[0042] The implementation principle of the port deburring device for fin tube processing according to the embodiment of the present invention is as follows: first, the fin to be processed is pushed on the ground to roll to the support plate 12 at the feed port 2, and the two ends of the fin tube are above the support plate 12.

One end of the driving rod 14 slides in the first driving groove 13 of the reciprocating plate 10, and the driving rod 14 squeezes the groove wall of the first driving groove 13, driving each group of two reciprocating plates 10 to move towards each other, and the supporting plate 12 is pushed up by the curved plate 11, thereby automatically lifting the fin tube to the position to be processed, and as the pulling cylinder 5 continues to move, the pulling cylinder 5 is inserted into the fin tube to be fed, and the pulling cylinder 5 drives the cross plate 24 to move on the driving ring 23, and the driving ring 23 is used to press the second driving groove The extrusion of the groove wall 25 automatically pushes the holding plate 21 out of the slot 20, and the holding plate 21 is pressed against the inner wall of the fin tube to push the fin tube to be fixed. The movement of the reciprocating plate 10 drives the two shielding covers 47 to be assembled to the end of the fin tube. During the deburring process, the generated debris is shielded to improve the working environment quality. Then, the rotating wheel 33 drives the screw sleeve 34 to rotate in the annular groove 26, driving the moving cylinder 52 to move in the annular groove 26. This drives the deburring disk 29 to fit against the fin tube port, and starts the cylinder 36 on the second mounting plate 35, driving the moving ring 37 to move toward the side close to the abutment seat 6, and rotates the handle 40 through the driving bar 43 and the third gear 42, and opens the handle 40 and the elastic cloth 41 as a whole. Finally, start the second motor 31 on the first mounting plate 30, and drive the deburring disk 29 to rotate through the first gear 32 and the second gear 51, so that the deburring processing of the fin tube port can be achieved.
