Handheld type pipeline end opening inner wall polishing device

Abstract

The invention discloses a handheld type pipeline end opening inner wall polishing device comprising a shell, a rotating pipeline, a polishing head, a rotating connector, a motor and a storage battery.The upper portion of the left wall of the shell is provided with the rotating pipeline. The periphery of the rotating pipeline is provided with a polishing head, a brush, spray nozzles, sliding ringsleeves and a belt pulley. The right end of the rotating pipeline is connected with a miniature air pump through a rotating connector. Each sliding ring sleeve is composed of a ball bearing and sliding strips. The upper side and the right side of the sliding ring sleeve on the right side are provided with threaded adjusting rods. The upper end and the right end of the sliding ring sleeve on the left side are provided with sliding loop bars. The threaded adjusting rods and the sliding loop bars are provided with holding plates in a connected manner. The opposite inner sides of the holding plates are provided with rotating rods and tightly pressing plates. A motor and a storage battery are arranged in the shell. The right side of the shell is provided with a handle rod. By the adoption of the handheld type pipeline end opening inner wall polishing device, a pipeline can be stably clamped and fixed, the machining depth is freely adjusted, chippings generated by polishing during machiningcan be synchronously cleaned and rapidly blown away, the machining precision is improved, and it is guaranteed that the pipeline is clean.

Description

technical field [0001] The invention relates to a pipeline grinding device, in particular to a hand-held pipeline port inner wall grinding device. Background technique [0002] Pipe is the material used to make pipe fittings. Different pipe fittings use different pipe materials, and the quality of the pipe directly determines the quality of the pipe fittings. Such pipes are often used in construction projects, power plants, chemical plants, etc. There is an implementation standard GB / T5310, for high-pressure boilers: there is an implementation standard GB / T8163, seamless steel pipes for conveying fluids: there is an implementation standard GB3087, seamless steel pipes for low-pressure boilers : There is the implementation standard GB / T9948, seamless steel pipe for petroleum cracking: there is the implementation standard GB / T14976, stainless steel seamless steel pipe for fluid transportation, common materials are alloy (15CrMo, 12Cr1MoV) carbon steel (10#, 20#, 45# ) stainl...

AI Technical Summary

Problems solved by technology

[0003] After the pipe is cut and welded, the inner wall of the pipe generally needs to be polished. Large-scale mechanical grinding devices are not suitable for most small places. However, the existing hand-held grinding devices generally have the problem of unstable processing, and skilled processing skills are required. Only workers can operate, and the accumulation of debris on the inner wall of the pipe during processing will not only affect the grinding accuracy of the inner wall of the pipe in subsequent processing, but also cause problems that are difficult to clean
