Flexible butt joint equipment used for large-scale structural components

The invention provides flexible butt joint equipment used for large-scale structural components. The flexible butt joint equipment comprises an installing table, a plurality of sets of flexible adjusting supports and ball screws; the installing table is fixedly provided with a linear guideway, the multiple sets of flexible adjusting supports are located above the installing table and can move backand forth on the linear guideway, and the ball screws are arranged between the flexible adjusting supports and used for adjusting the distances between different sets of flexible adjusting supports so as to adjust the distances of the large-scale structural components. Compared with the prior art, a rigid and soft combined design idea is adopted, flexible adjustment of six freedom degrees including axial rotation, lifting, pitching, left-and-right motion, yawing and front-and-back motion of the large-scale structural components during butt joint can be achieved, high-accuracy butt joint of the large-scale structural
