备。然后围绕车门前围10工位进行夹具设计，根据车门设计要求，进行防撞杆，车门内板和门窗加强板设计。依照车门内板工艺，进行夹具基板，安装板，连接板，定位元件，夹紧机构，旋转机构，正确选配气缸，L型板和定位销的总体设计。最后进行压转臂张开角和气缸夹紧力的计算。 关键词: 车门内板 夹具设计 夹紧机构 Abstract The welding process is Iveco manufacturing technology in the welding workshop of Iveco, mainly the production of car body, wherein, the welding fixture to critical position, its precision manufacturing of the car production quality and car production speed. In Yi Weike's two body factory, each station has one to two fixtures, the clamp equipment affects the production. Take the example of the door station, the quality of the car, the impact of vehicle manufacturing. So you want to pass the door, you must use a qualified fixture. This paper mainly describes the welding technology, welding equipment inside the door plate. Then around the door of the 10 station to carry out the fixture design, according to the design requirements of the door, to carry out the bumper, door inner plate and doors and windows to strengthen the board design. In accordance with the inner door panel process, the substrate holder, mounting plate, connecting plate, positioning element, clamping mechanism, rotating mechanism, a cylinder for correct selection, l plate and a positioning pin of the overall design. Finally, the calculation of the opening angle and the clamping force of the cylinder is carried out. Keywords: Door inner； plate clamp design； clamping mechanism 1 绪 论 2 1.1汽车焊装夹具市场分析 2 1.2国内外汽车焊装夹具的成长 3 1.4本课题设计要求和内容 3 2 汽车车身焊装技术 5 2.1 白车身的概念 5 2.2 车身尺寸偏差因素 6 2.3车身夹具工艺流程 6 2.3 焊接流程图 7 3 车门内板焊接
