The invention discloses a temperature control device and method of a clamp for a high-temperature environment vibration test of an aircraft component. The device comprises the clamp arranged on a vibration table and used for clamping the aircraft component to be tested, a plurality of temperature sensors arranged on the clamp and a cooling water system used for cooling the clamp. The method comprises the following steps: 1, clamping a to-be-tested aircraft component; secondly, a cooling water system is connected to the clamp; 3, mounting a heating device; and 4, adjusting the temperature of the clamp in the vibration test process. According to the invention, the annular cooling water channel is arranged in the clamp, and the flow of the cooling water entering the cooling water channel of the clamp is adjusted by adjusting the opening degree of the cooling water flow rate adjusting valve according to the actually measured temperature of the clamp, so that the cooling system can automatically cool the clamp along with the loading process of the test temperature; and therefore, the temperature of the clamp can be effectively and stably kept in a controllable range, and the temperature of the clamp can be effectively controlled.
