The sheet metal of multiple positions is integrally designed.As shown in Figure 6 and Figure 8, yoke portion 101 and the ipsilateral gold of teeth portion 102 will can be set to
Belong to piece, is integrally formed with the sheet metal on the facade that is set to each 102 the same side of teeth portion and is perpendicularly to the direction of movement.Specifically
, as shown, integrally formed sheet metal 5 includes yoke portion sheet metal 501, teeth portion sheet metal 502 and groove portion sheet metal
503, wherein yoke portion sheet metal 501 is connected to yoke portion bottom plate 401 for covering, and teeth portion sheet metal 502 is for covering connection
On teeth portion bottom plate 402, groove portion sheet metal 503 is for being covered on groove portion bottom plate 403, and yoke portion sheet metal 501 and teeth portion gold
Belong to the same side that piece 502 is located at iron core 1, the groove portion sheet metal 503 for covering each teeth portion is respectively positioned on the same of teeth portion
Side.Match with floor structure above-mentioned, as shown in figure 8, the sheet metal 5 for being located at 1 two sides of iron core is arranged independently of each other, i.e.,
Positioned at the other side of iron core 1 yoke portion sheet metal and teeth portion sheet metal and be covered on the facade of the teeth portion opposite other side
Groove portion sheet metal, which is also integrally formed, is designed as one piece of sheet metal, is located at the phase of the integrally formed bottom plate in the iron core other side as a result,
It can partially should be covered by the sheet metal.By attached drawing 8 as can be seen that the structure of two integrally formed sheet metals
Can be set to it is identical, during installation, it is only necessary to will be installed after one of 180 ° of rotation from the other side.
As shown in Figures 9 and 10, the bottom plate 4 and outside of sheet metal 5 is plastic forms the insulation framework 6 connecting with iron core 1, around
Group 3 is wound in outside insulation framework 6.Specific implementation can be that after pasting sheet metal 5 on bottom plate 4, will be coated with bottom
The linear motor unit of plate 4, which is placed in die cavity, completes second of plastic, formation insulation framework 6.It is secondary it is plastic can be by metal
Piece 5 is secured on bottom plate 4, with rib 404 and groove gluing, sealing, forms the coolant flow channel 2 of sealing.
As shown in figure 11, it after the completion of second plastic, is rolled up in the teeth portion 102 for the iron core 1 for being coated with insulation framework 6
