[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1-3 The present invention provides an embodiment of a high-precision CNC tool assembly suitable for micromachining, comprising a machining table 1, a support frame 2 fixedly connected to the upper surface of the machining table 1, a controller 3 provided on the outer wall of the support frame 2, a fixing post 4 provided on the lower surface of the controller 3, a tool body 5 slidably connected inside the fixing post 4, a fixing post 6 fixedly connected inside the tool body 5, and a limiting component provided on the outer wall of the fixing post 6, the outer wall of the limiting component slidably connected inside the fixing post 4 and the tool body 5; Specifically, the controller 3 is used to control the operation of the tool body 5. When the controller 3 slides on the outer wall of the support frame 2, it is used to adjust the position of the tool body 5. When the tool body 5 needs to be replaced, first press the limiting component in the center so that it slides inside the fixed post 4 and the tool body 5. After the limiting component slides to the appropriate position, hold and pull the tool body 5 down so that it slides inside the fixed post 4, thereby realizing the quick disassembly of the tool body 5. This makes it convenient for operators to quickly replace the appropriate machining tool according to different operation requirements.

[0022] Reference Figures 1-3The limiting component includes a spring piece 7, the outer wall of which is fixedly connected to the outer wall of the second fixed post 6, and a sliding post 8 is fixedly connected to the outer wall of the spring piece 7. The outer wall of the sliding post 8 is slidably connected to the interior of the first fixed post 4 and the tool body 5; a storage box 9 is fixedly connected to the outer wall of the support frame 2. Specifically, when the sliding column 8 slides inside the fixed column 4 and the tool body 5, it is used to limit or cancel the limit on the fixed column 4 and the tool body 5. The storage box 9 is used to store the working tools for easy access by the operator.

[0023] Reference Figure 1 and Figure 4 A motor 10 is provided on the upper surface of the processing table 1. A transmission assembly is provided at the output end of the motor 10. A piston rod 13 is fixedly connected to the outer wall of the transmission assembly. A sliding block 14 is fixedly connected to one end of the piston rod 13. An air chamber 15 is slidably connected to the outer wall of the sliding block 14. A support block 16 is fixedly connected to the outer wall of the air chamber 15. An air outlet assembly is provided inside the air chamber 15. Specifically, firstly, the motor 10 is turned on. When the motor 10 is working, the output end of the motor 10 and the fixed action of the transmission component will drive the transmission component to rotate, which will further drive the piston rod 13 to move inside the air chamber 15. When the piston rod 13 moves, the fixed action of the piston rod 13 and the sliding block 14 will drive the sliding block 14 to move inside the air chamber 15, further compressing the air inside the air chamber 15 and blowing it out through the air outlet component. This achieves the effect of blowing air onto the machining table 1 during tool processing, avoiding the accumulation of debris, which would affect the machining accuracy.

[0024] Reference Figure 1 and Figure 4 The transmission assembly includes a bidirectional lead screw 11, one end of which is fixedly connected to the output end of the motor 10. A threaded block 12 is threadedly connected to the outer wall of the bidirectional lead screw 11. The outer wall of the threaded block 12 is slidably connected to the inside of the processing table 1. The outer wall of the threaded block 12 is fixedly connected to the outer wall of the piston rod 13. The air outlet assembly includes a vent pipe 17, the outer wall of which is fixedly connected to the inside of the air chamber 15. An air blowing plate 18 is provided on the outer wall of the vent pipe 17. The lower surface of the air blowing plate 18 is fixedly connected to the upper surface of the processing table 1. A sliding groove 19 is provided inside the processing table 1. The threaded block 12 is slidably connected to the inside of the processing table 1 through the sliding groove 19. The outer wall of the transmission assembly is slidably connected to the inside of the processing table 1. The lower surface of the support block 16 is fixedly connected to the upper surface of the processing table 1. The lower surface of the air outlet assembly is fixedly connected to the upper surface of the processing table 1. Specifically, when the motor 10 is running, the output end of the motor 10 and the fixed action of the bidirectional lead screw 11 will drive the bidirectional lead screw 11 to rotate, which will further drive the threaded block 12 to move. When the threaded block 12 moves, it will drive the piston rod 13 to move, which will further drive the sliding block 14 to slide inside the air chamber 15, thereby compressing the air inside the air chamber 15 and blowing the compressed air onto the processing table 1 through the air pipe 17 and the air blowing plate 18. The slide groove 19 is used to limit the movement trajectory of the threaded block 12, thereby improving the stability of the threaded block 12 when it moves.

[0025] Working principle: When it is necessary to replace the tool body 5, by pressing the spring piece 7, the sliding column 8 is driven to slide inside the fixed column 4 and the tool body 5, further releasing the limit. Then, the tool body 5 is pulled down to disengage it from the fixed column 4. During installation, the tool body 5 is first inserted into the fixed column 4. Then, the spring piece 7 releases its elasticity to make the sliding column 8 lock into the fixed column 4. The sliding of the sliding column 8 enables quick disassembly and assembly of the tool, which is convenient for operators to replace different tools according to actual processing needs and ensures the stability of the tool during processing. First, the motor 10 is started to drive the bidirectional lead screw 11 to rotate, which in turn drives the threaded block 12 to move along the slide groove 19 inside the machining table 1. This, in turn, pushes the piston rod 13 and the sliding block 14 to slide inside the air chamber 15, further compressing the air in the air chamber 15 and spraying it out from the air blowing plate 18 through the air pipe 17. Through the combined action of the bidirectional lead screw 11, the threaded block 12, the piston rod 13, the sliding block 14, the air chamber 15, the air pipe 17, and the air blowing plate 18, the debris on the machining table 1 is blown away during the machining process, thus preventing the accumulation of debris from affecting the machining accuracy of the tool.
