Abstract:

Pneumatic resistance spot welding tongs have been widely used in Welding process of automobile by the major automobile manufacturers. Known for traits such as pollutant-free, pressure stability, and response agility, PRSWT has gradually replaced the usual domestic the hydraulic pliers, improved the sluggishness of Hydraulic transmission and thus satisfies the welding cycle demand. In this Final year Project , designer has used the high-level programming language developed by Microsoft Corp——C#(also called C SHARP) and made secondary development on SolidWorks with the help of OLE(=Object linking and embedding technology) and COM(=Component object model technology) provided by SolidWorks, which completed the parametric design of the Pneumatic resistance spot welding parts — Electrode arm and electrode rod and the create task of 3D Part Library of Resistance spot welding tongs, which enables the designers to automatically generate the Electrode arms and electrode rod parts corresponding to different types according to the shape and size of the object to be processed with greater efficiency.

课题的背景及来源

随着金属的出现及其广泛的应用，焊接技术也随之不断的发展着。时至今日，电阻点焊作为焊接技术中重要的一支，已被广泛的运用于航天航空、能源、电子和车辆等高科技领域上，并承接了世界总焊接量的1/3，且呈逐年上升势态。例如：汽车驾驶室、汽车车身、飞机机翼、航空发电机扰流器、建筑用钢筋网、家具薄板、电冰箱等等都是以电阻点焊钳作为点焊工具而加工出来的。气动电阻点焊钳更是作为一项不可或缺的焊接工具已经被各大汽车制造厂商广泛运用于汽车焊接工艺中。它以无污染、压力稳定、动作敏捷等优点逐步替代了国内常见的液压传动焊钳，改变了液压传动滞缓的现象，从而达到了焊接循环的要求。因此，气动点焊钳生产的国产化对于国内汽车制造业的发展是非常有必要的。而本次课题电阻点焊钳零件三维图库基于C#的SolidWorks二次开发能够加速其开发过程对其国产化进程有推动作用。

在我国，目前CAD市场上使用较多的三维CAD软件有：SolidWorks、UG、MDT、Pro/E等。其中美国SolidWorks公司开发的三维计算机辅助设计

C#(读作“C SHARP”)如名字一样，简单且功能强大类型安全，完全面向对象。C#凭借在许多方面的创新，在保持C语言风格的表现力和雅致特征的同时，实现了应用程序的快速开发。Visual C#是微软公司

汽车用电阻点焊钳主要由钳体、电极臂、气缸等部分组成。其
