The Design And Analysis And Optimization Of The Key Parts Of LG24 Wheel Lathe

With car become an essential for living people, while the aluminum alloy wheel hub as an important security of automobile parts, whose market demand has been increased, and the demand of the manufacturer of wheel hub dedicated machine tool has also been increased. Among them, the wheel lathe which has the characteristics of processing and high precision and high degree of automation is becoming more and more attention.According to the structure characteristics of aluminum alloy wheel hub and manufacturing methods, this paper is based on the LG24 wheel lathe as the research object to design the overall layout and mechanical structure. For calculation and selection of the main movement device, we want to get accurate formula of cutting force calculation stress, which the processing of aluminum cutting force mathematical model is established. To calculate and select the line feed device. The virtual prototype of wheel lathe has been established in Solid Works 2014, and interference checking has been took.By using ANSYS finite element analysis software, the slant bed which is the key part of the wheel lathe has been simulated analysis. First of all, we will analyze the stress of the slant bed. Secondly, the statics analysis has been carried out on the slant bed of the wheel lathe to check the strength and stiffness. Thirdly, dynamic analysis has been carried out on the slant bed of the wheel lathe to get the natural frequency and vibration mode that can ensure a stable and avoid resonance of its dynamic characteristics, which is based on the slant bed modal analysis and harmonic response analysis. Finally, the optimization design on the slant bed of the wheel lathe, which can effectively reduce the weight of the slant bed, achieves optimization. In order to further reduce the slant bed weight and to improve the strength and stiffness, the lightweight design on the slant bed, which selects the mineral casting to analysis, loses more weight and increases strength and the amplitude frequency is reduced.In this paper, the research on LG24 wheel lathe will provide certain technical support for the design and optimization of the same type of wheel lathe.
