[0037] See Figures 1-3As shown, this utility model provides an ultrasonic CNC turning device 100, including a tool holder body 1 and a tool turret 2 mounted on a lathe housing 200. The tool turret 2 is capable of partial rotational movement relative to the tool holder body 1. The lathe housing 200 of this utility model is used to install and support the tool holder body 1 and the tool turret 2. It is a conventional housing structure and will not be described in detail here.

[0038] Multiple tool holders are provided on the circumferential side of the tool holder body 1. The tool holders include ultrasonic tool holder 11, or ultrasonic tool holder 11 and ordinary tool holder 12. Multiple power receiving modules 13 are also provided on the tool holder body 1. The power receiving modules 13 are correspondingly arranged with the ultrasonic tool holder 11 and are located on the side of the ultrasonic tool holder 11 close to the turret 2.

[0039] The turret 2 is equipped with a power supply module 21, and the power supply module 21 and the power receiving module 13 are set up accordingly. The power supply module 21 and the power receiving module 13 realize wireless power transmission.

[0040] Specifically, depending on the actual processing requirements, the tool holders provided on the tool holder body 1 can all be ultrasonic tool holders 11, or multiple ultrasonic tool holders 11 and ordinary tool holders 12 can be provided simultaneously. The number of ultrasonic tool holders 11 and ordinary tool holders 12 can be set according to actual needs. Multiple ultrasonic tool holders 11 and ordinary tool holders 12 can be arranged alternately, and multiple ultrasonic tool holders 11 and ordinary tool holders 12 can also be combined according to processing requirements. For example, for processing the end face of the workpiece, the outer circle of the workpiece, and the inner hole of the workpiece, the corresponding ultrasonic tool holders 11 and ordinary tool holders 12 can be selected respectively. That is, both ultrasonic tool holders 11 and ordinary tool holders 12 can be detachably installed with the tool holder body 1, which is convenient for disassembly and assembly when replacing, and can realize the simultaneous use of ultrasonic tool holders and ordinary tool holders, thereby improving the working efficiency of the device.

[0041] For further details, please refer to [link / reference]. Figure 3 and Figure 4 As shown, the turret 2 includes a turret base 22 and a mounting part 23. The mounting part 23 is rotatable relative to the turret base 22. The mounting part 23 is provided with multiple mating grooves 231, which are respectively positioned and engaged with the tool holders (ultrasonic tool holder 11 and ordinary tool holder 12). The mounting part 23 drives the ultrasonic tool holder 11, the ordinary tool holder 12, and the power receiving module 13 to rotate. Understandably, the mounting part 23 can be driven by a power mechanism such as a motor to achieve the rotational movement.

[0042] The power supply module 21 is set on the turret base 22 and can correspond to different power receiving modules 13 and be gap-fitted to realize wireless energy transmission, thereby driving different ultrasonic tool holders 11 to realize ultrasonic vibration processing, thus meeting different processing needs.

[0043] Specifically, the power supply module 21 is mounted on the turret base 22 via the power supply bracket 24, which facilitates installation and allows the power supply module 21 and the power receiving module 13 to work together.

[0044] See Figure 5 As shown, the power supply bracket 24 includes a base plate 241, an adjusting block 242, and a pad 243. The base plate 241 is mounted on the outer wall of the turret base 22, and the adjusting block 242 is mounted on the base plate 241. The pad 243 is mounted on the adjusting block 242, and a power supply module 21 is mounted on the pad 243 to facilitate adjustment of the installation position of the power supply module 21. The adjusting block 242 is also provided with an adjusting hole 2421. The adjusting block 242 is installed in conjunction with the base plate 241 and the pad 243 through the adjusting hole 2421, which allows adjustment of the installation position of the adjusting block 242 on the base plate 241 and the pad 243 on the adjusting block 242, thereby adjusting the height of the power supply module 21 and adjusting the gap between the power supply module 21 and the power receiving module 13 to ensure reliable wireless power transmission.

[0045] Understandably, the power supply bracket 24 can also be an integrated bracket, that is, the base plate 241, the adjusting block 242 and the pad block 243 are an L-shaped plate integrated structure. One end of the power supply bracket 24 is set on the turret base 22, and the other end is set on the power supply module 21. The integrated structure is simple and convenient for installation and coordination.

[0046] For details, please refer to Figure 6 As shown, the power supply module 21 and the power receiving module 13 each include a mounting housing 211, a mounting frame 212, and a coil 213. The mounting housing 211 contains the mounting frame 212, and the mounting frame 212 is equipped with the coil 213. The positions of the coils 213 in the power supply module 21 and the power receiving module 13 correspond to each other, realizing wireless energy transmission.

