针对现有的便携式电火花打孔机质量太大、加工效率低等问题,在分析总结了现有的便携式电火花打孔机研究现状的基础上,提出了一种滑块静止而导轨运动的执行机构设计方案。基于单片机,研究了直接利用RC比较电路以简化放电回路的方法,使用了千分表座作为便携式电火花打孔机的底座以调整打孔面,制作出的便携式电火花打孔机重量减轻至10kg以内,测得材料去除率达到了15mm3/min以上,且打孔面易于调整。设计结果表明:所优化的执行机构、放电回路、打孔面调整装置减轻了便携式电火花打孔机的重量,提高了加工效率,且工作稳定。

Aiming at weight and efficiency problems of portable EDM drilling machine, the research status of EDM drilling machine were analyzed and summarized, a design plan that keep the slider stay to let guideway movement was put forward.The way that single chip microcomputer directly take the advantages of RC comparison circuit to simplify discharge circuit was studied , micrometer pedestal was used as a base of portable EDM drilling machine to adjust the perforated surface.The weight of portable EDM drilling was made reduce to less than 10 kg , tested data showed the material removal rate up to 15 mm 3/min, and perforated surface easy to adjust.The results indicate that the optimized actuator, discharge circuit and perforated surface adjustment device reduce the weight of portable EDM drilling machine , improve working efficiency, the work is stable.
