Abstract
A kind of iron core and the crimp connection fixture of rotating shaft, for the assembling of the rotor of miniature motor.It includes the positioning seat (6) positioning iron core (2), the base (7) of supporting positioning seat, rotating shaft 1 is pressed into the pressure head (8) of iron core, it is characterized in that, being arranged over accommodating the heating coil (3) of iron core at positioning seat, heating coil connects the outfan of an intermediate frequency power supply.This crimp connection fixture makes iron core generate heat by sensing heating, and the shaft hole in iron core expands, and rotating shaft can be made successfully to be pressed in iron core by pressure head, and after iron core cooling, shaft hole shrinks, it is achieved iron core is reliably connected with rotating shaft.
Description
Technical field
This utility model relates to the crimp connection fixture of a kind of iron core and rotating shaft, for the assembling of the rotor of miniature motor.
Background technology
The cage-type rotor of motor is made up of iron core and rotating shaft, and the iron core of rotor is press-fited by punching, by cast aluminium cage modle around
Group is fastened, and iron core is arranged in rotating shaft, and iron core must be able to reliably transmit torque with the connection of rotating shaft, it is therefore necessary to carries
The frock being connected with rotating shaft for a kind of iron core, to ensure the quality of connection of iron core and rotating shaft.
Summary of the invention
The technical problems to be solved in the utility model is to provide the crimp connection fixture of a kind of iron core and rotating shaft, it can make iron core with
Rotating shaft connects reliable.
This utility model solves the technical scheme of technical problem, and a kind of iron core and the crimp connection fixture of rotating shaft, it includes right
The positioning seat 6 of iron core 2 location, the base 7 of supporting positioning seat, rotating shaft 1 is pressed into the pressure head 8 of iron core, it is characterized in that, in location
Seat be arranged over accommodating the heating coil 3 of iron core, heating coil connects the outfan of an intermediate frequency power supply.
The operation principle of this crimp connection fixture is, heating coil produces an exchange flux after connecting intermediate frequency power supply, and this magnetic flux leads to
Crossing the rotor core in heating coil, form eddy current, make iron core generate heat in rotor core, the shaft hole in iron core expands, energy
Making rotating shaft be successfully pressed in iron core by pressure head, after iron core cooling, shaft hole shrinks, it is achieved iron core is reliably connected with rotating shaft.
It provides the benefit that: this crimp connection fixture will not make rotating shaft and shaft hole grind compared with cold extrusion connected mode
Damage；The device preventing iron core and rotating shaft to be axially moveable can be saved compared with bonded mode.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view of heating coil.
Accompanying drawing mark represents respectively: 1-rotating shaft, 2-iron core, 3-heating coil, 4-the first joint, 5-the second joint, 6-are fixed
Position seat, 7-base, 8-pressure head, 9-support, 10-insulation sleeve, 61-outer shroud, 62-core.
Detailed description of the invention
In conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
A kind of iron core and the crimp connection fixture of rotating shaft, including positioning seat 6, pressure head 8, the center of positioning seat and pressure head center are one
On axis, positioning seat is used for positioning iron core, and the cross section of positioning seat is E font, and its core 62 is provided with through hole, the outer shroud of positioning seat
The inner circle of 61 matches with the cylindrical of iron core, and the core of positioning seat is recessed, and the bottom of iron core is shelved on the top of core, positioning seat
It is fixed on base 7；Pressure head is used for rotating shaft 1 is pressed into iron core.
Positioning seat be arranged over heat coil 3, heating coil first joint the 4, second joint 5 be provided with insulation sleeve
10, insulation sleeve is connected with support 9, and support is fixed on base；First joint the 4, second joint 5 of heating coil connects intermediate frequency power supply
Outfan.During during use, iron core is placed in heating coil, the magnetic flux that heating coil produces induces eddy current in the core makes iron core
Heating, uses the mode of sensing heating can make the homogeneous temperature of iron core each several part.
The external diameter of described rotating shaft is more than the internal diameter of the shaft hole of iron core, and its difference is 0.03-0.05 millimeter, heats coil
Induction heating temperature to iron core is 200 DEG C-250 DEG C (this temperature is reached by the output voltage of regulation intermediate frequency power supply), this
Sample can make rotating shaft reduce friction between the two when being pressed into iron core, and iron core temperature can closely be received when being reduced to below 90 DEG C
Contracting is in rotating shaft, it is achieved iron core is reliably connected with rotating shaft.
Described heating coil copper pipe or stainless steel tube are coiled into, and so can pass to cool down water in heating coil, it is to avoid
Heating coil damages because temperature is too high.