[0047] For further details, please refer to [link / reference]. Figure 7 and Figure 8 As shown, the ultrasonic scalpel holder 11 includes a holder housing 10, an amplitude transformer 20, and a tool head 30. The holder housing 10 has a receiving cavity 101. One end of the amplitude transformer 20 is provided with a transducer unit 40, which is located in the receiving cavity 101 of the holder housing 10. The transducer unit 40 is connected to the coil 213 in the power receiving module 13. The end face of the other end of the amplitude transformer 20 engages with the end face of the tool head 30, so that the tool head 30 can be detachably installed. A positioning shaft 50 is provided on the end face of the holder housing 10 away from the tool head 30. The holder housing 10 is mounted on the holder body 1. The positioning shaft 50 is engaged with the mating groove 231 of the mounting part 23 on the turret 2, so as to achieve reliable installation of the ultrasonic scalpel holder 11.

[0048] Specifically, the amplitude transformer 20 and the tool head 30 are detachably installed by meshing, which improves the stability and reliability of the connection between the two. The end of the tool head 30 is equipped with a machining tool, which makes it convenient to replace different tool heads 30 and machining tools according to different material processing requirements, thus ensuring the reliability of ultrasonic cutting processing.

[0049] Furthermore, each of the tool holders (ultrasonic tool holder 11 and ordinary tool holder 12) is provided with a positioning shaft, which is fitted with the mating groove 231 of the mounting part 23. A first positioning shaft 50 is provided on the tool holder housing 10, and a second positioning shaft 121 is provided on the ordinary tool holder 12, which facilitates mating and installation, thereby improving the stability of the installation of the ultrasonic tool holder 11 and the ordinary tool holder 12.

[0050] In one embodiment, the outer periphery of the amplitude rod 20 extends radially to form a connecting protrusion 201, which is connected to the end face of the tool holder housing 10. The connecting protrusion 201 is set as the vibration zero point.

[0051] To improve the stability of the installation of the amplitude transformer 20 and the tool holder housing 10, and to reduce the installation thickness of the connecting protrusion 201, a groove 202 is provided on the connecting protrusion 201 to form a connecting flange 203. The connecting flange 203 is connected to the tool holder housing 10, and the connecting flange 203 is set as the vibration zero point, ensuring reliable installation and reliable ultrasonic energy transmission, and improving the efficiency of ultrasonic energy transmission to the tool head 30. Understandably, bolts or other fasteners can be used between the connecting flange 203 and the tool holder housing 10, or welding can be used for fixing, both of which can reliably achieve the installation and fit between the connecting flange 203 and the tool holder housing 10.

[0052] In one embodiment, see Figure 9 As shown, the end of the tool holder housing 10 near the positioning shaft 50 is provided with multiple positioning recesses, each with a locking hole 102, which facilitates the mating and installation of the tool holder housing 10 and the tool holder body 1, makes disassembly easier, and improves the stability of the ultrasonic tool holder 11 installation. A positioning block 51 is also provided on the end face of the tool holder housing 10, located on one side of the positioning shaft 50, further improving the reliability of the installation between the tool holder housing 10 and the tool holder body 1.

[0053] Understandably, the axes of the positioning block 51 and the locking hole 102 are parallel to the axis of the positioning shaft 50, facilitating installation and disassembly. The ultrasonic scalpel holder 11 is positioned and engaged with the mating groove 231 on the scalpel holder body 1 via the positioning shaft 50 and the positioning block 51, and is fixed to the scalpel holder body 1 via the locking hole 102 using a locking element, further improving the installation reliability of the ultrasonic scalpel holder 11.

[0054] In one embodiment, a power supply head 60 is provided on the side of the tool holder housing 10, and the receiving module 13 is connected to the transducer unit 40 through the power supply head 60. The coil 213 of the power supply module 21 is connected to an external ultrasonic power supply. The ultrasonic power supply provides ultrasonic energy to the coil 213 of the power supply module 21, which generates a magnetic field effect that acts on the coil 213 of the receiving module 13, realizing wireless transmission of ultrasonic energy between the power supply module 21 and the receiving module 13. The receiving module 13 transmits energy to the piezoelectric ceramic unit inside the transducer unit 40, where the piezoelectric ceramic unit converts electrical energy into mechanical energy, driving the amplitude transformer 20 to perform ultrasonic vibration. The ultrasonic vibration is transmitted along the axial direction of the amplitude transformer 20 to the tool head 30, driving the tool head 30 to perform ultrasonic vibration processing. The connecting flange 203 is set as the vibration zero point to avoid energy loss caused by the transmission of ultrasonic vibration to the tool holder housing 10.

