[0020] Reference Figures 1-4 A three-dimensional composite machining tool includes a tool holder 1, a tool shank 2 on the tool holder 1, multiple planes 13 on the surface of the tool shank 2, two mounting slots 4 at the bottom of the tool holder 1, and two detachable cutting blades 5 fixedly installed in the two mounting slots 4 respectively. The cutting blades 5 are installed in the mounting slots 4, and a coarse cutting head 7 is provided at one end of the cutting blade 5. A connecting slot 6 is provided on one side of the coarse cutting head 7, and a detachable fine cutting head 8 is fixedly installed in the connecting slot 6.

[0021] The blade holder 1 has multiple mounting holes 10 on both sides that communicate with the mounting groove 4. A first bolt is installed in the mounting hole 10. The blade 5 is fixedly installed in the mounting groove 4 by the first bolt. The installation of the blade 5 in the mounting groove 4 is achieved by multiple first bolts. At the same time, the structure of the first bolt thread installation also facilitates later maintenance, disassembly and replacement.

[0022] A connecting hole 12 is provided on one side of the fine cutter head 8. A second bolt is installed in the connecting hole 12. The thread of the second bolt passes through the fine cutter head 8 and is inserted into the inner wall of the connecting groove 6. The coarse cutter head 7 can perform rough machining on the parts. The fine cutter head 8, which can perform fine machining, is directly installed on one side of the coarse cutter head 7. By combining the coarse cutter head 7 and the fine cutter head 8, rough machining and fine machining can be seamlessly connected. At the same time, the fine cutter head 8 can be detachably installed on one side of the coarse cutter head 7 by the second bolt. The detachable structure facilitates later maintenance.

[0023] The connection between the tool holder 1 and the tool shank 2 is provided with a connecting part 11 with a diameter larger than that of the tool shank 2. The connecting part 11 is provided between the tool holder 1 and the tool shank 2, so that a gap is formed between the tool holder 1 and the tool shank 2, which facilitates the operation.

[0024] The end of the shank 2 away from the tool holder 1 is provided with a shank head 3. The shank head 3 is made of corrosion-resistant rubber. When installing this tool, the shank head 3 is provided at the end for buffering and shock absorption. It has a certain degree of elasticity and has a certain shock absorption effect.

[0025] The coarse cutter head 7 and the fine cutter head 8 form an angle between their ends, which is less than 180 degrees. The two fine cutter heads 8 are located on the same side of the coarse cutter head 7. The side of the tool holder 1 where the two blades 5 are mounted is an arc-shaped surface. The blades 5 are provided with protrusions 9, which are engaged with the edge of the mounting groove 4. The coarse cutter head 7 and the fine cutter head 8 form an angle to facilitate the machining of parts. The protrusions 9 are used to limit the installation and fixation of the blades 5.

[0026] The drive end of the drive motor for driving the cutting tool in the lathe is fixedly connected to the tool holder 2. Multiple planes 13 are provided on the surface of the tool holder 2. The drive end can be fixedly engaged with the tool holder 2 through the planes 13. At the same time, the drive end can change the orientation angle of the cutting tool 5 by rotating within the range of the planes 13, thus changing the cutting head. During machining, the position of one cutting tool 5 can be changed to another cutting tool 5, or the position of the coarse cutting head 7 can be changed to the fine cutting head 8. When turning parts, the coarse cutting head 7 is used for rough machining, and the fine cutting head 8 is used for fine machining. The first bolt can be used to remove or install the cutting tool 5 in the mounting slot 4, which is convenient for maintenance and enables quick replacement. After replacement, there is no need to remeasure the tool length, which effectively improves the overall production time.

[0027] This device adopts a dual-head design, achieving high integration through a composite design, making installation more convenient. The dual-head dual-track design, through overlapping roughing and finishing trajectories, can improve the processing efficiency of relevant parts by 50%, maintain a constant finishing allowance, and ensure stable appearance quality after machining. It also saves test run time; the time previously spent testing two tools separately can now be reduced to testing one tool, improving changeover and abnormal tool change efficiency. With roughing and finishing combined, the tool only performs one machining operation. For each workpiece processed, the turret travel trajectory is reduced by one, which can reduce wear on the turret, leadscrew, and guide rail. The constant roughing and finishing allowances of the dual-head design result in more stable workpiece dimensions, more stable workpiece surface quality and roughness, and more stable product runout and dynamic balance quality.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
