Description

Technical Field

[0001] This invention relates to the field of machining condition monitoring technology, specifically to a cutter ring device and milling cutter assembly for monitoring milling vibration. Background Technology

[0002] In precision cutting, cutting vibration is a key factor affecting the surface quality, tool life and machine tool accuracy. Real-time monitoring of vibration during milling is essential for process optimization, preventive maintenance and adaptive control.

[0003] Currently, vibration monitoring solutions are mainly divided into several categories: machine tool body-mounted sensors, workpiece-mounted sensors, rotary telemetry systems, and intelligent tool holders.

[0004] Specifically, in the solution of installing sensors on the machine tool body, the accelerometer is usually installed in the spindle box, worktable and other positions. Although this method is simple to install, the signal transmission path is long and it is easily affected by other vibration sources of the machine tool. The detection sensitivity is low and it cannot directly reflect the true state of the tool-workpiece contact point. In the workpiece-mounted sensor solution, the sensor is usually mounted on the workpiece or fixture. This method has problems such as indirect signal and large interference, and is limited by the shape of the workpiece and clamping, so its versatility is poor. In rotary telemetry systems, a transmitter module is typically installed on the rotary spindle to transmit data via telemetry. This system is costly, complex to install, and usually has low integration, making it difficult to deploy quickly on various tool holders. In smart toolholder solutions, sensors are usually integrated inside the toolholder. Although this method can directly monitor the tool and has high signal fidelity, it requires modification of the toolholder structure, which is extremely costly. Furthermore, the lifespan of the sensor is tied to that of the toolholder, resulting in insufficient flexibility.

[0005] Therefore, designing a vibration monitoring solution that is easy to install, provides accurate signals, and is cost-effective without altering the original mechanism of the machine tool and tool holder is a technical problem that urgently needs to be solved. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of current tool vibration monitoring solutions by providing a tool ring device and milling cutter assembly for milling vibration monitoring, which achieves convenient installation, accurate signal, and moderate cost without altering the original structure of the machine tool and tool holder.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solution: A tool ring device for monitoring milling vibration includes an inner flange conical ring, an elastic wedge ring, and a rigid outer sleeve. Both the inner flange conical ring and the elastic wedge ring are open-loop structures. The elastic wedge ring is elastic and has a wedge-shaped cross-section. The inner conical ring of the flange is used to be fitted onto the milling cutter holder. An elastic wedge ring and a rigid outer sleeve are fitted on the outer side of the inner conical ring of the flange in sequence. The inner conical ring of the flange and the rigid outer sleeve are connected by bolts. The rigid outer sleeve and the inner conical ring of the flange cooperate to apply pressure to the elastic wedge ring, so that the elastic wedge ring applies a lateral force pointing towards the central axis of the inner conical ring and a vertical force parallel to the central axis of the inner conical ring. The rigid outer casing is used to assemble circuit boards, which include a sensing and signal conditioning board, a main control and data processing board, a wireless communication board, a power management board, a battery board, and an interface and charging board.

[0008] As a preferred technical solution of this application, it also includes a blade ring housing, which is cylindrical and is used to engage with the inner conical ring of the flange. When the blade ring housing engages with the inner conical ring of the flange, the top of the blade ring housing abuts against the rigid outer sleeve, and the blade ring housing, the rigid outer sleeve, and the inner conical ring of the flange cooperate to form a first chamber, in which the circuit board is located.

[0009] As the preferred technical solution of this application, the rigid outer sleeve has a first groove and a second groove, a first movable plate is slidably disposed in the first groove, a pushing component is disposed in the second groove, and a first spring is connected between the first movable plate and the pushing component, the first spring being elastic; The elastic wedge ring includes a thick end and a thin end, the thickness of the thick end being greater than the thickness of the thin end, and the pushing component is used to abut against the thick end of the elastic wedge ring; When the rotational speed of the milling cutter holder increases, under the action of centrifugal force, the first movable plate can move relative to the first slide groove in a direction away from the central axis of the rigid outer sleeve, and the first spring is stretched. The stretched first spring can pull the pushing assembly to increase the contact force between the pushing assembly and the thick end of the elastic wedge ring.

[0010] As the preferred technical solution of this application, the pushing component includes a first abutment block and a second abutment block, the second slide groove includes a second main slide groove and a second auxiliary slide groove, the length direction of the second main slide groove is perpendicular to the length direction of the second auxiliary slide groove, the length direction of the second main slide groove is in the same direction as the length direction of the first slide groove, the first abutment block is located in the second main slide groove, the second abutment block is located in the second auxiliary slide groove, the first abutment block is used to connect with the first spring, and the second abutment block is used to abut against the thick end; The first abutment has a first inclined portion, and the second abutment has a second inclined portion. The first inclined portion is used to abut against the second inclined portion. When the force of the first spring pulling the first abutment increases, the first abutment can move along the length direction of the second main slide groove. Under the guidance of the action of the first inclined portion and the second inclined portion abutting against each other, the second abutment can move along the length direction of the second auxiliary slide groove to increase the contact force between the second abutment and the thick end.

