The drilling positions of common bulletproof helmets are basically four holes and five holes. At present, bulletproof helmets at home and abroad are equipped with night vision devices to carry individual information systems. It is necessary to drill six installation holes in five stations. The drilling process is mainly manual. It is necessary to mark the drilling position first, and then manually drill holes one by one. It is difficult to ensure the accuracy of each hole location. In order to solve the above problems, an automatic drilling machine for multi hole bulletproof helmet is designed and developed. The composition and working process of the drilling machine are described. The structure and working principle of the helmet automatic grabbing/putting back helmet device, drilling workbench, helmet drilling positioning device, helmet ejection device, multifunctional adjusting base, and pneumatic drilling device are introduced in detail. The drilling appearance effect is analyzed. The results show that the drilling machine solves the problems of high labor intensity, poor accuracy and low production efficiency of manual drilling, and has a certain reference role for bulletproof helmet manufacturers.
