However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments. Embodiment 1

[0027] Referring to Figures 1 to 3 , this is the first embodiment of the present invention. This embodiment provides an ultrasonic turning tool, which includes a support mechanism 1, a tool mechanism 2, and a transducer mechanism 3. The tool mechanism 2 is arranged on the support mechanism 1, and the ultrasonic frequency electrical oscillation is converted into ultrasonic mechanical vibration through the transducer mechanism 3, so as to perform ultrasonic vibration on the tool mechanism 2 and thus process the workpiece.

[0028] Specifically, it includes a support mechanism 1, a tool mechanism 2, and a transducer mechanism 3; the tool mechanism 2 is connected to the support mechanism 1, and the support mechanism 1 can support the tool mechanism 2; the transducer mechanism 3 can convert ultrasonic frequency electrical oscillation into ultrasonic mechanical vibration and can drive the tool mechanism 2.

[0029] In one embodiment, the support mechanism 1 can provide multi-point support for the tool mechanism 2.

[0030] In summary, the power frequency alternating current energy is converted into ultrasonic frequency electrical oscillation with a certain power output by an ultrasonic power supply, and the transducer mechanism 3 converts the ultrasonic frequency electrical oscillation into ultrasonic mechanical vibration to drive the tool mechanism 2 to generate ultrasonic vibration, which acts on the workpiece processing surface to form the workpiece. Embodiment 2

[0031] Refer to Figures 1 to 5 , which is the second embodiment of the present invention. In the previous embodiment, the ultrasonic turning tool includes a support mechanism 1, a tool mechanism 2, and a transducer mechanism 3. The tool mechanism 2 is arranged on the support mechanism 1, and the ultrasonic frequency electrical oscillation is converted into ultrasonic mechanical vibration by the transducer mechanism 3, so as to perform ultrasonic vibration on the tool mechanism 2, thereby machining the workpiece.

[0032] Specifically, it includes a support mechanism 1, a tool mechanism 2, and a transducer mechanism 3; the tool mechanism 2 is connected to the support mechanism 1, and the support mechanism 1 can support the tool mechanism 2; the transducer mechanism 3 can convert ultrasonic frequency electrical oscillation into ultrasonic mechanical vibration and can drive the tool mechanism 2.

[0033] In one embodiment, the support mechanism 1 can provide multi-point support for the tool mechanism 2.

[0034] Furthermore, the support mechanism 1 includes a base 11 and a support platform assembly 12; one side of the base 11 is connected to the support platform assembly 12, and the support platform assembly 12 can provide point support for the tool mechanism 2.

[0035] In one embodiment, by arranging the support platform assembly 12 above the base 11, the tool mechanism 2 can be double-supported by the support platform assembly 12. The double support enhances rigidity and enables stable cutting.

[0036] Refer to Figure 4 , Figure 5 , it should be noted that the tool mechanism 2 can be supported laterally by connecting the side surface of the support platform assembly 12 to the tool mechanism 2, and the tool mechanism 2 can be multi-point supported through the inner side of the support platform assembly 12, so as to achieve double support.

[0037] It should be noted that the support platform 121 is supported on the side of the tool bar 21 through the first connecting member 122, and the tool mechanism 2 inside the support platform 121 can be point-supported through the second support member 123, so as to form a double support for the tool mechanism 2.

[0038] Furthermore, the support platform assembly 12 includes a support platform 121, a first connecting member 122, and a second support member 123; the first connecting member 122 is arranged on the side of the support platform 121, and multiple groups of second support members 123 are arranged on the support platform 121. The second support member 123 can point-support the tool mechanism 2 inside the support platform 121, and the tool mechanism 2 is connected to the side of the support platform 121 through the first connecting member 122.

[0039] In one embodiment, the first connecting member 122 can connect the side of the tool bar 21 and the side of the support platform 121 together.

[0040] It should be noted that the tool bar 21 is arranged inside the support platform 121, and there is a certain distance between the tool bar 21 and the inside of the support platform 121. Multiple groups of second support members 123 can perform multi-point support on the surface of the tool bar 21.

[0041] In one embodiment, by setting the second support member 123, point contact with the surface of the tool bar 21 can be achieved.

[0042] It should be noted that if non-node contact is adopted, it will affect the output effect of the ultrasonic vibration mode, while the present device adopts point contact, which can not only support the tool bar 21, but also enhance the rigidity without affecting the vibration mode.

[0043] Furthermore, the second support member 123 includes a support hole 1231 and a bead extreme screw 1232; multiple groups of support holes 1231 are formed on the support platform 121 and the base 11, and the bead extreme screw 1232 is arranged in the support hole 1231. The bead extreme screw 1232 can support the surface of the tool mechanism 2.

[0044] In one embodiment, point contact with the surface of the tool bar 21 can be achieved through the bead extreme screw 1232 to play a supporting role.

[0045] Furthermore, multiple groups of bead extreme screws 1232 are arranged in a circle and are all in one plane. Multiple groups of bead extreme screws 1232 can point-support the surface of the tool mechanism 2.

[0046] In one embodiment, the bead extreme screws 1232 can be set to four groups, which are arranged in a circle on the surface of the tool bar 21, and the four groups of bead extreme screws 1232 arranged in a circle are in the same plane, avoiding the situation of the tool bar 21 tilting.

[0047] Further, multiple groups of bead polarimeter screws 1232 are arranged circumferentially and / or horizontally. The multiple groups of bead polarimeter screws 1232 can evenly perform point support on the surface of the tool mechanism 2 at multiple points.

[0048] It should be noted that multiple groups of bead polarimeter screws 1232 can be arranged horizontally and circumferentially. The multiple groups of bead polarimeter screws 1232 can be not in the same plane and can be evenly arranged on the surface of the tool bar 21.

[0049] Further, the tool mechanism 2 includes a tool bar 21, and a turning tool 22 is connected to one side of the tool bar 21; different types of turning tools 22 can be connected to the tool bar 21.

[0050] In one embodiment, the tool bar 21 and the turning tool 22 are installed in a quick-detachable manner, and different types of turning tools 22 can be replaced according to the usage scenario.

[0051] Further, the transducer mechanism 3 includes a horn 31. One side of the horn 31 is connected to a screw 36. A piezoelectric ceramic 32 and an electrode plate 33 are also arranged on the side surface of the horn 31. A rear cover plate 34 and a nut 35 are arranged on the screw 36; the piezoelectric ceramics 32 and the electrode plates 33 are alternately stacked.

[0052] Further, the piezoelectric ceramic 32 has positive and negative poles, and the same polarities of multiple groups of piezoelectric ceramics 32 face each other.

[0053] In one embodiment, the piezoelectric ceramics 32 and the electrode plates are alternately stacked. The piezoelectric ceramic 32 has positive and negative poles, and the same polarities of the piezoelectric ceramics 32 face each other. With the input of alternating current energy, the transducer can generate corresponding vibrations.

[0054] In summary, through the support mechanism 1, the present invention can perform multi-point contact support on the tool mechanism 2. Non-node contact will affect the ultrasonic vibration mode and the output effect. Therefore, the bead polarimeter screw can reduce the influence with point contact, enhance the rigidity without affecting the vibration mode. The power frequency alternating current energy is converted into ultrasonic frequency electrical oscillation with a certain power output through the ultrasonic power supply. The transducer mechanism 3 converts the ultrasonic frequency electrical oscillation into ultrasonic mechanical vibration. The tool mechanism 2 fixed at the end of the horn 31 generates ultrasonic vibrations through the horn 31, acts on the workpiece processing surface, and forms the workpiece.
