摘要

 随着现代工业的高度发展和焊接技术的不断进步，焊接作为一种金属连接的工艺方法，在金属结构生产中已基本取代了铆钉连接工艺。焊接产品质量的好坏不仅取决于焊接工艺质量，与备料、装配等工序也有密切联系。因此，在整个焊接生产过程中，不论产品的质量要求和批量的大小，均应考虑采用生产工艺装备。其中，焊接滚轮架是借助于主动轮与工件间的摩擦力带动筒形工件旋转的焊接变位机械，其主要应用于筒形工件的装配与焊接。本文主要研究了以下内容：
 在已知筒形工件的重量与旋转转速的前提下，考虑到传动过程中存在的摩擦效率以及最终的输出功率，确定电动机型号。再以选定的转速为基础，求出传动装置的传动比，从而进一步确定选用减速器的传动形式、数量等。再根据总体上对轴、轴承、联轴器等的刚度、寿命要求、综合位移要求等，确定其余零部件。

Abstract

   With the high level of modern industrial development and the continuous advancement of welding technology, welding metal as a way to connect the technology in the production of metal structures has basically replaced the rivets connecting process. The quality of welding quality depends not only on the quality of welding technology, but also on  the preparation and assembly processes are closely linked. Hence, throughout the welding process, regardless of the quality of the product requirements and batch size,we should consider the use of production technology and equipment. Among them, the wheel frame is welding driving wheel with the workpiece by means of friction between the cylindrical workpiece driven welding positioner rotating machinery, mainly used in the cylindrical workpiece and welding assembly. This paper studys the following:
   Cylindrical workpiece in a known weight and rotation speed under the premise of the process of taking into account the transmission efficiency of the existence of friction and, ultimately, the output power to determine the motor type. Then selected based on speed, calculated the transmission gear ratio, so as to further determine the selection of the drive reducer form, quantity, and so on. On the basis of the whole shaft, bearings, couplings, such as stiffness, longevity requirements, integrated displacement requirements, etc., we could determine the remaining components.
 
Key words: welding; production process quality; welding wheel frame; cylindrical workpiece