[0011] As the preferred technical solution of this application, the length direction of the first groove is perpendicular to the central axis of the rigid jacket.

[0012] As the preferred technical solution of this application, the first movable plate is provided with a first air passage and a second air passage. The first air passage and the second air passage are symmetrically arranged about the central axis of the first movable plate. One end of the first air passage extends to the side wall of the first movable plate and the other end is connected to the first slide groove. One end of the second air passage extends to the other side wall of the first movable plate and the other end is connected to the first slide groove. The opening on the first air passage extending to the side wall of the first movable plate is the first opening, and the opening on the second air passage extending to the side wall of the first movable plate is the second opening. When the milling cutter performs climb milling, the opening direction of the first opening is in the same direction as the rotation direction of the rigid sleeve, and the opening direction of the second opening is opposite to the rotation direction of the rigid sleeve. The rigid outer casing is provided with a third air passage, which is used to connect the first chamber and the first slide groove; When the milling cutter holder is not rotating, the first movable plate retracts into the first slide groove; When the milling cutter holder rotates, under the action of centrifugal force, the first movable plate can extend out of the first slide groove, and the first opening and the second opening can extend out of the first slide groove.

[0013] As the preferred technical solution of this application, the first movable plate includes a movable plate body and an adjustment knob. The first air passage and the second air passage are disposed on the movable plate body. The adjustment knob is threadedly connected to the movable plate body. The adjustment knob is connected to the first spring. The length direction of the adjustment knob, the length direction of the first movable plate, and the length direction of the first slide groove are in the same direction.

[0014] As the preferred technical solution of this application, the rigid outer sleeve is provided with a plurality of first sliding grooves, and the number of the first movable plate, the first spring and the pushing component are adapted to the number of the first sliding grooves.

[0015] As the preferred technical solution of this application, six planes are formed on the outer side wall of the rigid jacket, and the six planes are distributed around the central axis of the rigid jacket, and the circuit board is mounted on the planes.

