Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, and in particular to an ultrasonic tool holder, ultrasonic processing equipment and machine tool. Background Technology

[0002] Ultrasonic machining generally involves applying voltage or current to an ultrasonic tool holder using an ultrasonic generator, causing the ultrasonic vibration element within it to vibrate at high frequency, which in turn drives the tool mounted on the ultrasonic tool holder to vibrate, thereby performing machining.

[0003] The transducer in an ultrasonic scalpel handle is prone to overheating during high-power output. Overheated transducers require shutdown for cooling, causing the ultrasonic scalpel handle to malfunction. Therefore, some existing ultrasonic scalpel handles incorporate external cooling structures to reduce the heat generated during high-power output. However, the cooling airflow delivered by these structures typically enters the internal cavity of the transducer housing through the side wall. Inside this cavity, the piezoelectric transducer is held and fixed by front and rear cover plates. Consequently, after entering the cavity with the help of intake pressure, the cooling airflow mostly flows to the rear end of the piezoelectric transducer, i.e., the rear cover plate, before filling the entire cavity and finally exiting. This results in slow airflow within the cavity, failing to effectively dissipate the heat generated by the transducer and impacting its operating efficiency. Utility Model Content

[0018] In some embodiments, the sealing cover, the housing assembly, and the bearing form a gap space, and a sealing fit is provided between the first channel and the gap space to separate the first channel from the gap space.

[0019] In some embodiments, the housing assembly is provided with a pressure relief hole communicating with the gap space, the pressure relief hole being connected to the outside of the housing assembly to discharge gas in the gap space.

[0020] In some embodiments, the transducer housing has an air inlet extending into the interior of the transducer housing at one end facing the bearing, and an exhaust port arranged through the periphery of the transducer housing, wherein the air inlet and the exhaust port are connected to the cooling channel.

[0031] Compared with the prior art, the ultrasonic tool holder, ultrasonic processing equipment, and machine tool implemented in this utility model have the following advantages:

[0032] The ultrasonic scalpel handle of this invention features a first cooling air path that cools the transducer, reducing its heat generation and preventing overheating that could malfunction the ultrasonic scalpel handle. Furthermore, the first cooling air path connects to a cooling channel at the rear end of the transducer, allowing the cool air from the first cooling air path to flow into the cooling channel and then through the transducer along the axial direction of the scalpel body. This ensures a consistent flow rate of the cool air within the transducer housing, effectively carrying away the heat generated by the transducer and preventing it from entering the inner cavity from the side wall of the transducer housing, where the cool air would then be redirected and lose flow rate.

[0033] Furthermore, the ultrasonic scalpel handle of this invention is equipped with an airflow turbine in the first channel, which allows the cold air in the first channel to quickly enter the transducer housing, effectively improving the cooling effect of the transducer. In addition, the ultrasonic scalpel handle is provided with a sealing cover plate to separate the first channel and the gap space, so as to prevent the airflow from carrying away the grease in the bearing, thereby extending the service life of the ultrasonic scalpel handle.

[0034] Furthermore, the ultrasonic scalpel holder of this invention has independent first and second air intake channels, which make the first cooling air path and the second cooling air path independent of each other and do not interfere with each other. In this way, the ultrasonic scalpel holder of this invention can independently supply air to the transducer and the scalpel according to the heat generation of the transducer and the scalpel, and achieve independent cooling of the transducer and the scalpel.

[0035] This utility model also provides an ultrasonic processing equipment and machine tool, which uses the aforementioned ultrasonic tool holder and has the aforementioned beneficial effects of the ultrasonic tool holder. Attached Figure Description

[0062] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0063] In the description of this utility model, it should be understood that when an element is referred to as "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to or indirectly connected to the other element. The terms "mounted," "connected," and "attached" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0064] In the description of this utility model, it should be understood that the terms "height," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer" used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0065] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0066] Example

[0067] refer to Figure 1-24 This utility model provides an ultrasonic tool holder 100, wherein the end side of the ultrasonic tool holder 100 connected to the machining tool is called the front side / front end / forward side, and the opposite end side is called the rear side / rear end / rear side. The ultrasonic tool holder 100 includes a tool body 1, a transducer assembly 2, and a wireless receiving assembly 3. The tool body 1 is generally used to connect to the spindle of a machine tool. The transducer assembly 2 includes a transducer housing 2a and a transducer 2b. An inner cavity 2a1 is provided inside the transducer housing 2a to accommodate the transducer 2b. The tool body 1 is detachably connected to the transducer housing 2a and forms a mounting part 4 that retracts into the transducer housing 2a.

[0068] The ultrasonic scalpel handle 100 in this embodiment uses a wireless transmission component to transmit electrical signals. The wireless transmission component typically includes a wireless transmitting component (not shown in the figure) and a wireless receiving component 3. As an example, the wireless transmitting component typically has a transmitting magnet and a transmitting coil. The transmitting coil is disposed inside the transmitting magnet. By passing an electrical signal to the transmitting coil, the transmitting magnet can generate a magnetic field. The wireless receiving component 3 typically has a receiving magnet and a receiving coil (not shown in the figure). The receiving magnet receives the magnetic field generated by the transmitting magnet and, based on magneto-electric induction, causes the receiving coil to generate a current.

[0069] It should be noted that in existing technologies, ultrasonic scalpel handles that use wireless transmission for electrical signal transmission typically have a single, integrated handle body. In this application, considering factors such as dustproofing, drop protection, and transducer cooling, the ultrasonic scalpel handle 100 has an outer shell assembly 5 installed on the outer periphery of the handle body. This outer shell assembly 5 is used to cover part of the handle body structure or to install cooling air passages. The outer shell assembly 5 is fitted onto the outer periphery of the handle body via a bearing 8. When the ultrasonic scalpel handle 100 rotates at high speed, the heat generation of the bearing 8 needs to be considered. Therefore, the ultrasonic scalpel handle 100 mounts the bearing 8 onto a mounting portion 4 formed by the detachable connection between the scalpel body 1 and the transducer housing 2a. The size of the mounting portion 4 is smaller than the size of the transducer housing 2a adjacent to the mounting portion 4. This not only reduces the size of the bearing 8 and its heat generation but also does not affect the size of the transducer 2b. The design of this ultrasonic scalpel handle 100 will be described in detail below.

[0070] It is understandable that transducer 2b generally includes a piezoelectric vibrator 2b1, used to convert electromagnetic energy into mechanical energy. The amplitude transformer 42 mounted at the front end of transducer 2b is a component used to amplify the mechanical amplitude. Generally, the piezoelectric vibrator 2b1 is installed in the inner cavity 2a1, and the amplitude transformer 42 extends from the inner cavity 2a1 to the front side of transducer assembly 2, connecting with the machining tool 43. The specific working principle of transducer 2b is an existing design and will not be elaborated here. However, it is important to note that the performance of transducer assembly 2 is closely related to the size of transducer 2b, such as the size of the piezoelectric vibrator 2b1. Since the piezoelectric vibrator 2b1 is installed inside the inner cavity 2a1 of transducer housing 2a, the size of the inner cavity 2a1 inside transducer housing 2a generally reflects the performance of transducer assembly 2. Changing the size of the inner cavity 2a1 will affect the performance of transducer assembly 2, such as output power.

[0071] It should be noted that there are various ways to achieve a detachable connection between the blade body 1 and the transducer housing 2a, and therefore, there are also multiple ways to form the mounting part 4. Generally, the mounting part 4 is formed at the connection position between the blade body 1 and the transducer housing 2a, as long as it ensures that the blade body 1 and the transducer housing 2a can be detachably connected. For example, in the first preset case, a portion of the structure of the blade body 1 is detachably connected to a portion of the structure of the transducer housing 2a to form the mounting part 4. In this case, the mounting part 4 includes a portion of the structure of the blade body 1 and a portion of the structure of the transducer housing 2a. Of course, in this preset case, since the mounting part 4 includes a portion of the structure of the blade body 1, the layout of the mounting part 4 being constricted within the transducer housing 2a will result in the outer diameter of the mounting part 4 being smaller than the outer diameter of other parts of the transducer housing 2a adjacent to the mounting part 4.

[0072] Alternatively, in the second preset scenario, the front end of the blade body 1 is provided with a detachable connecting structure, and the rear end of the transducer housing 2a is also provided with a detachable connecting structure. The two connecting structures are detachably connected to each other, which also enables a detachable connection between the blade body 1 and the transducer housing 2a, thereby forming the mounting part 4. Of course, in this preset scenario, the connecting structure is an additional structure independent of the blade body 1 and the transducer housing 2a. The mounting part 4 is recessed within the transducer housing 2a, resulting in the outer diameter of the connecting structure being smaller than the outer diameter of the transducer housing 2a adjacent to the mounting part 4.

[0073] Alternatively, in the third preset scenario, a detachable connecting structure is provided at the front end of the blade body 1 or the rear end of the transducer housing 2a. This connecting structure is detachably connected to the transducer housing 2a or the blade body 1 without a connecting structure, thus achieving a detachable connection between the blade body 1 and the transducer housing 2a, thereby forming the mounting part 4. In this preset scenario, the connecting structure is also an additional structure independent of the blade body 1 and the transducer housing 2a. The mounting part 4 is recessed within the transducer housing 2a, resulting in the outer diameter of the connecting structure being smaller than the outer diameter of the transducer housing 2a adjacent to the mounting part 4.

