[0004] The above device has the following defects: relatively large block objects cannot be placed in the annular heating device, so it cannot meet the heating needs of block materials, and a certain amount of dirt remains on the surface of the workpiece before heating, resulting in preheating efficiency. Therefore, a preheating device for laser cladding processing is proposed to solve the above problems. Utility Model Content

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, by setting up structures such as active rollers, driven rollers, annular disks, and movable frames, when laser cladding workpieces of different sizes, multiple devices can simultaneously perform wiping, cleaning, and heating operations, thereby improving the preheating efficiency to a certain extent. At the same time, it improves the problem that relatively large block objects cannot be placed in the annular heating device, thereby failing to meet the heating requirements of the block materials, and a certain amount of dirt remains on the surface of the workpiece before heating, resulting in preheating efficiency problems.

[0016] 2. In the present invention, by setting up structures such as slideways, springs, and arc-shaped tooth plates, different-sized workpieces for laser cladding can be directly placed and strain-clamped to fix them.
