Problems solved by technology

[0004] The existing magnetorheological polishing device can change the hardness of the grinding head by changing the magnetic field strength during polishing. Due to the limitation of the structure of the magnetic field generating device, the effective polishing area of ​​the magnetic field is small, and the material removal model of the entire polishing area is fixed. Complete polishing of complex surfaces

Abstract

The invention discloses a magnetic field generator of magnetorheological polishing equipment. The magnetic field generator comprises multiple electromagnetic pole groups capable of generating gradient magnetic fields, wherein each electromagnetic pole group comprises two electromagnetic poles in opposite polarities, the electromagnetic poles constituting the multiple electromagnetic pole groups adopt triangular magnetic poles arranged annularly, and polarities of every two adjacent magnetic poles are opposite. The magnetic field generator is applied to machining of multi-degree-of-freedom moving workpieces with a magnetorheological fluid, outer surfaces of one or more workpieces can be polished simultaneously under the condition of one-time clamping, and the outer surfaces can be planes, cambered surfaces or complex cambered surfaces. Trials prove that the magnetic field generator can effectively solve the problem that complex surfaces are difficult to polish, workpiece machining procedures can be reduced, and the polishing efficiency can be effectively improved.

Description

technical field [0001] The invention belongs to a magnetorheological polishing device, in particular to a magnetic field generating device of a magnetorheological polishing device. Background technique [0002] With the continuous advancement of modern information electronics technology and optical technology, more and more ultra-smooth components are used in the IT and electronics industries, such as sapphire substrates, single crystal silicon surfaces, mobile phone back covers, etc. The processing batches of such components are large , its surface should meet the requirements of ultra-smooth, high gloss, uniform color and no scratches. At present, the grinding and polishing machines on the market all adopt the principle of plane mutual grinding. The workpiece is stuck in the center wheel and polished under the grinding action of the upper and lower polishing discs. The limitation of this polishing method is that it can only process flat surfaces, not curved surfaces such ...
