Description

[0002] When manufacturing and processing parts, machine tools can use ultrasonic processing equipment to process part blanks. Specifically, by supplying power to the transducer installed in the ultrasonic tool holder of the ultrasonic processing equipment, the transducer generates ultrasonic vibration, which drives the tool installed in the ultrasonic tool holder to vibrate, thereby processing the part blank under high-frequency vibration.

[0003] In existing technologies, the cutter body and transducer housing are designed as separate units, but are fixed together during assembly. Both the front end of the cutter body and the rear end of the transducer housing have protrusions that are nested together. At the connection point, both protrusions occupy the radial space of the ultrasonic shovel. Due to the limited radial space of the ultrasonic shovel, it is difficult to ensure that both protrusions have suitable wall thicknesses simultaneously. Therefore, the connection strength between the cutter body and the transducer housing is low. When the ultrasonic shovel drives the transducer housing to rotate at high speed, the connection is prone to breakage, affecting the reliability of the ultrasonic shovel and consequently the product quality of the ultrasonic processing equipment. Summary of the Invention

[0004] The purpose of this application is to improve the strength of the connection between the cutter body and the transducer housing, prevent the connection between the two from breaking when the cutter body drives the transducer housing to rotate at high speed, thereby improving the working reliability of the ultrasonic cutter handle and thus improving the product quality of the ultrasonic processing equipment.

The side wall of the tool changing ring away from the protrusion is provided with a tool changing groove, which extends circumferentially along the protrusion.

[0017] In some examples of this application, the ultrasonic scalpel handle further includes: an air guide seat, which is rotatably sleeved on the outer periphery of the protrusion via the bearing.

[0018] In some examples of this application, the ultrasonic scalpel handle further includes: a heat exchange sleeve, which is sleeved on the outer periphery of the bearing and sandwiched between the bearing and the air guide seat. The heat exchange sleeve is provided with a heat exchange channel, which communicates with the air guide channel and the receiving cavity.

The portion of the transducer housing that forms the communicating cavity has an air passage, and the air passage connects the communicating cavity and the receiving cavity.

[0022] The ultrasonic processing equipment according to this application includes: the ultrasonic tool holder described above.

[0023] According to the ultrasonic processing equipment of this application, the ultrasonic processing equipment is equipped with an ultrasonic tool holder. By setting a protrusion between the transducer housing and the tool body of the ultrasonic tool holder, the protrusion is inserted into the tool body or the transducer housing to achieve the connection between the tool body and the transducer housing. Compared with the prior art, the wall thickness of a single protrusion is larger, which can improve the strength of the connection between the tool body and the transducer housing. It can prevent the connection between the two from breaking when the tool body drives the transducer housing to rotate at high speed, thereby improving the working reliability of the ultrasonic tool holder and thus improving the product quality of the ultrasonic processing equipment.

[0024] The machine tool according to this application includes: a machine tool body; a spindle, the spindle being mounted on the machine tool body, the machine tool body being used to drive the spindle to rotate about the central axis of the spindle; and the aforementioned ultrasonic processing equipment, wherein the ultrasonic tool holder of the ultrasonic processing equipment is connected to the spindle.

[0025] According to the machine tool of this application, the machine tool is equipped with an ultrasonic processing device, and the ultrasonic processing device is equipped with an ultrasonic tool holder. When the machine tool uses the ultrasonic processing device to process a workpiece, when the spindle drives the transducer housing to rotate through the tool body, a protrusion is provided between the transducer housing and the tool body of the ultrasonic tool holder. The protrusion is inserted into the tool body or the transducer housing to achieve the connection between the tool body and the transducer housing. Compared with the prior art, the wall thickness of a single protrusion is larger, which can improve the strength of the connection between the tool body and the transducer housing. It can prevent the connection between the two from breaking when the tool body drives the transducer housing to rotate at high speed, thereby improving the working reliability of the ultrasonic tool holder and thus improving the product quality of the ultrasonic processing equipment.

[0026] Compared with the prior art, the ultrasonic tool holder, ultrasonic processing equipment, and machine tool implemented in this application have the following advantages:

[0027] 1. By setting a protrusion between the transducer housing and the blade body, the protrusion is inserted into the blade body or the transducer housing to achieve the connection between the blade body and the transducer housing. Compared with the prior art, the wall thickness of a single protrusion is larger, which can improve the strength of the connection between the blade body and the transducer housing. It can prevent the connection between the two from breaking when the blade body drives the transducer housing to rotate at high speed, thereby improving the working reliability of the ultrasonic blade holder and thus improving the product quality of the ultrasonic processing equipment.

[0028] 2. By setting a first wire channel in the blade body and a second wire channel in the protrusion, and connecting the connection hole to the receiving cavity, one end of the wire is electrically connected to the receiving unit, and the other end passes through the first wire channel and the second wire channel in sequence and extends into the receiving cavity, so that the other end of the wire is electrically connected to the transducer. Compared with the prior art, there is no need to open a hole on the transducer housing to avoid the wire, which can reduce the processing difficulty of the ultrasonic scalpel handle.