[0016] The present invention also provides a milling cutter assembly, including a cutter ring device for monitoring milling vibration as described above, and a milling cutter shank body, wherein the cutter ring device is used to be mounted on the side wall of the milling cutter shank body.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the scheme of this application, during the process of installing the cutter ring device on the milling cutter holder, the rigid outer sleeve is first placed on the milling cutter holder, then the elastic wedge ring is placed on the milling cutter holder, and then the flange inner conical ring is placed on the milling cutter holder, so that the elastic wedge ring is sandwiched between the flange inner conical ring and the rigid outer sleeve. Bolts are then used to connect the flange inner conical ring and the rigid outer sleeve. Specifically, the inner wall of the rigid outer sleeve is cylindrical, the outer wall of the elastic wedge ring is cylindrical, and the inner wall has an inner conical surface structure. The cone angle α corresponding to the inner conical surface is typically between 5° and 15°, preferably 8°. The outer wall of the inner conical ring, which contacts the inner wall of the elastic wedge ring, has an outer conical surface structure. The cone angle of the outer conical surface on the flange inner conical ring matches the cone angle of the inner conical surface on the elastic conical ring, meaning their cone angles are equal or close. This improves the fit between the flange inner conical ring and the elastic wedge ring during mating. Simultaneously, the inner wall of the flange inner conical ring is cylindrical to fit against the outer wall of the milling cutter shank. Furthermore, the thinner end of the elastic wedge ring inserts into the area between the flange inner conical ring and the rigid outer sleeve before the thicker end. Thus, during mating between the rigid outer sleeve and the flange inner conical ring... When pressure is applied to the elastic wedge ring, the elastic wedge ring can apply a lateral force pointing towards the central axis of the inner cone ring of the flange and a vertical force parallel to the central axis of the inner cone ring. Since both the inner cone ring and the elastic wedge ring are open-loop structures, the lateral force causes the inner cone ring to deform, making it more securely clamped to the milling cutter shank, and ensuring a stronger fit between the inner wall of the inner cone ring and the outer wall of the optical axis section of the milling cutter shank. Furthermore, in this application, based on the sidewall of the inner cone ring with its open-loop structure... Under pressure, the inner conical ring of the flange can bend and deform, thus changing the diameter of the cylindrical structure corresponding to the inner wall of the inner conical ring. This allows the tool ring device of this application to be adapted to tool holders with various optical shaft sections of different diameters, further improving the compatibility between the tool ring device and the milling cutter holder. Without modifying the existing tool holder and machine tool, the tool ring device of this application can be installed on the optical shaft of the existing milling cutter holder to monitor the vibration state of the milling process in real time. In this way, without changing the original structure of the machine tool and tool holder, it can achieve the goals of convenient installation, accurate signal, and moderate cost. 2. Furthermore, by setting a first movable plate, a first spring, and a pushing assembly, when the milling cutter changes from a stopped state to a working state, the milling cutter shank changes from a stationary state to a rotating state. Under the action of centrifugal force, the first movable plate can move relative to the first slide groove in a direction away from the central axis of the rigid outer sleeve, and stretch the first spring. After being pulled by the first movable plate, the first spring can pull the pushing assembly, thereby increasing the contact force between the pushing assembly and the thick end of the elastic wedge ring. This can increase the lateral force exerted by the elastic wedge ring on the inner cone ring of the flange in the direction of the central axis of the inner cone ring of the flange, thereby further improving the stability of the inner cone ring of the flange on the optical axis of the milling cutter shank. Moreover, as the rotation speed of the milling cutter shank gradually increases, the contact force between the pushing assembly and the thick end of the elastic wedge ring can be further increased, thereby further improving the stability of the inner cone ring of the flange on the optical axis of the milling cutter shank when the milling cutter shank rotates at high speed. Meanwhile, the vertical force exerted by the elastic wedge ring on the inner cone ring of the flange, parallel to the central axis of the inner cone ring, can further improve the stability of the connection between the inner cone ring and the rigid outer sleeve. Specifically, the flange of the inner cone ring is provided with a through hole. After the bolt passes through the through hole on the inner cone ring, it is directly screwed into the threaded blind hole machined on the end face of the rigid outer sleeve. The length direction of the threaded blind hole is in the same direction as the central axis of the rigid outer sleeve. In this way, based on the increase of its vertical force, the preload of the bolt can be increased, thereby improving the stability of the connection between the inner cone ring and the rigid outer sleeve. Furthermore, after the milling cutter holder stops rotating, the first movable plate is not subjected to centrifugal force. Compared to when the milling cutter holder is rotating, the lateral and vertical forces exerted by the elastic wedge ring on the inner cone ring of the flange are reduced, thus facilitating the removal of bolts. 