Quenching treatment clamp

The invention relates to the technical field of heat treatment deformation prevention, in particular to a quenching treatment clamp. The quenching treatment clamp comprises exhaust pipelines, telescopic pipes, movable plug pins, an external pressure steel belt, a hoisting structure, a double-layer frame, a bottom plate, spherical surface inner supports, locking nuts and adjusting lead screws. Whena product is subjected to solid solution quenching, air in a closed cavity needs to be rapidly exhausted, rapid water entry of the product is guaranteed, thermal stress concentration caused by the temperature difference of different positions of the product due to slow exhaust is reduced, and the product can rapidly enter water through the design. Due to the fact that the diameter of the productis too large and the wall thickness is small, an inner support anti-deformation structure is designed, in other words, adjustable ejector blocks are evenly distributed in the circumferential directionof the product, constraint
