[0024] In the prior art, all the processes of the device are concentrated together and not partitioned, which results in low work efficiency. In the utility model, first, the gear to be polished is placed on the placing base 3 of the placing area on the fixed circular table 2. The fixed circular table 2 has a rotating function and can move the gear on the placing base 3 to different working areas in turn. When the fixed circular table 2 rotates, the gear on the placing base 3 is first transferred to the first polishing area, where the first polishing mechanism 4 is installed, which is used for polishing the front surface of the gear to be polished. After the first polishing, the fixed circular table 2 continues to rotate and transfers the gear from the first polishing area to the turning area. In the turning area, there is a second motor 11, the output shaft of which is connected to an extension rod 12, and the other end of the extension rod 12 is connected to a moving box 13. The moving box 13 is internally provided with a clamping mechanism 14 for clamping the gear to be processed on the placing base 3. When the clamping mechanism 14 clamps the gear, the second motor 11 drives the moving box 13 to move upward through the extension rod 12. The moving box 13 is fixedly connected with a rotating disc 15 outside, and the back surface of the rotating disc 15 is provided with a second rack 151. The second rack 151 is internally provided with a second gear 16, which is engaged with the second rack 151. The second gear 16 is connected to a fourth motor 17, which is located inside the moving box 13 and outside the rotating disc 15. The fourth motor 17 is used for driving the second gear 16 to rotate, thereby driving the rotating disc 15 to turn over through the second rack 151. The turning over of the rotating disc 15 drives the clamping mechanism 14 to turn over, and the turning over of the clamping mechanism 14 drives the gear to be processed to turn over, thereby realizing the turning over of the gear. After the turning over is completed, the fixed circular table 2 rotates again to transfer the gear on the placing base 3 to the second polishing area. The second polishing area is provided with a second polishing mechanism 5, which is used for polishing the back surface of the gear to be processed. Through such an automatic process, the polishing and polishing machine can efficiently and accurately complete the double-sided polishing and polishing work of the gear.

[0025] Referring to Figures 1-5 : The clamping mechanism 14 comprises a third motor 141, a first gear 142, first and second clamping blocks 143 and 144, and a first rack 145, the third motor 141 is fixedly connected with the first gear 142, the first and second clamping blocks 143 and 144 are fixedly connected with the first rack 145, the first gear 142 is engaged with the first rack 145 on the first and second clamping blocks 143 and 144, and the first gear 142 drives the first and second clamping blocks 143 and 144 to move closer to or away from each other when rotating.

[0026] The clamping mechanism 14 is responsible for stably clamping the gear to be processed during the turning process. The clamping mechanism 14 includes a third motor 141, a first gear 142, a first clamping block 143, a second clamping block 144, and a first rack 145 arranged in the moving box 13. The first clamping block 143 and the second clamping block 144 are the two main parts of the clamping mechanism 14, and they are respectively fixedly connected with the first rack 145. The design of the first rack 145 allows them to move linearly under the rotation of the gear. When the first gear 142 rotates, it drives the first clamping block 143 and the second clamping block 144 to move along the rack through the meshing first rack 145, thereby realizing the mutual approach or away of the two. This design enables the clamping mechanism 14 to drive the first gear 142 to rotate by driving the third motor 141 when the gear needs to be turned, thereby bringing the first clamping block 143 and the second clamping block 144 closer to the gear to clamp the gear. During the turning process, the clamping mechanism 14 keeps the gear stable, ensuring that the gear can be accurately turned to the desired position. After the turning is completed, the first gear 142 can be reversed to rotate, causing the first clamping block 143 and the second clamping block 144 to move away from the gear, releasing the clamping, so that the gear can continue the subsequent polishing process. Through this automatic clamping and releasing mechanism, the polishing machine can efficiently and accurately handle the turning and processing of the gear.

[0027] Referring to Figure 1 and Figure 2 The upper surface of the moving box 13 is fixedly connected with a guide rod 18, and the top of the turning area is provided with a guide hole 19. The guide rod 18 is inserted into the guide hole 19, and through the cooperation of the guide rod 18 and the guide hole 19, the moving box 13 will not deviate during movement.

[0028] The upper surface of the moving box 13 is fixedly connected with a guide rod 18, and the top of the turning area is provided with a guide hole 19. The main purpose of this design is to ensure the stability and accuracy of the moving box 13 during vertical movement, preventing deviation during movement.

[0029] Referring to Figure 2 A first motor 21 is arranged below the fixed circular table 2, and the first motor 21 is used to drive the fixed circular table 2 to rotate.

[0030] A first motor 21 is arranged below the fixed circular table 2, and the main function of this first motor 21 is to drive the fixed circular table 2 to rotate. The fixed circular table 2 is one of the core components of the polishing machine, which carries the placing base 3 and the gear to be processed, and rotates to transfer the gear from one working area to another.

[0031] Referring to Figure 2The fixing clamping base 31 is arranged on the placing base 3 and is used for limiting the gear to be machined, so that the gear to be machined is prevented from rotating during polishing.

[0032] When the gear to be machined is placed on the placing base 3, the gear is fixed by the limiting structure of the fixing clamping base 31. In this way, during the rotation of the fixing circular table 2 and the transfer of the gear on the placing base 3 to each polishing area, the gear will not rotate due to the rotation force or other external forces. This fixing mode ensures the stability of the gear during polishing and polishing, so that the polishing mechanism can accurately polish the predetermined surface of the gear. Through the limiting action of the fixing clamping base 31, the polishing and polishing machine can ensure the accurate positioning and stability of the gear during processing, thereby improving the quality and efficiency of polishing and polishing.

[0033] Reference Figure 2 The first polishing mechanism 4 and the second polishing mechanism 5 comprise a rotating machine 6, and the output shaft of the rotating machine 6 is fixedly connected with a polishing piece 61.

[0034] The output shaft of the rotating machine 6 is fixedly connected with the polishing piece 61. When the rotating machine 6 is started, it generates a rotation force through the built-in motor, which is transmitted to the output shaft, and then drives the polishing piece 61 fixed on the output shaft to rotate at high speed. These polishing pieces 61 are usually made of wear-resistant materials and have special textures or shapes suitable for polishing the surface of the gear to adapt to different polishing requirements. In the first polishing area, the rotating machine 6 of the first polishing mechanism 4 drives the polishing piece 61 to polish the front surface of the gear, removing burrs, unevenness or other surface defects. Similarly, in the second polishing area, the rotating machine 6 of the second polishing mechanism 5 also drives the polishing piece 61 to polish the back surface of the gear. Such a design enables the machine to automatically complete the double-sided polishing and polishing of the gear, improving production efficiency and processing quality. The rotation speed and force of the polishing piece 61 can be adjusted according to the gear material and polishing requirements to ensure that the polishing effect meets the process standards. The stability of the rotating machine 6 and the precise control of the output shaft are crucial to ensure the quality and efficiency of polishing and polishing. The entire polishing and polishing process is automated, reducing manual operation, improving production efficiency and operation safety.
