爬行式气电立焊机器人的磁吸附机构距离熔池较近,而且采用了磁悬浮铜滑块设计,考虑到温度对铁磁性的影响,研发中需要了解焊接温度场的分布状况。该文以Rykalin公式为基础,构建了气电立焊的温度场模型,采用Matlab7.0.4软件进行了数值计算和仿真,得到了焊接过程中的温度分布。研究表明,温度场对于爬行式气电立焊机器人的磁吸附机构基本没有影响,但是会直接影响到吸附铜滑块的设计,因此在计算悬浮磁块吸力的时候需要考虑温度系数。气电立焊温度场模型的建立为爬行式气电立焊机器人的磁吸附机构和磁悬浮铜滑块的设计提供了重要依据。
Climbing gas vertical welding robot magnetic adsorption mechanism closer to the pool, and the use of maglev copper slider design, taking into account the impact of temperature on ferromagnetism, the development needs to understand the welding temperature distribution. Based on the Rykalin formula, a temperature field model of gas-electric vertical welding is established. The numerical calculation and simulation are carried out by Matlab7.0.4 software, and the temperature distribution during welding is obtained. The research shows that the temperature field has no influence on the magnetic attraction mechanism of creeping aero-electric vertical welding robot, but it will directly affect the design of the adsorbed copper slide. Therefore, the temperature coefficient needs to be taken into account when calculating the suction force of the suspended magnet. The establishment of the temperature field model of gas-electric vertical welding provides an important basis for the design of the magnetic attraction mechanism and the maglev copper slider of the crawler-type gas welding robot.
