【摘要】 板式换热器是由一系列具有一定波纹形状的金属片叠装而成的一种高效换热器，应用广泛。为解决实际焊接过程中人工焊接生产效率低、劳动强度大及生产成本高等问题，提出了一种随动式三轴联动柔性快速夹紧方法和焊接夹紧装置设计方案，其中随动柔性夹紧结构有效解决了板片组不规则变形导致夹紧效果不理想这一问题。采用SolidWorks软件完成了夹紧装置的设计，采用Ansys软件对关键零部件进行了静力学仿真分析，对部分结构进行了设计优化，有效避免了运动干涉和零件失效等问题的发生。样机试验表明：随动式焊接夹紧装置夹紧间隙小、焊接生产效率高和定位速度快，可协助工人或者焊接机器人进行快速定位夹紧焊接，对比人工夹紧焊接工作效率提升1倍以上。更多还原

【Abstract】 The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with corrugated shapes, which is widely used in various projects. Since manual clamping-welding suffers low production efficiency, high labor intensity and high production cost in the welding process, in this article both a follow-up three-axis linkage flexible fast clamping method and a design scheme of the welding clamping device are proposed. The follow-up flexible clamping structure effectively addresses the irregular deformation of the plate group, and thus the clamping effect is better. The SolidWorks software is used to design the clamping device. The Ansys software is used to conduct the static simulation analysis on the key parts. Some structures are optimized, which effectively avoids motion interference and part failure. The prototype test shows that the follow-up welding-clamping device has a small clamping gap, high welding efficiency and fast positioning speed. It can assist workers or welding robots to quickly locate, clamp and weld; the efficiency has more than doubled compared with that of manual clamping-welding.更多还原
