Description

An ultrasonic tool holder, ultrasonic processing equipment and machine tool Technical Field

[0001] This invention 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] Existing ultrasonic scalpel holders generally include a holder body, a transducer assembly, and an electrical power transmission structure. The electrical power transmission structure includes a conductive ring and an insulating structure that fixes the conductive ring. Since the conductive ring is typically directly fitted onto the outer periphery of the transducer assembly housing or the holder body, and radially connected to the ultrasonic vibrating element via the inner cavity of the transducer assembly to achieve electrical connection between the electrical power transmission mechanism and the ultrasonic vibrating element, the radial dimension of the conductive ring is often larger than the radial dimension of the inner cavity of the transducer assembly. This results in a high linear velocity on the outer periphery of the conductive ring when the holder body drives the transducer assembly and the electrical power transmission structure to rotate. The brushes directly connected to the conductive ring generate a large amount of heat, leading to severe overheating of the conductive ring and affecting its service life.

[0004] To avoid overheating of the conductive ring, existing ultrasonic tool holders generally use a low-speed configuration. However, this will affect the processing efficiency and performance of the ultrasonic tool holder. Summary of the Invention

[0005] This invention provides an ultrasonic tool holder, ultrasonic processing equipment, and machine tool.

[0037] Compared with the prior art, the ultrasonic tool holder, ultrasonic processing equipment, and machine tool implemented in this invention have the following advantages:

[0038] The ultrasonic scalpel handle of the present invention forms a mounting portion through a detachably connected scalpel body and transducer housing, allowing the conductive component to be fitted onto the mounting portion. This enables the conductive ring to adopt an integral structure. Furthermore, the outer diameter of the conductive ring is less than or equal to the outer diameter of the transducer housing adjacent to the mounting portion. By reducing the outer diameter of the conductive ring, the linear velocity of the conductive ring is reduced, thus reducing the heat generated by the conductive ring and improving the service life of the conductive component. This solves the problem of high conductive ring linear velocity and severe heat generation in existing ultrasonic scalpel handles, making it difficult to apply ultrasonic scalpel handles to high-speed machining. Moreover, since the conductive component is fitted onto the mounting portion formed by the connection between the scalpel body and the transducer housing, changes in the size of the conductive ring will not affect the internal cavity dimensions of the transducer housing, i.e., will not affect the transducer specifications. Therefore, even if the size of the conductive ring is adjusted according to functional requirements, the power of the transducer can be guaranteed to remain unaffected, and the normal operation of the ultrasonic scalpel handle will not be affected.

[0039] The present invention also provides an ultrasonic processing device and machine tool, which uses the aforementioned ultrasonic tool holder and has the aforementioned beneficial effects of the ultrasonic tool holder. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0072] Example

[0073] Referring to Figures 1-26, an embodiment of the present invention provides an ultrasonic scalpel holder 100, which includes a scalpel body 1, a transducer assembly, and a conductive assembly 3. The end of the ultrasonic scalpel holder 100 connected to the machining tool is considered the front side. The transducer assembly includes a transducer housing 2a and a transducer 2b. An inner cavity 20a is provided within the transducer housing 2a to accommodate the transducer 2b. The scalpel body 1 is detachably connected to the transducer housing 2a and forms a mounting portion 4. The connection between the scalpel body 1 and the transducer housing 2a constitutes the scalpel holder body.

[0074] It is understood that transducer 2b is generally used to convert electromagnetic energy into mechanical energy. In some embodiments, transducer 2b includes a piezoelectric vibrator. In some embodiments, the amplitude transformer 33 mounted at its front end is a component for amplifying the mechanical amplitude. In some embodiments, the piezoelectric vibrator is mounted in the inner cavity 20a, and the amplitude transformer 33 extends from the inner cavity 20a to the front side of the transducer assembly and connects to the machining tool. The specific configuration of transducer 2b can be determined according to the application scenario of ultrasonic tool holder 100 and the target to be processed, and will not be elaborated here.

[0075] The performance of the transducer assembly is closely related to the size of the transducer 2b, such as the size of the piezoelectric vibrator. The piezoelectric vibrator is installed inside the inner cavity 20a of the transducer housing 2a. Therefore, the size of the inner cavity 20a inside the transducer housing 2a generally reflects the performance of the transducer assembly. Changing the size of the inner cavity 20a will affect the performance of the transducer assembly, such as the output power.

[0076] The conductive component 3 is fitted onto the mounting portion 4. As an example of the embodiment, the conductive component 3 includes a conductive ring 3a electrically connected to a transducer 2b in the transducer housing 2a, and the outer diameter of the conductive ring 3a is less than or equal to the outer diameter of the transducer housing 2a adjacent to the mounting portion 4. In this way, the conductive ring 3a does not need to be located on the outer periphery of the transducer housing 2a, and the outer diameter of the conductive ring 3a can be effectively reduced. When other conductive elements that can be matched with the conductive ring 3a slide relative to each other on the outer periphery of the conductive ring 3a, at the same rotational speed, compared to a conductive ring directly mounted on the outer periphery of the transducer housing, the linear velocity of the conductive ring 3a fitted onto the mounting portion 4 in this application can be significantly reduced. This allows the conductive ring 3a to operate at a relatively higher rotational speed, reduces frictional heat generation of the conductive ring 3a, and improves the service life of the conductive component 3. For example, for the HSK63 ultrasonic scalpel holder, its rotational speed can reach 3000-4000 r / min, and the service life of the conductive component 3 is well maintained.

[0077] Furthermore, the conductive component 3 is mounted on the mounting part 4 formed by the detachable connection between the blade body 1 and the transducer housing 2a. By disassembling the blade body 1 and the transducer housing 2a, a small-sized integrated conductive ring can be directly mounted on the mounting part 4, without the need for a split conductive ring structure. This avoids the problems of gaps between the two halves of the split conductive ring, resulting in high magnetic resistance, requiring the coating of the cross-section with materials with good conductivity such as silver to enhance conductivity, and also requiring ensuring the roughness of the cross-section, which imposes many limitations on its use and results in poor electrical transmission performance. Moreover, by making the blade body 1 and the transducer housing 2a detachable, the conductive component 3 can be replaced with a new one when its performance deteriorates, thereby further extending the service life of the ultrasonic scalpel handle 100.

[0078] It should be noted that, in order to reduce the linear velocity of the conductive ring 3a without affecting the transducer performance, in some embodiments, the mounting portion 4 formed by the connection between the blade body 1 and the transducer housing 2a is located at a different position along the axial direction of the ultrasonic scalpel handle 100 from the inner cavity 20a. In this way, when the conductive ring 3a is adjusted according to functional requirements, it will not affect the dimensions of the transducer 2b located within the inner cavity 20a, ensuring that the power of the transducer 2b meets the functional requirements of the ultrasonic scalpel handle 100.

[0079] It is understandable that the detachable connection between the blade body 1 and the transducer housing 2a can be achieved in various ways, and therefore, the mounting part 4 can be formed in various ways. The mounting part 4 only needs to ensure that the blade body 1 and the transducer housing 2a can be detachably connected; the point where the blade body 1 and the transducer housing 2a connect is the mounting part 4. For example, in some embodiments, the mounting part 4 can be formed by detachably connecting a portion of the blade body 1 integral structure and a portion of the transducer housing 2a integral structure. In this case, the mounting part 4 is both a part of the blade body 1 and a part of the transducer housing 2a. Alternatively, in some embodiments, the mounting part 4 can also be formed by connecting a structure separately connected to the blade body 1 and a structure separately connected to the transducer housing 2a; or it can be formed by a single structure detachably connected to both the blade body 1 and the transducer housing 2a. In this case, the mounting part 4 is a connection structure independent of the blade body 1 and the transducer housing 2a. Of course, in some embodiments, the mounting part 4 may also be part of the integral structure of the blade body 1 or part of the integral structure of the transducer housing 2a. By connecting part of the integral structure of the blade body 1 to the transducer housing 2a, or connecting part of the integral structure of the transducer housing 2a to the blade body 1, the blade body 1 and the transducer housing 2a are detachably connected to each other.

[0080] Understandably, since the conductive ring 3a is fitted onto the mounting portion 4, in order to ensure that the outer diameter of the conductive ring 3a is less than or equal to the outer diameter of the transducer housing 2a adjacent to the mounting portion, the outer diameter of the mounting portion 4 itself is generally smaller than the outer diameter of the transducer housing 2a. Alternatively, the outer diameter of a portion of the mounting portion 4 can be made smaller than the outer diameter of the transducer housing 2a by making the outer diameter of the connection end face between the blade 1 and the transducer housing 2a smaller than the outer diameter of the transducer housing 2a, thus making the outer diameter of the conductive ring 3a installed in that region smaller than the outer diameter of the transducer housing 2a.

