一个牧田电锤的芯片级维修复活
一个牧田电锤的芯片级维修复活，牧田HR2010电锤，买的闲鱼货，260，只钻不锤，拆解修复，收获颇多。网传假牧田电锤很多，拆解之后发现做工这么复杂，即便是个假的，复刻做工这么优良考究，假的又何妨。壳体、电机、控制其实不复杂，复杂在于气缸冲击部分和四方套以及夹头。后面有图片说明它的工作原理。动力传给伞齿之后，有一个离合器，离合的作用估计是卡钻之后防止扭伤人，所以操作电锤要握紧，机器会自动保护你。活塞负责压缩空气，活塞不直接击打钻头，通过往复空气煽动大锤运动，大锤也不直接击打钻头：大锤在气缸内运动，击打小锤，也就是“冲击子”，冲击子的行程很小，大概6-8mm，它击打钻头。所以能量多少焦取决于大锤，而不是冲击子。看图应该明白了：https://piczuojiaju.diy.cc/pic/20220508/1651983113396871978.jpg?watermark/1/image/aHR0cHM6Ly9tZ2ltYWdlLmRpeS5jYy9waWMvMjAxODExMTMvcWlfbml1XzE1NDIwNzgxOTE5MzZfODlfNDQ0XzY5OS5wbmc=/dissolve/50/gravity/SouthEast/dx/20/dy/20

是个狼灭
手机打字好累，还有好多收获，就没描述了，在电锤里面钢珠很普遍。 做感觉拆这种的东西安上后多两个螺丝https://mgm.diy.cc/public/emotion/face_026.png 未落 发表于 2022-05-08 15:10

我今天路过机械设备市场 里边好多宝藏，看中一款日立的螺丝批 要600大洋带一电一充，下次再去收
带离合功能的还是很实用的，钻大孔，深孔的时候能保障安全。 东城有兼容件
