Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 , the utility model provides a technical solution:

[0021] A tool handle conversion clamping device for a tool presetter comprises a connecting portion 1, a positioning portion 2 and a locking portion 3, wherein the connecting portion 1 comprises a first tool handle connecting piece 101, the locking portion 3 is arranged on the outer wall of the first tool handle connecting piece 101, and the locking portion 3 is not less than two groups, the positioning portion 2 is fixedly connected to the bottom of the first tool handle connecting piece 101, the bottom of the positioning portion 2 is fixedly connected to an intermediate conversion portion 4, the connecting portion 1 further comprises a second tool handle connecting piece 102, the second tool handle connecting piece 102 is fixedly connected to the bottom of the intermediate conversion portion 4, and the utility model is provided with a connecting portion The connection part 1, the positioning part 2 and the locking part 3 are used in coordination. The connection part 1 is responsible for connecting with the tool handle, which can ensure precise coordination with the tool handle, and the locking part 3 is used to strengthen the positioning to prevent the tool handle from falling off during the processing. The intermediate conversion part 4 is provided as a key part connecting the first tool handle connecting part 101 and the second tool handle connecting part 102, which has extremely high strength and rigidity to withstand the cutting force during the processing. In addition, it can ensure that the axes of the two sets of tool handles are accurately aligned, reduce the radial runout error during the processing of the tool head, and thus improve the processing accuracy;

[0022] The locking part 3 includes a threaded column 301, which is arranged on the outer wall of the first handle connecting piece 101, one end of which is fixedly connected to a knob 302, and a threaded through hole 5 matching the threaded column 301 is provided on the outer wall of the first handle connecting piece 101, and the threaded column 301 is threadedly connected to the inside of the threaded through hole 5;

[0023] Specifically, by setting the threaded column 301, the knob 302 and the threaded through hole 5 for coordinated use, the threaded column 301 can be driven to rotate by rotating the knob 302, thereby enhancing the positioning of the tool handle, preventing the tool handle from falling off during the processing, and facilitating the processing stability.

[0024] The first tool handle connecting piece 101 is made of high-strength alloy, and two groups of first positioning grooves 6 are arranged on the inner wall of the first tool handle connecting piece 101. The use of high-strength alloy makes the first tool handle connecting piece 101 have higher strength and stability. During the use of the tool presetter, such high strength and stability can ensure that the tool handle is not easily deformed or damaged during the clamping and conversion process, thereby ensuring the accuracy and reliability of the tool presetter. The first positioning groove 6 is arranged on the inner wall of the first tool handle connecting piece 101 to ensure the accurate positioning of the tool handle during the clamping process. This positioning method reduces the error of human operation and improves the calibration accuracy of the tool presetter. At the same time, the design of the first positioning groove 6 also makes the clamping of the tool handle more stable, avoiding the loosening or falling off of the tool handle due to vibration or impact during the cutting process;

[0025] The intermediate conversion part 4 is arranged in a truncated cone, and the material of the intermediate conversion part 4 is arranged to be made of high-strength alloy steel. The high-strength alloy steel has high tensile strength, compressive strength and bending strength, which can ensure that the tool handle is not easily deformed or damaged when it is frequently used or subjected to large forces. The material also has good wear resistance, and can maintain a low wear rate during long-term use, thereby extending the service life of the device. The design of the truncated cone shape enables the intermediate conversion part to better withstand the pressure and torque from the tool, thereby improving the stability of the device. The design of the intermediate conversion part 4 in the shape of a truncated cone can adapt to tool handles of different specifications and models, thereby improving the versatility and compatibility of the device.

[0026] It also includes a second positioning groove 7, which is opened on the outer wall of the intermediate conversion part 4, and the number of the second positioning grooves 7 is not less than two groups. The design of the second positioning groove 7 can provide a more accurate positioning reference, ensuring that the position of the tool handle in the conversion clamping device is stable and accurate. By cooperating with the positioning mechanism inside the tool presetter, the positioning error can be further reduced and the accuracy of tool adjustment can be improved. When the tool is cutting at high speed or subjected to a large cutting force, this stability can ensure that the tool will not be displaced due to vibration or impact, thereby ensuring the stability and safety of the processing process;

[0027] An elastic member 8 is provided on the inner wall of the second tool handle connecting member 102, and the material of the elastic member 8 is set to be a rubber pad. By providing the elastic member 8, such as a spring or a rubber pad, the small gap between the tool handle and the second tool handle connecting member 102 can be filled, thereby ensuring that the tool handle is stably clamped in the connecting member. This stable clamping helps to reduce tool displacement caused by vibration or impact during processing, thereby ensuring processing accuracy.
