描述

是什么問題導致這一故障的發(fā)生？我們對松刀緊刀的兩個電磁閥進行了電氣檢查，松刀緊刀的兩個電磁閥是直流：24V電壓正常，電磁閥線圈有阻值，說明沒有接地和燒壞。松刀和緊刀的兩個指令兩個電磁閥執(zhí)行的正確，液壓泵的液壓壓力也在6MPa以上，符合工作要求。我們對液壓閥進行維修檢查，將松刀和緊刀的兩個液壓電磁閥拆掉，用煤油進行了閥芯的清洗，安裝試機仍然會出現(xiàn)液壓缸拉不緊刀返回松刀現(xiàn)象，與之相關(guān)聯(lián)的電氣和液壓部分都檢查后沒有發(fā)現(xiàn)問題。結(jié)合上述分析，再進一步檢查就是松刀、緊刀的主液壓缸了。松緊刀液壓缸的工作原理是：松刀是液壓缸的上端油腔經(jīng)松刀電磁閥提供高壓液壓油向下壓主軸上的碟簧，克服碟簧的彈力將刀具壓下；緊刀是利用刀桿上的疊簧向上的彈力，將上液壓缸內(nèi)的液壓油經(jīng)緊刀電磁閥排出，使刀具向上拉緊。
