One end is connect with fixing end.
Detailed, bobbin winder base 30 has the seam allowance cooperated with iron core 10, has screw hole on iron core 10, iron core 10 passes through screw
It is connect with bobbin winder base 30 and is located at stop portion, iron core 10 can be rotated with bobbin winder base 30.Iron core 10 is that punching laminates and leads to
Cross what a pull rod was welded and fixed, and solder joint, on the both ends end plate of iron core 10, intermediate punching is only by pressing force and pull rod
Tube bank.It positions rib 41 and backing plate 43 is detachably connected by screw.By tightening screw, rib 41 and 43 energy of backing plate are positioned
Enough in conjunction with the effect of the seam allowance of above-mentioned bobbin winder base 30, punching is compressed together, is reinforced iron core 10, is avoided 10 stress deformation of iron core.
Detailed, positioning rib 41 includes the slot wedge mould portion 412 for reserving slot wedge vacancy 101 on iron core 10.Slot
The size in wedge mould portion 412 can according to need the slot wedge vacancy 101 that reserves to determine, help to produce size more
Accurately product.
Specifically, including: in the step of coiling 20 on iron core 10
Insulation 60 is set in the pad of iron core 10；
Conducting wire is successively wound on to insulation 60 is outer and brush insulated paint and forms coil 20 on conducting wire in winding process；
The package insulation 60 on the outside of coil 20 after the completion of coiling.
It should be noted that object of the insulation 60 for the wire insulation for coil 20 of the prior art, such as can be
It is more than the insulating pieces of subsequent baked and cured temperature that highest as Kapton, which allows operating temperature, such existing
The existing object of technology does not interfere to understand for technical personnel, therefore does not repeat it.
Detailed, backing plate 43 has crossed beam trunking, and conducting wire is passed through crossed beam trunking first and is compressed, then starting coil winding machine will lead
Line is successively directly wound on iron core 10.
Sequentially be specifically, coattail end towards fixing end coiling first layer, after first layer coiling fixing end pass a bridge around
The second layer processed；The second layer is from fixing end towards coattail end coiling, in coattail end gap bridge coiling third layer after second layer coiling；The
Three layers from coattail end towards fixing end coiling.
Due to there is positioning rib 41, there can be support in coattail end coiling conducting wire, avoid building height without foundation, further make
With being to prevent 20 turned-down edge of coil.
In addition, to obtain locating clip next for coattail end, iron core 10 will not occur tooth and rise phenomenon, tie during coiling conducting wire
Bobbin winder base 30 is closed, the pulling force that iron core 10 is received when coiling is acted on bobbin winder base 30, iron core 10 will not be because of conducting wire
Pulling force deformation.
Specifically, the step of coil 20 is co-located with iron core 10 includes:
The first locating part is cooperated jointly to clamp coil 20 and iron core 10 using the second limit assembly 50；
Second locating part includes limiting cushion block 51 and clamping plate 53, and limiting cushion block 51 is located at the opposite two sides of iron core 10, and
And the end sections of limiting cushion block 51 are bonded with backing plate 43, the other parts of limiting cushion block 51 are bonded with coil 20, and clamping plate 53 is set
It is placed in the other opposite two sides of iron core 10 and is detachably connected with limiting cushion block 51, clamping plate 53 is bonded with coil 20.
Wherein, clamping plate 53 and limiting cushion block 51 are also to be detachably connected by screw, by tightening screw, are made
It obtains clamping plate 53 coil 20 is pressed on iron core 10, to achieve the purpose that 20 outer width size of control coil.
Specifically, baking by coil 20 and the iron core 10 after positioning and solidifying integral step and include:
First limit assembly 40, the second limit assembly 50 and the first limit assembly 40 and the second limit assembly 50 is common
The coil 20 and iron core 10 of clamping are put into baking oven and carry out baked and cured.
Detailed, the temperature of baked and cured is 150 DEG C -170 DEG C, and the time of baked and cured is 2-3 hours.
In baking process, 20 gelatinization of coil and make coil 20, iron core 10 and insulation 60 solidification be integrated.
It is detailed, the thermal expansion coefficient and iron core 10 of the thermal expansion coefficient of the first limit assembly 40, the second limit assembly 50
Thermal expansion coefficient it is identical；
The thermal expansion coefficient of the thermal expansion coefficient of first limit assembly 40 and the second limit assembly 50 is respectively less than the heat of conducting wire
The coefficient of expansion.Can ensure in this way can be by coil 20 and 10 baked and cured of iron core at an entirety and in baking process
Middle influence positioning clamps.
By above-mentioned series of process step, band winding iron core manufacturing method can produce compact shown in fig. 5
Band winding iron core 200.After the step of baked and cured, the second limit assembly 50, the first limit assembly 40 are successively removed is
It can be taken off product, since coil 20 and iron core 10, insulation 60 have been cured integral, when removing, coil 20 will not collapse
Side phenomenon and the sizing of the size of coil 20.
Because the mover of existing linear motor is that the iron core 10 by multiple with winding splices and combines, structure is tighter
It gathers, the size Controls of 10 winding two sides of iron core is required very high, and of the invention produced with winding iron core manufacturing method
Compact the outer width size of control coil 20 and can also can prevent turned-down edge well with winding iron core 200, in this way
Compact to assemble the mover come with winding iron core 200 be to have very much quality assurance, two adjacent compacts band winding iron
Cooling tube can be just placed between core 200.
Further, such compact can have the slot wedge vacancy 101 for meeting requirement with winding iron core 200, can
To be used to be used to the tight cooling tube of inserting slot wedge pressure, slot wedge and cooling tube in assembling and inlay all be the mature prior art, because
This is repeated no more.
It is of the invention with winding iron core manufacturing method by being positioned to the iron core 10 with dovetail, and directly in iron core 10
Upper coiling 20 further positions the iron core 10 after making coil 20, the outer width size of control coil 20, and will
Iron core 10 is put into togerther baking oven with clamping mold and is baked, and coil 20, iron core 10 and insulation 60 are obtained in size
It is solidified into an entirety under conditions of control, finally produces compact band winding iron core 200.
Compact band winding iron core 200 is compact-sized, very close to each other, 20 ruler of coil between band dovetail iron core 10 and coil 20
Very little control is good.It is more suitable and is assembled into mover, good effectiveness is played in linear motor.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
