Description

Technical Field

[0001] The utility model relates to the technical field of laser cladding, in particular to an anti-sputtering laser cladding inner nozzle. Background Art

[0002] Laser cladding technology is a new technology with high economic benefits. It can prepare high-performance alloy surfaces on cheap metal substrates without affecting the properties of the substrate, reducing costs and saving precious rare metal materials. Therefore, all advanced industrial countries in the world attach great importance to the research and application of laser cladding technology. The application of laser cladding is mainly in two aspects, namely corrosion resistance (including high temperature corrosion resistance) and wear resistance. The application range is very wide, such as the sealing surface of valves and valve seats of internal combustion engines, laser cladding of water, gas or steam separators, etc. When processing workpieces, laser cladding technology mainly uses the laser generated by the laser cladding nozzle to touch the workpiece body. The laser cladding head is mainly composed of: link components, optical components, and powder feeding components. The laser equipment is connected to the powder feeder through the laser cladding head, and the coating is quickly scanned by a high-energy laser beam. The preset powder melts and solidifies in an instant, and the base metal melts into a thin layer. The interface between the two quickly produces molecular or atomic-level cross-diffusion in a very narrow area, and at the same time forms a strong metallurgical bonding layer, thereby significantly improving the various properties of the base body such as hardness, alkali resistance and corrosion resistance.

[0003] However, the existing laser cladding heads still have the following problems during use: during the processing of the existing laser nozzles, the nozzle will touch the workpiece body, and the ejected material will splash everywhere. Therefore, some laser nozzles are assembled with anti-sputtering mechanisms, but these anti-sputtering mechanisms are easy to block the nozzles, making it impossible for the nozzles to accurately position the workpiece, which is easy to cause operational errors. Therefore, it is necessary to involve an anti-sputtering laser cladding internal nozzle for use in the existing laser cladding technology field. Utility Model Content

[0004] In order to make up for the shortcomings of the prior art, the existing anti-sputtering mechanism easily blocks the nozzle, making it impossible for the nozzle to accurately position the workpiece for processing, which easily causes the problem of operation error. The utility model proposes an anti-sputtering laser cladding inner nozzle.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an anti-sputtering laser cladding internal nozzle, including a connecting shell, the bottom of the connecting shell is fixedly equipped with a nozzle body, the bottom of the connecting shell is fixedly equipped with a plurality of vertical blocks, the vertical blocks are located on the outside of the nozzle body, connecting blocks are fixedly equipped between the vertical blocks, the sides of the connecting blocks are fixedly equipped with assembly blocks, a movable rod is movably equipped on the assembly block, both ends of the movable rod are fixedly equipped with traction blocks, and the two traction blocks are fixedly equipped with baffles.

[0011] The utility model is beneficial in that:

[0012] The utility model calibrates the nozzle body to the top of the processed workpiece.
