Its generic ponents have been standardized and serialized, the application can be selected, greatly shortened the design and manufacturing cycle. Combination of machine tool with low cost, high efficiency characteristics, Therefore a large number of extensive production of a large number of applications. And as technology advances, degree of automation and CNC continuously improved. This paper mainly introduces the bination machine tool designed for tapping holes in link surface of gearbox casing of light vehicles. It includes the total project design of the machine, the selection of general use parts, the design of spindle box etc. The process of selecting in general use parts and the principle and process of selecting the spindle box is elaborated on, and the strengthen of the shaft were analyzed in detail. Drew tool machine to always pack a diagram, principal axis box the wheel gear Nie match a principle diagram, principal axis box total assemble diagram and necessary spare parts diagram etc., and made use of limited dollar39。s analytical software to carry on dependable sex analysis to the tool machine main parts.
