[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0024] refer to Figures 1 to 4As shown in the figure, a rotary table surface polishing device provided by this utility model includes a polishing box 1. The front of the polishing box 1 is hinged with a box door 101. A worktable 102 is fixedly connected inside the polishing box 1. A support platform 3 that can move up and down is installed on the top of the worktable 102. A support frame 402 is fixedly connected to the inner wall of the back of the polishing box 1. A pressure block 4 is fixedly connected to the bottom of the support frame 402. A rotary table body 2 is pressed between the support platform 3 and the pressure block 4. A polishing assembly is rotatably installed on the inner top of the polishing box 1. The polishing assembly includes a rotating plate 603 and a polishing cylinder 5. The polishing cylinder 5 is distributed in a ring array on the circumferential side wall of the rotary table body 2.
[0025] Specifically, a telescopic cylinder 302 is fixedly installed at the bottom of the grinding box 1, and a support rod 301 is fixedly connected to the output end of the telescopic cylinder 302. The upper end of the support rod 301 passes through the worktable 102 and is fixedly connected to the support table 3.
[0026] The above scheme facilitates the stable installation of the support platform 3 and enables the support platform 3 to move up and down, which in turn facilitates the up and down movement of the turntable body 2 on the support platform 3. This, in turn, makes it easier for the support platform 3 to drive the turntable body 2 to be pressed and fixed against the pressure block 4, thus facilitating stable grinding work.
[0027] Specifically, a pressure rod 401 is threadedly connected to the lower middle part of the support frame 402, and the lower end of the pressure rod 401 is fixedly connected to the pressure block 4.
[0028] The above scheme facilitates the installation of the pressure block 4, and makes it easy for the pressure block 4 and the support platform 3 to cooperate in pressing and fixing the turntable body 2 during the grinding process, ensuring grinding quality and precision, and improving grinding efficiency.
[0029] Specifically, a rotating shaft 604 is fixedly connected to the top of the rotating plate 603. The rotating shaft 604 is connected to the top of the grinding box 1 through a bearing. A motor 605 is fixedly installed on the top of the grinding box 1. The output end of the motor 605 is fixedly connected to the upper end of the rotating shaft 604. Fixing blocks 602 are fixedly connected to both ends of the bottom of the rotating plate 603. A rotating rod 6 is connected to the fixing block 602 through a bearing. The grinding cylinder 5 is threadedly sleeved on the lower part of the rotating rod 6.
[0030] The above-mentioned scheme facilitates the rotation of the rotating plate 603, which in turn drives the rotating rod 6 to rotate synchronously. This facilitates the stable installation of the grinding cylinder 5 and the rotating rod 6, thereby enabling the grinding cylinder 5 to rotate stably along the circumferential side wall of the turntable body 2. This allows for stable contact with the turntable body 2, achieving uniform grinding without the need for frequent adjustments to the grinding cylinder 5, thus improving grinding efficiency. Furthermore, it facilitates the installation and disassembly of the grinding cylinder 5, making it easy to replace and adapt to turntable bodies 2 of different sizes for grinding processing.

[0032] Using the above scheme, when the rotating plate 603 drives the rotating rod 6 and the grinding cylinder 5 to rotate along the circumferential side wall of the turntable body 2, the gear 601 meshes with the internal gear ring 7, which in turn drives the rotating rod 6 to rotate, and then drives the grinding cylinder 5 to rotate, thereby realizing the grinding operation on the circumferential side wall of the turntable body 2.
[0033] Specifically, the lower side wall of the rotating rod 6 is provided with a threaded groove 606, and the grinding cylinder 5 is threadedly connected to the threaded groove 606. The outer surface of the grinding cylinder 5 is in contact with the circumferential side wall of the turntable body 2.
[0034] The above solution facilitates the installation and disassembly of the grinding cylinder 5, and makes it easy to replace grinding cylinders 5 of different sizes. This, in turn, facilitates the fitting of the circumferential sidewalls of the turntable body 2 of different sizes, enabling stable grinding operations along the circumferential sidewalls. It offers high flexibility, wide applicability, and improved efficiency.
[0035] The working principle of this utility model:
[0036] In use, the telescopic cylinder 302 is activated to move the support platform 3 downwards until it is below the grinding cylinder 5. The turntable body 2 is then placed on the support platform 3, which continues to move upwards, securing the turntable body 2 against the pressure block 4. Next, a suitable grinding cylinder 5 is replaced according to the size of the turntable body 2, ensuring it fits against the circumferential sidewall of the turntable body 2. Then, the motor 605 is activated, and the grinding cylinder 5 rotates along the circumferential sidewall via the rotating plate 603 and rotating rod 6. Simultaneously, through the engagement of the gear 601 and the internal gear ring 7, the grinding cylinder 5 rotates synchronously, thus grinding the circumferential sidewall of the turntable body 2. This facilitates stable contact with the circumferential sidewall, achieving uniform grinding without frequent adjustments to the grinding cylinder 5, improving grinding efficiency. Furthermore, the grinding cylinder 5 is easy to install and disassemble, allowing for flexible replacement and further enhancing efficiency.
