Inner wall polishing device with self-adaptive adjusting structure for pipeline machining

Abstract

The invention relates to the technical field of pipeline inner wall polishing, in particular to an inner wall polishing device with a self-adaptive adjusting structure for pipeline machining. The inner wall polishing device comprises a driving assembly and a second motor, and the second motor is fixedly connected to the right side of the driving assembly. A fixing support is fixedly connected to the outside of the driving assembly and the second motor, an adjusting assembly is arranged on the right side of the fixing support, and a traction assembly is movably connected to the right side of the adjusting assembly. The traction assembly comprises first traction rods, rotating blocks are movably connected to the right sides of the first traction rods, and clamping blocks are movably connected to the right sides of the rotating blocks. The second motor is fixedly connected to the bottom of the traction assembly, and a fixing ring is arranged on the right side of the second motor. Through linkage arrangement of the adjusting assembly and the traction assembly, height adjustment of polishing assemblies can be achieved, and then self-adaptive adjustment of polishing pieces on the inner diameter of a pipeline is achieved.

Description

technical field [0001] The invention relates to the technical field of pipeline inner wall grinding, in particular to an inner wall grinding device with an adaptive adjustment structure for pipeline processing. Background technique [0002] The pipeline is a device connected by pipes, pipe connectors and valves to transport gas, liquid or fluid with solid particles. The pipeline has a wide range of uses, mainly used in water supply, drainage, heat supply, gas supply, long-distance In the transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations, the pipeline needs to be extended by welding, but when the pipeline is welded, the welding point is prone to burrs. When using and processing, it is necessary to use a grinding device to grind the inner wall to avoid burrs or welding residues inside the pipe, which will affect the later use of the pipe. [0003] In this regard, China's patent application No.: CN1036444...
