"组合机床滑台及底座设计与主轴组件研究"

The content discusses the design of the slide table and base of a combination machine tool for the machining process of the six holes on the flange on the rear axle shaft of a tracked tractor. It primarily focuses on the design of the guide rails, support components, and the spindle assembly, including the design of the support components such as the slide table, slide table body, and slide table seat. The overall layout of the machine tool determines the various components of the machine. The guide rail design includes the selection of guide rail types, determination of cross-sectional shape, structural dimensions, pressure testing, material selection and heat treatment, lubrication and protection devices, and technical requirements for guide rail manufacturing. The design of support components involves determining the minimum wall thickness, partition plates and reinforcement ribs, material selection and aging treatment, the rationality of process structure, and size determination. The spindle assembly design includes spindle drive, determination of spindle diameter, lubrication and sealing, selection of spindle rolling bearings, determination of spindle box profile dimensions, and design of the spindle box transmission system. The key words include combination machine tool, spindle box, slide table, guide rail, support components, and spindle assembly.
