Semi-automatic pre-tuning device suitable for multi-cavity-cell ellipsoidal superconducting cavity

The invention relates to a semi-automatic pre-tuning device suitable for a multi-cavity-cell ellipsoidal superconducting cavity, and the device is characterized in that a supporting assembly is provided with a supporting seat which is slidably installed and fixed on a main body frame, and the two ends of the superconducting cavity are installed and fixed through the supporting seat; the pulling and pressing driving assembly is connected with the pulling and pressing plate assembly so as to act on the pulling and pressing plate assembly and stretch and compress an acceleration cavity cell of the superconducting cavity; the lifting mechanism is fixed on the main body frame and is connected with the tension and compression module so as to move the tension and compression module to each acceleration cavity cell acting on the superconducting cavity; the winding driving assembly passes through a thin wire of the superconducting cavity and uniformly moves along the axis of a cavity body of the superconducting cavity
