0146-連桿雙端面銑削組合機床主軸箱及夾具設(shè)計,連桿,端面,銑削,組合,機床,主軸,夾具,設(shè)計 組合機床主軸箱及夾具設(shè)計 摘 要:根據(jù)設(shè)計任務(wù)書的要求,本設(shè)計說明書針對連桿大小頭雙端面銑削組合機床的設(shè)計及專用夾具設(shè)計進(jìn)行說明。主要內(nèi)容包括組合機床工藝方案的制定、組合機床配置型式的選擇、組合機床總體設(shè)計以及主軸箱設(shè)計。 全文主要包括組合銑床的總體設(shè)計和主軸箱設(shè)計兩部分。機床總體設(shè)計主要是在選定工藝方案并確定機床配置形式、結(jié)構(gòu)方案基礎(chǔ)上確定“三圖一卡”，主軸箱設(shè)計根據(jù)“三圖一卡”，整理編繪出主軸箱原始依據(jù)圖，重點分析傳動系統(tǒng)，經(jīng)過各種方案的比較，最后確定最優(yōu)方案。此外，為了提高勞動生產(chǎn)率，降低勞動強度，保證加工質(zhì)量，需設(shè)計專用夾具。 關(guān)鍵詞：主軸箱；組合機床；夾具 Combination Machine Tool Spindle boxes and fixture design Abstract:According to designs the project description the request,This design instruction booklet carries on the explanation in view of the connecting rod reducing socket double face milling aggregate machine-tool design and the unit clamp design. Main content including aggregate machine-tool craft plan formulation, aggregate machine-tool configuration choice, aggregate machine-tool system design as well as headstock design. The full text mainly includes combines the milling machine the system design and the headstock designs two parts. The engine bed system design mainly is in the designation craft plan and the determination engine bed disposition form, in the structure plan foundation determined "a three charts card", the headstock design basis "a three charts card", reorganizes the compilation to leave the headstock primitive basis chart, the key analysis transmission system, passes through each kind of plan comparison, finally determines the most superior plan. In addition, in order to enhance the labor productivity, reduces the labor intensity, guaranteed the processing quality, must design the unit clamp.
