[0028] Please refer to the following: Figures 1 to 6 The ultrasonic lathe tool clamping device provided in the embodiments of this utility model will now be described.

[0029] like Figures 1 to 4As shown in the figure, the ultrasonic lathe tool clamping device of this utility model is used to clamp an ultrasonic lathe tool 300, and includes: a fixed base 100 and a tool disc 200; the tool disc 200 is rotatably connected to the fixed base 100, and a tool holder 210 for mounting the ultrasonic lathe tool 300 is provided on the outer peripheral surface of the tool disc 200; the tool holder 210 is provided with a power supply unit 220 for electrically connecting to the ultrasonic lathe tool 300, and the fixed base 100 is provided with a power supply unit 110 and a drive unit 120. The driving unit 120 is connected to the power supply unit 110, and the driving unit 120 is used to drive the power supply unit 110 to move back and forth along a first direction, so that the power supply unit 110 moves back and forth between an engaged position and a disengaged position; when the power supply unit 110 is in the engaged position, the power supply unit 110 is electrically connected to the power consumption unit 220; when the power supply unit 110 is in the disengaged position, the power supply unit 110 is electrically disconnected from the power consumption unit 220.

[0030] Drive unit 120 is a linear drive device, with the first direction being... Figure 1 In the X direction, the drive unit 120 can drive the power supply unit 110 to move back and forth in the X direction, that is, to move back and forth between the power supply unit and the power consumption unit, so that the power supply unit 110 is in contact with the power consumption unit 220 in the engagement position and disconnected from the power consumption unit 220 in the disengagement position.

[0031] The fixed base 100 is rotatably connected to the tool head 200. The tool head 200 is provided with a cutting tool holder 210, that is, the tool head 200 can rotate around its rotation axis, so that the cutting tool holder 210 can rotate, so that the machine tool can automatically change tools.

[0032] The power supply unit 110 is electrically connected to the ultrasonic generator via a wire, meaning the ultrasonic generator can provide power to the power supply unit 110. Since the cutter head 200 can rotate relative to the fixed base 100, when the ultrasonic cutting tool needs to be replaced, the drive unit 120 drives the power supply unit 110 to move to the separation position, so that the power supply unit 110 and the power consumption unit 220 are separated. Then the cutter head 200 rotates relative to the fixed base 100, driving the cutting tool holder 210 to rotate, so that the ultrasonic cutting tool to be replaced is close to the spare tool magazine, which facilitates automatic tool replacement. After tool change, the tool head 200 rotates so that the power supply unit 220 on the tool holder 210 aligns with the power supply unit 110 on the fixed base 100. At this time, the fixed base 100 and the tool head 200 are relatively fixed. The power supply unit 110 can be driven to the engagement position by the drive unit 120. The power supply unit 110 and the power supply unit 220 are electrically connected. The ultrasonic generator is then electrically connected to the ultrasonic turning tool 300 through the power supply unit 110 and the power supply unit 220, providing power to the ultrasonic turning tool 300 so that the ultrasonic turning tool 300 can perform ultrasonic turning on the workpiece. Since the power supply unit 110 and the power supply unit 220 are directly in contact to achieve electrical connection, that is, the ultrasonic turning tool 300 and the ultrasonic generator are wired at this time. Compared with ultrasonic turning equipment that transmits power wirelessly, the ultrasonic turning tool clamping device in this embodiment has higher power transmission efficiency and can provide sufficient power to the ultrasonic turning tool 300. The ultrasonic turning tool 300 can improve processing efficiency and reduce energy loss, thus saving energy.

[0033] In this embodiment, the ultrasonic turning tool clamping device uses the drive unit 120 to drive the power supply unit 110 to move back and forth between the engagement position and the disengagement position. When the power supply unit 110 is in the engagement position, the fixed seat 100 and the tool disc 200 are relatively fixed, and the power supply unit 110 is electrically connected to the power consumption unit 220. Then, the ultrasonic generator is electrically connected to the ultrasonic turning tool 300 through the power supply unit 110 and the power consumption unit 220, providing power to the ultrasonic turning tool 300, so that the ultrasonic turning tool 300 can perform ultrasonic turning on the workpiece. That is, at this time, the ultrasonic turning tool 300 and the ultrasonic generator are wired together. Secondly, the power transmission efficiency is higher than that of ultrasonic turning equipment that transmits power wirelessly, providing sufficient power to the ultrasonic turning tool 300. Therefore, the ultrasonic turning tool 300 can improve processing efficiency and reduce energy loss, saving energy. Thirdly, when the power supply unit 110 is in the separated position, the power supply unit 110 and the power consumption unit 220 are separated, that is, the tool holder 210 is separated from the fixed seat 100. The tool disc 200 can rotate relative to the fixed seat 100 at this time, which can drive the tool holder 210 to rotate, facilitating automatic tool changing and solving the problem that wired ultrasonic turning equipment cannot automatically change tools.

