Description

Tank shape FERRITE CORE grinding attachment
Technical field
The invention belongs to the auxiliary equipment technical field that ferrite production is used, be specifically related to a kind of tank shape FERRITE CORE grinding attachment.
Background technology
FERRITE CORE (Ferrit Core) is a kind of high frequency permeability magnetic material, its principle is similar to silicon steel sheet, only is used in high frequency environment, mainly makees high frequency transformer, as Switching Power Supply, line output transformer etc., to increase permeability and to improve the inductance quality.Because FERRITE CORE mainly is comprised of iron, manganese and zinc metallic element, therefore usually be referred to as manganese-zinc ferrite.On FERRITE CORE, the winding coil can be made into inductor or transformer, is widely used in instrument and meter, communication equipment, electronic product and all kinds of household electrical appliance.
The shape of FERRITE CORE is various, slightly with the shape that exemplifies as cylindricality, I-shaped, hat, single hole shape, diplopore shape, four hole shapes, E font, U font, T font, EI shape, EC shape, RM shape, PQ shape, EP shape and tank shape, etc.Wherein: tank shape FERRITE CORE is mainly used in the communications field as radar, carrier terminal equipment etc.
The version of tank shape iron oxygen magnetic core is more, but its common feature is to form and to have one to be newel for magnetic post that coil is set at middle position, for the temperature coefficient that ensures FERRITE CORE, improve DC stacked performance and control inductance value, etc., thereby need make the magnetic post retain certain air gap.
Figure 2 shows that a kind of in the structural system of tank shape FERRITE CORE, comprise FERRITE CORE body 5, this FERRITE CORE body 5 forms a coil bore 51, middle position formation in coil bore 51 has a magnetic post 511, owing in the production at FERRITE CORE body 5, being subject to process limitation, the magnetic styletable face 5111 of magnetic post 511 is concordant with the magnetic core body surface 52 of FERRITE CORE body 5, therefore in the time will forming air gap, need, by subsequent handling to 5111 grindings of magnetic styletable face, make it micro-vastly lower than magnetic core body surface 52.
Grinding method to the magnetic styletable face 5111 of magnetic post 511 in prior art mainly contains two kinds; The one, with semi-automatic mode grinding, so-called semi-automatic mode grinding is to pinch FERRITE CORE body 5 by the workman, and the magnetic styletable face 5111 of magnetic post 511 is clinged on emery wheel.There is the anxiety undermined by emery wheel in the danger that the drawback of this operating type is that labor strength is large, efficiency is low, difficult quality is controlled and be attended by operation for example workman's finger, the 2nd, with full-automatic mode grinding, so-called full-automatic mode grinding is that FERRITE CORE body 5 is fixed on the clamping device that is arranged at workbench, by corresponding on FERRITE CORE body 5 and magnetic styletable face 511 grindings to magnetic post 511 by mechanically operated emery wheel, this grinding method has certain advantage for aforesaid semi-automatic mode, but because FERRITE CORE body 5 is static, therefore, when emery wheel in the process to 5111 grindings of magnetic styletable face, linear velocity difference due to the emery wheel centerand edge, be positioned at the emery wheel center, linear velocity is lower does not even produce grinding force to magnetic styletable face 5111, thereby make the 511 upper surface out-of-flatnesses of magnetic post, the air gap formed is inconsistent, affect the military service performance of FERRITE CORE 5.
In view of above-mentioned prior art, the applicant has done useful design, has finally formed technical scheme described below, and is taking to have carried out simulated test in the applicant plant area under strict secrecy provision, and it is practicable that result proves.
