Technical field
The present invention relates to a kind of rotor core fixed structure for motor rotor core riveting device, belong to motor rotor core preparing technical field.
Background technology
Motor (Electric machinery, is commonly called as motor) refers to a kind of calutron of realizing electric energy conversion or transmit according to the law of electromagnetic induction.In circuit with the old standard D of alphabetical M() represent.In general, the machine that motor is is kinetic energy transformation of electrical energy, it is the electric rotary machine rotatablely moving and the reciprocable machine that is straight reciprocating motion transformation of electrical energy that such motor can be divided into transformation of electrical energy.Motor is arranged on the nearly all product using in the families such as refrigerator, air-conditioning, washing machine, electric fan and dust catcher as power source.
Since 19th century invention electric rotating machine, the agent structure of motor and use material do not have essential change, generally stator, rotor and other annex, consist of.Traditional motor rotor is comprised of rotating shaft and rotor core, the two ends of rotating shaft bearing is housed so that rotor rotational support on motor casing, the conventional mild steel of rotating shaft is made.Rotor core structure as shown in Figures 1 and 2, by the superimposed rear rotor core body forming of the circular silicon steel sheet with grooved hole, the permanent magnet being fixed in slotted eye forms with the counterweight cover that is sealed on rotor core body two ends, counterweight cover is referring to shown in accompanying drawing 3 and accompanying drawing 4, its structure is a donut, the limit of this annulus is provided with arc-shaped convex, is also provided with the hole of allowing that rivet passes on annulus.
Rotor core, in manufacturing process, need to be riveted on two counterweight covers on the two ends of iron core body with rivet.Therefore be necessary to design a kind of rotor core fixed structure for motor rotor core riveting device.
Summary of the invention
The object of the invention is to provide a kind of rotor core fixed structure for motor rotor core riveting device.
For achieving the above object, the technical solution used in the present invention is: a kind of rotor core fixed structure for motor rotor core riveting device, comprise that a cross section is circular mount pad, and it is in circular installation sleeve that this mount pad is slidably arranged in a cross section; Described mount pad offers a plurality of blind holes and a plurality of mount pad through hole by bottom surface to end face; The bottom of described installation sleeve is provided with capping, and the corresponding described mount pad lead to the hole site of this capping is provided with capping through hole; In described a plurality of blind hole, be provided with support spring so that described mount pad is supported in described capping; The end face of described mount pad is provided with circular arc cutaway so that the end face of described mount pad is stepped.
Preferred technical scheme is: the end face center of described mount pad is provided with rotor core reference column.
Preferred technical scheme is: described a plurality of blind holes are symmetrical arranged, and described a plurality of mount pad through holes are symmetrical arranged; Described blind hole and mount pad through hole interval arrange.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
