The invention relates to a spring installation device used for a clutch disc hub. The spring installation device is characterized in that the device comprises a workbench (1), a spring placement mother plate (2) and a plucking piece disc (3), multiple spring feeding notches (2, 3) are evenly formed in the spring placement mother plate (2) in the circumferential direction of a clutch disk hub central registration hole (2.2), the plucking piece disc (3) comprises a base disc (3.1) and multiple plucking pieces (3.2) which are evenly arranged in the circumferential direction of the top face of the base disc (3.1), the spring feeding notches (2, 3) correspond to the plucking pieces (3.2) in number, the multiple plucking pieces (3.2) extend into the multiple spring feeding notches (2, 3), and the plucking piece disc (3) is rotated through a power mechanism, so that the positions of the plucking pieces (3.2) in the spring feeding notches (2, 3) are movably adjusted. The spring installation device has the advantages that the spring installation position is made to be accurate and unified, labor intensity of workers is lowered, production efficiency is improved, and safety performance is high.
