The most common application of welding robot are in two main ways, spot welding and arc welding. The welding robot we are talking about is actually industrial robots which are doing the work in the welding tasks instead of welding production welder. Some of this welding robot is specially designed for welding while most of them are actually a common industrial robot fitted with a welding tool. In multi-task environment, a robot can even complete many kinds of work including the grasp of welding, handling, installation, welding, unloading and other tasks,. Therefore, in a sense, the history of the development of industrial robots is the history of the development of welding robot. It is well known that the welding processing on one hand requires on skilled operational skills, rich practical experience and stable level of welding; on the other hand, welding is a work with poor working conditions, dust, and heat radiation and high-risk. The emergence of industrial robots first makes people naturally think of using it to replace the manual welding to reduce labor intensity. But also it ensures the welding quality and enhances the efficiency of welding. The robot I designed is a DOF arc welding robot. The design statement mainly include design of robots drive system and the its composition, the choice of motor, design of bevel gear and verification, the principle of harmonic reducer and its choice, wrist Check the Department of rotational axis, the choice of rolling bearings and its checking and so on.KEY WORDS welding robot; profile belt transmission; harmonic reducer; 5-DOF 目錄中文摘要 英文摘要 目錄 前言 1 1 緒論 3 2 畢業(yè)設計基本思路 4 2.1總體所涉及思路及內(nèi)容 5 2.2設計傳動方案 5 3 焊接機器人腰部與大部設計 7 3.1 腰部結(jié)構(gòu)設計 7 3.1.1 電動機的選擇 7 3.1.2 諧波減速器介紹及選擇 8 3.1.3 軸的設計與校核 10 3.1.4 軸承的設計計算與核 113.1.5 齒輪設計計算與校核 123.2 大臂結(jié)構(gòu)設計 153.2.1 電動機的選擇 153.2.2 諧波減速器的選擇 15 3.2.3 軸的設計與校核 164總 18參考文獻 19致謝 202
