The invention provides an on-line
laser reinforcing device for hydraulic
turbine blades. The on-line
laser reinforcing device comprises a track, a traveling mechanism, a
robot and
laser cladding complete equipment; and the annular track is arranged in a rotating wheel chamber of a hydraulic
turbine, the traveling mechanism is arranged on the track, the
robot is connected with the traveling mechanism, the laser cladding complete equipment is connected with the
robot, the traveling mechanism is pushed to move along the track to drive the robot to arrive at the operation area, and the robot controls the laser cladding complete equipment to repair the cladding part. According to the on-line laser reinforcing device, the problems that in the traditional electric-
arc welding defect repair process of original hydraulic
turbine blades, the
heat effect on substrates is large, the binding strength is low, the thickness is not easily controlled,
environmental protection is not achieved, the operation space is large, and the repairing efficiency is low are solved; and the on-line laser reinforcing device has the characteristics of being simple in structure, small in
heat effect on substrate, high in binding strength, controllable in thickness,
environmentally friendly, capable of being suitable for small space operation, high in repairing efficiency, and easy and convenient to operate.
