摘要 焊接作为一种工艺手段，已经成为很重要的热处理加工技术。焊接技术是随着金属的应用出现的，金属焊接的方法有很多种，各种压焊方法的共同特点是在焊接过程中施加压力而不加填充材料。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. 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. On the basis of the whole shaft, bearings, couplings, such as stiffness, longevity requirements, integrated displacement requirements. we could determine the remaining components.
