[0003] The existing problems are: 1. In high-speed machining equipment, the collection area is not perfectly protected, and when rotating at high speed, a large centrifugal force will be generated, which will likely damage the stability of signal collection; 2.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0024] like Figure 1 and Figure 2 As shown, this embodiment discloses a machining tool holder, including a tool holder shaft 100, a housing 200, a signal monitoring module 300, an elastic filler 400, and a power supply module 500;

[0025] like Figure 3 As shown, the upper end of the tool holder shaft 100 can be connected to the spindle 710 of the machining equipment, and the lower end can be connected to any type of execution tool, such as a machining tool or a friction welding stirring head. The tool holder shaft 100 has a variable diameter section in the middle, which has a certain length along the axial direction. The outer diameter of this variable diameter section is smaller than the outer diameter of other positions of the tool holder shaft 100. The variable diameter section is configured as the thinnest end of the tool holder shaft 100. In this embodiment, the signal monitoring module 300 monitors the strain fluctuation at the position of this variable diameter section to achieve synchronous visualization of the strain signals (pressure, torque, lateral force, and side force) during the machining process.

[0026] like Figure 2 and Figure 3 As shown, the housing 200 is coaxially arranged with the tool holder shaft 100, and the housing 200 surrounds the variable diameter section circumferentially. The housing 200 and the tool holder shaft 100 have a radial distance at their outer peripheries. The magnitude of this radial distance can be selected according to actual conditions. This radial distance is used to accommodate the signal monitoring module 300 and the elastic filler 400. In some preferred embodiments, the housing 200 and the tool holder shaft 100 are detachably connected for easy assembly and disassembly. In this embodiment, the housing 200 and the tool holder shaft 100 are detachably connected by multiple screws. When the tool holder shaft 100 rotates, the housing 200 can rotate together with the tool holder shaft 100.

[0027] like Figure 3As shown, the signal monitoring module 300 is mounted on the tool holder shaft 100. The signal monitoring module 300 can collect strain information from the tool holder shaft 100 and send it to an external host computer (not shown). In this embodiment, the signal monitoring module 300 includes a strain monitoring element 310 and a signal acquisition board 320, both disposed within the housing 200. The strain monitoring element 310 is attached to the outer periphery of the variable diameter section of the tool holder shaft 100. To monitor different strain types, the strain monitoring element 310 can use various bridging methods, sizes, and types of strain gauges to acquire signals of pressure, torque, lateral force, and side force of the tool holder shaft 100. The specific bridging method, bonding angle, and strain gauge model parameters are not limited in this embodiment. In some preferred embodiments, adhesive is used to bond the strain monitoring element 310 to the variable diameter section of the tool holder shaft 100 and compact it to ensure linear deformation testing. The bonding method and adhesive used are also considered. The type of water is not limited; the signal acquisition board 320 is electrically connected to the strain monitoring device 310 through wires. When the strain monitoring device 310 detects deformation, it will collect strain information such as pressure, torque, lateral force and side force through the signal acquisition board 320, and process the data information simultaneously. Finally, it will be sent to the PC or PLC. The data can be presented as a high-frequency digital signal transmitted to the host computer software in the form of scatter points or curves, or it can be transmitted to the machining equipment in the form of analog quantities (voltage or current). The above two modes allow users to monitor the pressure, torque, lateral force and side force information of the tool holder shaft 100 in real time, and will promote the closed-loop control of data monitoring.

[0028] like Figure 3As shown, the elastic filler 400 is disposed between the outer peripheral surface of the tool holder shaft 100 and the inner peripheral surface of the housing 200. Specifically, the elastic filler 400 is densely filled between the outer peripheral surface of the tool holder shaft 100 and the inner peripheral surface of the housing 200, and the elastic filler 400 can also serve as a connecting part, tightly connecting the tool holder shaft 100 and the housing 200 together. In this embodiment, since the signal monitoring module 300 is disposed inside the housing 200, at least a portion of the elastic filler 400 is disposed between the housing 200 and the signal monitoring module 300, and the elastic filler 400 wraps around the outer periphery of the signal monitoring module 300. In some preferred embodiments, the elastic filler 400 wraps the strain monitoring element 310 (strain gauge) attached to the tool holder shaft 100 around the tool holder shaft 100, and the elastic filler 400 also completely wraps the signal acquisition plate 320 located inside the housing 200, thereby fixing the position of the signal acquisition plate 320. In this embodiment, the elastic filler 400 is made of an elastic material, such as silicone, rubber, fluororubber, or other soft rubber materials. The elastic filler 400 is a variety of soft rubber materials that can be used to seal the signal acquisition board 320 inside the housing 200 to avoid the large centrifugal force generated when rotating at high speed affecting the stable acquisition of data. The elastic filler 400 not only protects the circuit of the signal acquisition board 320, but also enhances heat dissipation.