[0074] The ultrasonic scalpel handle 100 of this embodiment will be further described below using the first preset case as an example.

[0075] refer to Figure 2-4As an example of this embodiment, the transducer housing 2a is a cylindrical structure, which includes a housing portion 2a2 and a second protrusion 2a3 arranged sequentially along its own axial direction. The housing portion 2a2 is located in front of the second protrusion 2a3, and an inner cavity 2a1 is provided inside the housing portion 2a2 to accommodate the transducer 2b. The second protrusion 2a3 extends toward the rear end of the transducer housing 2a, and the outer diameter of the second protrusion 2a3 is smaller than the outer diameter of the housing portion 2a2, so that the second protrusion 2a3 forms a structure that protrudes from the rear side of the housing portion 2a2. In this way, the inner cavity 2a1 is always disposed inside the housing portion 2a2, and the change in the size of the second protrusion 2a3 will not affect the size of the inner cavity 2a1, so that the performance of the transducer 2b is guaranteed.

[0076] The cutter body 1 is coaxially arranged with the transducer housing 2a. The cutter body 1 has a first protrusion 1a and a body portion 1b arranged sequentially along its own axial direction. The body portion 1b is the main structure of the cutter body 1 and is used to connect to the spindle of the machine tool. The first protrusion 1a is located in front of the body portion 1b, and the outer diameter of the first protrusion 1a is smaller than the outer diameter of the portion of the body portion 1b adjacent to the mounting portion 4. The first protrusion 1a and the second protrusion 2a3 are detachably connected, thereby allowing the cutter body 1 to be detachably connected to the transducer housing 2a, thus forming the mounting portion 4 at the connection between the first protrusion 1a and the second protrusion 2a3.

[0077] It is understood that the blade body 1 in this embodiment is a shaft structure. Since the blade body 1 is coaxially arranged with the transducer housing 2a, and the first protrusion 1a of the blade body 1 is connected to the second protrusion 2a3 of the transducer housing 2a, when this ultrasonic blade holder 100 is used to process materials, the main body 1b of the blade body 1 is connected to the spindle of the machine tool, so that the blade body 1 can be driven by the spindle to rotate, thereby enabling the transducer assembly 2 connected to the first protrusion 1a and the processing tool 43 to rotate synchronously and perform processing actions.

[0078] It should be noted that the first protrusion 1a and body portion 1b of the blade body 1, and the housing portion 2a2 and second protrusion 2a3 of the transducer housing 2a, are only used to illustrate the detachable connection between the blade body 1 and the transducer housing 2a. The housing portion 2a2 and the second protrusion 2a3, and the body portion 1b and the first protrusion 1a are not limited to an integral structure. In other preset cases, the housing portion 2a2 and the second protrusion 2a3, and the body portion 1b and the first protrusion 1a can also be separate two-section structures. In specific applications, the structure of the blade body 1 and the transducer housing 2a can be selected to adopt an integral connection structure or a segmented structure, depending on the application scenario.

[0079] It should be noted that the mounting part 4, formed by the nesting and mutual cooperation of the first protrusion 1a and the second protrusion 2a3, has at least two implementation methods:

[0080] Firstly, refer to Figure 2 The outer diameter of the first protrusion 1a is larger than the outer diameter of the second protrusion 2a3. A first mounting hole 1a1 is provided inside the blade body 1, which passes through the first protrusion 1a and the body part 1b along the axial direction (i.e., the front-rear direction) of the blade body 1. The inner wall of the first mounting hole 1a1 protrudes towards the inside of the first mounting hole 1a1 to form a limiting ring 1a10. The second protrusion 2a3 extends rearward along the axial direction of the blade body 1, and a second mounting hole 2a4 is provided inside the second protrusion 2a3, which extends along the axial direction of the blade body 1. The second protrusion 2a3 extends into the first mounting hole 1a1 and is located in front of the limiting ring 1a10. The limiting ring 1a10 restricts the position of the second protrusion 2a3 in the axial direction of the blade body 1, so that the second protrusion 2a3 is installed in the first mounting hole 1a1. The first protrusion 1a wraps around the outer periphery of the second protrusion 2a3, thereby forming the connection between the second protrusion 2a3 and the first protrusion 1a, i.e., the mounting part 4.

[0081] Secondly, refer to Figure 3-4 The outer diameter of the first protrusion 1a is smaller than the outer diameter of the second protrusion 2a3. The first protrusion 1a extends forward along the axial direction of the blade body 1, and a first mounting hole 1a1 is provided inside the blade body 1, which passes through the first protrusion 1a and the body part 1b along the axial direction of the blade body 1. The second protrusion 2a3 extends backward along the axial direction of the blade body 1, and a second mounting hole 2a4 is provided in the transducer housing 2a, which extends along the axial direction of the blade body 1. The second mounting hole 2a4 is a stepped hole, which includes a large-diameter section 2a40 and a small-diameter section 2a41 that are interconnected. The first protrusion 1a is installed in the large-diameter section 2a40 of the second mounting hole 2a4, so that the second protrusion 2a3 wraps around the outer periphery of the first protrusion 1a, and forms the connection between the second protrusion 2a3 and the first protrusion 1a, i.e., the mounting part 4.

[0082] In this embodiment, when the ultrasonic scalpel handle 100 is in operation, the scalpel body 1 can drive the transducer housing 2a to rotate and rise. Therefore, the scalpel body 1 and the transducer housing 2a need to be locked and fixed in the axial direction of the scalpel body 1. Figure 2 , 6In the structure shown in Figure -9, as an example of this embodiment, a locking member 41 is provided in the first mounting hole 1a1. The locking member 41 passes through the limiting ring 1a10 along the axial direction of the blade body 1, extends into the second mounting hole 2a4, and is tightly connected to the second protrusion 2a3 of the transducer housing 2a, so as to realize the detachable connection between the first protrusion 1a and the second protrusion 2a3. Furthermore, the outer peripheral surface of the second protrusion 2a3 can be set as a conical surface, and correspondingly, the inner peripheral surface of the first protrusion 1a is also set as a conical surface. In this way, when the locking member 41 locks the first protrusion 1a and the second protrusion 2a3, the outer peripheral surface of the second protrusion 2a3 can be tightly fitted with the inner peripheral surface of the first protrusion 1a, so that the first protrusion 1a and the second protrusion 2a3 are tightly connected.

[0083] Of course, in Figure 3-4 In the structure shown, the locking member 41 has a different engagement method with the first protrusion 1a and the second protrusion 2a3. (Reference) Figure 3-4 7. As an example of this embodiment, a locking member 41 is provided in the first mounting hole 1a1. The locking member 41 penetrates the first protrusion 1a along the axial direction of the blade body 1 and extends into the small-diameter section 2a41 of the second mounting hole 2a4, and is tightly connected to the second protrusion 2a3 to achieve a detachable connection between the first protrusion 1a and the second protrusion 2a3. At this time, the outer peripheral surface of the first protrusion 1a can be set as a conical surface. Correspondingly, the inner peripheral surface of the large-diameter section 2a40 of the second mounting hole 2a4 is also set as a conical surface. In this way, when the locking member 41 locks the first protrusion 1a and the second protrusion 2a3, the outer peripheral surface of the first protrusion 1a can be tightly fitted with the inner peripheral surface of the large-diameter section 2a40 of the second mounting hole 2a4, so that the first protrusion 1a and the second protrusion 2a3 are tightly connected.

[0084] Of course, the locking member 41 can also be installed in the second mounting hole 2a4, but it is more complicated to disassemble than when it is installed in the first mounting hole 1a1. Since the transducer 2b is installed in the inner cavity 2a1 of the housing 2a2, if the locking member 41 is set in the second mounting hole 2a4 on the transducer housing 2a side, when it is necessary to disassemble the blade 1 from the transducer housing 2a, the transducer 2b must be removed first, and then the locking member 41 must be loosened from the second mounting hole 2a4 to disassemble the blade 1 from the transducer housing 2a. However, if the locking member 41 is installed in the first mounting hole 1a1 on the blade 1 side, when the ultrasonic scalpel 100 is removed from the spindle, the locking member 41 can be loosened directly to disassemble the blade 1 from the transducer housing 2a.

[0085] It is important to note that the mounting portion 4, formed under different conditions, will always be concave within the transducer housing 2a. That is, the outer diameter of the mounting portion 4 will be smaller than the outer diameter of other locations on the transducer housing 2a adjacent to the mounting portion 4. This results in the blade body 1 and the transducer housing 2a, which are connected to each other, having a recessed profile at the location of the mounting portion 4. Consequently, a mounting space, such as an annular groove, is typically formed at the location of the mounting portion 4. Utilizing this annular groove, the ultrasonic scalpel handle 100 mounts a bearing 8 on the mounting portion 4, and mounts a housing assembly 5 on the bearing 8. The housing assembly 5 is arranged on the outer periphery of the scalpel handle body. With the cooperation of the housing assembly 5, the dustproof and shockproof effects of the transducer housing 2a and the transducer 2b are improved, protecting the transducer housing 2a and its internal transducer 2b from external influences.

