Embodiment 1
The present embodiment provides a kind of fixing meanss of magnet steel, wherein, along the axial direction of rotor core 1, the length of magnet steel groove 11
More than the length of magnet steel 2, comprise the steps：
S1：Magnet steel 2 is embedded in the magnet steel groove 11 of rotor core 1, the both ends of the surface of magnet steel groove 11 are corresponding with the two ends of magnet steel 2
End face between form the groove 6 caving inward respectively, preferably the depth of two grooves 6 is consistent, for example, the depth of groove 6
It is preferably 1mm；
Anaerobic adhesive 3 is injected in the gap being formed between the side wall and the internal face of magnet steel groove 11 of magnet steel 2, for example, excellent
Happy safe 545 anaerobic adhesives of choosing, along the axial direction of rotor core 1, length after magnet steel 2 is in place for the anaerobic adhesive 3 being applied is less than magnet steel 2
Length is so that form the first gap between the side wall at the two ends of magnet steel 2 and the internal face of magnet steel groove 11；
S2：First fill UV glue into the first gap, then fill UV glue by the groove 6 at magnet steel groove 11 both ends, and make
The outer surface of UV glue is concordant with the end face of rotor core 1, and makes UV adhesive curing with ultraviolet irradiation simultaneously, and the UV glue after solidification will
Anaerobic adhesive 3 in magnet steel groove 11 is isolated from the outside, and anaerobic adhesive 3 solidifies magnet steel 2 is adhesively fixed with magnet steel groove 11.
The fixing meanss of the magnet steel in this embodiment, first insert magnet steel 2 in magnet steel groove 11, will be big in magnet steel groove 11
Partial air discharge magnet steel groove 11, the side wall of backward magnet steel 2 and magnet steel groove 11 internal face between formed gap in injection
Anaerobic adhesive 3, the air in this gap is discharged magnet steel groove 11, anaerobic adhesive 3 by the side wall of magnet steel 2 and magnet steel groove 11 internal face it
Between carry out pre-glued, more first into the first gap, fill UV glue, the air in the first gap all discharged, UV glue solidifies rapidly
Make not containing air in the first gap, and form enclosed environment, anaerobic adhesive 3 rapidly solidifies under this enclosed environment, by magnet steel 2
Bonding firm between magnet steel groove 11；Meanwhile, after filling UV glue in the first gap, then fill UV glue into groove 6, between first
After UV adhesive curing in gap and groove 6, itself also serve as bonding agent, further the both ends of magnet steel 2 are adhesively fixed on magnetic
On steel tank 11 internal face, shorten time magnet steel 2 being fixed in magnet steel groove 11, improve production efficiency.
As the alternative embodiments of UV glue, above-mentioned UV glue can be replaced instant drying adhesive 403, instant drying adhesive 406, instant drying adhesive
410th, instant drying adhesive 414 etc., time of its condensation cure generally in seconds, or of the prior art coagulates rapidly at normal temperatures
Other quick-drying gelatins of knot solidification, can also be other fluid sealants of the prior art, as long as being poured in the two ends end surface of magnet steel 2
On, form closing space with magnet steel groove 11 after its solidification, anaerobic adhesive 3 can be solidified rapidly under no oxygen environment, by magnet steel 2
Bonding with magnet steel groove 11 firmly.In addition, it is necessary to explanation, above-mentioned UV glue, need could be solidified with ultraviolet light,
Other fluid sealants need to be according to the performance of itself, and the adaptively step of increase sealing glue solidifying condition, if fluid sealant is no special
When different condition just can solidify, just only fluid sealant need to be poured on the both ends of magnet steel 2.
As the deformation of anaerobic adhesive 3, except safe 545 anaerobic adhesives of the above-mentioned pleasure being given, can also for 6.9 anaerobic adhesives, 680 detest
Which kind of anaerobic adhesive other anaerobic adhesives 3 of the prior art of oxygen glue, 638 anaerobic adhesives etc., specifically adopt, need to be according to actually used feelings
Depending on condition.
