Description
Technical field：The present invention relates to the processing of shielding motor rotor retaining ring and mounting process.
Background technology：With various insulation, conductive, permeability magnetic material development, the motor size of large-scale power is smaller and smaller
Type, especially shield electric machine need to meet the flow field cycle between stator and rotor and require simultaneously, this requires that shield electric machine
Some interior parts must be in defined a certain space, and the retaining ring on rotor is exactly wherein one, it is located at hot jacket at copper end
On ring, and wrapped up by retaining ring.If this thin-walled parts are simply processed on lathe, wanted it is difficult to meet required size
It asks.
In to past large-size machine maintenance process, it has been found that copper end ring and rotor bar couples in rotor
Part is easy expanded by heating, and local buckling is easy tod produce under the action of electromagnetic torque or even is produced fracture, and motor is caused to lose
Effect.Some large-size machine manufacturing enterprises take on electric machine end ring that hot jacket retaining ring is to reduce copper end ring expanded by heating, simultaneously
Make copper end ring uniform force to reduce the risk of local deformation or fracture.
Invention content：The object of the present invention is to provide a kind of processing of shielding motor rotor retaining ring and mounting process, solutions
Problem difficult, more than outfit is installed in the processing of retaining ring of having determined difficulty, improves retaining ring processing, installation quality, while also improving
Production efficiency reduces tool number, to reducing cost.
Technical scheme is as follows：Shielding motor rotor retaining ring is processed and mounting process：
A. size：Ring forging is kept to process one end end face and outer circle on lathe；
B. it is assembled in tire：Retaining ring (1) is installed on the carcass (2) of the retaining ring machining mould of preparation, passes through spiral shell
(4) fastening is followed closely to compress the retaining ring (1) of small pressing plate (3) below；
C. turning inner hole：By on retaining ring machining mould clamping to lathe, smart car endoporus；
D. inner hole grinding：By on retaining ring machining mould clamping to grinding machine, inner hole grinding；
E. hot jacket：Retaining ring (1) after processing is installed in retaining ring hot jacket tool (8), and with retaining ring hot jacket work
Have (8) and be sent into heating in stove together, when ring (1) to be held reaches furnace setpoint temperatures, after held for some time, by retaining ring
(1) it hangs out, is placed on rotor fixed frame (9) out of stove, the rotor sling is inserted into retaining ring hot jacket tool (8), directly
Until rotor tooth support (5) is contacted with the locating piece (7) on hot jacket tool (8) top, after ring cooling to be held, retaining ring is removed
Hot jacket tool (8), and rotor is transported to lathe；
F. size：By on the rotor clamping to lathe of hot jacket retaining ring, centering, processing are carried out by the centering band of rotor
Retaining ring (1) outer circle reaches the requirement of excircle configuration size.
In step a at clamping retaining ring (1) on lathe, the clamping force of scroll chuck should not be too large, and by retaining ring
Retaining ring machining mould inner circle 0.05mm-0.10mm in the turning of outer circle allowance to less than step b, and in retaining ring machining mould
Multiple grooves are equipped at circle.
It is an advantage of the invention that：1, retaining ring belongs to thin-walled parts, and rotor retaining ring in process, is needed with preparation
Retaining ring machining mould, the clamping deformation for preventing retaining ring can be conducive to, while retaining ring machining mould also acts as transhipment
Tool also reduces the deformation during transhipment and storage；2, grinding process is increased, grinding improves the table of retaining ring inner circle
Surface roughness increases the stability of fiting property, and since surface roughness is higher, the Wave crest and wave trough value of microcosmic surface is smaller,
Effective contact area is big, and wave crest, which is not easy to squeeze, puts down, and actually active interference volume is consistent with theoretical calculation interference volume, to stabilize
Bond strength；3, during hot jacket, because it is thin-walled parts, rapid heat dissipation during individually being taken out out of stove after heating, temperature
It reduces, thermal expansion amount is reduced, and the risk for causing to scrap should not be inserted in or do not covered there are retaining ring.Increase retaining ring hot jacket work
Have (8), and heated with stove with retaining ring, this ensure that during pickup and hot jacket centering, heat is unlikely to radiate
Soon, to increase the success rate of hot jacket.Retaining ring hot jacket tool is equipped with locating piece, and conducts oneself with dignity by rotor, by retaining ring heat
It is set on rotor.4, retaining ring outer circle is processed after retaining ring hot jacket to rotor copper end ring, is mould by rotor
Retaining ring outer circle is processed, the Excircle machining sequence for adjusting retaining ring is last sequence.It will afterwards assemble and draw this avoid first processing
The deformation that excircle dimension is generated by hot jacket is played, this deformation is unfavorable for the quality of the assembly and product of later other parts, very
Interfere to generating.
Description of the drawings
Fig. 1 is to maintain ring and is put into retaining ring machining mould schematic diagram.
Fig. 2 is to maintain ring hot jacket station schematic diagram.
Specific implementation mode
A. size：Operator gets holding ring forging, and after being recorded to forging mark, and ring forging will be kept to use
Three-jaw chuck supports inner circle on vertical vehicle, and the active force of three-jaw chuck should not be too large at this time, and best condition is found by end face and end face,
Turning one end end face and turning, outside diameter should be less than retaining ring machining mould inner circle 0.05mm-0.10mm；
B. it is assembled in mould：As shown in Figure 1, downward by the end face of retaining ring turning, being installed to the holding of preparation
In the carcass 2 of ring machining mould, is fastened by screw 4 and compress the retaining ring 1 below small pressing plate 3；
C. turning inner hole：By on retaining ring machining mould clamping to lathe, by the outer circle and end face centering of retaining ring to most
Good state, it is unilateral to stay certain grinding allowance, turning inner hole, chamfering, and turning other end, ensure length to drawing requirement ruler
It is very little.Inspector verifies processing dimension；
D. inner hole grinding：After lathe process is complete, bed of going round and round a millstone, by retaining ring machining mould clamping to grinding machine chuck, to protect
After held in ring inner circle and end face centering to best condition, the internal diameter size and surface roughness that are ground to drawing requirement are carried out；
E. hot jacket：After inspector checks size qualification, as shown in Fig. 2, retaining ring is split out from retaining ring machining mould, clearly
It after reason is clean, attaches it in retaining ring hot jacket tool 8, adjusts locating piece 7, stove is hung in retaining ring hot jacket tool 8
It is inside heated, heating temperature to set temperature, after held for some time, retaining ring 1 is hung out out of stove, and be placed into rotor
On fixed frame 9, and the rotor sling is inserted into retaining ring hot jacket tool 8, until on rotor tooth support 5 and hot jacket tool 8
Until the locating piece 7 in portion contacts, after ring cooling to be held, retaining ring hot jacket tool 8 is removed, and rotor is transported to lathe；
F. size：By on the rotor clamping to lathe of hot jacket retaining ring, centering processes retaining ring excircle configuration size
To drawing requirement.
