軸承座夾具設(shè)計(jì)

1、摘要根據(jù)所給題目軸承座接合面銑銑床卡具設(shè)計(jì)，設(shè)計(jì)專用卡具，在制定工藝路線時(shí)，主要根據(jù)加工工藝原則：先加工基準(zhǔn)面再加工其他表面，先安排主要表面的加工在安排次要表面的加工，先粗后精，先主后次加工等基本原則。軸承座接合面銑銑床卡具，主要包括定位元件、夾緊機(jī)構(gòu)、夾具體等部件。在以上結(jié)構(gòu)方案的基礎(chǔ)上，創(chuàng)建所有零件的三維實(shí)體模型庫(kù)，并完成夾具整體的三維實(shí)體裝配模型。本設(shè)計(jì)主要采用以下技術(shù)：通過(guò) Ug 軟件的三維實(shí)體建模技術(shù)和虛擬裝配技術(shù)，創(chuàng)建箱體夾
