Technical scheme: for solving the problems of the technologies described above, employing technical scheme of the present utility model is:
A kind of E type core grinding device, comprise bearing, motor, screw-nut body, micro-adjusting mechanism, upright slide rail, emery wheel and dividing plate, the shell of described motor is fixed by support and nut, upright slide rail is fixed on the bearing, nut and upright slide rail be suitable, be installed on the upright slide rail, and the screw rod vertical position is constant; Described micro-adjusting mechanism comprises fine-tuning nut plate plate and trimming bolt, is provided with nut bore at the fine-tuning nut plate, and fine-tuning nut is fixed on the bearing, and trimming bolt screws in the nut bore and the bottom is pressed on the bearing; The output shaft level of described motor, emery wheel are fixed on the output shaft of motor; The dividing plate horizontal positioned is provided with open-work at dividing plate, and the width of described open-work is greater than the width of emery wheel, emery wheel be positioned at open-work under.
The lapping device of said mechanism during use, is placed on E type magnetic core on the dividing plate, and the limit pin is placed on the entity place of open-work both sides on the dividing plate, and middle pin places the open-work top, drives the emery wheel rotation when motor output shaft rotates and grinds off the purpose that the certain material of middle pin reaches grinding; The position of this dividing plate and E type magnetic core is fixed, and the length that middle pin grinds off realizes by the height of regulating electric machine; The height of motor is by the screw-nut body coarse adjustment, finely tune by fine-tuning nut mechanism, because the screw rod vertical position is constant, rotary screw can drive nut and move up and down along upright slide rail, at first the height of regulating electric machine is regulated fine-tuning nut to pressing down support with downward fine setting motor height again a little more than preset height.Adjust by thickness two sides, can effectively guarantee the height of motor.
Preferably, described screw tip is fixed with handwheel; Be the height of adjustable nut by the hand rotation handwheel.
Preferably, also be provided with through hole on the described fine-tuning nut plate, leading screw passes through hole, requires the slightly larger in diameter of through hole in the external diameter of leading screw, on the one hand is unlikely to limit leading screw and rotates, and limits on the other hand leading screw and can not produce excessive partially moving.
Preferably, described trimming bolt is hex bolts, and the bolt head of trimming bolt is provided with inner hexagonal hole; Like this can multi-faceted adjusting trimming bolt.
Preferably, this lapping device also comprises Processing Room, and the relative position of Processing Room and bearing is fixed; Be fixed with two shelves in Processing Room, dividing plate lies in a horizontal plane on two shelves.The setting of Processing Room can be avoided the chip sputter everywhere that produces in the process of lapping.
Preferably, be provided with vertical chute at the face perpendicular to the output shaft of motor, be fixed with slide plate at the shell of motor, slide plate is installed in the vertical chute; By the setting of this structure, can allow the operation of motor more stable.
Beneficial effect: the E type core grinding device that the utility model provides, by the relative altitude that emery wheel and middle pin are regulated in thick, thin two aspects, improved the yield of goods.
