【摘要】：焊接是汽车制造技术中的一项关键技术,焊接的质量直接影响着整车的制造品质。高精度、柔性化、智能化的焊接夹具在汽车的焊接生产中占有重要的地位。本文所研究的是某型轻型车主焊地板线夹具,是轻型车地板焊装的重要组成部分。以国内外汽车焊装夹具的发展与应用,与相关技术的国内外研究现状作为背景。对轻型车地板工艺规划和工艺分配等进行了分析与设计,确定了焊接工位的布局和焊点的位置分布,以及各工位的焊钳类型。以CATIA设计软件为三维设计平台,对焊装夹具进行结构设计。应用ROBCAD仿真软件,对轻型车地板总成机器人焊接工位,进行焊接过程的模拟仿真,对仿真结果进行分析,验证焊接的合理性。实践应用表明,焊接夹具的结构能够满足轻型车地板焊接时对焊件的定位夹紧;焊接操作用时,可以达到生产节拍要求。
[Abstract]:Welding is a key technology in automobile manufacturing technology. The quality of welding directly affects the manufacturing quality of the whole vehicle. High precision, flexible and intelligent welding fixture plays an important role in automobile welding production. In this paper, a light owner welding floor wire fixture is studied, which is an important part of light vehicle floor welding. Based on the development and application of automobile welding fixture at home and abroad, and the research status quo of related technology at home and abroad. This paper analyzes and designs the process planning and process distribution of the floor of light truck, and determines the layout of welding stations and the distribution of solder joints, as well as the types of welding forceps in each position. The structure of welding fixture was designed with CATIA software as three-dimensional design platform. Using ROBCAD simulation software, the welding process of the floor assembly robot of light vehicle is simulated and the simulation results are analyzed to verify the rationality of the welding. The practical application shows that the structure of the welding fixture can meet the requirements of the production rhythm when welding the light car floor.
