国内在气动凿岩机具的设计与研制方面,多年一直采用经验设计方法,研制周期长,费用高,且难以达到产品性能优化的要求。近年来我们结合气动冲击器和凿岩机等产品设计,利用计算机辅助设计方法,根据设计的要求,由计算机提出不同的设计方案,从而优选出最佳的结构参数。YGZM-40型凿岩机是我国新型的导轨式 Domestically, in the aspect of design and development of pneumatic rock drilling tools, experience design methods have been adopted for many years, the development cycle is long, the cost is high, and it is difficult to achieve the requirements for product performance optimization. In recent years, we combined the design of pneumatic impactors and rock drills with computer-aided design methods. According to the design requirements, different designs were proposed by the computer to optimize the structural parameters. YGZM-40 Rock Drill is a New Type of Guide Rail Type in China
