Abstract

The utility model relates to the technical field of laser cladding processing, in particular to a laser cladding processing device for a thermocouple protective sleeve of a circulating fluidized bed boiler, which comprises a reversed-Pi-shaped bottom plate and a protective sleeve arranged on the upper part of the bottom plate, wherein a support frame is fixedly arranged on the bottom plate, an electric telescopic rod is fixedly arranged at the bottom end of the support frame, two symmetrically arranged lead screws are rotatably arranged on the bottom plate, a reversed-convex fixing plate is fixedly arranged on the outer wall of a first threaded sleeve, and two horizontally arranged bearing cylinders for placing the protective sleeve are rotatably arranged on the inner wall of the fixing plate. According to the laser cladding device, the rotation of the two bearing cylinders and the rotation of the two lead screws are adopted, so that the bearing cylinders can simultaneously and stably move in the process of rotating, the outer wall of the protection pipe sleeve can be uniformly clad by the laser head, the phenomenon that the rotation speeds of the protection pipe sleeve are different due to the fact that the protection pipe sleeve is manually rotated is avoided, and the protection pipe sleeve is uneven in the process of laser cladding is avoided.