[0086] In this embodiment, the ultrasonic scalpel handle 100 uses a wireless transmission component to transmit electrical signals. The wireless transmitting component and the wireless receiving component 3 are typically arranged vertically or internally. (See reference...) Figure 6-24 In this embodiment, the ultrasonic scalpel handle 100 will be further described with the wireless transmitting component and the wireless receiving component 3 arranged in an up-down configuration.

[0087] Since the wireless transmitting component and the wireless receiving component 3 need to be arranged relative to each other and close to each other during the operation of the wireless transmission component, if the wireless receiving component 3 is arranged in the mounting part 4, it may hinder the cooperation of the wireless transmitting component. Therefore, in this embodiment, the ultrasonic scalpel handle 100 has the wireless receiving component 3 mounted on the body part 1b, located on the outer periphery of the scalpel body 1, and arranged on the rear side of the mounting part 4. By connecting the wireless receiving component 3 to the transducer 2b in the transducer housing 2a, the wireless transmission component can transmit electrical signals to the transducer 2b, enabling the transducer 2b to operate.

[0088] It should be noted that the wireless receiver 3 is connected to the outer periphery of the main body 1b and will rotate with the rotation of the blade 1. Therefore, the wireless receiver 3 and the outer shell assembly 5 are not in close contact. There is usually a certain gap between the front side of the wireless receiver 3 and the rear side of the outer shell assembly 5.

[0089] It should be noted that since the wireless receiver 3 is located at the rear of the mounting part 4, and the transducer 2b is located at the front of the mounting part 4, the wire between the wireless receiver 3 and the transducer 2b must pass through the mounting part 4. However, when the housing assembly 5 is mounted on the mounting part 4 via the bearing 8, the wire between the wireless receiver 3 and the transducer 2b is prone to interference with the housing assembly 5, potentially causing the wire to break. Therefore, refer to... Figure 2As an example of this embodiment, the ultrasonic scalpel handle 100 has a first electrical connection channel 6 inside the scalpel body 1, which extends to the outside of the scalpel body 1 to connect to the wireless receiving component 3; and the mounting part 4 has a second electrical connection channel 7, one end of which connects to the first electrical connection channel 6, so that the first electrical connection channel 6 and the second electrical connection channel 7 form an electrical connection path.

[0090] It should be noted that since locking members 41 are usually installed inside the first protrusion 1a and the second protrusion 2a3, making it inconvenient to arrange wire channels, the second electrical connection channel 7 is usually arranged extending along the axial direction of the blade body 1 and close to the outer edge of the mounting part 4. However, the arrangement position of the second electrical connection channel 7 will vary depending on the way the mounting part 4 is formed. For example, when the first protrusion 1a wraps around the outer periphery of the second protrusion 2a3, the second electrical connection channel 7 will be arranged inside the first protrusion 1a, while when the second protrusion 2a3 wraps around the outer periphery of the first protrusion 1a, the second electrical connection channel 7 will be arranged inside the second protrusion 2a3.

[0091] It should be noted that the electrical connection path formed by the second electrical connection channel 7 and the first electrical connection channel 6 communicates with the inner cavity 2a1 inside the transducer housing 2a. This communication can be direct or indirect. For example, when the first protrusion 1a encloses the outer periphery of the second protrusion 2a3, the second electrical connection channel 7 is arranged inside the first protrusion 1a. In this case, the transducer housing 2a has a through hole that mates with the second electrical connection channel 7, allowing the second electrical connection channel 7 to communicate with the inner cavity 2a1 inside the transducer housing 2a. Alternatively, when the second protrusion 2a3 encloses the outer periphery of the first protrusion 1a, the second electrical connection channel 7 is arranged inside the second protrusion 2a3. In this case, the first electrical connection channel 6 can be a groove structure formed at the front end of the blade body 1, allowing the first electrical connection channel 6 to communicate directly with the second electrical connection channel 7. Alternatively, the first electrical connection channel 6 can be indirectly connected to the second electrical connection channel 7 through a hole structure or channel structure formed inside the blade body 1.

[0092] Or, for example, refer to Figure 2When the first protrusion 1a wraps around the outer periphery of the second protrusion 2a3, the second protrusion 2a3 is embedded in the first protrusion 1a, so that the first protrusion 1a and the second protrusion 2a3 form the mounting part 4. At this time, the second electrical connection channel 7 is arranged in the first protrusion 1a and extends to the front end of the blade body 1. Furthermore, a third electrical connection channel 11 extending along the axial direction of the transducer housing 2a is provided in the transducer housing 2a. The third electrical connection channel 11 communicates with the second electrical connection channel 7 and connects to the interior of the transducer housing 2a, i.e., the inner cavity 2a1. At this time, the electrical connection path formed by the second electrical connection channel 7 and the first electrical connection channel 6 communicates with the inner cavity 2a1 through the third electrical connection channel 11. It should be noted that the second electrical connection channel 7 and the third electrical connection channel 11 do not necessarily extend along the axial direction. Axial extension is only one case. In other ultrasonic scalpel handles 100, the second electrical connection channel 7 and the third electrical connection channel 11 can also be inclined to the axial direction of the scalpel body 1, so that they can also be connected to the inner cavity 2a1.

[0093] Considering that the blade body 1 and the transducer housing 2a are detachably connected, there is a possibility of separation between the transducer housing 2a and the blade body 1. To facilitate rapid connection between the wireless receiving component 3 and the transducer 2b during the disassembly and reassembly of the transducer housing 2a and the blade body 1, the conductive components located in the electrical connection path and the third electrical connection channel 11 are preferably connected by a plug-in joint. (Reference) Figure 6-7 In the ultrasonic scalpel holder 100, Figure 2 In the shown mating structure, the ultrasonic scalpel handle 100 includes a first conductive element 9 and a second conductive element 10. The first conductive element 9 is disposed in the second electrical connection channel 7 and is electrically connected to the wireless receiving component 3. The second conductive element 10 is disposed in the third electrical connection channel 11 and can form a plug-in mating with the first conductive element 9. The second conductive element 10 is also electrically connected to the transducer 2a. In this way, when the transducer housing 2a is separated from the scalpel body 1, the first conductive element 9 and the second conductive element 10 can be separated and move with the scalpel body 1 and the transducer housing 2a respectively. The wires between the wireless receiving component 3 and the first conductive element 9, and between the transducer 2b and the second conductive element 10, do not need to be broken. When the transducer housing 2a is assembled with the scalpel body 1, the first conductive element 9 and the second conductive element 10 can be plugged in, allowing the wireless receiving component 3 to communicate with the transducer 2b.

[0094] When the gap between transducer 2b and transducer housing 2a is small, electrical sparks can easily be generated inside the inner cavity 2a1. Therefore, an insulating structure can be arranged between transducer 2b and transducer housing 2a to prevent electrical sparks. (Reference) Figure 6 , 9-10. As an example of this embodiment, an insulating member 12 is provided inside the transducer housing 2a. The insulating member 12 is arranged on the outer periphery of the transducer 2b, and the transducers 2b are arranged at intervals. Furthermore, in order to prevent the wires between the transducer 2b and the wireless receiving component 3 from entering the gap between the transducer 2b and the transducer housing 2a and causing electrical sparks, a wire groove 15 can be opened on the outer side of the insulating member 12. The wire groove 15 is connected to the inner side of the insulating member 12, and the wire groove 15 is connected to the third electrical connection channel 11 and the second electrical connection channel 7. In this way, after the wires between the transducer 2b and the wireless receiving component 3 enter the inner cavity 2a1, they will enter the wire groove 15 and extend along the wire groove 15. At this time, the wires and the transducer 2b are separated by the insulating member 12, ensuring the safety of the wires arranged inside the transducer housing 2a.

[0095] It should be noted that the wire between transducer 2b and wireless receiver 3 is connected to the wiring port of transducer 2b. Therefore, the wire can extend along the wire groove 15 to a position directly opposite the wiring port before entering the inside of the insulating member 12 and connecting to transducer 2b. Thus, the position where the wire groove 15 connects to the inside of the insulating member 12 is usually the location of the wiring port of transducer 2b. This also helps to shorten the length of the wire entering the inside of the insulating member 12, ensuring its safety. The wire groove 15 can be connected to the inside of the insulating member 12 through a through-hole structure, or the wire groove 15 itself can extend to the inside of the insulating member 12; this will not be illustrated in the accompanying drawings.

[0096] Of course, the insulating element 12 can also cover the rear side of the transducer 2b. For example, the transducer 2b typically has a piezoelectric oscillator 2b1, and see [reference needed]. Figure 10 The insulating member 12 can extend to the rear side of the piezoelectric vibrator 2b1, thereby enclosing the piezoelectric vibrator 2b1. In this case, the wire groove 15 can extend from the rear end of the piezoelectric vibrator 2b1 to the outer periphery of the piezoelectric vibrator 2b1, and the projections of the first conductive member 9 and the second conductive member 10 in the axial direction of the blade body 1, i.e., the front-to-back direction, are located within the wire groove 15, so that after the wire between the transducer 2b and the wireless receiving assembly 3 enters the inner cavity 2a1, it can enter the wire groove 15 along the axial direction of the blade body 1, thereby controlling the length of the wire inside the inner cavity 2a1.

