Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 1 , Figure 2 and Figure 3The utility model provides an embodiment: an automatic outer cylindrical polishing machine for elbows, comprising a workbench 1, a support frame 2 is fixedly connected to the upper surface of the workbench 1, a motor 3 is fixedly connected to the upper surface of the support frame 2, a rotating roller 4 is fixedly connected to the output end of the motor 3, a shell 5 is fixedly connected to the upper surface of the workbench 1, a transmission roller 6 is rotatably connected inside the shell 5, a belt 7 is arranged between the transmission roller 6 and the rotating roller 4, a limiting ring 9 is fixedly connected inside the shell 5, a fixed roller 8 is fixedly connected to the outer wall of the transmission roller 6, an abrasive belt 10 is arranged on the outer wall of the fixed roller 8, the outer wall of the fixed roller 8 slides on the inner wall of the limiting ring 9, an electric slide rail 2 13 is opened inside the shell 5, a connecting block 14 is slidably connected inside the electric slide rail 2 13, and a sliding component is arranged on the upper surface of the workbench 1.

[0025] Specifically, the motor 3 drives the rotating roller 4 to rotate, so that the belt 7 drives the transmission roller 6 to rotate. The transmission roller 6 rotates stably inside the shell 5 through the fixed roller 8 and the limit ring 9. The transmission roller 6 drives the fixed roller 8 to rotate, so that the sand belt 10 set on the outer wall of the fixed roller 8 can polish the outer circle of the elbow. The two wall surfaces of the transmission roller 6 are provided with sand belts 10. Double grinding can ensure the quality of processing and achieve the effect of efficient polishing.

[0026] Reference Figure 3 , Figure 4 and Figure 5 The sliding assembly includes a fixed frame 11, the lower surface of the fixed frame 11 is fixedly connected to the upper surface of the workbench 1, the upper surface of the fixed frame 11 is provided with an electric slide rail 12, the electric slide rail 12 is slidably connected to a push rod 17 inside, the output end of the push rod 17 is fixedly connected to a push plate 18, the push plate 18 is rotatably connected to a rotating rod 21 inside, the outer wall of the rotating rod 21 is rotatably connected to a clamping block 22, the clamping block 22 is rotatably connected to a fixed roller 23 inside, one end of the fixed roller 23 is fixedly connected to a connecting plate 24, the connecting plate 24 is fixedly connected to a fixed block 20 inside, the fixed block 20 is fixedly connected to a limiting rod 19 inside, the outer wall of the limiting rod 19 is slidably connected to the inside of the push rod 17, the connecting block 14 is fixedly connected to a fixed rod 15, and the fixed rod 15 is fixedly connected to a telescopic rod 16 inside.

[0027] Specifically, the telescopic rod 16 connected to the fixed rod 15 is telescopic to open the abrasive belt 10 to facilitate the elbow to enter the interior of the abrasive belt 10, thereby accelerating the polishing speed and facilitating the polishing work. The abrasive belt 10 is retracted without hindering the rotation of the abrasive belt 10. The pushing rod 17 drives the pushing plate 18 to rotate the rotating rod 21, thereby causing the clamping block 22 to rotate around the fixed roller 23. The fixed roller 23 clamps the elbow to prevent the elbow from shaking during polishing, thereby improving work efficiency. The clamping mechanism slides inside the electric slide rail 12 to avoid manual feeding and increase the safety of the processing device.

[0028] Working principle: When the automatic external circle polishing machine for elbows is needed, first, the push rod 17 sliding inside the electric slide rail 1 drives the push plate 18 to move. The movement of the push plate 18 causes the rotating rod 21 to rotate, so that the clamping block 22 rotates around the fixed roller 23, firmly clamping the elbow. Then, it drives the elbow to slide, moving the elbow to a position close to the housing 5, avoiding the trouble of manual operation, saving time, and being able to fix the elbow at the same time. During polishing, it achieves the effect of preventing the elbow from shaking, improving the working effect. Then, the connecting block 14 sliding inside the electric slide rail 2 13 moves, driving the telescopic rod 16 connected to the fixed rod 15 to extend, pulling open the inside of the abrasive belt 10 to facilitate the elbow to enter the inside of the abrasive belt 10. Then, the motor 3 drives the rotating roller 4 to rotate, so that the belt 7 drives the driving roller 6 to rotate. The fixed roller 1 8 fixed on the surface of the driving roller 6 rotates inside the limit ring 9, achieving the effect of increasing the stability of the movement of the driving roller 6. The driving roller 6 rotates to polish the elbow attached to the inner wall of the abrasive belt 10. When a part of the elbow passes through the housing 5, it is clamped by the clamping mechanism on the other side of the housing 5, completing automatic grinding and polishing, without the need for manual feeding and manual fixing of the elbow, ensuring the safety of the device during use, and achieving the effect of improving work efficiency.
