Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic cutting tool technology, specifically relating to ultrasonic variable direction cutting tools and their adjustment devices. Background Technology

[0002] Traditional cutting tools typically consist of a handle, a blade, and a drive motor. The blade is mounted on the handle, and the motor drives the handle to rotate or reciprocate, thus cutting the material. However, this cutting method is prone to problems such as high cutting resistance and material adhesion when cutting sticky materials (such as self-adhesive labels). To reduce cutting resistance, ultrasonic technology has been applied to create ultrasonic cutting tools. The principle is to generate high-frequency vibrations through an ultrasonic generator, converting electrical energy into mechanical energy. This causes the tool to generate minute mechanical vibrations during the cutting process. These minute vibrations break up the surface of the material being cut, reducing cutting resistance and achieving efficient, precise, and low-heat-damage cutting results.

[0003] However, existing technologies still have some limitations: existing ultrasonic cutters are prone to breakage when changing the cutting direction, especially when turning at high speed; and the tip extension distance adjustment method is mostly top adjustment, which is complex and inconvenient for wire arrangement. Utility Model Content

[0018] The coil circuit board is positioned above the bearing, and the internal coil is fixedly mounted on the coil circuit board. The internal coil is slidably mounted coaxially with the tool module.

[0019] In one embodiment of this utility model, at least two sliding grooves are provided on the outer side of the movable sleeve, and a plurality of rolling elements are provided in the sliding grooves. The rolling elements abut against the inner wall surface of the tool holder housing, so that the movable sleeve slides parallel up and down relative to the tool holder housing.

When maintenance or replacement is required, the entire ultrasonic vibration component can be easily removed by simply unscrewing the fixing nut cover from the tool holder housing. This avoids the cumbersome process of disassembling multiple parts in the traditional structure, greatly simplifies the maintenance and replacement steps, and saves time and labor costs.

[0032] 4. This utility model integrates multiple functional components together, such as the integrated fixed structure of the internal coil, coil circuit board, bearing, bottom support plate, and movable sleeve, reducing the overall space occupation and making the entire tool device lighter. Furthermore, the coaxial design of the internal coil and coil circuit board, combined with the movable arrangement of the bottom support plate and bearing, ensures smooth and stable up-and-down sliding of the tool module and good rotational stability. Simultaneously, the sliding groove and rolling element design on the outer side of the movable sleeve allows it to slide parallel up and down relative to the tool holder housing, reducing frictional wear between mechanical components. Therefore, the rotary drive assembly of this utility model has a simple structure and is lightweight, requiring only a small movable cavity inside the tool, while also reducing the burden on the ultrasonic vibration assembly, thus achieving a highly efficient cutting effect with very low ultrasonic crystal power.

[0033] 5.

Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please refer to Figures 1-4 One embodiment of this utility model provides an ultrasonic variable direction cutting tool, including: a tool holder housing 10, a cutting tool module 20, an ultrasonic vibration component 30, and a rotary drive component 40;

[0043] The cutting tool module 20 is movably disposed inside the tool holder housing 10, and the bottom of the cutting tool module 20 extends out of the bottom of the tool holder housing 10;

[0044] The ultrasonic vibration component 30 is disposed on the top of the tool holder housing 10. The ultrasonic vibration component 30 is connected to the tool module 20 in a driving connection so that the ultrasonic vibration component 30 drives the tool module 20 to vibrate up and down when it is running.

[0045] The rotary drive assembly 40 is disposed inside the tool holder housing 10, and the rotary drive assembly 40 is connected to the tool module 20 for transmission, so as to drive the tool module 20 to adjust the cutting direction when the rotary drive assembly 40 is running.

[0046] An elastic cavity 50 is formed below the rotary drive assembly 40 and at the bottom of the tool holder housing 10.

[0047] Understandably, in this embodiment, the rotary drive assembly 40 generates a rotating magnetic field after the drive current is applied. Under the action of the rotating magnetic field, the tool module 20 rotates rapidly, allowing the cutting direction of the tool module 20 to be quickly adjusted. Also, a movable cavity with a certain gap is formed between the rotary drive assembly 40 and the tool holder housing 10. When the ultrasonic crystal drive voltage is applied to the ultrasonic vibration assembly 30, the ultrasonic crystal 32 in the ultrasonic vibration assembly 30 starts to vibrate and transmits the vibration to the tool module 20 through the ejector pin cover 33. The tool module 20 then pushes against the rotary drive assembly 40 and begins to vibrate up and down at high speed.

[0048] Therefore, the ultrasonic variable-direction tool of this embodiment can be used to achieve the following technical effects:

[0049] 1. The introduction of ultrasonic vibration significantly improves cutting efficiency and reliability. Ultrasonic vibration can significantly reduce the friction between the blade and the material, reduce cutting resistance, and make the cutting process smoother. At the same time, the high-frequency vibration generated by ultrasonic vibration can prevent materials (such as adhesive) from adhering to the blade, keeping the blade clean and sharp, and further improving the cutting quality.

