Description

Technical Field

[0001] The utility model relates to the technical field of laser cladding, in particular to a laser cladding nozzle installation structure. 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 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. The existing laser cladding nozzle is cumbersome to install and disassemble, and cannot be installed and disassembled quickly, which affects the use and maintenance of the device.

[0003] For example, the patent application with application number CN212223103U includes a fixed base, the inner ring of the left shell of the fixed base is fixedly sleeved with a threaded barrel, the inner ring of the threaded barrel is rotatably sleeved with a first screw, the first screw is bolted with the threaded barrel, the inner wall of the bottom shell of the fixed base is fixedly connected with a fixed block, the top of the fixed block is fixedly connected with a spring, a clamping block is provided above the top of the spring, the front left side and the back left side of the clamping block are respectively rotatably connected to the front shell inner wall and the back shell inner wall of the fixed base, and a limiting rod is welded to the outer wall of the right shell of the fixed base.