3. Further, by setting a first abutment block and a second abutment block, the first abutment block is located in the second main slide groove and the second abutment block is located in the second auxiliary slide groove. The first inclined portion on the first abutment block abuts against the second inclined portion on the second abutment block. This allows the first abutment block to move along the length direction of the second main slide groove when the force of the first spring pulling the first abutment block increases. Under the guidance of the abutment action of the first and second inclined portions, the second abutment block moves along the length direction of the second auxiliary slide groove. This increases the contact force between the second abutment block and the thick end, thereby increasing the magnitude of the lateral force and the vertical force applied by the elastic wedge ring to the inner cone ring of the flange in the direction of the central axis of the inner cone ring of the flange. This facilitates the correlation between the centrifugal force on the first movable plate and the abutment force between the second abutment block and the thick end, so that additional force can be selectively applied to or removed from the inner cone ring of the flange depending on the stationary or rotating state of the milling cutter shank. In this application, the additional force refers to the force increased based on the centrifugal force applied to the first movable plate. 4. Furthermore, by setting a first air passage and a second air passage on the first movable plate, and connecting the third air passage to the first chamber and the first slide groove, when the milling cutter shank is not rotating, the first movable plate retracts into the first slide groove, and its first opening and second opening are also located in the first slide groove. At this time, the first opening and the second opening are blocked by the inner wall of the first slide groove, making it difficult for substances in the external environment to enter the first chamber through the first opening or the second opening. In this way, when the cutter ring device is assembled on the milling cutter shank and the milling cutter is in a stopped state, the probability of dust and other substances in the outside air contaminating the circuit board in the first chamber can be reduced, which helps to improve the service life of the circuit board. When the milling cutter is working, the cutter shank rotates. The centrifugal force generated by the rotation of the cutter shank causes the first movable plate to extend from the first slide groove, and the first and second openings to extend out of the first slide groove. Thus, during climb milling, with the first movable plate extended from the first slide groove and the first and second openings extending out of the first slide groove, gas from the external environment can sequentially enter the first chamber through the first opening, the first air passage, the first slide groove, and the third air passage. Furthermore, gas in the first chamber can be discharged to the external environment through the third air passage, the first slide groove, the second air passage, and the second opening. This facilitates gas exchange between the first chamber and the external environment, and further... The circuit board in the first chamber is cooled, which further improves the stability of the circuit board during operation. At the same time, when the milling cutter is working, the first movable plate can extend from the first slide groove. When the first movable plate is extended from the first slide groove, it rotates around the central axis of the milling cutter shank as the milling cutter shank rotates. The part of the first movable plate that extends out of the first slide groove is similar to a blade structure. The first movable plate has a certain thickness, which can accelerate the surrounding airflow when the first movable plate rotates. Since the cutter ring device is close to the milling cutter and the workpiece, it helps to remove heat from the cutter and the workpiece, which is beneficial for cooling the cutter. Furthermore, a limiting groove is provided on the first slide groove, and a limiting block is provided on the first movable plate. The limiting groove and the limiting block are adapted to each other. The length direction of the limiting groove is in the same direction as the length direction of the first slide groove. When the first movable plate moves along the length direction of the first slide groove, the limiting block moves along the length direction of the limiting groove. The limiting block and the limiting groove cooperate to prevent the first movable plate from separating from the first slide groove, thereby preventing the first movable plate from extending completely out of the first slide groove and improving the stability of the cooperation between the first limiting plate and the first slide groove.

