Accurate measurement device and method for antenna packaging foaming expansion force

The invention provides a device and a method for accurately measuring the foaming expansion force of antenna packaging, belongs to the technical field of antenna packaging and cementing, and solves the problem that the foaming expansion force cannot be measured in the existing scheme. The device comprises a sample loading assembly, a moving assembly, a heating assembly and a measuring assembly, a cavity for accommodating polystyrene foam is arranged in the sample loading assembly, the height of the cavity is telescopically changed along the axis direction under the action of the movable end of the sample loading assembly, and the cavity is sealed by the sample loading assembly; the moving assemblies are respectively positioned above and below the sample loading assembly and are used for clamping the sample loading assembly and moving up and down along with the expansion and contraction of the movable end of the sample loading assembly; the sample loading assembly, the moving assembly and the measuring assembl
