Motor manufacturing assembly technology is the important ring in entire manufacturing industry for electrical machine, and rational technique can not only improve
Labor productivity, energy saving and raw material, additionally it is possible to promote product competitiveness, increase economic efficiency.At present, large-size machine is fixed
Many assembly technologies of sub- iron core are completed by manual and worker's experience, and q＆r is difficult to be guaranteed.By
This to the assembly technology in large-size machine manufacturing process as it can be seen that optimized particularly important meaning and engineering application value.
Specifically, industrial motor is generally made of components such as engine base, end cap, stator, rotors, and usual assembling stator is using cold
Stator is pressed into motor case or by stator on casing hot jacket by the mode of pressure or hot jacket, and stator passes through interference fit with casing
Mode be combined together, then rotor is put into, end cap is closed on both sides, is fastened by screw, formed motor complete machine.
The process of the assembling of motor of the prior art is more, and cumbersome installation step directly affects productivity effect, system
The about cost of motor.After installing motor stator using modes such as tradition cold pressing hot jackets, motor is dismantled in inconvenience, once hair

The process structure of motor case is also an important factor for influencing motor quality.Industrial motor casing generally use cast iron
Material or casting aluminium material.Cast iron casing is usually used in that build is larger, the motor of heavier-weight, but cast iron density is larger, weight itself
It is heavier, it is not suitable for the motor required for main screw lift, such as electric motor of automobile, pump motor.Cast aluminium casing is usually used in weight
The motor limited is measured, but since casting aluminium material is rigidly relatively low, engine base footing cannot support heavier weight, load outputs
End cap can not bear higher output torque.The conduct vibrations of cast aluminium casing are high simultaneously, easily make electric motor end cap, footing
Resonance occurs, is deformed, influences motor operation quality.And it can be increased using rare metal class alloy material cheap
The manufacture cost of industrial motor, therefore usually only with cast iron or casting aluminium material.

Structure is the motor housing structure in above-described embodiment.Setting is convenient for mounting and dismounting motor in this way.
In the present embodiment, motor further includes stator department 50 and rotor portions 60.Stator department 50 is set in accommodation space.Turn
Sub-portion 60 is set in stator department 50, and the both ends of the shaft 61 of rotor portions 60 are worn from the first axis hole 11 and the second axis hole 21 respectively
Go out.Setting is convenient for being assemblied in stator department 50 and rotor portions 60 are more firm in motor housing structure in this way.
In the prior art, there are following defects for industrial motor：
It installs tedious process, inefficiency constrains motor cost, and it is more difficult that industrial motor tears machine open, is broken
Bad property is dismantled, and is not easy to the maintenance overhaul of motor, is influenced the detection and analysis of failure.The size that each parts of motor cooperate
It is more, it needs the critical size processed more, influences motor production.Motor case material cannot take into account that quality is smaller and rigidity simultaneously
The advantages of higher, large-size machine casing generally use cast iron materials, heavier-weight, transportation cost is high, while constrains motor
Field of employment.
In order to solve the above-mentioned technical problem, the motor housing structure of the application using include first shell, second shell and
The set-up mode of latch assembly 30.Wherein, be machined with guide rail in second shell, during installing with the guide rail in first shell into
Row cooperation.When assembling motor, stator, rotor, second shell are installed successively.When installing second shell, by second shell along
In the guide rail press-in first shell of first shell, the coaxial of motor front and back bearings is ensured by the guide rail of front and rear part, locking flange
Degree.After second shell is installed in place, bolt fastening is reused, ensures that casing installation is close, and the Number of Bolts used with this
Amount is also reduced to original half.When dismantling motor, by unclamping fastening bolt, second shell is released into first shell, you can
Complete rotor component is obtained, step is easy, will not generate destruction to structure member.
Using the motor in the present embodiment, installation flow can be simplified, reduces installation material variety, improves motor
Manufacturing process efficiency；Motor easy to disassemble simultaneously, convenient for checking electrical fault and repair, the critical size that motor needs are processed
It reduces.Second shell uses casting aluminium material, and first shell uses cast iron materials, and the installation rigidity and load for both having ensured motor export
The support stiffness at end, and motor overall weight is reduced, extend motor application place.
When casing is processed, since the machined surface of required processing is all in one side, whole can be processed on clamped one time
Size avoids secondary clamping, ensures machining accuracy.First shell, the processing dimension of second shell are consistent simultaneously, clamping shape one
It causes, therefore processing method shares, and can be processed on same lathe with identical manufacturing procedure, avoids replacing processing mold, carry
High processing efficiency and precision.Critical size is installed for the depth of parallelism and first shell, the second shell of bearing chamber and guide rail platform
Guide rail, the size for locking flange.The fit dimension of the two is respectively the length of length L1, width H1 and guide rail for locking flange
L2, width H2.Wherein H1 and H2 is using the fit tolerance for being interference fitted U7/h7, to ensure that stator will not generate shifting in motor
Position；L1 and L2 coordinates the fit tolerance of H7/m6 using transition, to ensure that guide rail can avoid generating completely into locking flange
Axial displacement.And original some critical sizes such as first end cover, second end cover is matched with engine base junction second shell and iron core
Become non-key size at conjunction etc., it is no longer necessary to higher machining accuracy, it is only necessary to carry out roughing, it is ensured that do not interfere motor
Installation, so as to reduce at least five precision machined size of processing needs, effectively improve production efficiency.
On material, second shell uses casting aluminium material, and first shell uses cast iron materials, if front and rear part casing respectively accounts for casing
The 50% of total volume, the averag density of cast iron materials is 7.8x103kg/m3, the averag density of casting aluminium material is 2.7x103kg/
m3, compared with cast iron casing, the accounting Δ η of casing gross weight reduction is：
Therefore consider from weight, 30% or so casing gross weight can be reduced using combined housing case.And in rigidity, due to
The cast iron materials that its footing, load end end cap portion still use, therefore it is installed rigidity and runs rigidity and former full cast iron materials
Casing is consistent.Thus not only reduce motor gross weight but also maintain original motor rigidity.
Such design can effectively improve the final assembly efficiency of industrial motor, simplify installation flow, so as to reduce electricity
The manufacture of intraocular cost of machine.The dismounting of each parts of motor is facilitated, convenient for the detection and analysis of electrical fault.Simultaneously because first
Housing and second shell are not only reduced overall weight, but also maintain higher installation rigidity, are extended electricity using different materials
The field of employment of machine.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
