Description

(1) Technical field

[0001] The invention relates to a robot, in particular to a repair robot used for repair operations such as welding and grinding of turbine blades in power stations. (2) Background technology

[0002] Hydroelectric power generation is widely used. After a certain period of operation, hydro turbines will have different degrees of cavitation and abrasion, which requires regular maintenance. At present, blade repair usually adopts methods such as manual repair welding and manual grinding, which often involve heavy workload, poor working environment, high strength, and low efficiency. The shape of the blade after manual grinding is difficult to match the original design shape, and the quality is poor. At present, most domestic and foreign turbine blade repair robots are in series structure. Although they can meet the requirements of the working degree of freedom, the rigidity of the mechanical system is poor, and the mechanical structure cannot undertake larg...