[0081] In some embodiments, the mounting part 4 may be provided with a mounting space, such as an annular groove; in other embodiments, it may also form an annular groove with the adjacent transducer housing 2a and blade 1 to allow the conductive component 3 to be fitted and installed, and to ensure that the outer diameter of the conductive ring 3a of the conductive component 3 is less than or equal to the outer diameter of the transducer housing 2a adjacent to the mounting part 4.

[0082] Considering that the blade body 1 is often connected and driven by the spindle, in some embodiments, the blade body 1 in the ultrasonic scalpel holder 100 is often equipped with a flange structure 10b for abutting against the end of the spindle. The flange structure 10b is generally adapted to the spindle and can also reflect the operating performance of the blade body 1. Therefore, when the outer diameter of the conductive ring 3a is less than or equal to the outer diameter of the transducer housing 2a adjacent to the mounting part, the outer diameter of the conductive ring 3a can also be less than or equal to the outer diameter of the flange structure 10b of the blade body 1.

[0083] The ultrasonic scalpel handle 100 of this application will be further described below, taking the connection between the integral structure of the scalpel body 1 and the integral structure of the transducer housing 2a to form the mounting part 4 as an example.

[0084] As an example of the embodiment, the transducer housing 2a includes a housing portion 21a and a second protrusion 22a arranged sequentially along its own axial direction. The housing portion 21a is located in front of the second protrusion 22a, and an inner cavity 20a is provided inside the housing portion 21a to accommodate the transducer 2b.

[0085] In some embodiments, the transducer housing 2a has a axial structure, wherein the outer diameter of the second protrusion 22a is smaller than the outer diameter of the housing portion 21a (in some embodiments, the outer diameter of the second protrusion 22a is smaller than the outer diameter of the housing portion 21a adjacent to the mounting portion 4), making the second protrusion 22a a structure that protrudes from the rear side of the housing portion 21a. In this way, the inner cavity 20a is always disposed within the housing portion 21a, and changes in the dimensions of the second protrusion 22a will not affect the dimensions of the inner cavity 20a, thus ensuring the performance of the transducer 2b. Of course, in other examples, the housing portion 21a and the second protrusion 22a of the transducer housing 2a can also be distinguished according to other standards, such as using the boundary of the inner cavity 20a as the dividing line between the housing portion 21a and the second protrusion 22a. In this case, the inner cavity 20a is still disposed within the housing portion 21a, and changes in the dimensions of the second protrusion 22a will still not affect the dimensions of the inner cavity 20a.

[0086] In some embodiments, the blade body 1 is coaxially disposed with the transducer housing 2a, and the blade body 1 has a first protrusion 1a and a body portion 1b arranged sequentially along its own axial direction. 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 body portion 1b (in some embodiments, the outer diameter of the first protrusion 1a is smaller than the outer diameter of the body portion 1b adjacent to the mounting portion 4). The first protrusion 1a and the second protrusion 22a are detachably connected, thereby making the blade body 1 detachably connected with the transducer housing 2a, and the mounting portion 4 is formed at the connection between the first protrusion 1a and the second protrusion 22a.

[0087] In some embodiments, the cutter body 1 is a shaft structure, with the first protrusion 1a of the cutter body 1 connected to the second protrusion 22a, and the main body 1b of the cutter body 1 used to connect to the spindle. Therefore, when the ultrasonic cutter 100 is used to process materials, the main body 1b of the cutter body 1 is connected to the spindle, so that the cutter body 1 can be driven by the spindle to rotate, thereby causing the transducer assembly and the processing tool connected to the first protrusion 1a of the cutter body 1 to rotate synchronously and perform processing actions.

[0088] It is understood that the first protrusion 1a and body 1b of the blade body 1, and the shell 21a and second protrusion 22a of the transducer housing 2a, are only used to illustrate the detachable connection between the blade body 1 and the transducer housing 2a. They do not imply that the blade body 1 and the transducer housing 2a need to have clearly defined demarcation structures to form a two-section structure. In specific applications, the structure of the blade body 1 and the transducer housing 2a can adopt an integrated connection structure or a segmented structure depending on the application scenario; they do not necessarily have a two-section structural design.

[0089] Considering the mechanical strength of the ultrasonic scalpel holder 100 and the conduction efficiency of the conductive ring 3a, in some embodiments, when the conductive ring 3a is fitted onto the mounting portion 4, the outer diameter of the conductive ring 3a is greater than 50% of the outer diameter of the transducer housing 2a adjacent to the mounting portion 4. The specifications of the conductive ring 3a affect its conduction efficiency. If the size of the conductive ring 3a is too small, it will mainly lead to a decrease in the strength of the ultrasonic scalpel holder 100, and the efficiency of the electrical signal received by the transducer 2b will also be affected, causing the transducer 2b to be unable to work at the set power, or it may be necessary to extend the axial length of the conductive ring 3a to increase the contact area with the brush and increase the transmission efficiency, but this will result in a larger axial dimension of the ultrasonic scalpel holder 100, leading to a significant loss of ultrasonic performance. By limiting the lower limit of the outer diameter of the conductive ring 3a, the mechanical strength of the ultrasonic scalpel holder 100 is ensured without affecting energy transmission.

[0090] It should be noted that the transducer housing 2a adjacent to the mounting part 4 or the blade 1 adjacent to the mounting part 4 refers to the part of the transducer housing 2a located beside the mounting part 4 or the part of the blade 1 located beside the mounting part 4 in the axial direction of the blade 1.

[0091] Referring to Figures 1-13, as an example of the described embodiment, the ultrasonic scalpel handle 100 further includes a fixing component 5. The fixing component 5 is rotatably sleeved on the outer periphery of the transducer housing 2a and rotatably connected to the transducer housing 2a, allowing both parts of the transducer housing 2a and the scalpel body 1 to rotate relative to the fixing component 5. Furthermore, the fixing component 5 has a cavity 5a for accommodating the conductive component 3, allowing the conductive ring 3a to be enclosed by the fixing component 5, providing a certain degree of protection. Alternatively, the fixing component 5 can also be rotatably sleeved on the outer periphery of the scalpel body 1 and rotatably connected to the scalpel body 1 to form the cavity 5a; similarly, both parts of the transducer housing 2a and the scalpel body 1 can rotate relative to the fixing component 5.

[0092] In some embodiments, a first bearing 8 may be provided on the outer periphery of the transducer housing 2a, with the inner ring of the first bearing 8 fitted onto the housing portion 21a of the transducer housing 2a, and the fixing component 5 connected to the outer ring of the first bearing 8. This allows the transducer housing 2a to rotate relative to the fixing component 5, thereby allowing the blade 1 connected to the second protrusion 22a to also rotate relative to the fixing component 5. Of course, in other examples, the bearing may also be provided between the blade 1 and the fixing component 5; or, bearings may be provided both between the blade 1 and the fixing component 5, and between the transducer housing 2a and the fixing component 5. This allows the blade 1 and the transducer housing 2a to rotate relative to the fixing component 5, achieving a rotatable connection with the fixing component 5.

[0093] In some embodiments, a brush holder 6 is provided within the cavity 5a, and a brush (not shown in the figure) is mounted on the brush holder 6 that slides with the conductive component 3. In some embodiments, an external power supply extends into the cavity 5a through a lead wire passing through the holder 5 and is connected to the brush holder 6. The brush on the brush holder 6 is slidably connected to the conductive ring 3a and contacts the conductive ring 3a of the conductive component 3 to form a circuit, and the conductive ring 3a is electrically connected to the transducer 2b, so that the transducer 2b is connected to the external power supply, completing the wired transmission of the ultrasonic signal.

[0094] Referring to Figures 1-13, in some embodiments, the fixing component 5 includes an upper cover 5b, an outer shell 5c, and a lower cover 5d. The outer shell 5c is disposed between the upper cover 5b and the lower cover 5d, with its front side connected to the lower cover 5d and its rear side connected to the upper cover 5b, forming a cavity 5a. In some embodiments, the upper cover 5b is located beside the mounting part 4 and is disposed on the outer periphery of the blade body 1. The lower cover 5d is also located beside the mounting part 4 and is fitted onto the outer periphery of the transducer housing 2a. This allows the cavity 5a formed by the sequential splicing of the lower cover 5d, the outer shell 5c, and the upper cover 5b to accommodate the mounting part 4, allowing the conductive component 3 to be housed within the cavity 5a.

