[0038] The above-mentioned excitation device 4 is a finished ultrasonic knife.

[0039] The working principle of the utility model is as follows:

[0040] First, the ultrasonic knife rod is rigidly connected to the transducer, and the transducer is fixed in the clamping area surrounded by the positioning block and the clamping block;

[0041] When in use, the laser beam emitted by the laser generator will irradiate the end face of the ultrasonic knife rod head, and the generated reflected light will be received by the receiving screen to form a light spot. Therefore, when the ultrasonic knife rod is stationary, the movable block is driven to move in the vertical direction by turning the knob, thereby changing the height of the test module, so that the light reflected by each ultrasonic knife rod during the test can fall on the center of the receiving screen and form a light spot, thereby zeroing it to ensure the accuracy and efficiency of subsequent tests. At this time, the light spot position is set to zero, ensuring that the receiving screen can receive the reflected light spot during the subsequent test process, thereby improving the accuracy and efficiency of the test;

After exporting the sampling data, you can observe the knife rod vibration waveform and read the amplitude. In the operation interface, you can zoom in on the waveform and observe the local waveform;

[0043] During this process, the ultrasonic tool rod vibrates, and the position of the light spot reflected by its end face vibrates accordingly. At this time, the displacement sensor converts the position of the light spot into an electrical signal output.

[0044] When the above-mentioned high-precision tool rod testing system is used, it is possible to measure the longitudinal amplitude of the ultrasonic tool head and detect whether the ultrasonic tool rod is qualified. It is also possible to adjust the test module in the vertical direction so that the light reflected by the ultrasonic tool rod in a static state can fall to the center of the receiving screen and form a light spot, thereby zeroing it, ensuring that the receiving screen can receive the reflected light spot in subsequent testing processes, thereby improving the accuracy and efficiency of the test.
