課題零件攻絲中文摘要

1、中文摘要中文摘要組合機(jī)床是由大量的通用部件和少量專用部件組成的工序集中的高效率專用機(jī)床。它能夠?qū)σ环N零件進(jìn)行多刀、多軸、多面、多工位加工。在組合機(jī)床上可以完成鉆孔、擴(kuò)孔、銑削磨削等工序，生產(chǎn)效率高，加工精度穩(wěn)定。本課題為設(shè)計單工位單面攻絲組合機(jī)床，用于加工翻斗車主傳動殼體螺紋孔。在攻絲組合機(jī)床的設(shè)計上采取了一系列的措施，保證了被加工孔的加工精度。主要完成了對翻斗車主傳動殼體的螺紋孔的加工工藝進(jìn)行了分析研究，明確了各個孔加工的技術(shù)要求和工

2、藝要點。恰當(dāng)?shù)剡x擇了機(jī)床的切削參數(shù)，動力頭及液壓滑臺驅(qū)動機(jī)構(gòu)的結(jié)構(gòu)參數(shù)。設(shè)計了穩(wěn)定可靠的多軸箱，從而保證了被加工孔的精度要求。根據(jù)通用、經(jīng)濟(jì)的原則，選擇了刀具，滿足了工藝的需要。機(jī)床為四軸攻螺紋立式組合機(jī)床。主軸設(shè)為機(jī)械傳動，而進(jìn)給系統(tǒng)為液壓控制，使在滿足使用要求的前提下降低了成本。作為關(guān)鍵部件的液壓滑臺采用通用部件。以比較簡單的方式完成旋轉(zhuǎn)運(yùn)動和直線運(yùn)動的同步進(jìn)行，非常實用。設(shè)計的機(jī)床，保證了加工螺紋的生產(chǎn)質(zhì)量，提高工效3倍以上，加工

3、成本大幅下降。本項工作還有許多值得完善的地方，例如：自動化程度有待提高等問題。這些問題通過改進(jìn)設(shè)計、完善工藝、現(xiàn)場的不斷實踐、總結(jié)，必將會得到進(jìn)步的提高。AbstractTheaggregatemachinetoolisthewkingprocedurecentralizedhighefficiencyspecialpurposemachinewhichiscomposedofthemassivegeneralpartsthefewsp
