[0026] like Figure 4As shown, the moving component 16 includes a screw rod 161, and the mounting box 151 is symmetrically provided with bearings at the front and rear ends. The inner ring of the bearing on the mounting box 151 is fixedly connected to the smooth section of the screw rod 161, and the two screw rods 161 have opposite textures; a nut 162, a nut 162 is embedded in the middle of the straight slide 153, and the nut 162 is screwed with the adjacent screw rod 161; a rocker 163, and a rocker 163 is provided at the front end of the front screw rod 161; a coupling 164, and the two screw rods 161 are connected through the coupling 164.

[0027] like Figure 1 As shown, it also includes a chassis 19, which is installed on the machine tool housing 1 by bolt connection, and the left and right side walls of the chassis 19 are symmetrically provided with square openings 20, and the square openings 20 are located on one side of the two guide rollers 6; a sliding door 21, the front and rear side walls of the chassis 19 are both slidably provided with sliding doors 21, and the sliding door 21 is made of transparent material, which is convenient for the staff to observe the internal conditions; an exhaust fan 22, and the exhaust fan 22 is embedded on the top of the chassis 19; a pipe 23, and the air outlet of the exhaust fan 22 is connected to the pipe 23.

[0028] When the oxide scale or surface cracks on the surface of the H-shaped steel need to be polished, the staff will pass the H-shaped steel through the square opening 20 on the right side of the chassis 19. The staff opens the sliding door 21, rotates the first turntable 14, and the first screw 13 drives the sliding frame 12 to slide downward until the wire wheel of the upper main polishing assembly 10 contacts the top of the H-shaped steel. The staff then starts the servo motor 9, and the servo motor 9 rotates to drive the left conveying roller 4 to rotate counterclockwise. There is a set of conveying assemblies 8 between the left conveying roller 4 and the middle conveying roller 4, and between the middle conveying roller 4 and the right conveying roller 4, so that the three conveying rollers 4 can gradually convey the H-shaped steel to the left. Since the conveying roller 4 is slidably installed in the slide groove of the U-shaped mounting block 3, under the elastic action of the first elastic member 7, the guide roller 6 can be kept in close contact with the H-shaped steel and can rotate accordingly with the transmission of the H-shaped steel, playing a guiding and limiting role, which is suitable for H-shaped steels of different thicknesses.The staff starts the motor of the main grinding assembly 10, and the motors of the two main grinding assemblies 10 drive the wire wheels to grind the top and bottom surfaces of the H-shaped steel. When the H-shaped steel is transmitted to the position of the corner grinding assembly 1510, the servo motor 9 is first controlled to stop working, and then the staff rotates the rocker 163, and the rocker 163 drives the screw rod 161 to rotate, and then the nut 162 rotates along the screw rod 161. Since the two screw rods 161 have opposite textures, they can drive the straight slide plate 153 to move towards each other, and the middle grinding assembly 156 and the corner grinding assembly 1510 are The wire wheel fits the front and rear side walls of the H-shaped steel, and then the staff rotates the second turntable 1593, which drives the second screw 1592 to rotate. The second screw 1592 moves to the right, which drives the sliding plate 155 and the middle grinding assembly 156 to move to the right. The sliding plate 155 drives the wedge-shaped top block 1596 and the straight top block 1597 to move to the right through the connecting plate 1594. Since the bottom of the H-shaped steel contacts the conveying roller 4 during the transmission process, the wire wheel of the lower corner grinding assembly 1510 can be quickly moved by the straight top block 1597. The second elastic member 1511 is compressed, and the length of the second screw 1592 moving right is adjusted according to the height of the H-shaped steel to be ground. Since the inclined surface of the wedge-shaped top block 1596 is higher on the left and lower on the right, the semi-arc guide block 1595 can be quickly squeezed to move upward, and the wire wheel of the corner grinding assembly 1510 on the upper side is quickly squeezed to contact the right angle position of the upper side of the H-shaped steel. Since the wire wheel of the middle grinding assembly 156 and the wire wheel of the corner grinding assembly 1510 have overlapping areas, the wire wheel of the middle grinding assembly 156 and the wire wheel of the corner grinding assembly 1510 are The wheel is made of wire winding and has a certain hardness and toughness. When the wire wheel rotates, the wire on it will scrape and grind the surface to remove rust and dirt. Therefore, the wire on the outer periphery of the wire wheel cylinder and the wire at the end of the cylinder can be used for grinding and rust removal. Therefore, when the wire wheel of the edge grinding assembly 1510 is adjusted to contact the right-angle top and right-angle bottom of the H-shaped steel, the grinding area of ​​the three wire wheels still covers the entire front and rear sides, and then the servo motor 9 is continued to be started. All surfaces of the H-shaped steel transmitted to the left can be polished and completed, and there is no need for face grinding. During the grinding process, the sliding door 21 is closed to form a relatively closed space. The dust generated by grinding can be extracted by starting the exhaust fan 22, and connected to the external pipe through the pipe 23 for subsequent treatment. The device is simple to operate and can quickly adjust the position of each grinding component according to the different batch sizes of H-shaped steel, so that the wire wheel contacts each surface, and finally quickly completes the grinding and rust removal operation.
