The invention relates to the technical field of pipe inner surface polishing, in particular to a non-magnetic-conductive concentric reducing pipe inner surface magnetic particle grinding device and method. A gear rotation mechanism, a sliding reducing mechanism, a lathe, a magnet, a distance measuring sensor and a PLC control system are included. The lathe is sequentially provided with a main shaft box, a sliding box I and a sliding box II. The two ends of a workpiece are clamped to a triangular chuck I connected with the main shaft box and a triangular chuck II connected with the sliding boxII correspondingly, and the gear rotation mechanism is arranged on the sliding box I. The sliding reducing mechanism is arranged on the inner end face of a large gear, the sliding reducing mechanism is of a telescopic structure, the magnet is arranged at the end portion of the sliding reducing mechanism, and the large gear drives the magnet to rotate to form a rotation magnetic field. The distancemeasuring sensor is arranged on the magnet, and the PLC control system is electrically connected with the distance measuring sensor and the sliding reducing mechanism. The non-magnetic-conductive concentric reducing pipe inner surface magnetic particle grinding device and method are high in machining efficiency, good in precision and capable of being widely applied to non-magnetic-conductive concentric reducing pipe inner surface magnetic particle grinding and polishing.
Description
Technical field [0001] The invention relates to the technical field of tube inner surface polishing, in particular to a magnetic particle grinding device and method for the inner surface of a non-magnetic concentric diameter reducing tube. Background technique [0002] With the rapid development of petroleum, chemical, natural gas and other industries, various new types of pipe fittings have emerged. The processing requirements for parts are getting higher and higher, not only to ensure the dimensional accuracy of the parts, but also to have a good microscopic surface morphology, corrosion resistance and fatigue resistance. The purpose of the non-magnetic concentric reducing pipe is to connect pipelines or valves with different diameters in the transportation of oil and gas pipelines. At present, the processing methods targeted at non-magnetic concentric reducer pipe manual polishing and chemical polishing, but manual polishing not only has high labor costs, but also has high la...
