Description

Technical Field

[0001] The invention relates to the technical field of laser cladding processing equipment, and in particular to the design of a laser cladding hydraulic control system based on a six-degree-of-freedom motion platform. Background Art

[0002] Laser cladding technology is a cutting-edge surface engineering process. Its core is to use a high-energy-density laser beam to quickly heat and melt a specific cladding material, and then evenly spread it on the surface of the substrate to generate a high-quality coating that is closely metallurgically bonded to the substrate. In the laser cladding process, the precise control capability of the six-degree-of-freedom motion platform is crucial. It not only ensures a strong metallurgical bond between the cladding layer and the substrate, but also effectively avoids thermal stress concentration and deformation problems during the cladding process, thereby greatly improving the reliability and service life of the cladding parts.

[0003] The six-degree-of-freedom motion platform, as a parallel mechanism with omnidirectional motion capabilities, can achieve flexible motion of six degrees of freedom in three-dimensional space by finely controlling the telescopic length of its six actuators. The platform has excellent rigid structure, strong load-bearing capacity, high-precision control performance and fast response speed. The hydraulic control system is a system that uses liquid pressure energy to transmit and control energy. In the laser cladding hydraulic control system of the six-degree-of-freedom motion platform, the hydraulic control system is mainly responsible for driving the movement of the six-degree-of-freedom motion platform.

[0004] Considering that during the laser cladding process of the existing six-degree-of-freedom motion platform, when the hydraulic rod is in an extended state for a long time and bears a large load or the hydraulic pipeline is ruptured, the hydraulic rod is prone to short-distance displacement, which causes the position of the motion platform to shift and shake, and then causes the cladding position to deviate during the laser cladding process, resulting in reduced laser cladding effect and work efficiency.

In addition, the clamping mechanism can conveniently position and clamp the laser cladding workpiece and realize the rotation effect of the table, thereby improving the workpiece position adjustment efficiency of the laser cladding and avoiding the position of the laser cladding workpiece to shift during the movement of the table.
