Movable laser cladding and repairing system

Abstract

The invention provides a movable laser cladding and repairing system in the field of laser cladding and repairing. The movable laser cladding and repairing system comprises a movable platform, wherein a laser, a robot, a position changing machine, a powder feeder, an image processing system, a control system (comprises a PLC (programmable logic controller) main control system, a PC (personal computer) computing workstation), a video camera, a three-dimensional laser scanning sensor, a laser processing head and a coaxial powder feeding head are fixedly arranged on the movable platform. The movable laser cladding and repairing system takes the robot as a moving body, controls the clad pool size, the temperature and other information by using an image acquiring and processing system, and scans a workpiece to slice, stratify and automatically clad a three-dimensional workpiece model based on the three-dimensional laser sensor; the movable laser cladding and repairing system is convenient and flexible, simplifies a repairing process, achieves precision and self-adaptive control of a cladding process, effectively improves the cladding quality, and facilitates field application of a large component through the movable platform.

Description

technical field [0001] The invention belongs to the technical field of surface cladding and repairing of high value-added, precise or large parts, and particularly relates to a computer-controlled movable laser cladding and repairing system. Background technique [0002] The methods of repairing parts mainly include laser cladding, vacuum brazing, vacuum coating welding, tungsten inert gas shielded welding and plasma cladding repair. Laser cladding is to clad metals or non-metals of various design components according to the working conditions of the workpiece, prepare heat-resistant, corrosion-resistant, wear-resistant, anti-oxidative, anti-fatigue or surface cladding with optical, electrical and magnetic properties Floor. Laser cladding is a rapid cooling process, with less heat input to the substrate, small heat-affected zone, fine cladding layer structure, and easy automation. Therefore, laser cladding is used to repair parts such as rotors. Other methods have greater ...
