Device and method of rotating slotting magnetic pole polishing of inner surface of pipe fitting

Abstract

The invention relates to a device and method of rotating slotting magnetic pole polishing of the inner surface of a pipe fitting. The device comprises a horizontal driving mechanism, a vertical driving mechanism, a rotating motor, a rotating motor supporting plate, a slotting magnetic pole, a magnetic pole chuck, a main motor, a triangular chuck and a base. The horizontal driving mechanism is connected with the vertical driving mechanism and drives the vertical driving mechanism to move in the horizontal direction, and the vertical driving mechanism is connected with the rotating motor through the rotating motor supporting plate. The rotating motor drives the magnetic pole chuck to rotate, and the slotting magnetic pole is clamped on the magnetic pole chuck. The base is fixed to the horizontal driving mechanism, and the main motor drives the triangular chuck. One end of a workpiece is clamped on the triangular chuck, and the other end of the workpiece is limited by a tail base. The workpiece is arranged below the slotting magnetic pole. The device and method have the advantages that the inner surface of the pipe fitting can be processed, the rotating magnetic pole drives magnetic abrasive particles, the movement trail is more complex, the impact scratch caused by the magnetic abrasive particles on the pipe fitting which needs to be processed is more complex, and therefore the surface roughness of the pipe fitting which needs to be processed can be improved.

Description

technical field [0001] The invention belongs to the technical field of magnetic grinding and surface finishing, and in particular relates to a device and method for polishing the inner surface of a pipe fitting with rotating slotted magnetic poles. Background technique [0002] In traditional mechanical processing, pipe fittings are more and more widely used in high-tech fields such as aviation, automobiles, and food machinery, and various new types of parts have emerged as the times require. The technical requirements for pipe fittings are getting higher and higher, not only to ensure the dimensional accuracy of the inner surface of the pipe fittings, but also to ensure that the parts have a better microscopic appearance. When the inner surface of the pipe fitting is uneven, the phenomenon of uneven flow rate or surge often occurs, which will have a certain impact on precision instruments, so it is of great significance to ultra-precision grinding of the inner surface of th...

AI Technical Summary

Problems solved by technology

[0005] At present, most of the grinding devices for the inner surface of pipe fittings use a single rotation method to grind the inner surface. The movement trajectory of the magnetic abrasive particles on the inner surface is relatively single, which cannot continue to improve the surface quality.
