The invention discloses an aluminum strip drilling device for a hollow glass molecular sieve filling machine. The aluminum strip drilling device comprises a main rotary disc, a pneumatic drilling device and drill bit converting frames. At least four semicircular grooves are evenly formed in the outer circumference of the main rotary disc and internally provided with positioning rotary discs. The pneumatic drilling device is connected with the positioning rotary discs through clamping mechanisms. A boosting hydraulic cylinder is arranged at the bottom of the main rotary disc and connected with a horizontal supporting plate through a piston rod. A motor is arranged on the top face of the horizontal supporting plate. Inner cavities are formed in the positioning rotary discs. Annular racks are arranged on the side walls of the inner cavities. The drill bit converting frames are evenly distributed on the outer circumference of the main rotary disc. The aluminum strip drilling device is simple in structure and high in practicability, and aluminum strips of different sizes and specifications can be drilled. Flexible replacement of drill bits can be automatically achieved, the remote positions and the positions hard to machine can be drilled, and the work range of the pneumatic drilling device is widened; and meanwhile the stability of the pneumatic drilling device during rotating is improved.
