[0029] Reference Figure 1-4A composite boring bar with adjustable blade position includes a boring bar body 1. Two slots 3 are formed on the outer periphery of the boring bar body 1. Multiple mounting areas 6 are provided on the outer wall of each mounting area 6. A fine-tuning tool holder 7 is provided on the outer wall of each mounting area 6. A sliding groove 10 is formed inside the fine-tuning tool holder 7. A tool shank 17 is rotatably mounted inside the fine-tuning tool holder 7. A gear 16 is fixedly connected to the outer side of the tool shank 17. A machining blade 11 is slidably connected inside the sliding groove 10. A rack 12 is fixedly connected to the side of the machining blade 11 closest to the gear 16, and the rack 12 meshes with the gear 16. A locking bolt a is threadedly connected to the outer side of the fine-tuning tool holder 7. 20. The machining insert 11 is locked inside the sliding groove 10 by the locking bolt a20. When the boring bar body 1 is used to process the workpiece, the rotation of the indexing plate 15 can drive the tool holder 17 to rotate, and at the same time drive the gear 16 to rotate. This allows the machining insert 11 to move linearly under the action of the limiting component, thereby achieving the purpose of fine adjustment of the machining insert 11. By using the locking bolt a20, the fine adjustment tool holder 7 after the position is adjusted can be locked, so that the corresponding position of the machining insert 11 can be adjusted according to different processing requirements, thereby improving the applicability of the boring bar body 1.

[0030] Specifically, the top of the tool holder 17 is equipped with a scale assembly, which includes a rotary dial 15 fixedly connected to the top of the tool holder 17. When the operator needs to adjust the machining position of the cutting tool 11, a hex screwdriver can be inserted into the hexagonal screw groove 14 and rotated. The rotation of the tool holder 17 also drives the scale dial 18 to rotate. At this time, the operator can read the travel distance of the cutting tool 11 according to the scale dial 18 and the indicator head 21, thereby improving the machining accuracy of the workpiece. The top of the tool holder 17 extends to the outside of the fine-tuning tool holder 7. The top of the rotary dial 15 is fixedly connected to the scale dial 18. The top of the tool holder 17 has a hexagonal screw groove 14, and the top of the fine-tuning tool holder 7... A marking head 21 is fixedly connected to one side of the dial 18. A limiting component is provided on the outer side of the machining blade 11. The limiting component includes a limiting groove 19 opened inside the fine-tuning tool holder 7 and located on both sides of the sliding groove 10. The limiting groove 19 is slidably connected to a limiting element 13. Through the cooperation of the limiting element 13 and the limiting groove 19, the extension range of the machining blade 11 can be limited, and the stability of the machining blade 11 during the adjustment process can be ensured. The two limiting elements 13 are fixedly connected to both sides of the machining blade 11 respectively. A knob key 9 is provided at one end of the boring tool body 1. A tool holder 2 is provided on the side of the knob key 9 away from the boring tool body 1, which facilitates docking with external equipment.

[0031] Specifically, the knob 9, the tool holder 2, and the boring bar body 1 are integrally formed. The fine-tuning tool holder 7 has an assembly groove 8 inside, and a locking bolt b is provided inside the assembly groove 8 so as to achieve the overall assembly purpose of the fine-tuning tool holder 7 by locking the bolt b, thereby improving the ease of disassembly and assembly. The fine-tuning tool holder 7 is connected to the mounting area 6 by the locking bolt b. A circular groove 4 is provided on the side of the boring bar body 1 away from the knob 9. Several water outlet holes 5 are provided inside the boring bar body 1 and on the outer periphery of the circular groove 4 so as to allow cooling water to flow out and reduce the cutting temperature.

[0032] Working principle: First, the operator can use the locking bolt b to assemble the fine-tuning tool holder 7 into the installation area 6. When the operator needs to adjust the processing position of the processing blade 11, a hex screwdriver can be inserted into the hex screw groove 14 and rotated. The rotation of the tool holder 17 will drive the scale 18 and gear 16 to rotate simultaneously. The rotation of gear 16 enables the processing blade 11 to move linearly under the action of the limiting component, thereby achieving the purpose of fine-tuning the processing blade 11. By using the locking bolt a20, the fine-tuning tool holder 7 can be locked after the position is adjusted, so that the corresponding position of the processing blade 11 can be adjusted according to different processing requirements. At this time, the operator can read the travel distance of the processing blade 11 according to the scale 18 and the marking head 21, thereby improving the processing accuracy of the workpiece.
