Metal pipe fitting polishing device

Abstract

The invention discloses a metal pipe fitting polishing device, and belongs to the technical field of pipe fitting polishing, the metal pipe fitting polishing device comprises a supporting unit, fixing units mounted at the two ends of the supporting unit and a plurality of driving assemblies circumferentially and uniformly arranged on the outer side of the supporting unit, and at least one end of the fixing units arranged at the two ends of the supporting unit is provided with a polishing piece; the supporting unit comprises a shaft sleeve, telescopic pieces arranged in the axial direction are installed at the two ends of the shaft sleeve correspondingly, and the two fixing units are installed at the telescopic ends of the two telescopic pieces correspondingly. The driving assembly of the device can be tightly attached to the inner wall of the pipe fitting to drive the device to move forwards; the front end and the rear end of the device do not incline and approach to one side, so that the polishing is more uniform.

Description

technical field [0001] The invention belongs to the technical field of grinding devices, and in particular relates to a grinding device for metal pipe fittings. Background technique [0002] After the metal pipe fittings are produced, they will be put into production and processing after being transported and stored by multiple parties. After a long period of storage, both the inner wall and the outer wall will be oxidized. The outer wall of the pipe fittings is polished by a conventional grinding device to achieve a smooth surface. , When rust occurs on the inner wall, it is difficult to clean. When the length of the pipe fitting is short, the inner wall is relatively easy to clean. When the length of the pipe fitting is long, it is difficult for ordinary grinding devices to complete the grinding work. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a grinding device for metal pipe fittings, which ...
