- 1 -摘 要為對(duì)變速箱殼體端面銑削加工,我們進(jìn)行此次專用夾具設(shè)計(jì)。變速箱零件為鑄件,零件形狀復(fù)雜,在定位時(shí),選一面兩銷的定位方式定位,并以操作簡單的手動(dòng)夾緊方式夾緊,其機(jī)構(gòu)設(shè)計(jì)簡單,方便且能滿足要求。關(guān)鍵詞:變速箱殼體,銑面加工,專用夾具,設(shè)計(jì)Design of Clamping Device for The Gearbox Shell Face MillingAbstract: This design is about the shell of the gearbox face milling clamp design.The parts is casting ,and it have complex shape.When processesing,we need take it in right position,so we chooses locate mode which two sells at the same time, and operates the simple manual clamp way clamp, its organization design is simple, the convenience also can satisfy the request. Key words:Shell of The Gearbox,Milling Face, Unit Clamp,Design of Clamping Device.- 2 -目 錄一.前言 - 1 -二.設(shè)計(jì)任務(wù) .- 2 -三.銑床夾具的主要類型與特點(diǎn) .- 3 -3.1 銑床夾具的主要類型 .- 3 -3.2 銑床夾具的特點(diǎn) .- 3 -四.對(duì)加工工件進(jìn)行工藝分析 .- 3 -五.定位方案設(shè)計(jì) .- 3 -5.1 工件與夾具體的定位 .- 3 -5.2 夾具體與機(jī)床的定位 .- 4 -5.3 定位誤差計(jì)算 .- 4 -六.夾緊方案設(shè)計(jì) .- 6 -6.1 銑削力的計(jì)算 .- 7 -6.2 夾緊力的計(jì)算 .- 8 -七.夾具體與其它裝置設(shè)計(jì) - 10 -7.1 夾具體設(shè)計(jì) - 10 -7.2 其它裝置設(shè)計(jì) - 11 -八.技術(shù)條件制定 - 12 -九.夾具精度分析 - 12 -十.夾具工作原理簡介 .- 13 -十一.總結(jié) .- 14 -參 考 文 獻(xiàn) .- 15 -致 謝 - 16 -
