Punching of inner rotor punching plates is carried out by a multi-station progressive die; cable point laminating and riveting of a plurality of inner rotor punching plates are finished on blanking, laminating and riveting stations; the flatness of the inner rotor core is ensured by rotating a certain angle along the same direction in the laminating process; and finally the side surface of a laminated cylinder is glued to bond a magnetic shoe to form the inner rotor core.
Description
Technical field
The present invention relates to a kind of internal rotor iron core of brushless electric machine and the lamination adhesive method of internal rotor iron core, belong to motor processing and manufacturing field.
Background technology
Motor rotor core is the rotating parts in motor, and for realizing the conversion between electric energy and mechanical energy, and rotor core is the cylinder be laminated by several identical rotor punchings.The manufacture method of conventional rotors iron core first goes out rotor punching, stacked on special equipment by some rotor punching finish layers and press-fit, make it to become rotor core.The method needs point multistep to carry out, and complex process, production efficiency is low.
Summary of the invention
The invention provides a kind of internal rotor iron core of brushless electric machine, coordinate outer Wound-rotor type stator core to use.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of internal rotor iron core of brushless electric machine, the internal rotor punching identical by several shapes is laminated cylinder, each internal rotor punching center is provided with shaft hole, shaft hole surrounding is dispersed with equally spaced even number through hole, button point is laid between adjacent through hole, the excircle of internal rotor punching equidistantly lays fin, and fin quantity is consistent with number of openings, and each button point is all on the line between the center and the center of circle of shaft hole of fin; The magnetic shoe that cylindrical side bonds is consistent with the number of openings in internal rotor punching, each magnetic shoe is between adjacent fin, and neighbouring internal rotor punching carries out folded riveting by button point.
The basis of such scheme is arranged further:
The shape of described through hole is pentagon.
Described button point is made up of rectangle cramp and rectangle button hole, cramp be connected with internal rotor punching and downward-sloping, its excess-three limit disconnect.
The cramp at the internal rotor punching button point place on described upper strata embeds in the button hole of internal rotor punching correspondence button point of lower floor.
Described number of openings is identical with the number of poles of motor.
The present invention also provides the closed assembly method of above-mentioned internal rotor iron core simultaneously, and the progressive die tool comprising employing multistation completes the punching of the shaft hole of internal rotor punching, through hole, cylindrical, button point shape successively; Automatic laminating after the punching of every sheet internal rotor all rotates miter angle along equidirectional when blanking; Form cylinder after riveting is folded in the internal rotor punching meeting setting requested number, cylinder is taken out from mould, at cylindrical sides gluing and bonding magnetic shoe forms internal rotor iron core.
When in the closed assembly method of above-mentioned internal rotor iron core, the button point of internal rotor punching carries out punching, only three of cramp limits are thrust, residue still keeps connecting on one side, but to when being positioned at the button point punching of the undermost internal rotor punching of internal rotor iron core, four of cramp limits are thrust completely, do not retain cramp, only form button hole.
Internal rotor iron core provided by the present invention, is formed from fold button by the internal rotor punching adopting progressive die tool to be once washed into, ensure that the stacked precision of internal rotor iron core; Be located at the fin on internal rotor punching excircle, be conducive to location during magnetic tile pasting, effectively ensure that magnetic shoe is evenly distributed on internal rotor iron core; Internal rotor punching rotates to an angle when stacked blanking, ensures the flatness of internal rotor iron core.
Below by way of the drawings and specific embodiments, the present invention is further elaborated.
accompanying drawing illustrates:
Fig. 1 is internal rotor iron core transverse cross section structure schematic diagram of the present invention.
embodiment:
Shown in composition graphs 1, a kind of internal rotor iron core of brushless electric machine, the internal rotor punching identical by several shapes is laminated cylinder, each internal rotor punching center is provided with shaft hole 1, and shaft hole 1 surrounding is dispersed with equally spaced even number through hole 2, and the quantity of through hole 2 is identical with the number of poles of institute's use motor, in the present embodiment, motor is eight grades of motors, then through hole 2 is set to eight, the shape of through hole 2 is pentagon, and the setting of through hole 2 is the moment of inertia in order to reduce internal rotor iron core; Button point 3 is laid between adjacent through hole 2, as the punching of multi-disc internal rotor mutual stacked time carry out the folded riveting point that fastens each other, button point 3 can be circular or rectangle, when button point 3 is rectangle, button point 3 is made up of rectangle cramp and rectangle button hole, cramp while be connected with internal rotor punching, its excess-three limit disconnect; The excircle of internal rotor punching equidistantly lays fin 5, and fin 5 quantity is consistent with through hole 2 quantity, and the setting of fin 5 is location when conveniently the assembling of internal rotor iron core is pasted magnetic shoe 4; On the line of each button point 3 all between the center of fin 5 and the center of circle of shaft hole 1; The magnetic shoe 4 that cylindrical side bonds is consistent with through hole 2 quantity in internal rotor punching, each magnetic shoe 4 is between adjacent fin 5, neighbouring internal rotor punching carries out folded riveting by button point 3, and namely the cramp at internal rotor punching button point 3 place on upper strata embeds in the button hole of internal rotor punching correspondence button point 3 of lower floor.
The closed assembly method of the internal rotor iron core in such scheme, comprises and adopts the punching that the progressive die tool of multistation completes the shaft hole 1 of internal rotor punching successively, through hole 2, cylindrical, button put 3 shapes; Automatic laminating after the punching of every sheet internal rotor all rotates miter angle along equidirectional when blanking, to ensure the whole flatness of internal rotor iron core; After riveting is folded in the internal rotor punching meeting setting requested number, form cylinder, cylinder is taken out from mould, at cylindrical sides gluing and bonding magnetic shoe 4 finally forms internal rotor iron core.
When in the closed assembly method of above-mentioned internal rotor iron core, the button point 3 of internal rotor punching carries out punching, only three of cramp limits are thrust, residue still keeps connecting on one side, but when 3 punching is put to the button being positioned at the undermost internal rotor punching of internal rotor iron core, four of cramp limits are thrust completely, do not retain cramp, only form button hole, facilitate the cramp at internal rotor punching button point 3 place on upper strata to insert in the button hole of lower floor.
Above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, other amendments that those of ordinary skill in the art make technical scheme of the present invention or equivalently to replace, only otherwise depart from the spirit and scope of technical solution of the present invention, all should be encompassed in right of the present invention.
