Description
Technical field
The utility model motor manufacturing equipment technical field, it is specifically a kind of to be used for rotor core welding tooling.
Background technique
For the various aspects such as the operation of motor, iron core manufacturing process is the live part of motor, and to its each side
For the performance in face, there is very big influence.The manufacturing process of iron core in motor is divided into two parts by us, first is that punching
Manufacture, second is that the manufacture of iron core press fitting.There are universal architecture and tinertoy structure, punching punching work for the structure of high-speed motor punching
Skill and mould structure are almost the same, and miniature high-speed motor mostly uses rushes process program again.Mould structure uses the progressive die, general knot
After structure sheet punching press must monolithic laminate, with laminating tool press machine complete, because laminating tool axis has key, outer groove has positioning
Stick, therefore can get high-precision iron core.And tinertoy structure, it is very important a parameter or performance.And in different iron cores
In manufacturing process, there are a variety of different form structures in the tinertoy structure of motor stamping again.
Tinertoy structure type is divided into two kinds: the first is close stacked, i.e. the groups of iron core of tinertoy does not need outside mold again
Pressurization, depanning are that can reach the binding force of iron core tinertoy；It is for second half close stacked, when depanning between the core stamping of tinertoy
There is gap, it is also necessary to which repressurization just can guarantee binding force.Tinertoy structure punching using the progressive die can Lian Chonglian be stacked in stamping procedure
It is primary to complete.Its high production efficiency, but iron core is not contour, iron core verticality, unevenness degree cannot be guaranteed.And stacking factor is low, directly
Connect influence power of motor.It is not that punching thickness difference causes the main reason for contour generation, perpendicularity difference main cause is tinertoy button
Piece convex portion size is inconsistent and raised not close with mating recesses, causes iron core unevenness degree and the error of perpendicularity.Due to height
Speed motor power density is high, compact-sized, and dynamic balancing can only remove material in end ring, therefore initial unbalance, is greater than 10 grams
When, motor quality is directly affected after end ring material removal, dynamic balancing is caused to make not only to influence end ring intensity less than G1 class precision,
And cause noise when motor rotation, more even rotor is caused to scrap.If the welding process of rotor is not to rotor core
Pressurization sizing is carried out, the rotor shapes error after welding will increase again.
Utility model content
In view of the above-mentioned problems, the purpose of this utility model is to provide one kind to press in the welding process rotor
Tight and constraint welding tooling.
In order to achieve the above objectives, using following technical scheme.
A kind of rotor core welding tooling, including press machine, clamp nut, welding pressure cylinder, welding pressing plate, pressing sleeve, welding
Axis, welding pedestal, the welding axis are fixedly connected on the upper surface of welding pedestal, and the external cylindrical surface for welding axis is equipped in parallel
In its axial positioning key, the positioning key is used to limit the punching covered on welding axis, the upper end of the welding axis
Screw rod equipped with pressing sleeve and with the cooperation of clamp nut screw thread, the clamp nut by pressing sleeve to the ring heart of the end ring of rotor into
Row compress, the welding pressing plate and the welding axis are coaxial, placement end ring end face on and pass through press machine, weld pressure cylinder into
The compression of row end ring.
The cross section of the pressing sleeve is T-shaped.
The pressing sleeve is that the T shape set formed is docked by two L shape steel bushings, and the L shape steel bushing turnover of middle and lower part is in end ring
Ring heart cooperation.
Welding tooling is completed in platform over-assemble, end ring, iron core is successively being put, is putting another after having worn conducting bar
End ring will be moved to integrally in hydraulic press and be pressurizeed after bleeding off pressure set, welding pressing plate and welding pressure bucket on end ring, using clamp nut into
Row locking.Iron core height, not contour, verticality are detected under stress.Reach release after requirement.
Compression positioning is carried out to rotor core in welding procedure by the welding tooling, the rotor core height after welding
Error and verticality are smaller；Small, the dimensionally stable that ensure that rotor core deforms in welding, improves the performance of motor.