[0024] Example 1: This example provides a tool ring device for monitoring milling vibration. See [link to example]. Figures 1-3As shown, it includes an inner conical ring 1, an elastic wedge ring 2, and a rigid outer sleeve 3. Both the inner conical ring 1 and the elastic wedge ring 2 are open-ring structures. The elastic wedge ring 2 is elastic and has a wedge-shaped cross-section. The inner conical ring 1 of the flange is used to be sleeved on the milling cutter holder. An elastic wedge ring 2 and a rigid outer sleeve 3 are sequentially sleeved on the outer side of the inner conical ring 1 of the flange. The inner conical ring 1 and the rigid outer sleeve 3 of the flange are connected by bolts 4. The rigid outer sleeve 3 and the inner cone ring 1 of the flange cooperate to apply pressure to the elastic wedge ring 2, so that the elastic wedge ring 2 applies a lateral force pointing towards the central axis of the inner cone ring 1 and a vertical force parallel to the central axis of the inner cone ring 1 to the inner cone ring 1. The rigid outer casing 3 is used to assemble circuit boards, which include a sensing and signal conditioning board, a main control and data processing board, a wireless communication board, a power management board, a battery board, and an interface and charging board.

[0025] In this application, during the installation of the cutter ring device on the milling cutter holder, the rigid outer sleeve 3 is first placed on the milling cutter holder, then the elastic wedge ring 2 is placed on the milling cutter holder, and then the flange inner cone ring 1 is placed on the milling cutter holder, so that the elastic wedge ring 2 is sandwiched between the flange inner cone ring 1 and the rigid outer sleeve 3. Bolts 4 are then used to connect the flange inner cone ring 1 and the rigid outer sleeve 3. Specifically, the inner wall of the rigid outer sleeve 3 is cylindrical, the outer wall of the elastic wedge ring 2 is cylindrical, and the inner wall has an inner cone surface structure. The cone angle α corresponding to the inner cone surface is typically between 5° and 15°, preferably 8°. The outer wall of ring 1, which contacts the inner wall of the elastic wedge ring 2, has an outer conical surface structure. The cone angle of the outer conical surface on the flange inner conical ring 1 matches the cone angle of the inner conical surface on the elastic conical ring, i.e., their cone angles are equal or close. This improves the fit between the flange inner conical ring 1 and the elastic wedge ring 2 during their engagement. Simultaneously, the inner wall of the flange inner conical ring 1 is cylindrical to fit against the outer wall of the milling cutter shank. Furthermore, the thinner end of the elastic wedge ring 2 is inserted into the area between the flange inner conical ring 1 and the rigid outer sleeve 3 before the thicker end. Thus, the rigid outer sleeve 3 and the flange inner conical ring 1... When pressure is applied to the elastic wedge ring 2, the elastic wedge ring 2 can apply a lateral force pointing towards the central axis of the flange inner cone ring 1 and a vertical force parallel to the central axis of the flange inner cone ring 1. Since both the flange inner cone ring 1 and the elastic wedge ring 2 are open-loop structures, the lateral force can deform the flange inner cone ring 1, making it more securely clamped onto the milling cutter shank, and the inner wall of the flange inner cone ring 1 more firmly attached to the outer wall of the optical axis section of the milling cutter shank. Simultaneously, in this application, based on the flange inner cone ring 1 with its open-loop structure... When the sidewall of the conical ring 1 is compressed, it can cause the inner conical ring 1 of the flange to bend and deform, that is, change the diameter of the cylindrical structure corresponding to the inner sidewall of the inner conical ring 1 of the flange. This allows the tool ring device of this application to be adapted to tool holders with various optical shaft sections of different diameters, further improving the compatibility between the tool ring device of this application and the milling cutter holder. There is no need to modify the existing tool holder and machine tool. The tool ring device of this application can be installed on the optical shaft of the existing milling cutter holder to monitor the vibration state of the milling process in real time. In this way, without changing the original structure of the machine tool and tool holder, the purpose of convenient installation, accurate signal and moderate cost can be achieved. For the inner conical ring 1 of the flange, its inner surface is a precision cylindrical hole that mates with the optical axis of the tool holder, and its outer surface is a conical surface. The function of the inner conical ring 1 of the flange is to directly hold the optical axis of the tool holder. In the free state, its inner hole diameter is slightly larger than the diameter of the target optical axis section of the tool holder. The opening design gives it the ability to undergo radial elastic deformation. For the sensing and signal conditioning board, it integrates a triaxial high-frequency response MEMS accelerometer, which is used to simultaneously measure vibrations in the X, Y, and Z directions. It also integrates an onboard precision operational amplifier and a passive network to form an anti-aliasing filter and a programmable gain amplifier, which are used to perform low-noise conditioning on weak raw sensor signals. For the main control and data processing board, its core is a high-performance, low-power ARM Cortex-M series microcontroller, which is responsible for system scheduling, high-speed analog-to-digital conversion of the conditioned analog signal, and running embedded algorithms to complete time-domain statistics (such as RMS value, peak value), fast Fourier transform and characteristic frequency band energy calculation in real time. For the wireless communication board, it integrates a low-power Bluetooth or Wi-Fi module and is equipped with a miniature ceramic antenna. The wireless communication board is responsible for transmitting the characteristic data stream processed by the main control board to the gateway or local receiving device in the workshop through the wireless protocol. The power management board has a built-in high-efficiency, multi-output switching power supply chip, a lithium battery charging management chip, and overvoltage, overcurrent, and short-circuit protection circuits. The power management board is responsible for drawing power from the battery and providing a clean and stable operating voltage for all other circuit boards. The solar panel uses two curved soft-pack lithium polymer batteries. As for the interface and charging pad, it integrates a wireless charging receiving coil that conforms to standards such as Qi and / or magnetic waterproof wired charging contacts to achieve contactless energy replenishment of the system. Meanwhile, all circuit boards are electrically interconnected through flexible flat cables or board-to-board connectors to form a compact three-dimensional circuit network. The specific sensing and signal conditioning boards, main control and data processing boards, wireless communication boards, power management boards, battery boards, and interface and charging boards, as well as the specific methods of assembling the circuit boards on the carrier, are all existing technologies. Furthermore, the core inventive point of this application is not the circuit board itself, so the detailed structure and specific assembly method of the circuit board will not be described in this application.

[0026] As a preferred embodiment, based on the above method, the cutter ring device for monitoring milling vibration further includes a cutter ring housing 5. The cutter ring housing 5 is cylindrical and is used to thread into the inner conical ring 1 of the flange. When the cutter ring housing 5 is threaded into the inner conical ring 1 of the flange, the top of the cutter ring housing 5 abuts against the rigid outer sleeve 3, and the cutter ring housing 5, the rigid outer sleeve 3, and the inner conical ring 1 of the flange cooperate to form a first chamber 6, in which the circuit board is located.

[0027] Furthermore, by setting a blade ring housing 5, which is threadedly engaged with the inner conical ring 1 of the flange, the top of the blade ring housing 5 abuts against the rigid outer sleeve 3 when the blade ring housing 5 and the inner conical ring 1 are threadedly engaged. This allows the blade ring housing 5, the rigid outer sleeve 3, and the inner conical ring 1 of the flange to cooperate to form a first chamber 6, which facilitates the placement of the circuit board in the first chamber 6. The blade ring housing 5 and the inner conical ring 1 of the flange adopt an interference fit thread design, so as to improve the stability of the thread engagement between the blade ring housing 5 and the inner conical ring 1 of the flange when the thread diameter on the inner conical ring 1 of the flange changes slightly.