[0029] like Figure 3As shown, the power supply module 500 includes a first magnet 510, a first coil 520, a rectifier and voltage regulator assembly 530, and a battery 540. The first magnet 510 is fixedly mounted on the external structure. The first coil 520 is coaxially mounted on the lower end of the housing 200. The first coil 520 can rotate with the housing 200, and the first coil 520 and the first magnet 510 can achieve electromagnetic induction cooperation, thereby generating an induced electromotive force and alternating current when the first coil 520 rotates, cutting the magnetic field. The rectifier and voltage regulator assembly 530 is disposed inside the housing 200 and is electrically connected to the first coil 520 through wires. The current output by the first coil 520 will pass through the rectifier and voltage regulator assembly 530. The rectifier and voltage regulator assembly 530 includes a rectifier bridge, a filter, and a voltage regulator chip, etc. Referring to existing technologies, the function of this device is to rectify, filter, and regulate the output current. Specifically, the rectifier bridge converts low-voltage AC power into DC current; the filter filters the DC current; the filtered current still has some fluctuations, but the voltage regulator chip can stabilize the current and voltage within a range suitable for subsequent modules. Therefore, the rectifier and regulator component 530 outputs a stable DC voltage below 12V, which is connected to the battery 540 via a wire. The battery 540 is housed within the housing 200 and is electrically connected to and powers the signal acquisition board 320 via a wire. This allows the signal acquisition board 320 to provide stable power for the synchronous high-frequency acquisition of multiple signals (process signals such as pressure, torque, lateral force, and side force). This embodiment, by acquiring process signals through the signal acquisition board 320, enhances the intelligent function of the machining tool holder, enabling online monitoring. This provides convenience for users to monitor the machining process, optimize machining parameters in real time, and improve machining production quality and efficiency.

[0030] like Figure 3 As shown, in some preferred embodiments, the elastic filler 400 simultaneously wraps around the outer periphery of the rectifier and voltage regulator assembly 530, securing the rectifier and voltage regulator assembly 530 within the housing 200. The elastic filler 400 provides protection and enhances heat dissipation for the rectifier and voltage regulator assembly 530, while also securing it within the housing 200. Simultaneously, the elastic filler 400 also wraps around the outer periphery of the battery 540, further protecting it and enhancing heat dissipation.

[0031] like Figure 3 As shown, in some preferred embodiments, the power supply module 500 also includes a power display screen 550 disposed on the housing 200. The power display screen 550 is exposed on the outside of the housing 200, and the battery 540 is electrically connected to the power display screen 550, so that external personnel can easily check the power status of the battery 540.

[0032] like Figure 3As shown, in some other preferred embodiments, the machining tool holder further includes a discharge module 600; the discharge module 600 includes a second magnet 610 and a second coil 620; the second magnet 610 is coaxially fixed on the outer periphery of the housing 200, and the second magnet 610 can rotate with the housing 200; the second coil 620 is fixedly disposed on the external structure, and the second magnet and the second coil 620 can cooperate with electromagnetic induction. Based on the principle of electromagnetic induction, the current in the second coil 620 generates a constant magnetic field when the magnetic pole rotates, realizing efficient energy conversion and outputting alternating current, which can be used as a power source for other mechanical equipment.

[0033] like Figure 4 As shown, this embodiment also discloses a machining equipment, which includes a machining equipment body 700, an execution tool 800, and a machining tool holder, as detailed below:

[0034] The machining equipment body 700 has a high-speed rotating spindle 710. The tool holder shaft 100 of the machining tool holder is connected to the spindle 710. In this embodiment, the upper end of the tool holder shaft 100 is connected to the spindle 710. In some preferred embodiments, the upper end of the tool holder shaft 100 is connected to the spindle 710 by a pull stud 720. The lower end of the tool holder shaft 100 is connected to the execution tool 800. The execution tool 800 includes a friction welding stirring head (i.e., a component for performing friction welding) or a drill bit. In this embodiment, the execution tool 800 includes a friction welding stirring head, which is connected to the tool holder shaft 100 of the machining tool holder by an existing locking mechanism.

[0035] like Figure 4 As shown, in this embodiment, a first retainer 730 and a second retainer 740 are respectively provided on both sides of the machining equipment body 700. One end of the first retainer 730 is fixedly connected to the first magnet, and one end of the second retainer 740 is fixedly connected to the first coil 520.

[0036] In some preferred embodiments, the signal acquisition board 320 of the signal monitoring module 300 is connected to the host computer via wired or wireless means, and the host computer is connected to the machining equipment body 700. In this embodiment, the data acquired by the signal acquisition board 320 is presented in the host computer software in the form of scatter plots or curves. At the same time, it can also be transmitted to the machining equipment body 700 in the form of analog quantities (voltage or current), so that the user can monitor the pressure, torque, lateral force and side force on the tool holder in real time, and promote closed-loop control of data monitoring.

[0037] The machining equipment in this embodiment can replace tool holders of various types and sizes, improving its versatility; the power supply module can stably and in real time supply power to the collected strain information, effectively improving the accuracy and stability of the acquisition; the machining equipment can monitor the process signals of various strain types in real time through the host computer, and can stably monitor them with high frequency and high precision in real time, improving the visualization of the machining process and making it easy for users to adjust the machining parameters in a timely manner, greatly improving the machining quality of the components.
