[0053] Then, the first threaded lead screw 5 can be driven to rotate by the first motor 4, the first nut seat 6 can be driven to move by the threaded lead screw 5, the Z-axis drive box 7, the Y-axis drive box 11 and the laser head 16 can be synchronously driven to move by the first nut seat 6, so that the left-right horizontal position of the laser head 16 can be adjusted through the X-axis drive box 3; meanwhile, the second threaded lead screw 9 can be driven to rotate by the second motor 8, the second nut seat 10 can be driven to move by the threaded lead screw 9, and the Y-axis drive box 11 and the laser head 16 can be synchronously driven to move by the second nut seat 10, so that the up-down horizontal position of the laser head 16 can be adjusted through the Z-axis drive box 7; meanwhile, the third threaded lead screw 13 can be driven to rotate by the third motor 12, the third nut seat 14 can be driven to move by the threaded lead screw, and the laser head 16 can be synchronously driven to move by the third nut seat 14, so that the front-rear position of the laser head 16 can be adjusted through the Y-axis drive box 11; and the left-right position, the front-rear position and the up-down position of the laser head 16 can be adjusted through the X-axis drive box 3, the Y-axis drive box 11 and the Z-axis drive box 7 respectively, so that the laser head 16 can automatically perform remelting operation on the surface of the workpiece.

[0054] Then, two laser beams can be emitted by the two laser heads 16, and are respectively cladding laser and remelting laser, so that the workpiece coated with a metal coating is first subjected to laser cladding by one of the laser heads 16 to obtain a cladding layer, and then the cladding layer is subjected to laser remelting by the other laser head 16, so that the cladding layer undergoes a rapid melting to solidification process, so that the bonding state between the coating and the workpiece surface changes from mechanical bonding to metallurgical bonding, enhancing the adhesion and stability of the coating, so that an alloyed layer can be formed on the surface of the workpiece;

[0055] Meanwhile, by sliding the sliding seat 26 on the sliding rail 24, the sliding seat 26 can drive the protective cover 25 to move synchronously, so that the two protective covers 25 can be conveniently opened and closed, so that when the protective cover 25 is closed, the entire metal remelting process can be protected from external influences, and harmful smoke and dust generated during the remelting process under the action of the laser beam can also be prevented from being dispersed everywhere, and then the smoke in the protective cover 25 can be sucked into the filter box 29 by the exhaust fan 31 in the filter box 29, and the smoke can be dispersed to the outside through the activated carbon filter plate 32, so that the activated carbon filter plate 32 can filter and adsorb harmful substances in the harmful smoke, preventing harm to the human body caused by dispersion to the outside.
