Embodiment 1

[0078]The emitter of the laser displacement sensor, as well as the ultrasonic sensor, are placed on the surface of the shell, and can measure the distance between it and the end face of the emitter and the ultrasonic signal at any time. The measured data are sent to the processor module for accumulation and calculation. The calculation result (that is, the amplitude value) is sent to a display module (such as an LED display screen) for the operator to read. The LED display can be flipped up or rotated for easy reading by the operator. The processor module continuously performs data comparison and judgment. When stable and credible amplitude measurement data is finally obtained, an audible and visual alarm signal is output to inform that the test has been completed. At the same time, the measuring instrument can also store and output amplitude data. The operator can take a reading and stop the measurement. You can also continue to measure without turning off the power. The...

Embodiment 2

[0080] In addition to the laser amplitude measuring instrument, it can also be connected to the upper industrial computer or intelligent control terminal in a wired or wireless way through a wired communication module or a wireless communication module. The intelligent control terminal is a smart phone, a tablet computer or a controller with an interactive interface. Taking a smart phone as an example, as the functions of control, display and data storage, its functions are realized by the pre-installed APP. The actual operation and measurement process is basically the same as the previous example. The operator can read on the intelligent control terminal and stop the measurement. The test data is saved on the intelligent control terminal and can be read at any time.

Description

technical field [0001] The invention relates to a measurement technology for ultrasonic equipment, in particular to a laser amplitude measuring instrument for ultrasonic equipment and a measurement method thereof. Background technique [0002] The vibration frequency of ultrasonic equipment is generally 15kHz---100kHz, and the amplitude (peak-to-peak value) is tens of microns. The amplitude is in the form of a continuous change of a sinusoidal function, and the maximum amplitude usually does not exceed 200 microns. In the design and use of ultrasonic tools, the maximum value of the amplitude (referred to as peak-to-peak amplitude) is a key indicator. However, due to the extremely high frequency and changing speed of ultrasonic equipment, the absolute value of the amplitude is very small, which makes it difficult to measure the amplitude. [0003] There are many existing measurement methods. Measurements can be made using laser interferometers, which have the advantage tha...
