Description

Technical Field

[0001] This application relates to the field of ultrasonic equipment technology, and in particular to ultrasonic cutting tools. Background Technology

[0002] In the field of ultrasonic equipment technology, ultrasonic cutting blades exhibit highly efficient cutting capabilities due to their unique working principle. Their working principle involves generating high-frequency vibrations through an ultrasonic generator and transmitting these vibrations to the cutting head, enabling the cutting head to rapidly cut the workpiece under high-frequency vibration. Compared to traditional cutting tools, ultrasonic cutting blades offer advantages such as high cutting precision and smooth cuts, and have been widely used in numerous fields.

[0003] In related technologies, the cutter head and ultrasonic generator of an ultrasonic cutter are usually tightly connected to ensure the stability of vibration transmission. However, this tightly connected cutter head is generally not detachable, making the ultrasonic cutter's function relatively limited. In particular, when the cutter head is worn, damaged, or needs to be switched to different tasks, the cutter head cannot be replaced, making it difficult to meet diverse usage needs. Utility Model Content

[0004] Therefore, it is necessary to provide an ultrasonic cutting tool to address the problems of existing ultrasonic cutting tools, such as the inability to flexibly replace the cutting head and the relatively limited functionality.

[0040] See Figures 1 to 2The diagram shows a schematic representation of an ultrasonic cutter 10 according to an embodiment of this application. The ultrasonic cutter 10 provided in this embodiment includes a housing 100, an ultrasonic generating mechanism 200, and a cutter head 300. The ultrasonic generating mechanism 200 is connected to the housing 100; for example, the ultrasonic generating mechanism 200 can be tightly fixed to the inner wall of the housing 100 by screws. Optionally, the ultrasonic generating mechanism 200 may include an ultrasonic transducer and an amplitude transformer. The ultrasonic transducer is sequentially connected to the amplitude transformer and the cutter head 300. The ultrasonic transducer outputs a certain frequency, for example, a high frequency of about 40kHz, and radiates ultrasonic waves outward through vibration. The cutter head 300 includes a connecting component 310 and a cutter body 320. The connecting component 310 and the cutter body 320 can be made of high-strength metal. The connecting component 310 is detachably connected to the ultrasonic generating mechanism 200. The blade body 320 is connected to the connecting component 310, and a cutting edge 321 is provided on the side of the blade body 320 away from the connecting component 310. The blade body 320 is configured to vibrate under the action of ultrasonic waves emitted by the ultrasonic generating mechanism 200 to cut or grind the target object through the cutting edge 321. For example, the target object can be a 3D printed part, a plastic model holder, PVC (polyvinyl chloride) material, paper, acrylic, rubber, plaster, PCB (printed circuit board) board, wood, EVA (ethylene-vinyl acetate copolymer) material, foam, etc.

[0041] Through the above structural design, the ultrasonic cutter 10 of this embodiment utilizes the ultrasonic waves emitted by the ultrasonic generator 200 to cause the cutter head 300 to vibrate at high speed, resulting in advantages such as high efficiency, high precision, and smooth cuts when cutting or grinding target objects. Furthermore, the cutter head 300 of the ultrasonic cutter 10 is detachable. When replaced with a cutter head 300 for cutting harder materials, the ultrasonic generator 200 can drive the cutter head 300 to vibrate back and forth at high frequency for rapid cutting of the target object. When replaced with a cutter head 300 for fine grinding, the ultrasonic generator 200 can drive the cutter head 300 to vibrate back and forth at high frequency for grinding the surface of the target object. Therefore, the ultrasonic cutter 10 of this embodiment can replace different types of cutter heads 300 according to actual needs; that is, the ultrasonic cutter 10 can freely switch cutter heads 300 to selectively perform cutting or grinding operations, improving the flexibility of the ultrasonic cutter 10 and helping to meet diverse usage needs.

[0042] Optionally, see Figure 3As shown, in some embodiments, the thickness of the blade 321 gradually decreases towards the direction away from the connecting member 310, that is, the thickness of the blade 321 gradually thins from near the connecting member 310 towards the direction away from the connecting member 310. The side of the blade 321 away from the connecting member 310 is inclined along the length direction of the blade body 320, which is the overall length direction of the ultrasonic cutter 10. This embodiment adopts a design with a gradually changing and inclined blade 321 thickness. When cutting the target object, the thinner tip of the blade 321 can more easily cut into the target object, while the inclined angle can increase the lateral force during cutting, making the cutting process smoother and improving cutting efficiency.

[0043] Optionally, see Figure 4 As shown, in some embodiments, the thickness of the blade 321 is the same at all points, that is, the thickness of the blade body 320 is consistent at all points, in which case the blade body 320 has a roughly cuboid structure. The side of the blade 321 away from the connecting component 310 is perpendicular to the length direction of the blade body 320, wherein the length direction of the blade body 320 is the overall length direction of the ultrasonic cutter 10. This embodiment adopts a design where the blade 321 has the same thickness and is perpendicular, which ensures that the blade body 320 makes uniform contact with the surface of the target object when grinding, resulting in a smoother grinding effect and improving grinding accuracy.