[0028] Example 2: Based on the technical solution of Example 1, further details are provided below. Figures 1-9 As shown, a first sliding groove 7 and a second sliding groove 8 are formed on the rigid outer sleeve 3. A first movable plate 9 is slidably disposed in the first sliding groove 7, and a pushing component 10 is disposed in the second sliding groove 8. A first spring 11 is connected between the first movable plate 9 and the pushing component 10. The first spring 11 is elastic. The elastic wedge ring 2 includes a thick end 12 and a thin end 13, the thickness of the thick end 12 is greater than the thickness of the thin end 13, and the pushing component 10 is used to abut against the thick end 12 of the elastic wedge ring 2. When the rotational speed of the milling cutter shank increases, under the action of centrifugal force, the first movable plate 9 can move relative to the first slide groove 7 in a direction away from the central axis of the rigid outer sleeve 3, and the first spring 11 is stretched. The stretched first spring 11 can pull the pushing assembly 10 to increase the contact force between the pushing assembly 10 and the thick end 12 of the elastic wedge ring 2.

[0029] Furthermore, by setting the first movable plate 9, the first spring 11, and the pushing assembly 10, when the milling cutter changes from a stopped state to a working state, the milling cutter shank changes from a stationary state to a rotating state. Under the action of centrifugal force, the first movable plate 9 can move relative to the first slide groove 7 in a direction away from the central axis of the rigid outer sleeve 3, and stretch the first spring 11. After being pulled by the first movable plate 9, the first spring 11 can pull the pushing assembly 10, thereby increasing the contact force between the pushing assembly 10 and the thick end 12 of the elastic wedge ring 2. This can increase the lateral force exerted by the elastic wedge ring 2 on the inner cone ring 1 of the flange in the direction of the central axis of the inner cone ring 1 of the flange, thereby further improving the stability of the inner cone ring 1 of the flange surrounding the optical axis of the milling cutter shank. Moreover, as the rotation speed of the milling cutter shank gradually increases, the contact force between the pushing assembly 10 and the thick end 12 of the elastic wedge ring 2 can be further increased, thereby further improving the stability of the inner cone ring 1 of the flange surrounding the optical axis of the milling cutter shank when the milling cutter shank rotates at high speed. Meanwhile, the vertical force exerted by the elastic wedge ring 2 on the inner cone ring 1 of the flange, parallel to the central axis of the inner cone ring 1, can further improve the stability of the connection between the inner cone ring 1 and the rigid outer sleeve 3. Specifically, the flange of the inner cone ring 1 is provided with a through hole 14. After the bolt 4 passes through the through hole 14 on the inner cone ring 1, it is directly screwed into the threaded blind hole machined on the end face of the rigid outer sleeve 3. The length direction of the threaded blind hole is in the same direction as the central axis of the rigid outer sleeve 3. In this way, based on the increase of its vertical force, the preload of the bolt 4 can be increased, thereby improving the stability of the connection between the inner cone ring 1 and the rigid outer sleeve 3. Furthermore, after the milling cutter holder stops rotating, the first movable plate 9 is not subjected to centrifugal force. Compared to when the milling cutter holder is rotating, the lateral and vertical forces exerted by the elastic wedge ring 2 on the inner cone ring 1 of the flange are reduced, thus facilitating the removal of the bolt 4.

[0030] In a preferred embodiment, based on the above method, the pushing component 10 further includes a first abutment block 15 and a second abutment block 16, and the second slide groove 8 includes a second main slide groove 17 and a second auxiliary slide groove 18. The length direction of the second main slide groove 17 is perpendicular to the length direction of the second auxiliary slide groove 18, and the length direction of the second main slide groove 17 is in the same direction as the length direction of the first slide groove 7. The first abutment block 15 is located in the second main slide groove 17, and the second abutment block 16 is located in the second auxiliary slide groove 18. The first abutment block 15 is used to connect with the first spring 11, and the second abutment block 16 is used to abut against the thick end 12. The first abutment 15 has a first inclined portion 19, and the second abutment 16 has a second inclined portion 20. The first inclined portion 19 is used to abut against the second inclined portion 20. When the force of the first spring 11 pulling the first abutment 15 increases, the first abutment 15 can move along the length direction of the second main slide groove 17. Under the guidance of the action of the first inclined portion 19 and the second inclined portion 20 abutting against each other, the second abutment 16 can move along the length direction of the second auxiliary slide groove 18 to increase the contact force between the second abutment 16 and the thick end 12.