[0029] 3. The heat exchange bushing is located inside the tool changing ring. Compared with setting the heat exchange bushing at the front or rear end of the tool changing ring, this setting can ensure that the heat exchange bushing has a good heat exchange effect on the bearing. At the same time, it can avoid the heat exchange bushing affecting the tool changing process of the tool changing ring. It can also eliminate the need to extend the axial length of the ultrasonic scalpel handle, making the ultrasonic scalpel handle structure compact. Attached Figure Description

[0048] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0049] like Figures 1-10 As shown in the figure, this application discloses an ultrasonic processing device 1000 and an ultrasonic tool holder 100. The ultrasonic processing device 1000 includes an ultrasonic tool holder 100 and a cutting tool 400, as shown in the figure. Figure 1 , Figure 3As shown, an ultrasonic tool holder 100 is equipped with a transducer 200 and an amplitude transformer 300. The ultrasonic tool holder 100 includes a transducer housing 2, in which the transducer 200 is installed. The amplitude transformer 300 is installed at the front end of the transducer 200, extending out of the transducer housing 2 from the end furthest from the spindle. A cutting tool 400 is installed at the end of the amplitude transformer 300 outside the transducer housing 2. The transducer 200 is used to convert electrical energy into high-frequency vibration, the amplitude transformer 300 is used to conduct vibration and amplify the vibration amplitude generated by the transducer 200, and the cutting tool 400 is used to receive vibration and process the workpiece. The rear end of the ultrasonic tool holder 100 is connected to the spindle.

[0050] like Figures 1-10 As shown, the ultrasonic scalpel handle 100 described in this embodiment includes: a scalpel body 1, the aforementioned transducer housing 2, and a protrusion 3. The scalpel body 1 has a first end and a second end arranged opposite to each other along the front-rear direction of the ultrasonic scalpel handle 100. It should be noted that the front-rear direction of the ultrasonic scalpel handle 100 can refer to... Figure 1 The front-back direction in the middle, that is, the first end of the blade 1 refers to Figure 1 The front end of the middle blade 1, the second end of the blade 1 refers to Figure 1 The rear end of the middle cutter body 1, the second end of the cutter body 1 (i.e. the rear end of the cutter body 1), is adapted to be connected and engaged with the spindle. The second end of the cutter body 1 is provided with a receiving groove and a positioning notch. The positioning notch is located on the outer periphery of the receiving groove and is connected to the receiving groove. The spindle is adapted to be inserted into the receiving groove, and the positioning unit on the spindle is adapted to be inserted into the positioning notch. When the spindle drives the positioning unit to rotate, the positioning unit engages with the positioning notch, which allows the cutter body 1 to rotate around the central axis of the cutter body 1.

[0051] Furthermore, the transducer housing 2 is provided with a receiving cavity 21 for accommodating the transducer 200. It is understood that the transducer 200 generally includes a piezoelectric vibrator, which is used to convert electromagnetic energy into mechanical energy. The specific working principle of the transducer 200 is well-documented in existing technologies and will not be elaborated upon here. The transducer housing 2 is coaxially arranged with the blade body 1, and the axial direction of both the transducer housing 2 and the blade body 1 is consistent with the front-rear direction of the ultrasonic scalpel handle 100. The transducer housing 2 is located on the side of the blade body 1 away from the main shaft, i.e., at the first end of the blade body 1. Furthermore, the transducer 200, transducer housing 2, and blade body 1 are coaxially arranged in pairs. This reduces the eccentric force generated by the transducer 200 when the blade body 1 drives the transducer 200 to rotate via the transducer housing 2, thereby reducing the mechanical vibration generated by the ultrasonic scalpel handle 100.

[0052] Furthermore, a receiving unit 5 is provided on the outer periphery of the blade body 1, wherein the receiving unit 5 can be a wireless receiving unit 5 or a conductive ring. For example... Figure 1 , Figure 3As shown, this application will be described using the receiving unit 5 as the wireless receiving unit 5. In some preferred embodiments, the wireless receiving unit 5 is sleeved on the outer peripheral wall of the blade body 1, and the wireless receiving unit 5 can be detachably connected to the blade body 1. For example, the wireless receiving unit 5 can be connected to the blade body 1 by fasteners such as bolts or locking pins. Of course, in some embodiments, the wireless receiving unit 5 can be fixedly connected to the blade body 1. For example, the wireless receiving unit 5 can be fixedly connected to the blade body 1 by welding, riveting, or other methods. The wireless receiving unit 5 is suitable for electrical connection with the transducer 200. An external power supply first supplies power to the wireless receiving unit 5, and then the wireless receiving unit 5 supplies power to the transducer 200. The transducer 200 receives the electrical energy and converts the electrical energy into high-frequency vibration.

[0053] The wireless receiving unit 5 may include a receiving magnet and a receiving coil. The receiving coil is disposed within the receiving magnet and is electrically connected to the transducer 200. In some specific embodiments, a wire-passing channel is provided within the cutter body 1 to avoid wires, allowing the wires to connect between the transducer 200 and the receiving coil. How the wire-passing channel is provided within the cutter body 1 will be described in detail below.

[0054] Correspondingly, a wireless transmitting unit can be installed on the spindle of the machine tool. The wireless transmitting unit includes a transmitting magnet and a transmitting coil. The transmitting coil is installed inside the transmitting magnet and is electrically connected to an external power source. When the spindle of the machine tool is connected and engaged with the tool body 1 of the ultrasonic tool holder 100, the wireless transmitting unit and the wireless receiving unit 5 face each other. Power is supplied to the transmitting coil through the external power source, causing the transmitting magnet to generate a magnetic field. The wireless receiving unit 5 is located within the magnetic field generated by the wireless transmitting unit. Based on the principle of magneto-electric induction, the receiving coil can generate current and supply power to the transducer 200, thereby enabling the transducer 200 to convert electrical energy into high-frequency vibration.

