Wireless pressure sensor is sheathed on correspondingly on each pre-stressed bolt, and each circular ring shape strain chip wireless pressure passes
Sensor is located at the head of each first counter sink correspondingly；Each circular ring shape strain chip wireless pressure sensor one is a pair of
It is located at the lower section of each disk spring with answering.When work, each circular ring shape strain chip wireless pressure sensor acquires in advance in real time
Stress signal, and collected prestressing force signal is sent to computer in real time and is shown, computer is according to prestressing force signal
Can real-time judge circle relaxor ferroelectric monocrystal piece whether uniform force.
Further, the density of circular upper lid is greater than the density of round lower cover.When work, this design can have
Effect prevents longitudinal ultrasonic frequency vibration to be communicated up through circular upper lid.
Structure of the invention is reasonable, ingenious in design, and it is low, unsuitable to efficiently solve existing industrial ultrasonic transducer output power
It works long hours, the problem that overall power is limited, using flexible is poor, electromechanical conversion efficiency is low, is suitable for various Ultrasonic machinings