[0097] In some ultrasonic scalpel holders 100, considering that the transducer 2b is prone to overheating during operation, which may affect the normal operation of the ultrasonic scalpel holder 100, a cooling structure may be provided in the ultrasonic scalpel holder 100. For example, a first cooling air passage 14 connected to an external cooling air source is provided inside the outer shell assembly 5, and the first cooling air passage 14 is connected to the inner cavity 2a1. By connecting the external cooling air source to the first cooling air passage 14, the cold air enters the inner cavity 2a1 at the rear end of the transducer 2b along the first cooling air passage 14, thereby cooling the transducer 2b located inside the transducer shell 2a.

[0098] The first cooling air passage 14 is connected to the inner cavity 2a1 at the rear end of the transducer 2b, which allows the cold air from the first cooling air passage 14 to enter the inner cavity 2a1 in the flow direction and pass through the transducer 2b along the axial direction of the blade body 1. This ensures the flow rate of the cold air in the transducer housing 2a, and promptly removes the heat generated by the transducer 2b, preventing it from entering the inner cavity 2a1 from the side wall of the transducer housing 2a. Consequently, the cold air would turn around in the transducer housing 2a, resulting in a loss of flow rate.

[0099] Specifically, the piezoelectric vibrator 2b1 is usually stacked inside the transducer housing 2a along the axial direction of the cutter body 1. Therefore, when the gas enters the transducer housing 2a through the rear end of the transducer housing 2a, the gas flow direction and the stacking direction of the piezoelectric vibrator 2b1 are both parallel to the axial direction of the cutter body 1. The gas can pass through the piezoelectric vibrator 2b1 along the flow direction, reducing the energy loss of the gas inside the transducer housing 2a and enabling the gas to carry away more heat from the piezoelectric vibrator 2b1.

[0100] The first cooling air passage 14 needs to be connected to an external cooling air source, which is usually achieved by using an air pipe or air channel. In order to avoid the air pipe or air channel from becoming tangled when the ultrasonic scalpel handle 100 rotates at high speed, the outer shell assembly 5 is generally kept stationary relative to the scalpel body 1 and the transducer housing 2a. Therefore, the outer shell assembly 5 uses a bearing 8 as the connection structure for assembly, and the bearing 8 is sleeved on the outer periphery of the scalpel body 1 and / or the transducer housing 2a.

[0101] It is understandable that the rear side of the transducer housing 2a and the front side of the bearing 8 are usually spaced apart and not in contact, which avoids friction between the transducer housing 2a and the bearing 8 during rotation. Of course, in the case where a bearing cap 21 is provided on the front side of the bearing 8, the rear side of the transducer housing 2a will be spaced apart from the front side of the bearing cap 21, and the bearing cap 21 can provide a limiting seal for the bearing 8. Therefore, the first cooling air passage 14 connecting to the inner cavity 2a1 of the transducer housing 2a may be connected to the bearing 8, affecting the bearing 8 and potentially increasing the air pressure in the space where the bearing 8 is located, leading to the loss of lubricating grease inside the bearing 8. The performance of the bearing 8 will severely affect the service life of the ultrasonic scalpel handle 100. For this, refer to... Figure 6-14A sealing cover plate 44 is installed on the outer side of the transducer housing 2a. The sealing cover plate 44 is arranged at the front end of the bearing 8 and is located at the rear end of the inner cavity 2a1. The outer shell assembly 5 extends to the outer periphery of the transducer housing 2a, so that the transducer housing 2a, the sealing cover plate 44 and the outer shell assembly 5 form a first channel 14a. The first cooling air passage 14 is connected to the inner cavity 2a1 through the first channel 14a.

[0102] Guided by the first channel 14a, the cold air supplied by the external cooling air source can flow into the inner cavity 2a1 after leaving the first cooling air path 14a. The first cooling air path 14a is not directly connected to the space where the bearing 8 is located, thereby avoiding an increase in the air pressure in the space where the bearing 8 is located.

[0103] It should be noted that by providing a sealing cover plate 44 between the transducer housing 2a and the bearing 8, the cavity formed by the transducer housing 2a, the bearing 8 and the outer shell assembly 5 is divided into a gap space 20 and a first channel 14a. That is, the sealing cover plate 44, the outer shell assembly 5 and the bearing 8 form the gap space 20, and the sealing cover plate 44, the outer shell assembly 5 and the transducer housing 2a form the first channel 14a. The cold air in the first cooling air passage 14 mainly enters the first channel 14a, and then enters the interior of the transducer housing 2a through the first channel 14a to cool the transducer 2b. That is, the first cooling air passage 14 and the interior of the transducer housing 2a are connected through the first channel 14a.

[0104] Understandably, to prevent cold air in the first channel 14a from entering the gap space 20 and affecting the bearing 8, a sealing fit is provided between the first channel 14a and the gap space 20 to separate the first channel 14a from the gap space 20. For example, as an example of this embodiment, refer to... Figure 6-7 17. A seal is provided between the sealing cover plate 44 and the outer casing assembly 5 to seal and isolate the first channel 14a from the gap space 20.

[0105] Of course, considering that the transducer housing 2a and the bearing outer sleeve 5a will rotate relative to each other during the high-speed rotation of the ultrasonic scalpel holder 100, if the sealing effect of the seal is too good, it will easily lead to friction between the transducer housing 2a and the seal, generating a lot of heat. Therefore, the seal can be made of polytetrafluoroethylene to reduce rotational friction. However, this will result in a small gap between the transducer housing 2a and the seal, allowing some cold air to enter the gap space 20, causing an increase in the air pressure in the space where the bearing 8 is located, leading to the loss of lubricating grease inside the bearing 8. For this, refer to... Figure 7 , 11As an example of this embodiment, the outer shell assembly 5 is provided with a pressure relief hole 22 that communicates with the gap space 20. The pressure relief hole 22 passes through the outer shell assembly 5 and communicates with the outside of the outer shell assembly 5 to discharge the gas in the gap space 20.

[0106] Understandably, gas flow rate is one of the main factors affecting gas cooling; increasing the flow rate of the cold gas inside the transducer housing 2a is beneficial for heat dissipation from the transducer 2b. For this, refer to... Figure 6 , 13 As one way to increase the flow speed of cold air inside the transducer housing 2a, an airflow turbine 19 is connected to the outside of the transducer housing 2a, so that the airflow turbine 19 is fixed relative to the transducer housing 2a, and the airflow turbine 19 is set in the first channel 14a and rotates synchronously with the transducer housing 2a, thereby driving the airflow in the first channel 14a into the transducer housing 2a.

[0107] The airflow turbine 19 includes multiple turbine blades 19a, which are spaced circumferentially along the transducer housing 2a and are in contact with the transducer housing 2a to form a turbine structure. By providing the airflow turbine 19, when the ultrasonic scalpel handle 100 rotates at high speed, the airflow turbine 19 can rotate at high speed along with the transducer housing 2a, thereby drawing the airflow from the first channel 14a into the interior of the transducer housing 2a. This accelerates the entry of cold air into the interior of the transducer housing 2a, resulting in a faster flow rate of the cold air through the interior of the transducer housing 2a, thus improving the heat dissipation effect of the cold air on the transducer 2b.

[0108] The piezoelectric vibrators 2b1 of the transducer 2b are typically stacked along the axial direction of the blade body 1. Therefore, when the cold air from the first channel 14a enters the inner cavity 2a1, it can pass through the piezoelectric vibrators 2b1 in the flow direction. In this case, the cold air flow rate in the inner cavity 2a1 is optimal, and there is no need to turn within the inner cavity 2a1, resulting in flow rate loss. To achieve this, the air inlet 16a of the transducer housing 2a needs to be located at the top of the transducer housing 2a. Therefore, as an example of this embodiment, the end of the transducer housing 2a facing the sealing cover plate 44 is provided with multiple air inlets 16a that extend into the inner cavity 2a1. Furthermore, there is at least one air inlet 16a between two adjacent turbine blades 19a, so that the cold air in the first channel 14a can be driven by the airflow turbine 19 and enter the inner cavity 2a1 more evenly to cool the transducer 2b. Furthermore, the airflow turbine 19 can distribute the cold air inside the first channel 14a to the air inlet 16a more evenly, preventing the cold air from forming turbulence in the inner cavity 2a1 and causing energy loss.

[0109] refer to Figure 13The airflow turbine 19 can adopt a turbine structure layout and be fixedly connected to the rear side of the transducer housing 2a by bolts or other structures, and fit snugly against the transducer housing 2a. It should be noted that the airflow turbine 19 and the transducer housing 2a are designed separately, which is beneficial for the machining of the airflow turbine 19. Of course, as an example of this embodiment, the airflow turbine 19 and the sealing cover plate 44 are integrally formed, which allows the two to be fixedly installed on the transducer housing 2a simultaneously, thereby omitting an assembly step.