[0095] In some embodiments, the lower cover 5d is fitted onto the outer ring of the first bearing 8 and extends to the front side of the first bearing 8, and the inner ring of the first bearing 8 is connected to the transducer housing 2a, so that the transducer housing 2a can rotate relative to the fixed assembly 5.

[0096] In some embodiments, the fixing assembly 5 further includes a bearing pressing part 9 located in the cavity 5a, the bearing pressing part 9 pressing against the rear side of the first bearing 8, and the bearing pressing part 9 lockingly connected to the lower cover 5d, so that the lower cover 5d is securely installed on the outer ring of the first bearing 8.

[0097] It should be noted that, generally speaking, in some embodiments, the lower cover 5d and the housing portion 21a do not directly contact each other; in these embodiments, the significance of the lower cover 5d and the bearing pressing portion 9 is that the first bearing 8 is limited by the flange on the outer periphery of the transducer housing 2a and the bearing cap 7 on the top of the first bearing 8. The bearing cap 7 is installed on the transducer housing 2a and abuts against the inner ring of the first bearing 8. The bearing pressing portion 9 is installed on the outer ring of the first bearing 8 and locked with the lower cover 5d, thereby fixing the lower cover 5d and the outer ring of the first bearing 8.

[0098] To enable the conductive component 3 to be fixed axially in the blade body 1, in some embodiments, the mounting portion 4 can form a groove structure with the adjacent blade body and transducer housing for mounting the conductive component 3. Referring to Figures 1-13, as an example of the embodiment, the outer diameter of the second protrusion 22a is smaller than the outer diameter of the housing portion 21a (in some embodiments, the outer diameter of the second protrusion 22a is smaller than the outer diameter of the housing portion 21a adjacent to the mounting portion 4), and the outer diameter of the first protrusion 1a is smaller than the outer diameter of the body portion 1b. Thus, after the second protrusion 22a and the first protrusion 1a are connected to form the mounting portion 4, the outer peripheral surface of the mounting portion 4, the front end surface of the body portion 1b, and the rear end surface of the housing portion 21a together form an annular groove 10. The annular groove 10 is arranged circumferentially along the blade body 1 and has an opening facing outward of the blade body 1. The annular groove 10 is recessed into the outer peripheral side of the body portion 1b and the housing portion 21a adjacent to the annular groove 10. The conductive ring 3a is arranged in the annular groove 10 and electrically connected to the transducer 2b. In this way, the position of the conductive ring 3a in the axial direction of the cutter body 1 is defined by the annular groove 10.

[0099] It is understandable that, since the annular groove 10 is arranged in the mounting part 4 and its adjacent area, and the conductive ring 3a is installed in the annular groove 10, in some embodiments, the first bearing 8 will avoid interference between the first bearing 8 and the conductive ring 3a. As an example of the above embodiments, the first bearing 8 is located on the front side of the annular groove 10 in the axial direction of the cutter body 1. In this way, the upper cover 5b and the bearing pressing part 9 will be close to the annular groove 10 in the axial direction of the cutter body 1. Therefore, the brush holder 6 can be installed on the upper cover 5b or the bearing pressing part 9, so that the brush on the brush holder 6 can be slidably connected with the conductive ring 3a to achieve conductivity.

[0100] In some embodiments, the mounting portion 4 may also have an annular groove 10; for example, the annular groove 10 may be formed on the outer periphery of the first protrusion 1a or the second protrusion 22a; alternatively, the outer periphery of the first protrusion 1a or the second protrusion 22a may have a protrusion extending radially outward along the blade body 1, and the annular groove 10 may be formed by two protrusions extending side by side. In this way, the annular groove 10 can be formed on the mounting portion 4, allowing the conductive component 3 to be mounted within the annular groove 10 and fitted onto the mounting portion 4. Further details are not provided in the accompanying drawings.

[0101] In some embodiments, the fixing component 5 may further include a receiving base 5e, which is disposed on one side of the housing 5c ​​and is used to install the power-consuming side contact 26 (i.e., the power-consuming side connection end) that is electrically connected to the brush, so that the power-consuming side contact 26 can rotate relative to the blade body 1. Furthermore, the power-consuming side contact 26 is used to electrically connect to an external power source, so that the external power source can transmit electrical signals to the conductive component 3 through the power-consuming side contact 26.

[0102] When the ultrasonic scalpel handle 100 of the described embodiment 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. Referring to Figures 6-10, as an example of the described embodiment, the first protrusion 1a of the scalpel body 1 extends forward along the axial direction of the scalpel body 1, and a first mounting hole 11a is provided inside the scalpel body 1, which passes through the first protrusion 1a and the body portion 1b along the axial direction of the scalpel body 1; and,

[0103] The second protrusion 22a of the transducer housing 2a extends rearward along the axial direction of the cutter body 1, and the second protrusion 22a of the transducer housing 2a and the housing part 21a are jointly provided with a stepped hole 23a that runs through the axial direction of the cutter body 1. The stepped hole serves as a second mounting hole. The stepped hole 23a includes a large-diameter section 230aa and a small-diameter section 231a that are interconnected. The large-diameter section 230aa is partially located in the second protrusion 22a and partially located in the housing part 21a. The small-diameter section 231a is located in the housing part 21a and communicates with the inner cavity 20a.

[0104] In some embodiments, the first protrusion 1a is installed in the large-diameter section 230a of the stepped hole 23a, so that the second protrusion 22a wraps around the outer periphery of the first protrusion 1a, and forms the connection between the second protrusion 22a and the first protrusion 1a, i.e., the mounting part 4; and a locking member 30 is provided in the first mounting hole 11a, the locking member 30 penetrates the first protrusion 1a along the axial direction of the blade body 1, and extends into the small-diameter section 231a of the stepped hole 23a, and is fastened to the second protrusion 22a, so as to realize the detachable connection between the first protrusion 1a and the second protrusion 22a.

[0105] In some embodiments, the outer peripheral surface of the first protrusion 1a can be set as a conical surface, and correspondingly, the inner peripheral surface of the large diameter section 230aa of the stepped hole 23a is also set as a conical surface; in this way, when the locking member 30 locks the first protrusion 1a and the second protrusion 22a, the outer peripheral surface of the first protrusion 1a can be tightly fitted with the inner peripheral surface of the large diameter section 230aa of the stepped hole 23a, so that the first protrusion 1a and the second protrusion 22a are tightly connected.

[0106] In some embodiments, the outer diameter of the first protrusion 1a in the radial direction of the blade body 1 is smaller than the outer diameter of the body portion 1b of the adjacent mounting portion in the radial direction of the blade body 1, and the outer diameter of the second protrusion 22a in the radial direction of the blade body 1 is smaller than the outer diameter of the housing portion 21a of the adjacent mounting portion in the radial direction of the blade body 1. Therefore, after the first protrusion 1a is inserted into the second protrusion 22a, an annular groove 10 is formed between the blade body 1 and the transducer housing 2a, recessed on the outer peripheral side of the housing portion 21a and the outer peripheral side of the body portion 1b.

[0107] The connection relationship between the first protrusion 1a and the second protrusion 22a is not unique. As long as the two are connected and fixed in the axial direction of the blade body 1, the blade body 1 and the transducer housing 2a can be locked and fixed in the axial direction of the blade body 1.

[0108] For example, in other examples, referring to Figures 11-12, the first protrusion 1a of the blade body 1 extends forward along the axial direction of the blade body 1, and a first mounting hole 11a is provided inside the blade body 1, which passes through the first protrusion 1a and the body portion 1b along the axial direction of the blade body 1. Furthermore, the inner wall of the first mounting hole 11a protrudes towards the interior (e.g., the inner wall) of the first mounting hole 11a to form a limiting ring 110a; the second protrusion 22a of the transducer housing 2a extends rearward along the axial direction of the blade body 1, and a second mounting hole 24a, which passes through the axial direction of the blade body 1, is provided in both the second protrusion 22a and the housing portion 21a of the transducer housing 2a.

[0109] In some embodiments, the second protrusion 22a is installed within the first mounting hole 11a and located in front of the limiting ring 110a, thereby limiting the position of the second protrusion 22a along the axial direction of the cutter body 1 by the limiting ring 110a. In some embodiments, the second protrusion 22a is installed within the first mounting hole 11a such that the first protrusion 1a wraps around the outer periphery of the second protrusion 22a, forming the connection between the second protrusion 22a and the first protrusion 1a, i.e., the mounting portion 4.

