Description
Technical field
The invention belongs to magneto field, more particularly to magneto rotor magnetizing test device and its technique.
Background technology
Current magneto rotor is first carried out to rotor with magnet charger generally using magnetizing and testing two operations completing
Magnetize, then the performance that magnetizes of rotor is tested with testboard so that production line layout station is many, operation work step is numerous
Trivial, efficiency is low, particularly magnetize performance can not disposably qualified in the case of, be necessary for taking out magneto from testboard and turn
Son, returns on magnetized head and magnetizes again, virtually so that work step becomes complicated, can also overcome to do over again and magnetize during artificial operation
Operation, in automatic assembly line, is most difficult to realization and does over again operation of magnetizing.Also the method design having by test surfaces magnetic flux now
Magnetize the frock of test, due to rotor production rigging error be inevitably, the rotation axis of rotor magnetic pole and rotor axle sleeve
Misaligned, the air gap that will result directly between stator and rotor is inconsistent, due to air energy magnetic conduction, so as to affect the trend of magnetic circuit,
Final magneto generating voltage will be affected, the method by surveying surface magnetic flux, and rotor surface magnetic flux is consistent, qualified
, judge to send qualified voltage by testing result, but the inconsistent voltage of the air gap in practice between stator and rotor subtracts
Few, it is qualified to generate detection, using underproof abnormal conditions, make detection in principle just with physical presence difference, it is impossible to
Ensure the uniformity of product.Test of magnetizing is carried out to product, surface magnetic flux is carried out to rotor after magnetizing and tests, which is not enough
Part is that measurement condition is inconsistent with magneto applying working condition, and inconsistent with using result using test result, causing can not
Meet the requirement of actual test, there is larger deviation.
Content of the invention
An object of the present invention is to provide a kind of simple structure and magneto rotor automatic magnetism-charging test easy to use
Device, it can solve to produce line length, are not easy to the propulsion for automating, reduce production process, reduce labour intensity, save production
Cost, is to realize automation mechanized operation to provide necessary infrastructure device.
The purpose of the present invention employs the following technical solutions realization, and it includes live spindle, fills magnetic test coil and work
Station, wherein, by the vertical installation of bearing on the table, the upper and lower side of live spindle all stretches out workbench to live spindle,

The lower end of live spindle is also inherently located at the positioning chuck below fifth wheel, is provided with horizontally disposed in the side of positioning chuck
And retractable locking pin, the axial line of locking pin is perpendicular with live spindle, is provided with just to locking pin on positioning chuck
Locking hole, locking hole are matched with locking pin.
Can be magnetized power supply using magnet charger in said structure, electric cabinet can be fixed on the table, electric cabinet
Voltmeter is connected on magnetic test coil, and the output end of magnet charger is connected with magnetic test coil is filled, the fifth wheel of live spindle with dynamic
Power machine connects, and engine can adopt the output shaft of motor, motor to form power connector, rotation master by belt and fifth wheel
Axle is stopped in specified location and by locking pin locked, the keyway of the keyway alignment live spindle of magneto rotor axle sleeve is put well,
And make to fill magnetic test coil and be located at corresponding with the magnet of magneto rotor in magneto rotor, startup magnet charger is to test of magnetizing
Coil power supply, by magnetic test coil to magnetizing, after the completion of magnetizing, closes magnet charger, and control locking pin exits positioning chuck
On locking hole, then automatic or manual start motor, make live spindle rotate, live spindle drive magneto rotor rotation,
Treat that magneto rotor reaches high-speed rotation state, generating voltage test entered, voltage draws magnitude of voltage after voltmeter test,
Result according to test is compared, if qualified, shut down, removes rotor, if unsaturated (test voltage is low) is magnetized, then
Restarting magnet charger carries out secondary magnetizing to rotor so as to reach Eligibility requirements, if super-saturated (test voltage is higher),
Then magneto rotor is demagnetized, magnetized after demagnetization again to qualified.Magnetize and test and realize all on same device, reduce magnetic
Rotor magnetization and unnecessary all swivel links in test process, shorten production line, are easy to the propulsion for automating, hence it is evident that subtract
Production process is lacked, efficiency has been improve, labour intensity has been reduced, production cost has been saved, be to realize automation mechanized operation to provide
Necessary infrastructure device.
The second object of the present invention is to provide one kind to magnetize method of testing, and it will magnetize and tests the technique two of two kinds of operations
Unification, reduces operation, improves efficiency.
1) worktable rotary main shaft is stopped in specified location, and locking pin is inserted locking in the hole and live spindle is locked
Tightly；
2) will be bonded in live spindle for the magneto rotor that need to be magnetized；
3) start magnet charger to magnetic test coil energising is filled, fill magnetic test coil and produce magnet of the magnetic field to magneto rotor
Magnetized；
4) test phase is immediately entered after the completion of magnetizing, and first opens the locking pin of locking live spindle, meanwhile, start power
Machine work makes live spindle drive magneto rotor to reach high-speed rotation state, enters generating voltage test, and voltage is through overvoltage
Magnitude of voltage is drawn after table test；
5) compared according to the result of test, if qualified, shut down, remove rotor；If test voltage is low, i.e.,
Magnetize unsaturation, repeat the 3rd), 4) step, until qualified；If test voltage is higher, over-saturation of magnetizing, then carry out demagnetization behaviour automatically
Make, after demagnetization, repeat the 3rd), 4) step, magnetized to qualified again.
Eliminated by said method and product is flowed between magnet charger and testboard repeatedly, strong so as to save work
Spend, saved the production time and automated production is carried out there is provided necessary basis for production line.Because rotor test be into action
State is tested, and measurement condition is consistent with applying working condition.So as to not conforming to for avoiding because measurement condition and applying working condition are inconsistent, produce
It is unqualified that the Product checking of lattice is that qualified, qualified product is detected as so that properties of product cannot get due guarantee.
Due to employing technique scheme, the present invention has the advantages that simple structure and easy to use, and it can shorten
Production line, eliminates product and is magnetizing and unnecessary all swivel links in test process, hence it is evident that reduces production process, reduces labor
Fatigue resistance, has saved production cost, is easy to the propulsion for automating, and is to realize automation mechanized operation to provide necessary infrastructure device.
