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 desig
