Remanufacturing device for roller way roller subjected to laser cladding composite rolling

The utility model discloses a roller bed roller remanufacturing device for laser cladding composite rolling, which comprises a machine tool clamping device for clamping a roller bed to be processed from the end part; the laser cladding device, the rolling device and the turning device are located above the roller way to be machined; the laser cladding device, the rolling device and the turning device are all connected through mechanical transmission arms, and are moved through numerical control to process the roller way to be processed. When the roller surface of the roller way is repaired by the roller surface repairing device, a fine grain structure can be obtained, and the surface hardness and the wear resistance can be remarkably improved; compared with single laser cladding, the device has the advantages that cracks of a cladding layer can be effectively reduced, the cladding efficiency is improved, and large-area laser cladding surface remanufacturing can be carried out when the device is adopted for co
