A laser cladding device applied to workpiece repair

Abstract

The invention relates to a laser cladding device applied to workpiece repair, comprising a cladding platform, a clamping device, cladding processing equipment and cladding processing equipment, the cladding platform is provided with a clamping device, and the cladding processing equipment includes a traveling mechanism , a heating device and a powder recovery device, the traveling mechanism includes a first guide rail, a walking frame, and a moving frame, the number of the first guiding rails is two and distributed on both sides of the clamping mechanism, and the bottoms of both ends of the walking frame are slidingly set On the two second guide rails, the mobile frame is located above the walking frame, the top of the mobile frame is provided with a scissor lifting frame, the top of the scissor lifting frame is provided with an installation platform, and a heating device and a powder recovery device are arranged on the installation platform. The heating device is driven by the walking mechanism to move in three dimensions, the heating seat is set outside the position of the workpiece to be clad, and the infrared heating tube is used to preheat the workpiece locally, which effectively guarantees the cladding quality.

Description

technical field [0001] The invention belongs to the technical field of cladding devices, and in particular relates to a laser cladding device applied to workpiece repair. Background technique [0002] Laser cladding, also known as laser cladding or laser cladding, is a new surface modification technology. It forms a metallurgically combined additive cladding layer on the surface of the base layer by adding a cladding material on the surface of the base material, and using a high-energy density laser beam to fuse it with a thin layer on the surface of the base material. According to its application characteristics, parts with certain deep manufacturing defects, misprocessing damage or service damage can be repaired. [0003] (1) At present, the laser cladding equipment can realize the cladding of flat plates, shaft parts, and simple rotary cylindrical parts. However, for some special-shaped workpieces with complex structures, such as workpieces with various bracket structure...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the above problems, the present invention discloses a laser cladding device applied to workpiece repair, which solves the problem that the clamping equipment has a single fixed structure and cannot satisfy the positioning cladding of special-shaped workpieces, and at the same time adopts a high-efficiency water cooling structure to effectively carry out laser cladding. The cooling ensures the normal operation of the laser; the heating device is used to preheat the workpiece, which solves the phenomenon of cracks in the cladding layer of the workpiece, and finally the powder recovery device is used to recover the powder that falls during the cladding process and the floating powder recycle and re-use
