Description
Technical field
The present invention relates to a kind of DC pump motor rotor and seal the method for fixing cord, be used for the lead fixed of DC pump motor.
Background technology
DC pump motor is the power source of hydraulic system hydraulic pumps such as lifting device, walking machine such as vehicular hydraulic elevator platform, hydraulic pressure fork truck, dump truck, automobile tail.4.5 the inch serial motors is the maximum motor of current needs amount, the rotor of existing motor is an open slot on the market, and the lead in the rotor adopts the artificial bonding fixed form of groove encapsulating of pounding.There is the illusive phenomenon of bonding in this method of operation, and when motor ran up, outer layer conductor was thrown out of outside the iron core slot easily, the causes motor cisco unity malfunction.And this process can cause production efficiency low.
Existing 4.5 inches DC pump motors, the fixing of rotor wire undertaken by following operation:
1. pound groove: after the embedding of rotor line is good, successively lead loose in each groove is beaten shaping, make its tight arrangement, and be lower than the iron core cylindrical with the special correcting circuit chi.Because be manual operations, the rotor number is many again, lead produces resilience in operating process; Though each groove has all been carried out shaping; But lead often has the phenomenon that exceeds iron core, and this method of operation also easily because of human factor causes coil short and coat of paint breakage, hidden danger of quality occurs.
2. the preparation before the encapsulating: with 60～70 ℃ of 1h of rotor preliminary drying.
3. encapsulating: three components of the glue epoxy resin of fixing cord in 10: 1: 1 ratio proportionings, and are stirred.The glue for preparing is contained in the funnel shaped instrument, and the lead in each groove is carried out encapsulating, requires glue-line to exceed lead, and is lower than the iron core surface.Owing to be the artificial visual method of operation, there is bakie and encapsulating situation not in place, the amount of glue also is difficult to control; Cause the lead illusive phenomenon that bonds easily, when motor rotation, lead exceeds the iron core cylindrical; With the stator inner hole friction, rupture, cause serious quality accident.
4. dry: as after the rotor behind the encapsulating placed 1～2h naturally, to toast 3h at 55～65 ℃.The restriction that this mode is serious production, suitable motor is produced in enormous quantities.
Summary of the invention
The technical problem that solves
For fear of the weak point of prior art, the present invention proposes the method that a kind of DC pump motor rotor is sealed fixing cord, has solved rotor fishing line problem, has improved the security reliability of production efficiency and motor operation.
Technical scheme
A kind of DC pump motor rotor is sealed the method for fixing cord, it is characterized in that step is following:
Step 1: partly process three mounting holes in rotor end plates and punching yoke, three mounting holes evenly distribute for 120 °, and the mounting hole center line overlaps with punching tooth center;
Step 2: at sealing device configuration calibration positioning fixture, the calibration positioning fixture is provided with three waist shape alignment pins, and the center is the iron core hole; 120 ° of described three waist shape alignment pins evenly distribute, and the distance in the waist shape alignment pin and the center of circle equals the distance in the processed epitrochanterian mounting hole and the center of circle, and the width of waist shape alignment pin equals the width of mounting hole;
Step 3: three waist shape alignment pins on the calibration positioning fixture are inserted in the processed epitrochanterian mounting hole, be configured to then on the servomotor transmission mechanism of sealing device;
Step 4: on the shaping jig of sealing device, inlay three round punch, every slot seal dashes counts by iron core slot length direction three places that distribute, and spacing equates;
Step 5: after the equipment starting, the shaping jig is introduced in the groove, and lead precompressed shaping is put in place, and three drifts contact punching both sides notch again, round punch after the oil cylinder application of force is clamp-oned punching 0.6mm is wide in the groove, 1mm is dark, seals lead.
The width of said mounting hole is 5mm.
The width of said waist shape alignment pin is 5mm.
Beneficial effect
A kind of DC pump motor rotor that the present invention proposes is sealed the method for fixing cord, and 4.5 inches rotor conductor size are 2.24mm, and after 0.6mm was respectively enclosed in both sides, the notch surplus size was 1.3mm, and lead is blocked, and lead can not throw away during motor rotation.Alleviated working strength of workers, the product quality problem of also having avoided human factor to cause by this method processing, has compressed the production cycle of rotor significantly, has improved effect.Solve rotor fishing line problem, improved the security reliability of production efficiency and motor.