[0055] By using a non-contact power supply method to power the ultrasonic tool holder 100, the heat generated by the ultrasonic tool holder 100 during operation can be reduced. When the machine tool drives the ultrasonic tool holder 100 to rotate at high speed, for example, when the rotation speed of the tool body 1 reaches 20,000 to 40,000 revolutions per minute, the non-contact power supply method can significantly reduce the heat generated by the ultrasonic tool holder 100 during operation, which helps to extend the service life of the ultrasonic tool holder 100.

[0056] Furthermore, one of the blade body 1 and the transducer housing 2 is provided with a protrusion 3. The protrusion 3 is inserted into and fixed inside the other blade body 1 and the transducer housing 2. That is, the blade body 1 is provided with a protrusion 3, and the protrusion 3 is inserted into and fixed inside the transducer housing 2, or the transducer housing 2 is provided with a protrusion 3, and the protrusion 3 is inserted into and fixed inside the blade body 1. The protrusion 3 is fixedly connected to the blade body 1 and to the transducer housing 2. Alternatively, the protrusion 3 is integrally formed with the blade body 1 and the transducer housing 2, which can achieve the technical effect of indirect or direct fixed connection between the blade body 1 and the transducer housing 2.

[0057] Therefore, by providing a protrusion 3 between the transducer housing 2 and the blade 1, the protrusion 3 can be inserted into the blade 1 or the transducer housing 2 to achieve the connection between the blade 1 and the transducer housing 2. Compared with the prior art, when the radial space inside the ultrasonic scalpel handle 100 is limited, setting the protrusion 3 as one allows for a larger wall thickness of the single protrusion 3, which can improve the strength of the connection between the blade 1 and the transducer housing 2. This can prevent the connection from breaking when the blade 1 drives the transducer housing 2 to rotate at high speed (e.g., 20,000 to 40,000 revolutions per minute), thereby improving the working reliability of the ultrasonic scalpel handle 100 and thus improving the product quality of the ultrasonic processing equipment 1000.

[0058] In addition, such as Figure 3 , Figure 4 As shown, after the protrusion 3 is fixedly connected to the blade body 1 and the transducer housing 2, a portion of the structure of the protrusion 3 is located outside the blade body 1 and the transducer housing 2 to separate them. An installation gap 31 is formed on the outer periphery of the portion of the protrusion 3 located outside the blade body 1 and the transducer housing 2. The installation gap 31 is located between the blade body 1 and the transducer housing 2 and is used to install the bearing 4. The inner ring 41 of the bearing 4 is fixedly connected to the protrusion 3, and the outer ring 42 of the bearing 4 is fixedly connected to the outer housing of the ultrasonic scalpel handle 100, allowing the outer housing of the ultrasonic scalpel handle 100 to rotate relative to the blade body 1. The outer housing of the ultrasonic scalpel handle 100 is used to protect the internal structure of the ultrasonic scalpel handle 100 and to install various functional components of the ultrasonic scalpel handle 100. For example, the outer housing of the ultrasonic scalpel handle 100 can be constructed as a wind guide seat 7, the specific structure of which will be described in detail below.

[0059] During the assembly of the ultrasonic shovel handle 100, the bearing 4 can first be fitted onto the outside of the protrusion 3. Furthermore, the ultrasonic handle also includes a bearing cap, which is fitted onto the outer periphery of the protrusion and mounted on the end of the bearing 4 near the transducer housing 2. By utilizing the bearing 4 to rotate the air guide seat 7 relative to the shovel body 1, the spindle can drive only a portion of the structure within the ultrasonic shovel handle 100 to rotate. Since the ultrasonic shovel handle 100 is in a high-speed rotating state, the introduction of airflow from the outside must not affect the rotation of the shovel body 1; therefore, the bearing 4 is used to achieve relative rotation between the two. Compared to driving the ultrasonic shovel handle 100 to rotate as a whole, this design also makes it easier for the shovel body 1 to achieve dynamic balance, reducing the runout of the tool 400, thereby improving the machining accuracy of the ultrasonic processing equipment 1000.

[0060] like Figures 5-7 As shown, in some embodiments of this application, the protrusion 3 is fixed to the first end of the blade body 1 (i.e., Figure 1 The front end wall of the middle blade body 1 is fixed with a protrusion 3 and a bearing 4 is sleeved on the protrusion 3. Both the bearing 4 and the transducer housing 2 use the blade body 1 as the assembly reference. This can reduce the accumulation of errors generated during the assembly of the ultrasonic blade holder 100, improve the overall assembly accuracy of the ultrasonic blade holder 100, thereby reducing the processing error of the ultrasonic processing equipment 1000 and improving the processing quality of the product.

[0061] In some specific implementations, the protrusion 3 can be integrally formed with the blade body 1, or it can be understood that the protrusion 3 and the blade body 1 can be manufactured using an integral molding process. The transducer housing 2 is provided with a corresponding connecting hole 22, which is used to avoid the protrusion 3. The protrusion 3 is inserted into and fixed in the connecting hole 22, so as to achieve the technical effect that part of the structure of the protrusion 3 extends into the transducer housing 2, and to form an installation gap 31 between the blade body 1 and the transducer housing 2.

[0062] Furthermore, the outer diameter of the protrusion 3 is smaller than the diameter of the end wall edge of the first end. Further, the outer diameter of the protrusion 3 is smaller than the diameter of the end wall edge of the transducer housing 2 near the blade body 1. When the bearing 4 is sleeved on the outer periphery of the protrusion 3, reducing the outer diameter of the protrusion 3 can correspondingly reduce the diameter of the bearing 4, thereby reducing the outer diameter of the inner ring 41 and the outer ring 42 of the bearing 4. When the blade body 1 rotates at the same speed, the outer ring 42 of the bearing 4 rotates relative to the inner ring 41. Compared to a larger bearing 4 diameter, reducing the diameter of the bearing 4 can reduce the linear velocity of the outer edge of the inner ring 41, allowing the bearing 4 to operate at a relatively higher speed and reducing the frictional heat generated by the bearing 4, thus improving the service life of the ultrasonic scalpel handle 100.

