Description

Technical Field

[0001] This utility model relates to the field of welding technology for mine car wheel rims, specifically a two-axis U-shaped displacement device. Background Technology

[0002] A mine car wheel rim is a ring-shaped component installed on the outermost edge of a mine car wheel. It surrounds the wheel's core, acting like a sturdy "outer coat" for the wheel. Its main function is to provide a mounting base for tires or other running gear. In mine cars with rubber tires, the tires are directly mounted on the rim. For mine cars that use steel rims to run on rails, the rim is tightly connected to the rail contact area. It is usually a high-strength and tough metal structure, generally circular in shape with a specific cross-sectional shape, such as the common "U" or "L" shape. This shape design helps increase the strength of the rim, enabling it to withstand the enormous pressure generated when the mine car is fully loaded with heavy loads such as ore. Moreover, the edges of the rim are usually specially treated, such as rounded corners or reinforced edge thickness, to prevent damage from collisions or other accidents during operation.

[0003] Chinese Invention Patent Publication No. CN117484056A discloses a welding and fixing device for processing wheel rims. This device automatically fixes the spokes to the rim through the coordinated use of a rim fixing mechanism, a spoke fixing mechanism, and a welding mechanism. Although this welding and fixing device can automatically clamp and rotate, it cannot perform flip welding of mining wheel rims. It can only weld one side of the mining wheel rim and cannot weld the other side. Its practicality is poor, it cannot improve welding efficiency, and the device is also large and overly complex, failing to reduce the operating costs for enterprises. Summary of the Invention
