[0015] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0016] This embodiment provides an automated repair device for high-speed train wheels, characterized by comprising an additive repair equipment housing 3. A horizontal bar 15 is positioned above the interior of the housing 3, connected to a vertical bar 15. The vertical bar 15 is connected to a laser 4. A laser cladding head 5 is positioned below the laser 4, and a wheel clamp 10 is positioned below the laser cladding head 5. A robotic arm 9 and a 3D scanning device 2 are positioned beside the wheel clamp 10, their positions corresponding to the wheel clamp 10. A grinding device 8 is connected to the robotic arm 9. A powder feeder 11 and a computing and control device 1 are positioned outside the additive repair equipment housing 3. The powder feeder 11 is connected to the laser cladding head 5 via a pipe. The computing and control device 1 is connected to the laser 4, robotic arm 9, powder feeder 11, 3D scanning device 2, and grinding device 8 for functional control. The vertical bar 15 is a telescopic structure, driven by a motor to move left and right on the horizontal bar 14, meaning the laser 4 can move in the up, down, left, and right directions.

[0017] The 3D scanning device 2 includes a 3D scanner, a camera, and an illumination source. The 3D scanning device 2 performs a 3D scan of the high-speed train wheel 7 to be repaired, automatically detects and identifies defects on the wheel 7, and provides various repair schemes using available metal powders and their properties. Simultaneously, it calculates the optimal repair path and presents it on the computing and control equipment. The 3D scanner scans the surface of the high-speed train wheel 7, detects defects, automatically determines the damage type, detects the material composition of the wheel 7, and acquires cloud data of metal powders with similar composition to the damaged area. After big data retrieval, it provides various repair schemes using available metal powders and provides the corresponding powder properties. It also obtains the 3D XYZ absolute coordinates of each point on the surface of the metal component to be repaired, constructs a solid model of the metal component based on the 3D XYZ absolute coordinates, and provides the optimal repair path. The camera performs optical imaging of the high-speed train wheel 7 through its optical lens, and the illumination source provides the necessary illumination for the camera's optical imaging.

[0018] The additive repair equipment housing 3 is also equipped with a temperature alarm device 6, which is used to monitor the temperature inside the additive repair equipment housing 3 in real time and issue an alarm when the temperature is too high. The computing and control device 1 is connected to the temperature alarm device 6. If an alarm occurs during operation, the computing and control device 1 obtains the alarm status and controls the laser 4, robotic arm 9, powder feeder 11, 3D scanning device 2 and grinding device 8 to stop working.

[0019] The additive repair equipment housing 3 is filled with argon gas of 99.99% purity to prevent oxidation of the wheels and repair materials during the repair process.

[0020] The grinding device 8 includes a grinding machine and a grinding stone. The grinding machine drives the grinding stone to rotate, thereby grinding the high-speed train wheels in a conformal manner.

[0021] The powder feeder 11 is equipped with a speed control button 13 for changing the powder feeding speed. The powder feeder 11 is located outside the additive repair equipment housing 3, which is convenient for operators to fill the powder at any time.

[0022] Working principle:

[0023] The surface coating and oil stains of the high-speed train wheel 7 to be repaired are manually cleaned to remove the surface oxide layer. The wheel is then placed on the wheel clamp 10. An image of the high-speed train wheel 7 to be repaired is scanned using a 3D scanning device 2, and the image data is transmitted to a computing and control device 1. The computing and control device 1 processes the image data to obtain the 3D X, Y, and Z absolute coordinates of each point on the surface of the metal parts of the high-speed train wheel 7 to be repaired. Based on these 3D X, Y, and Z absolute coordinates, a solid model of the metal parts of the high-speed train wheel 7 to be repaired is constructed. Simultaneously, combined with the composition of the high-speed train wheel 7 detected after scanning, the computing and control device 1 compares the various repair powders available from the powder feeder 11 and their properties, selects the optimal powder, and applies it to the surface of the high-speed train wheel 7 to be repaired. The solid model of the metal parts of the high-speed train wheel 7 is compared with the solid model of the metal parts of the undamaged high-speed train wheel to obtain the model of the missing part that needs to be repaired. Then, the additive filling path required for laser additive repair is generated. According to the planned additive filling path, the missing part of the metal parts of the high-speed train wheel 7 to be repaired is laser 3D printed for additive filling repair. After the laser additive repair is completed, the grinding device 8 is moved to the repaired high-speed train wheel 7 by the robotic arm 9 and ground to make the shape and size of the original defect meet the requirements of the drawing. The quality and assembly inspection of the repaired high-speed train wheel 7 is carried out. When its shape, size and surface quality are qualified, the repair process ends.

[0024] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
