Grinding device used for metal pipeline inner wall

Abstract

The invention discloses a grinding device used for a metal pipeline inner wall. The grinding device comprises a base, a first fixed frame is arranged on one side of the upper end of the base, a secondfixed frame is arranged on the other side of the upper end of the base, a third fixed frame is arranged at the position, between the first fixed frame and the second fixed frame, of the upper end ofthe base, fixing devices are arranged on the two sides of the upper end of the third fixed frame, a placing hole is formed in the upper end of the fixed frame, the placing hole penetrates the third fixing frame and the fixing devices in sequence, a first sliding groove is formed in the upper end of the first fixing frame, a sliding rod matched with the first sliding groove is arranged in the firstsliding groove, a grinding device body is arranged at one end of the sliding rod, the lower end of the first fixed frame is provided with a first rotating shaft in a penetrating and inserting manner,a movable rod is arranged on the first rotating shaft, the end, away from the first rotating shaft, of the movable rod is movably connected with one end of the connecting rod, the other end of the connecting rod is movably connected with one side of the sliding rod, a limiting groove is formed in the movable rod, and a first sliding block matched with the limiting groove is formed in the limitinggroove.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a grinding device for the inner wall of a metal pipeline. Background technique [0002] At present, pipelines are devices connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with solid particles. Due to their unique characteristics, pipelines are widely used in many industries and fields. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. As a type of pipe, metal pipes have strict requirements on the smoothness and no defects of the inner surface. Therefore, in most cases, the inner surface of the finished metal pipe needs to be polished to ensure the smoothness of the inner surface of the finished pipe, reduce or eliminate Defects, but the existing grinding device has a complex structure.

Problems solved by technology

As a type of pipe, metal pipes have strict requirements on the smoothness and no defects of the inner surface. Therefore, in most cases, the inner surface of the finished metal pipe needs to be polished to ensure the smoothness of the inner surface of the finished pipe, reduce or eliminate Defects, but the existing grinding device has a complex structure, because the size of the metal pipes is different, the grinding block needs to be replaced frequently, and the pipe is not easy to fix during the grinding process, which affects its grinding accuracy
