The invention discloses a double-rotating-tower combined type automatic pump core assembly machine comprising a main motor, an auxiliary motor and a rack. The main motor is mounted on the rack through motor mounting plates. An inner piston vibrating plate, a spring vibrating plate, a pump body vibrating plate, a piston vibrating plate, a lower glass ball cup, a human-machine operation interface, a system bracket and a discharging scraper-trough conveyer are mounted on the rack through a table plate. The main motor is connected with a clutch wheel through motor wheels and a belt. The clutch wheel is connected with a material receiving rotating plate provided with an upper punch. An upper cam is mounted on the upper punch through a supporting plate. The auxiliary motor is connected with a main divider connected with a pump body rotating plate. A spring feeding groove is formed in the system bracket and connected with the spring vibrating plate, and the pump body rotating plate is connected with the material receiving rotating plate through a direct-vibrating track. The double-rotating-tower combined type automatic pump core assembly machine has the beneficial effects that practicability is achieved, using is convenient, automatic pump body assembling is realized in the production process of a sprayer, and the production efficiency is improved.
