Description

Technical Field

[0001] The utility model relates to the technical field of shaft repair, and more specifically to a reference surface scraping and grinding shaft repair device. Background Art

[0002] Shafts are usually in the shape of metal round rods. Their main purpose is to support rotating parts, such as gears, pulleys, bearings, couplings, etc., and rotate with them to transmit motion, torque or bending moment. As the working time of the shaft increases, its reference surface is prone to wear and needs to be repaired by scraping to facilitate subsequent use.

[0003] Based on the above, the inventors found that the existing repair device mainly fixes the shaft by a clamp, and then performs scraping and grinding operations manually. However, before scraping and grinding, it is necessary to apply a colorimetric reagent to determine the scraping part, but manual application is inefficient and prone to omissions. Therefore, in view of this, the existing structure is studied and improved, and a reference surface scraping and grinding shaft repair device is provided, in order to achieve a more practical purpose.
