[0024] Please refer to Figures 1-3 , a combined rough boring tool, including a mounting post 1, a mounting base 2 installed at the upper end of the mounting post 1, and a tool 3 installed inside the base 2. It further includes: a threaded tube, a fine-tuning bolt 4 is arranged at the side end of the base 2, and one end of the fine-tuning bolt 4 penetrates the surface of the base 2 and is connected to a lead screw 5, and the lead screw 5 is installed inside a fixed seat 6. Two limit posts 7 are installed on the surface of the fixed seat 6, and a center block 8 is arranged at the center of the two limit posts 7. The side end of the center block 8 is fixedly connected to one end of the tool 3, and a fixing bolt 9 is fixedly connected to the center of the center block 8. An adjustment assembly is installed inside the base 2 for adjusting the angle of the tool 3. The adjustment assembly includes the fine-tuning bolt 4, the lead screw 5, the fixed seat 6, the limit posts 7, the center block 8 and the fixing bolt 9. These components work together to allow fine adjustment of the angle of the tool 3.

[0025] Furthermore, an installation groove 10 is arranged at the other end of the tool 3, a tool block 11 is installed inside the installation groove 10, a screw is installed at the center of the tool block 11, and a semi-circular groove is arranged at the inner end of the installation groove 10 corresponding to the tool block 11. The semi-circular groove in the installation groove is to allow the tool block to have a certain degree of freedom during adjustment, so as to better adapt to different machining conditions and tool shapes.

[0026] Furthermore, one end of the fixing bolt 9 penetrates the surface of the fixed seat 6 and extends to the outside of the base 2, and the fixing bolt 9 fixes the center block 8 to the fixed seat 6 and the base 2 together.

[0027] Furthermore, an empty groove is arranged inside the fixed seat 6, and the two limit posts 7 are installed inside the empty groove, and the two limit posts 7 move inside the empty groove.

[0028] Furthermore, two through holes are arranged on the surface of the base 2, fixing bolts are installed inside the through holes, and the fixing bolts penetrate the base 2 and the fixed seat 6, and the fixing bolts fix the fixed seat 6 to the base 2 together.

[0029] Furthermore, the inner ends of the two tools 3 are arranged in an arc shape. When the two tools 3 are adjusted in angle, the collision between the two tools is reduced.

[0030] Furthermore, the adjustment assembly includes a fine-tuning bolt 4, a lead screw 5, a fixed seat 6, a limit post 7, a center block 8, and a fixing bolt 9. The fine-tuning bolt 4 is arranged at the side end of the base 2, and one end of the fine-tuning bolt 4 penetrates through the surface of the base 2 and is connected to the lead screw 5. The lead screw 5 is installed inside the fixed seat 6. Two limit posts 7 are installed on the surface of the fixed seat 6. A center block 8 is arranged at the center of the two limit posts 7.

The fine-tuning bolt 4, the lead screw 5, the fixed seat 6, the limit post 7, the center block 8, and the fixing bolt 9 work together to allow fine-tuning of the angle of the tool 3.

[0031] Working principle: The tool 3 is initially fixed on the fixed seat 6 through the cooperation of the center block 8 and the limit post 7. This design ensures the stability and accuracy of the tool during installation. When the angle of the tool needs to be adjusted, the user can rotate the fine-tuning bolt 4 to achieve this. Rotating the fine-tuning bolt will drive the connected lead screw 5 to rotate inside the fixed seat 6. Due to the threaded connection between the lead screw and the fine-tuning bolt, the rotation of the lead screw will be converted into linear motion. This linear motion is transmitted to the tool through the center block 8, thereby changing the angle of the tool. The design of the limit post 7 and the center block 8 limits the offset of the tool during the adjustment process, ensuring the accuracy and stability of the adjustment process. After adjusting the angle of the tool, the user can tighten the fixing bolt 9 to lock the entire structure. The fixing bolt penetrates through the fixed seat 6 and the base 2, firmly connecting them together, thereby ensuring that the tool will not be displaced due to vibration or external force during the machining process. The connection between the base 2 and the mounting post 1 and the fixing bolt connection between the base 2 and the fixed seat 6 together constitute the support system of the entire structure.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