[0044] In some embodiments, the connecting component 310 is threadedly connected to the ultrasonic generator 200, making the connection between the connecting component 310 and the ultrasonic generator 200 detachable. For example, an external thread is machined on the connecting component 310, and a matching internal thread is provided at the connecting end of the ultrasonic generator 200, thereby achieving a threaded connection between the two. The threaded connection method makes the installation and removal of the cutter head 300 more convenient and quick, without the need for complex tools. Of course, it should be understood that in other optional embodiments, the connecting component 310 and the ultrasonic generator 200 may also adopt other detachable connection methods such as snap-fit ​​connection.

[0045] See Figure 3 and Figure 4 As shown, the connecting component 310 is provided with a connecting groove 311, the shape of which is adapted to the blade body 320 so that the blade body 320 can be inserted into the connecting groove 311. To ensure a stable connection, the blade body 320 can be welded to the connecting component 310, and a sharp cutting edge 321 is machined on the side of the blade body 320 away from the connecting component 310. By enhancing the connection stability between the blade body 320 and the connecting component 310, the blade body 320 is less likely to loosen or fall off during ultrasonic vibration operation, which helps to ensure the safety and efficiency of cutting and grinding operations.

[0046] See Figure 1 , Figure 5 and Figure 6As shown, in some embodiments, the housing 100 adopts a split design, specifically including a handle housing 110 and a protective cover 120. The handle housing 110 is generally hollow and elongated. The ultrasonic generator 200 is connected to the handle housing 110 to securely mount the ultrasonic generator 200 inside the handle housing 110. The protective cover 120 is detachably connected to the handle housing 110, allowing the protective cover 120 to be removed when the ultrasonic cutter 10 is needed without affecting operation. The protective cover 120 has a protective cavity 121, the shape of which matches the cutter head 300. The protective cavity 121 is configured to accommodate the cutter head 300 when the protective cover 120 is connected to the handle housing 110. When the ultrasonic cutter 10 is not in use, the protective cover 120 is installed on the handle housing 110. At this time, the cutter head 300 is accommodated in the protective cavity 121, which can prevent the cutter head 300 from being impacted or damaged, extend the service life of the cutter head 300, and also prevent the cutter head 300 from being exposed and causing accidental injury.

[0047] See Figure 5 and Figure 6 As shown, in some embodiments, the handle housing 110 is provided with a locking groove 111. The locking groove 111 may be formed at the edge of the handle housing 110. The locking groove 111 is a rectangular groove and extends along the length of the ultrasonic cutter 10. The protective cover 120 includes a cover body 122 and a locking member 123. A protective cavity 121 is formed inside the cover body 122. The locking member 123 is movably connected to the cover body 122 and is configured to be inserted into the locking groove 111 to lock the cover body 122 and the handle housing 110. For example, the locking member 123 can be slidably connected to the cover body 122 through a slot, and the shape of the locking member 123 matches the locking groove 111.

[0048] In this embodiment, when the protective cover 120 is installed on the handle housing 110, the locking member 123 is pushed to insert into the locking groove 111 to engage with the handle housing 110, thus firmly locking the cover 122 and the handle housing 110, preventing the protective cover 120 from falling off in case of accident, further improving the protection of the blade 300, and ensuring the safety of the ultrasonic blade 10 during carrying and storage. When it is necessary to remove the protective cover 120, the locking member 123 can be pulled out from the locking groove 111 to release the restriction on the cover 122 and the handle housing 110, thereby allowing the protective cover 120 to be removed from the handle housing 110. Thus, by pushing and pulling the locking member 123 back and forth, the cover 122 and the handle housing 110 can be self-locked, preventing the protective cover 120 from accidentally falling off and causing injury to the blade 300, and also effectively preventing children or users from accidentally touching the blade 300 and getting injured.

[0049] See Figure 1 , Figure 2 and Figure 5As shown, in some embodiments, the outer surface of the handle housing 110 is provided with anti-slip protrusions 112. For example, the anti-slip protrusions 112 are hemispherical or strip-shaped structures, and there can be multiple anti-slip protrusions 112, which are evenly distributed in a certain area on the outer surface of the handle housing 110. The anti-slip protrusions 112 can increase the friction between the user's hand and the handle housing 110, and can effectively prevent the ultrasonic cutter 10 from slipping from the hand even when the hands are sweaty or the operating environment is harsh, thereby improving the safety of operation.

[0050] Furthermore, the handle housing 110 is provided with heat dissipation holes 113, which are distributed around the ultrasonic generator 200. The heat dissipation holes 113 can dissipate the heat generated by the ultrasonic generator 200 during operation in a timely manner, preventing the ultrasonic generator 200 from degrading or being damaged due to overheating, and thus helping to extend the service life of the ultrasonic cutter 10.

[0051] Furthermore, the handle shell 110 is made of a single piece of aluminum alloy and undergoes anodized surface coating treatment, thereby enhancing the tactile feel of the hand and improving heat dissipation, reducing the waiting time required for standby cooling due to overheating.

