The invention discloses an automatic center positioning mechanism for a large-diameter pipe fitting. The automatic center positioning mechanism for the large-diameter pipe fitting comprises a support, an electric motor fixed on the support, a first feed screw connected with the electric motor through a second coupling, a second feed screw parallel to the first feed screw and a first coupling connected with the left and the right end of the first feed screw. The automatic center positioning mechanism for the large-diameter pipe fitting further comprises a first guide rod, a second guide rod and a workbench perpendicular to the first guide rod and the second guide rod. The lower end of the first guide rod and lower end of the second guide rod are each provided with two sliding seats. The first feed screw and the second feed screw are each connected with the two sliding seats. The workbench is provided with a sliding track. A scale is arranged on the workbench outside the sliding track, and the length of the scale is equal to the length of the sliding track. Two symmetrical arc-shaped positioning blocks are arranged on the sliding track. The two arc-shaped positioning blocks are fixedly connected with the first guide rod and the second guide rod respectively. According to the automatic center positioning mechanism, the moving stability is increased, the operation is simple and firm, the size of the inner diameter of the pipe fitting is convenient to read, and the positioning is accurate.