[0110] In some embodiments, a locking member 30 is provided in the first mounting hole 11a. The locking member 30 passes through the limiting ring 110a along the axial direction of the blade body 1, extends into the second mounting hole 24a, and is fastened to the second protrusion 22a of the transducer housing 2a, thereby realizing a detachable connection between the first protrusion 1a and the second protrusion 22a. In some embodiments, the connection and cooperation between the first protrusion 1a and the second protrusion 22a, and the connection and cooperation between the locking member 30 and the transducer housing 2a, are based on the same principle as the structure shown in Figures 6-10. Since the transducer 2b is installed in the cavity 5a of the housing 21a, if the locking member 30 is located in the second mounting hole 24a on the side of the transducer housing 2a, when it is necessary to disassemble the blade body 1 from the transducer housing 2a, the transducer 2b must be removed first, and then the locking member 30 must be loosened from the second mounting hole 24a to disassemble the blade body 1 from the transducer housing 2a. However, if the locking member 30 is installed in the first mounting hole 11a on the side of the blade body 1, the locking member 30 can be loosened directly when the ultrasonic scalpel handle 100 is removed from the spindle to disassemble the blade body 1 from the transducer housing 2a. Therefore, the locking member 30 can also be installed in the second mounting hole 24a, but the disassembly is more complicated than when it is installed in the first mounting hole 11a.

[0111] For ease of installation, referring to Figures 6-10, in some embodiments, the first mounting hole 11a may be a countersunk hole, and a collar 31 is also installed in the first mounting hole 11a. The collar 31 is used to limit the axial displacement of the locking member 30. After the locking member 30 connects and fixes the first protrusion 1a and the second protrusion 22a, the collar 31 limits the axial displacement of the locking member 30 in the blade body 1. When it is necessary to disassemble the blade body 1 from the transducer housing 2a, the locking member 30 is loosened. Due to the presence of the collar 31, the locking member 30 will not exit the first mounting hole 11a. If the locking member 30 is loosened further, the blade body 1 is pushed out of the large-diameter hole in the transducer housing 2a, thereby separating the blade body 1 from the transducer housing 2a.

[0112] Referring to Figures 1-14, as an example of the described embodiment, the rear end face of the second protrusion 22a is provided with two first limiting grooves 220a, which are evenly arranged circumferentially along the second protrusion 22a. Correspondingly, the front end face of the body portion 1b is provided with a second limiting groove 11b. Each second limiting groove 11b is equipped with a locking block 32, and each locking block 32 extends into the corresponding first limiting groove 220a along the axial direction of the blade body 1, so that the blade body 1 can better transmit torque to the transducer housing 2a. Of course, the number of first limiting grooves 220a and second limiting grooves 11b can both be one, or it can be other numbers, for example, the number can be any integer greater than 1 according to actual needs.

[0113] Referring to Figures 1-14, as an example of the described embodiment, the conductive component 3 further includes a conductive mounting portion 3b and a voltage-conducting cover portion 3c. The conductive mounting portion 3b has a mounting groove 30b for accommodating the conductive ring 3a. The opening of the mounting groove 30b faces outward from the blade body 1, and the front side of the conductive mounting portion 3b abuts against the sidewall of the annular groove 10. The voltage-conducting cover portion 3c is pressed against the rear side of the conductive mounting portion 3b and is connected and fixed to the bottom of the annular groove 10. In some embodiments, since the second protrusion 22a sleeves the first protrusion 1a to form the mounting portion 4, the voltage-conducting cover portion 3c is connected and fixed to the second protrusion 22a.

[0114] In some embodiments, the conductive mounting portion 3b is made of insulating material, allowing the conductive ring 3a to be accommodated by the conductive mounting portion 3b. In some embodiments, in the axial direction of the blade body 1, the front side of the conductive mounting portion 3b abuts against the annular groove 10 against the side wall of the transducer housing 2a, i.e., the rear end face of the housing portion 21a, and the voltage-conducting cover portion 3c is pressed against the rear side of the conductive mounting portion 3b, thereby fixing the conductive assembly 3 in the axial position of the blade body 1.

[0115] In some embodiments, a plurality of mounting slots 30b may be provided within the conductive mounting portion 3b. These mounting slots 30b are arranged sequentially along the axial direction of the blade body 1, and each mounting slot 30b surrounds the connection between the second protrusion 22a and the first protrusion 1a, and has a notch facing outwards from the blade body 1. Correspondingly, the number of conductive rings 3a may also be multiple. In some embodiments, multiple conductive rings 3a are installed in a one-to-one correspondence with multiple mounting slots 30b. The number of conductive rings 3a and mounting slots 30b can be adjusted according to the electrical transmission requirements, so that the conductive rings 3a can meet the power requirements of the transducer 2b. In some embodiments, the number of conductive rings 3a may be two, including a rear conductor 30a and a front conductor 31a. The rear conductor 30a and the front conductor 31a are installed alternately within the mounting slots 30b, so that the positive and negative terminals of the transducer 2b can be connected through the rear conductor 30a and the front conductor 31a, respectively.

[0116] Considering that the conductive ring 3a is built into the annular groove 10 and recessed into the body portion 1b of the blade body 1 and the housing portion 21a of the transducer housing 2a, if the lead wire between the conductive ring 3a and the transducer 2b is arranged on the outside of the transducer housing 2a and enters the inner cavity 20a radially along the transducer housing 2a, the length of the lead wire will undoubtedly be too large, and it is easy for the lead wire to interfere with other structures, such as the fixing component 5, making it difficult to install the fixing component 5. Therefore, in some embodiments, the conductive ring 3a can achieve conductive communication with the transducer 2b in the axial direction of the blade body 1.

[0117] Referring to Figures 1-14, as an example of the described embodiment, the conductive component 3 further includes a conductive part 3f. This conductive part 3f can be inserted axially into the transducer housing 2a along the blade body 1. Furthermore, the conductive part 3f can be electrically connected to the conductive ring 3a and the transducer 2b to achieve an electrical connection between the conductive ring 3a and the transducer 2b. The conductive part 3f can be detachably connected to the transducer housing 2a, either wholly or partially. In this way, when the conductive component 3 is removed from the mounting part 4, the conductive part 3f can move entirely or partially along with the conductive ring 3a, thereby achieving detachment from the transducer housing 2a. This allows the conductive ring 3a to move synchronously with the conductive part, enabling the conductive ring 3a to achieve a plug-and-play connection function.

[0118] To enable the conductive part 3f to be detachably connected to the transducer housing 2a, either integrally or partially, in some embodiments, the conductive part 3f may adopt an integral structure or a split structure. Referring to Figures 1-14, taking the split structure of the conductive part 3f as an example, in some embodiments, the conductive part 3f may include a plurality of conductive connectors 3d electrically connected to the transducer 2b, and conductive members 3e corresponding to the number of conductive connectors (it can be understood that the corresponding number here means that all conductive connectors 3d and all conductive members 3e can form an electrical connection relationship. In some embodiments, the corresponding number means that the number of conductive connectors 3d and the number of conductive members 3e are equal).

[0119] In some embodiments, the conductive connector 3d is arranged along the axial direction of the blade body 1 on the front side of the conductive member 3e and is disposed in the housing portion 21a of the transducer housing 2a. In the axial direction of the blade body 1, one end of the conductive part 3f is electrically connected to the inner side of the conductive ring 3a and the other end is electrically connected to the transducer 2b. In this way, the conductive line between the conductive ring 3a and the transducer 2b can be avoided from being placed outside the cavity 5a and interfering with the fixing component 5. It can also make the arrangement path of the conductive line between the conductive ring 3a and the transducer 2b shorter and the electrical connection between the conductive ring 3a and the transducer 2b more stable.

[0120] In order to facilitate the electrical connection between the conductive connector 3d and the transducer 2b, in some embodiments, the housing portion 21a of the transducer housing 2a may be provided with an installation channel 210a that extends to the inner cavity 20a, and the conductive connector 3d is detachably connected in whole or in part to the installation channel 210a, so that the conductive component 3 can be detached from the transducer housing 2a along the axial direction of the blade 1.

[0121] In some embodiments, each conductive member 3e may have a columnar structure and be mounted on the conductive mounting portion 3b, and electrically connected to the corresponding conductive connector 3d. The conductive member 3e is mounted axially within the conductive mounting portion 3b along the blade body 1, located inside the conductive ring 3a, and electrically connected to the conductive ring 3a. In some embodiments, the number of conductive connectors 3d and conductive members 3e is at least matched to the number of conductors (e.g., conductive ring 3a). When the conductive ring 3a has a rear conductor 30a and a front conductor 31a, some conductive members 3e are electrically connected to the rear conductor 30a, and the remaining conductive members 3e are electrically connected to the front conductor 31a, such that the rear conductor 30a and the front conductor 31a respectively conduct the positive and negative terminals of the transducer 2b.

