Laser To Create Three-dimensional Motion Beam Head

The laser remanufacturing technology is a new concept of advanced refabrication technology which combines mechanical engineering, optics, NC, electron, computer, sensor technology, material and other subjects with laser cladding.The technology not only repairs the part ,but also makes the quality better than it was before.As an important composition of laser remanufacturing technology, the laser beam coaxial powder feeding system plays a significant part especially in repairing irregular shape parts. But present laser beam coaxial powder feeding system can't satisfies the requirement of Laser remanufacturing technology, so, according to laser fabrication theory, a new 3D laser beam coaxial powder feeding system was designed.Under the control of the motor controller which is made up of microprocessor units, two stepping motors fixed on the 3D laser beam coaxial powder feeding system get the system rotating around axial z from 0° to 360°and swinging around axial x from -60°to + 60°,With the linear moving along axial z of Siemens NC system, the 3D laser beam coaxial powder feeding system can overcome the limitations of working space. It was used to repair parts especially irregular shape parts, such as crank shaft, screw, vane and so on.A new model was designed and carried out with locomotion emulate.The analysis between the laser beam coaxial powder feeding system and the new model was carried out by Microsoft of Ansys.In order to test the quality of the 3D laser beam coaxial powder feeding system, lots of experiments were carried out, included basic experiments and industry application experiments. By taking basic experiences, we got the conclusion that the 3D laser beam coaxial powder feeding nozzle was able to swing around axial x and rotate around axial z, and we got the Ideal parameters of of the system in laser cladding. Industrial applications experiments included laser quenching and laser cladding which on the screw and other irregular shape parts. The effect of experiments is good .We got the conclusion that it satisfied the requirement of Laser remanufacturing technology, solved the problem of repairing in irregular shape parts.
