[0002] Ultra-high speed CNC machine tools are modern manufacturing equipment that use advanced CNC technology to perform precision machining at cutting speeds, feed rates, and accelerations far exceeding those of traditional machine tools. Their core features are the combination of high-speed spindles, fast-response servo systems, high-rigidity structures, and intelligent control technology, which significantly improves machining efficiency and accuracy, and are especially suitable for machining high-hardness materials or complex parts.

[0003] When cutting tools experience excessive wear, chipping, or other failures, not only will the machined parts be scrapped, but it may also cause problems such as machine tool vibration and impact. In severe cases, it may even damage critical components such as the machine tool spindle, resulting in huge economic losses and production delays. Therefore, real-time, accurate, and reliable monitoring of the lifespan of cutting tools for ultra-high-speed CNC machine tools, timely warning of tool wear status, and prompting for replacement are important links to ensure production continuity, improve product quality, and reduce production costs.

[0004] Existing monitoring devices mostly use fixed-installation sensors. When a sensor malfunctions or needs to be replaced, the disassembly process is complex, requires specialized tools, and is time-consuming, severely impacting equipment maintenance efficiency. Furthermore, the ultra-high-speed machining environment generates a large amount of metal shavings, oil, and other impurities. These impurities easily adhere to the sensor surface, and if not cleaned promptly, they can lead to decreased sensor detection accuracy or even misjudgments. In addition, the sensor positions in existing monitoring devices are usually fixed, making it difficult to flexibly adjust their height according to different tool sizes and machining requirements. This results in incomplete coverage of tool wear monitoring and poor applicability. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, according to Figures 1-7 As shown, a tool life monitoring device for an ultra-high-speed CNC machine tool includes a CNC machine tool body 1, a machining center 2 is provided inside the CNC machine tool body 1, a tool body 3 is provided at the bottom of the machining center 2, a monitoring component 4 is installed on the outer wall of the machining center 2, and a cleaning component 5 is provided inside the monitoring component 4.

[0028] The monitoring component 4 includes a housing 401, the outer wall of which is fixedly connected to the outer wall of the machining center 2. The inner wall of the housing 401 has symmetrically formed grooves 402. A moving block 403 is slidably connected to the inner wall of the grooves 402. A connecting member 404 is rotatably connected to the bottom of the moving block 403 via a bearing. A mounting groove 405 is symmetrically formed on the top of the connecting member 404. A mounting block 406 is engaged inside the mounting groove 405. A slot 407 is formed on the outer wall of the mounting block 406. A laser displacement sensor 408 is fixedly connected to the bottom of the mounting block 406. A fixing plate 409 is fixedly connected to the top of the mounting block 406. A sliding column 410 is symmetrically slidably connected to the inner wall of the fixing plate 409. A spring 411 is sleeved on the outer wall of the sliding column 410. A locking block 412 is fixedly connected to the outer wall of the sliding column 410. The outer wall of the locking block 412 slidably engages with the inner wall of the slot 407. Next, a cleaning component is provided on the inner wall of the outer casing 401. One end of the spring 411 is fixedly connected to the outer wall of the locking block 412, and the other end of the spring 411 is fixedly connected to the outer wall of the fixing plate 409. A cylinder 41 is installed on the top of the outer casing 401. The output end of the cylinder 41 penetrates the outer casing 401 and is fixedly connected to the top of the moving block 403. A motor 413 is installed on the outer wall of the moving block 403. The output end of the motor 413 penetrates the motor and is fixedly connected to the outer wall of the connector 404. Sliders are symmetrically fixedly connected to the outer wall of the moving block 403. The outer wall of the slider is slidably connected to the inner wall of the slide groove 402. The cleaning component includes a magnet 414 fixedly installed at the bottom of the inner wall of the outer casing 401. A cleaning plate 415 is magnetically connected to the outer wall of the magnet 414. The shell of the cleaning plate 415 is made of steel, and the contact surface between the cleaning plate 415 and the laser displacement sensor 408 is made of non-woven fabric.

