In this linear electric motors, stator is made up of cylindric outer stator and inside stator, and outer stator and inside stator have certain interval.Mover is installed between outer stator and the inside stator, can seesaw.At one of outer stator and inside stator coil is installed, and, magnet is installed on mover, make mover under the effect of coil magnetic field, make axial back and forth movement corresponding to coil.
As shown in Figure 1 and Figure 2, existing linear electric motors comprise stator 10 and mover 20.Stator 10 forms the magnetic field that changes.Mover 20 carries out the straight line back and forth movement under the magnetic field that stator 10 forms.
Stator 10 is made up of outer stator 11, inside stator 12, retainer ring 13.Outer stator 11 is that the center stacks many stator cores in toroidal peripheral surface by cylindrical shape and forms with the loop coil.Inside stator 12 is formed by cylindric stacking by many stator cores 14, and inserts the inside of outer stator 11 at a distance of certain intervals.Each retainer ring 13 is pressed into the two sides of outer stator 11 and inside stator 12 respectively, keeps the circle of each stator 11,12.
As Fig. 2, shown in Figure 3, also the same with the outer stator retainer ring insertion groove 12a that forms of inside stator 12 inserts said fixing ring 13.
Have the existing motor of said structure, its course of work is as follows.
At first, make the coil C energized of outer stator 11, at this moment coil C around produce magnetic field, the magnetic line of force through inside stator 12, enters the opposite side path of outer stator 11 along a side path of outer stator 11, forms magnetic confining field.
When placing each magnet 22 of mover 20 in the magnetic field that coil C produces, the magnetic field interaction that each magnet 22 and coil C produce is pushed into or pulls out by the magnetic direction of coil C, makes mover main body 21 carry out the straight line back and forth movement.
But there are the following problems for above-mentioned existing linear electric motors.With the central part is benchmark, by radial many stator cores is stacked back formation stator 12 one by one, and therefore not only task difficulty is than higher, and operating efficiency is lower, and is easy to generate defective item.
Summary of the invention
In order to overcome the above-mentioned shortcoming that existing linear electric motors exist, the invention provides a kind of linear motor stator electric structure, by improving the stator core structure of linear electric motors, make assembling operation become easy.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of linear motor stator electric structure is to form with laminating several layers of magnetic core; It is characterized in that, one side of described magnetic core, press outstanding formation of certain altitude by punching press and keep spaced protrusions, by punching press magnetic core one side forms described maintenance spaced protrusions by certain altitude when, be recessed to form depressed part in the another side by certain depth, and the maintenance spaced protrusions that makes described magnetic core inserts in the depressed part of adjacent magnetic core and fixes, so as across certain intervals by radial each magnetic core that stacks.
Aforesaid linear motor stator electric structure, wherein magnetic core links to each other by suitable number and forms the magnetic core chain, so that under the state fixing by described maintenance spaced protrusions of the distance between the magnetic core, disposablely stacks by radial.
Aforesaid linear motor stator electric structure, wherein in order to press radial fixed magnetic core, described maintenance spaced protrusions is positioned at upside position or the downside position near the inside portion during by radial stacking.

Embodiment
Below, with reference to accompanying drawing, linear motor stator electric structure of the present invention is elaborated.In the following explanation, the parts identical with existing structure adopt identical symbol.
As Fig. 4, Fig. 5, shown in Figure 6, the linear electric motors with stator structure one embodiment of the present invention are made up of stator 10 that forms magnetic field and the rotor 20 that carries out back and forth movement under the effect in stator 10 magnetic fields.
Stator 10 is made up of outer stator 11, inside stator 112, retainer ring 13.Outer stator 11 is that the center stacks many stator cores in toroidal peripheral surface by cylindrical shape and forms with the loop coil; Inside stator 112 is formed by cylindric stacking by many stator cores 114, and inserts the inside of outer stator 11 at a distance of certain intervals.Each retainer ring 13 is pressed into the two sides of outer stator 11 and inside stator 112 respectively, keeps the circle of each stator 11,112.
As shown in Figure 4, also the same with the outer stator retainer ring insertion groove 112a that forms of inside stator 112 inserts said fixing ring 13.The present invention by punching press, presses outstanding formation of certain altitude and keeps spaced protrusions 115, and make above-mentioned maintenance spaced protrusions 115 and face magnetic core 114 combinations mutually, so that apart certain intervals is by radial each magnetic core 114 that stacks on stator core 114.When stacking magnetic core 114, above-mentioned maintenance spaced protrusions 115 is positioned at upside position or the downside position near the inside portion by radial.In more detail, by punching press a side forms above-mentioned maintenance spaced protrusions 115 by certain altitude when, be recessed to form depressed part 115b in the another side by certain depth, and fixing among the protuberance 115a insertion depressed part 115b that keeps spaced protrusions 115.
Above-mentioned magnetic core 114 links to each other by suitable number and forms the magnetic core chain, so that disposablely make its formation inside stator that joins end to end by radial curling magnetic core chain.Usually stack 244 magnetic cores 114 and form the magnetic core chain.
The linear electric motors course of work of the invention described above is identical with existing linear electric motors.Below, the process that forms inside stator 112 is elaborated.
As shown in Figure 5, keep spaced protrusions 115 that the right quantity magnetic core 114 that is enough to form inside stator is being stacked when forming inside stator 112 by radial in order to make, be positioned at the upper lateral part or the following side that are equivalent to the inside portion, form by punching press at a certain suitable position of magnetic core 114 and keep spaced protrusions 115.Make each magnetic core 114 keep certain intervals to connect then.At this moment, keep the protuberance 115a of spaced protrusions 115 to insert among the depressed part 115b that is fixed on adjacent magnetic core 114 maintenance spaced protrusions 115.As shown in Figure 6, under above-mentioned state, magnetic core 114 is formed inside stator 112 by radial stacking, in retainer ring insertion groove 112a, insert retainer ring 113 then, fix.
The present invention stacks the right quantity stator core 114 that is enough to form inside stator and forms the stator core chain, form simultaneously and keep spaced protrusions, when being connected, each magnetic core 114 keeps certain intervals each other, and a stator core chain that stacks is by radial bending, the stator core chain is linked to each other from beginning to end, form inside stator 112.And with the fixing inside stator 112 of retainer ring 113, thereby be easy to carry out assembling operation.
The invention effect
Linear motion actuator stator structure of the present invention stacks the right quantity stator core that is enough to form inside stator Form the stator core chain, form simultaneously the maintenance spaced protrusions, keep each other one when each magnetic core is connected Decide the interval, and the stator core chain that stacks by radial bending, the stator core chain is linked to each other from beginning to end, Form inside stator. And with the fixing inside stator of retainer ring. Thereby be easy to carry out assembling operation, reduce Manufacturing cost.
In addition, because the magnetic core chain that each magnetic core link to each other is formed is by the radial inside stator that curls into, can To prevent from taking place in the assembling operation situation of magnetic core damage or assembly failure, improve packaging efficiency.
