摘 要焊接领域机械化发展和自动化发展十分快速，进而产生了焊接翻转机设备，已成为制造业中不可或缺的一种设备。其能够利用回转运动方式和翻转运动方式，把公交翻转到规范化的焊接部位展开焊接工作，提升了焊接水平和成效，还减少了这些工人所面临的劳动强度。本文设计了一台最大负载可承受2吨的焊接翻转机，有两个自由度，实现工件的回转和倾斜运动，使工件处于平角或“船形”焊接角度的位置。本文对传动装置和机架的设计进行详细的描述，特别强调了传动装置的设计。本次设计是根据预定的载荷和要求的确定设备所需要的电机类型，在此基础上设计了蜗轮蜗杆和齿轮的传动方式，并设计了相应轴的尺寸结构和配件型号，对一些外购件也进行了选择。最后使用CAD软件绘制相关的零件图、装配图。76187

Design of turning platform for Welding box

Abstract A necessary for the development of welding mechanization and automation development is very rapid, and then produce the reverse welding machine equipment, has become the manufacturing equipment。 It can make use of the rotary motion and turning motion, the bus turned to standardization of welding parts expand welding work, enhance the level of welding and effectiveness, but also reduce the workers faced labor intensity。 This paper designs a maximum load can withstand two tons of reverse welding machine, there are two degrees of freedom, the realization of workpiece rotary and tilting motion, so that the workpiece in the boxer or boat shaped welding angle position。 In this paper, the driving device and the frame design detailed description of The, with particular emphasis on the design of the transmission device。 The design is according to the predetermined load and required equipment and the required motor type identification, based on the design with worm and worm gear transmission, and design the corresponding axis of the structure and the size of the parts models, on some of the purchased parts have also been selected。 Finally the use of CAD software draw the parts diagram, assembly drawing。

There are 18 figures, 11 tables and 34 references in this paper。
