In the traditional train wheel maintenance process, multiple steps from rust removal, grinding to painting often require different equipment support, and the conversion of each step is accompanied by the handling and repositioning of the workpiece, which not only takes up a lot of space, but also increases the complexity and cost of the operation. Especially for large components such as train wheels, their large size and heavy weight make it particularly inconvenient to transfer between different workstations, which easily leads to a waste of time and resources, and affects the continuity and efficiency of the entire production line.

The space utilization rate is low, and the equipment installation and maintenance costs are high. In addition, although the traditional manual grinding method is flexible, it relies on the operator's skills and physical strength, has limited efficiency, and it is difficult to ensure the consistency and quality standards of each grinding.

[0032] In order to make the purpose, technical solution and advantages of the implementation mode of the present invention clearer, the technical solution in the implementation mode of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation mode of the present invention.

[0033] like Figure 1 , Figure 2 As shown, it is a first embodiment of an integrated railway wheel chain grinding device provided by the utility model. In this embodiment, it includes a frame 10, and slide rails are respectively arranged on the left and right sides of the frame 10. A first motor 20 is arranged at the front end of the frame 10, and the first motor 20 is axially connected to a transmission device 40. The transmission device 40 adopts a double-row roller chain. A fixed seat 50 is slidably installed on the track of the transmission device 40. A second motor 30 is arranged at the bottom of the fixed seat 50. The second motor 30 is transmission-connected to the first motor 20 through a gear transmission mechanism;

[0034] like Figure 3 , Figure 4 As shown, the fixing seat 50 is provided with a bottom bracket 51 , which is located at the bottom of the fixing seat 50 and is slidably connected to the frame 10 via a slide rail.

[0035] Among them, in the above technical scheme, the fixed seat 50 also includes a slewing bearing 52, a support frame 53, and a cylindrical positioning workpiece 54. The bottom support 51 is located on both sides of the bottom of the support frame 53, the slewing bearing 52 is located at the top of the support frame 53, and a plurality of cylindrical positioning workpieces 54 are arranged above the slewing bearing 52. A second motor 30 is arranged at the bottom of the slewing bearing 52.

[0036] Furthermore, in the above technical solution, the number of the cylindrical positioning workpieces 54 is four.

[0037] Furthermore, in the above technical solution, the bottom bracket 51 is located at the contact position between the fixing seat 50 and the frame 10 , and the length of the bottom bracket 51 is equal to the width of the frame 10 .

[0038] Furthermore, in the above technical solution, the support frame 53 is a square, and the side length of the square is equal to the width of the frame 10 .

[0039] Furthermore, in the above technical solution, the transmission device 40 specifically includes a driving sprocket, a driven sprocket, and a double-row roller chain. The driving sprocket is directly connected to the output shaft of the first motor 20, and the driven sprocket is installed at the front end of the base 51.

All components are closely matched through precise machining and assembly processes to ensure efficient and stable operation of the entire chain transmission device.

The driving gear is adjacent to the motor and connected to the driven gear. The axial and radial positions between the gears are corrected by precise bearing seats and adjustment shims to ensure accurate meshing of the gears during operation while reducing vibration and noise. All gear components are enclosed in a closed or semi-closed housing to contain lubricating oil and protect the gears from external contamination, while also helping to dissipate heat and ensure long-term stable operation of the system.

[0043] Furthermore, in the above technical solution, the second motor 30 is specifically a 200W reduction motor.

[0045] Furthermore, in the above technical solution, the frame 10 is rectangular, and the frame 10 is formed by welding rectangular steel pipes.

[0046] Specifically, the principle of the utility model is:

[0047] Modular integrated design: The modular design concept is adopted to scientifically integrate the chain conveying module and the rotary grinding module.
