Abstract

The invention relates to a laser cladding device applied to workpiece repair. The device comprises a cladding platform, clamping equipment, cladding processing equipment and cladding treatment equipment, wherein the clamping equipment is arranged on the cladding platform, the cladding treatment equipment comprises a travelling mechanism, a heating device and a powder recovery device, the travelling mechanism comprises first guide rails, a travelling frame and a moving frame, the two first guide rails are distributed on the two sides of clamping mechanisms correspondingly, the bottoms of the two ends of the travelling frame are arranged on two second guide rails in a sliding mode, the moving frame is located above the travelling frame, a shear type lifting frame is arranged at the top of the moving frame, a mounting platform is arranged at the top end of the shear type lifting frame, and the heating device and the powder recovery device are arranged on the mounting platform. According to the laser cladding device, the heating device is driven by the travelling mechanism to move in the three-dimensional direction, a heating base is arranged on the outer side of a to-be-cladded position of a workpiece, the workpiece is locally preheated by means of an infrared heating pipe, and the cladding quality is effectively guaranteed.

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 bonded cladding layer on the surface of the base by adding cladding materials on the surface of the substrate and using a high-energy-density laser beam to fuse it together with the thin layer on the surface of the substrate. According to its application characteristics, parts with certain deep manufacturing defects, misprocessing damage or service damage can be repaired. [0003] (1) At present, laser cladding equipment can realize flat plate cladding, shaft cladding, and simple rotary outer circular parts cladding, but for some special-shaped workpieces with complex structures, such as workpieces with various bracket structures, the It is rela...

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