[0050] 2. A tool direction adjustment structure is introduced. When the cutting direction needs to be changed, the internal coil 42 is energized to actively adjust the tool direction, ensuring that the blade always faces the cutting direction. This active adjustment mechanism not only avoids the risk of tool breakage that may occur when traditional tools turn at high speeds, but also ensures the continuity and stability of the cutting process, thereby improving the reliability and safety of cutting.

[0051] Please refer to Figure 1 and Figure 3 and Figure 4 In one embodiment of the present invention, the ultrasonic vibration assembly 30 includes a fixing nut cover 31, an ultrasonic crystal 32, and a pin cover 33.

[0052] The fixing nut cover 31 is fixedly disposed on the top of the ultrasonic crystal 32, and the fixing nut cover 31 is threadedly connected to the top of the knife holder housing 10 to close the top opening of the knife holder housing 10.

[0053] The ejector pin cover 33 is fixedly disposed at the bottom of the ultrasonic crystal 32, and the ejector pin cover 33 abuts against the tool module 20.

[0054] Understandably, in this embodiment, the ultrasonic variable-direction tool can be used to achieve the following technical effects:

[0055] 1. The integrated fixing structure of the fixing nut cover 31, ultrasonic crystal 32 and ejector pin cover 33 makes the ultrasonic vibration assembly an independent and compact module. When maintenance or replacement is required, the entire ultrasonic vibration assembly 30 can be easily removed by simply unscrewing the fixing nut cover 31 from the tool holder housing 10. This avoids the cumbersome process of disassembling multiple parts in the traditional structure, greatly simplifies the maintenance and replacement steps, and saves time and labor costs.

[0056] In one embodiment of this utility model, the fixing nut cover 31 is provided with a connection port (not shown) for leading out a power supply wire (not shown);

[0057] The power supply wire includes at least the power supply harness for the ultrasonic crystal 32 and the rotary drive assembly 40; and / or, the connection port is also used to lead out the control line of the connection port.

[0058] Understandably, in this embodiment, the power supply harness is used to provide the ultrasonic crystal driving voltage to the ultrasonic crystal 32 and to supply the driving current to the rotary drive assembly 40; the control line is used to input action commands to the rotary drive assembly 40 or to collect action data.

[0059] The ultrasonic variable-direction cutter of this embodiment can be used to lead the wire out from the upper end of the ultrasonic vibration component 30 through the connection port provided by the fixed nut cover 31, avoiding the interference between the wire and the adjustment mechanism in the traditional upper adjustment method.

[0060] In one embodiment of the present invention, the rotary drive assembly 40 includes a movable sleeve 41 and an internal coil 42 and a coil circuit board 43 disposed within the movable sleeve 41.

[0061] The bottom of the movable sleeve 41 is fixedly connected to a bottom support plate 44, and the upper surface of the bottom support plate 44 is fixedly connected to a bearing 45. The bottom support plate 44 is coaxially and movably arranged with the tool module 20 through the bearing 45; the lower surface of the bottom support plate 44 abuts against the elastic element.

[0062] The coil circuit board 43 is disposed above the bearing 45, and the internal coil 42 is fixedly disposed on the coil circuit board 43. The internal coil 42 is slidably disposed coaxially with the tool module 20.

[0063] Understandably, the ultrasonic variable cutter of this embodiment reduces the overall space occupied by the integrated fixed structure of the internal coil 42, coil circuit board 43, bearing 45, bottom support plate 44 and movable sleeve 41, making the entire cutter device lighter. In addition, the coaxial design of the internal coil 42 and coil circuit board 43, combined with the movable setting of the bottom support plate 44 and bearing 45, ensures that the up and down sliding process of the cutter module 20 is smooth and has good rotational stability.

[0064] In one embodiment of this utility model, at least two sliding grooves (not shown, the sliding grooves can be set as vertical grooves) are also provided on the outer side of the movable sleeve 41. A plurality of rolling elements 46 are provided in the sliding grooves. The rolling elements 46 abut against the inner wall surface of the tool holder housing 10 so that the movable sleeve 41 slides parallel up and down relative to the tool holder housing 10.

[0065] Understandably, in this embodiment, the sliding groove and rolling element 46 on the outer side of the movable sleeve 41 enable the movable sleeve 41 to slide parallel up and down relative to the tool holder housing 10, reducing frictional wear between mechanical parts. Therefore, the rotary drive assembly 40 of this utility model has a simple structure and light weight, requiring only a small movable cavity inside the tool, while also reducing the burden on the ultrasonic vibration assembly 30, thereby achieving a high-efficiency cutting effect with very low ultrasonic crystal 32 power.

[0066] In one embodiment of this utility model, the cutting tool module 20 is provided with a magnetic element 47 corresponding to the internal coil 42, and the cutting tool module 20 is elastically and tightly fitted with the magnetic element 47 through a rubber element;

[0067] The magnetic element 47 is located above the internal coil 42 and is coaxial with the internal coil 42. The internal coil 42 is used to drive the tool module 20 to rotate through the magnetic element 47 after being energized, so that the tool module 20 is oriented in the cutting direction.

