[0015] To make the above-mentioned objectives, features, and advantages of this utility model more readily understood, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] like Figures 1-3 As shown, this utility model provides an armor grinder with an integrally formed structure of bushing and bearing, the integrally formed structure of bushing and bearing of the armor grinder includes: The machine body 1 contains a motor 2, the top of the motor 2 contains a bearing 3, the bearing 3 contains a bushing 4, and the bearing 3 and the bushing 4 are integrally formed. The bushing 4 contains a rotating shaft 5, and the upper end of the rotating shaft 5 contains a grinding head 6.

[0017] Specifically, the machine body 1 houses a motor 2, with an eccentric shaft at its top connected to a bearing 3. The bearing 3 has a motor groove 32 at its bottom, which perfectly accommodates the eccentric shaft, preventing it from detaching and allowing only rotation without vertical movement. The upper part of the bearing 3 has a bearing groove 31 to fully or partially accommodate a bushing 4, ensuring it cannot detach under any circumstances. The bearing 3 and bushing 4 are integrally formed, with the metal bearing and plastic bushing significantly improving concentricity and optimizing the component. The upper end of the bushing 4 has a bushing groove 41, which is hexagonal in shape, to fully or partially accommodate a rotating shaft 5. The rotating shaft 5 is designed as a hexagonal prism, ensuring it fits perfectly into the bushing groove 41, preventing detachment and movement. The upper end of the rotating shaft 5 has a grinding head 6, with a limiting post 61 at its lower end. The upper end of the rotating shaft 5 has a limiting groove 51, with the limiting post 61 partially or fully embedded within it, allowing only rotation and preventing detachment. This structure significantly improves concentricity while possessing the characteristics of both metal and plastic. It optimizes components, simplifies assembly, ensures long-term high-speed stability, and reduces noise.

[0018] In some embodiments, the bearing 3 is provided with a bearing groove 31 and a motor groove 32. The bearing groove 31 is used to accommodate the bushing 4, and the motor groove 32 is connected to the motor 2.

[0019] Specifically, the motor 2 has an eccentric shaft at its top, and the motor slot 32 can accommodate the eccentric shaft in whole or in part. The eccentric shaft cannot be disengaged and can only rotate inside the motor slot. The bearing slot 31 can accommodate the bushing 4 in whole or in part and cannot be disengaged. The bearing and bushing are integrally formed, which significantly improves concentricity. Furthermore, due to the metal material of the bearing and the plastic material of the bushing, the optimized components share the characteristics of both metal and plastic.

[0020] In some embodiments, the upper end of the bushing 4 is provided with a bushing groove 41, which is hexagonal in shape and is used to accommodate the rotating shaft 5.

[0021] Specifically, the bushing groove 41 is hexagonal in shape, which is used to fully or partially accommodate the rotating shaft 5. The rotating shaft 5 is designed in the shape of a hexagonal prism, so that the rotating shaft 5 is precisely embedded in the bushing groove 41, cannot be dislodged, and cannot be moved.

[0022] In some embodiments, the upper end of the rotating shaft 5 is provided with a limiting groove 51 for connecting the grinding head 6. The rotating shaft 5 is designed in the shape of a hexagonal prism for connection with the bushing 4.

[0023] Specifically, the upper end of the rotating shaft 5 is provided with a grinding head 6, the lower end of the grinding head 6 is provided with a limiting post 61, and the upper end of the rotating shaft 5 is provided with a limiting groove 51. The limiting post 61 is partially or completely embedded in the limiting groove 51, allowing it to rotate but not detach. The rotating shaft 5 is designed in the shape of a hexagonal prism, so that the rotating shaft 5 fits precisely into the bushing groove 41. The bushing groove 41 is hexagonal, preventing the rotating shaft from detaching from the bushing and making it unable to move.

[0024] In some embodiments, the lower end of the grinding head 6 is provided with a limiting post 61, which is partially or completely embedded in the rotating shaft 5.

[0025] Specifically, the upper end of the rotating shaft 5 is provided with a grinding head 6, the lower end of the grinding head 6 is provided with a limiting post 61, and the upper end of the rotating shaft 5 is provided with a limiting groove 51. The limiting post 61 is partially or completely embedded in the limiting groove 51, and can only rotate but cannot be disengaged.

[0026] In summary, the armor grinder provided by this utility model features an integrated structure of a bushing and a bearing, comprising a body 1, a motor 2 housed within the body 1, a bearing 3 at the top of the motor 2, a bushing 4 housed within the bearing 3, and the bearing 3 and bushing 4 are integrally formed. A rotating shaft 5 is housed within the bushing 4, and a grinding head 6 is located at the upper end of the rotating shaft 5. This design optimizes the structure and significantly improves concentricity, resulting in lower vibration and noise. The integrated forming of the bearing 3 and bushing 4 optimizes components, simplifies assembly, reduces the failure rate, ensures long-term high-speed stability, and reduces eccentric wear, thereby meeting user needs.

[0027] The embodiments described above are merely illustrative of one or more implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent.
