毕业设计（论文）-焊接转位装置的转角控制装置设计.doc

襄 樊 学 院 毕业设计论文年 月日摘 要 在我国，焊接变位机已成为制造业的一种不可缺少的设备，在焊接领域把他划为焊接辅机。近十年来，这一产品在我国工程机械行业，有了较大的发展，并获得了广泛的应用。使用焊接变位机械可缩短焊接辅助时间，提高劳动生产率，减轻工人劳动强度，保证和改善焊接质量，并可充分发挥各种焊接方法的效能。常用的人工焊接变位机基本型式有：伸臂式、倾翻回转式和双立柱单回转式等。由于受到回转自由度的限制，这几种变位机均不能实现被焊工件在空间内的任意旋转，不能使各类焊缝转动到所需要的最佳位置。以前我厂也从各地引进多种焊接变位机，但现场使用都不方便从而被淘汰，投资高浪费大。为开发适宜的变位机，我们经过多年的工作实践，调研分析，主要思路启发于从国外引进的结构件焊接机器人。焊接机器人上配备的焊接变位机的型式先进，适合国内工程机械行业结构件的焊接。根据现场使用经验，现分析介绍焊接变位机选型及常用几种变位机的形式等。关键词：The Design Of Manual Welding Shifts Machine Abstract Welding positioner has become an indispensable device of manufacturing field in our country. It is divided into Auxiliary machinery. This product has gained lots of progress and been access to a wide range of applications in Construction machinery field last decade. It can not only reduce auxiliary time in welding, lout also improve labor productivity. The welding positioner can assure and improve product quality, and make the most of performance of various welding methods. Manual welding positioner is currently a large number of welding machinery products, which by some mechanical drive mechanism used to achieve the welding of the work piece rotation, tilt, making the welding operation faster and more convenient, improve work efficiency. In this design, the reference design data and related information, first select the institutions and the transmission mode to determine the body parts of the transmission power, torque and the strength calculation and verification to ensure the rationality of institutions so that the equipment can be designed in a given period of normal work; and then connect the various agencies designed to draw the structure diagram; The final design details, to draw the total picture, to ensure product manufacturability, ease of scale production. The design of the main content is a tilt mechanism, using the worm body, to reduce the size and achieve self-locking transmission. The entire organization is simple, reliable, easy to operate Keywords: manual type welding displacements m