[0122] It is understandable that when there are multiple conductive rings 3a, the number of conductive components 3e can also be increased accordingly. In some embodiments, each conductive component 3e can be electrically connected to a conductive ring 3a in a one-to-one correspondence. Taking a conductive ring 3a including a rear conductor 30a and a front conductor 31a as an example, in some embodiments, there are two conductive components 3e, which can be electrically connected to the two conductive rings 3a respectively. That is, one conductive component 3e is only electrically connected to one conductive ring 3a, and the other conductive component 3e is only electrically connected to the other conductive ring 3a, so that some conductive components 3e are electrically connected to the rear conductor 30a, and the remaining conductive components 3e are electrically connected to the front conductor 31a, realizing the positive and negative polarity distribution in the connection circuit. In some embodiments, if the conductive component 3 is provided with only one conductive ring 3a, a partition structure needs to be provided inside the conductive ring 3a so that a single conductive ring 3a can achieve positive and negative polarity conduction. In this case, the conductive mounting part 3b only needs to be provided with one mounting groove 30b for mounting the conductive ring 3a.

[0123] It is understandable that the structure of the conductive connector 3d is diverse; it can be an integral structure or a detachable structure, as long as the conductive connector 3d can be inserted into the mounting channel 210a to achieve a conductive connection between the conductive ring 3a and the transducer 2b. For example, in some embodiments, the conductive connector 3d may include an insulating mounting base 30d and a conductive matching member 31d placed within the insulating mounting base 30d, with the conductive matching member 31d electrically connected to the transducer 2b. In some embodiments, the insulating mounting base 30d is arranged within the mounting channel 210a, such that the conductive matching member 31d is fixed to the transducer housing 2a, while the conductive member 3e is mounted on the conductive mounting portion 3b and fixed within the conductive assembly 3. In this way, when the conductive ring 3a is fitted onto the mounting part 4, the conductive member 3e can contact the conductive matching member 31d, so that the conductive ring 3a is connected to the transducer 2b. When the conductive ring 3a is removed from the mounting part 4, the conductive member 3e and the conductive matching member 31d are disconnected, thereby disconnecting the conductive ring 3a from the transducer 2b, thus realizing the insertion and assembly of the conductive ring 3a and the transducer 2b.

[0124] In specific applications, in some embodiments, the conductive member 3e can be a socket or a plug, and correspondingly, the conductive matching member 31d is a corresponding plug or socket. The insertion contact between the plug and the socket forms an electrical connection between each conductive member 3e and the corresponding conductive matching member 31d. In some embodiments, when the conductive ring 3a has a rear conductor 30a and a front conductor 31a, specifically, on one side of the transducer housing 2a, an insulating mounting base 30d is provided in the mounting channel 210a. The conductive matching members 31d (e.g., one-to-one correspondence) are installed in the insulating mounting base 30d and electrically connected to the transducer 2b through wires. One conductive matching member 31d is connected to the positive electrode plate of the transducer 2b, and the other conductive matching member 31d is connected to the negative electrode plate of the transducer 2b. This allows the conductive component 3e to be inserted into the conductive matching part 31d when the conductive component 3 is mounted on the mounting part 4, enabling the conductive ring 3a to conduct electricity with the transducer 2b, thereby ensuring a quick-connect electrical connection between the conductive component 3 and the transducer 2b. Furthermore, when the conductive component 3 is detached from the mounting part 4, the conductive matching part 31d separates from the conductive component 3e, allowing the conductive part to be detachably connected to the mounting channel 210a, and enabling the conductive component 3 to be connected to the transducer 2b via a plug-in connection, thus facilitating the disassembly and replacement of the entire conductive component 3.

[0125] Referring to Figure 13, in other examples, the conductive connector 3d can also adopt a mating structure of an insulating mounting base 30d and an elastic conductive sheet 32d. This structure includes an insulating mounting base 30d and an elastic conductive sheet 32d. The conductive member 3e is electrically connected to the conductive ring 3a, and the elastic conductive sheet 32d is electrically connected to the transducer 2b. The conductive member 3e and the elastic conductive sheet 32d contact to form an electrical connection. In this way, the conductive assembly 3 can also enable the conductive ring 3a to achieve conductive communication with the transducer 2b along the axial direction of the blade body 1.

[0126] Referring to Figures 2-4, as an example of the described embodiment, the front end face of the conductive mounting portion 3b is provided with receiving grooves 31b corresponding to the number of conductive members 3e (it can be understood that "corresponding to the number" here refers to the number of receiving grooves 31b provided, such that the number of receiving grooves 31b is sufficient to accommodate all conductive members 3e, and there will be no excess receiving grooves 31b. In some embodiments, "corresponding to the number" means that the number of conductive members 3e is equal to the number of receiving grooves 31b). The front end of each conductive member 3e is disposed in the receiving groove 31b, and the rear end face of each insulating mounting base 30d extends into the corresponding receiving groove 31b. This allows the conductive members 3e and the conductive matching parts 31d or elastic conductive sheets 32d to be quickly positioned and matched when the conductive ring 3a is sleeved on the mounting portion 4.

[0127] When the ultrasonic scalpel holder 100 is in operation, the conductive ring 3a comes into contact with the brush, generating heat through friction. Therefore, after prolonged operation, the conductive ring 3a will produce a large amount of heat and dust, affecting its service life. In some embodiments, a cooling air path is provided in the ultrasonic scalpel holder 100 to cool the conductive ring 3a and the transducer 2b, and to remove the dust generated by the conductive ring 3a during operation, thereby extending the service life of both the conductive ring 3a and the transducer 2b.

[0128] Referring to Figures 1-19, as an example of the described embodiment, the ultrasonic scalpel handle 100 further includes a conductive component cooling branch 15 for cooling the conductive component 3 and / or a transducer cooling branch 14 for cooling the transducer 2b; the inner cavity 20a communicates with its external space to form the transducer cooling branch 14, and / or the cavity 5a communicates with its external space to form the conductive component cooling branch 15 (in some embodiments, the external space here mainly refers to the external environment); to discharge gas in the cooling branch. In some embodiments, the fixing component 5 has an air inlet channel 16a communicating with an external cooling gas source, the air inlet channel 16a communicating with the transducer cooling branch 14 and the conductive component cooling branch 15 respectively, so that the airflow of the external cooling gas source can flow through the air inlet channel 16a to the cavity 5a and the inner cavity 20a. In some embodiments, the transducer cooling branch 14 is connected to the transducer assembly (such as the transducer housing 2a or the transducer 2b) and allows airflow to enter the interior of the inner cavity 20a from the outside to cool the transducer 2b. In some embodiments, the conductive component cooling branch 15 is connected to the conductive component 3 and allows airflow to flow to the outer periphery of the conductive ring 3a to cool it. Of course, depending on the application scenario of the ultrasonic scalpel handle 100, either the transducer cooling branch 14 or the conductive component cooling branch 15 can be used, or both can be used simultaneously.

[0129] In some embodiments, the fixing assembly 5 may further include an air passage pressure ring 16 to allow airflow to enter the transducer cooling branch 14 and / or the conductive component cooling branch 15 respectively. In some embodiments, the air passage pressure ring 16 is disposed on the outer periphery of the conductive ring 3a and close to the transducer housing 2a, forming a split air passage 17 between the air passage pressure ring 16 and the transducer housing 2a. The split air passage 17 is configured to introduce external air, allowing the introduced air to enter the transducer cooling branch 14 and / or the conductive component cooling branch 15 respectively. In some embodiments, the other end of the split air passage 17 is connected in parallel with the conductive component cooling branch 15 and / or the transducer cooling branch 14, allowing airflow to enter the transducer cooling branch 14 and / or the conductive component cooling branch 15 respectively.

[0130] It is understandable that the path design of the transducer cooling branch 14 and the conductive component cooling branch 15 is not unique. It is only necessary to ensure that the airflow flowing inside the transducer cooling branch 14 can cool the transducer 2b and the airflow flowing inside the conductive component cooling branch 15 can cool the conductive ring 3a.

[0131] As an example of the described implementation, the transducer cooling branch 14 can be designed as follows:

[0132] A gap is formed between the first bearing 8 and the transducer housing 2a. The transducer housing 2a contains a first transducer branch 14a arranged axially along the cutter body 1, a second transducer branch 14b arranged radially along the cutter body 1, and a third transducer branch 14c and a fourth transducer branch 14d connected to the inner cavity 20a. The first transducer branch 14a, the second transducer branch 14b, the gap, the third transducer branch 14c, the inner cavity 20a, and the fourth transducer branch 14d are sequentially connected to form a transducer cooling branch 14.

