A bidirectional threaded rod 54 is rotatably connected to the top wall between the two vertical plates through a bearing. The bidirectional threaded rod 54 is threadedly connected to the moving block 53. A slide rail rod 2 is fixedly provided on the bottom wall between the two vertical plates, and the slide rail rod 2 is fixedly connected to the moving block 53. A motor 3 is fixedly provided at the end of the bidirectional threaded rod 54. Fixed blocks 55 are threadedly connected to both sides of the bidirectional threaded rod 54. The bottom of the fixed block 55 is slidably matched with the slide rail rod 2. A cylinder 2 56 is fixedly provided on the top of the fixed block 55. A transfer plate 57 is fixedly provided on the top of the cylinder 2 56. The two transfer plates 57 are symmetrically arranged relative to the midline of the moving block 53. Friction stripes are fixedly provided on the outer walls of the two transfer plates 57 to increase friction. It should be noted that the two transfer plates 57 are driven by the motor 3 to move closer to each other and to limit and fix the spiral air duct.

[0020] Combining Example 1 and Example 2, it can be seen that the present invention improves the quality of pipe end treatment by flushing and cleaning the pipe end in the early, middle and late stages of the pipe end grinding treatment, preventing debris from splashing into the pipe interior and keeping the inner and outer walls of the pipe clean and relatively dry.

[0021] The working process and principle of the present invention are as follows: The spiral duct produced by the spiral duct machine 1 is first cut to a fixed length by the cutting machine 2, and then transferred to the conveying member 3. The two transfer plates 57 are driven by the motor 3 to move closer to each other and limit and fix the spiral duct. Then, the motor 2 controls the threaded rod 1 51 to rotate, so that the spiral duct moves to between the two groups of processing mechanisms 4, so that the spiral duct, the connecting column 48 and the grinding ring 47 are on the same axis. Next, the air cylinder 41 is controlled to extend for the first time, so that the output ends of the plurality of flushing pipes 412 face the end of the spiral air duct. At this time, the grinding ring 47 does not contact the end of the spiral air duct. Then, the power of the water pump 420 is controlled to be the first gear, so that the water in the water tank 421 enters the delivery cavity through the elastic hose 422 and the connecting pipe 413 in turn, and is finally discharged through the plurality of flushing pipes 412 to flush and clean the impurities at the end of the spiral air duct, so as to avoid the end of the pipe being affected by the impurities during grinding, which affects the grinding quality and efficiency, and the end of the pipe is preliminarily derusted; Next, the power of the water pump 420 is controlled to the second gear, the water pressure in the connecting pipe 413 and the delivery chamber increases, and the water pressure squeezes the piston rod 418, so that water enters the annular groove 414 through the connecting groove 419 and the delivery pipe 415, and the annular airbag 411 is quickly filled. When the annular airbag 411 just contacts the inner wall of the spiral air duct, the cylinder 1 41 is controlled to extend for the second time. During this process, the annular airbag 411 moves into the spiral air duct and is tightly attached to the inner wall of the duct, and the grinding ring 47 contacts the end of the spiral air duct. The control motor 1 makes the gear 46 drive the gear ring 45 to rotate, and the connecting plate 43 drives the grinding ring 47 to grind the end of the spiral air duct to remove rust and burrs to ensure the flatness of the end of the spiral air duct. During this process, the output end of the flushing tube 412 is directed toward the inner wall of the end of the spiral air duct to cool it down to avoid the heat generated during the grinding process affecting the quality of the end of the spiral air duct. At the same time, the annular air bag 411 is always in close contact with the inner wall of the spiral air duct to avoid the debris from splashing into the interior of the spiral air duct during the grinding process, thereby ensuring the quality of the spiral air duct after grinding. After the grinding is completed, the cylinder 41 shrinks to the initial position. During this process, the annular airbag 411 is pulled outward to scrape the grinding debris and water inside the spiral air duct out of the spiral air duct, thereby ensuring the relative cleanliness of the inner wall of the duct. At the same time, the water discharged from the flushing pipe 412 flushes the surface of the grinding ring 47 to prepare for the next grinding. Next, the air cylinder 41 is controlled to contract again, and the ball 23 on the top of the connecting rod 21 cooperates with the limit ring 25 to squeeze the connecting rod 21, and the sponge at the bottom of the scrubbing plate 22 contacts the side wall of the end of the spiral air duct. The connecting plate 43 is controlled to rotate again, so that the sponge continuously wipes and cleans the side wall of the end of the spiral air duct. The present invention prevents grinding debris from entering the inner wall of the spiral air duct through the annular air bag 411, and cleans the outer wall of the spiral air duct through the sponge, thereby improving the quality of the spiral air duct after grinding.
