The invention discloses a high-frequency eccentric vibration
acoustic wave power head for a drilling
machine, and belongs to the field of
audio frequency drilling machines. The high-frequency eccentric vibration
acoustic wave power head for the drilling
machine comprises a main frame, a spindle rotating mechanism, a spindle vibrating mechanism and a bearing cooling lubricating
system. Structurally, a spindle and a spindle
hydraulic motor adopt spline structures for transmission connection, the spindle is rotationally connected into a spindle box, the spindle box is mounted in the main frame inthe mode of hanging in air through a vibration
isolator, high-frequency vibration is generated through two sets of eccentric vibration mechanisms in the spindle box, thus the
acoustic wave power headis more compact and more reasonable in structure, and spindle rotation and
axial vibration movement are more stable and more reliable; and meanwhile a vibrator shaft bearing is cooled and lubricatedby lubricating oil through a lubricating oil circulation
control system, the
working temperature of the vibrator shaft bearing is greatly decreased, the service life of the bearing is prolonged, thusthe eccentric-vibration-type acoustic
wave power head can work at a higher vibration frequency, and the working efficiency of the acoustic
wave power head is further improved.
