[0037] Working principle:

[0038] When in use, the air guide cover is matched with the limit block 13 on the welding platform 1 to fix the air guide cover. At this time, the second slide bar 23, under the action of the second spring 28, drives the outer grinding frame 20 and makes the first roller 19 abut against the upper surface of the air guide cover and make it roll contact. Since the width of the air guide cover is greater than the distance between the two rolling balls 18, when the air guide cover is placed between the two rolling balls 18, the two outer grinding frames 20 move away from each other; the first slide bar 16 slides on the slider 29, thereby making the first The spring 30 contracts, so that the ball 18 always presses against the side surface of the air guide cover and makes it roll and contact. Under the action of the elastic telescopic rod 15, the second roller 17 presses against the inner surface wall of the air guide cover. At this time, the first cylinder 2 and the second cylinder 5 are started and the external grinder 21 and the internal grinder 26 are started at the same time. The second cylinder 5 drives the slide bar 11 to slide in the slideway 6. The sliding of the slide bar 11 drives the upper end of the external vertical mounting frame 3 to move, and then drives the external grinding frame 20 to move, so as to realize the grinding of the entire air guide cover.

[0039] When the first roller 19 contacts the curved surface of the air guide cover, the output end of the first cylinder 2 drives the slider 29 to slide downward in the outer vertical mounting frame 3 so that the first roller 19 always contacts the outer wall of the air guide cover. At the same time, the slider 29 presses down the airbag 4 when sliding downward along the outer vertical mounting frame 3. The air in the airbag 4 is discharged from the blowing hose and blows out the weld position being grinded by the external grinder 21. While blowing away the grinding debris, it also cools down the grinding position, thereby improving the quality of weld grinding.

[0040] The sliding of the slide bar 11 drives the toothed plate 32 to move, thereby driving the first gear 9 to rotate. The rotation of the first gear 9 drives the shaft rod 7 to rotate. The rotation of the shaft rod 7 drives the second gear 10 to rotate. The rotation of the second gear 10 drives the semicircular gear 14 meshing therewith to rotate, thereby driving the elastic telescopic rod 15 to rotate around the inner wall of the welding platform 1. When the slide bar 11 slides left and right driven by the second cylinder 5, the semicircular gear 14 is driven to rotate intermittently through the second gear 10, thereby making the elastic telescopic rod 15 swing periodically. At the same time, it can drive the second roller 17 to be able to press against the inner wall of the air guide and roll under the action of the elastic telescopic rod 15, and grind the weld on the inner surface wall of the air guide cover under the action of the internal grinder 26.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