[0031] Furthermore, by setting a first abutment block 15 and a second abutment block 16, with the first abutment block 15 located in the second main slide groove 17 and the second abutment block 16 located in the second auxiliary slide groove 18, the first inclined portion 19 on the first abutment block 15 abuts against the second inclined portion 20 on the second abutment block 16. This allows the first abutment block 15 to move along the length direction of the second main slide groove 17 when the force of the first spring 11 pulling the first abutment block 15 increases. Guided by the abutting action of the first inclined portion 19 and the second inclined portion 20, the second abutment block 16 moves along the length direction of the second auxiliary slide groove 18, thereby increasing the distance between the second abutment block 16 and the thick end 12. The contact force between them increases the magnitude of the lateral force exerted by the elastic wedge ring 2 on the inner cone ring 1 of the flange in the direction of the central axis of the inner cone ring 1 of the flange, and the vertical force in the direction parallel to the central axis of the inner cone ring 1 of the flange. In this way, it is convenient to associate the centrifugal force on the first movable plate 9 and the contact force between the second abutment 16 and the thick end 12, so that additional force can be selectively applied to or removed from the inner cone ring 1 of the flange depending on the stationary or rotating state of the milling cutter shank. The additional force in this application refers to the force increased based on the first movable plate 9 under the condition of being subjected to centrifugal force.

[0032] As a preferred embodiment, based on the above method, the length direction of the first groove 7 is perpendicular to the central axis of the rigid jacket 3.

[0033] Furthermore, the length direction of the first slide groove 7 is perpendicular to the central axis of the rigid outer sleeve 3, so that when the milling cutter holder rotates, it is more conducive to the first movable plate 9 moving along the length direction of the first slide groove 7 under the action of centrifugal force.

[0034] Example 3: Based on the technical solution of Example 2, further details are provided below. Figure 1 , Figures 4-11 As shown, the first movable plate 9 is provided with a first air passage 21 and a second air passage 22. The first air passage 21 and the second air passage 22 are symmetrically arranged about the central axis of the first movable plate 9. One end of the first air passage 21 extends to the side wall of the first movable plate 9, and the other end is connected to the first slide groove 7. One end of the second air passage 22 extends to the other side wall of the first movable plate 9, and the other end is connected to the first slide groove 7. The opening on the first air passage 21 extending to the side wall of the first movable plate 9 is the first opening 23, and the opening on the second air passage 22 extending to the side wall of the first movable plate 9 is the second opening 24. When the milling cutter performs climb milling, the opening direction of the first opening 23 is in the same direction as the rotation direction of the rigid sleeve 3, and the opening direction of the second opening 24 is opposite to the rotation direction of the rigid sleeve 3. The rigid outer sleeve 3 is provided with a third air passage 25, which is used to connect the first chamber 6 and the first slide groove 7. When the milling cutter holder is not rotating, the first movable plate 9 retracts into the first slide groove 7; When the milling cutter holder rotates, under the action of centrifugal force, the first movable plate 9 can extend out of the first slide groove 7, and the first opening 23 and the second opening 24 can extend out of the first slide groove 7.

[0035] Furthermore, by setting a first air passage 21 and a second air passage 22 on the first movable plate 9, and connecting the third air passage 25 to the first chamber 6 and the first slide groove 7, when the milling cutter shank is not rotating, the first movable plate 9 retracts into the first slide groove 7, and its first opening 23 and second opening 24 are also located in the first slide groove 7. At this time, the first opening 23 and the second opening 24 are blocked by the inner wall of the first slide groove 7, and substances in the external environment are difficult to enter the first chamber 6 through the first opening 23 or the second opening 24. In this way, when the cutter ring device is assembled on the milling cutter shank and the milling cutter is in a stopped state, the probability of dust and other substances in the outside air contaminating the circuit board in the first chamber 6 can be reduced, which is conducive to improving the service life of the circuit board. When the milling cutter is working, the cutter shank rotates. The centrifugal force generated by the rotation of the cutter shank causes the first movable plate 9 to extend from the first slide groove 7, and the first opening 23 and the second opening 24 to extend out of the first slide groove 7. Thus, during climb milling, with the first movable plate 9 extended from the first slide groove 7 and the first opening 23 and the second opening 24 extending out of the first slide groove 7, gas from the external environment can sequentially enter the first chamber 6 through the first opening 23, the first air passage 21, the first slide groove 7, and the third air passage 25. Furthermore, the gas in the first chamber 6 can be discharged to the external environment through the third air passage 25, the first slide groove 7, the second air passage 22, and the second opening 24. This facilitates the exchange of gas within the first chamber 6 with the external environment. The gas exchange in the environment is more conducive to heat dissipation of the circuit board in the first chamber 6, further improving the stability of the circuit board in the working state; at the same time, since the first movable plate 9 can extend from the first slide groove 7 when the milling cutter is working, when the first movable plate 9 is in the extended state from the first slide groove 7, as the milling cutter shank rotates, the first movable plate 9 rotates around the central axis of the milling cutter shank. The part of the first movable plate 9 that extends out of the first slide groove 7 is similar to a blade structure. The first movable plate 9 has a certain thickness, which can accelerate the surrounding air flow when the first movable plate 9 rotates. Since the cutter ring device is close to the milling cutter and the workpiece, it helps to remove the heat from the cutter and the workpiece, which is conducive to heat dissipation of the cutter. Furthermore, a limiting groove 26 is provided on the first sliding groove 7, and a limiting block 27 is provided on the first movable plate 9. The limiting groove 26 and the limiting block 27 are adapted to each other. The length direction of the limiting groove 26 is in the same direction as the length direction of the first sliding groove 7. When the first movable plate 9 moves along the length direction of the first sliding groove 7, the limiting block 27 moves along the length direction of the limiting groove 26. The limiting block 27 and the limiting groove 26 cooperate to prevent the first movable plate 9 from separating from the first sliding groove 7, thereby preventing the first movable plate 9 from completely extending out of the first sliding groove 7, thereby improving the stability of the first limiting plate and the first sliding groove 7.