As the alternative embodiments of S2 step, in S2 step, first into the first gap, fill UV glue, then by magnet steel
UV glue is filled, the outer surface of the UV glue in injection groove 6 can not be with the end face of rotor core 1 in the groove 6 at groove 11 both ends
Concordantly, can project in groove 6, or not fill up groove 6, the fluid sealant that only need to inject can form closing by magnet steel groove 11
Space is so that anaerobic adhesive 3 is isolated from the outside.
As the interchangeable embodiment of S1 step, in S1 step, the end face of magnet steel groove 11 is corresponding with magnet steel 2
End face between form the groove 6 caving inward, the other end is concordant with the corresponding other end of magnet steel 2, now to groove 6 He
Fluid sealant is irrigated on the other end of magnet steel 2, fluid sealant fills up groove 6, and desired thickness is irrigated on the other end of magnet steel 2
Fluid sealant, thus the both ends of magnet steel groove 11 are closed, formed closing space.
As the interchangeable embodiment of S1 step, in above-mentioned S1 step, the anaerobic adhesive 3 being applied is in place in magnet steel 2
Length afterwards is less than the length of magnet steel 2, it is also possible that shape between the side wall of one end of magnet steel 2 and the internal face of magnet steel groove 11
Become the first gap, the other end with place after anaerobic adhesive 3 end face concordant, only need to be by the in place rear anaerobic adhesive 3 in magnet steel groove 11
Two ends air discharge, formed oxygen-free environment, promote anaerobic adhesive 3 fast setting.
As interchangeable embodiment further, can also be without arranging the first above-mentioned gap, after anaerobic adhesive 3 is in place
Length is consistent with the length of magnet steel 2, directly irrigates fluid sealant in the two ends groove 6 of magnet steel groove 11.
As interchangeable embodiment further, can also be without arranging above-mentioned groove 6, magnet steel groove 11 and magnet steel 2
Length is consistent, in S1 step, after magnet steel 2 is inserted in magnet steel groove 11, directly to magnet steel groove 11 and magnet steel 2 side wall it
Between gap in inject anaerobic adhesive 3, directly on the end face at the both ends of magnet steel 2, irrigate fluid sealant afterwards, sealing glue solidifying makes
Anaerobic adhesive 3 in magnet steel groove 11 is isolated from the outside, anaerobic adhesive 3 solidifies magnet steel 2 and magnet steel groove 11 is adhesively fixed.
For example, when injecting anaerobic adhesive 3 in directly to the gap between magnet steel groove 11 and magnet steel 2 side wall, fluid sealant has
Part note is on the end face of rotor core 1, bonding with the end face seal of magnet steel 2 by the end face of rotor core 1, forms magnet steel groove 11
Interior enclosed environment, anaerobic adhesive 3 is in enclosed environment and carries out fast setting.
In addition, as preferred embodiment, in above-mentioned S1 step, it is preferred to use magnet steel 2 is inserted by existing frock
Predetermined position in magnet steel groove 11, or arranged using other or by the way of artificial insert magnet steel 2 in magnet steel groove 11.With
When, it is preferred to use anaerobic adhesive 3 is expelled to the gap between magnet steel 2 side wall and magnet steel groove 11 internal face by needle tubing according to aequum
Interior, it is easy to control the injection rate of anaerobic adhesive 3.As deformation, other injection devices of the prior art or coating can also be adopted
Device, only need to inject anaerobic adhesive 3 in the gap between magnet steel 2 side wall and magnet steel groove 11.
In addition, for the depth of groove 6, the depth of groove 6 can also for 0.5mm, 0.6mm, 0.8mm, 1.2mm,
1.4mm, 1.6mm, 1.8mm, 2mm etc., depending on the depth of groove 6 also needs according to actually used situation.Similarly, for first
For the length in gap, the first gap is preferably 1mm, or 0.5mm, 1.5mm etc., and the length of concrete setting is in addition it is also necessary to root
