For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0025] In one embodiment of the present application, as Figures 1-2As shown, a small metal processing engraving drill tool is provided, which comprises a handle 10, a tool body 20 and a tool sleeve 30. The tool sleeve 30 is provided with a mounting cavity 31, and the handle 10 is fixed in the mounting cavity 31. The handle 10 is provided with a damping cavity 11, which is filled with damping particles 12 and used to absorb the vibration energy generated during cutting. One end of the tool body 20 is inserted into the damping cavity 11, and the other end extends out of the handle 10 and is provided with a spiral chip flute 21, which is spirally arranged along the axial direction of the tool body 20.

[0026] Specifically, the handle 10 is fixed in the mounting cavity 31 on the tool sleeve 30, ensuring the close combination of the tool and the tool sleeve 30, and providing stable support for the tool. The handle 10 is provided with a damping cavity 11, which is filled with damping particles 12. These particles can absorb and reduce vibration during cutting, improving the stability and precision of cutting. Reducing vibration can reduce tool wear and prolong tool life. The spiral chip flute 21 is spirally arranged along the axial direction of the tool body 20, which helps to effectively remove chips during cutting, keeps the cutting area clean, and improves cutting efficiency.

[0027] The handle 10 and the tool body 20 are included. The handle 10 is made of high-strength aluminum alloy material and is internally designed with a damping cavity 11. The damping cavity 11 is filled with damping particles 12 made of damping material, which can effectively absorb the vibration energy generated during cutting, reduce tool vibration and improve machining precision. The tool body 20 is made of hard alloy material and is designed with a spiral chip flute 21 at the front end, which can efficiently discharge chips and avoid chip blockage, prolonging the service life of the tool. The design of the drill tool fully considers the characteristics of small metal processing, improves the efficiency and quality of drilling through the innovative application of damping and chip removal technology, prolongs the service life of the tool, and has broad application prospects. Further, appropriate types of cutting fluid such as emulsion or extreme pressure cutting oil can be used to improve chip removal performance.

[0028] In this example, the damping particles 12 are made of damping material. Specifically, the damping cavity 11 in the handle 10 is filled with damping particles 12 made of damping material. When these particles are subjected to vibration energy generated during cutting, they will convert the vibration energy into heat energy through particle collision and friction, thereby reducing tool vibration.

[0029] In this example, manganese copper alloy sheets are attached to the upper and lower surfaces of the handle 10. Specifically, manganese copper alloy sheets are attached to the upper and lower surfaces of the handle as damping materials. This structure can effectively reduce cutting vibration, improve workpiece surface quality, and reduce tool wear.

[0030] In this example, the shank 10 is provided with a circular cavity 13 at one end of the sleeve 30, and the cavity 13 is filled with a damping module 14 for absorbing vibration. Specifically, the cavity 13 is formed by removing part of the material at the front end of the shank 10, and the elastic body and mass block (damping module 14) are added to it, which is used to absorb impact and reduce vibration. Particulate matter is added inside the shank 10, which consumes vibration energy through particle collisions.

[0031] In this example, the shank 10 is provided with a horn-shaped assembly slope 15, and the inside of the sleeve 30 is provided with a guide slope 32 that matches the assembly slope 15. Specifically, the horn-shaped assembly slope 15 on the shank 10 matches the guide slope 32 on the inside of the sleeve 30. This design allows the shank 10 to be aligned and guided into the sleeve 30 during installation, ensuring accurate docking of the shank 10 and the sleeve 30.

[0032] In this example, a mounting seat 40 and a bearing 50 are also included, the bearing 50 is mounted in the mounting seat 40, and the inner ring of the bearing 50 is sleeved outside the sleeve 30, and the outer ring is fixed inside the mounting seat 40. Specifically, this design allows the bearing 50 to support the sleeve 30 while allowing the sleeve 30 to rotate relative to the outer ring of the bearing 50.

[0033] In this example, the mounting seat 40 is provided with a long strip-shaped sliding hole 41, which is used to fix the mounting seat 40. Specifically, the sliding hole 41 can adjust the installation position of the mounting seat 40, and can adjust the position of the tool.

[0034] In this example, the end of the sleeve 30 away from the tool body 20 is provided with a connecting part 33 for connecting with the driving part. Specifically, the end of the sleeve 30 away from the tool body 20 is provided with a connecting part 33, which is used to connect with the driving part (such as a motor, a hydraulic cylinder or other mechanical devices). When the driving part works, it will apply force or torque to the sleeve 30 through the connecting part 33, thereby driving the blade to cut or process.

[0035] In this example, the sleeve 30 is provided with a connecting piece 60, one end of which is clamped with the shank 10. Specifically, the sleeve 30 is designed to fix the shank 10 and the tool body 20, ensuring the stability and safety during tooling or processing. The sleeve 30 is provided with a connecting piece 60, which is usually a part that can be clamped or fixed on the shank 10. One end of the connecting piece 60 is clamped with the shank 10, which means that there is a special groove or interface on the shank 10 that matches the connecting piece 60 and can be firmly fixed in place. When the connecting piece 60 is clamped with the shank 10, the sleeve 30 can be stably fixed on the shank 10, thereby ensuring the stability and accuracy of the tool body 20 during operation.

[0036] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
