The invention discloses a flexible gantry structure which is characterized in that the gantry structure includes two symmetric-arrangement circular arc parts (1), the two circular arc parts (1) are fixedly connected through a plurality of uniformly-distributed connection rods (2), circular arc racks (3) and circular arc orbits (4) which are matched are also arranged in the facing directions of the two circular arc parts (1), the circular arc parts (1) are each composed of a plurality of circular arc components (5), a connection face (6) is arranged between each adjacent circular arc components (5) in a matching mode, keys (7) are arranged between the matched connection surfaces (6), a first pin shaft (8) parallel to the keys (7) and a second pin shaft (9) vertical to the first pin shaft (8) are arranged on the connection surfaces (6), and the matched connection surfaces (6) are fixedly connected through a plurality of bolts. The flexible gantry structure is simple in structure, clever in design, rational in layout, and suitable for processing different-curvature arc-shaped thin wall parts.
