Abstract:

The static and dynamic characteristics of the swing shaft of ball feeding mechanism is of great significance in the ball feeding stability,the success rate for ball feeding and ball mounting.Therefore,it is necessary to conduct the static and dynamic characteristics of the swing shaft simulation analysis.A simplified swing shaft mechanical model is established and the finite element analysis software ANSYS is used for a static analysis of swing axle swing angle of  0° intermediate position and ±45° limit position to obtain the stress and deformation nephogram of the shaft wobble at these positions.The modal analysis of the swing shaft is carried out,and the natural frequency and the vibration form of the first six natural frequencies are obtained.The results show that the preliminary design of the swing shaft meets the design requirements and that the swing angle±45°  position is the dangerous position.It provides references for the subsequent design and optimization of the ball mechanism.
