Study on Oblique Cam Type Mechanical Torsional Vibrator

Vibrator is the key part of vibration tapping machine. In this paper, a kind of oblique cam type mechanical vibrator was designed. The vibrator has the advantages of simple structure and easy manufacturing, and the output amplitude of the vibrator can be adjusted by changing the inclination angle of oblique cam. It is verified by experiments that the process is successful when the oblique cam type vibrator is used to machine big thread holes, and compared with common continuous tapping, the torque of vibration tapping decreases significantly.
