Problems solved by technology

[0004] However, the magnetorheological polishing equipment invented by COM of the University of Rochester has certain defects. First, there are certain limitations on the size of the workpiece to be processed.
Since the magnetic field of the equipment is fixed, the relative motion between the workpiece and the magnetorheological polishing fluid is mainly formed by the rotating motion of the workpiece above and the flow of the magnetorheological polishing fluid, so it is difficult to achieve a relatively large processing size. The workpiece, the processing diameter is generally only a few tens of millimeters
Secondly, there are certain restrictions on the shape of the workpiece to be processed.

Embodiment Construction

[0015] Describe the present invention below in conjunction with accompanying drawing:

[0016] Such as figure 1 with figure 2 As shown, the orthogonal axis combination magnetic polishing tool is disc-shaped, and the yoke 1, the magnetic isolation plate 3, the wheel core sleeve 4, the wheel core 5 and the magnet 2 are tightly connected together by the magnetic force of the magnet.

[0017] Magnetic spacer 3 is the disc-shaped magnetic spacer with holes in the middle, and magnet 2 is a sector magnet, which is evenly distributed on the middle part of magnetic spacer 3 both sides along the circumference. The magnet can be a permanent magnet or an electromagnet. The N pole of the magnet on one side of the magnetic separation plate is on the outer circumference, and the S pole of the magnet on the other side is on the outer circumference; on the outer circumference of the magnetic separation plate 3 both sides, the magnetic force of the magnet fixes two annular yokes 1; Two ring-...

Abstract

The normal axis combined magnetic polishing equipment belongs to a precision curved surface machining tool field, and includes magnetic yoke, magnetic iron and magnetic isolation board, the describedmagnetic polishing tool is made into the form of circular disk. It also includes wheel core cover and wheel core, the magnetic isolation board is circular disk magnetic isolation board whose centre has a hole, the described magnetic iron is uniformly distributed on the central portion of two sides of magnetic isolation board along the periphery, the N pole of magnetic iron of one side of the magnetic isolation board is mounted on the external periphery, and S pole of anoter side magnetic iron is mounted on the external periphery, two ring magnetic yokes are fixed on the external peripheries of two sides of the magnetic isolation board by means of magnetic force.

Description

technical field [0001] The invention belongs to the field of precision curved surface processing tools. Background technique [0002] Magnetorheological polishing (MRF) technology is a very novel grinding and polishing technology. Magnetorheological polishing uses the rheological properties of magnetorheological polishing fluid in a magnetic field for polishing. In a high-intensity gradient magnetic field, the magnetorheological polishing fluid hardens, becomes a viscoplastic Bingham medium, and forms protrusions. When such protrusions come into contact with the surface of the workpiece, a large shear force is generated on the area of ​​the workpiece surface in contact with it, thereby removing material from the surface of the workpiece. Magnetorheological fluid (MR Fluid) is a non-colloidal suspension formed by dispersing micron-sized magnetic particles in an insulating carrier liquid. A certain proportion of grinding and polishing abrasives are mixed into the magnetorheol...
