摘 要
我這次畢業(yè)設(shè)計(jì)的題目是球面切削專用設(shè)備。該專用設(shè)備的設(shè)計(jì)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(jì)和進(jìn)給機(jī)構(gòu)的設(shè)計(jì)。床頭箱要滿足4級變速，并能在更換工件時(shí)迅速制動。進(jìn)給機(jī)構(gòu)包括縱向進(jìn)給液壓缸、橫向進(jìn)給液壓缸，曲柄滑塊機(jī)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(jì)是否合理直接影響到機(jī)床的工作性能。在液壓系統(tǒng)中，床鞍及滑塊的運(yùn)動方向分別由各自的三位四通電磁換向閥控制，其運(yùn)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(qiáng)，結(jié)構(gòu)簡單，功耗低，并由實(shí)際情況考慮，決定采用F1三菱系列PLC。
一個(gè)好的專用設(shè)備應(yīng)該達(dá)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(qiáng).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(yàn)證，上述方案基本達(dá)到要求。

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.
