Polishing device for inner wall surface of metal pipe joint

Abstract

The invention is suitable for the technical field of metal polishing, and provides a polishing device for the inner wall surface of a metal pipe joint. The polishing device comprises a plurality of polishing parts and further comprises an adjustable rotating frame mechanism, a rotary follow-up moving mechanism and an angle adjusting mechanism, and the adjustable rotating frame mechanism comprises a polishing adjusting assembly, a rotating connecting assembly and a mounting frame; the rotary follow-up moving mechanism is mounted on the mounting frame; and the angle adjusting mechanism comprises an adjusting seat, a mounting seat, an adjusting connecting assembly and an adjusting transmission assembly. According to the polishing device for the inner wall surface of the metal pipe joint, the adjusting type rotating frame mechanism, the rotating follow-up moving mechanism and the angle adjusting mechanism are arranged, and the relative distance between the multiple polishing parts can be adjusted, so that the multiple polishing parts can polish the inner walls of the metal pipe joints of different sizes, universality is high, different polishing devices do not need to be arranged for metal pipes of different sizes, and the machining cost can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of metal polishing, and in particular relates to a polishing device for the inner wall surface of a metal pipe joint. Background technique [0002] Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It is a modification process on the surface of the workpiece by using polishing tools and abrasive particles or other polishing media. Polishing cannot improve the dimensional accuracy or geometric shape accuracy of the workpiece, but for the purpose of obtaining a smooth surface or mirror luster, and sometimes it is also used to eliminate gloss. [0003] For the processing of metal pipe joints, it is necessary to use a polishing device for the inner wall of metal pipe joints to polish the inner wall of metal pipe joints. The existing polishing devices for the inner wall of metal pipe joints usuall...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the embodiments of the present invention is to provide a polishing device for the inner wall of metal pipe joints, which aims to solve the following problems: the existing polishing devices for the inner wall of metal pipe joints are usually simple in structure and cannot be adjusted, resulting in the inability to process different sizes of metal pipe joints. The inner wall of the pipe joint is polished, and the versatility is not high