[0110] Of course, when the ultrasonic scalpel handle 100 rotates at high speed, the bearing 8 is also prone to generating a lot of heat, which can cause the bearing 8 to overheat and affect its service life. Therefore, in this embodiment, the ultrasonic scalpel handle 100 utilizes the mounting space formed by the mounting part 4 to allow the outer shell assembly 5 to be sleeved on the mounting part 4 through the bearing 8. In this way, the outer diameter of the bearing 8 can be smaller than the outer diameter of the shell part 2a2 or the outer diameter of the body part 1b, so that the size of the bearing 8 can be controlled. Moreover, the outer shell assembly 5 can be arranged using the mounting space formed by the mounting part 4, which can reduce the space occupied by the outer shell assembly 5 on the outside of the scalpel body 1 and the transducer housing 2a, and make the first cooling air passage 14 closer to the transducer housing 2a. The distance of the cold air input from the external cooling air source to the inside of the transducer housing 2a is shorter, reducing the loss of cold air during the flow process and increasing the flow rate of the cold air entering the inside of the transducer housing 2a, so that the heat generated by the transducer 2b can be more easily carried away.

[0111] It should be noted that in the relevant solutions involving the cooling structure, the blade body 1 and the transducer housing 2a of the ultrasonic scalpel holder 100 are not necessarily designed to be detachable; the blade body 1 and the transducer housing 2a can also be an integral structure. In the ultrasonic scalpel holder 100, the blade body 1 and the transducer housing 2a are usually collectively referred to as the scalpel holder body. When the scalpel holder body is an integral structure, the blade body 1 and the transducer housing 2a are connected to each other, but they are not detachable. In these ultrasonic scalpel holders 100, the outer housing assembly 5 can be sleeved on the outer periphery of the blade body 1, or on the outer periphery of the transducer housing 2a, or at the junction of the blade body 1 and the transducer housing 2a, i.e., on the outer periphery of the blade body 1 and the transducer housing 2a, using the bearing 8. Furthermore, in these ultrasonic scalpel holders 100, the first cooling air passage 14 provided in the outer housing assembly 5 can also be connected to the interior of the transducer housing 2a. The arrangement of the first cooling air passage 14 in connection with the transducer housing 2a is the same as that of the ultrasonic scalpel handle 100 in this embodiment, and will not be described in detail here.

[0112] It should be noted that, based on the two implementation methods of the mounting portion formed by the mutual cooperation of the first protrusion 1a and the second protrusion 2a3, the cooperation between the bearing 8 and the mounting portion 4 also has at least two methods. One is, referring to... Figure 6-7The inner ring of the bearing 8 is fitted onto the first protrusion 1a, thereby connecting and fixing the bearing 8 to the blade body 1. In this way, both the bearing 8 and the transducer housing 2a will use the blade body 1 as the assembly reference, effectively reducing the accumulation of errors caused by assembly, improving the assembly accuracy of the bearing 8, the outer housing assembly 5 and the transducer housing 2a, and making the ultrasonic scalpel handle 100 operate better in high-speed rotation. Secondly, the inner ring of the bearing 8 is fitted onto the second protrusion 2a3, thereby connecting and fixing the bearing 8 to the transducer housing 2a, which also enables the assembly of the bearing 8 with the mounting part 4.

[0113] When the ultrasonic scalpel holder 100 rotates at high speed, the inner ring of the bearing 8 rotates at high speed along with the scalpel body 1, causing a large amount of friction between the inner and outer rings of the bearing 8, resulting in severe heat generation in the bearing 8. Considering that the first cooling air passage 14 is located within the outer casing assembly 5, the bearing 8 can be cooled using the first cooling air passage 14. (Reference) Figure 6-14 As an example of this embodiment, the outer casing assembly 5 includes a bearing outer sleeve 5a and an airflow seat 5b. The bearing outer sleeve 5a is connected to the outer ring of the bearing 8 and extends to the outer periphery of the transducer housing 2a, forming a first channel 14a between the transducer housing 2a and the sealing cover plate 44. The airflow seat 5b is connected to the outer periphery of the bearing outer sleeve 5a and forms a second channel 14b between the bearing outer sleeve 5a and the bearing outer sleeve 5a. The first channel 14a and the second channel 14b are connected, and the airflow seat 5b has a first air intake channel 14c that is connected to an external cooling air source. The first air intake channel 14c and the second channel 14b are connected in sequence to form a first cooling air path 14.

[0114] The bearing outer sleeve 5a is usually made of metal. Therefore, the bearing outer sleeve 5a connected to the outer ring of the bearing 8 can absorb some of the heat generated by the bearing 8, thus playing a certain role in cooling the bearing 8. Furthermore, the cold air supplied by the external cooling air source enters the second channel 14b through the first air intake channel 14c. Since the bearing outer sleeve 5a and the air intake seat 5b form the second channel 14b, the cold air and the bearing outer sleeve 5a undergo the first heat exchange, which carries away the heat of the bearing outer sleeve 5a, thereby reducing the temperature of the bearing outer sleeve 5a and increasing the temperature difference between the bearing 8 and the bearing outer sleeve 5a. This further allows the heat generated by the bearing 8 to be absorbed by the bearing outer sleeve 5a, thus achieving the cooling of the bearing 8. Moreover, with the cooperation of the airflow turbine 19, when the ultrasonic scalpel handle 100 rotates at high speed, the airflow turbine 19 can rotate at high speed along with the transducer housing 2a. Under the action of the airflow turbine 19, the cold air will accelerate through the air inlet 16a, making the flow rate of the cold air faster, thereby further improving the heat dissipation effect of the cold air on the transducer 2b and making up for the cold loss that has already undergone one heat exchange before the cold air cools the transducer 2b.

[0115] Understandably, the temperature of the bearing outer sleeve 5a is a crucial factor determining the degree of heat exchange between the bearing outer sleeve 5a and the bearing 8. Therefore, when cold air passes through the bearing outer sleeve 5a, it is necessary to ensure that the cold air can sufficiently remove the heat from the bearing outer sleeve 5a. (Reference) Figure 12 As an example of this embodiment, a guide member 17 is provided in the second channel 14b. A guide air groove 18 communicating with the second channel 14b is provided on the guide member 17. The guide air groove 18 is spirally arranged on the outer side of the guide member 17 in the back-to-back direction, that is, the axial direction of the blade body 1 is the axial direction.

[0116] It is understandable that in the above example structure, the bearing outer sleeve 5a is connected to the outer ring of the bearing 8, forming a layout that surrounds the outer ring of the bearing 8. Therefore, the first channel 14a formed between the bearing outer sleeve 5a, the sealing cover plate 44, and the transducer housing 2a, which is the outer shell assembly 5, the bearing 8, and the sealing cover plate 44, is an annular space that surrounds the transducer housing 2a. Moreover, the airflow seat 5b is connected to the outer periphery of the bearing outer sleeve 5a, also forming a layout that surrounds the bearing outer sleeve 5a. Therefore, the second channel 14b formed between the airflow seat 5b and the bearing outer sleeve 5a is also an annular space. Therefore, by setting the air guide groove 18 in the guide member 17, the cold air leaving the second channel 14b will form a swirling flow. This will not only make the flow rate of the cold air in the first channel 14a faster, but also match the annular layout of the first channel 14a with the cold air flowing in a swirling manner. The first channel 14a will not obstruct the flow of the cold air inside it, making the flow rate of the cold air into the inner cavity 2a1 faster. In this way, the flow rate of the cold air through the transducer 2b will be further increased, so that the cold air can carry away more heat from the transducer 2b, thereby making up for the cold loss during the second heat exchange between the cold air and the transducer 2b.

[0117] refer to Figure 6 , 9 -10, as an example of this embodiment, in the case where an insulating member 12 is provided in the transducer housing 2a, the insulating member 12 is arranged on the outer periphery of the transducer 2b and spaced apart from the transducer 2b, thereby forming a cooling channel 13 between the insulating member 12 and the transducer 2b. The cooling channel 13 is connected to the inner cavity 2a1 and is connected to the first cooling air passage 14 through the air inlet 16a.

[0118] The insulating component 12 is made of insulating material, such as plastic steel. By using the insulating component 12 to form an insulating barrier between the transducer 2b and the transducer housing 2a, the need for wrapping insulating cloth around the outside of the transducer 2b is eliminated, thus avoiding interference with heat dissipation. Furthermore, through the cooling channel 13 between the insulating component 12 and the transducer 2b, cool air can flow from the first channel 14a to the cooling channel 13 to cool the transducer 2b. Moreover, the installation of the insulating component 12 helps to reduce the flow cross-sectional area around the transducer 2b, allowing cooling air to quickly pass through the cooling channel 13, further improving the cooling effect of the transducer 2b.

[0119] The cold air that has undergone the first heat exchange with the bearing housing 5a flows further to the first channel 14a and reaches the transducer 2b through the cooling channel 13, where it undergoes a second heat exchange, cooling the transducer 2b. Of course, to allow the cold air to enter and exit the transducer housing 2a, the transducer housing 2a will be equipped with corresponding perforated or channel structures. (Reference) Figure 14 As an example of this embodiment, the transducer housing 2a is provided with a through exhaust port 16b on its periphery. The air inlet 16a and the exhaust port 16b are connected to the interior of the transducer housing 2a to form a third cooling air passage 16. The third cooling air passage 16 is connected to the first cooling air passage 14 and the first channel 14a.

