碩士 / 國立虎尾科技大學 / 機械與電腦輔助工程系碩士班 / 107 / Nowadays, the machine tool is gradually developing at a high speed, and the high heat caused by the high-speed built-in spindle is prone to thermal deformation, which leads to the precision during processing. To solve this problem, the Republic of China Patent No. I622255 proposes a new flow fin. Designed to not change the main shaft design, only the fin design is added to the original cooling water flow channel, which does not affect the dynamic balance and can effectively achieve the thermal suppression effect. The fin design concept is to increase the turbulence of the coolant in the flow channel to increase the turbulence in the flow channel. In addition, the multiple fin design can increase the contact area of the coolant and take more heat.
In order to verify the performance of the I622255 patent, this research method uses the finite element software (ANSYS) to simulate and analyze the mold of the planar water flow channel design, observe the results and verify the effective theoretical model of the simulation analysis by simulation test, and finally carry out the actual spindle water jacket. CAE simulation analysis to observe the cooling effect of the actual spindle. If the development of the spindle water jacket fins is carried out in the future, it is not suitable for the optimization of the experimental research directly. The main reason is that the cost of the main shaft is too high. The part of the physical experiment should be performed after the simulation analysis and the establishment of an effective theoretical model, followed by the simulation optimization analysis.
This study confirmed that the finned flow channel has a relatively good cooling effect. The heating temperature of 70 °C was set on the simulation analysis of the plane water channel mold, and the effect of cooling with or without fins was 3.5K. However, the presence or absence of the simulation test and the fin mold also have a temperature difference of 3 °C. The simulation analysis and test have certain validity, so it is possible to establish the theoretical parameters and model of the spindle water jacket. For the analysis of the spindle water jacket cooling system, the simulation results of the fin water jacket are obtained from the surface temperature and the water outlet and the fluid vector diagram. The fin water sleeve design can make the surface temperature better than the finless water jacket model. The low range shows that there is a temperature difference of about 7K between the fins and the finless water jacket at different points, so that the theoretical model can be used to know the difference between the fins and the fins