[0063] In other embodiments of this application, the protrusion 3 is fixed to the end wall of the transducer housing 2 near the blade body 1 (i.e., the rear end wall of the transducer housing 2), and the end wall of the first end of the blade body 1 (i.e., the front end wall of the blade body 1) is correspondingly provided with a connecting hole 22. The protrusion 3 is inserted into and fixed in the connecting hole 22. In some specific embodiments, the protrusion 3 can be integrally formed with the transducer housing 2, or it can be understood that the protrusion 3 and the transducer housing 2 can be manufactured by an integral molding process. The blade body 1 is correspondingly provided with a connecting hole 22, which is used to avoid the protrusion 3. The protrusion 3 is inserted into and fixed in the connecting hole 22 to achieve the technical effect that part of the structure of the protrusion 3 extends into the blade body 1, and to form an installation gap 31 between the blade body 1 and the transducer housing 2.

[0064] like Figures 5-7 As shown, in some embodiments of this application, the protrusion 3 includes a first connecting section 32 and a first welding section 33 arranged axially along the protrusion 3. Both the first connecting section 32 and the first welding section 33 are located within the connecting hole 22. The first connecting section 32 is connected to and positioned within the connecting hole 22. Specifically, the inner peripheral wall of the connecting hole 22 is provided with a second connecting section 27 corresponding to the first connecting section 32, and the first connecting section 32 is connected to the second connecting section 27. By connecting the first connecting section 32 to the second connecting section 27, the technical effect of connecting the blade body 1 and the transducer housing 2 together by the protrusion 3 can be achieved. Furthermore, by positioning the first connecting section 32 with the connecting hole 22, the depth of the protrusion 3 inserted into the transducer housing 2 can be limited, thereby defining an installation gap 31 between the blade body 1 and the transducer housing 2 on the outer peripheral side of the protrusion 3.

[0065] Furthermore, the inner peripheral wall of the connecting hole 22 is provided with a second welding section 26 corresponding to the first welding section 33, and the first welding section 33 and the second welding section 26 are welded together. It should be understood that during the assembly process of the ultrasonic scalpel holder 100 of this application, the first connecting section 32 and the second connecting section 27 need to be connected together first, and then the first welding section 33 and the second welding section 26 need to be welded together to ensure that there is a good connection effect between the first connecting section 32 and the second connecting section 27, and between the first welding section 33 and the second welding section 26.

[0066] In some embodiments, when the blade body 1 is fixedly provided with a protrusion 3 and the transducer housing 2 is provided with a connecting hole 22, the first connecting segment 32 is located on the side of the first welding segment 33 near the transducer housing 2. At this time, there is a gap between the bearing 4 and the transducer housing 2, and the assembler can weld the first welding segment 33 and the second welding segment 26 together through the gap between the bearing 4 and the transducer housing 2. In the above embodiments, the connecting hole 22 may not communicate with the receiving cavity 21. In other embodiments, the connecting hole 22 communicates with the receiving cavity 21, and the first connecting segment 32 is located on the side of the first welding segment 33 near the blade body 1. By making the connecting hole 22 communicate with the receiving cavity 21, the assembler can weld the first welding segment 33 and the second welding segment 26 together from inside the receiving cavity 21, thereby reducing the welding difficulty of the first welding segment 33 and the second welding segment 26.

[0067] like Figures 5-7 As shown, in some embodiments of this application, the first connecting segment 32 includes a first threaded segment 321 and a first tapered segment 322 arranged axially along the protrusion 3, and the second connecting segment 27 is correspondingly provided with a second threaded segment 24 and a second tapered segment 25. The outer peripheral wall of the first threaded segment 321 is provided with external threads, and the inner peripheral wall of the second threaded segment 24 is provided with internal threads. The first threaded segment 321 and the second threaded segment 24 are threadedly connected. The outer peripheral wall of the first tapered segment 322 is constructed as a tapered surface. From the rear end to the front end of the ultrasonic scalpel handle 100, the cross-sectional area of ​​the tapered segment gradually decreases. The inner peripheral wall of the second tapered segment 25 is constructed as a tapered surface that matches the shape of the outer peripheral wall of the first tapered segment 322. By using the first conical section 322 and the second conical section 25 for a stop and positioning fit, the depth of the protrusion 3 inserted into the transducer housing 2 can be limited. This allows the outer side of the protrusion 3 to be reserved for the installation of the bearing 4, while preventing the transducer housing 2 from pressing against the bearing 4 and causing the bearing 4 to jam during operation. In addition, the conical surface fit between the protrusion 3 and the transducer housing 2 can improve the concentricity of the protrusion 3 relative to the transducer housing 2, thereby preventing the cutter body 1 from being eccentrically positioned with the transducer housing 2, which would increase the runout of the transducer housing 2 during rotation.

