Abstract
The invention discloses a crown type magnetic core grinding device, comprising a bracket, a knife rest, a cutting tool, a micro actuator, a clock gauge for measuring the change of vertical height of the bracket and the knife rest; the fixed end of the micro actuator is fixed with the bracket, and the adjusting end of the micro actuator is fixed with the knife rest; the vertical height of the knife rest relative to the bracket is adjusted; an annular horizontal support platform for bearing the side legs of a crown type magnetic core is arranged on the bracket, and the inner diameter of the annular horizontal support platform is larger than the outer diameter of the inner leg of the crown type magnetic core; and the cutting tool is arranged on the knife rest, and is positioned right under the inner side of the annular horizontal support platform. In the crown type magnetic core grinding device provided in the invention, the finish size of the middle leg is adjusted by adjusting the relative height between the bracket and the knife rest through a micromatic setting, and the adjustment height is monitored through the clock gauge so that the product yield can be efficiently improved.
Description
Technical field
The present invention relates to the miniature transformer process units, relate in particular to pin lapping device in a kind of crown type magnetic core.
Background technology
Iron oxysome magnetic core manufacture craft is similar to the ceramic product manufacture craft; Need through high temperature sintering, in sintering process, because influences such as magnetic material formula, pressed density, kiln sintering atmospheres; Magnetic core is out of shape after tending to occur sintering, bad phenomenon such as magnetic core bottom out-of-flatness.Because of magnetic core product relatively stricter to the required precision of size, must be after grinding machine grinds can finished product; For the grinding of pin limit pin in the crown type magnetic core, normally earlier the limit pin is polished, contrast pin in the pin grinding of limit again.Because present lapping device, the adjusting of relative altitude all is through manual adjustment, and the deviation of goods is bigger, influences product percent of pass, has increased production cost.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art; The present invention provides a kind of crown type magnetic core lapping device; Its mode through the fine setting knife rest is regulated relative altitude, and highly monitors regulating through amesdial simultaneously, can improve the qualification rate of product.
Technical scheme: for solving the problems of the technologies described above, employing technical scheme of the present invention is:
A kind of crown type magnetic core lapping device comprises support, knife rest, cutter, micro actuator, is used between measurement bracket and the knife rest the vertically amesdial of height change; The stiff end and the support of said micro actuator fixed, adjusted end and fix with knife rest, regulates the vertical height of knife rest with respect to support; Said support is provided with the annular horizontal support platform that is used for support crown type magnetic core limit pin, and the internal diameter of annular horizontal support platform is greater than interior pin external diameter in the crown type magnetic core; Said cutter is installed on the knife rest, is positioned under the annular horizontal support platform inboard.
The crown type magnetic core lapping device of this structure, adopt micro actuator to knife rest with respect to vertically highly the regulating of support, and use amesdial that the relative altitude of knife rest and support is changed and measure, degree of regulation and certainty of measurement all ten minutes are accurate.Because annular horizontal support platform supports the limit pin of crown type magnetic core, cutter carries out grinding to the middle pin of crown type magnetic core, and adjusting cutter like this is the relative altitude of available adjustment crown type magnetic core limit pin and middle pin with respect to the height of annular horizontal support platform; Because annular horizontal support platform is solidificated on the support, and cutter is installed on the knife rest, cutter can be converted into the height of knife rest with respect to support with respect to the height of annular horizontal support platform so again.
Preferably, said cutter is the air blowing rotary cutter, and knife rest is provided with the cutter containing cavity, and cutter is installed in the cutter containing cavity, and air inlet pipe is communicated with the cutter containing cavity through the air inlet on the knife rest sidewall.Because the material matter of crown type magnetic core is soft and need the part of grinding less, thereby can adopt this simple air blowing to drive cutter, blowing in the cutter containing cavity through air inlet pipe drives the cutter rotation the middle pin of magnetic core is carried out grinding.
Preferably, said support is provided with upright guide rail, and the slide block and the knife rest of adaptive said upright guide rail are fixed.Through the design of guide rail structure, can guarantee that knife rest can not produce skew in motion process, guarantee motion accurately, move accurate.
Preferably, said micro actuator is the spiral fine tuning structure, is similar to the moving structure of spiral micrometer.
Preferably, said amesdial is vertically installed, and stiff end and knife rest are fixed, measuring junction withstands on the support.
Preferably, said annular horizontal support platform arranged outside has annular boss, and the internal diameter of annular boss is greater than the external diameter of crown type magnetic core.Like this, in the process of grinding, can prevent that the crown type magnetic core receives frictional force to leave grinding position, cause that goods are bad.
Beneficial effect: crown type magnetic core lapping device provided by the invention, through micromatic setting regulate relative altitude between support and the knife rest adjust in the processing dimension of pin, and adjustment is highly monitored through amesdial, can effectively improve the product yield.
