Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting elbow processing, in particular to a grinding device for processing electric power pipe fitting elbows. Background Art

[0002] In the infrastructure construction of electric power projects, pipe fitting elbows, as key connecting components, their quality and processing accuracy directly affect the safe operation and efficiency of the entire power transmission system. Among them, the flatness and smoothness of the elbow end face are important factors determining the welding quality and sealing performance. However, in the traditional processing of electric power pipe fitting elbows, especially in the grinding process of burrs on the elbow end face, there are generally many drawbacks caused by the inability of the grinding device to adapt to different bending angles. This not only hinders the improvement of processing efficiency but also seriously affects the quality of the final product and the safety and reliability of the system.

[0003] In the current field of electric power pipe fitting elbow processing, most of the grinding devices for trimming burrs on the end face adopt a fixed design, that is, the movement trajectory and angle of the grinding head are not adjustable. This limitation in design makes it difficult for the grinding device to accurately fit the curve contour of the elbow when facing pipe fitting elbows with different bending angles, resulting in the following main problems:

[0004] Uneven grinding: The fixed grinding trajectory is difficult to perfectly fit the elbow curved surface, resulting in uneven grinding force. Some areas may be over-ground and appear sunken, while in some areas, the burrs are not effectively removed, affecting the flatness and aesthetics of the end face.

[0005] Low efficiency: For elbows with different angles, it is necessary to frequently change tools or manually adjust the grinding posture. This process is time-consuming and laborious, greatly reducing the processing efficiency and increasing the labor cost.

[0006] Quality problems: Improper grinding not only affects the appearance, but more importantly, it may damage the structural integrity of the pipe fitting, leaving tiny cracks or stress concentration points, becoming potential failure sources during future operation. In severe cases, it may lead to leakage or fracture accidents.

[0007] Therefore, how to provide a grinding device for processing electric power pipe fitting elbows is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model