[0034] It is understood that the drive unit 120 can be a linear drive device such as a cylinder or hydraulic cylinder. In this embodiment, the drive unit 120 is a cylinder, and the moving end of the cylinder is connected to the power supply unit 110 so that the cylinder drives the power supply unit 110 to move back and forth.

[0035] In some embodiments of this utility model, reference is made to Figures 3 to 5 The power supply unit 220 includes a first mounting base 221 and a power terminal 222; the first mounting base 221 is provided with a first receiving cavity 223, and the power terminal 222 is disposed in the first receiving cavity 223; the first receiving cavity 223 is provided with a first opening 224; the power supply unit 110 is provided with a second mounting base 111 and a power terminal 112; the power terminal 112 is disposed on the second mounting base 111; when the power supply unit 110 is in the engaged position, the first opening 224 faces the second mounting base 111, and the second mounting base 111 extends into the second mounting base 111 from the first opening 224. Within the first receiving cavity 223, the power supply terminal 112 contacts the power consumption terminal 222, so that the power supply unit 110 is electrically connected to the power consumption unit 220. That is, when the ultrasonic lathe tool 300 needs power, the tool disc 200 drives the tool holder 210 to rotate, so that the first opening 224 of the power consumption unit 220 is aligned with the second mounting base 111, so that the drive unit 120 drives the second mounting base 111 of the power supply unit 110 to extend into the first receiving cavity 223, so that the power supply terminal 112 and the power consumption terminal 222 are in contact, which facilitates the electrical connection between the ultrasonic generator and the ultrasonic lathe tool 300, and provides sufficient power to the ultrasonic lathe tool 300.

[0036] In some embodiments of this utility model, reference is made to Figures 3 to 5The second mounting base 111 is provided with a second receiving cavity 113, the second receiving cavity 113 is provided with a second opening 114, and the second mounting base 111 is provided with a gas inlet 115 communicating with the second receiving cavity 113; the first mounting base 221 is provided with a gas outlet 225 communicating with the first receiving cavity 223; when the power supply unit 110 is in the engaged position, the second opening 114 faces the first mounting base 221, and the second mounting base 111 extends into the first receiving cavity 223 from the first opening 224. Furthermore, the second mounting base 111 seals the first opening 224, and the second receiving cavity 113 communicates with the first receiving cavity 223 through the second opening 114, thus preventing external cutting fluid from entering the first receiving cavity 223 or the second receiving cavity 113. Moreover, the gas inlet 115 is connected to a high-pressure gas source to allow the introduction of high-pressure gas. The high-pressure gas can discharge the cutting fluid located in the first receiving cavity 223 and the second receiving cavity 113 from the gas outlet 225, keeping the first receiving cavity 223 and the second receiving cavity 113 dry and preventing leakage. In addition, introducing high-pressure gas into the first receiving cavity 223 and the second receiving cavity 113 can also remove impurities from the first receiving cavity 223 and the second receiving cavity 113, ensuring good contact between the power supply terminal 112 and the power consumption terminal 222.

[0037] Understandably, in order to ensure sealing performance, the outer side of the second mounting base 111 is provided with a sealing groove 118 for installing a sealing strip, so that when the second mounting base 111 extends into the first receiving cavity 223, it seals the gap between the first mounting base 221 and the second mounting base 111, preventing cutting fluid from seeping into the first receiving cavity 223 from the gap between the first mounting base 221 and the second mounting base 111, and also preventing high-pressure gas from leaking from the gap between the first mounting base 221 and the second mounting base 111, thus ensuring the cutting fluid removal effect.

[0038] In some embodiments of this utility model, reference is made to Figures 3 to 5The first mounting base 221 is provided with an inclined surface 226 located within the first receiving cavity 223. The inclined surface 226 gradually expands outward toward the first opening 224, i.e., the cross-sectional area gradually increases as it expands outward. The gas outlet 225 is located on the inclined surface 226, on the side away from the first opening 224. The first mounting base 221 is also provided with an exhaust channel 227, which communicates with the gas outlet 225. The first mounting base 221 is also provided with a first assembly 228. The first assembly 228 is located in the first receiving cavity 223 and is connected to the side of the inclined surface 226 away from the first opening 224. The power terminal 222 is located on the first assembly 228. The inclined surface 226 can guide the cutting fluid to flow to the gas outlet 225 so that the cutting fluid can be discharged to the outside through the exhaust channel 227 to prevent leakage. The first component 228 is for mounting the power terminal 222. After the first component 228 and the power terminal 222 are manufactured, they are installed in the first receiving cavity 223 for easy installation. Secondly, the first component 228 is connected to the side of the inclined surface 226 away from the first opening 224, so that the cutting fluid can be better discharged from the gas outlet 225 and the cutting fluid is prevented from accumulating at the power terminal 222.

