Description
Technical field
The present invention is relevant with grinding machinery, is meant a kind of magnetic grinder especially.
Background technology
Magnetic grinder commonly used is bulletin case numbers No. 143109 for example, its principle is that work package and some magnetic abrasive materials are positioned in the storage tank, utilize an alternating magnetic field generation device, the side produces an alternating magnetic field at the bottom of this storage tank, to respond to these magnetically grinding medium motions, make these magnetically grinding media fully collide, rub, to reach the effect of removing work package burr and surface grinding; Yet this alternating magnetic field is to produce side at the bottom of this storage tank, and its intensity is upwards successively decreased gradually from this storage tank bottom, makes these magnetically grinding media for elongated workpiece, can't reach complete grinding effect in the place's motion of the close bottom surface of this storage tank; Secondly, magnetic grinder commonly used produces the mode of alternating magnetic field, is to utilize a magnetic part, it has most permanet magnets, respectively this magnetite is to be staggered with the N utmost point, the S utmost point, the N utmost point, the S utmost point to produce magnetic field, utilizes a motor to turn this magnetic part magnetic field and produces staggered the variation, forms an alternating magnetic field.Yet this kind design needs to use most permanet magnets, and it is higher to expend cost, and the long-time use of permanet magnet also the situation that magnetic weakens can occur; Moreover, utilize a motor to turn magnetic part, relate to the moving part running, the long-time anxiety that the moving part wearing and tearing are arranged of using.
In view of this, the utility model creator thinks funiculus through detailed, and the long-pending research and development experience of being engaged in relevant industries for many years, and generation of the present invention is arranged eventually.
The utility model content
Be to provide a kind of magnetic grinder, be one its magnetic field intensity not to be changed with its storage tank degree of depth main order of the present invention.
Main purpose of the present invention is to provide a kind of magnetic grinder, is a simple structure, cheap for manufacturing cost and long service life.
For reaching above-mentioned purpose, a kind of magnetic grinder, it includes: a shell has a storage tank; Some magnetic conduction abrasive medias are placed in this storage tank; One alternating magnetic field generation device is to include a bobbin winder bracket and a coil groups, and this bobbin winder bracket is located in this shell and around the periphery of this storage tank; This coil groups is to be set around this bobbin winder bracket and the plurality of coils that forms with enamel-covered wire; Whereby, can produce an alternating magnetic field after this coil groups energising, and can respond to these magnetic conduction abrasive media motions.
Whereby, work package can be placed this article putting groove and collision, the friction of these magnetically grinding media to reach the effect of grinding and polishing and removal burr.

The specific embodiment
Please consult Fig. 1 earlier to shown in Figure 4, a preferred embodiment of the present invention provides a kind of magnetic grinder, and it includes:
One shell 10, its end face is recessed to form a storage tank 11 toward body portion, and its bottom is provided with a pedestal 12 to be positioned on ground or the workbench, and this pedestal 12 can be in order to ccontaining other members, as control circuit, electronic component etc.
Some magnetic conduction abrasive medias 20 as stainless steel needle-like body, are placed in this storage tank 11.
One alternating magnetic field generation device is to include a bobbin winder bracket 30 and a coil groups 40, wherein:
This bobbin winder bracket 30 is that the silicon steel sheet by majority is laminated, and is positioned at this shell 10 and around the periphery of this storage tank 11, the medial margin of this bobbin winder bracket 30 has most axial grooves 31.
This coil groups 40, be to pass wantonly two these grooves 31 back and forth to be wound on this bobbin winder bracket 30 with enamel insulated wire, and form one first, 1 second, one tertiary coil 41,42,43 in regular turn, and respectively this coil 41,42,43 is divided into two parts, radially be disposed at respectively on these bobbin winder bracket 30 relative positions, can form the magnetic field that penetrates this bobbin winder bracket 30 respectively after making these each coil 41,42,43 energisings, the N in these magnetic fields, the S utmost point point to can be according to the right-hand rule, by these each coil 41,42,43 winding directions and sense of current decision.
The above, the composition member explanation for preferred embodiment of the present invention then further specifies its operation principle again.
One work package (not shown) is inserted in this storage tank 11, one three-phase alternating-current supply, have one first, 1 second and one third phase P1, P2, P3, import this first, second and third coil 41,42,43 respectively, this three-phase alternating-current supply is the string waveshape, and have the phase difference of 120 degree between each phase P1, P2, P3, alternately produce magnetic field in regular turn so as to making this first, second, third coil 41,42,43, and form an alternating magnetic field (as shown in Figure 6); These magnetic conduction abrasive medias 20 are subjected to magnetic field induction, and generation motion in this storage tank 11 along with the variation of this alternating magnetic field, because the weight of these magnetic conduction abrasive medias 20 is light more than work package, it collides with work package in the high-speed mobile process fully, friction, reaches good grinding effect whereby.
Can learn by the foregoing description, the advantage of magnetic grinder of the present invention is, utilize a coil groups to drive, alternately produce the magnetic field of different directions, and form an alternating magnetic field with a three-phase alternating-current supply, its simple structure and nothing turn moving part, so it is purchased, maintenance cost reduces relatively, has industrial utilization, simultaneously because the running of no moving part, do not have the noise that motor drives, member rotates the vibrations generation during running, can effectively reduce the noise content of grinding work; Secondly, alternating magnetic field is that the periphery by storage tank applies, and does not influence grinding effect with elevational change, therefore can have the better grinding effect to microscler work package.
In addition, also can in article putting groove 11, insert a movable grinding groove again, work package and these magnetic conduction abrasive medias 20 are inserted in this grinding groove, to make things convenient for waste disposal, abrasive media to change or change fast and treat the grinder workpiece, also can add lapping liquid to help heat radiation, to clean to avoid the distortion of sharp impacts generation work package.
The above only is a preferable possible embodiments of the present invention, so the equivalent structure that all application specification of the present invention and claim are done changes, ought to be included in the claimed scope of patent of the present invention.
