[0002] Laser cladding refers to placing the selected coating material on the surface of the cladding substrate in different ways. After laser irradiation, it and a thin layer on the substrate surface are melted at the same time, and then quickly solidified to form a surface coating with extremely low dilution and metallurgical bonding with the substrate, which significantly improves the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties of the base surface.

This cycle can continuously and rapidly cool the processed tubular workpiece, and can also be used to cool the tubular workpiece after the processing is completed.

[0026] Working principle: When the power is turned on, the tubular workpiece to be processed is placed between the two conical cylinders 6 during laser cladding processing of the tubular workpiece. The adjusting bolt 802 is rotated to move in the direction of the support block 4, so that one end of the adjusting bolt 802 pushes the support block 4 toward one end of the workpiece. After the adjusting bolt 802 is rotated into place, the conical surfaces of the two conical cylinders 6 are squeezed into the inside of the tubular workpiece to clamp and fix the tubular workpiece. Then, by starting the servo motor 701, the output end of the servo motor 701 drives the gear 702 to mesh with the toothed ring 703 on the middle surface of the adjacent conical cylinder 6, so that the clamped tubular workpiece rotates and is clad by the laser.
