The purpose of this utility model provides a kind ofly to be improved structure on the basis of prior art, increased disk suction, with this suction replacement pressure roller and other clamping device that the workpiece handle is tight, avoid surface of the work scuffing, impression, distortion, the many windings that improve product quality and production efficiency circular ring type multipolar electromagnetic sucker.
Above-mentioned purpose realizes by following technical scheme:
Many windings circular ring type multipolar electromagnetic sucker, its composition comprises: be fixed on the many winding electric magnet that is made of interior iron core, interior loop, outer iron core connecting plate, shell on the equipment body and be installed in circular ring type disk on the main shaft, the magnetic pad is fixed on the circular ring type disk, between described interior loop and described shell, be evenly distributed with one group of outer iron core, be wound with exterior loop on the described outer iron core.
Above-mentioned many windings circular ring type multipolar electromagnetic sucker, described circular ring type disk comprises outer disk and interior disk, described outer disk is a closed round ring, endoporus has one group of fan-shaped shrinkage pool, the external diameter of disk has one group of fan-shaped flange in described, is provided with non-magnetic conduction division board between described fan-shaped shrinkage pool and the sidewall that described fan-shaped flange contacts.
Above-mentioned many windings circular ring type multipolar electromagnetic sucker, described magnetic pad comprises backing plate and base, the two makes the one framework, and its magnetic pole is the N utmost point, leaves clip slot on described framework, described clip slot place is welded with the pole plate of band base, its magnetic pole is the S utmost point, and described framework and described pole plate constitute three groups of pole pairs, and the crevice place between described framework and the described pole plate is provided with non-magnetic conduction division board, be covered with coating around described each magnetic pole of base, described coating is that nickel and nano rare earth material are composited.
This technical scheme has following beneficial effect:
1. the utility model is on the basis of prior art structure to be improved, the simplex winding electromagnet is designed to many winding electric magnet, the direct respectively and circular ring type disk coupling of the pole pair of many winding electric magnet (N, S), the magnetic field intensity that records is approaching, compare the pole pair (N, S) of simplex winding electromagnet, the magnetic field intensity that records differs more than one times.
2. prior art adopts resolution formula disk, and dynamic and static magnet coupling is discontinuous, only is 50% of unity couping, the magnetic circuit magnetic resistance increases, and N, S pole piece divide two layers of combination in the formula of the resolution disk, and 50% space is filled up by stainless steel, not only leakage field is big, and complex process, cost height.The utility model is designed to closed outer disk with original open outer disk, when the outer iron core connecting plate 13 of the outer magnetic pole S of the outer disk of closure and many winding electric magnet when closely (about 0.3mm) is relative, because magnetic circuit path is short directly, dynamic and static magnet coupling continuously, and effectively coupling area improves 50% than prior art, the magnetic circuit magnetic resistance reduces greatly, and magnechuck obviously increases the suction of workpiece, can be up to 16～25kg.It is firm that the assurance workpiece is stablized in process, and the magnetic coupling effect is remarkable thus.
3. with base plated with nickel on the magnetic pad and nano rare earth material composite bed, this composite bed makes magnetic advance capital for body have good wearability, so claim essential wear-resisting type magnetic pad, and existing technology needs to clamp the several piece alloy block at magnetic pad end face, increased magnetic resistance, simultaneously, end face in use is difficult for keeping its flatness, scratches workpiece easily.
4. the magnetic field distribution of the utility model on three pairs of magnetic poles (N, S) is even, demonstrates fully the characteristics of multipolar electromagnetic sucker, and promptly magnetic line of force major part is inhaled face by workpiece, has reduced leakage field.After the completion of processing, degaussing easily makes workpiece not have remanent magnetism, guarantees the inherent quality of workpiece.
5. the utility model is difficult for scratching workpiece because suction face is level and smooth, because magnetic line of force major part is inhaled face by workpiece, the workpiece machined surface does not have magnetic, metal can not cut to be drawn onto to cause on the machined surface scratching, and guarantees the presentation quality of workpiece.
