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 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 ceramic product manufacture craft, need to pass through high temperature sintering, in sintering process, due to impacts such as magnetic material formula, pressed density, kiln sintering atmospheres, the bad phenomenon such as after tending to occur sintering, magnetic core is out of shape, magnetic core bottom out-of-flatness.Because of magnetic core product stricter to the required precision of size, must can finished product after grinding machine grinds; For the grinding of pin limit pin in crown type magnetic core, normally first limit pin is polished, then contrast pin in the pin grinding of limit.Due to present lapping device, the adjusting of relative altitude is all by manual adjustment, and the deviation of goods is larger, affects product percent of pass, has increased production cost.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of crown type core grinding device, its mode by fine tuning tool rest regulates relative altitude, and by amesdial, to regulating, highly monitors 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 core grinding device, comprises support, knife rest, cutter, micro actuator, for measuring between support and knife rest the vertically amesdial of height change; Stiff end and the support of described micro actuator fixed, adjusted end and fix with knife rest, regulates the vertical height of knife rest with respect to support; On described support, be provided with the annular horizontal support platform for support crown type magnetic core limit pin, and the internal diameter of annular horizontal support platform be greater than crown type magnetic core in pin external diameter; Described Cutting tool installation manner, on knife rest, is positioned under annular horizontal support platform inner side.
The crown type core grinding device of this structure, employing micro actuator cutter setting frame vertically highly regulates with respect to support, and uses the relative altitude variation of amesdial cutter setting frame and support to measure, and degree of regulation and certainty of measurement are all very 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 like this cutter 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 support, Cutting tool installation manner is on knife rest again, and cutter can be converted into the height of knife rest with respect to support with respect to the height of annular horizontal support platform like this.
Preferably, described cutter is air blowing rotary cutter, is provided with cutter accommodating cavity on knife rest, and Cutting tool installation manner is in cutter accommodating cavity, and air inlet pipe is communicated with cutter accommodating cavity by the air inlet on 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, by air inlet pipe, to blowing in cutter accommodating cavity, drive cutter to rotate the middle pin of magnetic core is carried out to grinding.
Preferably, on described support, be provided with upright guide rail, slide block and the knife rest of adaptive described upright guide rail are fixed.By the design of guide rail structure, can guarantee that knife rest can not produce skew in motion process, guarantee motion accurately, accurately mobile.
Preferably, described micro actuator is spiral fine tuning structure, is similar to the moving structure of spiral micrometer.
Preferably, described amesdial is vertically installed, and stiff end and knife rest are fixed, measuring junction withstands on support.
Preferably, described 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 crown type magnetic core is subject to frictional force to leave grinding position, cause that goods are bad.
Beneficial effect: crown type core grinding device provided by the invention, by micromatic setting regulate relative altitude between support and knife rest adjust in the processing dimension of pin, and highly monitor adjusting by amesdial, can effectively improve product yield.
