The frame 6 rotates by engaging with the outer thread of the adjusting screw rod 403 through the thread groove 601, driving the two pairs of pressing frames 6 to slide in opposite directions on the inner side of the slide groove B402 through the slider, and contact the H-shaped steel around to limit the H-shaped steel, then release the adjusting disk 406 to make the damping telescopic rod B407 and the outer spring contract the adjusting disk 406, driving the limit block B408 to slide into the inner side of four of the relative limit grooves B409, and the staff adjusts the two pairs of pressing frames 6 in the other storage slot 401 in the same way, and after fixing the H-shaped steel limit, the staff controls the hydraulic rod 3 to lower the feeding frame 301, and at the same time controls the two servo motors B5 to drive the outer ring chain of the rotating frame 501 to drive the rotating bracket 4 to rotate through the bearing, and adjust the H-shaped steel to the appropriate inverted After the angle is processed, the staff controls the screw slide A102 and the screw slide B104 to drive the grinding head 109 to move to the required processing position through the slider, and then controls the electric telescopic rod 106 to lower the grinding head 109 to contact the welding part of the H-shaped steel, and turns on the servo motor A108 to drive the grinding head 109 to rotate, and performs chamfering and grinding on the welding part of the H-shaped steel. Finally, the staff controls the hydraulic rod 3 to raise the feed rack 301 to contact the bottom of the H-shaped steel, and releases the four pairs of two pairs of pressing racks 6 in the same way. After that, the staff controls the hydraulic rod 3 to lower the feed rack 301 to drive the H-shaped steel to lower. After that, the staff drives the forklift to drive the fork in front to pass through the middle groove of the "U"-shaped feed rack 301, and then controls the hydraulic rod 3 to lower the feed rack 301 again.After the H-beam contacts the fork surface, the staff drives the forklift to carry the chamfered H-beam to other processing sites.
