Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings, but it should be pointed out that the implementation of the present invention is not limited to the following embodiments.

[0024] See figure 1 , figure 2 , double permanent magnetic pole alternating magnetic field magnetic grinding processing device, including support base 15, base 9, magnetic poles, motor with shield 2, shielding disc 3, transmission mechanism, cylindrical mold 5, magnetic abrasive grains, support base 15 installed on the base 9, the magnetic poles are installed on the support base 15, and the motor with shielding cover 2 is fixed above the magnetic poles, and is supported and fixed by the motor base 1. In order to prevent the permanent magnetic pole magnetic field generated by the magnetic poles from interfering with the motor, a magnetic shielding cover is installed outside the motor. Become band shield motor 2. There are two magnetic poles, na...

Abstract

The invention relates to a dual-permanent-magnet-pole alternating magnetic field magnetic grinding machining device. The dual-permanent-magnet-pole alternating magnetic field magnetic grinding machining device comprises a supporting base, a base, magnet poles, motors with shielding cases, shielding discs, a transmission mechanism, a cylindrical mold and magnetic abrasive particles; the supportingbase is arranged on the base, the magnet poles are arranged on the supporting base, the motors with the shielding cases are fixed above the magnet poles, two magnet poles are arranged and include thepole N and the pole S, the two magnet poles are oppositely arranged, the cylindrical mold is arranged between the magnet poles, the motors with the shielding cases drive the shielding discs to rotate,the shielding discs are arranged between the magnet poles and the cylindrical mold, the magnetic abrasive particles are arranged in the cylindrical mold, the cylindrical mold is driven by the transmission mechanism to axially rotate, the shielding discs are composed of two or more fan blades, the fan blades are axially and evenly distributed, and the fan blades of the two shielding discs are staggered. The device has the beneficial effects that the shielding discs are used for achieving alternating changing of magnetic force of magnetic fields on the two ends of the cylindrical mold, motion directions of the magnetic abrasive particles can be achieved, and the magnetic abrasive particles in the directional motion are used for finishing of a machine part.

Description

technical field [0001] The invention belongs to the field of magnetic grinding precision finishing processing, in particular to a double permanent magnetic pole alternating magnetic field magnetic grinding processing device. Background technique [0002] With the rapid development of science and technology in the world, the field of aviation and aerospace has attracted more and more attention from various countries. As one of the main components of the aero-engine, the blisk of the aero-engine is particularly important to the overall performance of the aero-engine. The blades in the blisk The surface quality is the key to its performance. In the overall blisk of the aero-engine, the surface quality and surface roughness of the blade are poor, and there will be a large flutter during use, which seriously affects the stability of the aero-engine; Higher, the surface roughness of the blade is larger, which further increases the damage of the blade, greatly increases the cost o...
