High-temperature compression test clamp for special-shaped thin-wall plate-shaped structure

The invention discloses a high-temperature compression test clamp for a special-shaped thin-wall plate-shaped structure, relates to the technical field of aviation, aerospace and ship precision equipment, and aims to solve the problem that the compression clamp in the prior art does not consider the difficulty in centering of a special-shaped structural part and the use requirement of the special-shaped structural part in a high-temperature environment, so that the accuracy of a compression test is low, the clamp comprises an upper compression loading end five-face U-shaped groove, a lower fixing end five-face U-shaped groove and a positioning cushion block, and the upper compression loading end five-face U-shaped groove and the lower fixing end five-face U-shaped groove are cuboids with grooves formed in the middles; U-shaped leaning openings of the upper compression loading end five-face U-shaped groove and the lower fixing end five-face U-shaped groove are oppositely arranged, and the positioning cushion b
