变速器壳体卧式双面专用攻丝机床设计 [摘要]专用机床是用按系列标准化设计的通用部件和按加工零件的形状及加工要求设计的专用部件组成的机床。其通用部件已经标准化和系列化， A Horizontal Type’s Two-sided Special Use Tapping Machine Tool Design for Light Vehicle’s Gearbox [Abstract]A Special Purpose Machine is designed by the series of standardized common components and parts by processing the shape and design of special processing requirements of the special machine tool components. Its generic components 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 combination 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 dollars analytical software to carry on dependable sex analysis to the tool machine main parts.