[0052] See Figure 2 and Figure 7 As shown, in some embodiments, the ultrasonic cutter 10 further includes a toggle switch 400, which is movably connected to the handle housing 110. The toggle switch 400 is mounted on the side of the handle housing 110 and is electrically connected to the ultrasonic generator 200 via a wire. The toggle switch 400 has an on-state and an off-state, and the toggle switch 400 has clear markings to distinguish between the on-state and off-state, for example, "ON" for on-state and "OFF" for off-state. The toggle switch 400 is configured to be toggled to the on-state by external force to power on the ultrasonic generator 200, or to the off-state by external force to power off the ultrasonic generator 200. Thus, the user can conveniently control the power on and off of the ultrasonic generator 200 through the toggle switch 400, making operation simple. When continuous operation is required, the toggle switch 400 can keep the ultrasonic generator 200 continuously powered to meet the needs of long-term cutting or grinding.

[0053] Further, see Figure 2 and Figure 7As shown, in some embodiments, the ultrasonic cutter 10 further includes a jog switch 500, which is movably connected to the handle housing 110. The jog switch 500 is configured to contact the ultrasonic generator 200 to turn it on when pressed by an external force, and to disconnect from the ultrasonic generator 200 to turn it off when the external force is removed. For example, the jog switch 500 is installed on the handle housing 110 near the thumb grip position. The jog switch 500 is electrically connected to the ultrasonic generator 200 via a wire. The jog switch 500 adopts a push-button design and has an internal elastic reset structure.

[0054] When the toggle switch 400 is energized, the energy output can be controlled at any time via the jog switch 500. Specifically, when short-duration, precise operations are required, such as fine processing of localized areas during cutting or grinding, the user only needs to continuously press the jog switch 500 to keep the ultrasonic generator 200 on; releasing the jog switch 500 immediately shuts off the ultrasonic generator 200. This design enables precise control of the ultrasonic generator 200, improving operational accuracy, avoiding unnecessary processing errors, extending the service life of the ultrasonic generator 200, and reducing the risk of injury to the user due to accidental contact with the cutting head 300 during cutting and grinding.

[0055] See Figure 8 As shown, in some embodiments, the handle housing 110 has a mounting groove 114 at one end near the cutter head 300, with the opening of the mounting groove 114 facing the cutter head 300. The ultrasonic cutter 10 also includes a light 600, which is connected to the handle housing 110 via the mounting groove 114. For example, the light 600 can be an LED, which is fixed in the mounting groove 114 with adhesive and connected to the circuit. Four light 600s are provided, evenly distributed around the cutter head 300. In dimly lit working environments, the light 600s illuminate the cutter head 300 and the target object, allowing the user to more clearly observe the cutting or grinding area, improving operational visibility, enhancing work quality and efficiency, and reducing operational errors caused by poor visibility. In addition, since the high-frequency ultrasonic waves cause the blade head 300 to vibrate too fast, the working status of the blade head 300 cannot be seen with the naked eye. Therefore, the light 600 can also be used to show the working status of the ultrasonic blade 10. For example, when the jog switch 500 is pressed, the light 600 lights up, thus providing clearer feedback to the user so that the user knows that the ultrasonic blade 10 is working, which helps to improve work efficiency.

[0056] It should be understood that in other alternative embodiments, the number of light-emitting lamps 600 may also be one, two, three, five, six, etc.

[0057] See Figure 2 and Figure 7 As shown, in some embodiments, the ultrasonic cutter 10 also includes a display screen 700, such as an OLED display screen. The display screen 700 is connected to the handle housing 110 and to the ultrasonic generator 200 via a data cable. The display screen 700 is configured to display the operating status of the ultrasonic generator 200. Thus, the display screen 700 can display the operating frequency, power, and other operating status of the ultrasonic generator 200 in real time, allowing the user to easily understand the operation of the ultrasonic cutter 10 and adjust the operating method accordingly.

[0058] Optionally, in some embodiments, a temperature sensor is provided inside the handle housing 110 of the ultrasonic cutter 10 to monitor the ambient temperature of the ultrasonic generator 200. Correspondingly, the display screen 700 can be designed with a main and secondary screen that cycle through content. The main screen can display the real-time operating status of the toggle switch 400 and the jog switch 500 in animation form, while the secondary screen displays the real-time temperature to help prevent the ultrasonic cutter 10 from overheating.

[0059] See Figure 7 As shown, in some embodiments, the ultrasonic cutter 10 further includes a battery 800 and a charging port 900. The battery 800 is connected to the handle housing 110 and electrically connected to the ultrasonic generator 200. The charging port 900 is disposed on the handle housing 110 and electrically connected to the battery 800. For example, the battery 800 can be a lithium battery that supports PD protocol charging. The battery 800 can be charged and discharged simultaneously during use to power components such as the ultrasonic generator 200. The inclusion of the battery 800 and the charging port 900 frees the ultrasonic cutter 10 from the constraints of a power cord, making charging convenient. It also allows for the storage of electrical energy, enabling the ultrasonic cutter 10 to be carried for field operations, thus improving its applicability. Furthermore, integrating components such as the battery 800 into the handle housing 110 helps reduce the weight and size of the ultrasonic cutter 10, further enhancing its portability and flexibility.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
