PORTABLE FRICTION WELDING MACHINE

摘要

A portable friction welding machine is provided with a pair of ram mechanisms which provide the necessary axial pressure during a welding operation and also operate to move a spindle of the welding machine to a position where the spindle may be pivoted outside the main machine body so that flywheels may be easily attached or removed from the spindle. The machine is also provided with an automatic disconnect mechanism between the drive motor and the spindle which disconnects the motor from the spindle upon the application of welding pressure through the rams.
