Description

Technical Field

[0001] The utility model relates to the technical field of supporting devices, in particular to a supporting device for laser repair based on laser cladding. Background Art

[0002] Laser cladding, also known as laser melting or laser cladding, is a new surface modification technology. It forms a metallurgically bonded cladding layer on the surface of the base 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.

[0003] After searching the patent document with the announcement number CN219603690U, the distance and height between the two adjusting rollers are adjusted by the support mechanism according to the diameter of the rod, so as to support the middle position of the rod, and the height of the three-jaw chuck is adjusted by the servo motor and the lead screw, and then one end of the rod is fixed by the three-jaw chuck;

[0004] In the patent document, one end of the rod is fixed by a three-jaw chuck, and the diameter of the cylinder that can be clamped by the three-jaw chuck is limited. In the above structure, if only one end is clamped and fixed, and the middle position of the rod is supported, the unfixed end of the entire rod will swing during the rotation, which will cause the melted cladding material to be shaken off during the laser cladding repair. In addition, since one side of the rod is at high temperature and the other side is at low temperature, and the vibration caused by the swinging of the end of the rod, the rod after the cladding repair may bend. At the same time, when installing the rod, it is necessary to adjust the entire support mechanism to make the axis of the rod consistent with the axis of the three-jaw chuck, so it is very inconvenient to install the rod quickly.
