Description

Technical Field

[0001] The utility model relates to the technical field of laser cladding heads, in particular to a laser cladding head component with adjustable cladding trajectory. 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 substrate and using a high-energy-density laser beam to melt it together with a thin layer on the surface of the substrate.

[0003] The utility model patent with announcement number CN210215546U discloses a laser cladding head. For the existing laser cladding working head, the powder feeding nozzle is mostly partially water-cooled or directly uses a copper tube to feed the powder to the laser focus, which is prone to uneven powder feeding and powder blocking the powder feeding port. The powder utilization rate is also greatly reduced, thereby affecting the cladding process. In addition, the lifting and lowering adjustment process of the laser cladding head is not accurate and efficient enough, and it does not have the function of ranging. The installation operation of the laser cladding head is also cumbersome and complicated, which is extremely inconvenient. Therefore, it is easy to install, easy to adjust the height, and has the function of ranging. It can also realize laser cladding of different light plates and different focal lengths, avoiding the situation of uneven powder and clogging of the powder feeding port during the powder feeding process.

[0004] In the existing use of the cladding head, it is not convenient to flexibly adjust the position of the cladding head on the processing plate according to the object to be processed, so the object needs to be moved manually. If the object is moved frequently, the accuracy of the laser cladding work will be reduced, thereby reducing the fineness and qualified rate of the laser cladding work and reducing the work efficiency. After the cladding head has been used for a long time, the performance of the cladding head has been reduced, and it needs to be disassembled, replaced and reinstalled. The existing cladding head is usually installed by welding and tightening bolts, which makes the installation and disassembly time longer, delays the work progress and prolongs the working time.

Then, the cladding head body 20 is replaced, and the replaced cladding head body 20 drives the fixing block 21 to be inserted into the inner side of the mounting shell 14. The operation is repeated to drive the clamping rod 19 with the fixing rod 18 to be clamped into the inner side of the connecting groove 22 in the middle of the fixing block 21 and the mounting shell 14. Under the pulling of the tension spring 15, the clamping rod 19 and the connecting groove 22 are more tightly engaged, thereby enhancing the stabilizing effect.
