Description

Technical Field

[0001] The utility model relates to the technical field of pipe opening grinding, and more specifically to a device for grinding and smoothing the surface of positive and negative grooves of pipelines after welding. Background Art

[0002] Yin-Yang grooves refer to the inclined surfaces cut into different angles on the inner and outer sides of the pipe end, which are used to connect two pipes. After the pipes are welded and fixed, the welding position of the pipes needs to be polished by a polishing and smoothing device to make the welding position smooth and flat, which is convenient for the subsequent use of the pipes.

[0003] Based on the above, the inventors found that the existing grinding and smoothing device needs to grind the inner and outer sides of the pipeline welding position in batches to ensure the smoothness of the inner and outer sides of the yin-yang groove, but the grinding device is inconvenient to adjust and the grinding efficiency is low. Therefore, in view of this, the existing structure is studied and improved to provide a surface grinding and smoothing device for the yin-yang groove of the pipeline after welding, in order to achieve a more practical purpose.

The grinding wheel is supported and limited by a stabilizing component, thereby improving the grinding stability and grinding effect of the grinding wheel.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:
