Cooling fin overturning and combining mechanism

The invention discloses a cooling fin overturning and combining mechanism, and belongs to the technical field of machining equipment. The device mainly comprises a support, a rotating cage and sheet combining plate sets, the support is supported on the ground, the rotating cage is rotationally matched on the support, each sheet combining plate set comprises a bearing table and an overturning driver, the bearing tables are rotationally matched on the rotating cage, the rotating cage is provided with at least two sheet combining plate sets, and the bearing tables of the multiple sheet combining plate sets are arranged in a circumferential array in the circumferential direction of the rotating cage. The overturning driver is used for driving the bearing table to overturn on the rotating cage, when the bearing table rotates to a first position away from the axis of the rotating cage, the rotating cage rotates to enable the bearing table to be in a horizontal state, and when the overturning driver drives the beari