[0036] In a preferred embodiment, based on the above method, the first movable plate 9 further includes a movable plate body 28 and an adjustment knob 29. The first air passage 21 and the second air passage 22 are disposed on the movable plate body 28. The adjustment knob 29 is threadedly connected to the movable plate body 28. The adjustment knob 29 is connected to the first spring 11. The length direction of the adjustment knob 29, the length direction of the first movable plate 9, and the length direction of the first slide groove 7 are in the same direction.

[0037] Furthermore, by setting an adjustment knob 29, one end of the first spring 11 is connected to the adjustment knob 29, and the other end is connected to the first abutment 15. By rotating the adjustment knob 29 relative to the movable plate body 28, the position of the adjustment knob 29 along the length direction of the first movable plate 9 can be adjusted. Specifically, when the cutter ring device and the milling cutter holder are not rotated, by adjusting the position of the adjustment knob 29, the end of the first movable plate 9 facing the central axis of the rigid outer sleeve 3 can abut against the end of the first slide groove 7, and the first spring 11 is in a stretched state. At this time, the stretch of the first spring 11 is determined by the position of the adjustment knob 29 along the length direction of the first movable plate 9; or, in When the cutter ring device and the milling cutter holder are not rotated, the position of the adjusting knob 29 can be adjusted so that the end of the first movable plate 9 facing the central axis of the rigid outer sleeve 3 is not in contact with the end of the first slide groove 7. At this time, the first spring 11 can be in its natural state. Based on this, the position of the first movable plate 9 along the length direction of the first slide groove 7 is determined by the position of the adjusting knob 29 along the length direction of the first movable plate 9. In this way, it is convenient to adjust the magnitude of the centrifugal force required to drive the first movable plate 9 to extend out of the first slide groove 7, or to make the first opening 23 and the second opening 24 extend out of the first slide groove 7, thereby further improving the flexibility of the cutter ring device of this application in actual use.

[0038] As a preferred embodiment, based on the above method, the rigid outer sleeve 3 is further provided with a plurality of first sliding grooves 7, and the number of the first movable plate 9, the first spring 11 and the pushing assembly 10 are adapted to the number of the first sliding grooves 7.

[0039] Specifically, six first sliding grooves 7 can be provided on the rigid outer sleeve 3. The six sliding grooves are evenly distributed around the central axis of the rigid outer sleeve 3. The number of its first movable plate 9, first spring 11 and pushing component 10 is also six.

[0040] As a preferred embodiment, based on the above method, six planes 30 are further formed on the outer side wall of the rigid jacket 3, the six planes 30 are distributed around the central axis of the rigid jacket 3, and the circuit board is mounted on the planes 30.

[0041] Furthermore, by setting up six planes 30, the circuit board is mounted on the planes 30. Specifically, one plane 30 is equipped with a sensing and signal conditioning board, another plane 30 is equipped with a main control and data processing board, another plane 30 is equipped with a wireless communication board, another plane 30 is equipped with a power management board, another plane 30 is equipped with a battery board, and another plane 30 is equipped with an interface and charging board, so as to facilitate the mounting of the circuit board on the rigid jacket 3.

[0042] Example 4: This example also provides a milling cutter assembly, see below. Figure 12 As shown, the device includes a tool ring device for monitoring milling vibration as described above, and also includes a milling cutter holder body 31, wherein the tool ring device is used to be mounted on the side wall of the milling cutter holder body 31.

[0043] In this application, the cutter ring device is installed on the side wall of the milling cutter holder body 31. Specifically, the cutter ring device is installed on the side wall of the optical axis section on the milling cutter holder body 31. In this way, without changing the original structure of the machine tool and the cutter holder, it can achieve the purpose of convenient installation, accurate signal and moderate cost.