[0133] The first branch 14a of the transducer is located at the rear end of the transducer housing 2a and is connected to the intake channel 16a through the split air passage 17; one end of the second branch 14b of the transducer is connected to the first branch 14a of the transducer, and the other end is connected to the gap between the transducer housing 2a and the first bearing 8, which serves as a bearing component; one end of the third branch 14c of the transducer is connected to the gap between the transducer housing 2a and the first bearing 8, and the other end is connected to the inner cavity 20a; one end of the fourth branch 14d of the transducer is connected to the inner cavity 20a, and the other end is connected to the outside.

[0134] Specifically, as an example of the described embodiment, the transducer assembly also includes an amplitude transformer 33 fixedly connected to the transducer 2b. The flange portion 301a of the amplitude transformer 33 is connected to the inner wall of the transducer housing 2a, and a second through hole 300a is provided on the flange portion 301a. The second through hole 300a connects the inner cavity 20a with the external environment, forming the fourth branch 14d of the transducer.

[0135] In some embodiments, a transducer spiral air passage 18 extending axially along the blade body 1 may be provided on the outer periphery of the transducer housing 2a to form a gap between the transducer housing 2a and the first bearing 8, and to extend the flow distance of the airflow between the transducer housing 2a and the first bearing 8. The transducer spiral air passage 18 connects the second branch 14b and the third branch 14c of the transducer, so that after the airflow flows out from the second branch 14b of the transducer, it can flow along the spiral path defined by the transducer spiral air passage 18 to cool the first bearing 8.

[0136] It is understandable that the airflow path 17 formed by the air passage pressure ring 16 connects to the cavity 5a to cool the conductive ring 3a. In some embodiments, to ensure that the cooling airflow can blow towards the conductive ring 3a, the air passage pressure ring 16 is close to one end of the conductive component 3; in this way, the air passage pressure ring 16 is also close to the side wall of the annular groove 10, so the brush holder 6 can also be installed on the air passage pressure ring 16, so that the brush installed on the brush holder 6 can be slidably connected to the conductive ring 3a to achieve conductivity. As an example of the above embodiment, the air passage pressure ring 16 is installed on the bearing pressing part 9 as part of the fixing component 5.

[0137] Referring to Figures 1-19, as an example of the described embodiment, the cavity 5a containing the conductive ring 3a constitutes the conductive component cooling branch 15. Airflow entering the cavity 5a from the branch air passage 17 can cool the conductive ring 3a. In some embodiments, an upper air passage 15a is formed between the blade body 1 and the fixing component 5. This upper air passage 15a connects the outside to the inside of the fixing component 5, i.e., the cavity 5a, and is connected to the conductive component cooling branch 15.

[0138] In this way, after the airflow enters from the split air passage 17, it can enter the cavity 5a and the first branch passage 14a of the transducer, and then flow to the conductive ring 3a and the transducer 2b, respectively, to cool the conductive ring 3a and the transducer 2b. Furthermore, the airflow entering the cavity 5a can carry away the dust generated during the operation of the conductive ring 3a from the upper air passage 15a, ensuring the stability of the electrical connection between the conductive ring 3a and the brush, and extending the service life of the conductive component 3.

[0139] In some embodiments, the upper cover 5b extends radially into the front side of the blade body 1, and the outer side wall of the blade body 1 is provided with a flange 10c extending forward; and the upper cover 5b is provided with an upper groove 50b arranged around the blade body 1, and the flange 10c extends into the upper groove 50b to form an upper air passage 15a, and the cavity 5a communicates with the external environment through the upper air passage 15a.

[0140] By cooperating with the flange 10c of the blade body 1 and the upper groove 50b of the upper cover 5b, the upper air passage 15a can form a U-shaped passage, which can form a labyrinth seal to prevent external dust and other objects from entering the cavity 5a where the conductive ring 3a and the brush are located and affecting their electrical connection.

[0141] In some embodiments, the ultrasonic scalpel holder 100 employs a parallel air path design, allowing external airflow to enter through the inlet channel 16a and then be diverted to the transducer cooling branch 14 and / or the conductive component cooling branch 15, simultaneously cooling the transducer 2b and the conductive component 3. In the cooling air path of the ultrasonic scalpel holder 100, the inlet channel 16a serves to connect to an external cooling air source and obtain cooling airflow. In some embodiments, the inlet channel 16a can be a normally open air path or an air path equipped with an opening and closing structure.

[0142] Referring to Figures 1-19, as an example of the described embodiment, the fixing component 5 has a first channel 161a and a side channel 162a, and a first through hole 160a is formed on the side wall of the outer casing 5c. The first channel 161a is connected to an external cooling air source. A diversion air path 17 is formed between the inner ring side of the air passage pressure ring component 16 and the transducer housing 2a. A pressure ring air path 16b connected to the diversion air path 17 is provided on the outer ring side of the air passage pressure ring component 16. The side channel 162a is connected to the pressure ring air path 16b through the first through hole 160a. The first channel 161a, the side channel 162a, the first through hole 160a, and the pressure ring air path 16b are sequentially connected to form an air intake channel 16a. At this time, the first channel 161a and the side channel 162a are located on the outside of the outer casing 5c ​​and can be connected to an external cooling air source. In some embodiments, the upper cover 5b and the receiver 5e may also be an integral structure; for example, in some embodiments, the first channel 161a and the lateral channel 162a are provided on the upper cover 5b or the receiver 5e. Figures 20 and 23 show the upper cover 5b and the receiver 5e integrally formed.

[0143] To introduce airflow into the split air passage 17, referring to Figures 1-19, as an example of the described embodiment, a hollow guide nozzle 19 is provided on the fixing assembly 5. In some embodiments, one end of the guide nozzle 19 extends into the air intake channel 16a, and the guide nozzle 19 is movable in the air intake channel 16a along the axial direction of the cutter body 1. The other end of the guide nozzle 19 is connected to an external cooling air source to supply cooling airflow to the air intake channel 16a.

[0144] In some embodiments, a nozzle elastic element 20 is provided between the guide nozzle 19 and the fixing component 5. One end of the nozzle elastic element 20 is connected to the air inlet channel 16a, and the other end extends into the guide nozzle 19, allowing the guide nozzle 19 to move relative to the fixing component 5 along the axial direction of the blade body 1. Furthermore, the guide nozzle 19 is connected to the split air passage 17 and to the outside of the fixing component 5 to form a cooling air inlet path. This ensures that when the ultrasonic scalpel handle 100 is assembled, the guide nozzle 19, driven by the elastic force of the nozzle elastic element 20, presses against the supply end of the external cooling air source, allowing the cooling airflow from the external cooling air source to enter the air inlet channel 16a through the guide nozzle 19.

[0145] In conjunction with the aforementioned transducer cooling branch 14 and / or conductive component cooling branch 15, in some embodiments, the ultrasonic scalpel holder 100 can achieve the following flow path and allow the airflow to flow along the sufficient flow path:

[0146] The air passage pressure ring 16 has an annular structure and is arranged around the cutter body 1, forming a split air passage 17 between the air passage pressure ring 16 and the transducer housing 2a. The split air passage 17 also has an annular structure and is arranged around the cutter body 1. The air passage pressure ring 16 also has an air inlet channel 16a that communicates with the split air passage 17, and the air inlet channel 16a is also connected to the guide nozzle 19. The bearing cap 7 is used to limit the axial direction of the first bearing 8. It is installed at the rear end of the housing part 21a, and its rear end face is flush with the rear end face of the housing part 21a. Therefore, the split air passage 17 is also the air passage between the air passage pressure ring 16 and the bearing cap 7.

[0147] After the gas flows out of the guide nozzle 19, it enters the split gas path 17 through the intake passage 16a, and then splits into two paths within the split gas path 17:

[0148] One path leads to the transducer cooling branch 14, specifically through the first transducer branch 14a, the second transducer branch 14b, the transducer spiral air passage 18, and the third transducer branch 14c, entering the inner cavity 20a of the transducer housing 2a to cool the transducer 2b and extend its service life. Finally, the gas exits along the fourth transducer branch 14d, i.e., from the second through hole 300a located in the flange portion 301a; and / or

[0149] Another path enters the conductive component cooling branch 15, specifically through the cooling gap between the air passage pressure ring 16 and the conductive mounting part 3b, entering the cavity 5a of the fixing component 5 to cool the conductive ring 3a. Then, it enters the gap between the upper cover 5b and the conductive cover part 3c, and finally exits from the upper air passage 15a, i.e., the gap between the blade body 1 and the upper cover 5b, thereby blowing out the dust generated by the wear of the conductive ring 3a and the brush, ensuring the stability of the electrical connection and extending the service life of the conductive component 3.

