Abstract

The invention relates to a magnetic particle grinding device and method for efficient polishing of the inner surface of a pipe. The device comprises a driving mechanism, a feeding mechanism and a magnetic field generating mechanism. The driving mechanism drives a pipe part to rotate, and the feeding mechanism drives the magnetic field generating mechanism to axially move along the pipe part. The magnetic field generating mechanism forms a magnetic field to adsorb magnetic grinding particles to be distributed along the magnetic force line and gathered into a magnetic grain brush with rigidity.A connecting frame is fixedly connected with a large belt wheel through fastening screws, the connecting frame is composed of two semicircular structures, gears are fixed at the two ends of the semicircular structures, the two semicircular structures are meshed with each other, an adjusting knob is fixedly connected with the gear of one semicircular ring structure, a magnetic pole frame is fixed at one end and the middle vertex of the semicircular annular structure, and a magnetic pole is arranged on the magnetic pole frame. The device and method have the advantage that pipe parts with scratches, pits, creases, micro cracks and other defects on the surfaces can be efficiently ground and polished.

Description

technical field [0001] The invention belongs to the technical field of precision machining and special machining, and in particular relates to a magnetic particle grinding device and method for efficiently polishing the inner surface of a tube. Background technique [0002] As the country vigorously develops high-precision manufacturing industries such as electronic products, precision instruments, and aerospace, the demand for pipe products has increased significantly, and the surface morphology of pipe parts directly affects the quality of the final product. Limited by the processing technology, most of the pipe parts have scratches, pits, wrinkles, micro-cracks and other defects on the surface, which affect their service life and easily cause hidden dangers. For example: the hydraulic conduit in the hydraulic piping system of an aero-engine, because the cold bending process will cause defects on the inner surface of the hydraulic conduit, the uneven pressure load distribu...
