Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a refrigeration conveying pipeline processing fixture. Background Art

[0002] Pipe grinding is of great significance in the field of refrigeration, mainly in the following aspects:

[0003] First of all, grinding can ensure the welding quality of the delivery pipeline in the refrigeration equipment. Pipe welding is an indispensable link in the manufacturing and installation of refrigeration equipment. Through grinding, defects generated during the welding process, such as loose welds, pores, slag inclusions, etc., can be removed, thereby improving the welding quality and ensuring the sealing and integrity of the pipeline system.

[0004] Secondly, polishing can improve the surface quality of the pipe. The pipe system of refrigeration equipment usually requires high cleanliness and smoothness to reduce the resistance and friction of the fluid in the pipe and improve the refrigeration efficiency. Through polishing, the defects such as scale, stains, scratches on the pipe surface can be removed, making the pipe surface smoother and flatter, which is conducive to the smooth flow of refrigerant.

[0005] In the related art, the pipe is generally fixed with a bracket first, and then polished with a polishing device. However, the brackets in the related art generally adopt an upper and lower clamping support method. During polishing, they are easily affected by the polishing equipment and cause lateral deviation, resulting in repeated polishing of some areas, or incomplete polishing of some areas, which reduces the polishing efficiency.
