Description
Technical field:
The utility model relates to a kind of assembly toolings of Large-power High-Speed motor outside plug type splicing stator.
Background technique:
The stator of Large-power High-Speed motor has some special properity features, therefore there are some for its manufacturing process
Difficult point." outside plug type of Large-power High-Speed motor splices stator structure " of our company solves the system of Large-power High-Speed motor stator
Problem is made, but itself also proposes special requirement to assembly tooling and technique.
1, (interpolation type) splices stator structure:
Prefabricated copper bar coil be in heavy-duty motor through frequently with a kind of stator winding form, have assembly process process
Well, the advantages that high temperature resistance is good, carrying electric current is big, winding volume is small.
Spliced stator is also the common method in electromechanics trade, commonly used in the motor of major diameter, multi-pole, shallow slot depth
Stator, for reducing silicon steel blinking scrap, reducing blanking die manufacture difficulty.But splicing stator is still according to " after first stator
Stator discrete piece is first spliced cyclization by the assembling process of coil ", then by coil from interior measuring leading groove.Because of this kind of stator
Big inner hole, shallow slot make them not need special assembly technology deeply.
2, outside plug type splices stator structure:
Because the revolving speed of high-speed motor is high, the rotor magnetic pole number of the high-speed motor of equal-wattage is few, root diameter is small,
The big frequency of stator current is high.Therefore the internal diameter of high-speed motor stator is smaller, wire casing is deeper, every wire bushing the number of turns is more.
These features result in the prefabricated copper bar coil of Large-power High-Speed motor thicker harder, and must be first in assembly
It is reversed into twisted shape and fills in stator inner hole again, and need to fill in several coils in stator inner hole simultaneously, be then sequentially inserted into
Wire casing.(note: because can mutually laminate between stator coil, whens last several installations, must be several removal lines at first
Slot.Multiple coils while plug are had in inner hole.)
When motor speed is increased to 10,000 turns or more, the structure size of stator and coil has made this " after first stator
Coil " assembly method can not be achieved substantially.
In order to solve the problems, such as the manufacturing process of stator of high-power height motor, we have proposed a kind of stator structures to assemble
Prefabricated copper bar coil in turn, by the way of " stator after first coil ", i.e., is first inserted and fixed by sequence from outer side to center
On special tooling, stator is inserted on the outside of coil then and is spliced into the domain.
In order to be distinguished with the splicing stator structure of this patent, direction of insertion when we assemble according to coil, by this elder generation
It assembles stator, coil and is known as " interpolation type splicing stator " from the splicing stator of inside insertion.And the first dress of this patent is from outside to inside
It assembles coil, be inserted into the splicing stator of stator from outside to inside again referred to as " outside plug type splicing stator ".
Although outside plug type splicing stator structure is able to solve the manufacture problem of Large-power High-Speed motor stator, but itself
There is a problem to need to solve --- i.e. in assembling process, coil block does not have the bearing of stator；And coil block itself is
It cannot be guaranteed that be mutually located, positioning and guiding can not be provided for stator inserted sheet.
Therefore need to design a kind of assembly of dedicated assembly tooling for Large-power High-Speed motor outside plug type splicing stator.
Utility model content:
The utility model is provided outside a kind of Large-power High-Speed motor in order to solve the above-mentioned problems of the prior art
The assembly tooling of the formula of inserting splicing stator.
Technical solution used by the utility model has: a kind of assembler of Large-power High-Speed motor outside plug type splicing stator

It is formed with coil locating slot between adjacent two coil brace on the every side end face of frame, two end cap is respectively fixedly connected in centre frame
Two sides, and every side end cap correspondence the coil brace of the side is fixed on centre frame.
Further, the axis class formation that the centre frame is made of three sections of cylindrical bodies, including mediate cylindrical and side circle
Cylinder, two side cylindrical bodies are respectively fixedly connected on the both sides of the face of mediate cylindrical, and side cylindrical body and mediate cylindrical
Coaxial arrangement.
Further, a circle pin hole is respectively provided in the both ends of the surface of the mediate cylindrical, pin hole is located at the outer of side cylindrical body
Side.
Further, the coil brace includes integrally formed scallop and rectangular portion, and rectangular portion is placed in scallop
Bottom is equipped with shop bolt in the bottom of rectangular portion.
Further, a side end face of the end cap is equipped with round boss, several limiting slots are equipped on boss.
The utility model has the following beneficial effects:
1) the utility model solves in outside plug type splicing stator assembling process, and coil block itself cannot keep position
Problem ensure that the feasibility of stator assembly.
2) assembly tooling is simple and reliable for structure, facilitates manufacture.
3) tooling may be reused: the structure of tooling ensure that coil brace can easily be torn open from stator finished product
It removes, therefore tooling may be reused.
3) labor intensity of workers is low: tooling axisymmetricly structure, and is all fixed on cylindrical centre frame.Therefore
Assembly tooling can be along centre frame rotation.This can reduce the carrying of workpiece, overturning labour, operation convenient for assembly, and can be with
The shift action for reducing worker itself, substantially reduces labor intensity.
4) high production efficiency: in assembly technology, most of operation is carried out from the outside of tooling.Therefore worker operation
Convenient, station arrangement is convenient, and allows more people while assembling, so as to improve production efficiency.
