1、 臥式雙面十軸組合鉆床左主軸箱設(shè)計(jì)及性能仿真 摘要 組合鉆床是一種專用機(jī)床，它的大部分部件是通用件，少部分部件是專用件。這種鉆 床有很高的效率。而且因?yàn)楦呱a(chǎn)效率，平穩(wěn)的加工精度，自動(dòng)化水準(zhǔn)高，有效減少了人 工勞動(dòng)強(qiáng)度。 此次設(shè)計(jì)任務(wù)是用來(lái)生產(chǎn)制造 “汽車制動(dòng)室支架”的臥式雙面十軸組合鉆床。設(shè)計(jì)的 組合鉆床用來(lái)加工汽車支架的兩個(gè)零件，主要是同時(shí)鉆孔。鉆床的左主軸箱鉆 6 個(gè)孔

2、，右 主軸箱鉆 4 個(gè)孔，我主要設(shè)計(jì)任務(wù)是組合鉆床的左主軸箱，并用 PRO/E 對(duì)結(jié)構(gòu)進(jìn)行仿真和 干涉檢查，對(duì)左主軸箱的主要零件進(jìn)行 ANSYS 靜力分析。 從加工孔的速度和位置需求出發(fā)，計(jì)算得切削速度及主軸轉(zhuǎn)速，對(duì)左主軸箱的主軸型 號(hào)、直徑及輪廓尺寸進(jìn)行選型。然后由驅(qū)動(dòng)軸轉(zhuǎn)速和位置、各主軸形位和旋轉(zhuǎn)速度快慢的 要求，正確放置傳動(dòng)軸，把驅(qū)動(dòng)軸及每個(gè)主軸連接起來(lái)，讓每個(gè)主軸達(dá)到理想轉(zhuǎn)向和轉(zhuǎn)速， 成功鉆孔。 運(yùn)用 PRO/E 機(jī)

3、械模塊對(duì)左主軸箱的結(jié)構(gòu)進(jìn)行運(yùn)動(dòng)仿真，測(cè)量位置、速度和加速度等運(yùn) 動(dòng)特征，對(duì)結(jié)構(gòu)進(jìn)行干涉檢查。運(yùn)用 ANSYS 對(duì)傳動(dòng)軸和箱體進(jìn)行應(yīng)力、應(yīng)變和模態(tài)分析。 關(guān)鍵詞 組合鉆床；左主軸箱設(shè)計(jì)；運(yùn)動(dòng)仿真分析；有限元分析 I Abstract Combination drilling machine is a kind of special machine tool, its mos