[0150] In some embodiments, when the ultrasonic scalpel handle 100 is in operation, it typically receives an electrical signal through the transmitter 24 and transmits the signal to the transducer 2b through the conductive component 3. Since the scalpel body 1 can rotate relative to the fixing component 5, after the scalpel body 1 is detached from the spindle, relative rotation will occur between the scalpel body 1, the fixing component 5, and the conductive component 3. At this time, the power-consuming contact 26 (i.e., the receiving part) located on the end face of the fixing component 5 may deviate from its current position. This means that when the ultrasonic scalpel handle 100 is reconnected to the spindle, the power-consuming contact 26 of the fixing component 5 will not directly contact the power supply contact 25 (i.e., the power supply part) of the transmitter 24. Consequently, the transmitter 24 will be unable to transmit the electrical signal to the conductive component 3. To address this issue, in some embodiments, a positioning component 21 can be provided on the ultrasonic scalpel handle 100 to restrict the relative rotation between the scalpel body 1 and the fixing component 5 when the scalpel body 1 is detached from the spindle.

[0151] Referring to Figures 1-14 and 20-25, as an example of the described embodiment, the ultrasonic scalpel handle 100 further includes a positioning component 21. The positioning component 21 is disposed on the outer periphery of the scalpel body 1 and arranged on the upper cover 5b. The scalpel body 1 is provided with a positioning groove 22 arranged circumferentially along the scalpel body 1. The positioning component 21 is configured to move toward the scalpel body 1 and extend into the positioning groove 22, so that the scalpel body 1 and the fixing component 5 are relatively stationary. It can also move away from the scalpel body 1 to disengage from the positioning groove 22, so that the scalpel body 1 and the fixing component 5 can rotate relative to each other.

[0152] In some embodiments, a positioning groove 51b is provided on the upper end surface of the upper cover 5b, and the positioning groove 51b communicates with the positioning slot 22; the positioning component 21 is disposed in the positioning groove 51b. In some embodiments, the positioning component 21 and the power-side contact 26 are located on the same side of the blade body 1 to facilitate the structural layout of the ultrasonic scalpel handle 100. Specifically, when the ultrasonic scalpel handle is mounted on the spindle, the transmitter on the spindle side can act on the positioning component.

[0153] In some embodiments, the positioning component 21 includes a slider group and a top block 21c, wherein the slider group includes an upper slider 21e and a lower slider 21b arranged sequentially along the circumference of the cutter body 1.

[0154] The upper slider 21e can reciprocate along the axis of the cutter body 1, and the upper slider 21e is provided with a first inclined surface 210e on the side away from the cutter body 1. The first inclined surface 210e is inclined from top to bottom, that is, from the rear side to the front side towards the cutter body 1.

[0155] The lower slider 21b can reciprocate towards or away from the cutter body 1. The lower slider 21b is connected to the top block 21c. A second inclined surface 210b is provided on the side of the lower slider 21b facing the cutter body 1. The second inclined surface 210b is inclined downwards towards the cutter body 1, allowing the first inclined surface 210e and the second inclined surface 210b to slide relative to each other. This causes the upper slider 21e to move forward, pressing the lower slider 21b and moving it away from the cutter body 1, thereby causing the top block 21c to disengage from the positioning groove 22. Conversely, when the upper slider 21e moves backward, the lower slider 21b loses the axial pressure on the cutter body 1, eliminating its tendency to move away from the cutter body 1 and allowing it to approach the cutter body 1.

[0156] In some embodiments, the lower slider 21b is provided with a locking groove 211b, and the top block 21c is embedded in the locking groove 211b, so that the top block 21c and the lower slider 21b move synchronously. That is, the top block 21c is connected to the lower slider 21b and can move synchronously with the lower slider 21b. Furthermore, the upper slider 21e is provided with a lower notch 212e on the side facing the cutter body 1. The lower slider 21b passes through the lower notch 212e and extends towards the side where the cutter body 1 is located, realizing the connection with the top block 21c. This also allows the upper slider 21e and the lower slider 21b to form a constrained fit in the axial direction of the cutter body 1 using the lower notch 212e, so that the upper slider 21e and the lower slider 21b will not separate during relative movement. Moreover, it can prevent interference between the lower slider 21b and the upper slider 21e when the lower slider 21b moves towards the cutter body.

[0157] In some embodiments, the top block 21c is configured to reciprocate towards or away from the cutter body 1, causing the top block 21c to extend into or disengage from the positioning groove 22. In some embodiments, the positioning assembly 21 further includes a positioning elastic member 23, with the top block 21c abutting against the positioning elastic member 23. The positioning elastic member 23 is configured to compress the top block 21c, applying a force to the top block 21c to move it towards the cutter body 1, causing the top block 21c to extend into the positioning groove 22. Since the top block 21c moves synchronously with the lower slider 21b, the lower slider 21b can drive the upper slider 21e to rise.

[0158] When the ultrasonic scalpel handle 100 is connected to the spindle via the aforementioned positioning component 21, the upper slider 21e can be compressed, causing it to move forward and the lower slider 21b, along with the top block 21c, to move away from the scalpel body 1, thereby causing the top block 21c to exit the positioning groove 22 of the scalpel body 1. When the ultrasonic scalpel handle 100 is disengaged from the spindle, the upper slider 21e loses its compression, and the positioning elastic element 23 compresses the top block 21c, applying a force to the top block 21c to move it toward the scalpel body 1. Under the action of the positioning elastic element 23, the top block 21c extends into the positioning groove 22 and drives the lower slider 21b to move closer to the blade body 1. As a result, the upper slider 21e moves to the rear under the action of the first inclined surface 210e and the second inclined surface 210b, protruding from the upper cover 5b. This allows the upper slider 21e to be squeezed again when the ultrasonic scalpel handle 100 is next connected to the spindle, so that the positioning component 21 performs the aforementioned action again, causing the top block 21c to exit the positioning groove 22 of the blade body 1.

[0159] It is understandable that the structural design of the top block 21c is diverse. The top block 21c only needs to be able to be driven by the lower slider 21b to extend into the positioning groove 22, and be able to be driven by the positioning elastic member 23 to disengage from the positioning groove 22. Referring to Figures 1-14 and 20-25, as an example of the above embodiment, the top block 21c may include a first guide section 210c and a second guide section 211c. The first guide section 210c and the second guide section 211c are set at an angle. Furthermore, the first guide section 210c is located on the side of the second guide section 211c closer to the blade body 1, so that one end of the first guide section 210c can extend into the positioning groove 22, and the other end is connected to the second guide section 211c. The second guide section 211c is connected to the slider assembly. In this way, the movement of the lower slider 21b can cause the first guide section 210c of the top block 21c to reciprocate in and out of the positioning groove 22, which can make the cutter body 1 and the fixed component 5 relatively stationary and the cutter body 1 and the fixed component 5 relatively rotatable.

[0160] Furthermore, to ensure smooth movement of the top block 21c, in some embodiments, both the slider group and the positioning elastic element 23 can be in two groups, each located on the side of the second guide segment 211c away from the cutter body 1. Each slider group is connected to both ends of the second guide segment 211c, and each positioning elastic element 23 is spaced apart between the two slider groups and connected to the second guide segment 211c. In some embodiments, the first guide segment 210c is perpendicular to the second guide segment 211c, and the first guide segment 210c is arranged radially along the cutter body 1. In this way, the movement of the slider group or the positioning elastic element 23 can exert a radial force on the top block 21c along the cutter body 1, and this force is distributed on both sides of the first guide segment 210c, allowing the top block 21c to smoothly enter and exit the positioning groove 22.

[0161] It is understood that in some embodiments, there may be multiple positioning slots 22. In this way, when the blade body 1 is initially adjusted, the relative position of its position with the fixing component 5 can be calibrated by the positions determined by the multiple positioning slots 22, so that after the top block 21c extends into the positioning slot 22 to lock the position of the blade body 1, the power supply side contact 26 provided on the end face of the fixing component 5 can maintain the position corresponding to the power supply side contact 25.

