The ring 13 is internally slidably connected to a fixed rod 14, the lower part of the fixed plate 11 is fixedly connected to a carrier frame 16, the inside of the carrier frame 16 is fixedly connected to a motor 17, and the output end of the motor 17 is fixedly connected to a grinding disc 18; the clamping assembly includes a fixed frame 4, the fixed frame 4 is fixedly connected to the upper side of the filter plate 3, the inside of the fixed frame 4 is fixedly connected to evenly distributed telescopic rods 5, the outside of the telescopic rods 5 is provided with a spring 6, the output end of the telescopic rod 5 is fixedly connected to a clamping plate 7, and an anti-slip pad 8 is provided on the adjacent side of the clamping plate 7.

[0030] By placing the elbow on the upper side of the filter plate 3, the clamping plate 7 generates a reaction force during the clamping process of the elbow, squeezes the telescopic rod 5 and the spring 6, and the anti-slip pad 8 plays an anti-slip role. By starting the hydraulic rod 10, the fixed plate 11, the connecting block 12 and the ring 13 are driven to move, so that the ring 13 slides on the outside of the fixed rod 14. At the same time, the movement of the fixed plate 11 drives the carrier frame 16 to move, and the grinding disc 18 is driven to rotate by starting the motor 17, which plays a role in clamping the elbow to prevent movement or shaking during the polishing process, and can automatically adjust the mechanism.

[0031] Reference Figure 1 , Figure 2 An exhaust fan 20 is fixedly connected to the inside of the workbench 1, an intake pipe 21 is fixedly connected to the input end of the exhaust fan 20, a collecting box 22 is fixedly connected to the left end of the intake pipe 21, a slide groove 23 is provided inside the collecting box 22, a cleaning component is slidably connected to the inside of the slide groove 23, and a conveying pipe 19 is fixedly connected to the upper side of the cleaning component; the cleaning component includes a sliding block 24, the sliding block 24 is slidably connected to the inside of the slide groove 23, a filter screen 25 is arranged on the adjacent side of the sliding block 24, and a pull rod 26 is fixedly connected to the front side of the filter screen 25.

[0032] By starting the exhaust fan 20, the suction pipe 21, the collection box 22, and the conveying pipe 19 are used to absorb the inside of the groove 2. The debris generated during polishing enters the conveying pipe 19 and the collection box 22 from the inside of the groove 2, and falls to the upper side of the filter 25. The gas enters the exhaust fan 20 from the inside of the suction pipe 21 and is discharged. When the filter 25 is blocked, the pull rod 26 is manually pulled to drive the filter 25 and the sliding block 24, so that the sliding block 24 slides in the slide groove 23, thereby collecting the debris generated during the polishing process.

[0033] Reference Figure 1 , Figure 2 , Figure 3 The fixing rod 14 is fixedly connected to the upper side of the inner part of the support frame 9, and the bottom end of the fixing rod 14 is fixedly connected to the limiting block 15; the filter screen 25 is slidably connected to the inside of the collecting box 22; the clamping plate 7 is slidably connected to the inside of the fixing frame 4; the collecting box 22 is fixedly connected to the inside of the workbench 1.

The clamping plate 7 generates a reaction force during the clamping process to squeeze the telescopic rod 5 and the spring 6. The anti-slip pad 8 is set to play an anti-slip role during the clamping process. By starting the hydraulic rod 10, the hydraulic rod 10 starts to drive the fixed plate 11 to move, and the movement of the fixed plate 11 drives the connecting block 12 to move. The movement of the connecting block 12 drives the ring 13 to slide on the outside of the fixed rod 14. At the same time, the movement of the fixed plate 11 drives the carrier 16 to move. By starting the motor 17, the motor 17 starts to drive the grinding disc 18 to rotate, and the inner hole of the elbow is polished, so that the elbow is clamped to prevent movement or shaking during the polishing process, and the automatic adjustment mechanism can be used to adapt to different specifications and requirements. Elbow, by starting the exhaust fan 20, the exhaust fan 20 starts to drive the suction pipe 21 for suction, the suction pipe 21 drives the collection box 22 for suction, the collection box 22 drives the delivery pipe 19 to suck the inside of the groove 2, and the debris generated during polishing falls from the inside of the filter plate 3 into the inside of the groove 2, enters the inside of the delivery pipe 19 from the inside of the groove 2, enters the inside of the collection box 22 from the inside of the delivery pipe 19, and falls to the upper side of the filter 25, the gas enters the inside of the suction pipe 21 from the inside of the collection box 22, and is discharged from the inside of the exhaust fan 20. When the filter 25 is blocked, manually pull the pull rod 26, the movement of the pull rod 26 drives the filter 25 to move, the movement of the filter 25 drives the sliding block 24 to slide in the slide 23, and the filter 25 is cleaned, thereby realizing the collection of debris generated during the polishing process to prevent the debris from causing damage to the body of the staff.