[0120] It should be noted that the first cooling air passage 14 is interconnected with the first channel 14a and the third cooling air passage 16, forming the internal cooling air passage of the ultrasonic scalpel handle 100. The cold air entering this internal cooling air passage through the first air inlet channel 14c will follow the guide of the first cooling air passage 14, the first channel 14a, and the third cooling air passage 16, passing in the forward direction through the bearing outer sleeve 5a, the transducer housing 2a, and the transducer 2b, undergoing a first heat exchange with the bearing outer sleeve 5a and a second heat exchange with the transducer 2b, before being discharged from the transducer housing 2a.

[0121] In some ultrasonic scalpel handles 100, the cross-sectional profile of the outer periphery of the transducer housing 2a is circular. In this case, the exhaust port 16b can be arranged along the tangent of the circle, which is conducive to the exhaust of cold air from the inner cavity 2a1.

[0122] In the structure of the ultrasonic scissor holder 100, an amplitude transformer 42 is typically connected to the front end of the transducer housing 2a, and the cutter 43 is connected to the front end of the amplitude transformer 42, using the amplitude transformer 42 to increase the amplitude of the cutter 43. During the process of the ultrasonic scissor holder 100 assembling a disc cutter to cut materials, the cutter 43 generates a large amount of heat when cutting the material, causing the material temperature to rise. This leads to the melting of the adhesive inside the material, which adheres to the cutter 43, or the chips generated during processing adhere to the cutter 43, affecting the subsequent processing effect. Therefore, this ultrasonic scissor holder 100 adds a cooling air structure for the cutter 43 to cool it during processing. Moreover, considering that the efficiency of the cooling air entering through the first air inlet channel 14c exchanging heat with the bearing outer sleeve 5a and the transducer 2b before exchanging heat with the cutter 43 is relatively low, this ultrasonic scissor holder 100 is also equipped with a second cooling air channel 27 independent of the first cooling air channel 14.

[0123] refer to Figure 16 As an example of this embodiment, the outer shell assembly 5 is provided with a first air guide pipe 29 and a second air guide pipe 30. The first air guide pipe 29 extends along the front-back direction, i.e., the axial direction of the cutter body 1. The second air guide pipe 30 is arranged circumferentially on the amplitude transformer 42 and communicates with the first air guide pipe 29. The outer shell assembly 5 is also provided with a second air inlet channel 27a that communicates with an external cooling air source. The second air inlet channel 27a, the first air guide pipe 29, and the second air guide pipe 30 are sequentially connected to form a second cooling air path 27. A nozzle 28 for cooling the cutter 43 can also be provided along the arrangement path of the second air guide pipe 30. The nozzle 28 is communicated with the second air guide pipe 30 to output cold air from the second cooling air path 27.

[0124] The first air guide tube 29 and the second air guide tube 30 are exposed and easily damaged by impact. To address this, the outer casing assembly 5 can extend to the location of the first air guide tube 29 and the second air guide tube 30, providing protection for them. (Reference) Figure 16-19 As an example of this embodiment, the outer casing assembly 5 includes a first housing 23, which is spaced apart on the outer periphery of the transducer housing 2a, thereby forming a fourth channel 24 between the first housing 23 and the transducer housing 2a. The fourth channel 24 communicates with the exhaust port 16b and has an exhaust port 24a facing the front end. In this way, the cold air flowing through the first cooling air passage 14, after exiting the transducer housing 2a through the exhaust port 16b, enters the fourth channel 24 and flows towards the exhaust port 24a under the restriction of the fourth channel 24, and is finally discharged through the exhaust port 24a. Since the exhaust port 24a is arranged facing the front end, the cold air discharged through the exhaust port 24a can blow towards the tool 43 to cool the tool 43.

[0125] The outer casing assembly 5 also includes a second casing 25, which is arranged on the outer periphery of the first casing 23, thereby forming a third channel 26 between the second casing 25 and the first casing 23. The third channel 26 is provided with an air jet 26a that communicates with the outside. The second air guide pipe 30 is connected to the nozzle 28 through the air jet 26a.

[0126] The second air intake channel 27a can be independent of the first air intake channel 14c, meaning it can be connected to different external cooling air sources as needed, thus ensuring that the first cooling air path 14 and the second cooling air path 27a are independent and do not interfere with each other. Alternatively, the second air intake channel 27a and the first air intake channel 14c can be connected to the same cooling air source, with independent air supply to each channel via valves. In the aforementioned cases, the second air intake channel 27a will always introduce cool air independently of the first air intake channel 14c, allowing the cool air to flow along the third channel 26 to the jet nozzle 26a. The jet nozzle 26a can be connected to a nozzle 28 positioned towards the tool 43, or the jet nozzle 26a itself can be positioned towards the tool 43, allowing the cool air introduced through the second air intake channel 27a to be directly blown onto the tool 43 for heat exchange.

[0127] The cutting tool 43 of this ultrasonic scalpel holder 100 can exchange heat with two separate cooling air streams. One stream flows through the first cooling air path 14 and the third cooling air path 16 to the exhaust port 24a, and the other stream flows through the second cooling air path 27 to the jet port 26a. Under the cooling effect of these two streams, the cutting tool 43 and the material being cut by the ultrasonic scalpel holder 100 can be effectively cooled, thus preventing the material from absorbing too much heat during the cutting process, which could lead to the melting of adhesive inside the material or the adhesion of chips to the cutting tool 43.

[0128] Guided by the first air guide pipe 29 and the second air guide pipe 30, the cold air entering the second cooling air passage 27 through the second air intake passage 27a flows along the axial direction of the tool body 1 and then along the circumference of the amplitude transformer 42. In this way, the cold air ejected through the jet nozzle 26a can blow from the circumference of the amplitude transformer 42 onto the tool 43, thus fully cooling all parts of the tool 43. The second air guide pipe 30 is preferably arranged around the circumference of the amplitude transformer 42, so that the jet nozzles 26a distributed along the arrangement path of the second air guide pipe 30 can be arranged around the tool 43, so that the cold air can fully contact the tool 43.

[0129] Furthermore, the third channel 26 can be filled with insulation material to form an insulation layer (not shown in the figure) covering the first air guide pipe 29 and the second air guide pipe 30, ensuring that the cold air in the second cooling air passage 27 is maintained at a low temperature. Of course, the insulation material can also assist in the connection and cooperation between the first housing 23 and the second housing 25. For example, the rear end of the second housing 25 is fixedly connected to the airflow seat 5b, the first housing 23 is fixed inside the second housing 25 by the insulation material, and in order to fix the first air guide pipe 29, a bracket is provided inside the second housing 25 to fix the first air guide pipe 29 to the second housing 25.

[0130] It should be noted that the ultrasonic scalpel handle 100 with the first cooling air passage 14 and the second cooling air passage 27 is also applicable to ultrasonic scalpel handles 100 where the scalpel body 1 and the transducer housing 2a are integrally formed. In ultrasonic scalpel handles where the scalpel body 1 and the transducer housing 2a are integrally formed, the design of the first cooling air passage 14, the second cooling air passage 27, and the third cooling air passage 16 is the same as that of the ultrasonic scalpel handle 100, and will not be described separately here.

[0131] When the ultrasonic tool holder 100 is in operation, the spindle of the machine tool is connected to the rear side of the tool body 1, driving the tool body 1 to rotate. During the rotation of the tool body 1, the outer housing assembly 5 remains stationary relative to the tool body 1. However, because the tool body 1 can rotate relative to the outer housing assembly 5, after the tool body 1 disengages from the spindle, relative rotation occurs between the tool body 1 and the outer housing assembly 5. This causes the tool body 1 to deviate from its docking position with the spindle, resulting in the spindle being unable to align with the tool body 1 when the ultrasonic tool holder 100 is re-engaged, thus preventing tool changing on the machine tool. To address this issue, a limiting structure can be provided on the ultrasonic tool holder 100 to restrict the relative rotation between the tool body 1 and the outer housing assembly 5 when the tool body 1 is disengaged from the spindle.

[0132] refer to Figure 20-24 As an example of this embodiment, a receiving groove 31 is fixedly connected to the outer periphery of the blade body 1, the wireless receiving component 3 is arranged in the receiving groove 31, and a positioning groove 32 is provided on the outer periphery of the receiving groove 31.

[0133] The outer shell assembly 5 is provided with a first positioning component 33 and a second positioning component 34 that are movable relative to the outer shell assembly 5. The movement of the second positioning component 34 relative to the outer shell assembly 5 can drive the first positioning component 33 to move, causing the first positioning component 33 to disengage from the positioning groove 32, so that the receiving groove 31 and the outer shell assembly 5 can rotate relative to each other, that is, the blade body 1 and the outer shell assembly 5 can rotate relative to each other; and the first positioning component 33 can be driven to extend into the positioning groove 32, so that the receiving groove 31 and the outer shell assembly 5 are relatively stationary, that is, the blade body 1 and the outer shell assembly 5 are relatively stationary.

