Description

Technical Field

[0001] The utility model belongs to the technical field of pipe fitting processing, and in particular relates to a firmly fixed pipe fitting inner wall grinding device. Background Art

[0002] During the production and processing of steel pipes, the inner wall of the steel pipe needs to be polished and cleaned for subsequent processing of the steel pipe. For the cleaning of the inner wall of the steel pipe, the steel pipe fittings are generally clamped, and then the polishing head is inserted into the pipe fittings for polishing with continuous high-speed rotation.

[0003] In the prior art, when grinding pipe fittings, the pipe fittings are placed on rotating rollers, and the rotating rollers are used to drive the pipe fittings to rotate, so that the inner wall of the pipe fittings is ground by the grinder. However, there are still some problems in using this method. For example, the pipe fittings are placed on rotating rollers and lack a limiting mechanism. When grinding, the pipe fittings will shake when they contact the grinding wheel, which will affect the safety of the pipe fittings and the effect and efficiency of subsequent pipe grinding. In addition, the pipe fittings are prone to move when they rotate. The movement of the pipe fittings will not only affect the safety of the processing process, but also affect the grinding efficiency.
