摘要：
隨著自動(dòng)化生產(chǎn)能力的提高，現(xiàn)代工廠中出現(xiàn)需要組合機(jī)床的場(chǎng)合越來越多，組合機(jī)床是以通用部件為基礎(chǔ)，配以工件特定外形和加工工藝設(shè)計(jì)的專用部件和夾具，組成的半自動(dòng)或自動(dòng)專用機(jī)床。它一般采用多軸，多刀，多工序，多面或多工位同時(shí)加工的方式，生產(chǎn)效率比通用機(jī)床高幾倍至幾十倍。由于通用部件已經(jīng)標(biāo)準(zhǔn)化合系列化，可根據(jù)需要靈活配置，能縮短設(shè)計(jì)和制造周期。因此，組合機(jī)床兼有低成本和高效率的優(yōu)點(diǎn)，在大批量生產(chǎn)中得到廣泛應(yīng)用，并可用以組成自動(dòng)生產(chǎn)線。
本課題針對(duì)變速箱殼體端面上12Xφ18孔鉆削這一特定工序而設(shè)計(jì)的一臺(tái)專用立式組合機(jī)床。
本設(shè)計(jì)中，在充分?jǐn)?shù)據(jù)計(jì)算的基礎(chǔ)上對(duì)標(biāo)準(zhǔn)通用零件做了仔細(xì)選擇，并依據(jù)被加工零件的結(jié)構(gòu)特點(diǎn)，加工部位的尺寸精度，表面粗糙度要求，以及定位夾緊方式，工藝方法和加工過程中所采用的刀具，生產(chǎn)率，切削用量情況等設(shè)計(jì)了結(jié)構(gòu)合理的多軸箱。

Title Gearbox Shell Drill Machine Design (Porous Three
Diagram A Card and Spindle Box)
Abstract
With automatic production capability is improved, the modern factories in need of modular machine tool, the combination of more occasions based on general parts, match with workpiece specific shape and process design of special components and fixtures, composed of semi-automatic or automatic special machine. It usually adopts the multiaxial, knife, processes, and multi-faceted or multistage and processing, production efficiency than general machine high several times or more. Due to the common parts have standard series, can according to the combined flexible configuration, can shorten the cycle of design and manufacture. Therefore, the combination machine has the advantages of low cost and high efficiency, in large, mass production is widely used, and the automatic production line can be used to composition.
This paper introduces a special vertical combination machine tools designed for gearbox shell 12X φ 18 holes on the surface drilling this specific processes.
In this design, all the standard parts selection based on the carefully data calculation, and according to the characteristics of the structure by processing components, precision machining parts size, surface roughness, and the localization way, clamping technology and processing process using tools, cutting dosages as productivity, the structure design of reasonable spindle box.
Keywords：combined machine tool, production efficiency, clamp, drilling
