沈陽理工大學(xué)學(xué)士學(xué)位論文 I 摘 要 我這次畢業(yè)設(shè)計的題目是球面切削專用設(shè)備 該專用設(shè)備的設(shè)計方案主要依據(jù)仿 形車削的工作原理 其中包括床頭箱的設(shè)計和進給機構(gòu)的設(shè)計 床頭箱要滿足 4 級變 速 并能在更換工件時迅速制動 進給機構(gòu)包括縱向進給液壓缸 橫向進給液壓缸 曲柄滑塊機構(gòu)和型槽 車刀的縱 橫兩方向移動均采用液壓驅(qū)動 因此液壓系統(tǒng)的設(shè)計是否合理直接影 響到機床的工作性能 在液壓系統(tǒng)中 床鞍及滑塊的運動方向分別由各自的三位四通 電磁換向閥控制 其運動速度由安裝在各自油缸回油路上的調(diào)速閥及二位二通電磁換 向閥聯(lián)合控制 由溢流閥調(diào)整系統(tǒng)油壓 調(diào)整后的數(shù)值可由壓力表測出 該設(shè)備的電氣部分采用 PLC 控制 它可靠性高 抗干擾能力強 結(jié)構(gòu)簡單 功耗 低 并由實際情況考慮 決定采用 F1 三菱系列 PLC 一個好的專用設(shè)備應(yīng)該達到 1 提高生產(chǎn)率和工人勞動生產(chǎn)率 顯著減輕工人勞 動強 2 工作穩(wěn)定可靠 使用壽命長 3 易于維修 成本低 根據(jù)理論驗證 上述方 案基本達到要求 關(guān)鍵詞 仿形車床 液壓系統(tǒng) PLC 沈陽理工大學(xué)學(xué)士學(xué)位論文 II Abstract The topic of this graduation project of mine is that the sphere cuts the dedicated device Operation principle of main basis profile modelling turning of design plan of this dedicated device Include the design of the bedside case and enter to the design of the organization The bedside case wants satisfied 4 grades to change speed and can apply the brake rapidly while changing the work piece Enter to the organization including getting vertical trough of slippery organizations of crank and type The vertical two horizontal directions of the lathe tool move and adopt the hydraulic pressure to urge so the design systematic in hydraulic pressure influences the working performance of the lathe directly rationally Among hydraulic pressure system bed saddle slip sport direction of piece control by one s own 3 electromagnetic reversing valve of Stone separately sport its speed install in each cylinder going back to transfer speed valve and 2 electromagnetic reversing valves 2 times jointly control oil passaging Is it flow valve adjust systematic oil pressure adjust number value after can be measured by the manometer to overflow A fine dedicated device should reach 1 Boost productivity and worker labor productivity lighten worker work strong notably 2 It is reliable that the work is steady have long performance life 3 Easy to maintain with low costs Verify according to theory above mentioned schemes reach demanding basically Keyword copying lathe hydraulic pressure system PLC