[0134] As an example of this embodiment, by setting a first positioning component 33 and a second positioning component 34, the second positioning component 34 can extend outside the outer shell assembly 5. When the ultrasonic scalpel handle 100 is connected to the spindle, the second positioning component 34 extending outside the outer shell assembly 5 can be squeezed, thereby driving the first positioning component 33 to move, causing the first positioning component 33 to disengage from the positioning groove 32, so that the receiving groove 31 and the outer shell assembly 5 can rotate relative to each other. Since the receiving groove 31 is fixedly connected to the blade body 1, the blade body 1 and the outer shell assembly 5 can rotate relative to each other at this time. When the ultrasonic scalpel handle 100 is detached from the spindle, the second positioning component 34 extending outside the outer shell assembly 5 can return to its original position, and with the help of other means, the first positioning component 33 can be driven to move in the opposite direction, so that the first positioning component 33 extends into the positioning groove 32, thereby making the receiving groove 31 and the outer shell assembly 5 relatively stationary. Since the receiving groove 31 is fixedly connected to the blade body 1, the blade body 1 is also relatively stationary with respect to the outer shell assembly 5 at this time.

[0135] Of course, the second positioning component 34 may not extend out of the outer shell component 5, but a unit that can abut against the second positioning component 34 is provided at the spindle end. When the ultrasonic scalpel handle 100 is installed on the spindle, the second positioning component 34 can also be squeezed.

[0136] It should be noted that in some ultrasonic scalpel holders 100, the ultrasonic scalpel holder 100 can be driven by a brush structure or other electrical connection structure. Therefore, in these ultrasonic scalpel holders 100, the positioning groove 32 can also be directly set on the outer periphery of the scalpel body 1, so that the first positioning component 33 and the second positioning component 34 directly cooperate with the scalpel body 1. The way in which the first positioning component 33 and the second positioning component 34 cooperate with the scalpel body 1 is the same as the way in which the first positioning component 33 and the second positioning component 34 cooperate with the receiving groove 31, and will not be described again here.

[0137] The first positioning component 33 can extend into and exit the positioning groove 32 in various ways. For example, the first positioning component 33 can move linearly along the radial direction of the cutter body 1 to enter and exit the positioning groove 32; or, the first positioning component 33 can also swing relative to the cutter body 1 to enter and exit the positioning groove 32. (Reference) Figure 20-24 As an example of this embodiment, the first positioning component 33 includes a swing block 33a, which is rotatably connected to the outer shell component 5. It moves closer to or further away from the positioning groove 32, so that the swing block 33a extends into the positioning groove 32 or moves out of the positioning groove 32.

[0138] It should be noted that the swing block 33a extends at least partially beyond the outer shell assembly 5. Since the swing block 33a is rotatably connected to the outer shell assembly 5, it rotates relative to the outer shell assembly 5 when entering or exiting the positioning groove 32. For example, if the swing block 33a rotates clockwise relative to the outer shell assembly 5, it will disengage from the positioning groove 32; conversely, if it rotates counterclockwise relative to the outer shell assembly 5, it will extend into the positioning groove. Compared to a linear movement arrangement, the rotatable arrangement of the swing block 33a reduces the distance between the second positioning assembly 34 and the handle body, making the limiting structure composed of the first positioning assembly 33 and the second positioning assembly 34 more suitable for small-sized handle structures or handles with relatively large handle bodies, such as those with a wireless receiver mounted on the handle body. It also saves space occupied by the limiting structure and improves the space utilization of the outer shell assembly 5.

[0139] To drive the oscillating block 33a to rotate relative to the outer casing assembly 5, the first positioning assembly 33 may be configured with a movable structure for actuating the oscillating block 33a, thereby causing the oscillating block 33a to rotate. (Reference) Figure 20-24 As an example of this embodiment, the first positioning component 33 further includes a reciprocating slider 33b. The slider 33b is configured to reciprocate toward the outer periphery of the blade body 1. The end of the swing block 33a away from the receiving groove 31 is rotatably connected to the slider 33b, i.e., the end away from the positioning groove 32 is rotatably connected to the slider 33b. The end of the slider 33b away from the blade body 1 abuts against the second positioning component 34, thereby driving the slider 33b closer to the blade body 1, which in turn drives the swing block 33a to rotate, causing the other end of the swing block 33a to disengage from the positioning groove 32. Of course, the rotation center between the slider 33b and the swing block 33a is offset from the rotation center between the swing block 33a and the outer casing component 5.

[0140] Through the interaction of slider 33b and swing block 33a, swing block 33a can rotate relative to the outer shell assembly 5, thereby enabling the first positioning assembly 33 to perform the function of limiting or releasing the limit. To drive slider 33b to move and ensure that the first positioning assembly 33 can perform its function, refer to... Figure 20-24 As an example of this embodiment, a first elastic member 37 is provided on the outer shell assembly 5. The first elastic member 37 is arranged on the side of the slider 33b near the blade body. One end of the first elastic member 37 abuts against the end of the slider 33b near the blade body 1, and the other end of the first elastic member 37 is fixedly disposed, so that the first elastic member 37 can apply a force to the slider 33b away from the blade body 1, so that the slider 33b has a tendency to move away from the blade body 1.

[0141] There are multiple ways to achieve the movement of the second positioning component 34 relative to the outer shell component 5, and using a positioning post 34a is one feasible solution. (Reference) Figure 20-24 The second positioning component 34 includes a positioning post 34a, which can reciprocate along the axial direction of the blade body 1, and the end of the slider 33b away from the blade body 1 can abut against the positioning post 34a to drive the swing block 33a out of the positioning groove 32.

[0142] Understandably, under the action of the first elastic element 37, the slider 33b is subjected to a force that moves it away from the tool body 1, causing the end of the slider 33b away from the tool body 1 to abut against the positioning post 34a. Of course, to limit the travel distance of the slider 33b, refer to... Figure 20-24 As an example of this embodiment, the second positioning component also includes a limiting block 34b. The front end of the positioning post 34a is connected to the limiting block 34b. The limiting block 34b is provided with a recessed clearance 34b1. The positioning post 34a can reciprocate along the axial direction of the cutter body 1, so that the clearance 34b1 can be moved to the position of the slider 33b, so that the slider 33b extends into the clearance 34b1, thereby causing the slider 33b to drive the swing block 33a to extend into the positioning groove 32.

[0143] The limiting block 34b and the positioning post 34a can be an integral structure or separate structures. Under the action of the limiting block 34b, the slider 33b driven by the first elastic element 37 will enter the clearance position 34b1 and be constrained by the limiting block 34b, thus preventing the slider 33b from completely coming out and causing the limiting structure to fail. As the second positioning component 34 moves forward along the axis of the cutter body 1, the second positioning component 34 will push the slider 33b back towards the cutter body 1, ensuring that the positioning post 34a can move to the horizontal position where the slider 33b is located, so that the swing block 33a is driven to come out of the positioning groove 32.

[0144] To facilitate the engagement of the limiting block 34b and the slider 33b, an inclined surface 34b10 inclined in the front-rear direction can be provided on the outer periphery of the limiting block 34b. The inclined surface 34b10 is arranged on the rear side of the clearance position 34b1, gradually converging towards the front side of the limiting block 34b and connecting into the clearance position 34b1. In this way, when the limiting block 34b moves towards the front end of the cutter body 1, the inclined surface 34b10 can gradually push the slider 33b towards the cutter body 1, preventing the slider 33b from getting stuck inside the clearance position 34b1. Moreover, the inclined surface 34b10 extends to the outer periphery of the positioning post 34a. When the second positioning component continues to move forward, the end of the slider 33b that contacts the second positioning component 34 can gradually move along the inclined surface 34b10 to the positioning post 34a, preventing the slider 33b from getting stuck during movement.

[0145] In addition, refer to Figure 20-24As an example of this embodiment, the end of the slider 33b facing the positioning post 34a is rotatably connected to a pulley 39, and the outer edge of the pulley 39 extends out of the slider 33b, so that the pulley 39 can roll and cooperate with the second positioning component 34, making the slider 33b move more smoothly. The second positioning component 34 can drive the slider 33b closer to the blade body 1 through the pulley 39.

[0146] To drive the second positioning component 34 to operate and ensure that the second positioning component 34 can perform its function, refer to Figure 20-24 As an example of this embodiment, the outer shell assembly 5 is further provided with a second elastic member 40. One end of the second elastic member 40 abuts against the front end of the second positioning assembly 34, and the other end of the second elastic member 40 is fixedly disposed so that the second positioning assembly 34, after being squeezed, tends to move towards the rear side of the tool body 1, thereby applying a force to the second positioning assembly 34 to move towards the rear side. As for the force that squeezes the second positioning assembly 34, it can be the force applied to the second positioning assembly by the spindle when the tool holder is installed with the spindle, as has been explained above.

[0147] Of course, in order to facilitate the rotation of the swing block 33a relative to the outer casing assembly 5, and to provide necessary protection for the first positioning assembly 33 and the second positioning assembly 34, a groove structure may be configured inside the outer casing assembly. (See reference) Figure 20-24 As an example of this embodiment, a first mounting groove 35 is provided inside the outer shell assembly 5. The first mounting groove 35 extends toward the blade body 1 from the outer periphery of the blade body 1, and the slider 33b can reciprocate within the first mounting groove 35.

[0148] It is understandable that the first mounting groove 35 is arranged on the outer periphery of the cutter body 1 and extends towards the cutter body 1, causing the first mounting groove 35 to be inclined at / perpendicular to the axial direction of the cutter body 1. Therefore, the slider 33b, which moves back and forth within the first mounting groove 35, will move back and forth towards and away from the cutter body 1 as it moves. Since the swing block 33a rotates relative to the outer shell assembly 5, there must be a rotation center between the swing block 33a and the outer shell assembly 5. This rotation center is usually a shaft structure.

