In practice, the center sill assembly P (a1) generally includes a center sill web, a center sill diaphragm, a center sill lower cover, and a center sill upper cover.
The center sill assembly unit comprises a center sill positioning mechanism 21 and a center sill assembly clamping mechanism 22. In the middle beam assembling stage, the middle beam positioning mechanism 21 is used for positioning and holding the middle beam assembly P (a1), so that different middle beam assemblies P (a1) are positioned at the correct positions on the base 1; the centre sill assembly clamping mechanism 22 is detachably arranged on the base 1 or the centre sill positioning mechanism 21 and is used for clamping the centre sill assembly P (a1), so that the centre sill assembly P (a1) can still be kept at the correct position under the action of external force. In the underframe assembling stage, the centre sill positioning mechanism 21 is used for positioning and holding the centre sill p (a); the center sill assembly clamp mechanism 22 is removed prior to undercarriage assembly to avoid interference with the clamping of the center sill p (a).
Exemplarily, the number of the center sill assembly units is equal to that of the center sills p (a), and the positions of the center sills p (a) correspond to one another.
