[0031] Working principle: First, the steel to be processed is placed on the feeding seat 301, and the limit plates 302 on both sides are squeezed so that the steel is clamped in the middle by the limit plates 302 on both sides, and the steel is fixed and limited. Then, the kinetic energy of the first motor 202 drives the threaded rod 201 to rotate, and the sliders on both sides are driven to move. Then, the lifting frame 203 is pushed up and down by the first cylinder 204, and the position of the grinding wheel 214 under the lifting frame 203 is adjusted, so that the grinding wheels 214 on both sides are moved to the welds on both sides of the H steel, and the second motor 21 3 kinetic energy, using multiple bevel gears 215 to mesh, thereby driving the grinding wheels 214 on both sides to rotate and grind the weld.

The top block 210 is slidably matched, so that the top block 210 presses the lower pressure plate 207 downward, so that the lower pressure plate 207 forms a tendency to move downward, forming a certain reaction force, thereby driving the two grinding wheels 214 under the connecting frame 212 to move downward, thereby increasing the friction between the welding seam and the pressure between them, thereby increasing the grinding force at the thicker part of the welding seam, thereby adjusting the distance between the grinding wheel 214 and the welding seam adaptively according to the thickness of the welding seam, and then adjusting the pressure between the grinding wheel 214 and the welding seam, thereby improving the grinding uniformity of the thicker welding seam. The uniformity is improved, and the grinding quality of the steel is improved. During grinding, air is blown through the two blowing pipes on the air pump 206, and the waste chips generated by the grinding are blown to the rear side along the surface of the H-shaped steel, so that they fall into the waste trough 216 for collection, thereby reducing the pollution of the surrounding environment caused by the waste chips and improving the cleaning performance of the device. After grinding, the kinetic energy of the third motor 305 drives the multiple feeding rollers 304 to rotate, and then the rotation of the multiple rollers 303 is used to transport the grinded steel to the rear side for feeding, thereby completing the grinding operation of the weld of the H-shaped steel.