[0029] The overall effect of Embodiment 1 is as follows: the monitoring component 4 can achieve accurate and flexible monitoring of the wear condition of the tool body 3, and facilitates the installation and maintenance of the laser displacement sensor 408. The housing 401 provides a stable installation base for the entire component. The sliding groove 402 on its inner wall cooperates with the moving block 403. Driven by the cylinder 41, it can drive the laser displacement sensor 408 to smoothly adjust its horizontal position, ensuring that the sensor can be aligned with different monitoring points of the tool. The motor 413 drives the connecting part 404 to rotate, so that the laser displacement sensor 408 can flexibly adjust the monitoring angle, further improving the comprehensiveness of the monitoring. Regarding the installation of the laser displacement sensor 408... The mounting block 406 and the mounting groove 405 have a snap-fit ​​structure, which, together with the sliding column 410, spring 411 and locking block 412 on the fixing plate 409, enables quick installation and removal of the sensor. When installing, the spring force of the spring 411 causes the locking block 412 to snap into the slot 407, ensuring that the sensor is installed firmly. When replacement or maintenance is required, the sliding column 410 can be pulled to release the locking block 412 from the slot 407, which is convenient to operate. In addition, the cleaning plate 415 attracted by the magnet 414 in the cleaning component can wipe the surface of the laser displacement sensor 408 during its movement. Together with the cleaning component 5, it ensures the cleanliness of the sensor and ensures the accuracy of the monitoring data.

[0030] Example 2, according to Figure 7 As shown, the cleaning component 5 includes a miniature air pump 501 symmetrically screwed onto the outer wall of the laser displacement sensor 408. The air outlet of the miniature air pump 501 is fixedly connected to a connecting pipe 502. The outer wall of the connecting pipe 502 is fixedly connected to a miniature nozzle 503. A support frame 504 is symmetrically attached to the outer wall of the laser displacement sensor 408. The outer wall of the support frame 504 is fixedly connected to the connecting pipe 502. The air inlet of the miniature air pump 501 is fixedly connected to an air inlet pipe 505.

[0031] The overall effect of embodiment 2 is as follows: the cleaning component 5 can effectively ensure the monitoring accuracy of the laser displacement sensor 408. The micro air pump 501 is installed on the outer wall of the laser displacement sensor 408 by screws. During operation, it draws in air through the air inlet pipe 505 and then delivers it to the micro nozzle 503 through the connecting pipe 502. The micro nozzle 503 can accurately spray air onto the monitoring surface of the laser displacement sensor 408, thereby quickly removing dust, debris and other impurities attached to the monitoring surface. At the same time, the support frame 504 provides stable support and fixation for the connecting pipe 502, ensuring stability during the air spraying process. Through air spraying cleaning, the interference of impurities on the laser signal is avoided, allowing the laser displacement sensor 408 to always maintain a clear and accurate monitoring state.

[0032] The working principle of the entire device is as follows: First, after the monitoring component 4 is started, the cylinder 41 operates, and its output end drives the moving block 403 to slide in the slide groove 402 on the inner wall of the outer shell 401. The slider on the outer wall of the moving block 403 cooperates with the slide groove 402 to ensure stable movement. This causes the connecting piece 404 and the laser displacement sensor 408 at the bottom of the connecting piece 404, which are rotatably connected by bearings at the bottom of the moving block 403, to move accordingly, thereby adjusting the horizontal position of the laser displacement sensor 408. At the same time, the motor 413 operates, and its output end drives the connecting piece 404 to rotate, which can adjust the monitoring angle of the laser displacement sensor 408 so as to accurately align it with the tool body 3.

[0033] The laser displacement sensor 408 is snapped into the mounting groove 405 on the top of the connector 404 by the mounting block 406. During installation, the mounting block 406 is placed into the mounting groove 405. The sliding column 410 on the inner wall of the fixing plate 409 drives the locking block 412 to engage with the locking groove 407 on the outer wall of the mounting block 406 under the elastic force of the spring 411, thus achieving a stable installation of the laser displacement sensor 408. When it needs to be replaced, the sliding column 410 is pulled to disengage the locking block 412 from the locking groove 407 and it can be removed. The stable installation of the laser displacement sensor 408 can monitor the wear of the tool body 3 in real time and reflect its wear degree by detecting the displacement change of the tool.

[0034] During the monitoring process, the cleaning component and the cleaning assembly 5 work together to ensure the monitoring accuracy of the laser displacement sensor 408. In the cleaning component, the magnet 414 at the bottom of the inner wall of the outer shell 401 magnetically fixes the steel cleaning plate 415. When the laser displacement sensor 408 moves, the non-woven fabric contact surface of the cleaning plate 415 can wipe and clean its surface. The micro air pump 501 of the cleaning assembly 5 operates, intakes air through the air inlet pipe 505, and then delivers it to the micro nozzle 503 through the connecting pipe 502. The micro nozzle 503 sprays air onto the monitoring surface of the laser displacement sensor 408 to remove attached dust and other impurities. The support frame 504 provides support and fixation for the connecting pipe 502.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
