Abstract

Combined with the working principle and failure mechanism of the three-spindle precision drilling and milling vertical machining center, the X-swing and Y-axis torsion of the spindle system in the three-order vibration mode of the machining center spindle system, the Z-direction torsion of the four-order vibration mode of the spindle system, the Y-direction torsion of the five-order vibration mode of the spindle system, and the Y-swing of the six-order vibration mode of the spindle system accompanied by rotation around the z-axis were analyzed. The main shaft system is analyzed statically. Select the center point of the end face on the spindle system combined with the three spindles, and apply 1500N load in the X-direction , Y-direction and Z-direction respectively to observe the deformation and stress. Through comparison, it is found that the peak value of the amplitude-frequency curve in all directions after optimization also has different amplitude reduction, the maximum peak value in the X-direction decreased by 34.71%, the maximum peak value in the Y-direction decreased by 22.21%, and the maximum peak value in the Z-direction decreased by 19.29%, indicating that the optimization of the spindle system has significantly improved the dynamic performance of the machine tool in all directions.
