Abstract: A freezing support device and method for a large thin-walled part, which belongs to the technical field of machining support. The present invention realizes freezing support for a large thin-walled part by a freezing system and an auxiliary system, wherein the freezing system comprises a heating source, a freezing source, flexible films, support plates, etc., and the auxiliary system comprises a rotating device, a moving plate and guide rails. The present invention utilizes ice with a certain thickness formed on a support side of a machining area and supports a workpiece through the ice, and the ice is always used as a support along with the progress of machining to have an effect of follow-up support. The present invention simplifies a support structure, and has the advantages of low cost, no contamination to a machine tool, and convenient use; plays a function of clamping the workpiece.
