Description

Technical Field

[0001] The invention belongs to the fields of additive manufacturing, robotics and industrial automation, and laser cladding technology, and in particular relates to a mobile shelter equipment specially used for on-site laser cladding repair of shaft and bearing parts. Background Art

[0002] As key transmission and support parts in mechanical equipment, the performance of shafts and bearings is directly related to the stability and reliability of the entire system. However, in the long-term operation process, these parts are often damaged due to wear, fatigue, corrosion and other reasons, resulting in performance degradation or even failure, thus affecting the operation efficiency and safety of the entire equipment. Traditional methods for repairing shafts and bearings mainly include machining, electroplating, thermal spraying and other technologies. Although these methods can restore the size and shape of parts to a certain extent, they have many limitations. For example, machining may remove too much material, resulting in a decrease in part strength; electroplating and thermal spraying technologies may fail quickly under high loads or harsh environments due to insufficient bonding between the coating and the substrate.

[0003] In order to overcome the shortcomings of the above-mentioned traditional repair technologies, laser cladding technology, as an advanced surface modification technology, has been widely used in the repair of shaft and bearing parts in recent years. Laser cladding technology melts special repair materials and covers the surface of the base material by precisely controlling the high-energy laser beam to form a coating with specific properties, which can significantly improve the wear resistance, corrosion resistance and fatigue life of the parts. Laser cladding technology has the advantages of high energy, rapid melting and precise control.

[0004] Although laser cladding technology has significant advantages in theory, in practical applications, since the equipment is not convenient to move and has high requirements for the working environment, laser cladding is usually set up in special factories or rooms, which limits its application in industrial sites.
