Description
Technical field
The utility model relates to a kind of assembly toolings of motor rotor core.
Background technique
Usual motor rotor core is inserted in machine shaft by the segmentation of iron core hub bore, and is interference fit.As shown in Figure 1,
11 inner wall of hub bore of rotor core 1 is circumferentially spaced equipped with lightening hole equipped with the keyway 12, end face cooperated with machine shaft
13, it is easy in the assembly of rotor core and machine shaft to misalign due to the axis of rotor core and the axis of machine shaft, lead
Cause rotor core cannot smoothly be packed into, or by power of enforcement indentation, due to use pressing tool diameter of bore than rotor iron
The hub bore diameter of core is big, may cause when being packed into rotor core and occurs apparent warpage at iron core hub bore, leads to rotor c.g.
Radial deflection, to influence the behavior in service of motor.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of assembly tooling of motor rotor core, this toolings gram
The defect for taking conventional rotors iron core and machine shaft assembly, can make rotor core smoothly be packed into shaft, avoid iron core hub bore warpage
Caused rotor c.g. offset, improves assembly efficiency, it is ensured that the behavior in service of motor.
In order to solve the above technical problems, the assembly tooling of the utility model motor rotor core includes ring flange, cylindrical sleeve
With several tooth connections, the cylindrical sleeve with being located in the flange disc side, and the cylindrical sleeve and ring flange diameter of bore with
Rotor core hub bore diameter is consistent, and the cylindrical sleeve and ring flange inner hole wall are equipped with keyway, and several connection spaces of teeth are set to
Cylindrical sleeve end face outer ring.
Further, the cylinder jacket wall is axially spaced is equipped with several grooves, and the groove is between adjacent tooth connection.
Further, the groove is 4~8.
Since the assembly tooling of the utility model motor rotor core uses above-mentioned technical proposal, i.e. this tooling includes method
Blue disk, cylindrical sleeve and several tooth connections, cylindrical sleeve with being located in ring flange side, and cylindrical sleeve and ring flange diameter of bore with turn
Sub- iron core hub bore diameter is consistent, and cylindrical sleeve and ring flange inner hole wall are equipped with keyway, and several connection spaces of teeth are set to cylindrical sleeve end face
Outer ring.The defect that this tooling overcomes conventional rotors iron core and machine shaft to assemble, can make rotor core smoothly be packed into shaft, avoid
The offset of rotor c.g. caused by iron core hub bore warpage, improves assembly efficiency, it is ensured that the behavior in service of motor.
Detailed description of the invention
The utility model is described in further detail with embodiment with reference to the accompanying drawing：
Fig. 1 is rotor core structure schematic diagram；
Fig. 2 is the assembly tooling structural schematic diagram of the utility model motor rotor core；
Fig. 3 is the application schematic diagram of this assembly tooling.
Specific embodiment
Embodiment is as shown in Fig. 2, the assembly tooling of the utility model motor rotor core includes ring flange 2,3 and of cylindrical sleeve
Several tooth connections 4, the cylindrical sleeve 3 is same to be located in 2 side of ring flange, and 2 diameter of bore of the cylindrical sleeve 3 and ring flange
Consistent with rotor core hub bore diameter, the cylindrical sleeve 3 and 2 inner hole wall of ring flange are equipped with keyway 21, between several tooth connections 4
Every set on the 3 end face outer ring of cylindrical sleeve.
Preferably, 3 wall of cylindrical sleeve is axially spaced is equipped with several grooves 31, and the groove 31 is located at adjacent tooth connection
Between 4.When rotor core and machine shaft assemble, since this tooling and machine shaft are close-fitting, it is not easy to Assembly And Disassembly,
Therefore this tooling is while with good rigidity, it is also desirable to have certain toughness and deformability, pass through several grooves
Contraction and expansion can facilitate disassembly of this tooling in assembly.
Preferably, the groove 31 is 4~8.
As shown in figure 3, machine shaft 5 is carried out cold treatment first, then in machine shaft 5 when rotor core 1 assembles
Tail end installs magnetic isolation plate 6, flat key 7 is placed in the keyway of machine shaft 5, before one section of rotor core 1 is then inserted in machine shaft 5
The keyway at end, rotor core 1 is directed at flat key 7, using 3 end face of cylindrical sleeve of this tooling against rotor core 1,3 end face of cylindrical sleeve
Several tooth connections 4 protrude into the lightening hole of 1 end face of rotor core, to guarantee the radial positioning of this tooling, the keyway pair of cylindrical sleeve 3
The keyway of quasi- rotor core 1, guarantee is circumferentially positioned, so that it is guaranteed that the axis centering of the axis of this tooling and rotor core 1, at this
2 end face of ring flange of tooling applies the uniform pressure along axis, and rotor core 1 is slowly pushed, until this section of rotor core 1 with
Magnetic isolation plate 6 abuts；Then this tooling is exited along machine shaft 5, during which several grooves of 3 wall of cylindrical sleeve are by shrinking and expanding
Realize this tooling along the advance and retreat of machine shaft 5；Similarly, each section of rotor core of residue is successively pressed into machine shaft 5.At last
After section rotor core indentation machine shaft 5, machine shaft 5 restores to room temperature, at this time machine shaft 5 and each section of rotor core 1 it
Between realize interference fit, outermost layer rotor core 1 will not be after dismantling this tooling to loosening outside.Finally before machine shaft 5
Another magnetic isolation plate is installed at end, is applied an axial force with end face of the modes such as fastening bolt to magnetic isolation plate, is guaranteed that each section turns
It is permanent impaction state between sub- iron core 1, completes the assembling work of entire rotor core.
