新型搅拌摩擦焊夹具设计

Design of New Clamp for Friction Stir Welding

在搅拌摩擦焊过程中,待焊工件的装夹对焊接质量起着至关重要的作用,常规钻铣床-夹紧块的装夹方式会使工件受力不均,同时也会占用大量的装夹时间,影响焊接效率。设计一种新型夹具,装配在搅拌摩擦焊设备的工作台上,能够显著地减少焊接工件的装夹时间,使工件受力均匀,保证焊接质量,提高焊接效率,为操作人员提供更多的便利。结果表明:所设计的夹具有良好的夹紧效果,为搅拌摩擦焊的夹具选择提供参考。

In the process of friction stir welding,the clamping of workpieces to be welded plays a crucial role in the quality of welding.The clamping mode of conventional drilling-milling machine-bolt platen will make the workpieces uneven force,and also occupy a lot of clamping time,affecting the welding efficiency.Designed a new type of clamp,assembled on the work table of friction stir welding equipment,can significantly reduce the clamping time of welding parts,make the workpiece uniform force,ensure the welding quality,improve the welding efficiency,and provide more convenience for operators.The results show that the designed clamp has a good clamping effect,which provides reference for the clamp selection of friction stir welding.
