[0002] During the cutting process, it is often difficult to accurately control the machining process due to the lack of real-time monitoring of the vibration parameters between the tool and the workpiece. In order to solve these problems, a type of vibration measuring tool holder that can realize online monitoring of the machining process has gradually emerged. The vibration information of this type of tool holder is used to determine whether the machining process is proceeding normally, adjust the tool machining parameters in real time, evaluate and predict the tool status, and optimize and improve the machining process. It plays a key role in achieving efficient, accurate and reliable machining operations. However, due to the high price of the product, it is often used in experimental research rather than in actual product processing.

The longitudinal section of the magnet 6 is arc-shaped.
[0026] Implementation method of the electromagnetic induction self-powered device of the present invention:
[0027] The intelligent tool handle self-powering device of the present invention is as follows Figure 3-4As shown. This method is based on Faraday's law of electromagnetic induction. The specific implementation method is to use a magnet bracket 5 to carry a magnet 6 to generate a constant magnetic field near the lower end of the spindle 15. The magnet bracket 5 is connected to the spindle 15 through the screw hole on the spindle cover by screws 501. The magnet bracket 5 is manufactured by 3D printing of white resin material, and the magnet 6 is a customized NdFeB strong magnet with a circular arc shape in the longitudinal section. At the same time, a tapered handle annular hole 103 distributed at 120° is set on the handle body 1 for embedding three copper coils 7 placed at 120°. When the machine tool is cutting, the copper coil 7 rotates with the handle body 1. At this time, the magnetic flux in the copper coil 7 changes with the rotation, and the changing magnetic flux will generate an induced potential. The copper coil 7 passes through the coil lead hole 104 and then is collected through the circuit board lead hole 106 to the power management board 12. After rectification and voltage stabilization, it supplies power to various circuits and components; the circuit schematic diagram of the power management board 12 is shown in the attached Figure 7As shown, the circuit includes 6 circuit board lead interfaces P15, capacitors C94~C97, C99~C100, C103~C105, resistors R116~R123, temperature measuring resistor RT1, LED lamp D6 and wireless power receiver U13; the circuit board lead interface P15 includes 6 interfaces; the wireless power receiver U13 includes interfaces CLAMP1, COMM1, AC1, AC2, BOOT1, BOOT2, CLAMP2, COMM2, OUT, CHG, ILIM, FOD, RECT, T S, EN1, EN2; one end of the capacitor C96 is connected in parallel with the capacitors C99 and C103 and connected to the AC1 interface of U13, and the other end of C96 is connected to the BOOT1 of U13; the other end of the capacitor C99 is connected to the interface CLAMP1 of U13; the other end of the capacitor C103 is connected to the interface COMM1 of U13; one end of the capacitor C97 is connected in parallel with the capacitors C100 and C104 and connected to the AC2 interface of U13, and the other end of C97 is connected to the BOOT2 of U13; the other end of the capacitor C100 is connected to the interface CLAMP2 of U13; The other end of capacitor C104 is connected to the interface COMM2 of U13; the positive pole of the LED lamp D6 is connected to the interface OUT of U13, and the negative pole is connected to the interface CHG of U13; one end of the resistor R116 is connected to the interface ILIM of U13, and the other end is connected to the resistors R117 and R121, and the interface FOD of U13; one end of the resistor R117 is connected to the interface FOD of U13, and the other end is connected to the interface RECT of U13 and the filter capacitor C105; one end of the resistor R121 is connected to the interface FOD of U13, and the other end is connected to GND; one end of the capacitor C105 is connected to RECT of U13, and the other end is connected to GND; one end of the resistor R119 is connected to VOUT, and the other end is connected to resistor R122 and interface 5 of P15, and the other end of resistor R122 is connected to GND; one end of the resistor R120 is connected to VOUT, and the other end is connected to resistor R123 and interface 6 of P15, and the other end of resistor R123 is connected to GND; the temperature measuring resistor RT1 is connected to interface TS of U13; interfaces 1 and 2 of P15 are connected to GND, interfaces 3 and 4 are connected to voltage source VOUT, interface 5 is connected to interface EN1 of U13, and interface 6 is connected to interface EN2 of U13.
