Abstract
The invention discloses a processing method of a stator core of a permanent magnet synchronous motor. The method is characterized by comprising the following steps of: carrying out overlaying processing on the stator core; putting the stator core into an oven, heating the stator core to 200 DEG C and carrying out heat preservation for 2.5h; hoisting a rotating shaft into refrigerating equipment, refrigerating the rotating shaft to 120 DEG C and carrying out heat preservation for 25min; taking out the stator core from the oven, putting the stator core at the center of an oil press, and quickly sleeving the rotating shaft with the core and pressurizing the core in place if necessary; arranging a welding arc key and a key; and hot sleeving support plates at two ends of the core and welding the support plates. According to the processing method of the stator core of the permanent magnet synchronous motor disclosed by the embodiment of the invention, the problem of the processing quality of the core is relatively well solved; and the processing method completely conforms to the technical requirements on the product design and the technology, and has very good practicability.
Description
Technical field
The present invention relates to new-energy automobile manufacturing technology field, the processing method particularly relating to the stator core of a kind of permagnetic synchronous motor.
Background technology
Along with the extensive application of rare-earth permanent magnet material-Ru-Fe-Mn alloy, magneto is developed rapidly because it has the advantage such as simple in construction, reliable, small in volume, can be widely used for new-energy automobile field.At present, the processing method of the stator core of magneto is badly in need of improving.
Summary of the invention
For solving the problems referred to above present in prior art and practical situation, the processing method that the invention provides the stator core of a kind of permagnetic synchronous motor, it is characterised in that comprise the steps:
Stator core is laminated process；
Stator core is put in baker and be heated to 200 oC, it is incubated 2.5h；
Rotating shaft is hung in freezing equipment and is refrigerated to-120oC, is incubated 25min；
Stator core is taken out from baker, is placed in hydraulic press center, rotating shaft is inserted in rapidly iron core simultaneously, can pressurize if desired and put in place；
Join welding arc key and key；
Hot jacket iron core two ends gripper shoe is also welded.
Preferably, the described step that stator core laminates process specifically includes:
It is 3MPa that setting laminates pressure, pressurizes at twice, is laminated to 400mm and pressurizes once, and final repressurization is once.
Beneficial effect:
The processing method of the stator core of a kind of permagnetic synchronous motor that the embodiment of the present invention provides, the problem preferably solving iron core crudy, comply fully with in product design and technologic technology requirement, very practical.
Detailed description of the invention
Technical solution of the present invention is described in detail below.
Embodiments of the invention disclose the processing method of the stator core of a kind of permagnetic synchronous motor, and the method comprises the steps:
Stator core is laminated process；Stator core is put in baker and be heated to 200 oC, it is incubated 2.5h；Rotating shaft is hung in freezing equipment and is refrigerated to-120oC, is incubated 25min；Stator core is taken out from baker, is placed in hydraulic press center, rotating shaft is inserted in rapidly iron core simultaneously, can pressurize if desired and put in place；Join welding arc key and key；Hot jacket iron core two ends gripper shoe is also welded.Further, the described concrete steps that stator stands up process include: stator turning supporter is placed on stator non-transmision end, after adjusting position, fixing-stable；After support bar is passed total dummy shaft end suspension ring, support bar is placed in support slot；Sling stator from driving end, make stator non-transmision end down, remove support bar.
Stator core uses outer press mounting structure.Laminate employing monolithic construction expander, technique controls laminate pressure and dwell time to guarantee to set up suitable pole sheet pressure.Stator sleeve uses freezing for iron core heating rotating shaft simultaneously, after moisturizing a period of time, first iron core is pulled out baker and is placed on poppet, then carries out the technique that freezing rotating shaft directly hangs in.After it cools down, then welding arc keying is fixed.
Further, the described step that stator core laminates process specifically includes:
It is 3MPa that setting laminates pressure, pressurizes at twice, is laminated to 400mm and pressurizes once, and final repressurization is once.
The processing method of the stator core of a kind of permagnetic synchronous motor that the embodiment of the present invention provides, the problem preferably solving iron core crudy, comply fully with in product design and technologic technology requirement, very practical.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