[0162] In some embodiments, when the ultrasonic scalpel handle 100 is disengaged from the spindle, the upper slider 21e should protrude from the fixing component 5 and extend beyond the upper cover 5b, so that when the ultrasonic scalpel handle 100 is engaged with the spindle, the upper slider 21e can be more easily squeezed and moved forward. In order to limit the travel of the upper slider 21e in the axial direction of the blade body 1 and prevent the upper slider 21e from disengaging, referring to FIG1, as an example of the above embodiment, the positioning component 21 also includes a slider cover 21d located above the positioning groove 51b. The slider cover 21d is disposed on the movement path of the upper slider 21e to limit the upward travel of the upper slider 21e, that is, the displacement of the positioning component 21 in the axial direction of the blade body 1. In some embodiments, the slider cover 21d is provided with a guide hole 210d, which extends through the slider cover 21d along the axial direction of the cutter body 1. Furthermore, the upper slider 21e is provided with a guide portion 211e extending along the axial direction of the cutter body 1, which extends into the guide hole 210d to guide the movement direction of the upper slider 21e. In some embodiments, the slider cover 21d may also cover other parts of the positioning groove to define the lower slider and the top block, preventing them from dislodging from the positioning groove.

[0163] In some embodiments, after the upper slider 21e moves a certain distance rearward along the axial direction of the cutter body 1, it will abut against the slider cover 21d and cannot disengage from the slider cover 21d. In some embodiments, the stroke limited by the slider cover 21d should be sufficient to allow the top block 21c to disengage from the positioning groove 22.

[0164] Based on the aforementioned ultrasonic shovel 100, embodiments of this application also provide an ultrasonic processing device 200, including the aforementioned ultrasonic shovel 100, and further including a transmitter 24. A power supply side contact 25 (i.e., a power supply side connection end) is mounted on the transmitter 24, and a power use side contact 26 (i.e., a power use side connection end) is mounted on the upper cover 5b of the ultrasonic shovel 100. The power supply side contact 25 and the power use side contact 26 are in surface contact to form an electrical connection, and the power use side contact 26 is electrically connected to the conductive component 3. Compared to point contact, surface contact between the power supply side contact 25 and the power use side contact 26 can achieve a better electrical connection effect. In some embodiments, by installing a positioning component 21 at the location of the power use side contact 26, i.e., the upper cover 5b, the positioning component 21 can lock the relative position of the upper cover 5b and the shovel body 1, ensuring that the power use side contact 26 is connected to the power supply side contact 25.

[0165] In some embodiments, referring to Figures 1-25, the transmitter 24 is provided with a second channel 27 having a stepped portion 27a. The second channel 27 communicates with the air intake channel 16a and can be connected to an external cooling air source to supply cooling airflow to the air intake channel 16a. In some embodiments, one end of the guide nozzle 19 extends into the air intake channel 16a, and the other end of the guide nozzle 19 can extend into the second channel 27, so that the air intake channel 16a and the second channel 27 are connected. This allows the guide nozzle 19 to connect the second channel 27 and the air intake channel 16a when the transmitter 24 is connected to the ultrasonic scalpel handle 100, allowing the cooling airflow supplied by the external cooling air source to enter the air intake channel 16a.

[0166] In some embodiments, an air core 28 is provided within the second channel 27, passing through the step portion 27a, and an air core elastic member 29 is provided between the air core 28 and the step portion 27a, allowing the air core 28 to move axially along the blade body 1. When the air core 28 moves towards the step portion 27a, it can compress the air core elastic member 29, which in turn applies a force to the air core 28, causing it to move away from the step portion 27a and press against the guide nozzle 19.

[0167] In some embodiments, the air core 28 has an air core passage 28a extending through its rear end, which communicates with the second channel 27. Furthermore, the side wall of the air core 28 has an air inlet 28b near its rear end, which communicates with the air core passage 28a and the second channel 27. In some embodiments, a sealing groove 28c is provided behind the air inlet 28b along the axial direction of the cutter body 1, and a sealing ring 13 can be filled in the sealing groove 28c. In some embodiments, under the action of the air core elastic member 29, the air core 28 tends to move away from the step portion 27a, causing the sealing ring 13 installed in the sealing groove 28c to press against the step portion 27a. This seals the sealing groove 28c with the rear end face of the step portion 27a through the sealing ring 13, thus closing the second channel 27 and preventing it from communicating with the air inlet 28b.

[0168] When in use, the ultrasonic scalpel holder 100 is mounted to the spindle. When the ultrasonic scalpel holder 100 is in place, the power supply side contact 25 of the transmitter 24 is connected to the power consumption side contact 26 of the upper cover 5b, so that the electrical signal can be connected to the transducer 2b. Meanwhile, the air core 28 installed in the launcher 24 can be pressed against the guide nozzle 19 under the elastic force of the air core elastic element 29. The front end of the air core 28 and the rear end of the guide nozzle 19 abut against each other, so that the air core passage 28a is connected to the guide nozzle 19, so that the air core passage 28a is connected to the air intake passage 16a. Furthermore, based on the action of the nozzle elastic element 20, the guide nozzle 19 can squeeze the air core 28, causing the air core 28 to move towards the step portion 27a, thereby causing the sealing ring 13 installed on the air core 28 to disengage from the step portion 27a, and the air intake hole 28b of the air core 28 is connected to the outside. In this way, external air can enter the air core passage 28a from the air intake hole 28b, and enter the diversion air path 17 through the guide nozzle 19 and the air intake passage 16a.

[0169] When the ultrasonic scalpel holder 100 is detached from the spindle, the air core 28 moves away from the guide nozzle 19. As a result, the air core 28 can move away from the step portion 27a under the action of the air core elastic element 29, so that the sealing ring 13 installed in the sealing groove 28c is pressed onto the step portion 27a, sealing the second channel 27.

[0170] Based on the aforementioned ultrasonic processing equipment 200, embodiments of this application also provide a machine tool, including a machine tool body, a spindle disposed on the machine tool body, and the aforementioned ultrasonic processing equipment 200, with a transmitter 24 mounted on the spindle.

[0171] In summary, the embodiments of the present invention provide an ultrasonic scalpel holder 100 that forms a mounting portion 4 by detachably connecting a scalpel body 1 and a transducer housing 2a, allowing the conductive component 3 to be fitted onto the mounting portion 4. This enables the conductive ring 3a to adopt an integral structure, and the outer diameter of the conductive ring 3a in the radial direction of the scalpel body 1 is less than or equal to the outer diameter of the transducer housing 2a adjacent to the mounting portion 4. By reducing the outer diameter of the conductive ring 3a, the linear velocity of the conductive ring 3a is reduced, and the heat generated by the conductive ring 3a is reduced, thereby improving the service life of the conductive component 3. This solves the problems of high conductive ring linear velocity and severe heat generation in existing ultrasonic scalpel holders, making it difficult for ultrasonic scalpel holders to be used for high-speed machining. Furthermore, since the conductive component 3 is fitted onto the mounting portion 4 formed by the connection between the blade body 1 and the transducer housing 2a, changes in the size of the conductive component 3 will not affect the specifications of the inner cavity 20a of the transducer housing 2a, that is, will not affect the specifications of the transducer 2b. Therefore, even if the ultrasonic scalpel handle 100 of the present invention adjusts the size of the conductive ring 3a according to functional requirements, it can ensure that the power of the transducer 2b is not affected and the normal operation of the ultrasonic scalpel handle 100 is not affected.

[0172] Furthermore, the ultrasonic scalpel holder 100 of the aforementioned embodiment adds a transducer cooling branch 14 and / or a conductive component cooling branch 15. The transducer 2b and the conductive component 3 are cooled by the transducer cooling branch 14 and / or the conductive component cooling branch 15. Compared with the central cooling design adopted by the existing ultrasonic scalpel holder 100, the cooling air path structure of this ultrasonic scalpel holder 100 is simple. It can also blow out the dust generated by the wear of the conductive ring 3a and the brush, further reducing the heat generation of the conductive ring 3a. In addition, the cooling air path of this ultrasonic scalpel holder 100, through the addition of a guide nozzle 19 and a nozzle elastic element 20, can effectively prevent the problem of component damage caused by the misalignment between the transmitter 24 and the fixing component 5.

[0173] Furthermore, the ultrasonic tool holder 100 of the above embodiment, by providing a positioning component 21, can lock the current position of the tool body 1 when the spindle is disengaged from the tool body 1, so that the tool body 1 and the receiving part can remain relatively stationary. Moreover, when the ultrasonic tool holder is mounted on the spindle, the tool body and the receiving seat can rotate relative to each other. Embodiments of this application also provide an ultrasonic processing apparatus 200 and a machine tool that utilize the aforementioned ultrasonic tool holder 100 and have the aforementioned beneficial effects of the ultrasonic tool holder 100.

[0174] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and substitutions without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