[0028] When the generated induced voltage is delivered to the circuit through the copper coil 7, the internal synchronous rectifier feeds the voltage to the RECT pin with filter capacitor C105; BQ51013 identifies and authenticates itself by switching the COM FET on and off, and by switching CCOMM on and off. If the authentication is successful, the transmitter will remain powered on;
[0029] The EN1 and EN2 pins include internal 200 kΩ pull-down resistors, so if these pins are not connected, the wireless power receiver BQ51013 will default to AD-EN control mode;
[0030] However, these pins can be pulled high, as shown by resistors R119 and R120;
[0031] The BQ51013 provides two identical integrated communication FETs connected to pins COMM1 and COMM2. These FETs are used to modulate the secondary load current, enabling the BQ51013 to transmit error control and configuration information to the transmitter.
[0032] In addition to resistive load modulation, the BQ51013 is also capable of capacitive load modulation, as shown in the circuit on the left;
[0033] In this case, the capacitor is connected from COMM1 to AC1 and from COMM2 to AC2;
[0034] When the COMM switch is closed, a 22nF capacitor is actually connected between AC1 and AC2;
[0035] Connecting a capacitor between AC1 and AC2 modulates the impedance seen by the coil, which will be reflected in the primary resistance as a change in current.
[0036] Three-way vibration measurement implementation method of the present invention:
[0037] The intelligent tool handle three-way vibration measuring device of the present invention is as shown in the attached Figure 5-7As shown. It includes a vibration carrier shaped groove 1002, a vibration carrier center through hole 1003, a vibration carrier mounting hole 1004, and a vibration plate lead square hole 108; the method is based on the MEMS accelerometer connected to the tool handle body 1 through the vibration measurement carrier 10 to achieve three-dimensional vibration measurement of the tool handle. The specific implementation method is to build a vibration measurement board 9 with the ADXL359 three-axis accelerometer as the core. The overall shape of the vibration measurement board is formed by the intersection of a circle and a straight edge, and the accelerometer is set on the front of the center of the board; the vibration plate carrier 10 is provided with a vibration carrier shaped groove 1002, which is formed by the intersection of a circle and a straight edge, and is used to match the outer contour of the vibration measurement board 9; A vibration measuring plate mounting hole 1001 is provided on the opposite side of the groove-shaped straight edge of the vibration plate carrier 10, and the vibration measuring plate 9 and the vibration plate carrier 10 are matched through the vibration carrier special-shaped groove 1002 and connected by threads; vibration carrier mounting holes 1004 are provided around the vibration plate carrier 10, and the vibration carrier mounting holes 1004 are respectively connected with the axis of the screw holes set on the cutting plane of the handle, and the vibration plate carrier 10 is connected to the handle body 1 through threads; a wiring socket is provided on one side of the straight edge of the vibration measuring plate 9, and the vibration measuring plate 9 is connected to the circuit on the surface of the handle through the wiring socket through the vibration plate lead square hole 108 set at the bottom of the cutting surface of the handle. When the tip of the knife vibrates, the vibration measuring plate 9 with the accelerometer as the core will vibrate accordingly, thereby measuring and obtaining a three-axis vibration signal.
[0038] The circuit diagram of the vibration measurement board is as attached. Figure 8 As shown, the ADXL359 chip has a reference coordinate system inside. When the chip moves with the tool handle, the coordinates of the chip rotate relative to the reference coordinate system. The chip will record the difference and output an angular velocity after processing.
[0039] The upper left part is a voltage filtering and rectifying circuit to ensure that the voltage of the ADXL359 chip is stable and works within the normal range. An LC filtering circuit is used, and the voltage VCC is connected in series with the inductor L4 and then connected to the ground in parallel with capacitors C32 and C33, and Vs is directly grounded through capacitors C32 and C33 filtering. P7 is responsible for connecting the vibration plate with the main control board so that the main control board can transmit signals and control the vibration plate chip U7. Interfaces 7, 8, 9, and 10 on P7 are connected to 1, 2, 3, and 4 on U7, and a resistor R44 is connected in series with the interface ACC_MISO to play an impedance matching role, reduce reflections, avoid oscillation, and ensure the normal operation of the circuit. P8 and P9 are responsible for collecting the temperature signal of the vibration plate and are connected to the thermocouple circuit of the main control board. Since the three-way vibration measuring device of the present invention is located below the handle of the knife near the point vibration source of the knife tip, a more significant vibration signal can be obtained.

For those skilled in the art, any obvious changes made thereto without departing from the principles and spirit of the present invention should be considered to be included in the scope of protection of the claims of the present invention.
