Abstract

This paper, we mainly studied and designed the main box drive structure of VMC950G machining center. In the professional direction of mechanical structure design, this paper comprehensively uses the basic theories of mechanical principle, mechanical design and mechanical manufacturing equipment design, and carries out the detailed transmission structure design of the feed shaft and spindle of VMC950G machining center. The machining center is mainly used for the parts with high precision, many processes and complex shapes, such as plate type, plate type, shell parts and mold. In the design process, the technical parameters requirements of the transmission structure of the spindle box are clarified, including the spindle speed range, power output, the distance from the center to the guide rail and the rated power of the motor, etc. Subsequently, by consulting the relevant background information, the overall scheme of the spindle gearbox drive structure is determined, and the system design and calculation. In addition, this paper involves the structural design of the spindle box, spindle, drive shaft and transmission parts, the selection of motor, bearing and standard parts, as well as the spindle box assembly drawing and parts drawing. Finally, the design specification is written to provide detailed technical documents for the design of VMC950G machining center.