[0068] Understandably, the coaxial design ensures that the magnetic field generated when the internal coil 42 is energized is precisely aligned with the magnetic component 47, enabling the tool module 20 to respond efficiently to changes in the magnetic field and achieve precise rotational drive; while the elastic tight fit ensures a stable connection between the tool module 20 and the magnetic component 47, maintaining a reliable connection even under high-frequency vibration.

[0069] In this embodiment, by controlling the current direction and intensity of the internal coil 42, the rotation direction of the tool module 20 can be actively adjusted to ensure that the blade always faces the cutting direction, thereby avoiding the risk of the traditional tool breaking when turning at high speed.

[0070] In one embodiment of the present invention, the magnetic element 47 includes rubidium magnets arranged in a dispersed manner.

[0071] In one scenario of this embodiment, the internal coil 42 is a three-phase coil. The structure of the three-phase coil makes the magnetic field distribution more uniform, reducing vibration and noise caused by uneven magnetic field. The three-phase coil acts as a stator, generating a magnetic field after being energized. The magnetic component 47 acts as a mover, rotating under the action of the magnetic field, which in turn drives the tool module 20 to rotate, thereby adjusting the cutting direction of the tool module 20. The rubidium magnet has a high magnetic energy density, and its dispersed arrangement ensures a uniform magnetic field distribution, further optimizing the coupling effect between the magnetic field and the tool module 20, and achieving fast and stable rotation.

[0072] Therefore, in this embodiment, when the cutting direction changes, the internal coil 42 is energized to actively change the direction of the tool, so that the blade always faces the cutting direction, avoiding the risk of the tool breaking when turning at high speed and improving the cutting effect.

[0073] In one embodiment of the present invention, the cutting tool module 20 is configured to be detachably connected to the cutting tool holder housing 10, for replacing the cutting blade in the cutting tool module 20 after disconnecting the ultrasonic vibration component 30, the rotary drive component 40 and the cutting tool module 20.

[0074] Understandably, in this embodiment, the detachable connection design allows users to quickly replace the blades in the tool module 20 after disconnecting the ultrasonic vibration assembly 30 and the rotary drive assembly 40 from the tool module 20. This significantly reduces the time required to replace the blades and improves replacement efficiency. Furthermore, the replacement process is more convenient, eliminating the need to disassemble the entire tool system.

[0075] In one embodiment of this utility model, a Hall sensor is also provided on the coil circuit board 43, the Hall sensor facing the tool module 20, for detecting the rotation angle of the tool module 20.

[0076] Understandably, in this embodiment, the Hall sensor determines the rotation angle of the cutter module 20 by detecting changes in the magnetic field. When the cutter module 20 rotates, the magnetic field generated by its magnetic component 47 (such as a neodymium magnet) passes through the Hall sensor, causing a change in the electrical signal output by the sensor. By reading and measuring the output signal of the Hall sensor in real time, precise control of the rotation direction of the cutter module 20 can be achieved. This real-time feedback mechanism enables the cutter module 20 to actively adjust the direction of the cutting edge according to changes in the cutting direction, ensuring that the cutting edge always faces the cutting direction and avoiding the risk of the blade breaking during high-speed turning.

[0077] In one embodiment of the present invention, a flange ring 60 is further provided on the outer side of the tool holder housing 10, the flange ring 60 being used to quickly connect the tool holder housing 10 to the tool holder.

[0078] Understandably, in this embodiment, the flange ring 60 is part of the tool holder housing 10, making the entire tool assembly structure more compact. The tool holder housing 10 can be connected to the tool support by bolts or nuts. When the tool needs to be replaced, the user only needs to loosen the bolts or nuts on the flange ring 60 to quickly separate the tool holder housing 10 from the tool support, replace the tool module 20, and then reconnect it.

[0079] In one embodiment of this utility model, an elastic element is provided in the elastic cavity 50, and the elastic element is configured to adjust the vertical vibration amplitude of the cutting tool module 20.

[0080] Please refer to Figures 1-3 In one embodiment of this utility model, an adjustment device is provided, which can be used in any of the ultrasonic variable direction cutters described in the above embodiments. It includes a cutter depth adjustment component 70, which is provided with a thread on its outer side. The cutter depth adjustment component 70 is threaded to the bottom of the cutter holder housing 10. The cutter depth adjustment component 70 is provided with a through hole, and the cutter module 20 passes through the cutter depth adjustment component 70 through the through hole.

[0081] Understandably, in this embodiment, the depth adjustment component 70 is provided with a through hole, through which the tool module 20 passes through the depth adjustment component 70, ensuring the stability of the tool module 20, while allowing the extension distance of the blade tip relative to the depth adjustment component 70 to be changed by moving the adjustment component up and down, thereby achieving different cutting depth effects.

[0082] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
