Description

Technical Field

[0001] This utility model relates to the field of grinding devices, and in particular to a grinding device that is convenient for grinding the surface of steel structures. Background Technology

[0002] Surface grinding of steel structures is an important part of steel structure processing and construction. Its main purpose is to remove rust, oxide layer and dirt from the surface of the steel structure to make it clean and smooth, so as to carry out subsequent painting or other treatments.

[0003] The utility model patent with publication number CN 218081810 U in the prior art proposes a grinding device for steel structure surfaces, which solves the problem that it can only grind plate-shaped steel structure components and cannot grind the surface of tubular steel structure components. This helps to improve the practicality of the device and reduce the processing cost of steel structures.

[0004] However, it lacks the ability to adjust the device and can only clamp and limit tubular steel structures with a certain inner diameter. When facing tubular steel structures with large variations in inner diameter, it cannot effectively maintain the stability of the steel structure and is prone to sliding and displacement problems, which affect the processing quality of the device. At the same time, it does not have the ability to collect dust, and the dust generated during the processing will fly around, affecting the processing quality of the workpiece. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content
