摘 要
本次设计主要是针对PASSAT迈腾汽车的后保险杠的装配线的设计，本次装配线分为后保险杠的压装机和装配机两部设备。其中压装机进行的工作内容是导流板的压装和拖钩盖板的安装，而装饰条的安装是手工装配的。而装配机的工作内容是对侧面导向支架、隔热板和U型夹的安装。本次设计的框架是用标准型材构成，并且一整套连接和支架结构都用此配套设备。
设计过程是由给定的后保险杠以及其定位元件（非金属材料）为基准在运用CATIA三维建模知识进行设计，在装配图条件下直接生成实体模型.压装机的设计比较复杂,除了整体框架结构,还要有线性导轨支撑的定位元件框架整体结构和气动元件推动的压头来完成导流板的压装工序.设计完成后要通过对气缸的压力数据记录而对后保险杠压装机的门字梁进行受力校核,看主梁是否满足强度和刚度的要求.最后对某一压头的加工进行分析并记录加工程序^【1】.

ABSTRACT
This design is mainly directed against PASSAT Mai Tang Bumper cars after the assembly line design,The assembly line is the pressure after bumper assembly plants and two aircraft equipment.Pressure which installed the important work is the pressure plate,and trailers loaded hook decked installation,and decoration of the installation of manual assembly.And the assembly of the contents of the work-oriented aspect of the stent installation and insulation panels and the U-shaped clip installation.The framework is designed with standard profile form,and a set of connectivity and support structure using this set of equipment.
Design process is given after the Bumper and its positioning devices (non-metallic materials) as a benchmark in the use of CATIA 3D Modeling knowledge for the design,assembly drawings generated directly under the conditions of solid model.Pressure installed more complicated the design,Apart from the overall framework structure,Linear guide will be supported by positioning components and the overall structure of the framework of pneumatic components-driven pressure around the plate to complete the installation of pressure sequence.Upon completion of design right through to the cylinder pressure data records Bumper pressure right after the doors installed word beam force Verification,Girder see whether they meet strength and stiffness requirements.Finally,the pressure of a first analysis of the processing and recording processes