[0068] Preferably, the first tapered section 322 is located on the side of the first threaded section 321 closest to the blade body 1 (i.e., the rear side of the first threaded section 321). This design can improve the assembly accuracy of the ultrasonic scalpel handle 100. At the same time, this design can also reduce the machining difficulty of the connecting hole 22, so that the machining of the connecting hole 22 does not require the use of special-shaped tools. In addition, if the first tapered section 322 is set on the front side of the first threaded section 321, although the strength of the transducer housing 2 at the connecting hole 22 can be improved by increasing the length between the second tapered section 25 and the receiving cavity 21, it will result in a shortening of the length of the first threaded section 321, thereby reducing the connection strength between the blade body 1 and the transducer housing 2. However, by setting the first tapered section 322 on the rear side of the first threaded section 321, the length of the first threaded section 321 can be made moderate while ensuring sufficient strength at the connecting hole 22.

[0069] According to some specific embodiments of this application, the first connecting segment 32 may also include a tapered thread segment. The tapered thread segment has both a tapered surface and a threaded section. When the tapered thread segment is connected to the connecting hole 22, it can generate a greater connection strength, but the connection accuracy of the tapered thread of the tapered thread segment is poor.

[0070] like Figure 3 , Figure 5 , Figure 6 As shown, in some embodiments of this application, when the connecting hole 22 communicates with the receiving cavity 21, a first wire channel 11 is provided inside the blade body 1, and a second wire channel 34 is provided in the protrusion 3. Both the first wire channel 11 and the second wire channel 34 are used for the passage of wires between the wireless receiving unit 5 and the transducer 200. Specifically, the first wire channel 11 forms a first communication port 12 on the outer peripheral wall of the blade body 1. The first communication port 12 is disposed opposite to the receiving unit 5 and connects the first wire channel 11 and the receiving unit 5. One end of the wire is electrically connected to the receiving unit 5, and the other end can pass through the first communication port 12 into the first wire channel 11. The first wire channel 11 can extend radially into the blade body 1.

[0071] The second wire channel 34 connects the first wire channel 11 and the receiving cavity 21. The wire in the first wire channel 11 can be further inserted into the second wire channel 34 and then into the receiving cavity 21 so that the wire is electrically connected to the transducer 200. This eliminates the need to make additional holes in the transducer housing 2 to avoid the wire, which can reduce the processing difficulty of the ultrasonic scalpel handle 100.

[0072] like Figure 5 , Figure 6As shown, in some other embodiments, the protrusion 3 is further provided with a third wire channel 35. The second wire channel 34 extends axially along the protrusion 3. The third wire channel 35 is located on the side of the second wire channel 34 facing the receiving cavity 21 and is arranged on the outer periphery of the second wire channel 34. The second wire channel 34 and the receiving cavity 21 are connected through the third wire channel 35. The central axis of the third wire channel 35 forms an angle with the central axis of the second wire channel 34. The wire outlet formed on the outer surface of the protrusion 3 by the third wire channel 35 is located on the end wall or outer periphery of the protrusion 3 that extends into the receiving cavity 21, and the wire outlet is located on the outer periphery of the transducer 200. The wires in the receiving unit 5 can sequentially pass through the first wire channel 11, the second wire channel 34 and the third wire channel 35 into the receiving cavity 21. The wires can be connected to the transducer 200 from the outer periphery of the transducer 200 to reduce the difficulty of connecting the wires to the transducer 200 and to make reasonable use of the space of the receiving cavity 21 after the wires pass through it.

[0073] like Figure 1 , Figure 3 As shown, in some embodiments of this application, the ultrasonic tool holder 100 may further include: a tool changing ring 6, which is fixedly sleeved on the outer periphery of the tool body 1, installed at the front end of the wireless receiving unit 5, and located on the outer periphery of the protrusion 3. The side wall of the tool changing ring 6 away from the protrusion 3 is provided with a tool changing groove 61, that is, the outer side wall of the tool changing ring 6 is provided with a tool changing groove 61, which extends along the circumference of the protrusion 3. When the machine tool needs to process the part blank multiple times according to the processing procedure, and the tool 400 required for at least two processing steps is of different specifications, or when the ultrasonic tool holder 100 needs to be cooled after long-term operation, the machine tool can automatically change tools by setting the tool changing ring 6 on the ultrasonic tool holder 100.

[0074] When the machine tool needs a tool change, the spindle moves the ultrasonic tool holder 100 to the tool magazine. The tool changing arm clamps the ultrasonic tool holder 100 through the tool changing slot 61. The spindle releases the tool to unlock the spindle and the ultrasonic tool holder 100 to be replaced. Then, the tool changing arm rotates, sending the ultrasonic tool holder 100 back to the tool magazine and moving the ultrasonic tool holder 100 to be used to the spindle side. After the spindle grips the tool, the spindle and the ultrasonic tool holder 100 to be used are interlocked, thus completing the automatic tool changing process of the machine tool. If the tool changing ring 6 is not provided, the ultrasonic tool holder 100 can only be fixed in the tool magazine by its outer housing. When the spindle moves to face the ultrasonic tool holder 100, the spindle moves towards the ultrasonic tool holder 100, which will exert a force on the outer housing, causing the bearing 4 to be stressed and potentially damaged. The above-described automatic spindle tool changing is only one form; other tool changing methods can also be used, which will not be elaborated here.

[0075] Furthermore, such as Figure 1As shown, a positioning groove 62 can also be provided on the tool changing ring 6. The positioning groove 62 is connected to the tool changing groove 61. The groove width of the positioning groove 62 is different from that of the tool changing groove 61. A positioning structure corresponding to the positioning groove 62 can also be provided on the tool changing arm, so that the positioning structure extends into the positioning groove 62 to realize the positioning of the tool changing arm and the ultrasonic scalpel handle 100.

