Abstract
A crimping tool of an iron core and a rotation shaft is used for assembling a rotor of a small-size electric motor. The crimping tool comprises a positioning seat (6), a base (7) and a press head (8), wherein the positioning seat (6) is used for positioning the iron core (2), the base (7) is used for supporting the positioning seat, the press head (8) is used for pressing the rotation shaft 1 into the iron core, the crimping tool is characterized in that a heating coil (3) is arranged on the positioning seat and can be used for accommodating the iron core, and the heating coil is connected with an output end of a medium-frequency power supply. In the crimping tool, the iron core generates heat by induction heating, a rotation shaft hole in the iron core is expanded, the rotation shaft can be smoothly pressed into the iron core by the press head, the rotation shaft hole contracts after the iron core is cooled, and the reliable connection of the iron core and the rotation shaft is achieved.
Description
Technical field
The present invention 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, the iron core of rotor is press-fited by punching, fastened by cast aluminium cage modle winding, iron core is arranged in rotating shaft, iron core must be able to reliably transmit torque with the connection of rotating shaft, it is therefore desirable to providing the frock that a kind of iron core is connected with rotating shaft, to ensure the quality of connection of iron core and rotating shaft.
Content of the invention
The technical problem to be solved in the present invention is to provide the crimp connection fixture of a kind of iron core and rotating shaft, and it is reliable that it can make iron core be connected with rotating shaft.
The present invention solve technical problem technical scheme be, a kind of iron core and the crimp connection fixture of rotating shaft, it includes the base 7 to iron core 2 positioning seat 6 positioning, supporting positioning seat, the pressure head 8 being pressed into rotating shaft 1 in iron core, it is characterized in that, it is provided with the heating coil 3 that can accommodate iron core above positioning seat, heating coil connects the output end 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, this magnetic flux passes through the rotor core in heating coil, form vortex in rotor core, iron core is made to generate heat, the shaft hole in iron core expands, and rotating shaft can be made successfully to be pressed in iron core by pressure head, after iron core cooling, shaft hole shrinks, and realizes being reliably connected of iron core and rotating shaft.
Its advantage is：This crimp connection fixture will not make rotating shaft and shaft hole wear and tear compared with cold extrusion connected mode；The device preventing iron core and rotating shaft to be axially moveable can be saved compared with bonded mode.

Fig. 2 is the top view of heating coil.
Accompanying drawing mark represents respectively：1- rotating shaft, 2- iron core, 3- heating coil, 4- first joint, 5- second joint, 6- positioning seat, 7- base, 8- pressure head, 9- support, 10- insulation sleeve, 61- outer shroud, 62- core.
Specific embodiment
Specific embodiment in conjunction with the brief description present invention.
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 on an axis, positioning seat is used for iron core is positioned, and the section of positioning seat is E font, and its core 62 is provided with through hole, the inner circle of outer shroud 61 of positioning seat is matched with the cylindrical of iron core, the core of positioning seat is recessed, and the bottom of iron core is shelved on the top of core, and positioning seat is fixed on base 7；Pressure head is used for rotating shaft 1 is pressed in iron core.
It is provided with heating coil 3 above positioning seat, the first joint 4 of heating coil, the second joint 5 are provided with insulation sleeve 10, and insulation sleeve is connected with support 9, and support is fixed on base；First joint 4 of heating coil, the second joint 5 connect the output end of intermediate frequency power supply.During use, iron core is placed in heating coil, and the magnetic flux that heating coil produces induces vortex in the core makes iron core generate heat, and the temperature of iron core each several part can be made by the way of sensing heating uniform.
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, and heating coil is 200 DEG C -250 DEG C to the induction heating temperature of iron core（This temperature is reached by adjusting the output voltage of intermediate frequency power supply）, rotating shaft so can be made to be pressed into during iron core and to reduce friction between the two, iron core temperature can closely be contracted in rotating shaft when being reduced to below 90 DEG C, realize being reliably connected of iron core and rotating shaft.
Described heating coil copper pipe or stainless steel tube are coiled into, and so can pass to cooling water in heating coil, it is to avoid heating coil is damaged because temperature is too high.
Claims (3)
