The center of the rotor mounting base is provided with a rotating shaft placing hole. A punch is disposed, corresponding to the upper part of the rotor mounting base, and the center of the punch is provided with a rotating shaft receiving hole. The punch is provided with a punching work part, which is concentric to the rotating shaft receiving hole and has a cross section in the shape of a circular ring. The rotor core and rotating shaft mounting and reinforcing apparatus is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to a kind of rotor core rotating shaft bracing means is installed, and belongs 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 utility model electric rotating machines, the agent structure of motor and use material there is no essential change, is generally made up of stator, rotor and other annex.Traditional motor rotor is made up 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 is by the superimposed rear rotor core body forming of the circular silicon steel sheet with grooved hole, and the permanent magnet being fixed in slotted eye forms with the counterweight cover that is sealed on rotor core body two ends.
Rotor is in manufacturing process, rotating shaft adopts the mode of interference assembling to be assembled in the shaft hole of rotor core, but this interference fit stability or poor, is therefore necessary to design a kind of rotor core rotating shaft bracing means is installed, to reinforce the annexation of rotating shaft and rotor core.
Utility model content
The utility model object is to provide a kind of rotor core rotating shaft bracing means is installed.
For achieving the above object, the technical solution adopted in the utility model is: bracing means is installed in a kind of rotor core rotating shaft, comprises a workbench, and this workbench is provided with rotor holder; The center of described rotor holder is provided with rotating shaft placed hole; The top correspondence of described rotor holder is provided with drift, and the center of this drift is provided with rotating shaft reception hole; Described drift is provided with the press work portion that the cross section concentric with described rotating shaft reception hole is annulus.
Preferred technical scheme is: the interior diameter of a circle of the press work portion that described cross section is annulus is greater than the diameter of rotating shaft.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
1, the root of press work portion's punching press electronics iron core of the present utility model and rotating shaft junction, thus make the fixed relationship of rotating shaft and rotor core more stable.
2, the utlity model has advantage simple in structure, easy to operate.
Accompanying drawing explanation
Accompanying drawing 1 is bracing means schematic diagram.
In above accompanying drawing, 1, workbench; 2, rotor holder; 3, rotating shaft placed hole; 4, drift; 5, rotating shaft reception hole; 6, press work portion; 7, rotating shaft; 8, rotor core.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Notice, appended graphic the illustrated structure of this description, ratio, size etc., all contents in order to coordinate description to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this description, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
Embodiment: bracing means is installed in a kind of rotor core rotating shaft
Shown in accompanying drawing 1, bracing means is installed in a kind of rotor core rotating shaft, comprises a workbench 1, and this workbench 1 is provided with rotor holder 2; The center of described rotor holder 2 is provided with rotating shaft placed hole 3; The top correspondence of described rotor holder 2 is provided with drift 4, and the center of this drift is provided with rotating shaft reception hole 5; Described drift 4 is provided with the press work portion 6 that the cross section concentric with described rotating shaft reception hole 5 is annulus.Described cross section is the diameter that the interior diameter of a circle of the press work portion 6 of annulus is greater than rotating shaft.
Using method: the rotor after interference is assembled is placed on rotor holder 2, insert the rotating shaft placed hole 3 of rotor holder 2 with the rotating shaft 7 of rotor core 8 one end, then starting punch press moves down drift 4, the rotating shaft 7 of the other end of rotor core 8 enters in the rotating shaft reception hole 5 of drift 4, drift 4 continues to move down, the root of the junction of press work portion 6 to rotor core 8 and rotating shaft 7 extruding, makes rotor core 8 tighter with being connected of rotating shaft 7.
Above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
