The invention discloses a resonance frequency digital control amendment method of the piezoelectric transducer and super-sound concentrator. The piezoelectric transducer and super-sound concentrator assembled together are installed at the digital control lathe by the flange at the pitch point of the super-sound concentrator. The anode and the cathode of the piezoelectric transducer are respectively connected to the anode and the cathode of the frequency analyzer. The frequency analyzer is measured the resonance frequency of the piezoelectric transducer and super-sound concentrator at real time, and transferred the tested actual resonance frequency parameter to the computer to calculate out the difference value of the actual and theoretical resonance frequency, the amendment position and the amendment allowance of the piezoelectric transducer and super-sound concentrator. The piezoelectric transducer and super-sound concentrator are practiced precision finishing ultra-precision machining by the servo motor drive cutter to change their shape and size. The advantage of the invention are that the amendment efficiency is high; the amendment frequency is accurate; the piezoelectric transducer and super-sound concentrator will not be discarded as useless; the cost is low; the operation is simple; and the automatic amendment can be realize. |
