Self guiding bent pipe inner surface magnetic abrasive finishing device and method

Abstract

The invention relates to a self guiding bent pipe inner surface magnetic abrasive finishing device and method. The device comprises a rotating driving mechanism, a maintaining machine frame, a rotating machine frame, a magnetic pole clamping mechanism and a guiding walking mechanism. The maintaining machine frame and the rotating machine frame are both annular components, and arranged at the periphery of the bent pipe in a sleeving mode. The rotating machine frame is rotatably connected with the maintaining machine frame, and the rotating machine frame can rotate circumferentially around the bent pipe under driving of the rotating driving mechanism. The guiding walking mechanism is arranged on the maintaining machine frame, under driving of the guiding walking mechanism, the magnetic abrasive finishing device can integrally move in the axis direction of the bent pipe. The magnetic pole clamping mechanism is arranged on the rotating machine frame, and a magnetic pole in the magnetic pole clamping mechanism is matched with a magnetic abrasive material filled in the bent pipe to achieve magnetic abrasive finishing of the inner surface of the bent pipe. The self guiding bent pipe innersurface magnetic abrasive finishing device can adapt to the inner surface finishing of the bend pipes in different irregular shapes, the device is simple in structure, convenient to operate, high inmachining efficiency and low in machining cost.

Description

technical field [0001] The invention relates to the technical field of magnetic grinding, in particular to a magnetic grinding device and method suitable for the inner surface of a self-guiding elbow with an irregular curved shape. Background technique [0002] With the development of high-tech fields such as aerospace, in order to adapt to the complex and narrow space inside the equipment and meet the needs of use, irregular-shaped elbows with small duty ratios are often used; however, due to the very complicated shape of the elbows, it is difficult for traditional processing techniques to ensure that the parts The internal surface quality of the elbow often produces wrinkles, pits and micro-cracks on the inner surface of the bend, and the surface of the inner cavity of the elbow is rough and uneven, resulting in turbulence, vibration and corrosion when liquid or gas flows through. The mechanical performance of the bent pipe is reduced, resulting in unstable working perform...
