摘要

根据铝合金复杂厚壁结构件产品对空间三维曲线搅拌摩擦焊技术的迫切需求，结合传统搅拌摩擦焊机头机构灵活性较差，仅能完成平面内二维直线焊缝的焊接的缺点，以三维并联搅拌摩擦焊机头为研究对象，将正交并联机构在精度、高刚性、承载能力及灵活性等多方面的优点与搅拌摩擦焊技术相结合，应用设计、计算、仿真手段，开发的高刚性三维并联搅拌摩擦焊机头具有极为重要的科学意义及工程实用价值。

Abstract

According to the urgent demand of aluminum alloy complex thick wall structural parts for spatial three-dimensional curve friction stir welding technology, combined with the disadvantage that the traditional friction stir welding head mechanism has poor flexibility and can only complete the welding of two-dimensional linear welds in the plane, this paper takes the three-dimensional parallel friction stir welding head as the research object, and combines the orthogonal parallel mechanism with Combining the advantages of load-bearing capacity and flexibility with friction stir welding technology, and applying the means of design, calculation and simulation, the developed high rigid three-dimensional parallel friction stir welding head has extremely important scientific significance and engineering practical value.
