[0031] See also Figures 1 to 3 As shown, the utility model provides an ultrasonic tool handle, comprising:

[0032] The tool handle body 10 includes a main body 11 and a mounting portion 12. The mounting portion 12 is provided at one end of the main body 11, and the mounting portion 12 is used to be inserted into an external machine tool spindle; the other end of the main body 11 has a receiving cavity 101;

[0033] The energy transmission component 20 is disposed on the outer periphery of the main body 11 and cooperates with the external energy emission component to realize energy transmission;

[0034] The horn 30 is partially disposed in the accommodating cavity 101 of the main body 11, and a groove 31 is disposed on the outer periphery of the horn 30;

[0035] The effective installation length of the installation portion 12 is L1, and the axial length between the end of the main body 11 close to the installation portion 12 and the energy transmission component 20 is L2, satisfying L2=n1×L1, 0<n1≤5.

[0036] Specifically, the vibration mode of the ultrasonic shank can be adjusted by providing a groove 131 on the horn 30. Among the currently commonly used ultrasonic shanks, for a specific type of shank, the effective installation length L1 of the mounting portion 12 is a certain value, the axial length L2 is the distance between the energy transmission component 20 and the end of the main body 11 close to the mounting portion 12, and n1 can be 0.5, 1, 2, 2.5, 3, 4, 5 or any value in the range, that is, according to the effective installation length of the mounting portion 13, the axial length of the main body 11 can be adaptively increased to avoid interference with the machine tool, improve its scope of application, and ensure processing efficiency.

[0037] Furthermore, the axial length L2≥10 mm. When the relationship L2=n1×L1 is satisfied, the specific value of L2 can be 10 mm, 20 mm, 30 mm, 40 mm, 50 mm or any value within the range, which can meet the needs of actual machine tool installation.

[0038] Furthermore, a tool clamping groove 111 and a positioning groove 112 connected to the tool clamping groove 111 are provided on the outer periphery of the end of the main body 11 close to the mounting portion 12, so as to facilitate circumferential positioning with the tool changing fixture and ensure the reliability of the overall installation of the ultrasonic tool handle.

[0039] Furthermore, the energy transmission component 20 includes a transmission shell 21 and a transmission module 22 arranged in the transmission shell 21. The outer peripheral surface of the main body 11 extends axially and radially to form the transmission shell 21. An installation cavity is formed between the inner wall of the transmission shell 21 and the outer wall of the main body 11; the opening of the installation cavity is set toward or away from the installation portion 12, and the transmission module 22 is arranged in the installation cavity.

[0040] Specifically, the transmission shell 21 and the main body 11 are integrally formed, which can simplify the assembly process of the energy transmission component 20, reduce assembly errors, and overcome the problem of the dynamic balance of the ultrasonic tool holder caused by assembly errors; on the other hand, it can ensure the installation stability of the energy transmission component 20, ensure the installation coaxiality of the transmission shell 21 and the main body 11, and ensure the processing efficiency; in addition, under high rotation speed, the transmission shell 21 and the main body 11 adopt an integrated structure, which also reduces the risk of loose connection and falling off in the split structure.

[0041] Furthermore, the axial length of the energy transmission component 20 is L3, satisfying L3=n2×L1, 0<n2<1, and n2 can specifically be 0.2, 0.4, 0.6, 0.8 or any value within the range, which facilitates the reliable installation of the transmission module 22 in the transmission shell 21, ensures the installation quality of both, and enables the energy transmission component 20 to stably transmit electrical energy with the external energy emitting component, which can meet actual processing requirements.

[0042] Furthermore, the overall axial length of the main body 11 is L4, satisfying L4=n3×L1, 1≤n3<5, and n3 can specifically be 1, 2, 3, 4, 4.5 or any value within the range. According to the effective installation length of the mounting portion 13, the overall axial length of the main body 11 can be adaptively increased to avoid interference with the external machine tool spindle, and to provide sufficient installation space for the amplitude transformer 30 to ensure that the amplitude transformer 30 stably generates ultrasonic amplitude to meet actual needs.

[0043] Furthermore, the maximum outer diameter of the main body 11 close to the mounting portion 12 is D1, and the outer diameter of the energy transmission component 20 is D2, satisfying D2=n4×D1, 0<n4≤3, and n4 can specifically take values ​​of 0.5, 1, 1.5, 2, 2.5, 3 or any value within the range, so as to facilitate the installation and matching of the energy transmission component 20 and ensure transmission efficiency and processing efficiency.

[0044] Furthermore, the outer circumference of the horn 30 is provided with a plurality of spiral grooves 31 along the circumferential direction, and the spiral grooves 31 are arranged in a clockwise or counterclockwise spiral, that is, in a forward or reverse spiral ( Figure 4 ).

[0045] It is understandable that the groove 131 can also adopt an inclined groove or a groove structure of other shapes. The transducer assembly 32 on the amplitude transformer 30 is connected to the transmission module 22 of the energy transmission assembly 20. The longitudinal vibration generated by the transducer assembly 32 can generate a longitudinal-torsional composite vibration at the end of the amplitude transformer 30 after the amplitude transformer 30 with the groove is variable. This can improve the processing accuracy and efficiency.

[0046] Furthermore, the end of the amplitude changing rod 30 protruding from the shank body 10 is a tool connecting part 33, and the outer diameter of the tool connecting part 33 is D3; the axial length between the end of the spiral groove 31 close to the tool connecting part 33 and the end of the tool connecting part 33 is L5, satisfying L5=n5×D3, 0<n5≤5, and n4 can specifically take values ​​of 1, 1.5, 2, 2.5, 3, 4, 5 or any value within the range, which can ensure the stability of the connection between the tool connecting part 33 and the tool and ensure the actual processing efficiency.

[0047] It is understandable that the tool connecting portion 33 can be matched with clamping parts such as collets of different models (not shown in the figure) to install tools of different sizes, meet the processing requirements of different materials, and improve the processing application range of the tool handle.

[0048] Furthermore, the axial length of the amplitude transformer 30 protruding from the shank body 10 is L6, and the pitch P of the spiral groove 31 satisfies P=n6×π×L6, 0<n6≤1, and n6 can specifically be 0.2, 0.4, 0.6, 0.8 or any value within the range. While ensuring the structural strength of the amplitude transformer 30, the ultrasonic vibration can generate stable longitudinal-torsional composite vibration when passing through the spiral groove 31, thereby improving the processing efficiency.

[0049] The ultrasonic tool holder provided by the utility model can avoid interference with the main shaft of the machine tool. The tool holder has high structural rigidity and stability, can output stably and generate a larger amplitude, thereby improving processing efficiency and being applicable to processing of more types of products.

[0050] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
