摘要：

针对焊接精度要求不高的焊接机器人应用场合，设计出一种成本较低、位置控制精度较好的翻转式焊接工作台，以满足中低端产品的焊接工艺要求。在该翻转式焊接工作台中，采用气动马达作动力输出，蜗轮蜗杆大传动比传动系统作高精度分度装置，光电编码器作位置信息获取装置，并通过闭环控制实现高精度翻转运动。仿真结果表明，该焊接工作台最高转速达到14 r/min，能够满足大多数产品的焊接需求。设计的焊接机器人翻转工作台为中低端焊接产品提供了一种经济、有效的焊接机器人应用方案，对降低焊接机器人的应用成本、提高焊接生产效率具有重要意义。

Abstract:

A turnover platform for welding robot was designed for the application of welding robot with lower accuracy requirement, which was of low cost and higher position accuracy. In this turnover platform, the pneumatic motor was used as the power output, and the indexing mechanism with high accuracy was the transmission system with high transmitting ratio based on worm and wheel. The position information was acquired by using the photoelectric encoder, and the turnover motion with high accuracy was realized through the closed-loop controller. Simulation results showed that the maximum speed of the welding platform approached 14 r/min, and the platform could meet the requirements of most welding products. Such a turnover platform can offer the application program of the welding robot with low cost for the middle and low level products, and reduce the cost of welding robot and improve welding productivity.
