Description

Technical Field

[0001] The utility model relates to the technical field of surface weld grinding devices, and more specifically, to a steel pipe surface weld grinding device. Background Art

[0002] In the field of steel pipe manufacturing, steel pipe splicing is often carried out. The splicing of steel pipes is to weld the steel pipes, so welds will be formed on the surface of the steel pipes. The quality of the welds has an important influence on the overall performance and service life of the steel pipes. However, there are often defects such as bulges and burrs on the weld surface, which may affect the connection strength, sealing and appearance quality of the steel pipe. Therefore, it is necessary to grind the welds on the surface of the steel pipe. The existing steel pipe surface weld grinding device is usually composed of a grinding mechanism, a grinding table and a fixed rotating mechanism. When in use, the steel pipe is placed on the outer surface of the grinding table, and then one end of the steel pipe to be grinded is fixed by the fixed rotating mechanism, and then the grinding mechanism is used for grinding. Most of the fixed rotating mechanisms of this type of grinding device directly clamp the outer surface of the steel pipe, but due to the different thicknesses of the steel pipes, the clamping forces borne by the steel pipes are different, which may cause the clamped end of the steel pipe to deform, affecting its use quality and appearance, and greatly reducing the practicality of the grinding device. In order to solve the shortcomings of the prior art, we propose a steel pipe surface weld grinding device. Utility Model Content
