Fuel cell graphite plate machining and clamping device

The utility model relates to a clamping device for processing a graphite plate of a fuel cell. The clamping device comprises a base and a cylinder clamping device arranged on the base, the base comprises a vacuum suction cup located in the center and an installation base arranged around the vacuum suction cup. A plurality of T-shaped grooves are formed in the surface of the mounting base in the circumferential direction of the vacuum suction cup. The air cylinder clamping device comprises a rotating air cylinder, an air cylinder cantilever, an air cylinder fixing base and a T-shaped block matched with the T-shaped groove. The rotating air cylinder is installed on the T-shaped block through the air cylinder fixing base, the T-shaped block is arranged in the T-shaped groove, one end of the air cylinder cantilever is connected to a rotating shaft of the rotating air cylinder, and the other end of the air cylinder cantilever rotates along with the rotating shaft of the rotating air cylinder so as to abut against
