Design and Development of Automatic Drilling Machine for Multi Hole Bulletproof Helmet
多孔位防弹头盔自动钻孔机的设计与开发

摘要

常见防弹头盔所钻孔位基本为四孔位和五孔位。目前国内外防弹头盔都增加了夜视仪，实现单兵信息化系统的搭载，需在五个工位钻出六个安装孔，钻孔工序以手工为主，需要先标记钻孔位置，再逐个工位进行手工钻孔，很难保证各孔位的精度。为解决上述问题，设计开发了多孔位防弹头盔自动钻孔机，阐述了钻孔机整机构成、工作流程，详细介绍了头盔自动抓取/放回头盔装置、钻孔工作台和头盔钻孔定位装置及顶出头盔装置、多功能调节底座以及气电钻孔装置等零部件结构和工作原理，并分析了钻孔外观效果。结果表明，该钻孔机解决了人工钻孔劳动强度大、精度差、生产效率低等问题，对防弹头盔生产企业具有一定的参考借鉴作用。

Abstract

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.
