Description

Technical Field

[0002] Laser cladding, also known as laser cladding or laser melting, is a new surface modification technology. It forms a metallurgically bonded cladding layer on the surface of the base material by adding cladding material to the surface of the base material and using a high-energy-density laser beam to melt it together with a thin layer on the surface of the base material.

[0004] In the above-mentioned and prior art, during the laser cladding processing of the workpiece, the workpiece is directly placed on the workbench. However, during the laser cladding processing of the workpiece, the workpiece is prone to move, which will cause the laser cladding to be misplaced. Some laser cladding devices are also provided with an auxiliary support structure for the workpiece, but it is not convenient to rotate the workpiece, resulting in that after processing one part of the workpiece, it is necessary to dismantle the rotation and re-fix it before laser cladding processing can be performed on other processing positions of the workpiece, which is time-consuming, labor-intensive and inefficient. Therefore, it is urgent to design a laser cladding device with an auxiliary support structure to solve the above problems. Utility Model Content
