4L22柴油機機體頂面精銑床設(shè)計
摘要
本文主要介紹了4L22柴油機機體頂面精銑床的設(shè)計。研究的主要問題是4L22柴油機機體頂面精銑床外觀圖設(shè)計和夾具設(shè)計。根據(jù)4L22柴油機機體的結(jié)構(gòu)、形狀和尺寸特點，4L22柴油機機體頂面精銑床外觀圖設(shè)計選用了通用部件：銑削頭、機械滑臺等，配以專用的夾具和立柱、側(cè)底座等基礎(chǔ)部件，采用立式布局形式組成一組合銑床；夾具的設(shè)計，采用三基面組合定位，采用機動夾緊方式，使用液壓斜楔夾緊裝置完成工件夾緊。該設(shè)計方案具有設(shè)計制造周期短，生產(chǎn)率高，加工質(zhì)量穩(wěn)定，工人勞動強度低，產(chǎn)品更新時，組合銑床上的通用部件仍可重新利用組成新的組合機床等優(yōu)點。經(jīng)過分析和精度驗算表明該設(shè)計方案能夠滿足4L22柴油機機體生產(chǎn)綱領(lǐng)要求，能夠保證4L22柴油機機體頂面的加工精度和表面質(zhì)量要求。

Design Fine Milling Machine Tool to Mill the 4L22 Diesel Engine Fuselage
Abstract
This article mainly introduced the design about the fine milling machine tool ,which was used to mill the top of the 4L22 diesel engine fuselage.It mainly focused on the design is the outward appearance chart and the jig.According to the diesel engine of the fuselage’s structure,shape, size, the design of the outward appearance chart, selected the interchangeable components,which includes the mechanical slip lable and the milling cutter unit, design the special-purpose jig and the basic parts of colum, side foundation to form a vertical complete milling machine tool. In the design of the jig, it used three basic plane combinations localization.Simultaneously,in order to reduces worker’s labor intensity and non-cutting time, using hydraulic pressure to clamp. With hydraulic pressure wedge clamp installment to complete the work piece clamping. This design proposal has many advantages,such as, the cycle of the design and manufacture is short, the cost of the manufacture is low,high productivity, stable processing accuracy, and the interchangeable components still can reuse to form a new complete milling machine tool ,when the product is renewal. Being analysed and precison computed, this milling machine tool can meet the product efficiency , processing accuracy and superficial demand.
Key words：Milling cutter unit ; Mechanical slip lable ; Block milling machine tool ; Jig
