ABSTRACT


Aiming at the problems of large volume, large noiseinconvenient useinsufficient thrust and short life of the existing nail shooting device, a kind of nail shooting device driven by voice coil linear motor with magnifying mechanism was designed and manufactured. Firstly, the components and working principle of the nail shooting device were analyzed. Secondly, the mathematical model of the magnetic field driving force of voice coil linear motor was established, and the simulation calculation of the electromagnetic field of the motor was carried out. The influence of the excitation current, the position of the shaft core, the length of the shaft core, and the diameter of the shaft core on the electromagnetic force acting on the shaft core was studied. Then the working principle of magnifying mechanism was studied. Finally, the nail shooting device was made and tested. The results showed that the volume of the nail shooting device was ϕ40×60 mm 3, the mass is 550g, the maximum thrust is 154N, the nail speed can reach 21 m/s, the stable thrust is 120N, and the service life is 1500h.
