FRICTION WELDING DEVICE

摘要

A friction welding device allows one work (5) and the other work (9) to be in contact with each other and gives friction thrust thereto, giving a fixed relative rotation operation to the one work (5) and the other work (9) by energizing a servo motor (15) and rotating a main shaft (3), and thereby softens a connection interface between the works (5, 9). Then, the friction welding device decelerates the main shaft (3) until the number of the rotation of the main shaft (3) is set to the number of phase focusing rotation, and when the number of the rotation of the main shaft reaches the number of the phase focusing rotation, allows a clutch device (19) to be engaged with the main shaft, shuts off the energization to the servo motor (15), and thereby stops the rotation of the main shaft (3).
