Specific embodiment

The present invention will be further described with reference to the accompanying drawings and examples.

Embodiment 1:

As shown in Figs. 1-5, a kind of rotor core means for correcting provided in this embodiment, including pedestal 1, in pedestal 1 or so Two sides are equipped with fixing piece 2, are fixed with correction station 3 two 2 upper ends of fixing piece, are equipped with and rotor core periphery in correction station 3 The through slot 4 of surface engagement, the pedestal 1 are equipped with testing rod 5, the other end and rotor core inner hole of the testing rod 5 And run through through slot 4, the lower roof plate 6 being socketed on testing rod 5 is additionally provided with above pedestal 1, the lower roof plate 6 is located at 1 liang of pedestal Between the fixing piece 2 of side, the lower lock block 7 being socketed on testing rod 5, the lower lock block 7 and through slot are fixed on the lower roof plate 6 The upper end of 4 cooperations and lower lock block 7 is located in through slot 4, is equipped on the outside of the through slot 4 of 3 upper surface of correction station more than two hydraulic Column 8 is fixedly arranged above upper plate 9 in more than two hydraulic columns 8, and the lower surface of the upper plate 9 is fixed with to be cooperated with through slot 4 Upper holder block 10, the groove 11 that cooperates with 5 upper end of testing rod is equipped on upper holder block 10.

The front and rear sides of the correction station 3 are equipped with sliding slot 12, and it is sliding that opposite can slide first is equipped in sliding slot 12 Bar 13 and the second slide bar 14,13 upper end of the first slide bar are fixed on upper plate 9, and lower end is equipped with the first bending part 15, described Second slide bar, 14 lower end is fixed on lower roof plate 6, and upper end is equipped with the second bending part 16, first slide bar 13 and the second slide bar 14 The first bending part 15 and the mutual snapping of the second bending part 16 can be passed through in opposite sliding.

The diameter of the testing rod 5 is greater than or equal to the diameter for detecting the internal diameter drift of rotor core, the correction The hardness of the outer surface of stick 5 is greater than the hardness on the surface of the inner hole of rotor core.

The diameter of the through slot 4 be less than or equal in detection rotor core outer diameter drift diameter, the through slot 4 it is interior Wall hardness is greater than the hardness of rotor core peripheral surface.

Concrete operating principle: when being corrected, device is in die opening state, and lower lock block 7 is located at the upper of through slot 4 at this time Portion, the cooperation of 5 upper end of inner hole and testing rod of rotor core, the lower end of rotor core are withstood on lower lock block 7, then upper plate 9 The effect of applied force, upper holder block 10, which moves down, withstands rotor core upper end, and rotor core is pressed under the action of upper holder block 10 Enter in through slot 4, lower lock block 7 is moved down with rotor core, when lower roof plate 6 is withstood on pedestal 1, above and below rotor core End by dieback, due to the effect of power be it is mutual, the upper end of rotor core applies great power, the lower end of rotor core at this time Just by great power, fine positioning turns rotor core inner hole shape under the action of axial ends identical parallel pressure simultaneously The verticality of sub- iron core is corrected.

It is completed when rotor core corrects, upper plate 9 moves up, and when moving to certain altitude, first positioned at side is sliding Bar 13 drives the second slide bar 14 to move upwards under raised role, since the second slide bar 14 is fixed on lower roof plate 6, lower top Plate 6 can be moved up with the second slide bar 14, when lower lock block 7 by top to 4 top of through slot when, lower lock block 7 can by rotor core from Ejection in through slot 4, device is in die opening state at this time, rotor core is taken out, then carry out the correction of next rotor core.
