Pipe fitting self-adaption inner wall polishing device based on mechanical machining

Abstract

The invention discloses a pipe fitting self-adaption inner wall polishing device based on mechanical machining and relates to the technical field of mechanical machining. The pipe fitting self-adaption inner wall polishing device solves the problems that the machining length of a polishing device used at present is limited, machined parts are fixed, and the device does not have a function of increasing the length according to the use requirement. The pipe fitting self-adaption inner wall polishing device based on mechanical machining comprises a base. A sliding base is fixedly arranged in themiddle of the top of the front side of the base. Four sliding bars are integrally arranged on the two sides of the sliding base. A locking frame is arranged outside each sliding bar in a sliding manner. Meanwhile, a blocking frame is fixedly arranged on the edge side of each sliding bar. By arranging a polishing pipe shaft, the device can extend into a pipe fitting to polish the inner wall of thepipe fitting. An auxiliary pipe shaft is arranged at the rear end of the polishing pipe shaft, and can assist in improving balance of the polishing device. A connecting pipe shaft is arranged on the rear side of the auxiliary pipe shaft, and can increase the length through splicing, by means of the splicing manner, the polishing depth of the polishing device can be increased, and convenience is provided for the polishing device.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a mechanical processing-based self-adaptive inner wall polishing device for pipe fittings. Background technique [0002] A pipeline is a device used to transport gas, liquid or fluid with solid particles connected by pipes, pipe connectors and valves. Usually, after the fluid is pressurized by blowers, compressors, pumps and boilers, it flows from the high-pressure part of the pipeline to the low-pressure part, and it can also be transported by the pressure or gravity of the fluid itself. 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 installations; the inner wall of the pipeline is generally unchanged and polished with tools. [0003] After searching, for example, the patent No. CN110355628A discloses a pipel...

Problems solved by technology

[0007] The purpose of the present invention is to provide a mechanically-based self-adaptive inner wall polishing device for pipe fittings, to solve the problem that the currently used polishing device proposed in the above background technology has limited processing length, fixed processing parts, and does not have the ability to lengthen the working length according to the needs of use. At the same time, the polishing device does not have a cleaning structure, and the inner wall of the pipe cannot be purged and cleaned before the inner wall of the pipe is polished.