[0076] Furthermore, such as Figure 1 , Figure 3 As shown, along the front-rear direction of the ultrasonic scalpel handle 100, the tool changing ring 6 is installed at the front end of the receiving unit 5. When the receiving unit 5 and the transmitting unit are connected directly opposite each other, this setting can prevent the tool changing ring 6 from obstructing the connection between the receiving unit 5 and the transmitting unit, and can reduce the distance between the receiving unit 5 and the transmitting unit, thereby ensuring that the receiving unit 5 can smoothly receive the current transmitted by the transmitting unit.

[0077] Furthermore, the receiving unit 5 is fixedly connected to the tool body 1. Thus, the tool changing ring 6, the receiving unit 5, and the tool body 1 together form an integrated structure. When the tool body 1 is driven to rotate by the spindle, the tool body 1 can drive the receiving unit 5 and the tool changing ring 6 to rotate together, so that the tool changing ring 6 and the receiving unit 5 are both stationary relative to the spindle, which helps to reduce the positioning difficulty of the tool changing ring 6 and the tool changing arm.

[0078] like Figures 1-3 As shown, in some embodiments of this application, the ultrasonic scalpel handle 100 may further include: an air guide seat 7, which can be used as the outer shell of the ultrasonic scalpel handle 100. The air guide seat 7 is rotatably sleeved on the outer periphery of the protrusion 3 via a bearing 4. The bearing 4 is the bearing 4 in the above embodiment. Specifically, the bearing 4 has an outer ring 42 and an inner ring 41. The outer ring 42 of the bearing 4 can rotate relative to the inner ring 41. The air guide seat 7 is fixedly connected to the outer ring 42 of the bearing 4, and the inner ring 41 of the bearing 4 is fixedly connected to the protrusion 3, so that the air guide seat 7 can rotate relative to the scalpel body 1.

[0079] An air guide channel 71 is provided inside the air guide seat 7. An air inlet 74 is formed on the outer wall of the air guide channel 71. One end of the air guide channel 71 with the air inlet 74 is connected to an external air source, which provides a heat exchange gas medium to the air guide channel 71. It should be noted that the type of heat exchange gas medium can be set according to the type of workpiece being processed; the heat exchange gas medium can be air or other media, such as helium. The other end of the air guide channel 71 is connected to the receiving cavity 21, which is connected to the external environment. The heat exchange gas medium in the air guide channel 71 can flow into the receiving cavity 21 and exit from the receiving cavity 21 to the external environment. When the heat exchange gas medium flows through the receiving cavity 21, it exchanges heat with the transducer 200 to regulate the temperature of the transducer 200. It should be noted that a through hole can be provided on the amplitude transformer 300 to connect the receiving cavity 21 and the external environment, allowing the receiving cavity 21 to indirectly connect to the external environment through the through hole of the amplitude transformer 300.

[0080] The temperature of the heat exchange gas medium can be set according to the operating conditions of the transducer 200. When the transducer 200 is operating at high temperature, the temperature of the heat exchange gas medium can be lower than the temperature of the transducer 200. After entering the ultrasonic processing equipment 1000 through the air guide channel 71, the heat exchange gas medium can cool the transducer 200, thereby preventing the transducer 200 from overheating and being damaged. When the transducer 200 is cold-starting, the temperature of the heat exchange gas medium can be higher than the temperature of the transducer 200. After entering the ultrasonic processing equipment 1000 through the air guide channel 71, the heat exchange gas medium can heat the transducer 200, so that the transducer 200 can reach the optimal operating temperature range more quickly.

[0081] like Figure 3 , Figure 8 As shown, in some embodiments of this application, the ultrasonic scalpel holder 100 may further include: a heat exchange sleeve 8, which is sleeved on the outer periphery of the bearing 4 and sandwiched between the bearing 4 and the air guide seat 7. The air guide seat 7 is fixedly connected to the outer ring 42 of the bearing 4 through the heat exchange sleeve 8. In some preferred embodiments, such as Figure 8 , Figure 9 As shown, the outer peripheral wall of the front end of the heat exchange bushing 8 is provided with an external thread 85, and the inner peripheral wall of the air guide seat 7 is provided with an internal thread accordingly. The heat exchange bushing 8 and the air guide seat 7 are connected by threads.

[0082] A heat exchange channel 81 is provided on the heat exchange sleeve 8, which is connected to the air guide channel 71 and to the external environment. In some embodiments, the air guide seat 7 or other outer shells of the ultrasonic scalpel handle 100 are provided with air passages connecting the heat exchange channel 81 and the external environment to achieve the technical effect of connecting the heat exchange channel 81 to the external environment. In other embodiments, the heat exchange channel 81 is connected to the receiving cavity 21, and thus the heat exchange channel 81 is indirectly connected to the external environment through the receiving cavity 21. After the heat exchange gas medium flows into the heat exchange channel 81 from the air guide channel 71, the heat exchange gas medium can exchange heat with the bearing 4 through the heat exchange sleeve 8. For example, the heat exchange gas medium can cool the bearing 4. When the inner ring 41 of the bearing 4 rotates relative to the outer ring 42 and generates a large amount of frictional heat, the heat exchange gas medium cooling the bearing 4 can prevent the bearing 4 from overheating, thereby slowing down the wear rate of the bearing 4 and improving the working reliability of the ultrasonic processing equipment 1000.

