摘要

Y41系列單柱校正壓裝液壓機(jī)，是一種多功能的中小型液壓機(jī)床，適用于軸類(lèi)零件，型材的校正和軸套類(lèi)零件的壓裝。它采用手腳聯(lián)動(dòng)操作，通過(guò)電動(dòng)機(jī)帶動(dòng)液壓泵向主油路供油，通過(guò)溢流閥，手動(dòng)換向閥等控制閥對(duì)液壓系統(tǒng)進(jìn)行調(diào)壓換向，以達(dá)到各種工作狀態(tài)。
該液壓機(jī)結(jié)構(gòu)緊湊，動(dòng)作靈敏可靠，速度快，能耗小，噪音低，壓力和行程可在規(guī)定的范圍內(nèi)任意調(diào)節(jié)，操作簡(jiǎn)單。在本設(shè)計(jì)中，通過(guò)查閱大量文獻(xiàn)資料，設(shè)計(jì)了液壓缸的尺寸，擬訂了液壓原理圖。按壓力和流量的大小選擇了液壓泵，電動(dòng)機(jī)，控制閥，過(guò)濾器等液壓元件和輔助元件。
