Abstract

The invention discloses a device for repairing gears by means of laser cladding, belonging to the field of laser processing. The device comprises a three-dimensional mobile platform, a programmable logic controller (PLC) system, a laser metal deposition system, a fixture and a motor. When the device is in use, the gear to be repaired is fixed on the fixture, and the broken teeth of the gear are enabled to be placed on a horizontal plane by controlling the motor. The device has the advantages of being simple in structure and convenient to operate, improving gear repairing quality and efficiency, having higher flexibility, and being capable of clamping the gears with different inner hole sizes.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to a device for repairing gears by laser cladding. Background technique [0002] Gears are an important part of mechanical systems that carry motion loads. During the use of gears, they fail due to tooth surface wear, pitting and peeling of tooth surfaces, cracks and broken teeth. The normal work of the mechanical system will be seriously affected due to the failure of the gears, resulting in accidents. The scrapping of gears will cause a waste of resources due to its high manufacturing cost. [0003] The repair and remanufacturing of gears is a difficult point that plagues equipment technical maintenance workers. Many domestic practitioners in the mechanical field have carried out various remanufacturing technologies, such as surfacing, spraying and electroless plating, but the results have not achieved the expected results. [0004] As an emerging surface modification technology,...