[0083] Furthermore, the heat exchange sleeve 8 is located inside the tool changing ring 6. Compared to placing the heat exchange sleeve 8 at the front or rear end of the tool changing ring 6, this arrangement ensures good heat exchange for the bearing 4 while preventing the heat exchange sleeve 8 from affecting the tool changing process of the tool changing ring 6. It also eliminates the need for additional axial length extension of the ultrasonic scalpel holder 100. Moreover, a gap exists between the tool changing ring 6 and the heat exchange sleeve 8. When the tool changing ring 6 rotates relative to the heat exchange sleeve 8, this gap reduces friction between them, further preventing the heat exchange sleeve 8 from interfering with the normal tool changing process of the tool changing ring 6.

[0084] Furthermore, such as Figure 8 As shown, the heat exchange bushing 8 includes a bushing body 86 and an airflow shroud 87. The airflow shroud 87 is sleeved on the outside of the bushing body 86. The heat exchange channel 81 includes at least an air inlet channel 811 and an exhaust channel 812 that are interconnected. The air inlet channel 811 can be formed by providing an air inlet groove 8111 that is recessed radially inward along the outer peripheral wall of the bushing body 86. The exhaust channel 812 can be formed by providing an exhaust groove 8121 that is recessed radially inward along the outer peripheral wall of the bushing body 86. The airflow shroud 87 located on the outer peripheral side of the bushing body 86 is used to cover the air inlet groove 8111 and the exhaust groove 8121 to form the air inlet channel 811 and the exhaust channel 812.

[0085] The air intake end of the air intake channel 811 is connected to the air guide channel 71, and the other end of the air intake channel 811 extends toward the blade body 1. In other words, the air intake channel 811 extends along the front and rear direction of the ultrasonic blade handle 100 to guide the airflow toward the blade body 1. The air intake channel 811 can make the heat exchange gas medium flow from the front end to the rear end of the bearing 4.

[0086] The exhaust end of the exhaust channel 812 is connected to the receiving cavity 21, and the other end of the exhaust channel 812 is connected to the inlet channel 811. Preferably, the exhaust channel 812 extends along the front-rear direction of the ultrasonic scalpel handle 100, and the exhaust channel 812 and the inlet channel 811 are spaced apart along the circumference of the bearing 4. The exhaust channel 812 allows the heat exchange gas medium to flow from the rear end to the front end of the bearing 4. By cooperating with the inlet channel 811 and the exhaust channel 812, a more uniform temperature can be ensured between the front and rear ends of the bearing 4.

[0087] In some other embodiments, the intake end of the intake channel 811 is connected to the air guide channel 71, and the other end of the intake channel 811 extends toward the receiving cavity 21 to guide the airflow toward the receiving cavity 21. The exhaust end of the exhaust channel 812 is connected to the receiving cavity 21, and the other end of the exhaust channel 812 is connected to the intake channel 811. The heat exchange gas medium in the air guide channel 71 can flow sequentially through the intake channel 811 and the exhaust channel 812 before flowing into the receiving cavity 21, thereby achieving the technical effect of connecting the air guide channel 71 and the receiving cavity 21.

[0088] like Figure 9 As shown, in some embodiments of this application, there are multiple intake channels 811 and exhaust channels 812, and each intake channel 811 and each exhaust channel 812 are arranged at intervals along the circumference of the heat exchange sleeve 8. By setting multiple sets of heat exchange channels 81, the outer space of the heat exchange sleeve 8 can be utilized as much as possible, and the heat exchange area on the outer side of the bearing 4 can be increased, which helps to quickly adjust the working temperature of the bearing 4.

[0089] In the longitudinal direction of the ultrasonic scalpel holder 100, the inlet end of each air inlet channel 811 and the exhaust end of each exhaust channel 812 are located close to the front end of the heat exchange sleeve 8. The rear end of the heat exchange sleeve 8 is provided with an annular first connecting channel 82, which connects each air inlet channel 811 and each exhaust channel 812. The heat exchange gas medium flowing through the multiple air inlet channels 811 can all flow into the first connecting channel 82, where it mixes and is then diverted again into the multiple exhaust channels 812, thereby further improving the temperature uniformity of the heat exchange gas medium in the multiple exhaust channels 812.

[0090] like Figure 8 , Figure 9 As shown, in some embodiments of this application, along the circumference of the heat exchange sleeve 8, an exhaust channel 812 is provided between any two adjacent air inlet channels 811, and an air inlet channel 811 is provided between any two adjacent exhaust channels 812. By arranging the air inlet channels 811 and exhaust channels 812 alternately on the heat exchange sleeve 8, the air inlet channels 811 and exhaust channels 812 can be evenly distributed on the outer peripheral wall of the heat exchange sleeve 8. This arrangement helps to further improve the heat exchange uniformity at various points on the heat exchange sleeve 8.

[0091] like Figure 10 As shown, the air guide seat 7 has an air inlet ring 72 surrounding the outer periphery of the heat exchange sleeve 8. The inner peripheral wall of the air inlet ring 72 forms a second connecting channel 73 around the heat exchange sleeve 8. The second connecting channel 73 connects the air guide channel 71 and multiple air inlet channels 811. The heat exchange gas medium in the air guide channel 71 can be diverted to the multiple air inlet channels 811 through the second connecting channel 73, so that there is no need to connect the multiple air inlet channels 811 to the air guide channel 71 one by one, which can make the structure of the ultrasonic scalpel holder 100 simpler and more compact.

