[0002] In the field of machining, especially during the drilling and tapping of soft metals such as aluminum alloys, aluminum chips easily adhere to the shank and clamping parts of the drill bit. If these chips enter the rotating clamping head, they can not only reduce clamping accuracy but also cause equipment wear or even malfunction.

[0003] Traditional solutions often rely on regular manual cleaning or simple protective covers, but these are inefficient and fail to completely prevent debris intrusion. Furthermore, aluminum shavings generated during machining can adhere to the tool holder surface, potentially affecting tool cooling and machining stability, thereby reducing workpiece quality.

[0004] To address the aforementioned issues, an improved tool holder treatment mechanism to prevent aluminum shavings from adhering is now designed. Utility Model Content

[0027] Working principle of the tool holder treatment mechanism that prevents aluminum shavings from adhering:

[0028] Select a suitable sealing rubber ring 15 according to the size of the drill bit 3 and snap it into the inside of the frame 6. During installation, pass the mounting head of the drill bit 3 through the sealing rubber ring 15 and fix it inside the rotating clamping head 2. The sealing rubber ring 15 seals the lower end of the rotating clamping head 2, preventing aluminum chips from entering the inside of the rotating clamping head 2, so that the rotating clamping head 2 can accurately clamp the drill bit 3.

[0029] When in use, the motor 18 is started, and the output end of the motor 18 drives the reciprocating lead screw 20 to rotate. The reciprocating lead screw 20 drives the moving block 19 to move back and forth along the inner wall of the fixed frame 14. The moving block 19 drives the slider 13 to move. The slider 13 drives the second connecting rod 11 to move. The second connecting rod 11 drives the first connecting rod 10 to move. The first connecting rod 10 drives the fixed ring 9 to move. As the drill bit 3 rotates, the fixed ring 9 drives the cleaning brush 16 to brush the side wall of the drill bit 3. The fixed ring 9 drives the annular tube 7 and the nozzle 17 to move, so that the nozzle 17 washes the side wall of the drill bit 3.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