[0039] In some embodiments of this utility model, reference is made to Figures 3 to 5 The first mounting base 221 is provided with a stepped surface 229 located within the first receiving cavity 223. The stepped surface 229 is connected to the side of the inclined surface 226 near the first opening 224, and the stepped surface 229 is used to abut against the second mounting base 111. The stepped surface 229 is used to limit the displacement of the second mounting base 111 of the power supply unit 110 to prevent excessive compression of the power supply terminal 112 and the power consumption terminal 222, thus avoiding damage.

[0040] In some embodiments of this utility model, reference is made to Figures 3 to 5 The second mounting base 111 is provided with a second component 116 located within the second receiving cavity 113. The power supply terminal 112 is installed on the side of the second component 116 facing the power supply unit 220. The second component 116 is provided with an air passage 117. The second component 116 is interference-fitted with the second receiving cavity 113, so that the second receiving cavity 113 is connected to the second opening 114 through the air passage 117. Therefore, when the power supply unit 110 is in the engaged position, the second mounting base 111 seals the first opening 224. The gas inlet 115 is connected to the gas outlet 225 in sequence through the second receiving cavity 113, the air passage 117, the second opening 114, and the first receiving cavity 223, ensuring that high-pressure gas can enter the first receiving cavity 223 to discharge the cutting fluid.

[0041] Understandably, the gas inlet 115 can be connected to a high-pressure gas source via a plastic gas tube. The first mounting base 221, the second mounting base 111, the second kit 116, and the first kit 228 can all be made of insulating and corrosion-resistant plastic.

[0042] Reference Figure 1 , Figure 2 , Figure 6 This embodiment also provides a machine tool, comprising: an ultrasonic lathe tool 300 and an ultrasonic lathe tool clamping device as described above; the tool holder 210 is provided with a mounting cavity 211, the ultrasonic lathe tool 300 includes an ultrasonic unit 310 and a cutting head 320, the ultrasonic unit 310 includes a transducer 311 and an amplitude transformer 312, the amplitude transformer 312 is fixedly connected to the transducer 311, the transducer 311 is disposed in the mounting cavity 211, the amplitude transformer 312 is fixedly connected to the tool holder 210 and the amplitude transformer 312 covers the mounting cavity 211, one end of the amplitude transformer 312 away from the transducer 311 can be connected to the cutting head 320, the cutting head 320 is located outside the mounting cavity 211. The transducer 311 is used to receive high-frequency electrical energy signals from the ultrasonic generator to convert them into high-frequency vibrations of the cutting head 320, so that the ultrasonic lathe tool 300 can perform high-frequency vibration cutting. When the power supply unit 110 of the ultrasonic turning tool clamping device is in the engaged position, the fixed base 100 and the tool disc 200 are relatively fixed, and the power supply unit 110 is electrically connected to the power consumption unit 220. The ultrasonic generator is then electrically connected to the ultrasonic turning tool 300 through the power supply unit 110 and the power consumption unit 220, providing power to the ultrasonic turning tool 300. This allows the ultrasonic turning tool 300 to perform ultrasonic turning on the workpiece. In this case, the ultrasonic turning tool 300 and the ultrasonic generator are connected via a wired connection, which significantly improves power transmission efficiency compared to wireless power transmission in ultrasonic technology. The higher turning equipment provides sufficient power to the ultrasonic turning tool 300, thus improving machining efficiency and reducing energy consumption, saving energy. Secondly, when the power supply unit 110 is in the separated position, the power supply unit 110 and the power consumption unit 220 are separated, that is, the tool holder 210 is separated from the fixed seat 100. The tool disc 200 can rotate relative to the fixed seat 100 at this time, which can drive the tool holder 210 to rotate, facilitating automatic tool changing and solving the problem that wired ultrasonic turning equipment cannot automatically change tools.

[0043] In some embodiments of this utility model, the extending direction of the mounting cavity 211 is parallel or perpendicular to the axial direction of the cutter head 200. The axial direction of the cutter head 200 is the second direction, i.e., the Y direction in the figure, as shown. Figures 1 to 4As shown, the extending direction of the mounting cavity 211 is parallel to the axial direction of the cutter head 200, which is used to determine the orientation of the entire ultrasonic lathe tool 300 for machining. Alternatively, in some embodiments, the extending direction of the mounting cavity 211 is perpendicular to the axial direction of the cutter head 200.

[0044] In some embodiments of this utility model, the cutter head 320 is detachably connected to the amplitude transformer 312 for easy replacement. A cutting insert 322 can be installed at the front end of the cutter head 320.

[0045] In some embodiments of this utility model, reference is made to Figure 6 To facilitate the replacement of the cutter head 320, the cutter head 320 is provided with an axial mounting hole 321. The extending direction of the axial mounting hole 321 is parallel to the extending direction of the mounting cavity 211. The cutter head 320 is detachably connected to the amplitude transformer 312 by a fastener 330 extending into the axial mounting hole 321. The fastener 330 can be a bolt, which facilitates the installation and removal of the cutter head 320 for convenient use.
