Flange circulation tray

The invention relates to the technical field of machinery, and provides a flange circulation tray. The flange circulation tray comprises a tray body and is characterized in that a tray body is provided with placing grooves used for placing and limiting three different flanges, and limiting bulges extending inwards are arranged at the bottoms of the placing grooves; each placing groove comprises afirst limiting groove group, a second limiting groove group and a third limiting groove group which are distributed in the circumferential direction, and the first limiting groove group, the second limiting groove group and the third limiting groove group are correspondingly placing areas of the three different flanges; and the first limiting groove set, the second limiting groove set and the third limiting groove set each comprise oppositely-arranged grooves, and the grooves serve as grooves used for being embedded into the opposite sides of the flanges and used for limiting the flanges in the circumferential directi