[0092] It should be noted that, as Figure 8 As shown, to ensure that the second connecting channel 73 does not directly supply heat exchange gas medium to the exhaust channel 812, the inlet channel 811 and the exhaust channel 812 are spaced apart, and the front end of the inlet channel 811 is located in front of the front end of the exhaust channel 812. The airflow shroud 87 covers the rear end of the inlet groove 8111 and the exhaust groove 8121, blocking the communication between the second connecting channel 73 and the exhaust channel 812, and does not cover the front end of the inlet groove 8111, so that the second connecting channel 73 is only connected to the inlet end of the inlet channel 811, thereby restricting the direct supply of gas from the second connecting channel 73 to the exhaust channel 812. Moreover, the exhaust end of the exhaust channel 812 penetrates the inner wall of the bushing body 86 to form an exhaust hole 84, which communicates with the receiving cavity 21.

[0093] like Figure 3 As shown, in some embodiments of this application, the heat exchange sleeve 8 extends along the front-rear direction of the ultrasonic scalpel handle 100 to the outer periphery of the transducer housing 2. The portion of the heat exchange sleeve 8 fitted onto the outer periphery of the transducer housing 2 forms an annular connecting cavity 83 with the transducer housing 2. Each exhaust channel 812 has an exhaust hole 84 at its exhaust end, which is opposite to and connected to the connecting cavity 83. The portion of the transducer housing 2 that forms the connecting cavity 21 has an air passage 23, which connects the connecting cavity 83 and the receiving cavity 21. When the heat exchange gas medium exchanges heat with the bearing 4 in the heat exchange channel 81, the heat exchange gas medium in each exhaust channel 812 can first flow to the connecting cavity 83 through the exhaust hole 84. The heat exchange gas medium is mixed in the connecting cavity 83, and then flows into the receiving cavity 21 through the air passage 23 to exchange heat with the transducer 200, thereby achieving the technical effect of regulating the operating temperature of the transducer 200.

[0094] In some preferred embodiments, such as Figure 3 , Figure 7As shown, the outer peripheral wall of the transducer housing 2 can be provided with multiple air passages 23, which are arranged sequentially along the circumference of the transducer housing 2. This allows the heat exchange gas medium to flow into the transducer housing 2 from multiple directions, improving the temperature uniformity of the transducer 200. Furthermore, the connecting cavity 83 allows the heat exchange gas medium to be evenly distributed to the multiple air passages 23, ensuring that the flow rate of the heat exchange gas medium into the transducer housing 2 from each air passage 23 is basically the same, thereby making the temperature more uniform throughout the transducer 200.

[0095] According to some specific embodiments of this application, the heat exchange sleeve 8 may also be provided with a venting channel. The venting channel is connected to the external environment and is used to discharge the heat exchange gas medium leaked from various channels (such as heat exchange channel 81, connecting cavity 83, etc.) in the ultrasonic scalpel handle 100, thereby preventing the leaked heat exchange gas medium from affecting the gas pressure in the ultrasonic scalpel handle 100, and thus reducing the impact of gas pressure changes in the ultrasonic scalpel handle 100 on the operational stability of the scalpel body 1.

[0096] Based on this, this application further discloses an ultrasonic processing device 1000, which, according to an embodiment of this application, includes the ultrasonic tool holder 100 of the above embodiment. Figure 1 In the embodiment shown, the ultrasonic processing equipment 1000 can use a cutting tool 400 to process a hole structure on a part blank.

[0097] Based on the aforementioned ultrasonic processing equipment 1000, this embodiment also provides a machine tool, including a machine tool body, a spindle, and the ultrasonic processing equipment 1000 of the above embodiment. The spindle is mounted on the machine tool body, and the machine tool body is used to drive the spindle to rotate around the central axis of the spindle. The ultrasonic tool holder 100 of the ultrasonic processing equipment 1000 is connected to the spindle.

[0098] In summary, the ultrasonic scalpel holder 100 provided in this application has the following advantages:

[0099] 1. By providing a protrusion 3 between the transducer housing 2 and the blade 1, the protrusion 3 can be inserted into the blade 1 or the transducer housing 2 to achieve the connection between the blade 1 and the transducer housing 2. Compared with the prior art, in the case of limited radial space inside the ultrasonic scalpel handle 100, mainly to reduce bearing heat generation, when the protrusion 3 is set as one, the wall thickness of a single protrusion 3 is larger, which can improve the strength of the connection between the blade 1 and the transducer housing 2. It can prevent the connection between the two from breaking when the blade 1 drives the transducer housing 2 to rotate at high speed, thereby improving the working reliability of the ultrasonic scalpel handle 100 and thus improving the product quality of the ultrasonic processing equipment 1000.

[0100] 2. By setting a first wire channel 11 in the blade body 1 and a second wire channel 34 in the protrusion 3, and connecting the connection hole 22 to the receiving cavity 21, one end of the wire is electrically connected to the receiving unit 5, and the other end passes through the first wire channel 11 and the second wire channel 34 in sequence and extends into the receiving cavity 21, so that the other end of the wire is electrically connected to the transducer 200. Compared with the prior art, there is no need to open additional holes on the transducer housing 2 to avoid the wire, which can reduce the processing difficulty of the ultrasonic scalpel handle 100.

[0101] 3. The heat exchange bushing 8 is located inside the tool changing ring 6. Compared with setting the heat exchange bushing 8 at the front or rear end of the tool changing ring 6, this setting can avoid the heat exchange bushing 8 affecting the tool changing process of the tool changing ring 6 while ensuring that the heat exchange bushing 8 has a good heat exchange effect on the bearing 4. It can also make the axial length of the ultrasonic scalpel handle 100 not need to be extended, making the ultrasonic scalpel handle 100 structure compact.

[0102] The above description is only a preferred embodiment of this application. 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 this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