[0055] In one embodiment, the amplitude rod 20 and the tool head 30 are engaged by a comb-tooth structure, which enables the tool head 30 to be detachably installed and improves the stability of the connection between the amplitude rod 20 and the tool head 30.

[0056] Specifically, the end face of the amplitude transformer 20 has multiple radially parallel comb-tooth recesses (not shown in the figure), and the end face of the tool head 30 has multiple radially parallel comb-tooth protrusions 31. The comb-tooth recesses and comb-tooth protrusions 31 mesh with each other, preventing the tool head 30 from shifting its installation position when the amplitude transformer 20 drives the tool head 30 to perform ultrasonic vibration under the action of the piezoelectric ceramic unit 40. This improves the installation stability of the tool head 30 and ensures the efficiency of ultrasonic energy transmission from the amplitude transformer 20 to the tool head 30. Similarly, the end face of the amplitude transformer 20 can also have multiple radially parallel comb-tooth protrusions, and the end face of the tool head 30 can have multiple comb-tooth recesses that mesh with the comb-tooth protrusions on the amplitude transformer 20. This also allows the amplitude transformer 20 and the tool head 30 to mesh, enabling the tool head 30 to be detachably installed.

[0057] In one embodiment, see Figure 10 As shown, the tool head 30 includes a base 32 and a mounting protrusion 33. One end face of the base 32 is provided with a comb tooth protrusion 31 or a comb tooth recess, which is installed and engaged with the amplitude transformer 20. The mounting protrusion 33 extends axially on the other end face of the base 32, and a cutting blade 34 is detachably mounted on the mounting protrusion 33. The tip of the cutting blade 34 acts on the workpiece to perform machining.

[0058] Specifically, depending on the different processing conditions, such as machining the end face and outer diameter of a workpiece, machining the inner diameter of a workpiece, or cutting off a workpiece, different tool heads 30 can be changed. In this embodiment, the ultrasonic tool holder 11 includes multiple first ultrasonic tool holders 111, second ultrasonic tool holders 112, and third ultrasonic tool holders 113. Figure 3As shown in the diagram, the first ultrasonic tool holder 111 is used to process the end face and outer diameter of the workpiece, the second ultrasonic tool holder 112 is used to cut off the workpiece, and the third ultrasonic tool holder 113 is used to process the inner diameter of the workpiece. The tool heads 30 of the first ultrasonic tool holder 111 and the second ultrasonic tool holder 112 are arranged in a direction away from the axis of the tool holder body 1, and the tool head 30 of the third ultrasonic tool holder 113 is arranged in a direction away from the tool turret 2, thereby meeting different processing requirements.

[0059] Understandably, the first ultrasonic tool holder 111, the second ultrasonic tool holder 112, and the third ultrasonic tool holder 113 can be arranged side by side along the circumference of the tool holder body 1; or, depending on the installation space, the first ultrasonic tool holder 111, the second ultrasonic tool holder 112, and the third ultrasonic tool holder 113 can be arranged with the ordinary tool holder 12 in a cross-alternating manner, both of which can ensure the overall reliability of the turning device. The mounting protrusions (331, 332, 333) of the tool head 30 of the first ultrasonic tool holder 111, the second ultrasonic tool holder 112, and the third ultrasonic tool holder 113 can adopt a conventional structure. In this case, the tool head 30 only needs to be provided with a comb structure on the end face of the base 32 to achieve reliable installation of the tool head 30 and the amplitude transformer 20. The mounting protrusions (331, 332, 333) adopt a conventional structure, which has good structural stability and high rigidity. The use of a conventional structure does not change the operator's usage habits, thereby ensuring the working efficiency of the device.

[0060] In practical applications, the ultrasonic CNC turning device 100 of this utility model is installed in conjunction with the lathe housing 200. It can be equipped with a conventional XYZ motion platform to drive the ultrasonic CNC turning device 100 to perform translational motion. The ultrasonic tool holder 11 or the ordinary tool holder 12 are positioned corresponding to the machine tool spindle 300. The external control system controls the tool holder body 1 to rotate, that is, drives the ultrasonic tool holder 11 or the ordinary tool holder 12 to rotate. Different tool holders are selected according to different processing requirements and contact the workpiece on the machine tool spindle 300 to achieve processing.

[0061] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