[0149] The first elastic element 37 is disposed within the first mounting groove 35 and arranged on the side of the slider 33b near the blade body. It can apply a force to the slider 33b away from the blade body 1, causing the slider 33b to tend to move away from the blade body 1 along the first mounting groove 35. As the slider 33b reciprocates towards and away from the blade body 1, the end of the swing block 33a away from the slider 33b reciprocates into or out of the positioning groove 32 through the rotation center between the swing block 33a and the outer shell assembly 5. Since the rotation center between the slider 33b and the swing block 33a is offset from the rotation center between the swing block 33a and the outer shell assembly 5, and the first mounting groove 35 is inside the outer shell assembly 5 while the swing block 33a extends to the outside of the outer shell assembly 5, the slider 33b is located in front of the swing block 33a, and the rear end of the swing block 33a extends outside the outer shell assembly 5. At this time, as the slider 33b moves, it will push the swing block 33a, and the swing block 33a will then rotate relative to the outer shell assembly 5.

[0150] Based on the rotational movement of the swing block 33a, the outer shell assembly 5 needs to be equipped with corresponding space for the swing block 33a to rotate. Therefore, the outer shell assembly 5 is also provided with a second mounting groove 36. The second mounting groove 36 is arranged in the front-back direction, and the front end of the second mounting groove 36 is connected to the first mounting groove 35, and the rear end of the second mounting groove 36 is connected to the positioning groove 32. The swing block 33a is rotatably connected in the second mounting groove 36, and the rear end of the swing block 33a extends out of the second mounting groove 36. In addition, the outer shell assembly 5 is also provided with a third mounting groove 38. The third mounting groove 38 is arranged in the front-back direction, and the end of the first mounting groove 35 away from the blade body 1 is connected to the third mounting groove 38. Furthermore, the positioning pin 34a can reciprocate in the third mounting groove 38, and the positioning pin 34a can move to the position where the first mounting groove 35 and the third mounting groove 38 are connected, so as to restrict the slider 33b from disengaging from the first mounting groove 35, thereby causing the slider 33b to drive the swing block 33a out of the positioning groove 32.

[0151] The first elastic element 37 can be a spring. The positioning post 34a and the first elastic element 37 cooperate to provide a means for the slider 33b to reciprocate within the first mounting groove 35: the slider 33b presses against the first elastic element 37 within the first mounting groove 35, causing the first elastic element 37 to apply a force to the slider 33b away from the blade body 1, driving the slider 33b away from the blade body 1. After the connection between the positioning post 34a and the limiting block 34b moves to the position where the first mounting groove 35 and the third mounting groove 38 connect, during the continued driving of the second positioning assembly 34 towards the rear end of the blade body 1, the slider 33b will actuate the swing block 33a, causing the swing block 33a to rotate towards the positioning groove 32 and extend... The first positioning component 34 is driven to move towards the front end of the blade 1. When the positioning post 34a moves to the position where the first mounting groove 35 and the third mounting groove 38 are connected, the slider 33b is pushed into the first mounting groove 35, causing the first elastic element 37 to be squeezed. The positioning post 34a blocks the port of the first mounting groove 35, preventing the slider 33b from coming out of the first mounting groove 35. During this process, the slider 33b will move the swing block 33a away from the positioning groove 32 and come out of the positioning groove 32, so that the blade 1 can rotate relative to the outer shell assembly 5.

[0152] To drive the second positioning component 34 to move and ensure its function, a second elastic member 40 is disposed within the third mounting groove 38. The second elastic member 40 abuts against the front end of the second positioning component 34, causing the second positioning component 34 to tend to move along the rear side of the third mounting groove 38, thus applying a rearward force to the second positioning component 34. Of course, to prevent the second positioning component 34 from dislodging from the third mounting groove 38, the third mounting groove 38 can be configured as a countersunk hole structure or have a limiting structure within the channel; further details are omitted here.

[0153] It should be noted that the first positioning component 33 and the second positioning component 34 can also be set on the rear side of the outer shell component 5 without the need for a groove structure. For example, the first positioning component 33 and the second positioning component 34 can be outside the outer shell component 5, such as the slider 33b sliding on the rear end face of the outer shell component 5, and the swing block 33a being rotatably connected to the outer shell component 5 by means of a fixed rod.

[0154] It should be noted that the limiting structure composed of the first positioning component 33 and the second positioning component 34 can be applied to other knife handle structures, such as non-ultrasonic knife handles, ultrasonic knife handles with the knife body and transducer housing integrally connected, or ultrasonic knife handles without wireless transmission structures. In other knife handle structures, the positioning groove 32 is located on the outer periphery of the knife handle body, and the outer shell component 5 is rotatably sleeved on the outer periphery of the knife handle body. As for the structural composition of the first positioning component 33 and the second positioning component 34, it is the same as the structural composition used in this ultrasonic knife handle 100, and will not be described again here.

[0155] Based on the aforementioned ultrasonic tool holder 100, this embodiment also provides an ultrasonic processing device, including the aforementioned ultrasonic tool holder 100.

[0156] Based on the aforementioned ultrasonic processing equipment, this embodiment also provides a machine tool, including a machine tool body, a spindle mounted on the machine tool body, and the aforementioned ultrasonic processing equipment.

[0157] In summary, the ultrasonic scalpel handle 100 provided in this embodiment forms a mounting portion 4 at the connection position between the scalpel body 1 and the transducer housing 2a through a detachably connected scalpel body 1. The mounting portion 4 is recessed within the scalpel body 1, making the outer diameter of the mounting portion 4 smaller than the outer diameter of the scalpel body 1. In this way, the bearing 8 can be fitted onto the mounting portion 4, which can effectively reduce the size of the bearing 8. When the ultrasonic scalpel handle 100 rotates at high speed, the linear velocity of the inner ring of the bearing 8 can be effectively reduced, thereby reducing the heat generated by the bearing 8 and improving the service life of the bearing 8. This solves the problem of the existing ultrasonic scalpel handle 100 requiring frequent maintenance and replacement of the bearing 8.

[0158] Furthermore, in this embodiment, the ultrasonic scalpel handle 100 provides an electrical connection path within the scalpel body 1 and the mounting portion 4, enabling the wireless receiving component 3 to be mounted on the scalpel body 1 and connected to the transducer 2b. Moreover, the built-in electrical connection path ensures that the wire between the wireless receiving component 3 and the transducer 2b is not affected by the high-speed rotation of the ultrasonic scalpel handle 100, thus preventing interference between the wire and the outer casing component 5 and the bearing 8, which would affect the normal operation of the ultrasonic scalpel handle 100.

[0159] Furthermore, the cooling channel 13 and the first cooling air path 14 provided in the ultrasonic scalpel handle 100 of this embodiment are used to cool the transducer 2b by means of the first cooling air path 14, thereby reducing the heat generation of the transducer 2b and preventing the transducer 2b from overheating and causing the ultrasonic scalpel handle 100 to malfunction. Moreover, the cooling channel 13 is connected to the first cooling air path 14 at the rear end of the transducer housing 2a, so that the airflow passes through the transducer 2b along the axial direction of the scalpel body 1, thereby ensuring the flow rate of the cold air in the transducer housing 2a and avoiding the loss of flow rate caused by the cold air turning in the transducer housing 2a.

[0160] Furthermore, in this embodiment, the ultrasonic scalpel handle 100 is provided with independent first air intake channels 14c and second air intake channels 27a, so that the first cooling air path 14 and the second cooling air path 27 are independent of each other and do not interfere with each other. In this way, the ultrasonic scalpel handle 100 can independently supply air to the transducer 2b and the cutter 43 according to the heat generation of the transducer 2b and the cutter 43, respectively, to achieve independent cooling of the transducer 2b and the cutter 43.

[0161] Furthermore, the ultrasonic scalpel handle 100 of this embodiment, by setting a limiting structure, allows the ultrasonic scalpel handle 100 to be in a state of disengagement from the spindle. The first positioning component 33 and the second positioning component 34 cooperate with each other, so that the first positioning component 33 extends into the positioning groove 32, thereby fixing the relative position of the scalpel body 1 and the outer shell assembly 5, thus keeping the scalpel body 1 and the outer shell assembly 5 relatively stationary. When the ultrasonic scalpel handle 100 is connected to the spindle, the limiting structure can unlock from the positioning groove 32, allowing the scalpel body 1 and the transducer housing 2a to rotate relative to the outer shell assembly 5 without affecting the normal operation of the ultrasonic scalpel handle 100.

[0162] This embodiment also provides an ultrasonic processing device and machine tool, which uses the aforementioned ultrasonic tool holder 100 and has the aforementioned beneficial effects of the ultrasonic tool holder 100.

[0163] The first positioning component 33 and the second positioning component 34 of this embodiment are also applicable to non-ultrasonic tool holders and integrated tool holders, and have the beneficial effects of the aforementioned first positioning component 33 and second positioning component 34. Furthermore, this embodiment also provides a machine tool that uses this type of tool holder and has the beneficial effects of this type of tool holder.

[0164] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
